Abstract
The utility model provides a glass reinforced plastic sand pipe. The glass reinforced plastic sand pipe comprises a lining layer, wherein a sand layer wraps the lining layer; a twining layer wraps the sand layer; flue wraps the outer side of the twining layer to form a middle layer; an outer protection layer is arranged outside the middle layer; reinforcement ribs are arranged between the middle layer and the outer protection layer. The glass reinforced plastic sand pipe has the advantages that a lining is adopted for enhancement, the middle is wear-resisting and anti-crack, the rigidity of a pipe is enhanced by the reinforcement ribs, and the outer surface is wear-resisting. Combining the inside with the outside, the pipe which is provided by the scheme has the characteristics of excellent corrosion prevention, wear resistance and crack prevention.
Description
Technical field
The utility model relates to pipeline field, refers in particular to a kind of glass reinforced plastic sand pipe.
Background technique
The pipeline using in current water supply and sewage work mainly contains cement pipe, cast iron tube, steel pipe, steel-plastic composite pipe and plastic pipe etc.; All there is shortcoming separately in aforementioned tubes: plastic pipe includes pvc pipe, PE pipe, PP pipe etc., and its cost of raw material is low, manufacture is simply widely used, but when manufacturing large-diameter pipe, higher to required precision, and rigidity is inadequate; Cement pipe intensity is low, density greatly, not corrosion-resistant and Heavy Weight, transportation difficulty; Steel pipe, cast iron tube be corrosion resistant not, and cost is high, Heavy Weight, is also difficult for transportation; Steel is moulded pipe and is generally used for minor diameter draining, and cost of production is high.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and the glass reinforced plastic sand pipe of a kind of simple in structure, low cost of manufacture, long service life is provided.
For achieving the above object; technological scheme provided by the utility model is: a kind of glass reinforced plastic sand pipe; it includes inside liner; inside liner is coated with burning into sand layer; burning into sand layer is coated with winding layer; winding layer outside is covered glue and is formed mesosphere, and outside, mesosphere is provided with external protection, between mesosphere and external protection, is provided with stiffening rib.
Described winding layer adopts glass fibre and resin to make Wrapping formed.
Described stiffening rib distributes or is spirally wound on outside, mesosphere along pipe length direction.
After described stiffening rib inlays, by screen cloth, be wound around and cover again rubber-surfaced roll swaging and become external protection.
The utility model has the advantage of and adopt liner enhancing, middle wear-resistant and crack-resistant, stiffening rib strengthens the rigidity of tubing, and appearance is wear-resisting; Adopt and to make after the combination of inner and outside tubing of this programme there is the characteristics such as good anticorrosion, wear-resisting, cracking resistance.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with institute's drawings attached, the utility model is described in further detail, preferred embodiment of the present utility model is: referring to accompanying drawing 1, glass reinforced plastic sand pipe described in the present embodiment includes inside liner 1, inside liner 1 is coated with burning into sand layer 2, and it is that main material is made moulding that burning into sand layer 2 adopts resin and silica sand; Burning into sand layer 2 is coated with winding layer 3, and winding layer 3 adopts glass fibre and resin to make Wrapping formed; Winding layer 3 outsides are covered glue and are formed mesosphere 4, and 4 outsides, mesosphere are provided with external protection 5, between mesosphere 4 and external protection 5, are provided with stiffening rib 6, and stiffening rib 6 distributes or is spirally wound on 4 outsides, mesosphere along pipe length direction.After the stiffening rib 6 of the present embodiment inlays, by screen cloth 7 windings, cover again rubber-surfaced roll swaging and become external protection 5.This programme adopts liner enhancing, middle wear-resistant and crack-resistant, and stiffening rib strengthens the rigidity of tubing, and appearance is wear-resisting; Adopt and to make after the combination of inner and outside tubing of this programme there is the characteristics such as good anticorrosion, wear-resisting, cracking resistance.
The embodiment of the above is only the preferred embodiment of the utility model, not with this, limits practical range of the present utility model, therefore the variation that all shapes according to the utility model, principle are done all should be encompassed in protection domain of the present utility model.
