[0029] A pile construction method comprising
[0030] (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 ;
[0031] (2) Immersed tube: sink the immersed tube system of the equipment to the set depth;
[0032] (3) Pouring: lift up the internal ramming pipe system, pour the pile body or lower the prefabricated pile body;
[0033] (4) Tube extraction: for prefabricated piles: pull out the outer tube, fill the gap around the precast pile with filler and curing agent, and the pile is formed; for cast-in-place piles: pull out the outer tube, and the reinforced concrete pile is formed; It is also possible not to pull out the outer pipe, and form the steel pipe concrete pile;
[0034] The immersed tube system in step (1) is a single-steel outer tube with a set rigid...
