深基坑工程坑内地下水位平衡控制施工要点分析

ANALYSIS ON KEY POINTS IN CONSTRUCTION OF BALANCE CONTROL OF GROUNDWATER LEVEL IN DEEP FOUNDATION PIT ENGINEERING

针对在深基坑工程的建设过程中,时常遇到富含地下水的施工地点,南通建工集团股份有限公司发明的基坑内基础底板下降水井的施工方法,有效克服常规基坑降水井施工方法的不足之处,避免降水管井穿越基础底板结构,实现坑内降水井水位的协调平衡与坑内水位可视化动态平衡控制,使坑内降水量得到有效控制,缓解坑外环境设施地下水位控制难度。

Aiming at the construction process of deep foundation pit projects that often encounter construction sites that are rich in groundwater, Nantong Construction Engineering Group Co., Ltd. invented the construction method of the foundation floor dewatering well in the foundation pit, which effectively overcomes the conventional foundation pit dewatering well construction method, avoids the dewatering pipe crossing the foundation floor structure, and the coordinated balance of the water level of the dewatering well in the pit and the visual dynamic balance control of the water level in the pit are realized, so that the precipitation in the pit can be effectively controlled, and the difficulty of controlling the groundwater level of environmental facilities outside the pit is alleviated.
