The surrounding environment of Jinyang Street station of the first phase of Taiyuan City Metro Line 2 is complex. It is located in the city roads, traffic is large and the geological environment is complex. How to reduce the groundwater level in the construction process is a complex technical problem. In this paper, dewatering dewatering deep wells, vacuum dewatering deep wells, water level observation wells are used to carry out the construction of underground water level. In this paper, the construction technology of dewatering in foundation pit is introduced in detail, which can provide technical reference for similar foundation pit dewatering in the future.%太原市轨道交通2号线一期工程晋阳街站,周边环境复杂,位于城市主干道,车流量较大,地质环境复杂,如何在施工过程中降低建筑范围内地下水位是一项比较复杂的技术难题,本文采用疏干降水深井、减压降水深井、水位观测井对地下水位进行降水施工.针对降水工艺及运行详细介绍了基坑内降水施工技术,为今后类似基坑内降水提供技术参考.
