Steel pipe screw anchor pile group foundation
The invention provides a steel pipe screw anchor pile group foundation. The steel pipe screw anchor pile group foundation comprises a base, a plurality of steel pipe screw anchors perpendicular to thebase are fixed to the middle of the bottom of the base, and steel pipe screw anchors forming a certain angle from 2 degrees to 15 degrees with the steel pipe screw anchors perpendicular to the base are fixed to the periphery of the bottom of the base. Pile bodies of the steel pipe screw anchor pile group foundation are arranged in a slightly inclined manner and can bear relatively large longitudinal force and horizontal force; the steel pipe screw anchors greatly improve the bearing capacity and reduce the length of the pile bodies by 30% or above; and the manufacturing cost is reduced by about 19%-24% compared with that of steel pipe piles. The steel pipe screw anchors have a small diameter and a low piece weight, so that transportation in river network areas is facilitated.
本发明提出一种钢管螺旋锚群桩基础，包括底座，所述底座底部中间固定有若干垂直底座的钢管螺旋锚，所述底座底部四周固定有与垂直底座的钢管螺旋锚成一定角度的钢管螺旋锚，所述角度范围为2°至15°。本发明的桩体使用微倾斜布置，可承受较大的纵向力和水平力；钢管螺旋锚大幅提升承载力，降低桩体长度30%以上；造价较钢管桩降低约19%‑24%。钢管螺旋锚直径小单重轻，便于河网地带运输。
