Abstract

The utility model discloses a glass-fiber reinforced polypropylene (FRPP) steel-strip-wound ribbed pipe, which comprises a cylindrical pipe wall made of FRPP, wherein a reinforcing rib is wound on the outer surface of the cylindrical pipe wall and comprises an FRPP layer and a steel strip; the section of the steel strip is T-shaped; the steel strip comprises a vertical section and a horizontal section; the vertical section is arranged in the FRPP layer; and the horizontal section is arranged in the cylindrical pipe wall. According to the FRPP steel-strip-wound ribbed pipe provided by the utility model, the T-shaped steel strip is arranged in the reinforcing rib to enhance the strength of the FRPP steel-strip-wound ribbed pipe, that is, the overall strength is increased by several times or even dozens of times. During the process of connection of two pipes, when a bulldozer is adopted for backfilling, the FRPP steel-strip-wound ribbed pipes receive an external pressure which is applied from the top down and perpendicular to the excircles of the cylindrical pipe walls, and as the T-shaped steel strips are perpendicular to the excircles of the cylindrical pipe walls, most of the external pressure acts on the T-shaped steel strips, so that the pipes are not likely to deform.

See also Fig. 1, existing FRPP polypropylene strengthens riffled tube and comprises cylindric tube wall 100, is provided with at cylindric tube wall 100 outer surfaces to be the stiffening rib 110 that ripple twines shape.This tubing in order to reduce labor intensity, generally is to adopt the bulldozer backfill to replace artificial backfill in actual connection procedure, and compacting or roll, and in this process, the connection mouth place of tubing is crushed easily, and What is more, can cause breaking of tubing connection mouth.
In view of this, nowadays in the urgent need to designing a kind of novel fiber glass reinforced polypropylene steel strip winding riffled tube, with the performance of further raising riffled tube.
The model utility content
Technical problem to be solved in the utility model is: a kind of fiber glass reinforced polypropylene steel strip winding riffled tube is provided, can further improve the intensity of riffled tube, and not yielding.
For solving the problems of the technologies described above, the utility model adopts following technological scheme:
A kind of fiber glass reinforced polypropylene steel strip winding riffled tube, described riffled tube comprise the cylindric tube wall that fiber glass reinforced polypropylene FRPP material is made, and are wound with stiffening rib at described cylindric tube wall outer surface; Described stiffening rib comprises FRPP material layer and steel band, and the section of steel band is " T " font; Described steel band comprises vertical section, horizontal segment, and vertical section is arranged in the FRPP material layer, and horizontal segment is arranged in the cylindric tube wall.
As a kind of preferred version of the present utility model, described FRPP material layer and cylindric tube wall fit tightly.
As a kind of preferred version of the present utility model, the vertical section of described steel band is perpendicular to cylindric tube wall setting, that is: the center line of vertical section and cylindric tube wall have a joint in the steel band section, described cylindric tube wall outer surface has one along the tangent plane of this joint, the center line of vertical section is vertical with this tangent plane in the described steel band section, and the section of steel band refers to the cross section perpendicular to the steel strip winding trend.
As a kind of preferred version of the present utility model, the vertical section of described steel band and horizontal segment integrated setting.
The beneficial effects of the utility model are: the fiber glass reinforced polypropylene FRPP steel strip winding riffled tube that the utility model proposes, by " T " font steel band is set in stiffening rib, strengthened the intensity of FRPP steel strip winding riffled tube, bulk strength has increased several times even tens times.In two pipeline connection procedures, when adopting the bulldozer backfill, FRPP steel strip winding riffled tube is subject to the external pressure perpendicular to cylindric tube wall cylindrical from top to bottom, because the steel band of " T " font is vertical with the cylindrical of cylindric tube wall, the external pressure major part acts on the steel band of this " T " font, thereby so that tubing (the especially mouth of pipe) is not easy distortion.
In addition, under with the ring stiffness level, the needed raw material of the utility model riffled tube reduce, and the steel band cost is low, has reduced cost of production.Under with the ring stiffness level, the utility model riffled tube overall weight alleviates, and has reduced transportation and lifting cost and has used.The utility model mainly serves as buried drain pipe.

Embodiment
Describe preferred embodiment of the present utility model in detail below in conjunction with accompanying drawing.
Embodiment one
See also Fig. 2, the utility model has disclosed a kind of fiber glass reinforced polypropylene steel strip winding riffled tube, and described riffled tube comprises the cylindric tube wall 100 that fiber glass reinforced polypropylene FRPP material is made, and is wound with stiffening rib 110 at described cylindric tube wall outer surface.The inner wall smooth of cylindric tube wall, resistance is little, and charge species can not be attached to and form incrustation scale on the tube wall in the water.Fiber glass reinforced polypropylene FRPP steel strip winding riffled tube has corrosion-resistant, resistant to elevated temperatures characteristics.
Described stiffening rib 110 comprises FRPP material layer 130 and steel band 120, and described FRPP material layer 130 fits tightly with cylindric tube wall 100.The section of steel band 120 is " T " font; Described steel band 120 comprises vertical section 121, horizontal segment 122, and vertical section 121 is arranged in the FRPP material layer 130, and horizontal segment 122 is arranged in the cylindric tube wall 100.In the present embodiment, the vertical section 121 of described steel band 120 and horizontal segment 122 integrated setting can improve compressive strength; Certainly, the vertical section 121 of steel band 120 and horizontal segment 122 can not be integral structures also.
