Sewage inspection well structure and construction method for non-stop desilting

Abstract

The invention relates to a sewage inspection well structure and a construction method for non-stop dredging and silting, comprising an inspection well composed of a concrete bottom plate and a well body. Sewage pipes for water outlet are provided; longitudinal and vertical diversion walls are symmetrically arranged on both sides of the water outlet end in the inspection well, forming a separation area on both sides, and the separation area is again divided into U-shaped slag areas arranged in front and rear by the horizontal sewage intercepting gates And the buffer area, the bottom surface of the U-shaped sediment area sinks and is lower than the other areas. The invention proposes the concept of functional zoning of sewage inspection wells for the first time, and with the help of the diversion concept, the symmetrical U-shaped sediment area and the U-shaped sediment barrel are separated and combined on both sides of the sewage inspection well. The dredging work of sewage inspection wells in the state of non-stop water is completed, the structural system is reasonably stressed and the operation and maintenance costs can be significantly reduced.

Description

technical field [0001] The invention belongs to the field of municipal engineering, and in particular relates to a structure of a sewage inspection well for desilting without stopping water and a construction method thereof. Background technique [0002] Rain and sewage diversion can effectively protect the urban ecological environment. As an important part of the urban drainage system, the sewage pipeline system is one of the foundations of urban safety. With the expansion of city scale, the mileage of municipal sewage pipes is increasing rapidly year by year, and the detection and repair of old pipe networks, as well as the daily operation and maintenance costs are increasing, because urban road collapse disasters frequently occur due to leakage of old pipe networks. Although various detection technologies and non-excavation repair technologies have been developed rapidly, which has beneficially ensured the safety of the urban drainage pipeline system, it is an indisputabl...
