Integral Lifting Option for Reinforcing Cage of Ultra-large Concrete Diaphragm Wall

In the coastal soft soil area,when the foundation pit is excavated up to a certain depth,the conventional design and construction method of concrete diaphragm wall can’t satisfy the project requirement,and it is more difficult to construct the ultra-deep concrete diaphragm wall.Based on the construction of concrete diaphragm wall of Yujiabao Traffic Hub Project in Tianjin Binhai New area,the lifting options for the reinforcing cage of ultra-large concrete diaphragm wall are compared and researched.In addition,the effective construction plan are summarized and applied well in some projects.
