Sewage inspection well structure performing desilting without stopping water and construction method of sewage inspection well structure

Abstract

The invention relates to a sewage inspection well structure performing desilting without stopping water and a construction method of the sewage inspection well structure. An inspection well composed of a concrete bottom plate and a well body is included; the portion, at the water inflow end of the inspection well, of the well body is provided with a water inflow sewage pipeline, and the portion, at the water outflow end of the inspection well, of the well body is provided with a water outflow sewage pipeline; flow guiding walls which are vertical in the longitudinal direction are symmetricallyarranged on the two sides of the water outflow end in the inspection well, and partitioned areas are formed on the two sides; each partitioned area is divided into a U-shaped residue sediment area and a buffering storage area by a dirt intercepting flashboard in the transverse direction, and each U-shaped residue sediment area and the corresponding buffering storage area are arranged front and back; and the bottom face of each U-shaped residue sediment area sinks and is lower than other areas. According to the sewage inspection well structure performing desilting without stopping water, the function partitioning concept of the sewage inspection well is put forwards for the first time, and the structural type that the symmetrical U-shaped residue sediment areas and U-shaped residue sediment barrels are combined in a separated manner is adopted on the two sides in the sewage inspection well by means of the flow guiding thought; and synchronous design is adopted, but the corresponding portions independently play roles, the sewage inspection well desilting work in the state without stopping water is successfully achieved, the structural system is reasonable in stress and the operationand maintenance cost can be remarkably lowered.

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...
