Construction method for hoisting and aligning super-long prestressed pipe pile to pile position
The invention relates to the technical field of super-long prestressed pipe pile hoisting, and discloses a super-long prestressed pipe pile hoisting and pile position aligning construction method which comprises the steps that a pile sinking limiting frame is arranged, a plurality of hoops are arranged on the pile sinking limiting frame, hollow areas are formed in the hoops, a crane is arranged, and a main lifting hook and an auxiliary lifting hook are arranged on the crane. The main lifting hook is connected with a main sling through a main lifting rope; the auxiliary lifting hook is connected with an auxiliary sling through an auxiliary lifting rope; the super-long prestressed pipe pile is horizontally hoisted to a hoisting area, the main lifting hook is pulled, the auxiliary lifting hook is stopped from being pulled until the super-long prestressed pipe pile is hoisted to be in a vertical shape, then the super-long prestressed pipe pile penetrates through the hollow areas of the multiple hoops, the pile sinking limiting frame is adjusted, and the super-long prestressed pipe pile is hoisted to be in a vertical shape. And after the center of the super-long prestressed pipe pile and the center of the pile position are aligned up and down, the main lifting hook is released to lift the super-long prestressed pipe pile. Therefore, the super-long prestressed pipe pile can be lifted to a set position, and meanwhile, the perpendicularity of the super-long prestressed pipe pile can be effectively controlled in the pile sinking process through the hoop.
本发明涉及超长预应力管桩起吊的技术领域，公开了超长预应力管桩起吊对准桩位施工方法，包括布置沉桩限位架，沉桩限位架上设有多个抱箍，抱箍中具有中空区域，布置吊车，吊车上设有主吊钩以及副吊钩，主吊钩通过主吊绳连接有主吊索，副吊钩通过副吊绳连接有副吊索；将超长预应力管桩呈水平状吊至吊装区，并通过收拉主吊钩，停止收拉副吊钩，直至超长预应力管桩起吊呈垂直状，再将超长预应力管桩穿过多个抱箍的中空区域，调节沉桩限位架，直至超长预应力管桩的中心与桩位的中心呈上下对齐布置后，松开主吊钩对超长预应力管桩的起吊。这样，即可将超长预应力管桩起吊至设定位置，同时通过抱箍可有效的控制沉桩过程中，超长预应力管桩的垂直度。
