Case Analysis of Tube Well Dewatering of the Foundation Pit Neighboring River in Lhasa Region

摘要:

管井降水是一种设备简单、排水效率高的降水方法，在地下工程的施工中有广泛的应用。本文结合拉萨京藏交流中心邻河基坑降水项目的施工实践，参考实际施工效果和实际施工条件，研究邻河基坑管井降水的方案优化，分析降水过程中的重点和难点，增强降水方案的科学性，提高降水效率。

Abstract:

Tube well dewatering is widely used in the construction of underground works for its high drainage efficiency with simple equipment. This paper studied the scheme optimization of the tube well dewatering of a foundation pit by river and analyzed the key and difficult points in the dewatering process in high altitude area based on the constructin practice of dewatering project by river in Lhasa and with the reference of the actual construction effects and the actual construction conditions. As the dewatering scheme is more scientific, the dewatering efficiency is also improved.
