Inspection well capable of preventing rainwater and sewage from flowing backwards

Abstract

The invention relates to the technical field of building water supply and drainage systems, in particular to an inspection well facility capable of preventing rainwater and sewage from flowing backwards. The inspection well is mainly characterized in that the drainage of rainwater and sewage in industrial and civil building parks is conducted in a one-way mode and is reversely cut off, namely, the drainage in the industrial and civil building parks such as residences, business, offices, commercial complexes and plants is conducted in a one-way mode under the gravity flow or natural state of the rainwater and sewage in the parks, and the municipal rainwater and sewage are prevented from flowing backwards to the parks. According to the invention, the problem of serious water accumulation or waterlogging of the industrial and civil building parks such as the residences,the business, the offices, the commercial complexes and the plants due to backward flowing of the municipal rainwater and sewage into the parks due to too shallow burying of municipal rainwater and sewage pipelines or too large municipal rainwater and sewage quantity in the urban construction process is fundamentally solved.

Description

technical field [0001] The invention relates to the technical field of building water supply and drainage systems, in particular to a rain and sewage anti-backflow inspection well facility. Background technique [0002] With the development of the social economy, the industrial and civil construction industries have also developed vigorously. Therefore, the smooth discharge of rainwater and sewage inside the industrial and civil construction parks has played a vital role in the quality and comfort of the park. Due to recent years Climate uncertainty and the hysteresis and backwardness of the supporting construction of the municipal pipe network, the stability and reliability of the drainage of the construction park are increasingly demanding. Contents of the invention [0003] The purpose of the present invention is to overcome the problems existing in the prior art, and provide a facility based on the anti-backflow inspection well, which can fundamentally solve the proble...

Problems solved by technology

[0003] The purpose of the present invention is to overcome the problems existing in the prior art, and provide a facility based on the anti-backflow inspection well, which can fundamentally solve the problem of residential, commercial, office, commercial complexes, factory buildings and other industries in the process of urban construction. And civil construction park due to the municipal rainwater and sewage backflow into the park due to the shallow burial of the municipal rainwater and sewage pipe network or the excessive amount of municipal rainwater and sewage, resulting in serious water accumulation or waterlogging in the park
