[0004] When a vehicle drives on the road, the road will vibrate slightly, and over a long period of time, the place where the pipeline is laid in the road is prone to damage, and even collapse. SUMMARY

[0005] In order to improve the service life of the road, the present application provides a sponge type road paving structure.

[0006] The sponge type road paving structure provided by the present application adopts the following technical scheme:

[0008] Through the above technical scheme, when rainwater falls on the road, it enters the water storage tank after passing through the water permeable layer, the filter layer and the drainage layer, and can be collected and stored. In dry weather, the rainwater can be used to supplement the road to prevent the road from cracking, and the rainwater can be used twice to play an environmental protection role. When the rainfall is large and the water in the water storage tank is too much, the water is discharged to other places through the drainage pipe to avoid too much water in the water storage tank. The filter layer can filter impurities in the rainwater. The pressure bearing plate is located above the base layer and covers the water storage tank to protect the drainage pipe. The pressure bearing plate is arched, has high strength and stability, and when a vehicle drives above the road, the force generated by the vehicle is transmitted to the pressure bearing plate. The external load of the pressure bearing plate is evenly distributed to the entire structure, the force acting on the pressure bearing plate is reduced, the pressure bearing plate is not easy to vibrate, the service life of the pressure bearing plate is improved, and the road surface above the pressure bearing plate is not easy to be damaged.

[0009] Optionally, the support structure comprises a support strip arranged below the pressure bearing plate, a support rod is arranged below the support strip, and one end of the support rod away from the support strip is arranged on the bottom wall of the water storage tank.

[0010] By adopting the above technical scheme, the support strip supports the pressure bearing plate, shares the force received by the pressure bearing plate, and transmits the force to the base layer through the support rod.

[0011] Optionally, a positioning strip extending along the length direction of the pressure bearing plate is arranged below the pressure bearing plate, and a positioning groove into which the positioning strip is inserted is arranged above the support strip.

[0014] By adopting the above technical scheme, when the reinforcing strip abuts against the support strip, the movement of the reinforcing strip toward the support strip is limited, which has a limiting effect, and the reinforcing strip can improve the strength and pressure bearing capacity of the pressure bearing plate.

[0015] Optionally, a fixing groove is arranged on the base layer, the fixing groove is located on one side of the water storage tank, a pressure bearing piece is arranged on the pressure bearing plate, the pressure bearing piece comprises a fixing plate arranged on the pressure bearing plate, the fixing plate is arc-shaped, the fixing plate extends toward the fixing groove, the fixing plate is inserted into the fixing groove, a water guide channel is arranged at the end of the fixing plate, the water guide channel extends along the circumferential direction of the fixing plate, and a water inlet hole in communication with the water guide channel is arranged on the pressure bearing plate.

[0016] By adopting the above technical scheme, when the rainfall is large and the water in the sponge road is higher than the highest point of the water guide channel, the water in the fixing groove enters the water storage tank through the water guide channel, so that some impurities in the fixing groove can be prevented from entering the water storage tank, and the purity of the water in the water storage tank is improved.

[0017] Optionally, a locking structure connecting the pressure bearing plate and the fixing plate is arranged between the pressure bearing plate and the fixing plate, a mounting surface in a planar shape is arranged on the pressure bearing plate, the locking structure comprises an insertion block arranged at one end of the fixing plate toward the pressure bearing plate, the insertion block extends in the vertical direction, and an insertion groove for the insertion block is arranged on the mounting surface.

[0018] By adopting the above technical solution, the force on the fixing plate can be distributed to the pressure plate by the insert block, making the fixing plate less susceptible to damage from pressure; the insert block can be inserted into the slot to position the fixing plate, making the fixing plate and the pressure plate fit more stably.

[0019] Optionally, the width of the insert gradually increases in a direction away from the axis of the fixing plate.

[0020] By adopting the above technical solution, the insert block is inserted into the slot, making it impossible for the fixing plate to separate from the pressure plate in the horizontal direction.

[0021] Optionally, the end face of the insert block away from the axis of the fixed plate is provided with an operating groove, the operating groove is connected to the water guiding channel, and the locking structure further includes an operating tube slidably disposed in the operating groove, the water inlet hole is connected to the slot, and the operating tube is inserted into the water inlet hole.

[0022] By adopting the above technical solution, the operating pipe is inserted into the water inlet hole, allowing water in the water guide channel to enter the water storage tank through the operating pipe, making it less likely for water to leak from between the pressure plate and the fixed plate.

[0023] Optionally, a fixing column is fixedly connected to the bottom wall of the fixing groove and / or the base layer, and one end of the fixing column is connected to the bottom of the fixing plate.

[0025] Optionally, a drain hole is provided on the outer circumferential surface of the drain pipe.

[0026] By adopting the above technical solution, the water in the water storage tank can enter the drain pipe through the drain hole, and then the water can be recycled or discharged into the naturally formed waterway through the drain pipe.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. Rainwater falls onto the road and passes through a permeable layer, a filter layer, and a drainage layer before entering a water storage tank. This tank collects and stores rainwater, replenishing the road surface during dry weather to prevent cracking and allowing for secondary use, thus contributing to environmental protection. When heavy rainfall causes excessive water in the tank, the water is drained away through drainage pipes to prevent overwatering. The filter layer removes impurities from the rainwater. The pressure plate, located above the base layer and covering the water storage tank, protects the drainage pipes. The arched design of the pressure plate provides high strength and stability. When vehicles drive over it, the force is transferred to the pressure plate, evenly distributing the external load across the entire structure. This reduces the force on the pressure plate, preventing it from swaying, extending its lifespan, and minimizing damage to the road surface above it.

[0029] 2. A fixed plate and a water guiding channel are installed. When the water level in the drainage layer is higher than that in the fixed plate, the water enters the water storage tank through the water guiding channel for further water storage, while also reducing the entry of foreign objects into the water storage tank.
