Analysis of metal ore finding direction and geological characteristics of deposits

  Mineral search mode and direction of mineral search

  This paper takes the gold ore in an area as an example, where there are mainly two types of gold ore, namely, fracture zone alteration rock type and shear zone alteration rock type, and the output and distribution of each deposit (point) are subject to certain geological factors and have their own signs of finding ore. Among them, the former is mainly represented by the large plate gold mine, while the latter is mainly represented by the large scale Pai Shan Lou gold mine.

  (I) Stratigraphic lithology signatures

  The stratigraphic control characteristics are the distinctive features of gold ore in this region. The case rocks and deep-formed intrusive bodies of the Taurian period directly influence the fracture zone alteration type and alteration type gold ore, and their lithology is dominated by hornblende and long-engine chyolite system.

  (II) Magmatic rock signatures

  The ring structure in remote sensing interpretation is one of the ore finding signs of gold in this area, which is obtained by the geological proof of gravity and aeromagnetic. It is mainly due to the fact that the Mamluksan rock body and some small rock bodies to its north are connected together at its depth, thus leading to the fact that most of the gold ores in this area are above the hidden rock bodies. In addition, the frequent activities of magmatic activities in the area provide water and material sources as well as some heat sources for the formation of metal ores, which to a certain extent has given rise to the formation of metal ores. The affiliation of veins and small rock strains with the main rock body, the possibility of searching for new veins in the contact zone on both sides of medium and acidic intrusions or veins.

  (C) Tectonic sign

  The tectonic control of gold ore in this area is obvious, from the distribution of mineralization zones to the formation of deposits and ore bodies are controlled by tectonics at all levels. The regional deep major fractures are both ore-conducting structures and control the distribution of ore fields and deposits: the widely developed secondary near-EW and NW fractures control the ore bodies and ore belts. The former is early compressional-torsional and larger in scale, often forming a north-west-trending stacked tile recoil (mask) thrust structure. With the help of its pushing and shearing effect, the area will form a large scale of mylonitization zone and extrusion shear lamellarization zone, and the extensional slip tough-brittle activity of these tectonic weak zones in the late stage makes it become the guide and ore-holding structure of the Pai Shan Lou type and large plate type positive shear zone type gold ore; the latter is mostly tensional-torsional, smaller in scale, and often forms a group of NW directional right rows of geese column fracture zone, which is The main guide and ore-holding structure of alteration rock Ying vein type gold ore.

  Stratigraphy and mineralization

  The stratigraphy exposed in the area is relatively simple, including: Taiyu metamorphic case rocks, the Great Wall System and the Jixian System in the Middle Paleo Period, the Jurassic and Cretaceous Systems in the Mesozoic Period and the Fourth System in the Cenozoic Period. The former is divided into four group-level lithostratigraphic units, and the latter can be divided into five, which are distributed on or around the metamorphic deep-formed rocks of the Tauric, and are mostly tectonically in the form of tectonic sheets or flysch of different sizes, all of which are a combination of endogenous carbonates and land-derived clastic rocks. The rest are mainly dolomite, dolomitic chert and feldspathic quartz sandstone. Pai Shan Lou and other gold mines in the area, in the gold mineralization process in the region may play a physical and chemical barrier role, so as to promote the mineralization process. This is related to their geographical location, are produced in the middle and upper metasedimentary stratigraphic distribution of the nearby section of the Taurian metamorphic deep shear parts, and by the middle metasedimentary strata constitute the top plate of the deposit.

  Magmatic rocks and mineralization

  Considering the rock chemistry, mineral combination and paragenetic characteristics of the rocks, it is presumed that the granite in this area is mainly of type I, supplemented by type S. The magmatic rocks in the area are more developed, and the exposed magmatic rocks include granitic rocks of Taiyang Dynasty, Hualixi Stage amphibolite, Yanshan Stage granite and so on. The intrusive rocks have different intensities and scales in different periods, among which the most intense and widely distributed in the Tertiary and Mesozoic periods, while the Mesozoic intrusive rocks are the second in scale and intensity. In addition, the Taiyan and Mesozoic magmatic rocks also influenced the formation of gold ore to some extent.

