FIELD: construction. SUBSTANCE: pit is dug out and existing brook 3 is partitioned. Accumulated water is withdrawn to the other side of pipeline 4. Flexible channel 1 is laid into drained brook bottom and, with the aid of wire rope located under pipeline 4, channel 1 is pulled downstream the brook up to the equal distance of channel ends from the center of pipeline 4. Then, heads 2 are brought into ends of flexible channel 1. Flexible water conveyance channel 1 is tightly pressed to bottom of brook 3 on the lower part of half-perimeter of pipeline 4. Panel 5 of nonwoven synthetic material is laid over flexible channel 1 and pipe 4 from its center, and its ends are secured by filled ground. EFFECT: preserved insulation, excluded labor input for water conveyance with pipeline laid in embankment for transportation of medium with positive temperature. 2 dwg
