Abstract
The invention discloses an FRPP (fiber reinforced polypropylene) steel-belt-wound ribbed tube and a preparation method thereof. The ribbed rube comprises a cylindrical tube wall manufactured by adopting an FRPP material, wherein a reinforcing rib formed by jointly winding a steel belt and an FRPP material is wound on the outer surface of the cylindrical tube wall and comprises an FRPP material layer and the steel belt in the FRPP material layer; the cross section of the steel belt is I-shaped; and the steel belt is arranged perpendicularly to the outer surface of the cylindrical tube wall. The FRPP steel-belt-wound ribbed tube has the advantages that through arranging the steel belt of which the cross section is I-shaped in the reinforcing rib, the strength of the FRPP steel-belt-wound ribbed tube is enhanced and the integral strength is increased by several times or even dozens of times; during the connection process of two tubes, when soil is backfilled by adopting a soil shifter, the FRPP steel-belt-wound ribbed tube is subjected to top-down external pressure perpendicular to an excircle of the cylindrical tube wall, and since the I-shaped steel belt is perpendicular to the excircle of the cylindrical tube wall, most of the external pressure acts on the I-shaped steel belt, so the tubular product is not easy to deform.
