Technology of Support and Water-Seal Design of Deep Foundation Pit in Deep Silty Fine Sand Layer

Based on the engineering,the support selection,water-seal design of deep foundation pit in deep silty fine sand layer was introduced,in which the curtain for cutting off water was improved and the isolation pile was set to make sure the support success in island of river center by pile-anchor system.It showed the engineering was secure,the construction period was shortened and the cost was lowered.
