Problems solved by technology

Although this patented technology can realize partial repair of pipelines, it is relatively complicated because the diameter of the stainless steel lining pipe needs to be reduced and expanded, and the connection between the pipeline and the stainless steel lining pipe is difficult to solve the problem of PE. 、The creep problem of PP pipe leads to loose connection and other problems, which affects the effect of long-term use

Embodiment Construction

[0042] The present invention will be further described below in conjunction with the accompanying drawings.

[0043] The structural sectional view of this embodiment is as attached figure 1 As shown, it is composed of a broken pipe 1, a replacement pipe 2, a steel hoop 3, a rubber sleeve 4, a stainless steel strap 5, and a half plate 6.

[0044] The pipeline repair method is as follows:

[0045] The part to be repaired of the ruptured pipeline 1 is cut into two sections;

[0046] Put the steel hoop 3 into the ports of the ruptured pipe 1 and the replacement pipe 2 respectively;

[0047] Align the ports of the ruptured pipe 1 and the replacement pipe 2, and put a rubber sleeve 4 on the joint of the two pipes;

[0048] Lock both ends of the rubber sleeve 4 with a stainless steel pull belt 5 to form a sealed cavity;

[0049] On the outer surface of the rubber sleeve 4, two upper and lower half boards 6 are put on, and the joints of the half boards 6 are locked with screws.

Abstract

A device for the emergency repairing of damaged pipeline is composed of steel-plastic lniing sleeve put ni the ends of the damaged pipe and new pipe to make its external surface matched with their inner surfaces, the elastic ring sleeving on the contact position of said both pipes, and protecting unit sleeving on the external surface of said elastic ring.

Description

technical field [0001] The invention belongs to pipeline repair technology, in particular to a pipeline repair device and a pipeline repair method. technical background [0002] The pipes used for drainage and cable protection will age and partly be damaged after being used for a long time. The current repair methods include electric fusion saddle repair, electric fusion sleeve connection, flange quick connection technology, etc. These technologies are all made of PE material. Good weldability, repaired in the form of homogeneous hot-melt welding. The welding interface required by this method must be clean. However, the accidental rupture or leakage of the water supply pipe usually requires quick repair, and it is difficult to wait until the pipe is completely dry before welding. Special welding equipment is required during construction, so electrical lines must be laid during construction, and a certain installation space is required during install...
