Description
Technical field
The present invention relates to a kind of building pile tube, especially relate to a kind of concrete tubular pile.
Background technology
Concrete tubular pile is widely adopted in foundation engineering.The profile of traditional concrete tubular pile is generally linear pattern, and the shortcoming of this pile tube is that the frictional force between the soil body is less, and when the bearing capacity that demand fulfillment is larger, often need the length or the quantity that increase pile tube, this can increase the cost of whole pile foundation engineering.In order to increase the frictional force between pile tube and the soil body, improve the supporting capacity of pile tube, people have done to be permitted many-sided improvement to concrete tubular pile, disclosed in 11 days March in 2009, publication number is that the Chinese invention patent application Publication Specification of CN 101381992A discloses a kind of prestressed concrete pipe pile, and in cylinder, centre is hollow, comprise tube wall, in the outer circumference surface design gear shape structure of tube wall, to improve the surface area of pile tube, and then improve the supporting capacity of pile tube.Although this design can improve the contact area between pile tube and the soil body to a certain extent, increasing friction force, shortcoming needs when piling construction to apply larger vertical forces to pile tube, high to piling equipment requirement, too increases piling difficulty simultaneously.
Summary of the invention
The concrete tubular pile that technical problem to be solved by this invention is to provide a kind of constructability and frictional force between the soil body increases.
The present invention solves the problems of the technologies described above adopted technical scheme: a kind of concrete tubular pile, comprise the tube wall surrounded by inner surface and external surface, steel reinforcing part is provided with in described tube wall, around described external surface vertically regularly coaxial distribution to be provided with the gear-like be parallel to each other of multi-turn band double wedge protruding, the quantity of the double wedge in each described circle gear-like projection is at least six, and the double wedge in described each circle gear-like projection is uniformly distributed and the quantity of described double wedge is identical; Observe from top to bottom for first lap gear-like projection so that topmost a circle gear-like is protruding, from the second circle gear-like is protruding, each circle gear-like projection rotates in the same direction around the central axis of pile tube the identical anglec of rotation that staggers successively.
Preferably, each described circle gear-like projection is clockwise or counterclockwise successively around the direction of the central axis rotational offset of pile tube.
Preferably, the quantity of the double wedge in each described circle gear-like projection is less than or equal to 40.
Preferably, the angle of the described anglec of rotation is less than the angle of the described protruding adjacent two double wedge centreline spaces of each circle gear-like.
Preferably, the angle of the described anglec of rotation is 1 ° ~ 30 °.
Preferably, the angle of the described anglec of rotation is 3 ° ~ 15 °.
Compared with prior art, the invention has the advantages that: the external surface of concrete tubular pile of the present invention is provided with the gear-like the be parallel to each other projection of multi-turn band double wedge vertically, so that topmost a circle gear-like is protruding for first lap gear-like projection, observe from top to bottom, from the second circle gear-like is protruding, each circle gear-like projection rotates in the same direction around the central axis of pile tube the identical anglec of rotation that staggers successively, like this, from the external surface of whole pile tube, the gear-like be parallel to each other forming multi-turn band double wedge at the external surface of pile tube is protruding, and the teeth groove of each circle gear-like projection staggers mutually, see that the teeth groove that the protruding central axis around pile tube of each circle gear-like rotates in the same direction the identical anglec of rotation that staggers forms the spiral helicine teeth groove band of a rule from top to bottom, the double wedge that the protruding central axis around pile tube of each circle gear-like rotates in the same direction the identical anglec of rotation that staggers forms the spiral helicine double wedge band of a rule, torsion is imposed while vertical forces being applied to pile tube when driving piles, the helical form teeth groove band formed and double wedge band are conducive to carrying out smoothly of piling process, simultaneously because helical form teeth groove band and double wedge band increase the contact area of pile tube and the soil body, the frictional force therefore between pile tube and the soil body increases, and the supporting capacity of pile tube and stability improve.
