Abstract
The utility model discloses a concrete pipe pile which comprises a pipe wall formed by an inner surface and an outer surface, wherein a reinforcing steel bar strengthening piece is arranged in the pipe wall. The concrete pipe pile is characterized in that spiral bulges are coaxially formed around the outer surface. The concrete pipe pile has the advantages that the concrete pipe pile is convenient for construction, the friction force between the concrete pipe pile and soil mass is increased, and the bearing capacity and the stability are improved.
Description
Technical field
The utility model relates to a kind of building pile tube, especially relates to a kind of concrete tubular pile.
Background technology
Concrete tubular pile is adopted in foundation engineering widely.The profile of traditional concrete tubular pile is generally linear pattern, the shortcoming of this pile tube be and the soil body between frictional force less, when needs satisfy larger bearing capacity, often need to increase 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 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, disclose a kind of prestressed concrete pipe pile such as the Chinese invention patent application Publication Specification that on March 11st, 2009, disclosed publication number was CN 101381992A, be cylinder, 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.Although this design can improve the contact area between pile tube and the soil body to a certain extent, increasing friction force, shortcoming is need to apply larger vertical forces to pile tube when piling construction, and is high to the piling equipment requirement, also increased the piling difficulty simultaneously.
Summary of the invention
The concrete tubular pile that frictional force between that technical problem to be solved in the utility model provides a kind of constructability and the soil body increases.
The utility model solves the problems of the technologies described above the technical scheme that adopts: a kind of concrete tubular pile, comprise the tube wall that is surrounded by inner surface and external surface, and be provided with steel reinforcing spare in the described tube wall, be 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 helical raised.
Preferably, described helical raised is discontinuous helical raised.
Preferably, evenly have a plurality of grooves on the described helical raised, described groove is divided into described helical raised the segment at several intervals along the spiral trend.
Preferably, observe from cross section, the above the quantity of groove of each circle projection of described helical raised is six ~ 40.
Compared with prior art, the utility model has the advantage of: the external surface of the utility model concrete tubular pile is coaxially arranged with helical raised, impose torsion when when piling applies vertical forces to pile tube, the helical raised of formation is conducive to carrying out smoothly of the process of driving piles; The design of helical raised increases the surface area of pile tube, and the increase of the contact area between the soil body, so the frictional force between pile tube and the soil body increases the supporting capacity of pile tube and stable the raising; When on helical raised, evenly having a plurality of groove, these grooves are divided into helical raised the segment at several intervals, this moment, thereby this discontinuous helical raised further increased between pile tube and the soil body in the frictional force at further increase pile tube surface area, reduce the pile tube materials, alleviate the pile tube deadweight.
