The material of external protection can adopt glass fibre reinforced plastic material, thermoplastic material or resin mortar, and the external protection outer surface carries out press polish to be handled.
The innermost layer of composite pipe is the frp lining layer, and the frp lining layer has constituted the smooth inner wall of multiple tube, has the function of anti-corrosion leak-proof simultaneously.The frp lining layer is outward the glass fibre reinforced plastic structure layer, the glass fibre reinforced plastic structure layer provides a part of intensity, and the glass fibre reinforced plastics socket that form to connect at the socket end, the groove of placing rubber ring and the pressure testing hole that is used for water pressure testing can be set on the glass fibre reinforced plastics socket as required, and the inside part structure of bellmouth adopts glass fibre reinforced plastic material to make; Simultaneously except that the socket end, all scribble the resin quartz sand particle, as the junction surface that combines with concrete structure in its outside.The used glass fibre reinforced plastics of frp lining layer and glass fibre reinforced plastic structure layer is reinforcing material with glass fibre and fabric thereof, is that body material adopts winding process to be made with the unsaturated polyester resin.
By the punching block instillation process cement stone sand slurry is poured in the glass fibre reinforced plastics cylinder body outer wall and forms the concrete structure layer, its structure characteristics is: concrete and glass fibre reinforced plastic structure layer outer wall particle transition layer form the junction surface of combining closely, concrete in addition aquation is shunk, and makes concrete and glass fibre reinforced plastic structure layer form tight composite structure.The concrete pipe construction layer mainly provides the rigidity of pipeline.
The outer wall of concrete pipe structure twines reinforcement wire; and mainly hold interior laminated structure as pipeline; reinforcement wire is closely wrapped up by outer protective material, and the material of external protection can adopt glass fibre reinforced plastic material, thermoplastic material or resin mortar, is used for preventing the corrosion of steel wire burn into.
The utility model had both been avoided the shortcoming of traditional concrete pipe, Prestressed concrete cylinder pipe and fiber reinforced plastic pipe, combined the advantage of traditional piping material again, mainly had the following advantages:
1, combines the intensity of reinforcement wire and glass fibre reinforced plastics, have very high hoop tensile strength, can bear the interior pressure of pressing very much;
2, make full use of the characteristics of the high rigidity of concrete, can bear high external pressure;
3, give full play to the ganoid characteristics of frp lining, have good hydraulic performance;
4, the corrosion resistant characteristics of anti-leakage that have glass fibre reinforced plastics, long service life.
The beneficial effects of the utility model are: composite pipe of the present utility model has that rigidity height, intensity are good, corrosion resistance and good, hydraulic performance is good, cost is low characteristics.
