Construction process for communicating pipeline with pool body

Abstract

The invention relates to a construction process for communicating a pipeline with a pool body, and belongs to the field of sewage pool body transformation. The construction process comprises the following steps of (S1) selecting a proper position around the pool body, and determining a construction position of a drainage well; (S2) performing earth excavation, and pouring a concrete cushion layer;(S3) binding bottom plate steel bars, erecting a formwork, and pouring bottom plate concrete; (S4) binding wall steel bars, installing a drainage pipe, erecting a formwork, and pouring wall concrete;(S5) selecting a punching-through area on the side wall of the original pool body, and drilling the edge of the punching-through area, wherein the original pool body is not drilled through, the number of drilled holes is large, and the drilled holes are densely arranged along the edge of the punching-through area; (S6) prying concrete blocks in the punching-through area by using a crowbar; (S7) manufacturing a movable steel cover plate so as to seal the drainage well; and (S8) performing earthwork backfilling. The construction process has the effects that underwater construction is not needed, and the construction difficulty and cost are reduced.

Description

technical field [0001] The application relates to the field of renovation of sewage pool bodies, in particular to a construction process for connecting pipelines with pool bodies. Background technique [0002] During the construction process of the sewage treatment plant upgrade and renovation project, it is often encountered the problem of difficulty in connecting the water inlet or drainage pipe with the pool body. The traditional construction process uses underwater operations or intermittent water cut-off construction, which not only requires high construction costs and low operating costs. Difficult, more dangerous, many potential safety hazards, longer construction period, difficult to maintain and overhaul later. Contents of the invention [0003] In order to reduce the problems of construction difficulty, high cost, difficult operation and high risk of installing drainage pipes on the pool, the application provides a construction process for connecting pipes with a...