  (I) Tauric metamorphic deep-formed rocks

  The Tauric metamorphic rocks in this area are composed of the Baiyuan Gneiss and the Tauric Xiaomaling Gneiss, with a north-northeast trending belt. The former lithology is diagenetic and granulitic gneisses. The latter rocks are mainly composed of quartz amphibolite, orogenic granitic gneisses and inyun amphibolite gneisses, of which inyun amphibolite gneisses are the main constituents. The rocks are all subjected to ductile shearing and most of them are transformed into mylonite-like rocks. In addition, there is also a small amount of Suizhong gneiss, whose main lithology is granitic gneiss.

  (B) Middle Age intrusive rocks

  The gold ores in this area are distributed in a certain range around the Mesozoic intrusive rocks, and mostly formed in the Mesozoic. The area is composed of two units, both of which are in the northern part of the area, the lithology of the former is gneissic oblique granite, and the latter is gneissic diorite.

  (C) Mesozoic intrusive rocks

  1、Early Permian small Oley Yingzi super unit: mainly distributed in the northern part of the area, locally exposed, composed of medium-grained potassium long granite. In addition, there are also a small amount of quartz amphibolite outcrops; 2. Late Triassic rocks: a well-developed unit in the area, lithology is mainly amphibolite; 3. Early Jurassic Shaoleng super unit: composed of four units in the area, mostly in the form of rock strains, lithology is mainly diorite and granite amphibolite; 4. Middle Jurassic Haitang Mountain super unit: mainly in the northern part of the Pai Shan Lou gold mine, composed of two units, lithology 5、Late Jurassic Lushan superunit: mainly composed of three units, with granite, granodiorite and diorite as the main lithologies.

  Geological structure and mineralization structure

  The geotectonic position of this area is Yanshan platform fold belt – Liaoxi platform trap – Beizhen bulge, which belongs to the tectonic domain of the coastal Pacific Ocean. Therefore, the basic outline of the regional tectonics is a basin-ridge tectonic combination consisting of a Mesozoic volcanic rock fault basin and a tectonic miscellaneous rock uplift belt spreading in a north-northeast direction. Specifically, the inner edge of the west side of the uplift zone is the Jinzhou-Harr set of ductile fracture zone, the east edge of the uplift zone is the west edge of the Tanlu Fault influence zone, and the west side of the Beizhen Bulge is the Jinzhou-Harr set of fractures. Among them, the main controlling factor of gold ore in this area is the uplift area and the Mesozoic brittle and ductile fracture structures developed in it.

  (I) Brittle fracture structure

  The NE-NNE fractures are mainly located between the Beizhen Bulge and the eastern edge of the Fuyi Basin, forming an NNE-oriented fracture zone about 10 km wide and 180 km long, which is regionally known as the Jinzhou-Hal Crustal Fault. It is characterized by multi-phase activity, mainly compressional-torsional, followed by tensional-torsional. The fracture surface is mostly NW-dipping with an inclination of 60°~80°, in which extrusion lamellae, fault mud and tectonic lenses can be seen. The fracture has a direct influence on the occurrence, development, evolution and volcanic eruption and deposition of Yanshan-age fracture basins. Secondly, the near-EW-oriented fractures are mostly sporadically distributed in the terrigenous bodies of the Tauric, often cut by NNE and NW-oriented fractures, which are small in scale and compressive.

  (ii) Ductile shear zone

  The north-northeast ductile shear zone in this area is large in scale, mainly composed of mylonite and various types of tectonic schist, distributed in the NNE direction, tilted north-west, dip angle of 30 ° ~ 70 °, about 150 km long and more than 10 km wide. The rocks are strongly lamellarized, with quartz elongated, feldspar in a residual patchy and eyeball-like pattern, and dark minerals arranged in an obvious direction. The rocks are spatially zoned with obvious intensity, from the edge of the deformation zone to the center in the order of fractured rock zone, coarse vuggy rock zone and vuggy rock zone.

