Description

Prefabricated assembled rain sewage inspection shaft

Technical Field

The utility model relates to the technical field of urban drainage, in particular to a prefabricated assembly type rain sewage inspection well.

Background

The urban drainage system is divided into two systems, namely a diversion system and a confluence system, and most cities adopt the diversion system, namely the rainwater and the sewage are respectively discharged. Units or living areas along the urban road are generally organized drainage pipes for collecting and draining rainwater and sewage to the lower part of the urban road, commonly called municipal drainage pipes. Rainwater and sewage are discharged to a water body or a sewage treatment plant through a municipal drainage pipeline. Inspection wells are required to be arranged at the joint of the municipal drainage pipeline at intervals, at the pipeline turning and branch pipes. The municipal drainage pipe has the characteristics of larger pipe diameter and larger inspection well. Meanwhile, in order to facilitate the regular operation of checking, cleaning, dredging and the like of the underground drainage pipeline buried in the ground, an inspection well is arranged in the underground drainage pipeline network. But among the prior art, because the inlet channel flows into the rainwater and sewage of inspection shaft and generally can carry silt, and the pipe diameter size of inlet tube is unchangeable, and rivers flow change is indefinite in the inlet tube, when rivers flow in the inlet tube is little, the rainwater and sewage velocity of flow in the inlet tube can slow down, and then make silt deposit in the inspection shaft easily, influence the circulation of later stage rainwater and sewage, in addition inconvenient maintainer clear up silt when depositing in the inspection shaft and piling up too much silt, need improve this, and current inspection shaft is mostly cement and concrete casting, construction cycle is longer, can influence normal traffic.

Although the rainwater and sewage backflow prevention inspection well disclosed in the Chinese patent application publication No. CN 113565188A solves the backflow problem to a certain extent, impurities in rainwater and sewage still enter the inspection well, if accumulation phenomenon occurs, the cleaning is inconvenient, and in addition, the whole inspection well is still formed by pouring reinforced concrete at a construction site, the construction period is long, and traffic is influenced.
