Abstract
The utility model relates to a glass fiber reinforced plastic sand inclusion pipe, which comprises a structure layer and an inner lining layer, wherein the structure layer comprises an inner winding layer and an outer winding layer, a sand inclusion layer is arranged between the inner and the outer winding layers, and the outer surface of the outer winding layer is provided with an outer protective layer. The inner lining layer is compounded on the inner surface of the inner winding layer, the sand inclusion layer comprises at least two layers, and two adjacent sand inclusion layers are pasted together. A plurality of sand inclusion layers are arranged between the inner and the outer winding layers in the glass fiber reinforced plastic sand inclusion pipe for increasing the strength of pipelines. The inner lining layer and the outer protective layer are made of glass fibre hair and corrosion resistant high intensity resin, the surface of the pipeline is formed into a dense, smooth and hard casing, and the leakage prevention performance, durability and corrosion resistance of the pipeline can be increased effectively. The utility model can be used for water supply and sewerage pipes, gas pipes, ash discharge pipes, silt discharge pipes, slag conveying pipes, ordinary industrial pipelines, etc.
Description
Technical field
The utility model relates to pipeline, particularly glass reinforced plastic sand pipe.
Background technique
The pipeline that uses in the current water supply and sewage work mainly contains cement pipe, cast iron tube, steel pipe, aluminium-plastic composite pipe and high density polyethylene pipe etc.Concrete duct intensity is low, density is big, and is not corrosion-resistant, and the tube wall breed bacteria has pollution to water quality, stops using in developed country at present.Steel pipe, cast iron tube are not corrosion-resistant, cost height, Heavy Weight, difficult transportation.Aluminium-plastic composite pipe just is used for the cold water pipe of minor diameter, typically has a diameter from 50-60mm, and cost of production is very high.The intensity of high density polyethylene pipe is low, not high pressure resistant, big, flexible, the easy booster of distortion, and the cost height, and also every length is had only 2-3m, inconvenience is installed.
Glass reinforced plastic sand pipe is on the basis of the up-to-date pipe production technical development in conjunction with the world today, the low-cost composite material burning into sand pipe of optimal design.The glass reinforced plastic sand pipe of producing both at home and abroad is made up of construction layer and inside liner mostly at present, and its construction layer generally is made up of fiber fw frp layer and resin mortar layer.The glass reinforced plastic sand pipe intensity of this structure is low, leak resistance is poor.
Summary of the invention
The purpose of this utility model provides a kind of intensity height, glass reinforced plastic sand pipe that leak resistance is good.
The utility model glass reinforced plastic sand pipe comprises construction layer and inside liner; winding layer and outer wrap in described construction layer comprises; the burning into sand layer is set between the inside and outside winding layer; the outer surface of outer wrap is provided with external protection; the internal surface of winding layer in described inside liner is compound in; described burning into sand layer comprises that two two-layer at least, adjacent stratified sand layers bond together.
This glass reinforced plastic sand pipe is provided with several layers burning into sand layer between inside and outside winding layer, improved the intensity of pipeline greatly.It adopts glass fibre hair and corrosion-proof and high-strength resin to make inside liner and external protection, forms closely knit, smooth, the hard shell of one deck at pipe surface, can effectively improve anti-leakage, durability and the corrosion resistance of pipeline.Can be widely used in supplying drainage, gas pipe, ash releasing tube, desilting tube, slag delivery pipe and general industry pipeline etc.
The utility model can also be provided with the looped network layer between interior winding layer and inside liner, this looped network layer adopts the preposition tension system technology of glass fibre, make fiber tension even, and the resin wellability is good, thereby makes the hoop of glass reinforced plastic sand pipe and axial intensity be further enhanced.
Description of drawings
Fig. 1 is the structural representation of the utility model tube wall.
Embodiment
Be described further below in conjunction with accompanying drawing.
As shown in Figure 1; this glass reinforced plastic sand pipe comprises construction layer and inside liner 6; winding layer 4 and outer wrap 2 in described construction layer comprises; burning into sand layer 3 is set between the inside and outside winding layer; the outer surface of outer wrap 2 is provided with external protection 1; the internal surface of winding layer 2 in described inside liner 6 is compound in, described burning into sand layer 3 comprises four layers, two adjacent stratified sand layers adopt adjacent benzene type alkyd resin to bond together.Also can adopt other binder bonding.
Between interior winding layer 4 and the inside liner 6 looped network layer 5 is set.It is that main material is made that looped network layer 5 adopts glass fibre and resin.By adopting the preposition tension system technology of glass fibre, make fiber tension even, and the resin wellability is good, thereby makes the hoop of glass reinforced plastic sand pipe and axial intensity be further enhanced.
It is that main material is made that burning into sand layer 3 adopts resin and silica sand.
Inside liner 6, external protection 1 are made up of glass fibre hair and anti-corrosion, high-strength resin, make the inside and outside surface of pipeline form closely knit, smooth, the hard shell of one deck, to increase anti-leakage, durability and the corrosion resistance of pipeline.Interior winding layer 4 and outer wrap 2 are by intersecting the glass fibre zero twisted yarn composition that twines.Adopt compound sticking to connect between adjacent two-layer of inside liner 6, looped network layer 5, interior winding layer 4, burning into sand layer 3 and outer wrap 2.
This glass reinforced plastic sand pipe has that cost is low, in light weight, corrosion-resistant, nontoxic pollution-free, tube wall is smooth, intensity is high, good springiness, do not break, advantage such as long service life.Can be widely used in municipal supplying drainage, building water supply and drainage pipe, power plant's supplying drainage, gas pipe, ash releasing tube, desilting tube, slag delivery pipe and general industry pipeline etc.It is particularly useful for the application of heavy caliber water delivery, diversion and sewage treatment pipeline, the tube wall diameter can be designed to 150-4000mm, and the effective length of every pipeline can reach 12m, has reduced transportation and mounting cost, reduce the connecting head of pipeline, improved the Security of pipeline.This pipeline can be imbedded the underground 10m that reaches deeply, the interior pressure that can bear maximum 2.5Mpa.
Because inner-walls of duct is smooth, lower by 40% than the power consumption of cement pipe under the situation of same carrying capacity, electric power resource that can saves valuable has remarkable economic efficiency and social benefit.
