Construction method of assembly type deep foundation pile
The invention discloses a construction method of an assembly type deep foundation pile. The construction method comprises the following steps of (1) in-place, specifically, pile work equipment is moved, and double sleeves are positioned on a set pile position; (2) pipe sinking, specifically, the double sleeves are sunk to a set depth; (3) feeding and pouring; and (4) expanding the bottom. According to the construction method of the assembly type deep foundation pile, a double-sleeve equipment device is improved, and the length of the inner pipe can be changed by adopting different sections according to conditions; the inner pipe can be used as a force transmission rod part, a power rod part and a feeding channel at the same time; and the inner pipe can be hammered into a hole, moreover, the double sleeves are reversely inserted and sunk into an expanded head to form an expansion head anchor rod, and a new generation of compression-resistant and pulling-resistant expanded bore piles (including a rammed-expanded pile, a full rammed pile, an inner rammed pile and a static-pressure expanded bore pile) are formed.
本发明公开了一种装配式深基础桩的施工方法，包括下列步骤：（一）就位：移动桩工设备，将双套管就位于设定桩位上；（二）沉管：将双套管沉管至设定深度；（三）投料灌注；（四）扩底。本发明改进了双套管设备装置，内管长度可以根据情况采用不同节数，实现长度可变；内管即可做传力杆件，又可作动力杆件，同时可作为投料通道；既可以锤击出孔，也可以双套管反插下沉入扩大头内，形成扩大头锚杆，形成新一代抗压抗拔扩底桩（包括夯扩桩、全夯桩、内夯桩、静压扩底桩）。
