Abstract
The invention relates to a method for carrying out rush repair on a steel-skeleton polyethylene plastic composite pipe with water and under pressure. The method comprises the following steps: firstly, polishing and sealing the pipe breakage parts of the pipe, and sleeving the inner connection parts of two T-shaped gaskets with two circular sealing gaskets respectively; secondly, installing the inner connection parts of T-shaped gaskets sleeved with the sealing gaskets on the pipe and a short rush-repair pipe respectively, pressing the sealing gaskets between the pipe and the outer connection parts of the T-shaped gaskets through connection between the inner connection parts of the T-shaped gaskets and the pipe, arranging an O-shaped sealing ring between the outer connection parts of the two T-shaped gaskets, and oppositely tensioning the two sections of the pipe by virtue of a tensioning device; and thirdly, installing, and then welding electrofusion sleeves. Accumulated water in the pipeline can be effectively prevented from entering into the electrofusion sleeves from the butt-joint part of the pipeline to influence the welding quality of the electrofusion sleeves and a pipe wall after the method is used.

Plus two times this device length；Using combination pliers is as much as possible, skeleton parallel steel wire ring is removed, by broken end nail after pinch off
Enter in plastics；Slotted using the angle grinder equipped with grinding wheel, cell body should be centered on warp steel wire, gradually to outside both sides
Expand, the inside and outside wall of pipeline also to be ensured has the plastic thickness no less than 2mm simultaneously；Conduit section and cell body are carried out purging, clean
Process, and intercept clean welding rod in right amount, start feeding after the preheating fully of plastic extrusion welding machine, temperature is adjusted according to discharging effect
Control knob, when the solder of extrusion is molten condition and no shinny, carbonization phenomenon, discharging opening is directed at cell body and circumferentially at the uniform velocity send
Material, till cell body is covered by solder completely.
Then use the angle grinder equipped with resin sand video disc molten to electro-fusion sleeve inwall, the melting zone of tubing and repairing short tube
Polished in area, tubing polishing length is electro-fusion sleeve length, and the electro-fusion sleeve after 2 are polished is contained on tubing respectively in advance.
Finally two circular gasket seals are respectively fitted on the interior connecting portion of two T-shaped pads, then two are covered
Interior connecting portion equipped with the T-shaped pad of gasket seal is respectively pivoted in tubing and repairing short tube, by the interior connecting portion of T-shaped pad
It is connected with tubing and repairing short tube, so that gasket seal is pressed between tubing or repairing short tube and T-shaped pad, will be O-shaped close
Seal is arranged between the outer connecting portion of two T-shaped pads, by two sections of tubing and rushes to repair short tube phase using strainer or centralizer
To tension, and ensure that tubing and the repairing short tube center of circle, in same axle, two pieces electro-fusion sleeve are tapped towards strong length pipe direction, makes
Its 1/2 electro-fusion sleeve length of advancing, then weld electro-fusion sleeve.
Further, the outer connecting portion of at least one T-shaped pad arranges groove, described O-ring seal is passed through described recessed
Groove is arranged on described outer connecting portion.
Have the beneficial effects that using produced by technique scheme：
The present invention is simple to operate, effectively achieve to SRPE band water, with pressure rush to repair, save
Emergency repair time, reduces the loss that client brings because of pipeline shutdown.During repairing operation, after to disconnected pipe, padded as stated above
The mouth of pipe is strained by the installation of piece using take-up device, then installs, welds electro-fusion sleeve again.Using can be effective after the method
Stop that the ponding in pipeline enters into inside electro-fusion sleeve from pipeline joint, thus avoiding its impact electro-fusion sleeve and tube wall
Welding quality.
