Abstract
The utility model discloses an FRPP (fiber reinforced poly propylene) dual-wall steel strip wound ribbed pipe. The FRPP dual-wall steel strip wound ribbed pipe comprises a barrel-shaped inner wall made from glass FRPP, wherein a reinforced rib is wound on the outer surface of the inner wall of the barrel-shaped inner wall to form a corrugated outer wall; the reinforced rib comprises an FRPP layer and angle steel in the FRPP layer; the cross section of the angle steel is V-shaped; and the arrangement direction of the angle steel is that an opening faces to the barrel-shaped inner wall. According to the FRPP dual-wall steel strip wound ribbed pipe, the V-shaped angle steel is arranged in the reinforced rib, so that the strength of the wound ribbed pipe is improved and the overall strength is improved by multiple times and even dozens of times. In the process of connecting two pipelines, when a bulldozer is adopted to perform the refilling operation, the FRPP dual-wall steel strip wound ribbed pipe receives external pressures perpendicular to the outer circle of the barrel-shaped pipe wall from top down, and most of the external pressures act on the V-shaped angle steel as the opening of the V-shaped angle steel faces to the barrel-shaped inner wall, so that the pipe is not easily deformed.

In view of this, nowadays in the urgent need to designing a kind of novel FRPP double-walled 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 FRPP double-walled 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 FRPP double-walled steel strip winding riffled tube, described riffled tube comprises the cylindric inwall of fiber glass reinforced polypropylene FRPP material, is wound with stiffening rib at described cylindric inboard wall outer surface, forms the corrugated outer wall; Described stiffening rib comprises the angle steel in FRPP material layer and the FRPP material layer, and the section shape of described angle steel is " V " font, and the setting party of angle steel is to being that opening is towards described cylindric inwall.
As a kind of preferred version of the present utility model, in the axial cross section of described riffled tube, the corrugated outer wall is corrugated.
As a kind of preferred version of the present utility model, the intimate of described FRPP material layer and cylindric inwall is fitted, the outer surface of the whole cylindric inwall of FRPP layer of material covers.
As a kind of preferred version of the present utility model, described corrugated outer wall also comprises the FRPP packed layer that is arranged between the adjacent rebar element except comprising the stiffening rib that is wound in cylindric inboard wall outer surface; Described rebar element is one section stiffening rib in cylindric one week of inboard wall outer surface of continuous winding.
As a kind of preferred version of the present utility model, the intimate of described FRPP packed layer and cylindric inwall is fitted.
As a kind of preferred version of the present utility model, the FRPP material layer of described corrugated outer wall, FRPP packed layer integrated molding.
The beneficial effects of the utility model are: the FRPP double-walled steel strip winding riffled tube that the utility model proposes, by " V " font angle steel is set, strengthened the intensity of twining riffled tube in stiffening rib, and 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 opening of the angle steel of " V " font is towards described cylindric inwall, the external pressure major part acts on the angle steel of this " V " 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 angle steel 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.
