Description

The oversleeve electric smelting connecting device of winding structure pipe and method of attachment

Technical field

The present invention relates to the connected mode of a kind of winding structure pipe, specifically the oversleeve electric smelting connecting device of a kind of winding structure pipe and method of attachment.

Background technology

In the work progress laying plastic drainage pipeline, the tubing used is usually employing high density polyethylene (HDPE) winding structure pipe, this tubing is typically all production with fixed lengths, and, the two ends of every pipe joint material are disposed as socket joint link, rim of the mouth or female mouth that socket joint coordinates it is provided with in socket joint link, socket joint link generally all presets electric fuse, with after pipeline docks, electric fusion welding operation is carried out at joint, thus ensureing the sealing of pipeline joint, it is achieved zero seepage of whole piece plastic lined piping.

But, in Specific construction, when two work surface pipeline docking, because two work surfaces lay simultaneously, when the region that pipe laying to two work surface connects, all tubing and inspection shaft are all fixing, and the bell and spigot causing final section winding structure pipe cannot the phenomenon of abutting joint.Meanwhile, when a pipelining, because tubing and inspection shaft are all fixing, also there will be this phenomenon.In this case, if individually making a joint short tube, because pipeline two ends are often fixed, the seal operation of electric fusion welding cannot be realized at the seam of docking, so, the on-the-spot mode taked is usually homogeneous tube sawed-off by residue tubing laying size, then adopts the measure of cement periphery encapsulating to carry out encapsulation process at the joint connected with saw kerf.After using a period of time due to drainage pipeline, along with the generation of uneven settlement of foundation, will result in the pipe leakage of cement encapsulating place, whole pipeline is paralysed.

Owing to whole pipeline system has multiple work surface, the position of inspection shaft therein is all fixing, so being substantially required for connection and the cement encapsulating of cutting homogeneous tube to carry out final section pipeline between adjacent work surface, therefore, pipeline leaks, the situation of pipeline paralysis is almost all occurring and repeat in city now every day, both caused the inconvenience producing and living, and caused the blocking-up of urban transportation, also increase the workload of repairing;And, cutting remaining winding structure pipe in pipeline laying construction in a large number also just becomes waste product, also result in very big economic loss to unit in charge of construction.

Summary of the invention

It is an object of the invention to provide the oversleeve electric smelting connecting device of a kind of winding structure pipe and method of attachment, to solve the problem that seal for pipe joints that tradition saw pipe docking exists is tight and pipeline easily bursts apart.
