Abstract

The utility model discloses a novel glass fibre-reinforced plastic sand-filled pipe, sequentially comprising an outer protecting layer, an outer structural layer, a sand-filled layer, an inner structural layer, and a lining layer from outside to inside, wherein the inner layer of the outer protecting layer is provided with the outer structural layer; the inner layer of the outer structural layer is wound with the sand-filled layer; the inner layer of the sand-filled layer is provided with the inner structural layer; the inner layer of the inner structural layer is wound with the lining layer; and the sand-filled layer is formed by uniformly mixing quartz sand and resin with different meshes, and filled by a wet process. The novel glass fibre-reinforced plastic sand-filled pipe disclosed by the utility model is reasonable in structural design; and because of the wet-process sand-filling, the quartz sand and the resin can be uniformly mixed, and the gap between the quartz sand and the resin is small, thus reducing the content of the resin in the sand-filled layer, decreasing cost, and improving the compactness of the sand-filled layer, so that the quality of the product is improved.

Description

A kind of novel glass fiber reinforced plastic burning into sand pipe

Technical field

The utility model relates to the pipe technology field, relates in particular to a kind of novel glass fiber reinforced plastic burning into sand pipe, is mainly used in heavy caliber draining, water supply, blow-off line.

Background technique

The employed silica sand level of glass fiber reinforced plastic burning into sand pipe industry can not satisfy each item technical order of pipeline itself at present, and each item technical order of pipeline itself is had adverse influence.Because glass fiber reinforced plastic burning into sand pipe is widely used at home, the technology of glass-fiber reinforced thermo-setting resin burning into sand pipe is updated, and improves the technical performances such as each item index of glass-fiber reinforced thermo-setting resin burning into sand pipe more; But the RPM cost is high; In use for some time, the liner of finding RPM is through long-term a large amount of current scour, and obvious layering appears in tube wall; Phenomenons such as tensile fiber destroys, comes off have been brought great hidden to safety.

The model utility content

For overcoming deficiency of the prior art, the purpose of the utility model is to provide a kind of liner to strengthen intensive, anti-corrosive properties, novel glass fiber reinforced plastic burning into sand pipe that wear resistance is good.

To achieve these goals; The technological scheme that the utility model adopted is: a kind of novel glass fiber reinforced plastic burning into sand pipe; Comprise external protection, external structure layer, burning into sand layer, inner structure layer, inside liner from outside to inside successively, it is characterized in that described external protection internal layer is provided with the external structure layer, the internal layer of external structure layer twines and is provided with the burning into sand layer; The internal layer of burning into sand layer is provided with the inner structure layer, and the internal layer of inner structure layer twines and is provided with inside liner.

Described burning into sand layer is that silica sand and the resin by different meshes evenly mixes, and adopts the wet method burning into sand.

Described external protection is to soak into unsaturated polyester resin by glass fiber to process.

The beneficial features of the utility model is: reasonable in design, and structure adopts inside liner, has strengthened degree of compaction; Established external protection again, inside and outside intensity has been strengthened greatly, owing to adopt the wet method burning into sand; Silica sand can evenly mix with resin, and the gap between silica sand and the silica sand is little, thereby has reduced burning into sand layer resin content; Reduced the degree of compaction that cost has improved the burning into sand layer simultaneously, the quality of product is improved.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is described further;

Fig. 1 is the structural representation of the utility model;

Among the figure, 1, inside liner, 2, the inner structure layer, 3, the burning into sand layer, 4, the external structure layer, 5, external protection.

Embodiment

As shown in the figure, a kind of novel glass fiber reinforced plastic burning into sand pipe comprises inside liner 1; Inner structure layer 2, burning into sand layer 3, external structure layer 4; External protection 5, the skin of inside liner 1 is provided with inner structure layer 2, and the skin of inner structure layer 2 is provided with burning into sand layer 3; The skin of burning into sand layer 3 is provided with external structure layer 4, and the skin of external structure layer 4 is provided with external protection 5.More than show and described the basic principle and the major character of the utility model; The technician of the industry should understand; The utility model is not restricted to the described embodiments, and the principle of describing in the foregoing description and the specification that the utility model just is described is under the prerequisite that does not break away from the utility model spirit and scope; The utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.
