FIELD: construction.
SUBSTANCE: method comprises installing valving members of pipeline with by-pass lines or branch pipes in passages made of water-proof antierosion boxes filled with soil, stripping a trench with widenings, laying cloth on the walls and bottom of the trench, setting at least one row of antierosion boxes, and laying the pipeline on sliding supports. Before filling the trench with soil, the passage is covered from above with a load-bearing diaphragm. The trench is filled symmetrically from the sides of the load-bearing diaphragm to the pipeline. The by-pass lines within the widenings are inclined at no less than 60° to the horizon.
EFFECT: enhanced reliability.
