Embodiment Construction

[0024] A pile construction method comprising

[0025] (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 ;

[0026] (2) Immersed tube: sink the immersed tube system of the equipment to the set depth;

[0027] (3) Pouring: lift up the internal ramming pipe system, pour the pile body or lower the prefabricated pile body;

[0028] (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;

[0029] The immersed tube system in step (1) is a single-steel outer tube with a set rigid...

Abstract

The invention discloses a pile construction method. The pile construction method comprises a placing step and a tube sinking step; a tube sinking method comprises the following steps: starting inner tubes in a pressurizing and static pressure system and a tube sinking system of pile working equipment; performing interactive pressurization and internal ramming; sinking the tube sinking system to a set depth. The pile construction method has the advantages of improving the tube sinking technique and the feeding technique and improving the work efficiency, and is a new pile construction technology which is controllable in process and reliable in quality.

Description

technical field [0001] The invention relates to a pile construction method. Background technique [0002] The existing construction techniques of static pressure cast-in-place piles, prefabricated piles, bottom-expanded piles, and composite piles, among them, sinking pipe pile technology, bottom-expanding technology, feeding technology, and core-inserting pile technology need to be improved, and the work efficiency needs to be improved. [0003] The existing pile driver has a maximum pile pressing force of 1,200 tons (self-weight + counterweight), a maximum pile pulling force of 800 tons, and a maximum full load of 1,200+800=2,000 tons, which is difficult to meet the construction requirements in general sites. Contents of the invention [0004] The object of the present invention is to provide a construction method of piles with convenient construction and less counterweight of pile drivers. [0005] Technical solution of the present invention is: [0006] A construction...
