摘要
基坑工程中,对地下水处理的方法应用比较广泛的有许多种,止水帷幕就是其中之一。本文介绍了止水帷幕常用的施工方法及其优缺点,重点介绍了长螺旋旋喷搅拌水泥土帷幕技术在基坑工程中的应用情况,该技术很好地解决了目前在类似北京地区较硬土层中施工帷幕造价高、施工质量可控性差、止水效果不理想等问题,为类似需要做止水帷幕的基坑工程提供了借鉴。
In excavation engineering,groundwater treatment methods are widely used in many kinds,and waterproof curtain is one of them.The paper introduces the general method of water curtain and their advantages and disadvantages,and emphatically introduces the application of long auger rotary-jet mixing soil-cement curtain pile technology in engineering.This technology has greatly solved the current problems in relatively hard soil in Beijing like high cost in building curtain,low controllability in construction quality,and unreasonable water seal effect,etc.for similar waterproof curtain of foundation pit engineering examples provided.
