Complicated water area inclined rock face large-diameter cast-in-place pile and construction method
The invention relates to a complicated water area inclined rock face large-diameter cast-in-place pile. The complicated water area inclined rock face large-diameter cast-in-place pile comprises a drilling platform, a steel pipe pile, a steel pile casing and a cast-in-place pile body, the steel pipe pile is arranged on an inclined rock face, the top of the steel pipe pile is connected with the drilling platform, and the bottom of the steel pipe pile is provided with an inner pocket, an outer pocket and a separate type heavy steel plate; the drilling platform is provided with a spacing steel plate and a circular groove which has the same external diameter of the steel pile casing, and the steel pile casing penetrates through the circular groove and extends into the inclined rock face; the drilling platform is connected with the steel pipe pile which is arranged below the drilling platform through an I-shaped steel beam; the steel pile casing comprises an original pipe and a secondary following pile casing, the original tube and the secondary following pile casing are welded and fixed through a stiffened steel panel, and the inner wall of the secondary following pile casing is provided with a limiting block; the steel pile casing is internally provided with a reinforcement cage, and the cast-in-place pile is formed by pouring of concrete. The problem of deepwater shallow cover layer inclined rock face cast-in-place pile construction is effectively solved, compared with steel cover box cofferdam construction, the steel using amount is greatly reduced, the construction cost and time are saved, and the safety factor is high.
