Description

Technical Field

[0001] This utility model relates to the field of roadbed reinforcement technology, specifically a roadbed anti-erosion reinforcement structure. Background Technology

[0002] The roadbed is the foundation of a highway pavement. It is an earthwork structure formed by excavation or filling. The main function of the roadbed is to provide the necessary conditions for pavement laying and traffic operation, and to bear the static and dynamic loads of locomotives, vehicles, or road surface and traffic loads, while transferring and diffusing the loads deep into the foundation.

[0003] In existing technologies, the roadbed, as the supporting structure of the road, is usually composed of loose materials such as soil and rock. Its stability is affected by a variety of factors. Among them, water erosion is one of the important causes of roadbed slope collapse. When water flows over the roadbed slope, it carries away the soil particles on the slope surface, gradually forming gullies, which seriously damages the overall structure of the slope and leads to slope collapse. In severe cases, it can even affect the safe passage of the road. Therefore, a roadbed erosion prevention and reinforcement structure is needed to solve this problem. Utility Model Content

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0026] This utility model provides a roadbed erosion prevention and reinforcement structure. Please refer to [link / reference]. Figures 1-4 The system includes a roadbed body 100 and reinforcing blocks 200. A pavement layer 110 is installed on top of the roadbed body 100. Drainage frames 120 are symmetrically installed on both sides of the pavement layer 110, and drainage channels 130 are formed within the drainage frames 120. Several reinforcing blocks 200 are fixedly installed on both sides of the roadbed body 100, and are installed at an angle. A drainage channel 210 is formed on the top of each reinforcing block 200, and several planting troughs 220 are formed within the drainage channel 210. Positioning holes 230 are formed on the sidewalls of each reinforcing block 200, and anchor bolts 240 are embedded within the positioning holes 230. Specifically, the roadbed body 100 provides support to the pavement layer 110, ensuring the stability of the road and driving safety. The drainage frames 120 guide and support water flow, and the drainage channels 130 receive water. It guides the water flow from the pavement layer 110 and safely discharges it outside the roadbed, thereby protecting the roadbed from water scouring and erosion. By stacking several reinforcing blocks 200, it is easy to add a sloping stepped reinforcement structure on both sides of the main roadbed 100. The stepped reinforcing blocks 200 effectively protect the roadbed. The drainage channels 210 on each reinforcing block 200 effectively divert rainwater, thereby reducing the direct scouring effect of water flow on the roadbed. The planting troughs 220 facilitate the planting of green plants, strengthen the protection of the reinforcing blocks 200, and extend their service life. Anchor rods 240 are inserted into the roadbed body through the positioning holes 230. The anchor rods 240 facilitate the firm installation of the reinforcing blocks 200 on both sides of the main roadbed 100, and facilitate the tight connection between the reinforcing blocks 200 and the main roadbed 100.

[0027] The two ends of the diversion channel 210 are equipped with filter screens 400, which are fixedly connected to the inner wall of the reinforcing block 200. Specifically, the filter screens 400 can effectively block soil particles carried in the water flow, reducing the possibility of soil being carried away by the water flow from the diversion channel 210.

[0028] A waterproof layer is provided on the top of the roadbed body 100. The waterproof layer is located between the pavement layer 110 and the roadbed body 100. Specifically, the waterproof layer helps to increase the waterproof effect of the top of the roadbed body 100 and reduce the infiltration of rainwater into the roadbed body 100.

[0029] Several reinforcing blocks 200 form a stepped structure, which facilitates increasing the erosion resistance of the main roadbed 100.

[0030] One end of the anchor rod 240 is embedded in the roadbed body 100 through the positioning hole 230. The reinforcing block 200 is fixedly connected to the roadbed body 100 through the anchor rod 240. Specifically, this facilitates the fixed connection between the reinforcing block 200 and the roadbed body 100, and improves the stability of the installation.

[0031] The sidewalls of the reinforcing block 200 are provided with anti-slip textures. Specifically, the anti-slip textures make it difficult for the reinforcing blocks 200 to slide when stacked together.

[0032] Combination Figures 1-4 This embodiment of a highway subgrade erosion protection and reinforcement structure is used as follows: The subgrade body 100 provides support to the pavement layer 110, ensuring highway stability and driving safety. A diversion frame 120 guides and supports water flow, while a drainage ditch 130 receives and guides water from the pavement layer 110, safely draining it outside the subgrade, thus protecting it from erosion. Several reinforcement blocks 200 are stacked on both sides of the subgrade body 100 to form a sloping stepped reinforcement structure. The stepped reinforcement blocks 200 effectively... The roadbed is protected to prevent rainwater from directly eroding it and to improve its erosion resistance. Rainwater is effectively diverted through the drainage channels 210 on each reinforcement block 200, thereby reducing the direct erosion effect of water flow on the roadbed. Green plants are planted through planting troughs 220 to strengthen the protection of the reinforcement blocks 200 and extend their service life. Anchor bolts 240 are inserted into the roadbed body through positioning holes 230 and the reinforcement blocks 200 are firmly installed on both sides of the roadbed body 100 through the anchor bolts 240, so that the reinforcement blocks 200 are tightly connected to the roadbed body 100.

[0033] Figures 3-4 The diagram shown is a structural schematic of the second embodiment of the highway subgrade erosion prevention and reinforcement structure of this utility model. Please refer to [link / reference]. Figures 3-4 Unlike the above-described implementation, the inner walls of the two drainage racks 120 are provided with grilles 300. The grilles 300 are inclined and the two grilles 300 are symmetrically arranged. Specifically, the grilles 300 facilitate the filtration of impurities in the rainwater to prevent clogging of the drainage channel 130. At the same time, the inclined design of the grilles 300 can prevent impurities from accumulating and clogging on the grilles 300, which is conducive to the smooth and stable drainage system.

[0034] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way.
