Research on Efficient Construction Technology of Water-facing Steel Cofferdam for Urban River-crossing Cable-stayed Bridge
Based on the actual situation and construction characteristics of the rapid construction of the 2#main tower lock buckle steel pipe pile cofferdam of the EPC project of Qingjiang Municipal Bridge,this paper introduces the efficient construction technology of the water-facing steel cofferdam for urban river-crossing cable-stayed bridge.In order to ensure the quality of steel cofferdam,ensure the construction safety,shorten the construction period and reduce the construction cost,the guide hole construction technology of impact drill combined with rotary drill is finally determined,which can be used for reference in similar engineering.
