Description

The antishock device and vibration prevention system of buried pipeline

Technical field

This application involves fault zone buried pipeline seismic resistance field more particularly to the antishock devices and antidetonation of a kind of buried pipeline System.

Background technology

As the national strategy energy, interior demand is continuously increased oil and gas in the past few decades, promotes me The continuous construction of the large-scale gas pipeline projects such as state transfers natural gas from the west to the east, river gas east is sent, new Guangdong Zhejiang, since long-distance pipe is inevitable Ground passes through geological disaster area, especially earthquake fault area, and pipeline often will produce large deformation under geological process and fail, and make Obtaining the anti-seismic technology research of pipeline becomes one of the Important Problems of pipeline engineering design.

There are two types of the external causes that buried pipeline is destroyed under geological process：One is place destructions, the i.e. permanent position in ground It moves, is generally caused by fault movement；Another kind is seismic wave effect, i.e., ground caused by the seismic wave released by focus Movement.The coverage that place is destroyed is although limited, but ground can be made to generate larger relative displacement to a very small extent, So that buried pipeline is moved with surrounding soil, rupture occurs so as to cause the buried pipeline intersected with earthquake fault area, breaks It splits and fails, harmfulness is very big.The spread scope of seismic wave is very wide, but its influence is smaller compared with place is destroyed, if burying Ground pipeline is in meizoseismal area, and influence of the seismic wave to buried pipeline can not still despise.

Currently, being primarily present two class buried pipeline antidetonation corrective measures：Reduce pipe-soil interaction and raising pipeline is strong Degree.In pipe-soil interaction, most ways are backfilled to pipe trench using fluffing of moulding sand soil, and fluffing of moulding sand soil can effectively reduce pipe-soil Between frictional force, therefore the strain value of pipeline under faulting can be substantially reduced；Another way will be broken using geotextiles Floor area duct wraps get up, and this method can equally reduce rubbing action of the soil to pipeline.In terms of pipeline strength, height is used Grade of steel pipeline, the intensity of pipeline can be effectively improved by increasing pipeline wall thickness or wrapping up composite material etc. in pipeline outer wall.It does above Method reduces destruction of the tomography to pipeline to a certain extent, belongs to antidetonation mitigation strategy.

However, majority anti-shock methods do not consider only for the destruction in pipeline under the permanent displacement of ground at present The influence of seismic wave effect, and the influence of seismic wave effect in some cases still be can not ignore, therefore one kind need to be invented Ground permanent displacement can be resisted, while the antishock device of seismic wave effect can be reduced again.

Therefore, the destruction to pipeline of seismic wave and ground permanent displacement for how reducing earthquake generation is this field there is an urgent need for The technical issues of solution.
