Technical Field

The utility model relates to a plastics drain pipe, concretely relates to take plastic steel pipe of axial strengthening rib.

Background

As shown in fig. 1, the plastic-steel pipe is structured by first extruding a continuous strip of plastic wrapped with one or more reinforcing ribs, then spirally winding the strip by a special forming mechanism, wherein the winding pitch is generally smaller than the width of the strip, so that lap joints are generated in the width direction of the strip, hot melt adhesive is extruded by an extruder to bond the lap joints of the strip together, and the plastic-steel pipe is formed by continuously repeating the winding and the lap joints. After the reinforcing metal strip wrapped by the plastic on the winding strip is spirally wound, a spiral reinforcing structure is formed on the surface of the pipe, and the reinforcing structure is perpendicular to the axial direction of the pipe. Although the reinforcing structure can improve the ring stiffness of the pipe, in the production, transportation and construction processes of the pipe, when the reinforcing structure perpendicular to the axial direction is subjected to the moment in the axial direction of the pipe, the reinforcing structure is easy to collapse and deflect, so that the reinforcing effect is influenced, and even the pipe is broken, so that the reliability and the service life of the pipe are influenced.
