Variable cross-section spiral pipe pile with torsion-resistant part
The invention provides a variable cross-section spiral pipe pile with a torsion-resistant part, and belongs to the field of concrete prestressed piles. According to the spiral pipe pile, through the design of the protruding table, the center through hole and the anti-torsion piece, the problem that mold drawing is inconvenient when the spiral pipe pile is produced and the problem that the pile body is fractured due to the fact that torsion at a certain position on the pile body is too large are solved. The variable-cross-section spiral pipe pile with the anti-torsion piece comprises a columnar part, a spiral part and the anti-torsion piece. The spiral part is spirally distributed in the circumferential direction of the outer wall of the columnar part; a central through hole is formed in the columnar part, the at least one anti-torque part is fixedly installed on the inner wall of the central through hole and penetrates through the two ends of the central through hole, and the central through hole and the anti-torque part form a rotation stopping structure; protruding tables are arranged on the spiral part, and every two adjacent protruding tables in the length direction of the spiral pipe pile are spaced by 180 degrees in the circumferential direction.
本发明提供一种具有抗扭力件的变截面螺旋管桩，属于混凝土预应力桩领域。本发明通过所述凸起台、所述中心通孔和所述抗扭力件的设计，解决了在生产螺旋管桩时拔模不便的问题和桩体上某一处扭力过大造成桩体断裂的问题。所述具有抗扭力件的变截面螺旋管桩包括：柱状部、螺旋部和抗扭力件；所述螺旋部沿所述柱状部的外壁的周向螺旋分布；所述柱状部内设有中心通孔，至少一件所述抗扭力件固定安装在所述中心通孔的内壁上且贯穿所述中心通孔的两端，所述中心通孔和所述抗扭力件形成一个止转结构；所述螺旋部上设置有凸起台，沿所述螺旋管桩长度方向相邻的两个所述凸起台在周向上间隔180°。
