Description

Technical Field

[0001] The invention belongs to the technical field of road construction, and mainly relates to a paving method of a road paving module used on a rugged foundation. Background Art

[0002] With the popularity of large rubber-wheeled trucks transporting mining materials on underground roads, modern high-output mines have abandoned the previous practice of laying narrow tracks and passing small trains. The roads used for large rubber-wheeled trucks in a mine are often tens of thousands of meters long. The tire diameter of the rubber-wheeled trucks used underground is large, usually about 1 meter, and the chassis is about 30 centimeters above the ground. The load capacity is large, and the total weight of the truck and cargo can reach up to 60 tons. The truck is short and the cargo is high, and the ability to resist left and right shaking is poor.

[0003] This type of rubber-wheeled vehicle usually travels in the tunnels dug by the tunnel boring machine. Figure 1 As shown, the ground inside the tunnel is mostly composed of rocks, coal gangue, and crushed coal. The geological conditions are bumpy and uneven, and the level difference between the left and right sides is extremely large, with the maximum difference reaching 500 mm. Rubber-wheeled vehicles cannot pass at all, so the underground transportation department will use on-site mixing and pouring concrete to pave the road surface for vehicles. However, due to the uneven ground foundation of the tunnel, the hardness and softness are different, and there is water on both sides of the original road, the concrete poured under this working condition has the following problems:

[0004] First: short lifespan. Load-carrying vehicles do not pass for a long time, and the road surface is seriously damaged and needs to be repaired. Second: Due to the limitations of underground conditions, most concrete mixes need to be mixed on site manually, the working environment is poor, and the strength is high. Third, it takes more than 10 days to dry up to the use strength, which often delays the overall mining progress. It is not conducive to improving labor productivity and the economic benefits of the mine. Fourth: Most tunnels are used temporarily, and the cost of concrete laying is high. After the mining tunnel is used, the service life is generally 60 days. The concrete pavement and tunnel will be backfilled together and cannot be recycled, which is a huge waste.

[0005] There is no good solution to this problem. Small pieces of thick plastic or rubber sheets are used for paving. After testing, the mine found that this method can only be used to temporarily restore the damaged concrete road surface depressions and is not suitable for large-scale paving. Moreover, heavy-duty rubber-wheeled vehicles have a greater impact on relatively hard materials and often roll over and cause damage.

[0006] If a whole piece of steel plate is laid horizontally, not only will it be difficult to construct due to its large mass, but the part of the steel plate suspended from the ground will be deformed by rolling and will soon become as rugged and ineffective as the ground, and lose its reuse value. Summary of the invention

[0007] In order to overcome the above-mentioned shortcomings, the present invention provides a method for laying a road paving module used on a rugged foundation.

[0008] The technical solution adopted by the present invention to solve its technical problem is:

[0009] A road paving module used on a rugged foundation includes a pavement unit and a shoulder unit connected to the pavement unit on both sides. The pavement unit is provided with a plurality of transparent accommodating holes arranged in a matrix. The edge of the pavement unit is provided with a plurality of connecting grooves, the connecting grooves of adjacent pavement units correspond to each other, and connecting plates are provided in the relative connecting grooves to splice the adjacent pavement units together.

[0010] The shoulder unit and the pavement unit are an integrated structure, and the connecting groove is located on the pavement unit and is perpendicular to the two side edges of the shoulder unit.

[0011] The shoulder unit and the pavement unit are separate structures. The shoulder unit includes a shoulder and a pavement connection unit integrally connected to the shoulder. The pavement connection unit is provided with a plurality of accommodating holes. The three side edges of the pavement connection unit are provided with a plurality of connection grooves. The connection groove on the side opposite to the shoulder on the pavement connection unit corresponds to the connection groove on one side of the pavement unit, and they are spliced ​​to each other by inserting a connecting plate.

[0017] The road surface unit and the shoulder unit are made of rubber or plastic.

