FIELD: construction engineering; laying underground drainage conduits in water-deposited soils. SUBSTANCE: guide trench is made between inlet and outlet foundation pits; said trench is inclined towards inlet foundation pit; part of underground water is discharged to settler located below inlet foundation pit; sealing shields are mounted in inlet and outlet foundation pits. Then, pipe line is drawn over bottom of trench by means of rope simultaneously closing its bottom by material at high coefficient of sliding over soil, plastic for example; part of pulp is forced to guide trench. EFFECT: reduced energy requirements; reduced resistance to drawing; reduced usage of working agent. 4 cl, 2 dwg
