Water drainage well for sponge city

Abstract

The invention discloses a water drainage well for a sponge city. The water drainage well comprises an outer well, a guide frame and a filtering box, wherein an inner well is arranged in the outer well; rainwater pipes penetrate through the surfaces of the inner well and the outer well; anti-overflow holes are formed in the surface of the inner well; a permeation well base is arranged under the outer well; a crushed stone layer is charged into a geotextile cloth; the guide frame is positioned in the inner well; a bearing shaft is fixedly connected with a coiling shaft at the inner side; a handle is arranged at the left side of the bearing shaft; a steel wire rope is wound at the outer side of the coiling shaft; the guide frame penetrates through the bottom part of the filtering box; a mounting base is arranged at the center of the bottom part of the inner surface of the filtering box. The water drainage well for the sponge city has the advantages that by arranging the outer well and theinner well, when excessive water is stored in the inner well, the water permeates into the permeation well base to be stored, so that the storage amount of the whole water drainage well is increased;by designing the coiling shaft and the steel wire rope, the filtering box can be lifted up, so that the garbage in the filtering box can be conveniently fetched out.

Description

technical field [0001] The invention relates to the technical field of sponge cities, in particular to a drainage well for sponge cities. Background technique [0002] Sponge city, sponge city means that the city can be like a sponge, with good elasticity in adapting to environmental changes and responding to natural disasters. When it rains, it absorbs, stores, infiltrates, and purifies water. Take advantage of it. The existing drainage wells have poor permeability in the construction of sponge cities, and during the flood season, due to the large flow, debris enters the drainage wells and settles in the drainage wells, resulting in blockage of the drainage wells and the occurrence of stench, which requires manual drainage The interior of the well is being repaired. Contents of the invention [0003] The purpose of the present invention is to provide a kind of drainage well for sponge city, to solve the problem that the existing drainage well in the construction of spon...
