Description
Technical field
The utility model relates to a kind of plastic pipe, is specifically related to the non-excavation pipeline of the scratch resistant plastics of a kind of appearance.
Background technique
Pipeline construction is divided into excavation and two kinds of non-excavations, non-excavation refers to by means such as guiding, directional drillings in the situation that earth's surface small part excavates and (refers generally to entrance and exit small size excavation), lay, change and repair the construction technique of various underground utility, therefore surface drying is disturbed littlely over the ground, has higher social economic effect.Therefore, at present increasing pipeline construction comprises that plastic pipe construction all takes trenchless technology.
Plastic tube is compared with pipelines such as traditional cast iron tube, Coating Steel Pipe, cement pipe, there is energy-saving material-saving, environmental protection, high-strength light, corrosion-resistant, inner wall smooth non-scaling, construction and the advantage such as maintenance is easy, long service life, be widely used in building industry, municipal administration, industry and the agriculture fields such as building water supply and drainage, town and country plumbing, gas, electric power and cable sheath, industrial fluids conveying, agricultural irrigation.Plastic pipe is an important branch in the numerous constituent elements of chemical building material, from using the difference classification of chemical materials, plastic pipe can be divided into polyethylene (PE) pipe, PVC＝polyvinyl chloride (PVC) pipe, polypropylene (PP) pipe, ABS pipe, polybutylene (PB) pipe etc.
PE(polyethylene) material, due to features such as its intensity are high, corrosion-resistant, nontoxic, is widely used in water pipe and manufactures field.Because it can not get rusty, so, be the desirable tubing that substitutes common iron water pipe.
But the PE water pipe of conventional use is when for non-excavation, because PE surface is softer in the market, so easily scratch tube surfaces in poling process, destroy the stressed of tubing, at long-term high pressure and kickback pressure, make easily to cause the explosion of PE tubing, greatly reduce the working life of pipeline like this.
Therefore, in order to meet the demand in market, for socioeconomic development, be necessary, develop the non-excavation pipeline of the scratch resistant plastics of a kind of appearance.
Summary of the invention
Goal of the invention: the purpose of this utility model is in order to solve the deficiencies in the prior art, provides the scratch resistant plastics of a kind of appearance non-excavation pipeline.
Technological scheme: in order to realize above object, the utility model is by the following technical solutions.
