The invention discloses a self-balancing system of a buried pressure-bearing large-diameter socket connection pipeline and a verification method thereof, the self-balancing system comprises a pipeline, a bearing platform plate, at least one pair of retaining piers and a foundation, the bearing platform plate is arranged below the pipeline, the pipeline comprises a non-straight section and a straight section, the at least one pair of retaining piers is arranged at the end part of the straight section of the pipeline. The non-straight section and the straight section are in socket connection, and the foundation is arranged below the bearing platform plate in the laying direction of the pipelines. According to the self-balancing system of the buried pressure-bearing large-diameter socket connection pipeline, the self-balancing stress system is utilized, acting force generated by fluid on the pipeline is converted into force inside the system, counter force is provided through the rigidity of all the components, socket connection is prevented from being damaged. The self-balancing effect is achieved, stress is more reasonable, and cost is lower.
Description
technical field [0001] The invention belongs to the technical fields of petrochemical industry, natural gas, and municipal water supply and drainage, and more specifically relates to a self-balancing system and a verification method for buried pressure-bearing large-diameter socket connection pipelines. Background technique [0002] With the continuous development of industrialization, energy sources are increasingly diversified to meet the needs of economic development and environmental protection. Petrochemical, natural gas, municipal water supply and drainage and other application pipeline transportation, such as the heavy construction of liquefied natural gas receiving stations, usually use seawater as the heat source for natural gas gasification, and seawater pipelines are mostly made of glass fiber reinforced plastics due to the corrosive effect of seawater media. The continuous emergence of new production processes has made the application of large-diameter buried pre...
