Abstract
The utility model discloses a concrete and glass-fibre reinforced plastic (GRP) composite pipeline, aiming at providing a concrete and glass-fibre reinforced plastic (GRP) composite pipeline with the advantages of corrosion-resistant, high strength, small flow resistance, low manufacturing and using cost, and convenient paving. The concrete and glass-fibre reinforced plastic (GRP) composite pipeline comprises a circular tubular concrete layer; the utility model is characterized in that the circumference of the inner wall of the concrete layer is provided with a glass-fibre reinforced plastic (GRP) layer. A quartz sand layer is arranged between the concrete layer and the glass-fibre reinforced plastic (GRP) layer. The glass-fibre reinforced plastic (GRP) layer is formed by winding glass fibre or glass fibre fabric in circular shape; and the concrete layer consists of cement concrete or reinforced cement concrete. In the utility model, the inner wall of the concrete layer is lined with the glass-fibre reinforced plastic (GRP) layer, so that the concrete and glass-fibre reinforced plastic (GRP) composite pipeline not only has the strength of a concrete pipeline, but also has the low flow resistance and corrosion-resistant performance of a GRP pipeline. In the utility model, the concrete layer and the GPR layer have high adhesive attraction; the utility model can be manufactured with low cost, has long service life, does not have pollutant leakage, and has good environment protective performance.
Description
Technical field
The utility model relates to the conveyance conduit that is used for liquid, the particularly a kind of concrete of the supply and drain water system that is used for sewage in factory and city and the multiple tube of glass fibre reinforced plastics.
Background technique
In the sewage supply and drain water system that factory and city are used, generally be to use concrete duct, for also using steel reinforcing in the large-scale concrete duct, cost is lower.But owing in the concrete member slight void is arranged, so its impermeabilisation ability, reinforcing bar sewage medium-term and long-term soak produce rot, intensity and working life that expansion, explosion destroy pipeline, there is the liquid of contaminativity also can be penetrated into pipeline outer wall for conveying, pollute, and this inner-walls of duct is coarse, adheres to easily, accumulating over a long period makes the pipeline constriction in flow area, reduces negotiability.Though can solve with the pipeline of glass fibre reinforced plastics, if the too thin bearing capacity that can influence pipeline of fiber reinforced plastic pipe wall, especially bigbore pipeline; If increase pipeline wall thickness manufacture cost is improved greatly, seem not too economical.
The model utility content
The utility model provide a kind of have corrosion-resistant, intensity is high, flow resistance is little, manufacturing cost and use cost is low, lay concrete glass fiber reinforced plastic multiple tube easily.
In order to reach above-mentioned requirements, the utility model is achieved through the following technical solutions: it comprises round tubular concrete layer, it is characterized in that the inwall circumference of concrete layer is provided with frp layer.
Be provided with quartz sand layer between described frp layer and the concrete layer.Described frp layer is formed by glass fibre or glasscloth annular wound and solidified.Described concrete layer is made up of cement concrete or reinforced cement concrete.
The concrete glass fiber reinforced plastic composite pipe of making according to such scheme is lined with frp layer at the inwall of concrete layer, makes the intensity of whole concrete glass fiber reinforced plastic composite pipe existing concrete conduit, and the low flow resistance and the corrosion resistance of fiber reinforced plastic pipe arranged again.Concrete layer and frp layer strong adhesion, low cost of manufacture, long service life can not produce the phenomenon that pollutant oozes out, good environmental protection.
Description of drawings
Figure is the sectional drawing of concrete glass fiber reinforced plastic composite pipe.
Wherein: 1, concrete layer; 2, frp layer; 3, quartz sand layer.
Embodiment
The utility model will be further described below in conjunction with the drawings and specific embodiments.
As seen from the figure, it comprises round tubular concrete layer 1 the concrete glass fiber reinforced plastic composite pipe, and the inwall circumference of concrete layer 1 is provided with frp layer 2.Between frp layer and concrete layer, be provided with quartz sand layer 3.Described frp layer 2 usefulness glass fibres or glasscloth annular wound and solidified form.Described concrete layer 1 is formed by cement concrete or reinforced cement concrete cast.
The process of producing can be the prefabricated frp layer 2 of elder generation, at frp layer 2 setting up period, at the outer surface of frp layer 2, sprinkle one deck silica sand, make silica sand be bonded in frp layer 2 outer surfaces, make its rough surface, at quartz sand layer 3 outer surface casting cement concrete or reinforced cement concretes, form concrete layer 1 again, can improve the combination force between concrete layer 1 and the frp layer 2 like this, can not separate, technology is simple.Also can at direct casting cement concrete of the outer surface of frp layer 2 or reinforced cement concrete, form concrete layer 1 in the such scheme without silica sand.Or after adopting concrete layer 1 and frp layer 2 to make respectively, frp layer 2 is secured on the inwall of concrete layer 1.
Claims (4)
1, concrete glass fiber reinforced plastic multiple tube, it comprises round tubular concrete layer, it is characterized in that the inwall circumference of concrete layer is provided with frp layer.
2, concrete glass fiber reinforced plastic multiple tube according to claim 1 is characterized in that being provided with quartz sand layer between described frp layer and the concrete layer.
3, concrete glass fiber reinforced plastic multiple tube according to claim 1 is characterized in that described frp layer is formed by glass fibre or the winding of glasscloth annular.