  In summary, when conducting research on the direction of metal ore search and geological characteristics of deposits, for metal ores with good mineral quality conditions, we should take into account the conditions of ore-control structures, the presence of ore-forming strata, and the distribution of ore-forming-related information, and make full use of known ore-forming laws for mineral prediction on this basis. In addition, for geological prospecting work, its successful implementation is inseparable from advanced scientific research and survey technology on the one hand, and secondly, it is necessary to ensure that geochemical methods, geology and geophysics are in the best combination.

On the construction technology of extruded concrete sidewalls in the construction of housing buildings

  Extruded concrete sidewall construction technology, as an important construction technology, occupies an important position in the building construction system, this technology on the basis of traditional construction technology to carry out certain technology-based improvements, and then the traditional construction process for a certain integration, delete the complex process, but the use of a more practical method to a more rapid form of construction to the progress of the project as well as The degree of refinement.

The concrete implementation of this construction system has certain influencing factors, so we need to have a comprehensive understanding of this construction technology, and then from the level of technical points to avoid the risk factors of the construction link, so that this construction system can be carried out and implemented more reasonably.

  1 Concrete extrusion sidewall brief description

  For the extruded concrete sidewall construction technology, it is by drawing on the basic principle of extruded sliding die in the road gardening project in the roadside machine, through the role of mechanical extrusion pressure to form the wall, and then use the reaction force to move.

The concrete sidewall construction method is to obtain an asymmetrical trapezoidal semi-permeable concrete retaining wall by extruding the sidewall machine before each layer of bedding material is filled, then laying the corresponding dam material on its inner side according to the design, and using a vibrating mill plane for rolling, and then repeating the above process after passing.

  2 Advantages of Extruded Concrete Sidewalls

  The asymmetrical trapezoid shape is the main shape of the extruded section of the sidewall, and is connected by means of articulation, which allows the sidewall to adapt well to the deformation of the bedding area, effectively preventing the appearance of empty walls at the bottom due to unqualified rolling, and effectively controlling the adverse effects on the slab surface.

The technology effectively combines the joints between the bedding layer and the sidewall to make a reasonable design of the construction process, which can effectively ensure the quality of the project after the crushing. Extruded concrete sidewall construction technology is simple, quick and easy to construct, and easier to master. At the same time, the extruded sidewall has a certain restrictive effect on its upstream slope, without overfilling the bedding material, and replaces the original slope rolling with horizontal rolling, which not only improves the construction quality of the bedding material, but also improves the safety of construction.

  3 The main points of extruded concrete sidewall construction technology in the construction of housing buildings

  3.1 Make good preparation before construction

  Before the start of the specific construction process, the construction tools and the overall environmental conditions should be sorted out to carry out the next construction work in an orderly manner after the preparation process is properly implemented. The specific preparatory work includes the following links.

First, the construction of the base surface of the leveling repair work, this work requires us to first before the construction of the construction of the bedding material for a certain leveling, and then ensure that the construction link is on the plane, this practice can enhance the stability of the construction surface, and on this basis, the height of the drop to a more scientific and reasonable control, so that the next construction link can be carried out smoothly.

Base leveling, in the paving of the bedding material must be strict control of its flatness and height difference, and then leveled by the artificial rope pulling, requiring the height difference after rolling must be controlled within 3cm, for some parts do not meet the requirements, it must be processed and meet the standards before the extruded side walls can be placed on the construction.

  3.2 Side wall extrusion molding link perfection process

  The sidewall is closely related to the stability of the building, so the sidewall and the related building system should be extruded before construction to facilitate faster solidification of the sidewall, and in this process, strict attention should be paid to the control of the extrusion force, and the implementation level of this link to arrange special management and control personnel to carry out all-round control of the complete implementation of the extrusion process, so that the speed of the corresponding extrusion force machine This speed is neither too high for the unbalanced force nor too low for the damage to the side walls caused by the strong force.

