Abstract
The invention provides a foundation pile, relating to the foundation pile which is used under bridges and buildings. The foundation pile in the invention is composed of a pile body and a bidirectionalmulti-level jack, wherein, the pile body is in a cylinder shape and the lower part is in a conical shape; and the lower part of the pile body is provided with one to a plurality of bidirectional multi-level jack and the installation angles thereof are staggered mutually. When in use, the bidirectional multi-level jacks are recoiled inside the pile body; the pile body is driven underground througha pile driver, and then a hydraulic pump leads the bidirectional multi-level jack to push out of the pile body and stretch into a foundation layer laterally. By utilizing the bidirectional multi-level jack, the foundation pile expands the contact area between the foundation pile and the foundation, thus having stronger compressive resistance and pull-out resistance; in addition, the foundation pile has simple construction, reliable performance, no earth volume and no pollution, and can greatly reduce the number of piling and construction volume and reduce cost effectively.
Description
Technical field
A kind of foundation pile relates to the foundation pile that uses under bridge and the building.
Background technology
The foundation pile that uses under bridge or building at present mostly is the cylindrical shape piling bar.The surface of cylindrical shape piling bar is smooth, and is little with the friction of ground, thereby its resistance to compression and uplift resistance are all smaller.In order to overcome this point deficiency, just need to beat a plurality of stakes and overcome.Will strengthen construction volume and cost like this.
Summary of the invention
The purpose of this invention is to provide all foundation piles preferably of a kind of resistance to compression uplift resistance.
Foundation pile of the present invention is made of pile body and two-way multistage jack; Pile body is a cylindrical shape, and the bottom is conical; Be equipped with 1 to several two-way multistage jack in the bottom of pile body, its setting angle staggers mutually.
During use, two-way multistage jack contracts in pile body.Earlier pile body is driven underground by pile driver, then,, makes two-way multistage jack eject pile body, extend transversely in the ground layer by hydraulic pump.
This foundation pile has enlarged the contact area of foundation pile and ground, thereby has had stronger resistance to compression uplift resistance owing to used two-way multistage jack.In addition, this foundation pile construction is simple, dependable performance, no earth volume, pollution-free, can reduce piling number and construction volume greatly, has effectively reduced cost.
Description of drawings
Fig. 1 is the schematic diagram of this foundation pile;
Generalized section when Fig. 2 is two-way multistage jack withdrawal;
Generalized section when Fig. 3 stretches out for two-way multistage jack.
The specific embodiment
Foundation pile of the present invention is made of pile body 1 and two-way multistage jack 2; Pile body 1 is a cylindrical shape, and the bottom is conical; In the bottom of pile body 12 to 4 two-way multistage jack 2 are housed, its setting angle staggers mutually.Two-way multistage jack 2 is made of the movable oil cylinder 5,6 of shell 3 and two groups of symmetries; Have hydraulic oil inlet 4 at the middle part of shell; Movable oil cylinder 5,6 is divided into three grades, is sleeved on together, and symmetrical is contained in the shell 3.
