摘要： A method of building underground pipelines by forming a casing in a hole from a forming material which is compacted in the direction from the center of the hole toward its walls. The hole is first filled with the forming material throughout its cross-sectional area and then the material is compacted in the direction towards the walls of the hole. Compaction is effected by a device comprising a rod-shaped body adapted for moving through the hole, the front end of the body being provided with a system of radial ribs.
