FIELD: construction.
SUBSTANCE: invention relates to construction of pipelines, namely in oil-gas industry, and can be used at execution of construction and repair works on oil and gas pipelines. The pipeline routing method involves routing of an insulated pipeline into a trench on a preparation layer treated by a modifying agent, back filling of the pipeline with a filling layer treated by the modifying agent, with further formation of embanking. As a modifying agent a product of reagent deactivation of oil-contaminated production wastes and soils is used, which contains calcium hydroxide and carbonate in the amount of 15-45 wt % of the soil weight. At treatment of soil there introduced is a solution of sodium methyl siliconate in the amount of 0.2-1.0 wt % of soil weight in terms of the basic substance.
EFFECT: reduction of corrosion activity of preparation and filling soils at pipeline routing.
