Embodiment Construction

[0027] A construction method for piles, comprising the steps of:

[0028] (1) Placement: place the immersed tube system of the equipment on the set pile position, or near the pile position that has been constructed, or in the center of the cement-soil pile position that has been constructed; pile shoes can be pre-embedded on the pile position ;

[0029] (2) Immersed tube: sink the immersed tube system of the equipment to the set depth;

[0030] (3) Pouring: lift up the internal ramming pipe system, pour the pile body or lower the prefabricated pile body;

[0031] (4) Pulling out the tube: pull out the outer tube, fill the gap around the prefabricated pile with filler and curing agent, and the pile is formed;

[0032] The immersed tube system in step (1) is a single-steel outer tube with a set rigidity, a single-steel inner rammed tube and a connecting device; the outer diameter of the inner rammed tube is smaller than the inner diameter of the outer tube;

[0033] Step (2) ...
