管井降水在深基坑开挖中的设计与施工

Design and Construction of Tube Well Precipitation in Deep Foundation Pit Excavation

管井降水是人工降低地下水位的常用方法,具有工程费用低、易于施工和抽水效果好的特点。在繁昌县城南污水处理工程建设中,粗格栅及进水泵房是整个工程污水汇集和提升集中点,埋置深度10.2m。在粗格栅及进水泵房的深基坑开挖过程中,采用管井降水,取得了良好的效果。

Tube well precipitation is commonly used in the artificially reducing the ground water table, which has the characteristics of low cost, easy construction and good pumping effect. In the construction of sewage treatment project in Fanchang, coarse grating and pump room are the sewage collection and ascension place, and the buried depth of them is l O .2m. In the excavation process of deep foundation pit of coarse grating and pump room, tube well precipitation was used, and the effect is good.
