摘要
给排水工程中,对埋深较大而横截面尺寸相对不大的构筑物,采用大开槽施工将会造成占地面积大、土方量多等弊病,有时还受到施工场地限制。为此,常采用沉井法施工。沉井法适用于高地下水位、土质松软、流砂地段以及现场狭窄地段修建深埋构筑物。本文中沉井体积大,故采取先开挖再采用砂垫层很上铺承垫木扩大刃脚的施工技术。
Abstract
In the water supply and drainage engineering project, for the large of buried depth cross-sectional size relatively modest structures, if we adopt large notching construction it will cause a lot of disadvantage, such as cover more area, make laege earth v
