在当今城市的地铁建设当中,地铁施工是地铁建设当中的重要建设内容。明挖施工法在地铁的降水工艺当中是一种被普遍使用的手段,它是利用挖开地面来完成车站主体结构之后,填充基坑来恢复地面。针对地铁明挖施工的技术特点,在地铁明挖车站的施工当中需要重视防降水工作的进行。 In the metro construction in today’s city, subway construction is an important part of the subway construction. The digging construction method is a commonly used method in the subway precipitation process, which is to fill the foundation pit to recover the ground after digging the ground to complete the main structure of the station. In view of the technical characteristics of MTR excavation, it is necessary to pay attention to the work of precipitation prevention in the construction of subway digging stations.
