Abstract
The invention discloses an inner-tamping, pipe-immersing poured and tamp-expanded pile construction method, comprising the steps of moving and spotting machine, forming by tamp-expansion, pouring molding, pipe drawing forming, etc. And it has characters of low construction noise, little environmental influence, good environmental protectiveness, reliable construction quality and good pile body quality.
Description
Technical field:
The present invention relates to a kind of job practices.
Background technology:
The form that the construction technology of existing tube-sinking cast-in-situ pile, compaction pile generally adopts diesel hammer or vibrating hammer directly to hit the outer tube inner tamping tube, its construction noise is big, and vibration is big, and is bigger to the influence of surrounding environment, has some undesirable parts.
Summary of the invention:
The object of the present invention is to provide a kind of construction noise little, little to ambient influnence, the feature of environmental protection is good, the job practices of the internal-tamping immersed tube bored concrete tamping-extending pile of reliable construction quality.
Technical solution of the present invention is:
A kind of job practices of internal-tamping immersed tube bored concrete tamping-extending pile is characterized in that: comprise the following steps:
(1) telephone-moving is in place: mobile device is located in outer tube on the setting stake position;
(2) immersed tube: outer tube is sunk down into set depth;
(3) ram to expand moulding: on carry interior hammer ram in the outer tube, once throw in the outer tube by the setting height H that feeds intake, on pull out outer tube certain altitude h, interior hammer ram is rammed inserts repeatedly and is formed enlarged footing, by adjusting size, the shape that shape factor α=h/H wherein adjusts tamper diffusion head, α value (0,1) wherein;
(4) build moulding: on carry interior hammer ram, build pile body or transfer precast pile;
(5) tube drawing moulding: extract outer tube, forming pile.
Immersed tube method in the step (2) is:
(a) ram the soil body in: the interior hammer ram in the outer tube is mentioned do the movement of falling object, the soil body under the punching outer tube forms soil body sheared edge;
(b) outer tube sinks: outer tube adopts one of following method to sink at least: 1. under the outer tube deadweight, outer tube sinks from gravity along soil body sheared edge; 2. start the water booster system on the outer tube, outer tube sinks along the pressurization of soil body sheared edge; 3. start the vibrating device on the outer tube, outer tube is along soil body sheared edge vibration-sunk; 4. start vibration and water booster system on the outer tube simultaneously, outer tube along soil body sheared edge shake depress heavy;
(c) mutual (a) and (b) step sinks down into set depth until outer tube.
Immersed tube method in the step (2) is: bury shoe underground in the outer tube bottom, adopt external force that outer tube is sunk down into set depth simultaneously.
Construction noise of the present invention is little, little to ambient influnence, and the feature of environmental protection is good, reliable construction quality, and pile quality is good.
The invention will be further described below in conjunction with embodiment.
