The LNG Receiving Station project in Shenzhen is located in a land reclamation area with complicated geological conditions.The thickness of diaphragm wall is 1.5 m,the depth is up to 62 m,and is extremely difficult to construct.During the construction process,slot wall reinforcement technology is used to ensure the stability of slot formation,and milling-drilling-milling technology is used to address the problem of ultra-deep rock of diaphragm wall.The super-large reinforcement cage of underground continuous wall is built and lifted in one time to ensure the construction quality and safety,and the green construction is achieved by adopting the green and environment-friendly mud circulation treatment technology.The construction technology of ultra-deep diaphragm wall applied in the project yielded positive results and has the potential be become more widely used.
