SYSTEMS AND METHODS FOR POSITIONING AND RESTORATION WORKING IN PIPELINES repair of main pipelines

摘要

FIELD: transport.SUBSTANCE: set of inventions relates to construction and repair of pipelines and can be used for location of working pipes after fitting of tubular insert inside main pipeline. Prior to fitting the tubular insert, plug with marking magnet is fitted in the opening of working pipe connected with main pipeline. For location and recovery of working pipes after fitting said tubular insert in the main pipe, moving truck with moving magnet, plug with marking magnet and fastener is displaced. Location of working pipes is defined by interaction between marking and moving magnets. Fastener allows fitting of the plug into working pipeline at intersection of working pipe and main pipe. In compliance with other versions, said fastener can mark the plug position in working pipe and remove sad plug therefrom for recovery of hydraulic communication between working pipe and main pipe.EFFECT: accurate location of working pipes.14 cl, 27 dwg
