Slab culvert sewage intercepting well

Abstract

The invention discloses a slab culvert sewage intercepting well, which comprises a slab culvert body and a sewage intercepting well, wherein the sewage intercepting well comprises a first sewage intercepting cavity which is communicated with a water inlet, and a second sewage intercepting cavity which is communicated with a river channel; a flap valve is arranged between the first sewage intercepting cavity and the second sewage intercepting cavity; an intercepting tube is communicated with the first sewage intercepting cavity; and a grating is arranged between the intercepting tube and the first sewage intercepting cavity through a grating guide groove. Through the slab culvert sewage intercepting well, primary rainwater and dry weather flow which are transported by a slab culvert are intercepted by the grating and then are collected and transported to a sewage plant for treatment, and the later superfluous rainwater during a rainstorm can be discharged into the river channel through the flap valve, so that pollution of the primary rainwater to the river channel is effectively reduced, and the river channel can receive water normally. The slab culvert sewage intercepting well is flexibly set, requires a small amount of equipment, has a stable flow, cannot be blocked and is convenient to operate and manage.

Description

technical field [0001] The invention relates to the technical field of drainage, in particular to a cover plate culvert sewage interception well. Background technique [0002] Due to the development of industrial economy and the discharge of waste water from people's daily life, the rivers of many cities are seriously polluted. Since most of the rivers have the functions of urban flood control and landscape, it is difficult to find a comprehensive solution that takes into account the interests of multiple parties when dealing with the problem of river sewage discharge. [0003] In order to prevent the river from being polluted, it is necessary to collect initial rainwater and sewage. The common technical means is to intercept the sewage before the initial rainwater and sewage are discharged into the river. However, because some urban sewers use cover plate culverts for sewage transfer, and the cover plate culverts are large in size, it is difficult to modify the interceptio...

AI Technical Summary

Problems solved by technology

The common technical method is to carry out sewage interception before the initial rainwater and sewage are discharged to the river. However, because some urban sewers use slab culverts for sewage transfer, and the slab culverts are large in size, it is difficult to modify the interception by normal methods, and overflows are prone to occur in rainy days. , causing the river to be seriously polluted
