Variable axial force pile and mounting method thereof
The invention discloses a variable axial force pile and an installation method thereof.The variable axial force pile comprises a pressure disc, a bent pressing rod, a constraint cable, a common steel bar, a permanent anchoring support, a post-grouting pipeline, pile body concrete and other structures, and the pressure disc can be divided into a full-pile pressure upper disc, a full-pile pressure lower disc, a local pressure upper disc and a local pressure lower disc according to installation parts; the restraining cables are divided into full-pile restraining cables and local restraining cables, the buckling rod supports are evenly distributed on the four sides of the bottom of the local pressure upper disc and the four sides of the top of the local pressure lower disc, the buckling rod supports are hinged to the buckling edge rods, the buckling edge rods can rotate around the buckling supports, and the middle buckling rod is arranged between the two buckling edge rods. And the bending edge rods and the bending middle rod are hinged. According to the variable axial force pile, the tension of the pile body can be converted into the pressure of the pile body through the pressure disc and the restraint cable, the material characteristic that the concrete of the pile body is high in pressure resistance is fully played, the concrete of the variable axial force pile body is pressed, tension cracks are avoided, and the durability of the pile is improved.
本发明公开了一种变轴力桩及其安装方法，包括压力盘、压曲杆、约束索、普通钢筋、永久锚固支座、后压浆管道和桩身混凝土等结构，压力盘以安装部位划分可以分为全桩压力上盘、全桩压力下盘、局部压力上盘、局部压力下盘，约束索分为全桩约束索和局部约束索，压曲杆支座均匀分布在局部压力上盘的底部四侧和局部压力下盘的顶部四侧，压曲杆支座与压曲边杆铰接，压曲边杆可以环绕压曲支座转动，两个压曲边杆之间设置有压曲中杆，压曲边杆和压曲中杆之间铰接。本发明变轴力桩通过压力盘和约束索，可以将桩身拉力转换桩身压力，充分发挥了桩身混凝土抗压能力强的材料特性，变轴力桩身混凝土受压，避免产生拉裂缝，提高了桩的耐久性。
