TRAINING DEVICE FOR INSTALLATION WHOLE long-length tubes for trenchless REPLACEMENT OF ENGINEERING NETWORKS

摘要

The invention relates to construction technology and concerns methods and devices for trenchless pipeline replacement. The technical result of the proposed utility model - expanding functionality by replacing the old pipeline lengthy pipe without cutting it. The starting well (not shown) lowers the base 8, which is mounted directly in front of the flipper pipe (not shown). The base 8 inserted into the vertical rolls 1 and 2 in an extended state. After mounting the device in the start pit in its tightened rope of a suction well vertically downwards a new tube 6 (the sump and a cable not shown in the drawings). When passing through the horizontal drum occurs flattening and bend pipe 6. After passing through the rolls 1 and 2 destructive tip (not shown) the rolls 1 and 2 bring together by means of the hydraulic cylinder and the arms 4 and 5 in parallel position, restoring original germetriyu tube 6. subsequently produce pipeline relaying known methods.
