Abstract
The utility model relates to an external anti-corrosion structure for a prestressed hollow square pile. The external anti-corrosion structure mainly comprises the prestressed hollow square pile which is provided with a center through hole in the center along the length direction thereof, and the through hole penetrates the whole prestressed hollow square pile. The cross section of the outer circumference of the prestressed hollow square pile is square. The prestressed hollow square pile mainly comprises a reinforcement cage, a concrete layer and end plates. The reinforcement cage is composed of a plurality of main reinforcing ribs and stirrups. The main reinforcing ribs are distributed along the length direction of the prestressed hollow square pile, and the stirrups are spirally wound around the main reinforcing ribs. The concrete layer coats the reinforcement cage inside, and the cross section of the entire concrete layer is square. The end plates are respectively arranged at two ends of the concrete layer, and an anti-corrosion structure is arranged on the outer surface of the concrete layer. The external anti-corrosion structure for the prestressed hollow square pile has the advantages that the outer surface of the prestressed hollow square pile is coated with an anti-corrosion paint layer which can effectively protect the prestressed hollow square pile and prevent the same from being corroded by the stratum.
Description
Technical field
The utility model relates to a kind of external pre-stress hollow square pile anticorrosion structure, a kind of pre-stress hollow square pile that can improve the pre-stress hollow square pile antiseptic property specifically.
Background technology
The pre-stressed concrete hollow square stake is a kind of elongated square-outside and round-inside uniform section precast unit that professional factory adopts technologies such as pretensioned prestressing, centrifugal forming and stream curing to make, and is transported to the soil spreading and sinks to the underground basis that becomes building.Its stratum that is suitable for is that stream is moulded, the soft foundation of soft-plastic state, and bearing stratum is preferably argillic horizon, layer of sand, buried basement rock, and severely-weathered rock stratum or weathering remain the stratum of thicker soil, is particularly useful for the thicker ground of soft layer.
And at present, the pre-stress hollow square pile in use the existing market, it is after implanting the stratum, after after a while, the stratum can be gradually the whole hollow square pile of corrosion from outside to inside, in the application life of having reduced hollow square pile, also can cause certain potential safety hazard simultaneously.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of pre-stress hollow square pile that can improve the pre-stress hollow square pile antiseptic property.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: mainly comprise a pre-stress hollow square pile;
Have a central through hole that runs through whole pre-stress hollow square pile at the pre-stress hollow square pile center along described pre-stress hollow square pile length direction, the periphery cross section of described pre-stress hollow square pile is square;
Described pre-stress hollow square pile mainly comprises reinforcing cage, layer of concrete and end plate, reinforcing cage is made up of around stirrup two parts of described main muscle some main muscle and spirals that extend along the hollow square pile length direction, in described layer of concrete is wrapped in reinforcing cage, and the cross section of monolithic concrete layer is square-shaped, and described end plate is separately positioned on the two ends of layer of concrete;
The external surface of described layer of concrete is provided with anticorrosion structure.
Further, described anticorrosion structure is specially: layer of concrete is provided with one deck corrosion resistant coating along the external surface of four faces of the width of pre-stress hollow square pile.
Further, the cross section of described central through hole can rounded shape, also can be square-shaped.
Advantage of the present utility model is: four external surfaces at pre-stress hollow square pile scribble one deck corrosion resistant coating, after hollow square pile is implanted the stratum, utilize corrosion resistant coating can slow down the stratum to the corrosion of hollow square pile, improve the application life of hollow square pile.
Description of drawings

Fig. 2 is the lateral view of external pre-stress hollow square pile anticorrosion structure of the present utility model.
The specific embodiment
By schematic diagram shown in Figure 1 as can be known, external pre-stress hollow square pile anticorrosion structure of the present utility model is mainly a pre-stress hollow square pile.
By schematic diagram shown in Figure 2 as can be known, pre-stress hollow square pile mainly comprises reinforcing cage, layer of concrete 4 and end plate 3 three parts, reinforcing cage mainly is made up of main muscle 1 and stirrup 2 two parts, main muscle 1 has some, length direction along pre-stress hollow square pile extends, and all main muscle 1 evenly distribute round the circumferencial direction of pre-stress hollow square pile, stirrup 2 integral body are shape in the shape of a spiral, and be rotated winding round all main muscle 1, in layer of concrete 4 is wrapped in whole reinforcing cage, and whole layer of concrete 4 is rectangular structure, the cross section of layer of concrete 4 is square-shaped, end plate 3 is separately positioned on the two ends of layer of concrete 4, and the external surface of layer of concrete 4 is provided with anticorrosion structure.
Anticorrosion structure is specially: on the external surface of four faces of the width of pre-stress hollow square pile, scribble one deck corrosion resistant coating 8 at layer of concrete 4 uniformly, and corrosion resistant coating 8 the most at last the external surface of four faces of identical four faces one of end plate 3 and layer of concrete 4 and layer of concrete 4 all cover.
Be provided with a central through hole 5 in the center of pre-stress hollow square pile, central through hole 5 runs through whole pre-stress hollow square pile along the pre-stress hollow square pile length direction, the periphery cross section of pre-stress hollow square pile is square, the cross section of central through hole 5 also is square, and each bar seamed edge 6 of the cross section of square central through hole 5 equates that with distance between the seamed edge of end plate 3 angle between every adjacent two seamed edges 6 is arc chord angle 7.
The cross section of the central through hole 5 in the present embodiment also can rounded shape, and the center of the cross section of the center of circle of the cross section of central through hole 5 and end plate 3 is same point.
