Reinforced concrete and glass fiber reinforced plastic sand inclusion composite pipes and molding process thereof

Abstract

The invention discloses a composite tube of steel bar concrete and glass fiber reinforced plastic sand inclusion and a forming technique thereof. The composite tube is compounded by the glass fiber reinforced plastic sand inclusion tube and inorganic steel bar concrete. The forming technique adopts that the glass fiber reinforced plastic sand inclusion tube is laid on a mandrel of a mandrel vibration forming machine and is connected with a precast connecting pin, a vertical annular convex and concave steel bar frame and a steel bar frame; then the forming machine is started and filled with concrete material; the composite tube is formed, ejected and maintained to produce the composite tube of the invention. The product of the invention has the advantages of good anticorrosive performance, bright and clean inner wall, small flow resistance, fast speed, high strength, non-deformation, low cost, good quality and long service life.

Description

technical field [0001] The invention relates to an urban basic building component, in particular to a reinforced concrete and glass fiber reinforced plastic sand composite pipe and a forming process thereof. Background technique [0002] The traditional wound FRP sand pipe is used for large pipes and pipe jacking. It has been proved by many years of practice that its anti-corrosion performance is good, the inner wall of the pipe is smooth, which reduces the resistance of the liquid flow rate and increases the liquid flow rate, but the disadvantage is that it has poor compressive strength and is easy to deform. . The traditional reinforced concrete pipes are used for large pipes and jacking pipes, which have good strength and no deformation, but poor anti-corrosion performance, and the inner wall is not smooth and clean, which increases the flow resistance. Therefore, the technical performance and product quality of the above-mentioned two traditional products and their appl...
