[0021] The sponge city seepage drainage device, as shown in Figure 1 , Figure 2 and Figure 3 , comprises a ground seepage drainage structure 2, a water storage pool 1 located below the ground seepage drainage structure 2 and a vertical shaft located beside the water storage pool 1; the water storage pool 1 is provided with a high-pressure steel pipe 3 for conveying high-pressure water, the high-pressure steel pipe 3 is fixed to the inner wall of the water storage pool 1 in the transverse direction of the water storage pool 1; a plurality of groups of high-pressure spray heads 4 are arranged in the axial direction of the high-pressure steel pipe 3; the high-pressure steel pipe 3 is firm and durable, is used for connecting the high-pressure spray heads 4 and conveying high-pressure water for the high-pressure spray heads 4. The high-pressure spray head 4 needs to be able to withstand the impact of high-pressure water flow, to ensure that the water column sprayed is strong and powerful, and the coverage is extensive. The high-pressure spray head 4 sprays water to preliminarily clean the inner wall of the water storage pool 1. The technology of conveying high-pressure water through the high-pressure steel pipe 3 is prior art, the water inlet of the high-pressure steel pipe 3 is not shown in the drawing, the high-pressure water in the high-pressure steel pipe 3 can be a water source outside the water storage pool 1, or the water in the water storage pool 1 can be output through the water outlet pipe 11, pressurized through a pressurizing device and then supplied to the high-pressure steel pipe 3.

[0022] The acoustic wave device 5 is fixedly connected to the inner wall of the water storage pool 1, the acoustic wave device 5 can emit high-frequency sound waves to generate vibration in water, the high-frequency vibration of the acoustic wave device 5 acts on the water storage pool 1 to clean the residual dirt in the water storage pool 1.

[0023] The physical scouring of the high-pressure water flow and the acoustic wave vibration cooperate to clean, realize dead angle cleaning and improve the cleaning effect.

[0024] The shaft is a treatment well 8, the bottom of the treatment well 8 is provided with a sewage bin 9, the outer side wall of the sewage bin 9 is in sliding fit with the inner side wall of the treatment well 8 along the axial direction of the treatment well 8;

[0025] The side wall of the reservoir 1 and the treatment well 8 are provided with a sewage discharge channel 6, the sewage discharge inlet of the sewage discharge channel 6 penetrates the inner wall of the reservoir 1, the sewage discharge outlet is centered on the sewage bin 9, and an automatic sewage valve 7 for controlling the opening and closing of the sewage discharge channel 6 is arranged.

[0026] After the reservoir 1 is cleaned, the sewage valve 7 is opened, the sewage is discharged from the sewage discharge inlet and temporarily stored in the sewage bin 9 at the bottom of the treatment well 8, and when the treatment date is reached, the sewage bin 9 is pulled out of the treatment well 8 for regular cleaning. The structure can automatically clean the reservoir 1, ensure the water quality, and avoid the risk of pipe blockage by dirt after long-term use.

[0027] During the normal water storage period after the reservoir 1 is cleaned, the sewage valve 7 is closed, and when the water in the reservoir 1 needs to be used, the water outlet valve 12 is opened, and the water is output through the water outlet pipe 11.

[0028] If only one sound wave device 5 is arranged, the water at a position far from the sound wave device 5 is vibrated at low intensity, which is not conducive to uniform cleaning intensity. In order to make the sound wave effect as uniform as possible, preferably, sound wave devices 5 are arranged on the front and rear side walls of the reservoir 1 in the longitudinal direction, and the sound wave devices 5 on the front and rear side walls are arranged oppositely.

[0029] Preferably, the well mouth of the treatment well 8 is provided with a well cover, the well cover includes a semicircular fixed cover and a semicircular movable cover 14, the fixed cover covers part of the well mouth, and the movable cover 14 can be moved to cover another part of the well mouth, and the well mouth is completely blocked by the movable cover 14 and the fixed cover.

[0030] In the embodiment, the well mouth of the treatment well 8 is closed by a well cover, which isolates foreign matters in the outside from the treatment well 8 when the well cover covers the well mouth of the treatment well 8. The fixed cover covers part of the well mouth, which does not mean that the fixed cover cannot be detached from the well mouth, but it may not be convenient to move, such as heavy weight, etc. In addition to blocking part of the well mouth, another important function is to connect with the sewage bin 9. The fixed cover and the movable cover 14 are both semicircular in structure, which can ensure sufficient opening for cleaning the sediments in the sewage bin 9 pulled up, and also can ensure sufficient stress area, and the well cover ensures stability.

[0034] Currently, the surface infiltration structure 2 of sponge city infiltration and drainage devices typically includes a soil layer, a gravel layer, and a permeable layer. Rainwater enters the storage tank through the gravel layer and the permeable layer, thus playing a role in infiltration and water storage. However, its drainage path is limited to the gravel layer and the permeable layer to the storage tank, resulting in a single drainage path. During heavy rainfall, there is a risk of the storage tank reaching its water storage limit, leading to urban flooding. To avoid this problem, in this embodiment, as... Figure 4 As shown, the ground drainage structure 2 includes a permeable layer 201, a sand and gravel layer 205, and a road surface layer 206 from bottom to top. The top surface of the permeable layer 201 is a wavy undulating surface, including a protruding part that is narrow at the top and wide at the bottom and a concave part that is wide at the top and narrow at the bottom. The transition surface between the protruding part and the concave part is a guide surface 202. A permeable pipe 203 for guiding rainwater to be discharged outside the water storage tank 1 is buried in the concave part. In this embodiment, rainwater enters the lower layer through the drainage gaps of the pavement layer 206, preventing slippery surfaces and flooding. The lower layer adjacent to the pavement layer 206 is a gravel layer 205, which provides stable support for the pavement layer 206. The gravel layer 205 is composed of gravel with gaps between the gravel and sand, allowing rainwater to drain through these gaps to the infiltration layer 201. The infiltration layer 201 filters the rainwater, and its top guide surface 202 guides the water flow to the desired location, preventing the water from flowing randomly in the surrounding area and facilitating the full collection and utilization of rainwater.

[0035] The flow guide surface 202 guides the water flow to make the water flow more easily flow to the recess through the flow guide surface 202, the recess is provided with the permeation pipe 203, through the interception of the permeation pipe 203, the water flow permeates into the permeation pipe 203, is first discharged through the permeation pipe 203, and is used for irrigating the green belt when being discharged into the green belt.When heavy rain, the pressure increases, the water from the sand layer 205 is partially directly entered into the bottom water storage tank 1 to store water, and partially is shunted through the permeation pipe 203, can be discharged to a river, and also can be discharged to a water collecting tank outside the water storage tank 1 and other water storage systems, the rainwater is shunted through the double paths, the seepage and drainage efficiency is improved, different rainfall intensities can be adapted, rainwater hazards can be effectively prevented, urban safety can be enhanced, resource utilization can be improved, and seepage and drainage demands can be met.

[0036] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the utility model, the scope of the utility model is defined by the appended claims and their equivalents.
