Experimental Study on Intelligent Dewatering of Deep Foundation Pit with Suspended Impervious Curtain
The traditional foundation pit dewatering method has limited real-time monitoring and control capabilities for groundwater level.This paper studies an intelligent dewatering system for deep foundation pits with suspended impervious curtain.The system can monitor the changes in water levels inside and outside the foundation pit in real time and effectively control the depth of foundation pit dewatering.An indoor experimental study on intelligent dewatering of foundation pits was conducted by changing the insertion depth and dewatering depth of the suspended impervious curtain.Firstly,the influence of dewatering depth on the pumping interval inside the pit was analyzed,and further research was conducted on the variation law of the water level outside the pit under different dewatering depths and the insertion depth of the impervious curtain.The results show that during the intelligent dewatering process,the water level height in the foundation pit changes in a wave shape;as the depth of foundation pit dewatering increases,the pumping frequency of the dewatering system accelerates,and the fluctuation amplitude of the water level outside the pit decreases;the depth of the impervious curtain has a relatively small impact on the fluctuation of the water level outside the pit,but as the depth of the impervious curtain increases,the water level outside the pit significantly decreases.
