FIELD: construction; laying of mains on soft ground. SUBSTANCE: on forest= covered sections along mains route trees are cut to provide designed height of stumps, and trench is dug out from side of pipeline under base of passageway in zone of maximum loads and soil-filled vertically arranged water permeable containers are laid in trench in one tier and are fixed by cross tying by sling members, and cut wastes and bush are placed between stumps. Upper vegetable soil layer is removed over trench of pipeline and over soil heap and is placed over cut waste and diaphragm made of long-lasting industrial fabric is placed in base of technological passageway. Long-cut members are fitted in eyes on edges of load-bearing diaphragm. Said is laid on load-bearing diaphragm, and upper bases of water permeable containers are arranged at one level coinciding with surface with peat deposit bed or projecting over said surface. Variants of making of bases of technological passageway are provided in description of invention. EFFECT: reduced time taken for laying of pipeline. 6 cl, 2 dwg |
