摘要
土方开挖过程中,当基坑、基槽的底面标高低于地下水位时,由于土的含水层被切断,地下水会不断渗入基坑,给施工带来不便甚至影响工程质量,本文以一大型地下停车场为例,介绍了深井井点降水的设计、施工和运行的效果。
During excavation process of earthwork, when bottom elevation of foundation pit, foundation trench is below the underground.water level, because of the earth was cut off, groundwater will continue to infiltrate into the pit, which bring inconvenience for construction influencing construction engineering quality. With a large underground parking as an example, this paper introduces the design, construction and operation effect of water wells.