[0018] A method for laying a road paving module used on a rugged foundation comprises the following steps: laying water pipes according to the water flow on both sides of the road surface, if the water flow is small, the natural water flow in the roadbed gap can be selected, after the water pipes are laid, the entire rugged road surface is completely covered with large-grained gravel to form a roadbed plane and compacted, when laying the gravel, a number of roadbed flow-blocking modules are evenly distributed inside the roadbed; the shoulder unit and the road surface unit are connected with a connecting plate according to the width of the entire roadbed, and gravels of suitable sizes are selected and filled in the receiving holes and the weight-reducing holes, and the filled gravels are compacted after a flat road surface is formed; when the entire road is used, the road surface connecting plate is pulled out, the gravels inside the shoulder unit and the road surface unit are shaken off and recycled, and stored in a cool place for the convenience of reuse next time.

[0019] Due to the adoption of the above-mentioned technical solution, the present invention has the following advantages:

[0020] The present invention provides a method for laying a road paving module for use on a rugged foundation. The module is composed of various units, which can be specifically selected according to the construction site, and the construction is flexible.

[0033] The present invention can be explained in more detail by the following examples. The purpose of disclosing the present invention is to protect all changes and improvements within the scope of the present invention. The present invention is not limited to the following examples.

[0034] A road paving module for use on a rugged foundation described in conjunction with the accompanying drawings includes a pavement unit 2 and a shoulder unit 1 connected to the pavement unit 2 on both sides. The pavement unit 2 is provided with a plurality of transparent accommodating holes 6 arranged in a matrix, and the edge of the pavement unit 2 is provided with a plurality of connecting grooves 7. The connecting grooves 7 of adjacent pavement units 2 correspond to each other, and connecting plates 10 are provided in the relative connecting grooves 7 to splice the adjacent pavement units 2 together. The above is a module for paving roads, which is spliced ​​with other modules through the connecting grooves 7 and the connecting plates 10 therein to finally form the required paved road.

[0035] The first embodiment, such as Figure 2 As shown, the shoulder unit 1 and the pavement unit 2 are an integrated structure, and the shoulder unit 1 and the pavement unit 2 constitute a minimum unit module, which is spliced ​​with other modules through a connecting groove 7 on the pavement unit 2 that is perpendicular to the two side edges of the shoulder unit 1.

[0036] The second embodiment, such as Figure 3-7As shown, the shoulder unit 1 and the pavement unit 2 are split structures. The advantage of this structure over the first embodiment is that it is flexible to lay. The width of the required pavement unit 2 can be selected according to the width of the roadbed. It can be applied to roadbeds of any width without being specially customized according to the width of the roadbed. The shoulder unit 1 includes a shoulder 4 and a pavement connection unit 5 integrally connected to the shoulder 4. The pavement connection unit 5 is provided with a plurality of accommodating holes 6. The pavement connection unit 5 is provided with a plurality of connecting grooves 7 at the edges of the other three sides except the face where the shoulder 4 is located. The connecting grooves 7 on the side opposite to the shoulder 4 on the pavement connection unit 5 correspond to the connecting grooves 7 on one side of the pavement unit 2, and they are spliced ​​together by inserting the connecting plate 10, so that they can be spliced ​​into the road paving module described in the present invention. If splicing between modules is required, it is only necessary to make the connecting grooves 7 on the two corresponding sides of the pavement connection unit 5 correspond to the connecting grooves 7 of the pavement connection units 5 adjacent to the front and rear, and insert the connecting plate 10.

[0037] Furthermore, the pavement unit 2 can be one piece, or it can be split into several smaller units for easy transportation and installation.

[0038] The pavement unit 2 and the pavement connection unit 5 are provided with a plurality of transparent weight-reducing holes 8 , and the weight-reducing holes 8 are located between the gaps of the accommodating holes 6 .

[0039] A plurality of grooves 9 are provided at the bottom of the pavement unit 2 and the pavement connection unit 5 .

[0040] The cross section of the connecting plate 10 is bone-shaped, thick at both ends and thin in the middle. The cross sections of the two corresponding connecting grooves 7 are the same as the connecting plate 10 .

