Abstract
The utility model discloses a prestressed steel pipe-concrete pipe pile, which comprises a steel pipe, the outer wall of the steel pipe is covered by a concrete layer, a plurality of angle irons are evenly and circumferentially arranged on the outer wall of the steel pipe in the concrete layer, the length direction of the angle iron accords with the axial direction of the steel pipe, and moreover, the angle irons are surrounded by a steel wire along the circumference of the steel pipe. In the pipe pile disclosed by the utility model, the angle irons are arranged around the outer wall of the steel pipe to enhance the bending resistance and strike resistance of the pipe pile, meanwhile, the steel wire circumferentially surrounding the angle irons can effectively enhance the firmness of the concrete layer and the combination between the concrete layer and the steel pipe, consequently, an engineering pipe pile with performance close to the performance of the pipe pile can be obtained with low cost, and the application range of the prestressed steel pipe-concrete pipe pile is greatly broadened.
Description
Technical field
The utility model relates to a kind of concrete tubular pile, relates in particular to a kind of prestressing steel pipe concrete pipe pile.
Background technology
In the existing Industrial and Civil Engineering pile foundation of China, adopt the pile foundation of prestressed concrete pipe pile or steel pipe pile in a large number.But because the mechanical property of prestressed concrete pipe pile or steel pipe pile and cost of investment etc. are former thereby influence its use.
In the pile foundation of bridge, port works, some can adopt the pile foundation of prestressed concrete pipe pile as carrying, but because the bending resistance moment of prestressed concrete pipe pile is less, the bearing capacity bent a little less than, concrete tubular pile is worn a layer ability in addition, can not enter the rock stratum, and abandon selecting prestressed concrete pipe pile, then select steel pipe pile.
The requirement for bearing capacity to stake is not high in the Equipment Foundations of some engineerings on land, the pile foundation that adopts prestressed concrete pipe pile or thin steel pipe pile to do carrying just can satisfy requirement for bearing capacity, but to having relatively high expectations of pile sinking, Zhuan durable resistance can not meet the demands again like this, so, transfer to select steel pipe pile again.
Under above-mentioned two kinds of situations, though but select the steel pipe pile engineering demands, also caused the significantly raising of engineering cost.
The utility model content
The utility model provides a kind of prestressing steel pipe concrete pipe pile at the drawback of prior art.
Prestressing steel pipe concrete pipe pile described in the utility model, comprise the steel cylinder pipe, described steel cylinder pipe outer wall oversite concrete layer, steel cylinder pipe outer wall in the described layer of concrete a plurality of angle steel that are uniformly distributed along the circumference, described angle steel length direction and steel cylinder tubular axis be to identical, and described a plurality of angle steel by steel wire along steel cylinder pipe circumferencial direction around.
In the prestressing steel pipe concrete pipe pile described in the utility model, by establishing angle steel at steel cylinder pipe outer wall ring to strengthen the flexing resistance and the durable resistance of pile tube, simultaneously, on the angle steel circumferencial direction around steel wire can well strengthen layer of concrete soundness and with the associativity of steel cylinder pipe, make at lower cost with regard to the engineering tubular pile of availability near steel pipe pile, the range of application of having widened prestressing steel pipe concrete pipe pile greatly.
Description of drawings
Fig. 1 is the structural representation of prestressing steel pipe concrete pipe pile described in the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail, can implements according to this with reference to the manual literal to make those skilled in the art.
As shown in Figure 1, prestressing steel pipe concrete pipe pile described in the utility model, comprise steel cylinder pipe 4, described steel cylinder pipe 4 outer wall oversite concrete layers 1, steel cylinder pipe 4 outer walls in the described layer of concrete 1 a plurality of angle steel 3 that are uniformly distributed along the circumference, described angle steel 3 length directions are axially identical with steel cylinder pipe 4, and described a plurality of angle steel 3 by steel wire 2 along steel cylinder pipe 4 circumferencial directions around.Described steel wire 2 around angle steel 3 should extend to identical with the length of angle steel 3 at least, thereby it is netted to make angle steel 3 and steel wire 2 be woven in whole layer of concrete 1, with this strengthen layer of concrete 1 fastness and with the compactness of steel cylinder pipe 4.
In the utility model, described angle steel 3 along the outer wall circumference uniform distribution of steel cylinder pipe 4 12, this angle steel quantity can be selected flexibly according to concrete application scenario.
In the prestressing steel pipe concrete pipe pile described in the utility model, by establishing angle steel at steel cylinder pipe outer wall ring to strengthen the flexing resistance and the durable resistance of pile tube, simultaneously, on the angle steel circumferencial direction around steel wire can well strengthen layer of concrete soundness and with the associativity of steel cylinder pipe, make at lower cost with regard to the engineering tubular pile of availability near steel pipe pile, the range of application of having widened prestressing steel pipe concrete pipe pile greatly.
Although embodiment of the present utility model is open as above, but it is not restricted to listed utilization in manual and the embodiment, it can be applied to the various fields of the present utility model that are fit to fully, for those skilled in the art, can easily realize other modification, therefore under the universal that does not deviate from claim and equivalency range and limited, the legend that the utility model is not limited to specific details and illustrates here and describe.
