Description

The volute link

Technical field

The utility model relates to a kind of water supply and sewerage pipeline, particularly a kind of volute link.

Background technique

Plastic spiral coil and plastic hollow wall spiral winding pipe are 1920's, bury ground conveyance conduit as main industrial or agricultural and municipal administration with the heavy caliber that buries purposes such as ground draining, blowdown, irrigation from the alternative reinforced concrete pipe of external introduction, after this, the steel band of China's independent intellectual property right strengthens the PE helical bellows and also comes out one after another, because steel band strengthens the ring stiffness height of PE helical bellows, anti-pressure ability is good, and is corrosion-resistant, since coming out, be used widely, good development prospect is arranged.

Steel band strengthens the connecting means of PE helical bellows, normally after an end of two sections pipelines that need to connect and the other end close up, wrap up welding with hot melt band or Electric thermal smelting belt in the jointing appearance of two segment pipes earlier, use plastic welding gun heating of plastic welding rod again, interface slit in the welded pipe line, the corresponding site of last soldering opening again outside and hot melt band or Electric thermal smelting belt welding is to play the interconnect function of sealing (closing water) and two pipes.Because the fusion techniques of these two kinds of methods, the construction team of common engineering contractor is difficult for grasping, there is not this equipment yet, to send the professional workforce to be with special device to weld and welding by the producer that produces pipeline to the job site, not only time-consuming but also require great effort, producer's after cost of producing pipeline is increased, in addition, meet under ponding or the rainy situation when the job site, must ponding be drained with suction engine, or with the water drainage, otherwise can't construct, because the charged submersible of workmen exists dangerous greatly, potential safety hazard is difficult to get rid of, and operation is in the open air met and is difficult to construction under the power free situation especially, when caliber during less than people's height, more because of the workmen can't enter in the pipeline construction welding, the result is a welded tube outward not in the welded tube, rushes through.
