Self-drilling steel pipe pile continuous wall construction method and steel pipe pile continuous wall used in self-drilling steel pipe pile continuous wall construction method
The invention relates to a self-drilling steel pipe pile continuous wall construction method and a steel pipe pile continuous wall used in the self-drilling steel pipe pile continuous wall construction method in the field of foundation pit support projects. According to the steel pipe pile continuous wall, a power device (5), a self-drilling drill bit (6) and a self-drilling drill pipe (7) are arranged in a steel pipe pile (1), during inserting construction, the self-drilling drill pipe (7) and the self-drilling drill bit (6) are driven through the power device (5), the drilling disturbing construction is carried out on the soil body at the bottom of the steel pipe pile (1), the inserting construction difficulty and the effect of inserting construction on the surrounding environment are greatly reduced, and the effect of pile pulling construction on the surrounding environment can be reduced. Construction equipment is simple, efficiency is high, cost is low, and the effect on the surrounding environment is low.
