FIELD: construction.
SUBSTANCE: method for installation of pipeline complex for water-, gas- and heat supply, sewage, telecommunication and electrical cables and closed horizontal drain includes digging the main trench by means of earth-moving machine with simultaneous formation of longitudinal niches in one or both side walls of the main trench, transverse axes of which are inclined relative to plane of side walls of the main trench. Further each of pipelines is installed into its personal longitudinal niche, rigidly fixed and backfilled from earth deposit.
EFFECT: increased efficiency, simplicity and safety of method.
