| 摘 要： | 地下构筑物的发展使深基坑作业也随之俱增。在内蒙庆华青海煤化工业园火车卸车槽基坑降水中,采用环状管井降水技术对该基坑进行地下降水,工程实施后降水效果明显,基坑开挖后土体固结良好,达到设计要求。该项技术的实施,为在高海拔地区地下水埋藏浅、基坑相对较深且水量相对丰富的软土地区的构筑物基坑降水积累了一定的经验。

| Abstract: | The development of underground structures makes the deep-pit operations increasing.In train unloading chutes foundation pit of Mongolia Huaqing Qinghai Coal Chemical Industry Park,we adopt precipitation technologies of the annular tube wells for the precipitation in the underground pit.It meet the design requirements that the effect of precipitation is obvious after the implementation of the project.The soil is well consolidated after excavation.According to the implementation of this technical,we can accumulate some experience of designing the precipitation in the high elevational pit which is buried in shallow groundwater and relatively deep in the soft soil in which water is relatively abundance. |

| Keywords: | soft soil structure pit tube well precipitation |
