工程深基坑施工降水技术应用分析

Analysis of Application of Precipitation Technology in Deep Foundation Pit Construction

深基坑降水与土方开挖、桩基工程的施工顺序,将直接影响工程的进度及质量;降水管井的材质选择,降水系统的封闭性等将对降水效果产生关键性影响。通过工程实践经验,对西北地区深基坑施工降水技术应用进行简要的概述、分析,为类似工程提供借鉴。

The sequence of the deep foundation pit precipitation and earth excavation,and the pile foundation project construction process will directly affect the progress and quality of the project;the choice of the material of the precipitation pipe well and the closedness of the precipitation system will have a key impact on the precipitation effect.Based on practical engineering experience,this paper briefly summarizes and analyzes the application of precipitation technology in deep foundation pit construction in the northwest region,and provides reference for similar projects.
