Abstract
1. Способ ремонта потенциально опасного участка газопровода с повышенным уровнем напряженно-деформированного состояния, заключающийся во вскрытии газопровода и оценке его напряженно-деформированного состояния, отличающийся тем, что, увеличивая локальную плотность грунта под газопроводом и перераспределяя нагрузку, корректируют его высотное положение, что приводит к увеличению радиуса изгиба и, следовательно, снижению изгибных напряжений.2. Способ ремонта потенциально опасного участка газопровода по п.1, отличающийся тем, что протяженность распределенных усилий в местах минимального радиуса изгиба участка газопровода составляет не менее 0,8 общей длины вскрытого участка.1. A method of repairing a potentially dangerous section of a gas pipeline with an increased level of stress-strain state, which consists in opening the gas pipeline and assessing its stress-strain state, characterized in that, by increasing the local density of the soil under the gas pipeline and redistributing the load, its altitude position is adjusted, which leads to to increase the radius of bending and, consequently, reduce bending stresses. 2. A method of repairing a potentially dangerous section of a gas pipeline according to claim 1, characterized in that the length of the distributed forces at the minimum bending radius of the gas pipeline section is at least 0.8 of the total length of the opened section.
