Abstract
Depressurization of underground pipelines transporting water, wastewater, oil products, gas, coal pulp and other substances is fraught with product losses, flooding of territories, environmental damage, deterioration of the sanitary and epidemiological situation, the formation of explosion and fire hazardous situations. Rapid detection, sizing and elimination of product leaks is an urgent task. In the article, this problem is considered as applied to water-bearing communications.
Based on the proposed physical picture of the outflow of water from the damaged pipeline wall and its subsequent movement in the thickness of the surrounding soil, a mathematical model of the process was obtained. Depending on the water pressure in the damaged pipeline, the size of the emergency hole in the pipeline wall, the depth of its laying and the water permeability of the soil, four options for the possible nature of the manifestation of a leak from an underground pipeline are established: with a concentrated and dispersed exit to the earth's surface, with water resorption in the drainage by adjacent underground utilities.
