Practice of Dewatering for a Riverside Cofferdam with High Permeability and Strong Recharge in Overseas
With the extensive increasing involvement of domestic enterprises in the construction of"the Belt and Road Initia-tive"projects,domestic enterprises need to face new standards and new environments overseas.Consequently,they need to se-lect appropriate engineering design,construction and management methods that are tailored to local conditions.Due to the high permeability of soil strata,abundant groundwater recharge,and difficulties in local groundwater slurry wall construction,an o-verseas riverside and seaside pit project encounters an extremely large challenge in dewatering inside the foundation pit.The success or failure of dewatering the excavated area affects the project schedule and cost.This article discusses a deep excavation dewatering project to introduce the problems encountered in the hydrogeological investigation,design,and construction process of the deep excavation dewatering engineering.The experiences gained from projects involving large groundwater volume,strong recharge,and intense corrosion groundwater challenges,and puts forth specific solutions.The objective is to serve as a reference for the construction of similar projects.
