Construction method of a sewage pipeline

Abstract

The invention discloses a sewage pipeline construction method, comprising the following processes: GPS positioning and setting out, road surface cutting and breaking, pipeline trench support and excavation, pipeline foundation construction, inspection well installation, pipeline installation, pipeline trench backfilling and Pavement restored. Road surface cutting and demolition process: pipeline axis measurement and setting out, marking the road surface cutting edge, road surface cutting, road surface demolition. When carrying out pipeline trench support and excavation process, steel sheet pile support is used when the excavation depth is greater than 3.5m. Pipeline foundation construction process: foundation leveling and compaction, cushion laying, artificial initial leveling, compaction of the cushion and detection of compactness. Inspection well installation process: check the bottom elevation → check the bottom foundation → hoisting and splicing of the well chamber → connection between the inspection well and the pipeline. Pipeline installation process: Pipeline hoisting, manual installation→pipeline axis positioning→pipeline interface cleaning→cutting→elevation and positioning re-measurement→pipeline hot-melt welding or socketing. The invention greatly shortens the construction period and improves the engineering efficiency.

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. At present, most rural villages and towns do not have sewage pipes, and the drainage facilities are seriously lagging behind. Most of the sewage is discharged into farmland and streams nearby through ditches, causing certain pollution to the water bodies in the urban area, seriously affecting the quality of life of residents and the ecological appearance of the city, and restricting rural areas. develop. [0003] Rural domestic sewage treatment mainly includes sewage collection projects, sewage treatment projects, and sewage upgrading projects. The sewage collection project mainly includes the laying of main and branch pipelines, inspection wells, and household pipes in each administrative ...
