高聚物注浆及离心浇筑法在检查井修复中的应用
Application of Polyurethane Injecting Method and Sprayed Cementitious Material Method in Manhole Rehabilitation
摘要
Abstract
In view of the damage and leakage of municipal pipe manhole caused by aging and other factors,which can easily cause water environment pollution,soil erosion,ground collapse,and other problems,base on a cer-tain inspection well in a high water level area of Tianjin,this paper elaborate on the principles,design ideas,and construction processes of high polymer grouting and centrifugal pouring methods for non excavation repair inspection wells.Engineering practice has shown that this method can effectively and efficiently repair struc-tural defects in old inspection wells in high groundwater level areas without excavation.关键词
