Abstract

Specific retaining structures and water intercepting assistant technologies are adopted on basis of the different environment conditions, so as to achieve rapid, safe and successful construction of the deep foundation pit. In the end, the rigidity of the retaining structure is improved, the water leakage of the foundation pit is brought into control, the safety of the surrounding environment and the foundation pit is guaranteed and rapid and safe construction of the foundation pit is achieved.
