地下连续墙在南水北调泗阳泵站基坑防渗工程中的应用

摘要

在基坑周边实施多头小直径水泥搅拌桩围封降水的基础上，依据工程周围工作环境和地质条件，根据射水法造墙原理，阐述地下连续墙（以下简称地连墙）施工流程、技术要点以及应用中发生串浆问题的解决办法，为今后类似大型泵站基坑防渗处理提供借鉴经验。%under the condition of implementing multi-head small diameter cement mixing pile in foundation pit enclosure precipitation,according to the working environment and geological condition of the project,based on water jetting principle,this paper explains the construction process,technique points and solutions for grout leaking problems of underground diaphragm wall,which can provide a reference for future pile seepage control treating of similar large pumping station foundation.
