Construction method of sewage pipeline

Abstract

The invention discloses a construction method of a sewage pipeline. The construction method comprises the following processes of GPS positioning and lofting, pavement cutting and breaking, pipeline groove supporting and excavation, pipeline foundation construction, inspection well mounting, pipeline mounting, pipeline groove backfilling, and pavement recovery. The pavement cutting and breaking process comprises the following steps of pipeline axis measuring and lofting, pavement cutting edge line marking, pavement cutting, and pavement breaking. When the pipeline groove supporting and excavation process is carried out, steel plate pile supporting is adopted when the depth is larger than 3.5 m. The pipeline foundation construction process comprises the following steps of foundation levelingand compacting, cushion layer paving, manual primary leveling, cushion layer compacting, and compactness detecting. The inspection well mounting process comprises the following steps of well bottom elevation rechecking, well bottom foundation checking, well chamber hoisting and splicing, and inspection well and pipeline connecting. The pipeline mounting process comprises the following steps of pipeline hoisting and manual mounting, pipeline axis positioning, pipeline joint cleaning, cutting, elevation and positioning retesting, and pipeline hot-melt welding or socket welding. According to theconstruction method, the construction period is greatly shortened, and the engineering efficiency is improved.

Description

technical field [0001] The invention relates to a construction method of a sewage pipeline. Background technique [0002] In order to make the rural living environment more and more beautiful, our country is comprehensively promoting the pace of rural domestic sewage treatment projects.
