摘要:

在深基坑开挖中,如地下承压水埋藏较浅，采用管井降水降低地下水位后，对管井采取不同的措施进行封井，确保地下水位控制在施工要求的范围之内。重点介绍了山东潍坊万达广场深基坑降水施工方法及具有承压水头的减压井封井方案和封井施工方法。

Abstract:

For deep foundation pit construction, if in the condition of shallow buried underwater confined water, the tube well is applied to lower underground water level and different measures are taken for well sealing to ensure the underground water level to be controlled within the scope of the construction requirements. The paper introduces the dewatering construction for deep foundation pit in a project of Shandong and the relative well sealing plan as well as the construction process for the relief well with confined water head.
