摘　　要：为保证地下工程基坑的稳定性,先进的降水施工技术十分关键。该文提出了富水地质条件下地铁车站深基坑轻型井点降水施工技术。首先进行基坑轻型降水井点的平面布置,并计算相关参数;接着进行轻型井点的降水管布置和降水点的安插;最后启动轻型井点降水点。实例测试结果显示,施工后基坑内的渗水量明显减少,深基坑的渗水量接近于0,从而增强了基坑的稳定性,为后续施工提供了可靠的保障。To ensure the stability of underground engineering foundation pits,dewatering construction is a crucial step.Therefore,this article proposes a lightweight well point dewatering construction technology for deep foundation pits of subway stations under rich water geological conditions.Firstly,carry out the plan layout of the lightweight dewatering well points in the foundation pit and calculate the relevant parameters.Next,arrange the precipitation pipes and install the precipitation points for the light well points,and finally activate the light well point precipitation points.The test results of the example show that the seepage volume in the foundation pit is significantly reduced after construction,and the seepage volume in the deep foundation pit is close to 0,thereby enhancing the stability of the foundation pit and providing reliable guarantee for subsequent construction.
