Overall hoisted prefabricated underground continuous wall structure and prefabricating and construction method thereof

The invention discloses an overall hoisted prefabricated underground continuous wall structure and a prefabricating and construction method thereof. The overall hoisted prefabricated underground continuous wall structure comprises a prefabricated underground continuous wall body, joggling joints are correspondingly arranged at both ends of the prefabricated underground continuous wall body, and sealing grooves are formed respectively in the two sides of the wall body at the butt joint portion of a prefabricated underground continuous wall and are internally provided with water-swelling rubbersealing strips. The butt joint portion of the prefabricated underground continuous wall body is provided with a waterproof joggling structure, the strength is high, slide and dislocation occurring between the wall bodies can be effectively prevented, the waterproof function is achieved, and concrete cracking can be prevented; prestress steel bars are arranged at the two sides of the wall body, thestrength of the wall body can be improved, and the wall body is prevented from being damaged in the transportation process; the steel bars are reserved at the top of the wall body and facilitate subsequent machining; besides, the prefabricated underground continuous wall is prefabricated integrally, concrete pouring is not required later, and a crane is adopted for hoisting and assembly in the construction process, which helps to shorten the construction period.
