傍河深基坑降水技术研究

Study on Dewatering Technology for Deep Foundation Pit Along River

摘要:

以首钢迁钢生活小区2、4号基坑降水工程为例，针对傍河深基坑具有靠近补给源及含水层厚度大且渗透性强等特点，从降水方案选取、降水设计、降水井施工、对周边的建筑和地下水影响及采取的措施等几个方面，对傍水深基坑降水技术进行了研究，以期为该区域及类似工程提供借鉴和参考。

Abstract:

Taking 2 cases as the examples and based on the characteristics of being near to the recharging source, thick aquifer and strong permeability, the study was made on dewatering technology for deep foundation pit along river in the dewatering scheme selection, dewatering design, dewatering well construction and the effects on the surrounding buildings and underground water, in order to provide the reference to the similar projects in the area of Qiangang of Capital Steel Company.
