Abstract
The invention provides a prestressed concrete pipe pile. The prestressed concrete pipe pile comprises a steel cylinder tube and is characterized in that a steel fiber reinforced concrete layer is arranged on the inner wall of the steel cylinder tube, the outer wall of the steel cylinder tube is covered with a concrete layer, a plurality of steel angles are evenly distributed on the circumferential surface of the outer wall of the steel cylinder tube inside the concrete layer, the height direction of the steel angles is the same as the axial direction of the steel cylinder tube, the steel angles are encircled by steel wires in the circumferential direction of the steel cylinder tube, the outer side of the concrete layer is covered with a cement mortar protection layer, and the surface of the cement mortar protection layer is coated with a polyethylene anticorrosive coating. The steel angles are T-shaped steel angles which are used for enhancing the bending resistance and impact resistance of the pipe pile. The steel wires encircling the steel angles in the circumferential direction can greatly strengthen solidity of the concrete layer and the combinability between the steel angles and the steel cylinder tube. The surface of the cement mortar protection layer is coated with the polyethylene anticorrosive coating, so the anticorrosive and sealing performance can be enhanced, and the application range of the prestressed concrete pipe pile is greatly broadened. The prestressed concrete pipe pile is high in waterproofness, stable in quality, convenient to construct, high in applicability and free of environment pollution.
Description
Technical field
The present invention relates to building field, relate 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, and the mechanical performance that it is good and easily manufacturing process 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 abnormal occasion of some acid-base value; although the outermost layer of prestressed concrete pipe pile is coated with cement mortar protective course; but still be difficult to guarantee that, after 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 subject to curved bearing capacity a little less than; in addition concrete tubular pile is worn a layer ability, can not enter rock stratum.
Summary of the invention
In order to solve the problems of the technologies described above; the invention provides a kind of prestressed concrete pipe pile; comprise steel cylinder pipe; it is characterized in that described steel cylinder inside pipe wall arranges steel fibrous concrete layer; described steel cylinder pipe outer wall oversite concrete layer; steel cylinder pipe outer wall in 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 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 layer of polyethylene corrosion-inhibiting coating.
Described angle steel is T font angle steel.
Described angle steel number is N, N >=8.
Beneficial effect of the present invention is: at steel cylinder pipe outer wall ring, establish T shape angle steel to strengthen flexing resistance and the durable resistance of pile tube; simultaneously; on angle steel circumferencial direction around steel wire can well strengthen layer of concrete soundness and with the associativity of steel cylinder pipe; make with regard to availability, to approach at lower cost the engineering tubular pile of steel pipe pile; surface at cement mortar protective course applies layer of polyethylene corrosion-inhibiting coating; can greatly strengthen preserving and sealing, thus the range of application of having widened prestressed concrete pipe pile.Water proofing property of the present invention is strong, steady quality, easy construction, applicability are strong, free from environmental pollution.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
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 present invention 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 wall in 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 make angle steel 4 and steel wire 5 in whole layer of concrete 3, be woven into netted, with this strengthen layer of concrete 3 fastness and with the compactness of steel cylinder pipe 1.At the outside one deck cement mortar protective course 6 that covers of layer of concrete 3, on cement mortar protective course 6 surfaces, be coated with layer of polyethylene corrosion-inhibiting coating 7, can strengthen greatly preserving and sealing, thus the range of application of having widened prestressed concrete pipe pile.