When the mixing truck is unloaded, the coarse aggregate must be discarded when the material is just discharged, and then put it into the extruder’s receiving bin when the material is more evenly discharged, and to ensure that the extruder and the mixing truck can walk synchronously and unload the material manually. The extruder must ensure that the deviation between the extruder and the control line is within 2cm, which is to ensure the flatness of the slope of the extrusion wall.

  3.3 Leveling of the construction site

  The construction site construction has a direct connection and influence on the actual construction project, so the construction site surface engineering construction system must be carried out and implemented carefully. Generally speaking, the actual flatness of the mat surface will affect to a certain extent the actual size of the appearance of the crimped edge wall after the completion of the molding, the flatter the mat surface, the more the corresponding wall surface will be in line with the relevant provisions of the project, while, on the contrary, the mat surface puddle situation, the implementation of the flatness of the wall process will also be affected to varying degrees.

Therefore, on this basis, we have to provide a certain level operating environment for the specific operation of the extruder, so that the extruder in the actual engineering environment, to obtain a more ideal construction work layer. At the same time, during the construction, the flatness and height difference of the previous layer of extruded sidewalls and bedding material after filling must be checked accordingly, and if it does not reach the standard, it needs to be manually trimmed, leveled and compacted.

  3.4 Concrete control of construction quality

  The actual construction process of the extruded concrete sidewall is bound to have a certain error imbalance phenomenon, and the cause of such phenomenon is usually the construction level of the specific constructive problems, under the influence of these problems, the extruded wall in the design of the appearance and upstream slope construction will appear after the formation of a certain error and the error is often relatively large, and thus exceeded a certain binding standard.

In response to this situation, a certain degree of treatment must be carried out in a timely manner, but the actual stress repair mechanism of the implementation level often appears to be a certain situation, in the specific sudden situation occurs, to try to avoid it. At the same time, for the bedding material plane, it is the base surface of the extrusion wall construction, while the extrusion wall is the side mold of the bedding material construction, thus it can be seen that their influence on the construction quality is interrelated. The flatness of the bedding material construction has a direct impact on the smoothness of the extrusion machine walking, which also has an impact on the outer slope of the side wall.

  Conclusion

  In conclusion, the execution system of concrete building construction is complex, so the actual extruded concrete sidewall construction technology in the face of these circumstances is difficult to have a specific implementation. Therefore, we need to simplify the corresponding construction process based on a comprehensive understanding of the specific implementation characteristics of extruded concrete sidewall construction technology, so that the implementation of this technology is more effective and rationalized.
In this way, we can fully carry out the construction of extruded concrete sidewall construction technology on this basis, and this is conducive to the comprehensive promotion of China’s construction industry innovation. It is conducive to making people’s living and working environment more comfortable, and also conducive to the construction of the corresponding building system in all aspects, and thus, on this basis, to promote the constructive development of the relevant economic system in China.

Construction technology of concrete structures in civil engineering buildings

The city is constantly developing, and the requirements for the quality of urban buildings are getting higher and higher. For the construction technology of concrete structures there are still many places for people to further improve, we must understand the characteristics of concrete structures and the methods and conditions and precautions for the use of concrete in the construction process. These are the most basic elements that should be available at the beginning of the construction and during the process.

Advantages of concrete structures

Concrete structure is a new type of structure composed of plain concrete structure, prestressed concrete structure and reinforced concrete structure, with concrete as the main material and some other related materials. The concrete used in modern civil engineering construction is also called concrete, which is a mixed cementitious material in which cement, sand, stone, water and other materials are mixed in a certain ratio and then cemented together for the implementation of construction projects in the construction industry.

Concrete is widely used in the modern construction industry, bulk concrete as one of the important materials in civil engineering construction. The reason why it can become one of the more widely used materials in the civil engineering construction industry today is also based on a certain basis, the following authors list some of the advantages of concrete materials themselves.

  1. Easy to make. Concrete structure in the production and production of the process required is relatively simple, technically difficult and very easy to operate.
  2. Easy to source. The substances that make up concrete structures are widely available in nature.

3, cheap. Because of the easy source of concrete structure and the simple production process, the price is much lower than other construction materials, and is favored by the construction industry.

