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 adopted in foundation engineering widely.The profile of traditional concrete pile tube is generally linear pattern, the shortcoming of this pile tube be and the soil body between frictional force less, when needs satisfy bigger bearing capacity, often need increase the length or the quantity of pile tube, this can increase the cost of whole pile foundation engineering.In order to increase the frictional force between the pile tube and the soil body, improve the supporting capacity of pile tube, people have done the improvement of many aspects to concrete tubular pile; Chinese invention patent Shen Qing Publication manual as on March 11st, 2009, disclosed publication number was CN 101381992A discloses a kind of prestressed concrete pipe pile, is cylinder, and the centre is hollow; Comprise tube wall; In the outer circumference surface design gear shape structure of tube wall, with the surface area of raising pile tube, and then the supporting capacity of raising pile tube.Though this design can improve the contact area between the pile tube and the soil body to a certain extent, increase frictional force, shortcoming is when piling construction, need apply bigger vertical forces to pile tube, and is high to the piling equipment requirements, also increased the piling difficulty simultaneously.
Summary of the invention
Technical problem to be solved by this invention provides the concrete tubular pile that the frictional force between a kind of that be convenient to construct and soil body increases.
The present invention solves the problems of the technologies described above the technical scheme that is adopted: a kind of concrete tubular pile; Comprise the tube wall that surrounds by inner surface and external surface; Be provided with steel reinforcing spare in the described tube wall; There is the gear-like that is parallel to each other of many astragals double wedge protruding around the coaxial regularly vertically distributed and arranged of described external surface; The quantity of the double wedge on described each circle gear-like convexity is at least six, the described double wedge that respectively encloses on the gear-like convexity evenly distribute and the quantity of described double wedge identical; With a circle gear-like convexity topmost is that the first lap gear-like is protruding, observes from top to bottom, protruding since the second circle gear-like, and each circle gear-like convexity is rotated the identical anglec of rotation that staggers around the central axis of pile tube to same direction successively.
Preferably, the direction that staggers around the central axis rotation of pile tube successively of described each circle gear-like convexity is for clockwise or counterclockwise.
Preferably, the quantity of the double wedge on described each circle gear-like convexity is smaller or equal to 40.
Preferably, the angle of the described anglec of rotation is less than the angle of the protruding adjacent two double wedge centreline spaces of described 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 that the is parallel to each other convexity of many astragals double wedge vertically; With the top one circle gear-like convexity is that the first lap gear-like is protruding; Observe from top to bottom, protruding since the second circle gear-like, each circle gear-like convexity is rotated the identical anglec of rotation that staggers around the central axis of pile tube to same direction successively; Like this; From the external surface of whole pile tube, form the gear-like that the is parallel to each other convexity of many astragals double wedge at the external surface of pile tube, and respectively enclose the protruding teeth groove of gear-like and stagger each other; See that from top to bottom respectively enclosing the gear-like convexity constitutes the spiral helicine teeth groove band of a rule around the central axis of pile tube to the stagger teeth groove of an identical anglec of rotation of same direction rotation; Each encloses the gear-like convexity and constitutes the spiral helicine double wedge band of a rule around the central axis of pile tube to the stagger double wedge of an identical anglec of rotation of same direction rotation, imposes torsion when when piling, pile tube being applied vertical forces, and the helical form teeth groove band of formation and double wedge have and be beneficial to carrying out smoothly of piling process; While is because helical form teeth groove band and double wedge band have increased the contact area of the pile tube and the soil body, so the frictional force between the pile tube and the soil body increases the supporting capacity of pile tube and stability raising.
