Girdling splitting type integral pile breaking method
The invention discloses a girdling splitting type integral pile breaking method. The method comprises the steps that 1, rebars, extending into a pile head, of a reinforcement cage are all sleeved with PVC-U plastic pipes before pipe breaking; 2, the pile head is broken. The pile head breaking process comprises the steps of 1, measuring the elevation of the top of a pile, and making a girdling line mark; 2, conducting girdling for a circle with a small cutter on the girdling line mark; 3, drilling two holes in two positions symmetrical about the elevation of the top of the pile; 4, inserting two hydraulic splitting machines into the holes for splitting; 5, hoisting pile head concrete out. The inner diameter of each PVC-U plastic pipe is 1.2-1.3 times of the diameter of each rebar, the diameter of each hole is 40 mm, and the depth of each hole is 200 mm. By the adoption of the method, pile foundation rebars are neat, the pile head is flat, favorable conditions are created for follow-up construction, the quality of the pile head is guaranteed, construction efficiency is improved, and labor intensity is relieved greatly.