4、Stable nature. The durability and fire resistance of concrete structures are very good, in line with the requirements of construction.

5、Good performance. Concrete structure and the brick structure used to be compared, its seismic resistance and adapt to bad weather and natural disasters are better performance.

6, good plasticity. In the process of civil engineering construction, the most used technology is the overall pouring technology, this technology is for the concrete structure and the development of this nature in the project is very convenient to use, and good integrity

7, the performance is easy to adjust, easy to take materials, conducive to meet the use of various types of projects.

8, concrete environmental protection, can use slag, cinder, coal ash and other industrial waste to its production.

The main problems in the construction of concrete structures in civil engineering buildings

There are certain problems in the construction of concrete structures in civil engineering buildings, what are the common problems, and how should we solve these problems is what we will discuss below.

1, the quality of concrete materials is not qualified

With the continuous progress of social technology, China’s construction industry engineering standards are becoming increasingly strict, the past manual mapping technology is not able to meet the requirements of the construction of building quality. In the manual testing of construction materials, often because the procurement staff to purchase materials do not meet the strength requirements of the concrete structure itself or inspector inspection is not strict enough, resulting in a crisis in the concrete structure, which makes it difficult to ensure that the modern concrete structure in the field of civil engineering to play the most beneficial role, pulling down the construction technology level of the building industry and the quality of construction products.

Therefore, strengthen the discussion and research on science and technology, improve the construction technology, insist on the introduction of high-tech equipment required in the construction process has become a realistic situation that cannot be ignored.

2、The technology of blending concrete is not standardized

The first study of concrete is blended in the laboratory, its ratio meets the requirements and can be standardized. The reality of the building in construction may not be able to meet the required standards, the reality of the construction environment there are too many uncertainties, and will not be in accordance with the specific requirements of the ratio as in the laboratory, so there will be differences in strength.

Therefore, more efforts should be made to standardize the process of making concrete, so as to achieve the strength requirements of concrete itself.

3、Concrete is prone to cracks in construction

Concrete structure is composed of different kinds of raw materials, concrete as a construction material, will produce cracks for a variety of reasons, cracking can be said to be “multiple” and “common”, because the cracks have led to a decline in the quality of the project has long been commonplace. . In general, we divide the types of concrete cracks into three categories. First, surface cracks, second, penetration cracks, and third, deep cracks in the structure.

Surface cracks are less important to the safety of the building product, because concrete has good durability and easy to adjust its performance. However, deep structural fractures and penetration fractures are different, they can affect the safety of the concrete structure, the integrity is jeopardized, and repair is more difficult.

The causes of cracks in concrete in civil engineering construction

1, building products due to temperature changes prone to cracks

The concrete used in construction will be affected by the external environment and temperature changes inside the structure, with the characteristics of thermal expansion and contraction, the concrete structure will deform, deformation if hindered, its internal will appear stress, when the stress exceeds the tensile force that can be carried by the concrete structure, it will produce cracks caused by temperature.

2、Cracks caused by foundation deformation of building products

Because the geological structure is complex and unpredictable, and the modern geological exploration technology is not well developed, the survey accuracy needs to be improved. During the construction, the foundation will produce vertical uneven settlement or horizontal displacement, resulting in the production of excess stress inside the structure, and this additional stress exceeds the tensile capacity that the concrete structure can withstand, so the concrete structure produces cracks.

3、Cracks caused by corrosion of reinforcing steel

The surface layer of concrete is susceptible to carbon dioxide carbonation, carbonation will be serious erosion to the surface of the reinforcing steel, resulting in a decrease in the alkaline concentration of the concrete retained around the reinforcing steel, the resulting chloride may be the surface of the reinforcing steel oxide film is broken, thus corroding the reinforcing steel, making the area of the reinforcing steel smaller and smaller, the reinforced concrete contact stress point becomes less, the load-bearing capacity of the structure weakened, generating cracks and damaging the concrete structure.

