北京新机场深基坑井点降水施工技术

Well-Point Dewatering and Construction Technology for Deep Foundation Pit of Beijing New Airport

井点降水是一种人工降低地下水位的方法,用于地下水位较高的施工环境。结合北京新机场深基坑井点降水施工实例,介绍深基坑井点降水方案,详细阐述井点降水施工方法,总结形成了深基坑井点降水施工技术,可为类似工程施工积累经验。

Well point precipitation is a method of artificially reducing the groundwater level,which is used in the construction environment with high groundwater level.Combined with the construction example of well point dewater⁃ing of deep foundation pit in Beijing new airport,this paper introduces the well point dewatering scheme of deep foun⁃dation pit,expounds the well point dewatering construction method in detail,summarizes and forms the well point de⁃watering construction technology of deep foundation pit,and accumulates experience for the construction of similar projects.
