Description
Technical field
The present invention relates to buried pollution discharge tubing, particularly relate to a kind of modified polythene tube for buried pollution discharge.
Background technology
The modified poly ethylene tubing system is started late, but development is very fast, especially in the Europe of paying attention to environment protection most.In recent years the raw-material performance of polyethylene (PE) tubing pipe improves constantly, the mixed ingredients of PE100 grade generally adopts for various countries, has also developed ' the eutectic hang down ' the high workability PE100 ' of property PE100 ' (low flow) and injection moulding large sized fittings of suitable production thick-wall and large-diameter pipe.The petrochemical industry of China is active development pipeline PP Pipe Compound in recent years, estimates that the production domesticization of PE100 has major progress soon.
Developing large diameter PE tubing penstock, almost is unique plastics tubing at the above scope PE pipe of diameter 1000mm.The maximum diameter of extruding PE tubing solid wall pipe abroad reaches 2000mm, and China has not only produced and used the larger-diameter PE penstock of 630-1600mm, and can make the extruding production line and the supporting welding set of major diameter PE solid wall pipe.PE pipe and traditional ductile iron pipe and steel pipe ratio, health, anticorrosive, laying convenient and swift is its advantage.For example always also in the middle grid of laying newly, successfully adopted diameter to reach the modified polythene tube solid wall pipe of 1000mm in a large number in 06 year using Beijing area more careful and conservative on the plastic conduit.
Non-excavation laying be used for new pipeline laying and old pipeline rehabilitation because economic and social benefit all get well use in the world more and more, in China also in progressively popularization.PE tubing pipeline is pliable and tough, and the characteristic of weldable becomes the first-selection of non-excavation-use pipe naturally.Develop the multiple PE tubing tubing that particular requirement is arranged in the world for adapting to non-excavation laying, part also starts to walk in China, for example: more pliable and toughlyer be fit to carry out undergauge and zigzag PE tubing; The PE tubing that the protection surface layer is arranged, the i.e. anti-material of drawing damage of wiping of the compound one deck in outside.' no sand is laid ' PE pipeline is external a kind of in recent years new laying method.Be exactly that the PE pipe need not be embedded in ' in the casting bed ' (protecting with sand around the tubing) according to traditional laying standard, can be laid immediately in the original soil (may contain sharp stone etc.).The pipe trench of opening like this can be very narrow, do not need external embedding material, perhaps adopts ' plough is gone into laying method ' to cover while ditching and bury.Obviously, this laying method can reduce the laying expense and improve laying speed, but requires tubing to have the performance that damage and the load of anti-point are drawn in anti-wiping.
And buried drain pipe is divided into row rainwater pipe and sewage pipe two classes according to purposes, and technical requirements is the distinguishing requirement difference of sealing property (particularly for).And the domestic row of being regardless of at present rainwater, sewer adopt identical product standard and technical regulation (just to whether require to do closed-water test have any different).
In recent years because the quick-fried of the PE prices of raw and semifnished materials risen, the promotion and application of PE tubing system are under great stress.