Optimization analysis of the construction technology design of concrete structures

Before the project is about to start, it is very necessary for us to design the construction technology of the concrete structure in advance. In order to make the civil engineering construction progress faster and more effectively the authors have briefly analyzed this.

1、Strengthen the planning of the concrete structure

The procurement of the formwork should be very careful, and the long-term planning should be carried out strictly in accordance with the formwork before construction, and the formwork should be formulated as a special program for the project, and the program should be implemented only after all audits by professionals. In addition to the formwork, the planning of the construction drawings should also be strictly required, the nodes of the frame should be carefully encrypted and tied, the welding part must be cleaned of welding slag, and the tying of the structural plate should have sure measures to increase the bearing capacity of the structural plate.

2、Concrete mixing and maintenance, standardize the construction of unqualified behavior

In the construction of the project concrete to be tight specifications deployment to ensure that the concrete structure has sufficient strength. The right amount of additives and reinforcing materials are added to effectively control the self-shrinkage value of cement and concrete, and the stronger tensile properties of fibers are conducive to improving the cracking strength of the concrete structure. The construction process should be regularly arranged for inspectors to maintain the concrete in large areas. Maintaining the appropriate temperature and humidity is the key to the maintenance of concrete structures, which will make the tensile strength of the concrete structure bearing greater and reduce the occurrence of problems.

Conclusion.

China’s construction industry follows the society in a booming development. The concrete structure is an important building material in the field of civil engineering, but there are still some problems in the application of concrete structure in the relevant buildings, which needs to be further studied and explored.

In the process of construction technology of concrete structure also contains a lot of disadvantages, which makes the safety of construction projects reduced, which people do not want to see. Therefore, we call on the relevant departments to strengthen the supervision and management of civil engineering construction projects, and to strictly control the quality of construction, so that the future of civil engineering construction in China will be more beautiful.

Analysis of management measures for cement concrete pavement defects on rural roads

The normal use and safety performance of road surface are largely affected by the serious impact of cement concrete pavement diseases on rural roads, and analyzing the causes of various pavement diseases and finding the corresponding solution measures have become one of the hot issues of more concern in the engineering community. For different kinds of hazards, to find the corresponding solutions, can be timely and effective treatment of disease, for engineering construction is very meaningful.

1 Crack of broken slab and road panel

1.1 Causes

1.1.1 Cracks appear on the road panel and the cement concrete panel slab bottom debonding is necessarily related. In the construction process of China’s rural roads, usually is not the asphalt intermediate layer laid in the cement pavement structure in the panel. After the seepage of water in the joints, because of the pumping effect of the wheels of traffic can easily lead to the phenomenon of debonding of the cement-stabilized gravel base and the bottom of the cement concrete panel, which will also increase the bending and tensile stresses that the cement concrete panel has to bear, thus accelerating the aging degree of the pavement.

1.1.2 No matching reinforcement in the panel. In some remote places in China, in the process of construction of rural roads, in order to save money, the construction process of cement pavement usually uses plain concrete panels that will not be paired with reinforcement within the panels, and this kind of panels are very easy to crack because of too much load and the factor of temperature fatigue, while the broken panels will also be This type of panel is prone to cracking due to excessive load and temperature fatigue, and the broken slab is also damaged.

1.2 Solution measures

1.2.1 Cracking can cause a single concrete panel to split into 3 or more unconnected pieces. mesh.

1.2.2 We can choose to use modified emulsified asphalt for grouting treatment, which can solve some small cracks in the surface layer of cement concrete slab. cracks.

1.2.3 If there are cracks on the surface of the panel, we can find a 10cm area on the surface of the panel, chisel it out, add Φ6 (Φ8) reinforcing mesh and fill it with new concrete to cover it.

2 The surface layer of the road is broken

2.1 Causes

If poor quality raw materials are selected, or if the concrete is not proportionally matched, or if the construction quality is inadequate, it is likely that the surface damage (e.g. spalling, cracking) will occur on the cement concrete panels of rural roads. Especially in this case, if there are more heavy-duty vehicles or more severe weather conditions, but also increase the degree of damage and damage to the panel.

