Description

Technical Field

[0001] The present application relates to the field of drainage systems, and in particular to a sponge city road water supply and drainage structure. Background Art

[0002] In recent years, the concept of sponge city construction has gradually penetrated into urban construction. By taking water supply and drainage measures such as "infiltration, retention, storage, purification, use and discharge", rainwater is fully utilized, enabling cities to flexibly adapt to environmental changes and natural disasters.

[0003] In the existing related technologies, in order to store and reuse rainwater, it is necessary to use porous fiber cotton to build a water storage module. For example, utility model patent CN 217053706 U is an ecological porous fiber cotton for improving urban flood prevention capabilities. It buries a number of porous fiber cottons in the soil, and pipes connect the several porous fiber cottons to each other, and connect the several porous fiber cottons to the external municipal water supply and drainage system, so that the soil rainwater is absorbed, stored and discharged through the porous fiber cotton with good water absorption performance.

[0004] With regard to the above-mentioned related technologies, the water storage module constructed of porous fiber cotton is buried in the soil, and the porous fiber cotton is easily blocked by impurities, which affects the service life of the water storage module. Summary of the invention

[0005] In order to reduce the occurrence of blockage of the porous fiber quilt of the water storage module and thus ensure the service life of the water storage module, the present application provides a sponge city road water supply and drainage structure.

[0006] The sponge city road water supply and drainage structure provided in this application adopts the following technical solution:

[0007] A sponge city road water supply and drainage structure, comprising a water storage module and a filter frame, wherein the water storage module comprises a plurality of porous fiber cottons;

[0008] The filter frame is arranged around the water storage module, and is provided with a first filter tank and a second filter tank. The first filter tank is farther away from the water storage module than the second filter tank. The first filter tank is used to fill gravel, and the second filter tank is used to fill sand.

[0009] By adopting the above technical solution, the crushed stones in the first filter tank and the gravel in the second filter tank surround the water storage module, so that the rainwater in the soil needs to pass through the crushed stones and gravel in turn before entering the porous fiber cotton, and then the impurities in the rainwater are blocked by the crushed stones and gravel, thereby reducing the occurrence of the porous fiber cotton of the water storage module being blocked, ensuring the service life of the water storage module. In addition, after long-term use, by digging out the filter frame and lifting it as a whole, the crushed stones and gravel in the filter frame can be quickly cleaned, thereby facilitating the daily maintenance of the filter frame.

[0010] Optionally, the particle size of the crushed stone filled in the first filter tank is 2.0-2.5 mm, and the particle size of the gravel filled in the second filter tank is 0.5-1.0 mm.

[0011] By adopting the above technical solution, the crushed stones in the first filter tank and the gravel in the second filter tank can be ensured to filter the impurities in the rainwater.

[0012] Optionally, the height dimensions of the top of the first filter tank and the top of the second filter tank are both greater than the height dimension of the top of the water storage module.

[0013] By adopting the above technical solution, rainwater is not easy to bypass the gravel in the first filter tank and the gravel in the second filter tank and enter the porous fiber cotton, which is conducive to ensuring the effect of filtering impurities in the rainwater.

[0014] Optionally, the filter frame includes a steel frame body and a steel wire mesh, the steel wire mesh is installed on the steel frame body, and the first filter tank and the second filter tank are both surrounded by the steel frame body and the steel wire mesh.

[0015] By adopting the above technical solution, the steel wire mesh is lighter, which makes it easier for construction workers to lift the filter frame as a whole when maintenance is needed.

[0016] Optionally, the inner diameter of the mesh of the wire mesh is smaller than the particle size of the gravel filled in the first filter tank.

[0017] The adoption of the above technical solution is helpful to reduce the occurrence of gravel leaking out of the mesh of the wire mesh.

[0018] Optionally, the top of the water storage module is covered with a gravel layer and a crushed stone layer, and the gravel layer is farther away from the water storage module than the crushed stone layer.

[0019] By adopting the above technical solution, the gravel layer and crushed stone layer filter the rainwater that penetrates into the soil from the surface, so that the impurities in the rainwater are blocked by the crushed stone and gravel, thereby reducing the blockage of the porous fiber cotton blanket of the water storage module and ensuring the service life of the water storage module.

[0020] Optionally, the height dimensions of the top of the first filter tank and the top of the second filter tank are both greater than or equal to the height dimension of the top of the gravel layer.

[0021] By adopting the above technical solution, it is convenient for construction workers to lift the filter frame as a whole when it is necessary to maintain the filter frame, thereby reducing the need to dig up the gravel layer and the crushed stone layer.

[0022] Optionally, a gravel cushion layer is provided at the bottom of the water storage module, the width of the gravel cushion layer is greater than the width of the water storage module, and the thickness of the gravel cushion layer is greater than 100 mm.

[0023] By adopting the above technical solution, the gravel cushion layer makes it easier for the porous fiber cotton to evenly transfer the load to the soil after storing a large amount of rainwater.

[0024] In summary, the present application includes at least one of the following beneficial technical effects:

[0025] 1. The crushed stones in the first filter tank and the gravel in the second filter tank surround the water storage module, so that the rainwater in the soil needs to pass through the crushed stones and gravel in turn before entering the porous fiber cotton, so that the impurities in the rainwater are blocked by the crushed stones and gravel, thereby reducing the occurrence of the porous fiber cotton of the water storage module being blocked, ensuring the service life of the water storage module. In addition, after long-term use, by digging out the filter frame and lifting it as a whole, the crushed stones and gravel in the filter frame can be quickly cleaned, which is convenient for daily maintenance of the filter frame.
