Embodiment Construction

[0031] A construction method for piles, comprising the steps of:

[0032] (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 ;

[0033] (2) Immersed tube: press the immersed tube system of the equipment to sink to the set depth;

[0034] (3) Pouring: lift up the internal ramming pipe system, pour the pile body or lower the prefabricated pile body;

[0035] (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;

[0036] 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;

Abstract

The invention discloses a construction method for a pile. The construction method comprises the steps of in place, pipe sinking, pouring, pipe drawing and the like. According to the construction method, construction is simple, and the effect is good; and a feed process, a pipe sinking process and a base expansion process are improved, and timeliness and work efficiency are improved. Static pressure, hammering, an inner rammer cast-in-place pile and an enlarged toe pile can be constructed. The static pressure, the hammering, an inner rammer composite pile, the enlarged toe pile and other pipe types can be achieved. The construction method is an environmentally friendly, flow-controllable and quality-ensured novel technology for static pressure, hammering, and inner rammer piles.

Description

technical field [0001] The invention relates to a pile construction method. Background technique [0002] Among the existing construction techniques of static pressure sinking pipe grouting piles, prefabricated piles, bottom expansion piles, and composite piles, the technology of sinking pipe piles, bottom expansion technology, feeding technology, and core insertion pile technology needs to be improved, and the timeliness and work efficiency need to be improved. . Contents of the invention [0003] The object of the present invention is to provide a construction method of piles with convenient construction and good effect. [0004] Technical solution of the present invention is: [0005] A pile construction method is characterized in that: comprising the following steps: [0006] (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 t...