[0041] The pavement unit 2 and the shoulder unit 1 are made of rubber or plastic with certain elasticity and hardness, and may be embedded with metal or plastic plates to improve the overall rigidity.

[0042] Before paving, the present invention needs to be paved with stones on the rugged road. After the stones are leveled, the present invention is paved. Each unit is spliced ​​into a whole through the connecting groove 7 and the connecting plate 10. The height of the connecting plate 10 is not higher than the depth of the connecting groove 7. The specific thickness of each unit can be designed according to the specific conditions of the road surface and the weight of the load vehicle. After paving, fill the receiving hole 6 with stones and compact the filled stones. The aperture of the receiving hole 6 is preferably not less than 5 times the diameter of the stone. The smaller the stone is relative to the aperture of the receiving hole 6, the easier it is to compact it, the smaller the gap between the stones, and the better the use effect. The weight-reducing hole 8 is also filled with stones of suitable size. When a loaded rubber-wheeled vehicle passes through, the roadbed stones and the stones filled in the receiving hole 6 provide the overall support force of the vehicle. Since the material of the road surface unit 2 and the shoulder unit 1 is rubber or plastic, it has a certain elasticity and Hardness, so when the vehicle is driving on the paved road, the stones in the receiving holes 6 under the wheels are squeezed, but they will be restricted by the receiving holes 6. At the same time, the stones in the surrounding receiving holes 6 also have corresponding resistance to them, so the displacement of the stones in the squeezed receiving holes 6 is small, which is equivalent to locking the stones, which is beneficial to ensure the integrity of the entire road surface when the vehicle passes repeatedly. At the same time, a groove 9 is provided at the bottom of the pavement unit 2 and / or the pavement connection unit 5, preferably an arc-shaped groove, which is beneficial to the connection between the pavement unit 2 and the pavement connection unit 5 and the stones on the roadbed, increases the friction between the roadbed and the pavement unit 2 and the pavement connection unit 5, ensures that the entire module will not be displaced when the vehicle passes, ensures the integrity of the spliced ​​road surface, reduces the wear of the connecting plate 10 and the connecting groove 7, and extends the service life of the entire module.

[0043] A method for laying road paving modules used on a rugged foundation includes the following steps: laying water pipes according to the water flow on both sides of the road surface. If the water flow is small, the natural water flow can be used to utilize the gaps in the roadbed. After the water pipes are laid, large-grained stones are completely covered on the entire rugged road surface to form a roadbed plane and compacted. When laying the stones, a number of roadbed flow-blocking modules 3 are evenly distributed inside the roadbed. The roadbed flow-blocking modules are made of elastic materials with a certain hardness, such as rubber or plastic. The internal holes are used to retain roadbed stones. The outer stripes of the modules can increase the friction and cohesion of the stones around the modules to prevent the roadbed stones from being squeezed and flowing. The shoulder unit 1 and the road surface unit 2 are connected with a connecting plate 10 according to the width of the entire roadbed. The appropriate size is selected. The stones are filled in the receiving holes 6 and the weight-reducing holes 8, and the stones are compacted after forming a flat road surface. The stones on the entire road surface are trapped inside the receiving holes 6 of the road surface unit 2. The entire road surface is connected together by friction using the weight of the stones and the roadbed stones below. At the same time, the grooves 9 further increase the friction between the module and the roadbed, and the gripping ability is further enhanced. When a loaded rubber-wheeled vehicle passes, the stones on the entire road are trapped in the receiving holes 6, the roadbed flow-blocking module 3 and the rock walls on both sides, and the entire road loses fluidity. The stones provide the load-bearing capacity, ensuring the load-bearing capacity and long-term practicality of the road surface. When the entire road is used, the road surface connecting plate 10 is pulled out, and the stones inside the shoulder unit 1 and the road surface unit 2 are shaken off and recycled, and stored in a cool place for reuse next time. The roadbed stones and low-cost flow-blocking modules can be recycled by a small excavator or can be selected to be backfilled with the entire roadway without recycling.

[0044] The parts not described in detail in the above content are prior art, so they are not described in detail.
