Research on Emergency Treatment Technology for Water Inrush in Deep and Large Foundation Pit
With the continuous acceleration of urbanization construction in China,the number of subway deep and large foundation pit excavation projects is increasing,and the water inrush accident in deep and large foundation pit has brought great obstacles to foundation pit excavation and subway construction.Taking a deep and large foundation pit project in a limestone area of Guangzhou as an example,this paper discusses to mainly adopt the method of"emergency water inrush rescue+drilling construction+modified mortar and cement clay paste construction"to realize the blocking of water inrush around the basement,aiming to provide practical experience for the blocking of water inrush in the excavation construction of subway foundation pits in China.
