PHC pipe pile and spiral steel pile combined pile foundation for photovoltaic support
The invention belongs to the technical field of civil engineering, and particularly relates to a PHC pipe pile and spiral steel pile combined pile foundation for a photovoltaic support, the combined pile foundation is composed of a bottom plate, stiffening ribs, a PHC pipe pile, a PHC pipe pile end plate, a steel pipe pile, spiral blades and a pile tip; the spiral blade is welded to the outer surface of the steel pipe pile, the PHC pipe pile end plate is welded to the top end of the steel pipe pile, the PHC pipe pile is welded to the PHC pipe pile end plate, the bottom plate is welded to the top end of the PHC pipe pile, the pile tip is welded to the bottom end of the steel pipe pile, and the stiffening ribs are welded to the bottom face of the bottom plate and the outer surface of the steel pipe pile. The PHC pipe pile is high in corrosion resistance, good in durability and higher in flexural rigidity than a spiral steel pile, and the part exposed out of the ground can bear horizontal loads transmitted from the upper portion and bending moment from the upper portion; the spiral steel pile is arranged on the lower portion, the shear strength of a pile-soil interface is improved through the mechanical meshing effect between the blades and the soil body, and the unique advantages of the spiral pile in the anti-pulling engineering are fully played.
本发明属于土木工程技术领域，具体涉及一种用于光伏支架的PHC管桩与螺旋钢桩组合桩基础，组合桩基础由底板、加劲肋、PHC管桩、PHC管桩端板、钢管桩、螺旋叶片和桩尖组成；螺旋叶片焊接在钢管桩的外表面上，PHC管桩端板焊接在钢管桩的顶端，PHC管桩焊接在PHC管桩端板上，底板焊接在PHC管桩的顶端，桩尖焊接在钢管桩的底端，加劲肋焊接在底板的底面和钢管桩的外表面上。PHC管桩抗腐蚀性强、耐久性良好，而且抗弯刚度比螺旋钢桩大，露出地面部分还能承受上部传来的水平荷载及上部弯矩；下部为螺旋钢桩，通过叶片与土体之间的机械咬合作用提升了桩—土界面的抗剪强度，并充分发挥螺旋桩在抗拔工程中有独特的优势。
