Abstract
The invention relates to a bearing pile used in a foundation of a construction such as civil engineering, building and the like. The bearing pile comprises a lower pile tube, the lower pile tube consists of a tube body and a spiral cutter, the tube body and the spiral cutter form a whole cast at one time, and the lower pile tube is made of nodular cast iron. The lower pile tube made of the nodular cast iron is provided with the spiral cutter, and the lower pile tube is screwed into the soil by adopting a special piling machine to increase the bearing capacity of the foundation. The bearing pile has the performance of intrinsic steel of iron, meanwhile, has good corrosion resistance, does not need anticorrosion treatment, and has low production cost and long service life.
Description
Technical field
The present invention relates to the bearing pile that uses in the basis of structures such as building, building.
Background technology
In the soft foundation of civil work of ground was constructed, often adopting concrete prefabricated stake or steel pipe to drive piles increased the supporting capacity on basis.Concrete prefabricated stake intensity difference, and steel pipe easily gets rusty, application life is low.
Summary of the invention:
In order to overcome the shortcoming of prior art, the invention provides a kind of piling pipe, it has the performance of the essential steel of iron, while corrosion resistance and good, long service life.
The present invention solves the technical scheme that its technical problem takes: it comprises following pipe, and following stake pipe is made up of body 3 and circular knife 4, and body 3 and circular knife 4 are whole of once-cast, and the material of following pipe is a ductile iron.
It also comprises the stake pipe, forms by body 1 and bellmouth 2, and the upper end that can insert a described following pipe in the bellmouth 2, the material of last stake pipe is a ductile iron.
The following pipe racks of ductile iron of the present invention has circular knife, adopts special-purpose pile driver that following pipe screwed in the soil vertically downward, cooperates when the degree of depth is not enough to go up the use of stake pipe.Simultaneously corrosion resistance and good need not to do preservative treatment, and cost of production is low, and long service life is 2～3 times of steel pipe.
Description of drawings
The present invention is further described below in conjunction with accompanying drawing.
Accompanying drawing is a structural representation of the present invention.
The specific embodiment
As shown in drawings, the present invention includes down the stake pipe, following stake pipe is made up of body 3 and circular knife 4, and body 3 and circular knife 4 are whole of once-cast, and material is a ductile iron.
It also comprises the stake pipe, is made of the upper end that can insert a described following pipe in the bellmouth 2 body 1 and bellmouth 2.
Upper and lower stake pipe adopts the water-cooled spun casting.Following stake length of tube is generally 6 meters, can cooperate the stake pipe to use together when screw-in depth is not enough, and last stake is managed and can the scene be joined brill with a following pipe and be connected.
Claims (2)
1. a piling is managed, and it is characterized in that: it comprises following pipe, and following stake pipe is made up of body (3) and circular knife (4), and body (3) and circular knife (4) are whole of once-cast, and the material of following stake pipe is a ductile iron.
2. piling pipe according to claim 1 is characterized in that: it also comprises the stake pipe, form by body (1) and bellmouth (2), and the upper end that can insert a described following pipe in the bellmouth (2), the material of last stake pipe is a ductile iron.
