Abstract
The utility model provides a prestressed concrete pipe pile. The prestressed concrete pipe pile comprises a steel cylinder pipe and is characterized in that a steel fiber concrete layer is arranged on the inner wall of the steel cylinder pipe, the outer wall of the steel cylinder pipe is covered by a concrete layer, and much angle iron is evenly distributed on the outer wall of the steel cylinder pipe inside the concrete layer and along the periphery of the outer wall of the steel cylinder pipe, wherein the height direction of the angle iron is as same as the axial direction of the steel cylinder pipe, the much angle iron is surrounded by steel wires along the periphery direction of the steel cylinder pipe, the outside of the concrete layer is covered by a cement mortar protective layer, and the surface of the cement mortar protective layer is coated by a polyethylene anticorrosive coating layer. The angle iron is T-shaped in order to reinforce buckling resistance and beating resistance of the pipe pile, the steel wires surrounded along the periphery direction of the angle iron can well reinforce solidity of the concrete layer and combinability of the concrete layer and the steel cylinder pipe, the polyethylene anticorrosive coating layer coated on the surface of the cement mortar protective layer can improve antiseptic and sealing performance, and greatly broaden application ranges of the concrete pipe pile. The prestressed concrete pipe pile is good in water-proof performance, stable in quality, convenient to construct, good in applicability and free of polluting environment.
Description
Technical field
The utility model relates to building field, relates in particular to a kind of prestressed concrete pipe pile.
Background technology
In the existing Industrial and Civil Engineering pile foundation of China, adopt in a large number the pile foundation of prestressed concrete pipe pile or steel pipe pile.But because the mechanical property of prestressed concrete pipe pile or steel pipe pile and cost of investment etc. are former thereby affect its use.
Application for prestressed concrete pipe pile is comparatively extensive, the mechanical performance that it is good and easily manufacturing process make it become the constructional materials of all kinds of building first-selections.This prestressed concrete pipe pile is when going deep into ground; circumstance complication of living in; especially in the unusual occasion of some acid-base value; although the outermost layer of prestressed concrete pipe pile is coated with cement mortar protective course; but still after being difficult to guarantee the several years, this cement mortar protective course is destroyed, cause the performance of this prestressed concrete pipe pile to be affected and bending resistance moment is less, be subjected to curved bearing capacity a little less than; concrete tubular pile is worn a layer ability in addition, can not enter the rock stratum.
Summary of the invention
In order to solve the problems of the technologies described above; the utility model provides a kind of prestressed concrete pipe pile; comprise the steel cylinder pipe; it is characterized in that described steel cylinder inside pipe wall arranges the steel fibrous concrete layer; 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 short transverse is axially identical with the steel cylinder pipe; and described a plurality of angle steel by steel wire along steel cylinder pipe circumferencial direction around; the outside one deck cement mortar protective course that covers of described layer of concrete, described cement mortar protective course surface is coated with the layer of polyethylene corrosion-inhibiting coating.
Described angle steel is T font angle steel.
Described angle steel number is N, N 〉=8.
The beneficial effects of the utility model are: establish T shape angle steel to strengthen flexing resistance and the durable resistance of pile tube at steel cylinder pipe outer wall ring; 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; so that at lower cost with regard to the engineering tubular pile of availability near steel pipe pile; surface at cement mortar protective course applies the layer of polyethylene corrosion-inhibiting coating; can greatly strengthen preserving and sealing, thus the range of application of having widened prestressed concrete pipe pile.The utility model water proofing property is strong, steady quality, easy construction, applicability are strong, free from environmental pollution.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Wherein, 1-steel cylinder pipe, 2-steel fibrous concrete layer, 3-layer of concrete, 4-angle steel, 5-steel wire, 6-cement mortar protective course, 7-polyethylene anticorrosion coating.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail;
As shown in Figure 1, at steel cylinder pipe 1 inwall steel fibrous concrete layer 2 is set, steel cylinder pipe 1 outer wall oversite concrete layer 3, steel cylinder pipe 1 outer walls in the described layer of concrete 38 the T font angle steel that are uniformly distributed along the circumference, to strengthen flexing resistance and the durable resistance of pile tube, angle steel 4 short transverses are axially identical with steel cylinder pipe 1, and 8 T font angle steel 4 by steel wire 5 along steel cylinder pipe 1 circumferencial direction around, angle steel 4 by steel wire 5 along steel cylinder pipe 1 circumferencial direction around, thereby it is netted to make angle steel 4 and steel wire 5 be woven in whole layer of concrete 3, with this strengthen layer of concrete 3 fastness and with the compactness of steel cylinder pipe 1.At the layer of concrete 3 outside one deck cement mortar protective courses 6 that cover, be coated with layer of polyethylene corrosion-inhibiting coating 7 on cement mortar protective course 6 surfaces, can strengthen greatly preserving and sealing, thus the range of application of having widened prestressed concrete pipe pile.
