Abstract

Disclosed is a construction method of a drilling and pressing pouring concrete carrier pile. The pile hole forming steps of the existing static force extrusion concrete carrier pile construction method are improved to change the static force hole forming into the drilling by a twist drill, that is, the twist drill installed in a pile machine is used to drill holes. Because of the adoption of the invention, while drilling holes by using the twist drill, the soil in the hole is carried to the ground in the pile hole drilling process of the invention, the foundation surrounding the pile hole can not be extruded, so the foundation between the pile holes can not be bulged by extrusion, and the subsequent construction can not be influenced.

Description

The job practices of drilling and pressing precast concrete carrier pile
Technical field
The present invention relates to construction work underpin technology, especially the job practices of concrete perfusion carrier pile consolidated subsoil.
Background technology
The construction of the concrete perfusion carrier pile of existing consolidated subsoil, in order to reduce noise and vibrations interference and influence to the people around the construction plant, adopt the job practices of static(al) extruding, patent document CN1837505A discloses a kind of like this method, this method needs to utilize the pressure of the static pressure oil cylinder of hydraulic press to be pressed in the ground simultaneously the casing of pipe and outer tube in the having on the stake machine in construction, mention interior pipe then, concrete perfusion carrier pile in the pore outside, because in implementing this procedure, need the interior pipe and the outer tube of casing are pressed into ground, therefore the ground around the stake hole that extrudes be squeezed and to around displacement, if the perfusion carrier pile is more in the ground, extruded ground will upwards swell between the stake hole, thereby causes ground to be uneven, and influences follow-up construction.
Summary of the invention
For overcome existing concrete perfusion carrier pile the deficiency of job practices, the invention provides a kind of job practices of drilling and pressing precast concrete carrier pile, change the way of static pressure pore-forming in the work progress, adopt the auger rotary drilling, can not produce extruding, just can not make upwards protuberance of ground yet the ground around the stake hole.
The job practices of drilling and pressing precast concrete carrier pile provided by the invention comprises: form the stake hole in ground; In the stake hole, insert and manage in the having of stake machine and the casing of outer tube; Mention interior pipe, outside the casing pack masonry; Depress interior pipe, the masonry in the extruding outer tube makes in the ground of outer tube bottom and forms the masonry enlarged footing; Mention interior pipe, in outer tube, place reinforcing cage, concrete perfusion; Concrete spouting withstands concrete with interior pipe after specifying absolute altitude, mention outer tube, finishes the making of concrete carrier pile; And form the stake hole in this job practices in ground is to realize by such step: use the auger that is installed on the machine to hole on ground and simultaneously the earth in the hole is taken to ground, mention drilling tool behind the auger drilling to completion, form the stake hole in the ground.
The invention has the beneficial effects as follows: take the earth in the hole to ground when forming the stake hole with the rotary drilling on ground of the auger on the stake machine, ground around the stake hole is not squeezed, just can not be subjected to displacement, the ground between the stake hole can not swell yet, and follow-up construction is unaffected.
Description of drawings
Fig. 1 is construction sequence of the present invention and implements device structure schematic diagram of the present invention.
In Fig. 1, a. is drilled to a hole with the auger that is installed on the machine in ground, and b. mentions auger, move the stake machine, insert interior pipe, the outer tube of stake machine casing in the stake hole, c. mentions interior pipe, outside the casing pack masonry, d. make in the ground of outer tube bottom with the masonry in the interior pipe extruding outer tube and form the masonry enlarged footing, e. mention interior pipe, place reinforcing cage, concrete perfusion in outer tube, f. withstands concrete with interior pipe, mention outer tube, make the concrete perfusion carrier pile; 1. the sliding bolt mechanism that connects lamination shoe on the stake machine frame, 2. lamination shoe, the 3. sliding bolt mechanism of connection auger, 4. a machine, 5. auger on the machine frame, 6. stake hole, 7. outer tube, 8. in pipe, 9. masonry, 10. masonry enlarged footing, 11. reinforcing cages, 12. concrete, 13. concrete carrier piles.
The specific embodiment
Consult Fig. 1 embodiments of the present invention be described, may further comprise the steps:
A. on ground, get out a hole 6 at stake machine 4 places in place with the auger 5 that is installed on the machine 4; B. mention auger 5, move stake machine 4, in stake hole 6, insert interior pipe 8, the outer tube 7 of stake machine casing; C. pipe 8 in mentioning, filling masonry 9 in outer tube 7; D. make with the masonry 9 in the interior pipe 8 extruding outer tubes 7 and form masonry enlarged footing 10 in the outer tube 7 bottom grounds; E. pipe 8 in mentioning is placed reinforcing cage 11, concrete perfusion 12 in outer tube 7; F. withstand concrete 12 with interior pipe 8, pull up outer tube 7, make concrete perfusion carrier pile 13.

Claims (1)

1, a kind of job practices of drilling and pressing precast concrete carrier pile comprises: form the stake hole in ground; In the stake hole, insert and manage in the having of stake machine and the casing of outer tube; Mention interior pipe, outside the casing pack masonry; Depress interior pipe, the masonry in the extruding outer tube makes outer tube bottom ground form the masonry enlarged footing; Mention interior pipe, in outer tube, place reinforcing cage, concrete perfusion; Concrete spouting withstands concrete with interior pipe after specifying absolute altitude, mention outer tube, finishes the making of concrete carrier pile; It is characterized in that forming the stake hole in this job practices in ground is to realize by such step: use the auger that is installed on the machine on ground, to hole and take the earth in the hole to ground simultaneously, mention drilling tool behind the auger drilling to completion, form the stake hole in the ground.
