哈尔滨松花江边超深基坑降水实践

Practice of Ultra-deep Foundation Pit Dewatering by Songhuajiang River

在临江建筑施工中,基坑降水是关系整个基坑开挖的关键环节之一,也是影响工期和整个工程施工质量的重要因素。对哈尔滨市一临松花江超高层建筑超深基坑地下水处理的设计及实施过程进行了介绍,对施工过程的设计参数选取、施工经验及不足进行了探讨和总结。

Foundation pit dewatering is one of the key links in the excavation for building construction by the riverside and is an important factor affecting the construction period and the construction quality of the whole project. The paper introduces the design and implementation process of groundwater treatment for the ultra-deep foundation pit of a high-rise building by Songhuajiang. The selection of the design parameters in the construction process,the construction experience and deficiency are discussed and summarized,which can be reference to the subsequent construction.
