Problems solved by technology

[0005] However, most of the current anti-seismic methods only focus on the destructive effect of the pipeline under the permanent displacement of the ground, and do not consider the influence of the seismic fluctuation effect, and the influence of the seismic fluctuation effect in some cases cannot be ignored. Therefore, it is necessary to invent a An anti-seismic device that resists permanent displacement of the ground while reducing the effects of seismic fluctuations

Abstract

The invention provides an anti-seismic device and an anti-seismic system of a buried pipeline. The device comprises a culvert and a sliding supporting structure. The culvert is buckled in a pipe ditchto form a space structure, and the sliding supporting structure is arranged in the formed space and can laterally slide within a certain range perpendicular to the buried pipeline axis direction. When the earthquake happens, great relative displacement of the surrounding soil body can be generated due to faulting, and within a certain range, the buried pipeline arranged on the sliding supportingstructure can laterally slide along with movement of the soil body. The sliding supporting structure is internally further provided with a spring structure with high elasticity, and deformation of theburied pipeline can be partially absorbed by the spring structure under the earthquake wave motion effect. Thus, according to the provided scheme, within a certain range, lateral deformation generated to the buried pipeline due to faulting can be effectively avoided, and influences on the buried pipeline due to the earthquake wave motion effect can be reduced.

Description

technical field [0001] The present application relates to the anti-seismic field of buried pipelines in fault areas, in particular to an anti-seismic device and an anti-seismic system for buried pipelines. Background technique [0002] As a national strategic energy source, oil and natural gas have been in increasing demand in the past few decades, which has promoted the continuous construction of large-scale gas transmission pipeline projects such as my country's West-to-East Gas Transmission, Sichuan-East Gas Transmission, and New Guangdong-Zhejiang. Avoid crossing geological disaster areas, especially earthquake fault areas, and pipelines often have large deformations and fail under the action of earthquakes, making the research on anti-seismic technology of pipelines one of the key issues in pipeline engineering design. [0003] There are two external reasons for the destruction of buried pipelines under earthquake action: one is site damage, that is, permanent displaceme...
