FIELD: construction.SUBSTANCE: group of inventions relates to construction of pipelines and may be used for simultaneous installation of several items inside underground pipelines, for instance, communication cables, traction ropes, pipelines. A system (10) for simultaneous introduction of a cable (11) and another item (21) into a pipe (12) includes a pushing mechanism (13) and an air-blowing machine (15), which insert the cable (11) into the pipe (12). The pipe (12) is separated near the pushing mechanism (13) so that the item (21) could be connected to the cable (11) with the help of a connecting accessory (25), attached to a head (23) on the front end of the cable (11). In another version to the front end of the cable (11) there may be a gear (35) attached, and the item (21) may be attached in the place of connection of the cable (11) and the gear (35). A block (18) connects separated ends (16, 17) of the pipe (12), and the cable (11) and another item (21) may be moved together along the pipe (12) with the help of the pushing mechanism (13) and the air blowing machine (15), which supplies air to the gear (35) for assistance to this movement.EFFECT: increased efficiency of simultaneous insertion of several cables or other items into a long pipe.8 cl, 3 dwg |
