Abstract
The utility model relates to a high-water-content soil texture pore-forming pile pipe which is characterized in that a cover plate is arranged at the upper end opening of a pipe body in a sealed way, the lower end of the pipe body is a tapered pile tip part, the pile tip part is connected with the pipe body by a locking mechanism, a plurality of air exhausting holes are arranged on the pile tip part, and air inlet holes are arranged at the upper section of the pipe body. When the pore-forming operation on a high-water-content soil texture foundation is carried out, resistance-free sinking of a pile pipe can be ensured, an air channel passing through an inner cavity of the pile pipe is also formed, so that the air exhausting is smooth when the pile pipe is lifted, and the smooth lifting of the pile pipe can be realized; meanwhile, the scraping and the rubbing of a hole wall are eliminated, fall back soil in the pile pipe is limited to be lower than 200mm, the requirement of standard design is achieved, and the follow up multiple repeated soil-pulling-out operations are avoided. The high-water-content soil texture pore-forming pile pipe is suitable for the pore-forming operation of the pile pipes with various diameters.
Description
Technical field
The utility model relates to the pore-forming apparatus that a kind of building lot is handled usefulness, specifically a kind of high moisture soil property pore-forming stake pipe.
Background technology
In architectural process, ground is handled the job practices that is adopted, and mainly contains CFG castinplace pile, 37 lime earth compaction pile composite foundation, these three kinds of forms of deposited reinforced concrete pile.In the drilling construction process in all kinds of stakes hole, because used pore-forming equipment---the structure of stake pipe is unreasonable, in pore forming process with and subsequent stake pipe lifting process in, the capital constantly scrapes a topsoil of hole inwall, thereby in the sinking process of stake pipe and in the lifting process of stake pipe, produce a lot of falling soil at stake Kong Zhonghui, increased follow-up repetition soil digging operation repeatedly.
The utility model content
The purpose of this utility model just provides a kind of high moisture soil property pore-forming stake pipe, falls the more problem of soil after rise to solve drilling construction process king-pile hole.
The utility model is achieved in that a kind of high moisture soil property pore-forming stake pipe, upper port at body is sealed with cover plate, the lower end of body is the stake tip of taper, institute's improvements are, described stake tip is connected by blocking mechanism with described body, have the plurality of rows pore in described stake tip, have air inlet at the epimere of described body.
Described steam vent has 2-4, is uniformly distributed along the circumference in described stake tip.
The utility model is offered air inlet by the body epimere at the stake pipe, offers steam vent in the stake tip, thereby forms a kind of fenestration stake pipe.Use this fenestration stake pipe, when on the moisture earthen foundation of height, carrying out the pore-forming operation, both can guarantee that the non-resistance of a pipe sank, a gas circuit by the stake tube cavity can be provided again, solved thus when pulling out on the stake pipe and formed vacuum, the problem that causes a pipe to be difficult to extract in bottom, stake hole.Owing to cancelled the reinforced steel bar ring of original evagination in the stake pipe, correspondingly eliminated the scratch of reinforced steel bar ring to hole wall, it is minimum that the falling soil in a hole is reduced to, and generally can be limited in below the 200mm, reached the requirement of design specifications.
The utility model can guarantee a hole depth when utilizing the stake pipe to be carried out to hole operation, improve construction speed, has reduced a large amount of falling soil that form behind tube drawing, has avoided follow-up repeatedly repetition soil digging operation.The pile tube that the utility model is suitable for various diameters becomes hole operation.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, body 3 is the cylindrical steel tubular structure, is sealed with cover plate 2 in the upper port of body 3, and the lower end of body 3 is the tapered pile tip 4 of 60 ° of angles.Stake tip 4 is flexible connection with body 3, so that in time remove the hack that enters in the pipe behind tube drawing.Stake tip 4 realizes flexibly connecting by blocking mechanism with body 3, and blocking mechanism can be various known connected modes such as hook structure or key structure.
Have 2-4 steam vents 5 in stake tip 4, steam vent 5 is uniformly distributed along the circumference on the stake tip.Epimere at body 3 has air inlet 6.Air inlet can be square hole or circular hole, and the diameter of circular hole gets final product about 100mm.
During use, the stake pipe is perpendicular to ground, and pile monkey 1 back and forth falls from the top, impacts on cover plate 2, and the stake pipe is constantly sunk and pore-forming; After putting in place, pinion cover plate 1 with wire rope, on carry a pipe and portal, finish into hole operation; Then, open blocking mechanism, after disposing the hack in the body 1 and resetting, promptly be transferred to next position, hole, proceed into hole operation.
Claims (2)
1. one kind high moisture soil property pore-forming stake pipe, upper port at body (3) is sealed with cover plate (2), the lower end of body (3) is the stake tip (4) of taper, it is characterized in that, described stake tip (4) is connected by blocking mechanism with described body (3), have plurality of rows pore (5) in described stake tip (4), have air inlet (6) at the epimere of described body (3).
2. the moisture soil property pore-forming of height according to claim 1 stake pipe is characterized in that described steam vent (5) has 2-4, is uniformly distributed along the circumference in described stake tip (4).
