Abstract
The utility model relates to a mortar pipeline wound by glass reinforced plastics. The mortar pipeline comprises an outer protection layer, a fiber winding layer and a lining layer, wherein a mortar layer is composited and clamped in the fiber winding layer. The outer protection layer, the fiber winding layer, the mortar layer, the fiber winding layer and the lining layer are sequentially arranged from the outside of the pipeline to the inside of the pipeline. The mortar pipeline wound by glass reinforced plastics is light in weight and strong in corrosion resistance, rigidity of the pipeline is enhanced by composting the mortar layer in the fiber winding layer, and manufacture cost is reduced.
Description
Technical field
The utility model relates to a kind of GRP pipe, and specifically a kind of glass fibre reinforced plastics twines sand-inclusion pipeline.
Background technique
The GRP pipe corrosion resistance is strong, good insulating; Be widely used in fields such as chemical industry, electric power, urban water supply and sewerage and natural gas transport, but existing glass steel pipeline structure is generally divided inside liner, construction layer and external protection, these three layers are glass fibre and resin is made; Thereby cause pipeline elasticity modulus low; Therefore often feel in product structure that rigidity is not enough, easy deformation is buried underground down inappositely.Can adopt high modulus fibre or do form such as stiffening rib and remedy if improve pipeline strength, but this kind mode cost is higher.
The model utility content
The purpose of the utility model will provide a kind of glass fibre reinforced plastics to twine sand-inclusion pipeline exactly, to solve the not enough problem of existing GRP pipe-rigidity.
The purpose of the utility model is achieved in that a kind of glass fibre reinforced plastics twines sand-inclusion pipeline, includes external protection, fiber winding layer and the inside liner of glass steel, and compound folder is lined with the burning into sand layer in said fiber winding layer.By pipe outer in be followed successively by external protection, fiber winding layer, burning into sand layer, fiber winding layer, inside liner.
Filler in the said burning into sand layer is the mortar by silica sand and mixed with resin.
Said fiber winding layer is to be made through winding process by glass fibre reinforced plastics.
The utility model is in light weight, corrosion resistance is strong, through folder lining burning into sand layer in fiber winding layer, has both increased the rigidity of pipeline, owing to reduced the thickness and the material consumption of fiber winding layer, has therefore also just reduced the integral manufacturing cost of pipeline simultaneously.
Description of drawings
Fig. 1 is the partial structurtes schematic representation of the utility model.
Among the figure: 1, external protection, 2, the burning into sand layer, 3, inside liner, 4, fiber winding layer.
Embodiment
As shown in Figure 1, the structure of the utility model be by pipe outer in be followed successively by external protection 1, fiber winding layer 4, burning into sand layer 2, fiber winding layer 4, inside liner 3.The pipeline integral body that is arranged so that of fiber winding layer 4 has good bending resistance, high corrosion resistance, low choked flow and low manufacture cost.Fiber winding layer 4 is to be made through winding process by glass fibre reinforced plastics.Filler in the burning into sand layer 2 is the mortar by silica sand and mixed with resin.Fiber winding layer 4 is set respectively inside and outside burning into sand layer 2 can makes the burning into sand layer bring into play self intensity and rigidity to greatest extent, even when stressed, the burning into sand layer produces slight crack, because the existence of inside and outside fiber winding layer 4 can not cause the pipeline global failure yet.External protection is the glass fibre reinforced plastics outer surface layer of pipe, has good corrosion resistance.Inside liner 3 is to have smooth glass fibre reinforced plastics inwall, can play anticorrosive effect, makes that also the flow resistance of pipeline is very low, thus the working life of having improved pipeline.Inside liner 3 has insulating property, is adapted to transmission of electricity, telecommunication line compact district and area with more lightning activities etc.
Claims (2)
1. a glass fibre reinforced plastics twines sand-inclusion pipeline; Include external protection (1), fiber winding layer (4) and the inside liner (3) of glass steel; It is characterized in that; Be compounded with burning into sand layer (2) in the said fiber winding layer (4), pipeline is followed successively by external protection (1), fiber winding layer (4), burning into sand layer (2), fiber winding layer (4), inside liner (3) from outside to inside.
2. glass fibre reinforced plastics according to claim 1 twines sand-inclusion pipeline, it is characterized in that said fiber winding layer (4) is to be made through winding process by glass fibre reinforced plastics.
