Self-adjusting seepage and drainage well for sponge city construction

Abstract

The invention belongs to the field of sponge city construction, and particularly relates to a self-adjusting seepage and drainage well for sponge city construction. The self-adjusting seepage and drainage well comprises a well body arranged underground in a buried mode and a well lid arranged on the well body, wherein a sewage drainage pipe and an underground water seepage pipe communicate with two sides of the well body correspondingly, and the horizontal position of the sewage drainage pipe is higher than that of the underground water seepage pipe; a water dividing plate is connected to theinner side wall of the well body in a sealed and sliding mode, a plurality of drainage holes formed in an annular array are formed in the well lid in a penetrating mode, a transparent daylighting panel is arranged in the center of the well lid in an embedded mode, and an elastic plate is fixed to the bottom of the well lid; and the section of the elastic plate is arranged in a downwards-concave arc shape, and a sealing cavity is formed by the elastic plate and the lower surface of the well lid. According to the self-adjusting seepage and drainage well for sponge city construction, the drainagemode of the seepage and drainage well can be adjusted according to different periods of urban rainfall, so that pollution of sewage to underground water is avoided, the rainwater drainage efficiencyof the seepage and drainage well is guaranteed, and good accumulation, seepage and purification functions are achieved.

Description

technical field [0001] The invention belongs to the field of sponge city construction, and in particular relates to a self-regulating seepage drainage well for sponge city construction. Background technique [0002] Sponge city is a new generation of urban rain and flood management concept. Under the premise of ensuring the safety of urban drainage and waterlogging, the accumulation, infiltration and purification of rainwater in the urban area shall be realized as much as possible, so as to promote the utilization of rainwater resources and the protection of the ecological environment, effectively alleviating the The problem of deteriorating environment and shortage of water resources should maximize the role of the city itself. The seepage and drainage wells in the sponge city play a key role in the infiltration and discharge of urban rainfall. [0003] Most of the traditional seepage drainage wells have simple structures and single functions. When it rains in cities, most ...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a self-regulating seepage and drainage well for sponge city construction that can improve the utilization rate of rainwater and speed up the discharge of rainwater in view of the problem that the above-mentioned seepage and drainage wells are difficult to store, infiltrate and purify rainwater.
