摘要
苏州市区东部地质多属于以陆相为主的海陆交互相沉积物,轨道交通1号线车站基坑大多处在粉土粉砂中,如何在这种地质情况下处理钻孔灌注桩桩间涌水涌砂,就成了施工中的重要技术环节。以苏州地铁1号线西环路站为例,介绍在特殊地层分布情况下,如何运用水平向井点降水技术解决上述问题。
The eastern part of Suzhou is mostly located in the geology of continental paralic sediments, the pits of rail transit Line 1 are mostly in the silt. How to deal with the geological conditions by boring and grouting to stop the water and sand gushing become the important technical issues in the construction. Taking Xihuan station Suzhou rail transit as an example, how to use the horizontal well concerning the watering level control technology to solve the above-mentioned problems in such a special stratigraphic distribution is discussed.
