Ultra-long prestressed pipe pile limiting and hydraulic punch hammer pile sinking method in complex sea reclamation land area
The invention relates to the technical field of pile sinking methods, and discloses a complex sea reclamation land area ultra-long prestressed pipe pile limiting and hydraulic punch hammer pile sinking method which comprises the steps that a construction site is leveled, a pile position is measured, a pile sinking limiting frame is arranged, a hoop is arranged on the pile sinking limiting frame, and a hollow area is formed in the hoop; the center of the hollow area and the center of the pile position are arranged in an up-down alignment mode; the super-long prestressed pipe pile is hoisted through a crane and penetrates through the hollow area of the hoop, and the hoop surrounds the super-long prestressed pipe pile so that the super-long prestressed pipe pile can be relatively fixed; the hydraulic impact hammer is lifted to the top of the super-long prestressed pipe pile through the crane, the super-long prestressed pipe pile is impacted through the hydraulic impact hammer, and the super-long prestressed pipe pile gradually sinks into the stratum; and after the super-long prestressed pipe pile sinks into the stratum by a set depth, the hoop loosens the super-long prestressed pipe pile, and the hydraulic impact hammer continuously impacts the super-long prestressed pipe pile until the super-long prestressed pipe pile sinks into the stratum by a required depth. Therefore, the effects of reliable quality and efficient construction are achieved.
本发明涉及沉桩方法的技术领域，公开了复杂填海陆域区超长预应力管桩限位与液压冲锤沉桩方法，包括平整施工场地以及测定桩位，布置沉桩限位架，沉桩限位架上设有抱箍，抱箍中具有中空区域，将中空区域的中心与桩位的中心呈上下对齐布置；利用吊车将超长预应力管桩起吊并将其穿过抱箍的中空区域，抱箍环抱着超长预应力管桩使其相对固定；利用吊车起吊液压冲击锤至超长预应力管桩的顶部，利用液压冲击锤冲击超长预应力管桩，超长预应力管桩逐渐沉入地层中；当超长预应力管桩沉入地层设定深度后，抱箍松开对超长预应力管桩的环抱，液压冲击锤继续冲击超长预应力管桩，直至超长预应力管桩沉入地层中要求深度。这样，具有质量可靠、施工高效的效果。
