Abstract

Disclosed is a glass fiber reinforced plastic corrugated pipe. The glass fiber reinforced plastic corrugated pipe comprises an inside liner, an inner structural layer, a sand adding layer, an outer structural layer with reinforced ribs, and a plastic film layer, wherein the inside liner, the inner structural layer, the sand adding layer, the outer structural layer with the reinforced ribs and the plastic film layer are sequentially arranged from the inside to the outside. The outer structural layer with the reinforced ribs is composed of a plurality of glass fiber bundle winding layers which are provided with resin in a soaking mode and a spiral reinforced rib which is clamped among the plurality of winding layers, wherein the reinforced rib is a thick string which is in a screw thread type and is formed in a twisting mode by glass fiber bundles provided with the resin in a soaking mode. According to the glass fiber reinforced plastic corrugated pipe, a layer of screw-thread-type glass fiber bundles which are used as the reinforced rib are added in the outer structural layer on the traditional glass fiber reinforced plastic sand pipeline, the external surface of the whole pipeline is of a corrugated structure, and thus not only can structural strength of the corrugated pipe be increased, but also particularly cross sectional moment of inertia and ring crush resistance are enhanced, and therefore load intensity of the corrugated pipe can be increased so that pipeline applied ranges are enlarged. In addition, cost of the glass fiber reinforced plastic corrugated pipe is lower than that of a steel tube, however, weight of the glass fiber reinforced plastic corrugated pipe is merely 1/4 of that of the steel tube, and thereby the glass fiber reinforced plastic corrugated pipe is extremely competitive in the market.
