FIELD: construction.
SUBSTANCE: trench-burying device comprises a frame, a displacement mechanism, two dump scrapers and an accessory for displacement of dump scrapers. Dump scrapers are arranged symmetrically to the longitudinal axis of the frame symmetry, are hingedly connected to the frame and are installed as capable of rotation in the horizontal plane. The trench-burying device comprises an accessory for monitoring a displacement course and a guide block. The guide block is arranged with a connection element and with a working surface for interaction with the external surface of the installed pipeline. One end of the connection element is kinematically connected with the guide block. The connection element with the other end is connected to the frame by means of the hinged joint, which is arranged on the longitudinal axis of the frame symmetry. The accessory to monitor the displacement course is kinematically connected with the guide block.
EFFECT: higher efficiency under conditions of poor visibility due to reduced number of additional movements when changing spatial position of a trench.
