Description

Technical Field

[0002] The reinforcement structure for the base layer of an urban road surface refers to adopting specific technologies and materials to reinforce the base layer of the urban road surface, so as to improve the bearing capacity, durability and stability of the road surface. This work is usually carried out to extend the service life of the road surface, reduce maintenance costs and improve traffic safety.

[0003] In the prior art, such as Chinese Patent No.: CN214831638U, this utility model discloses a reinforcement structure for the edge of a roadbed in highway construction, including a roadbed. An edge reinforcement structure is provided at the right end of the roadbed. A drainage ditch is provided at the right end of the edge reinforcement structure. A planting soil layer is provided on the top of the edge reinforcement structure. A geotextile is provided on the top of the planting soil layer. A circular groove is formed inside the planting soil layer. An annular skeleton is embedded in the circular groove. A planting net is provided inside the annular skeleton. A water flow groove is formed inside the planting soil layer. The structure of this device is stable. The rainwater on the road surface flows into the drain holes through the drainage grooves, and then flows into the drainage ditch, so that the rainwater on the road surface is discharged in time, avoiding the infiltration of rainwater along the roadbed, thus preventing the phenomenon that the roadbed slope is washed, improving the safety and stability of the roadbed slope. At the same time, the water flow groove can help the roadbed slope drain water and reduce the pressure on the roadbed slope.

[0004] Although the above solution has the advantages of improving the safety and stability of the roadbed slope as described above, and at the same time the water flow groove can help the roadbed slope drain water and reduce the pressure on the roadbed slope, when the above solution is actually used, since its reinforcement structure is designed to be set as a whole section on the side of the base layer and not in a segmented design, once a certain section of the reinforcement structure is damaged, the entire section of the reinforcement structure needs to be replaced or repaired. Such a practice may lead to an increase in the time and effort required for maintenance work, not only greatly increasing the labor intensity of the staff, but also causing waste.

Specific implementation manner

[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0031] Example 1, please refer to Figures 1-4 , the present utility model provides a technical solution: a reinforcing structure for the base layer of an urban road surface, including a base layer body 1, protective plates 101 are arranged on both sides of the base layer body 1, support columns 102 are arranged on the outer surfaces of both sides of the two protective plates 101, ground nails 103 are arranged inside the two protective plates 101, connectors 104 are arranged on the outer sides of the two protective plates 101, screw rods 105 are arranged inside the two connectors 104, cranks 106 are arranged on the tops of the two screw rods 105, connection blocks 107 are arranged at the left ends of the outer sides of the two protective plates 101, thread grooves 108 are opened inside the two connection blocks 107, the two thread grooves 108 correspond to the screw rods 105, positioning plates 110 are arranged on the right sides of the two protective plates 101, positioning grooves 111 are opened on the left sides of the two protective plates 101, a plurality of bolts 109 are arranged inside the two protective plates 101, the outer surfaces of the plurality of bolts 109 are arranged inside the base layer body 1, a geotechnical layer 2 is arranged on the bottom side of the inner wall of the base layer body 1, and the material of the geotechnical layer 2 is a geogrid.

[0032] In this embodiment, the user first places the guard plate 101 on the outside of the base body 1 and makes it fit the outer surface of the base body 1. Then, the bolt 109 is rotated to embed the bolt 109 into the interior of the base body 1 and inside the surface layer 203. After that, the ground nail 103 is hammered downward to embed the ground nail 103 into the ground, thereby fixing the guard plate 101 to the outside of the base body 1 to reinforce the base body 1. Then, the support column 102 is picked up, the inner side of the support column 102 is placed on the outside of the guard plate 101, and the support column 102 is fixed to the guard plate 101 by welding, thereby reinforcing the guard plate 101. When it is necessary to splice and lay the reinforcement structure, another guard plate 101 can be picked up and placed on the right side of the first guard plate 101, and the second guard plate 101 is pushed to the left, so that the positioning plate 110 is embedded into the positioning groove 111, and at the same time, the connecting block 107 is embedded into the connecting member 104. Then, the crank 106 is rotated forward to drive the screw 105 to rotate, so that the screw 105 can move downward while rotating, and then the screw 105 is embedded into the thread groove 108 to connect the two guard plates 101. When one guard plate 101 is damaged and needs to be disassembled, the crank 106 can be rotated in reverse to drive the screw 105 to disengage from the thread groove 108, and then the guard plate 101 is pulled to the right to make the positioning plate 110 disengage from the positioning groove 111, thereby completing the disassembly. Moreover, through the settings of the guard plate 101 and the connecting member 104 and other structures, not only does the entire reinforcement structure have high stability and reliability after installation, which can effectively reinforce the base body 1 and improve the stability and durability of the road surface, but also through the design of the positioning plate 110, the connecting member 104 and the screw 105, the reinforcement structure has a certain degree of flexibility and dismountability. When splicing and laying are required, a new guard plate 101 can be quickly connected to the existing structure to meet the needs of extending or repairing the road surface, and this structural design makes the entire reinforcement structure relatively easy to repair and replace.

