FIELD: process engineering.SUBSTANCE: invention can be used in repair of oil pipelines laid in marshlands, overwetted or loose sands. In compliance with this process, repair chamber semi-cylinder bottom is fitted on pipeline from above and provided with arched cut-outs at ends and swing-out mechanism including two grippers arranged at bottom ends, each comprising two hinged gripping elements with rollers. Note here that said bottom is mounted with its arched cut-out directed downward. Then bottom swing-out mechanism is locked by pipeline grippers by making said rollers contact with its surface to turn the bottom through 180 degrees. Then, chamber box-like case with arched cut-outs is fitted in pipeline to align the latter with bottom cut-outs for case and bottom to be tightly coupled together. Now, clearances between pipeline and chamber are sealed at both arched cut-outs.EFFECT: ease of erection.3 cl, 4 dwg |
