Urban flood-control drainage well water guide and pollutant blocking apparatus and method

Abstract

The invention discloses an urban flood-control drainage well water guide and pollutant blocking apparatus and method. The urban flood-control drainage well water guide and pollutant blocking apparatus comprises a pollutant blocking structure, a water guide structure, an air guide rod and a fixed ring; the pollutant blocking structure comprises a pollutant blocking net, a slag collection pool and an air guide rod; the pollutant blocking net is of an annular shape and of a stainless steel netted structure and has certain flexibility; the slag collection pool is of a bowl shape with interior recessed and of a stainless steel netted structure; an outer ring of the slag collection pool is connected with an inner ring of the pollutant blocking net by virtue of a hinge; the air guide rod is a hollow stainless steel pipe and penetrates through the center of the slag collection pool; and the urban flood-control drainage well water guide and pollutant blocking apparatus can rapidly guide the discharge of the accumulated rainy water, pollutants are automatically collected; and meanwhile, convenience in disassembling, installation and application can be realized, and a purpose of effectively guiding the water and blocking pollutants can be realized.

Description

technical field [0001] The invention relates to the field of flood control and drainage, in particular to a water guide and sewage barrier device for urban flood control and drainage wells. Background technique [0002] The existing urban flood drainage design standards and related specifications are relatively old. Under the new situation of accelerated urbanization in China and the increase in the frequency of disastrous weather such as super heavy rains, the requirements for the construction and management of drainage facilities and the guarantee of urban operation safety Incompatible; every year in the rainy season, a large number of cities experience flooding and poor drainage, which have a great impact on people's lives and transportation. Road drainage and rainwater wells have become bottlenecks for smooth flood discharge; the lower part of existing rainwater wells is connected to drainage pipes, and there are seepage pipes extending downward at the bottom, which can ...

Problems solved by technology

[0003] However, in areas with a large amount of water, usually low-lying, the rainwater carries a large amount of urban garbage and floating pollutants. In the traditional drainage process, the garbage and pollutants accumulate and block the rainwater wellhead or the protective cover (basket) at the mouth of the well , resulting in poor drainage and difficulty in cleaning up garbage and pollutants; at the same time, a large amount of rainwater leaked down, causing water sealing, resulting in poor drainage; in addition, during the drainage process, common manhole covers were opened, under the cover of sewage, causing hidden dangers to pedestrians