[0033] Embodiment 2, as Figures 1-4 shown, a base layer 201 is provided on the top of the geotechnical layer 2. The material of the base layer 201 is soil. A base course 202 is provided on the top of the base layer 201. The material of the base course 202 is crushed stones. A surface layer 203 is provided on the top of the base course 202. The material of the surface layer 203 is concrete. A plurality of reinforcing bars 204 are provided inside the surface layer 203. The material of the reinforcing bars 204 is steel. A waterproof layer 205 is provided on the top of the surface layer 203. The material of the waterproof layer 205 is asphalt waterproof coating.

[0034] In this embodiment, the personnel can first lay the geotechnical layer 2 made of geogrid on the top of the flat road surface, and lay the base layer 201 made of soil on the top of the geotechnical layer 2. Then, lay gravel on the top of the geotechnical layer 2 to form the base layer 202, and lay concrete on the top of the base layer 202 to form the surface layer 203. Embed the reinforcing bars 204 made of steel into the interior of the surface layer 203 to reinforce the base body 1 from the inside. After the surface layer 203 dries, spray asphalt waterproof coating on the surface layer 203 to form the waterproof layer 205, thus completing the construction of the base body 1. Through the laying of multiple layers of structures, the traffic load can be effectively dispersed and borne, improving the bearing capacity and stability of the road surface. At the same time, the combination of the geotechnical layer 2, the base layer 201 and the base layer 202 can reduce the deformation and settlement of the road surface, extending the service life of the road surface. The combination of the surface layer 203 and the internal reinforcing bars 204 can increase the durability of the road surface, reduce cracks and damage, and lower the maintenance cost, thus reinforcing the base body 1 from the inside. The waterproof layer 205 can effectively prevent water penetration, protect the road surface structure, and extend the service life.

[0035] Working principle: When in use, first place the guard plate 101 on the outside of the base body 1 and make it fit the outer surface of the base body 1. Then rotate the bolt 109 so that the bolt 109 is embedded inside the base body 1 and located inside the surface layer 203. After that, hammer the ground nail 103 downward so that the ground nail 103 is embedded inside the ground, thereby fixing the guard plate 101 to the outside of the base body 1 to reinforce the base body 1. Then pick up the support column 102, place the inner side of the support column 102 on the outside of the guard plate 101, and fix the support column 102 to the guard plate 101 by welding, thereby reinforcing the guard plate 101. When it is necessary to splice and lay the reinforcement structure, another guard plate 101 can be picked up and placed on the right side of the first guard plate 101, and the second guard plate 101 is pushed to the left so that the positioning plate 110 is embedded inside the positioning groove 111, and at the same time the connecting block 107 is embedded inside the connecting member 104. Then rotate the crank 106 clockwise to drive the screw 105 to rotate, so that the screw 105 can move downward while rotating, and then the screw 105 is embedded inside the thread groove 108 to connect the two guard plates 101. When one guard plate 101 is damaged and needs to be disassembled, the crank 106 can be rotated counterclockwise to drive the screw 105 to disengage from the thread groove 108, and then the guard plate 101 is pulled to the right so that the positioning plate 110 disengages from the positioning groove 111, thereby completing the disassembly. And through the settings of the guard plate 101 and the connecting member 104 and other structures, not only does the entire reinforcement structure have high stability and reliability after installation, which can effectively reinforce the base body 1 and improve the stability and durability of the road surface, but also through the design of the positioning plate 110, the connecting member 104 and the screw 105, the reinforcement structure has a certain degree of flexibility and dismountability. When it is necessary to splice and lay, a new guard plate 101 can be quickly connected to the existing structure to meet the needs of extending or repairing the road surface, and this structural design makes the entire reinforcement structure relatively easy to repair and replace.During use, personnel can first lay the geotechnical layer 2 made of geogrid on the top of the leveled road surface, and lay the base layer 201 made of soil on the top of the geotechnical layer 2. Then, lay gravel on the top of the geotechnical layer 2 to form the base layer 202. Next, lay concrete on the top of the base layer 202 to form the surface layer 203, and embed the reinforcing bars 204 made of steel into the interior of the surface layer 203 to reinforce the base body 1 from the inside. After the surface layer 203 dries, spray asphalt waterproof coating on the surface layer 203 to form the waterproof layer 205, thus completing the construction of the base body 1. Through the laying of multiple layers, traffic loads can be effectively dispersed and borne, improving the bearing capacity and stability of the road surface. At the same time, the combination of the geotechnical layer 2, the base layer 201, and the base layer 202 can reduce the deformation and settlement of the road surface, extending the service life of the road surface. The combination of the surface layer 203 and the internal reinforcing bars 204 can increase the durability of the road surface, reduce cracks and damages, and lower the maintenance cost, thereby reinforcing the base body 1 from the inside. The waterproof layer 205 can effectively prevent water penetration, protect the road surface structure, and extend the service life.

[0036] The above is only the preferred embodiment of the present invention, and it does not limit the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields.
