Steel structure of pre-stress high-strength concrete pipe pile body

The invention relates to a steel structure of a pile used for construction, in particular to a steel structure of a pre-stress high-strength concrete pipe pile body. The steel structure comprises a plurality of pre-stress longitudinal ribs, a spiral net barrel and a plurality of annular hooping ribs, a plurality of steel wires intersect and bound together in the direction opposite to the spiral direction of a spiral angle at certain screw pitch to form the spiral net barrel, the pre-stress longitudinal ribs are evenly distributed in a circle formed by the spiral net sleeve in the circumferential direction, a circle formed by the pre-stress longitudinal ribs and the circle formed by the spiral net barrel are concentric, and the annular hooping ribs are evenly bound to the outer side of the spiral net barrel from top to bottom. Compared with the prior art, the spiral net barrel of the steel structure of the pre-stress high-strength concrete pipe pile body can greatly increase the anti-shearing bearing capacity of the pre-stress pipe pile, the anti-bending performance is enhanced by the pre-stress longitudinal ribs, meanwhile, the integrality between the pre-stress longitudinal ribs in the pipe pile body can be improved due to match between the spiral net barrel and the annular hooping ribs, and the anti-seismic energy consumption performance is enhanced.
