Problems solved by technology

However, these measures also have negative factors, such as: improving the pipe ductility or increasing the pipe wall thickness will greatly increase the amount of high-grade steel or the weight of the pipe, which will increase the cost and highlight the economic weakness; correct selection of the fault plane and pipe axis The angle between them can make the pipeline under tension during the fault movement and avoid compressive buckl

Abstract

The invention relates to pipeline construction, in particular to an anti-seismic protection structure of a micro-pile frame pipeline. The anti-seismic protection structure comprises top plates and micro-piles driven into soil, and the micro-piles are fixed in the top plates; a space frame structure is formed by the micro-piles and the top plate overall, and the top plates are arranged at the footof a mountain; the frame structure used for arranging a pipeline in a sleeving mode is formed by one top plate and at least four micro-piles; and the frame structure is a protective unit, and the protective units are arranged in a certain direction to form a channel used for protecting the pipeline. Through arrangement of the anti-seismic protection structure of the micro-pile frame pipeline, longoil and gas pipelines laid at the foot of the mountain are protected, so that damage or larger deformation risks of the pipeline are reduced under the strong earthquake action.

Description

technical field [0001] The patent of the present invention relates to pipeline construction, in particular to a micro pile frame type pipeline anti-seismic protection structure. Background technique [0002] Pipeline transportation is the main means of energy transportation, and it occupies a very important position in modern industrial production and people's life. It has been widely used in transportation of water, oil, gas, communication, power supply, transportation and drainage. For long-distance oil and gas pipelines, due to the long pipeline and the complex conditions of the pipelines passing or crossing, different sections of the pipeline suffer from different seismic effects, and the damage state and degree of damage of each pipeline section are different. For the pipelines laid along the slope foot of the mountain, under the action of an earthquake, a certain section of the pipeline may be damaged due to the thrust of the landslide, which will have an adverse effec...