2.2 Solution measures

Compared with the cement concrete panel with a wide range of damage to the road surface, the cement concrete slab with a lighter degree of damage can be chiseled away 3-5cm cement slab in the damaged area and then a layer of asphalt can be laid on the surface. For cement concrete slabs with more severe damage, 6 to 10 cm of cement slabs can be cut away and maintained with cement concrete of a higher strength level than the pavement. Repair.

3 Panel joints damage

3.1 Causes

Improperly spaced expansion joints or substandard joints can lead to damage to the interconnected cement concrete panel joints. There is such a phenomenon, in the construction process, there are a few units blindly pursuing flatness, thus making the number of expansion joints set to reduce, in the temperature gradient is large, the cement panel will shrink and expand, the first damage will occur in the more vulnerable link joints. If the transmission rod or tie bar at the joint is not set up in accordance with the standard, it will lead to misalignment due to the load, and if it is not repaired in time, then panel fracture or joint material breakage will occur near the joint.

3.2 Solution measures

We must set up expansion joints strictly according to the required documents or standard requirements, and add expansion joints when the spacing of expansion joints does not meet the requirements. If there is a small misstep at the joints, we can use a thin layer of asphalt table to level; if there is a serious misstep at the joints or the interconnected panels have been cracked, then we have to partially clean up the existing panels in a wide range, wait until after the proper setting of the transmission rod, and then lay a new concrete surface layer on the surface.

4 Sinkage of table back

4.1 Causes

The construction process of rural roads, but also inevitably encounter the situation of the bridge, there are two factors will lead to the back of the platform fill the overall tilt of the panel or the bridge head lap, one is the selection of inappropriate materials, and in the construction process is not in accordance with the standard to compact the material. If the bridge head expansion joint waterproofing effect is not good, downward penetration of water will also erode the soil base or grass-roots level, and in another degree greatly deepen the degree of slope of the back of the table road panel.

4.2 Solution measures

When it comes to the tilt of the cement concrete slab at the back of the bridge sink, there are two solutions: (1) to ensure that the work of the waterproofing function of the expansion joint is done to reduce the content of water infiltration; (2) filler such as slurry stone in the sinkage gap at the back of the table, in the place where the settlement of the lap plate tilt is serious, use asphalt mixture to level or redo the lap.

5 Uneven settlement of road panel

5.1 Causes

Road panel has the phenomenon of uneven settlement and roadbed compaction condition and grass-roots strength uniformity is inextricably linked. If the compaction does not reach sufficient standards, then the roadbed will be deformed inconsistently under the action of the car load, and then it will make the cement concrete slab bottom voids; likewise, the grass-roots strength is not uniform is also an important factor affecting the bottom of the road panel voids. The voids promote the degree of plate bottom dehollowing under the coupling action of water and load, which leads to serious uneven settlement of the pavement.

5.2 Solution measures

  For the uneven settlement of the road panel this phenomenon, we should field survey, to determine a good match with the actual repair program, the right remedy. If the strength of the grass-roots level is still lacking, we can take local replacement to fill the way to repair, and at the same time to improve the ability of the pavement to resist water damage, you can choose to sprinkle emulsified asphalt sealer on the contact surface of the grass-roots level and surface layer. Also, if the soil base compaction is detected to be small, it can be locally grouted as a way to stabilize the soil base and minimize the amount of soil base settlement later.

  In short, the causes of rural highway cement concrete pavement disease is multifaceted, may be improper use of roadbed filling materials lead to the sinking or collapse of the roadbed, but also because the soft base is not properly handled, there are also because the backfill of the structure platform back does not meet the standards should be met and other reasons, these will make the service life of the road shortened, the vehicle driving comfort reduced. Thus, it can be seen that the analysis of cement concrete pavement hazards on rural roads is very beneficial and necessary. For the pavement hazards, we should always keep alert and follow the purpose of “prevention-oriented, prevention and control combined”. Once the seeds of pavement hazards are found, we should deal with them as soon as possible to stop the spread and deepening of the disease.
