Method and facility for adhesion of transverse joints of lining hoses for pipeline in-situ repair

Abstract

The invention provides a method and facility for adhesion of transverse joints of lining hose base materials for pipeline in-situ repair. The method comprises the following steps that an inner sealing strip penetrates through a heating box and is arranged on a plane, the two hose base materials are connected in a butt joint mode and placed on the upper surface of the heating box, and seams are located over the inner sealing strip; a guide rail is pressed on the two sides of the seams of the two hose base materials, a transverse joint thermal compounding facility is arranged in the guide rail and attached to the inner side of the guide rail to limit the position through rolling wheels on the two sides; an outer sealing strip is fixed to a support, and one end of the outer sealing strip is placed between the seams and a pressure roller; in the working process, the hot air temperature rises to the set temperature, then welding guns are pushed downwards, an inner sealing strip welding gun head is inserted into the heating box and fixed, and a traction device is started at the same time; in the advancing process of the device, surface film layers of the inner sealing strip and the outer sealing strip can be partially melted through the hot air sent out by the inner welding gun head and an outer welding gun head, then the inner sealing strip, the outer sealing strip and the seams are compacted through the pressure roller, and therefore the inner sealing strip and the outer sealing strip can be tightly bonded with the inner seam and the outer seam of the base materials. The method and facility can effectively ensure that the transverse joints of the hose base materials for pipeline in-situ repair are firmly bonded, solve the problem of the insufficient length of the hoses, and meet the long-distance construction requirement of pipeline non-excavation repair engineering.

Description

technical field [0001] The invention relates to the field of liner pipe materials for non-excavation repair technology, in particular to a bonding method for bonding horizontal joints of liner hoses for in-situ repair of pipelines, and also provides a horizontal joint for in-situ repair of liner hoses for pipelines. Equipment for joint bonding. Background technique [0002] With the rapid development of my country's social economy and the acceleration of urbanization, the number of underground pipelines in cities is increasing, and the scale of the pipeline network is expanding. Therefore, pipelines need to be retrofitted and updated in stages and batches. For example, using traditional excavation technology to repair old pipelines consumes a lot of resources and affects traffic, urban environment and residents' lives. At this time, trenchless pipeline repair is particularly important. [0003] In recent years, the non-excavation repair technology of urban underground pip...

Problems solved by technology

As an important link in the production of hoses, the transverse joint can effectively make up for the problem of insufficient length of the hose. However, if the strength of the transverse joint is insufficient, it is easy to cause the hose to break when it is turned over and repaired, resulting in the failure of the construction.
