Description

Unreinforced part and main pipe and branch pipe joint maintenance system,

The present invention relates to a non-drilled portion, a main pipe and a branch pipe joint pipe repairing system, and more particularly, to a pipe pipe repairing system using a control device and a ultraviolet packer to prevent cracks and partial breakage And a maintenance system for maintenance of the main pipe and the branch pipe joint.

After inserting the reinforcing tube impregnated with the thermosetting resin into the tube (nonwoven fabric or glass fiber) coated on one side with the inside of the old pipe without excavation, the hot water or steam is supplied to the inside of the reinforcing tube And the reinforcing tube can coat the inside of the pipe by inflating it, thereby repairing the non-excavation.

In order to repair the part where the existing pipeline breaks and the water penetrates into the pipeline, it is necessary to cut the glass fiber so as to have a constant interval (catcher width of about 400 mm) The inner diameter of the pipeline was coated.

After repairing the inner diameter of the pipeline, a hole is drilled in the portion to which the branch pipe is connected so as to match the branch pipe, so that normal supply to the branch pipe is performed. However, the connection portion of the branch pipe and the pipe, It was very difficult to repair the part to prevent leakage if it was damaged.

In addition, even if normal supply to the branch pipe is made by drilling a hole in the part connected to the branch pipe after repairing the inner diameter of the pipe, if there is a leak in the connection part of the branch pipe and the branch pipe, And there was a drawback that the leakage phenomenon occurred the most at the connecting portion between the branch pipe and the pipeline.

In order to prevent leakage of water from the connection between the branch pipe and the pipe, a process of cutting a part of the pipe and connecting a new pipe, or repairing the inner diameter of the pipe with a reinforcing tube and then drilling the hole It is very difficult to puncture a hole that can accurately connect the branch pipe and the pipe line, so that there is a drawback that the leak water can not be properly blocked even after the repair.

Patent Registration No. 0791511 (registered on December 27, 2007) for preventing such drawbacks is a method of applying adhesive curable resin to a branch pipe felt member which is joined to a pipeline and a branch pipe, The repairing member is fixed by fixing the branch maintenance member integrally in the form of "⊥" to the pipeline and the branch pipe, but the process of reversing the pipe to cover the branch pipe after moving to the repair position with the tube has a complicated and difficult drawback.
