Application of Point in-situ Solidification Repair Technology in Municipal Engineering
The underground drainage network in the urban area of Huizhou City has been in operation for a long time,resulting in local defects such as disconnection,rupture,and leakage inside the pipeline,which affects the normal operation of the pipeline.Huizhou Water Environment Project Department adopted a point like in-situ solidification repair construction technology to carry out targeted non excavation repair treatment for the defects generated inside the pipeline.This construction requires the repair of 28 km of underground drainage pipelines within the urban area of Huizhou.After screening,the number of defects was 934,and a total of 29 defects were repaired using spot in-situ solidification repair technology.Based on the comprehensive improvement project of water environment in Jinshan New City,Huizhou,this paper summarizes a set of local repair construction techniques for drainage pipelines.It effectively treats local defects in drainage pipelines,greatly reducing pipeline operation and maintenance costs,improving project management efficiency,and has broad application prospects.
