Abstract
The invention discloses a concrete pipe pile which comprises a pipe wall formed by an inner surface and an outer surface in surrounding manner. Reinforcement members are disposed in the pipe wall. The concrete pipe pile is characterized in that spiral projections are coaxially arranged around the outer surface. The concrete pipe pile has the advantages that the concrete pipe pile is convenient to construct, the friction of the concrete pipe pile with soil mass is increased, and bearing capacity and stability of the concrete pipe pile are improved.
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, comprises the tube wall surrounded by inner surface and external surface, is provided with steel reinforcing part in described tube wall, is coaxially arranged with helical raised around described external surface.
Preferably, the helical angle of described helical raised is 30 ° ~ 87 °.
Preferably, described helical raised is continuous print helical raised.
Preferably, described helical raised is discontinuous helical raised.
Preferably, described helical raised evenly has multiple groove, described helical raised is divided into the segment at several intervals by described groove along spiral trend.
Preferably, observe from cross section, the quantity of the protruding described groove of each circle of described helical raised is six ~ 40.
Compared with prior art, the invention has the advantages that: the external surface of concrete tubular pile of the present invention is coaxially arranged with helical raised, impose torsion while applying vertical forces when driving piles to pile tube, the helical raised of formation is conducive to carrying out smoothly of piling process; The design of helical raised makes the surface area of pile tube increase, and the contact area between the soil body increases, and the frictional force therefore between pile tube and the soil body increases, and the supporting capacity of pile tube and stability improve; When helical raised evenly has multiple groove, helical raised is divided into the segment at several intervals by these grooves, now this discontinuous helical raised is further increasing pile tube surface area thus to increase between pile tube and the soil body while frictional force further, reduce pile tube materials, alleviate pile tube deadweight.
