A pipeline geological disaster protection device and its installation and use method

Abstract

The invention discloses a pipeline geological disaster protection device and an installing and using method thereof. The device comprises a supporting base, a lateral buffering wall, pipeline fixing clamps and a buffering layer. The supporting base comprises a sliding rail structure, a first base, a plurality of pressure springs, a plurality of stable pull rods I, a plurality of stable pull rods II and a second base. The lateral buffering wall comprises an L-shaped steel plate and a plurality of pressure springs. Through the arrangement of the compressible supporting base and the sliding railstructure, the lateral buffering wall and the pipeline fixing clamps on the supporting base, when a pipeline is mostly subjected to inclined impact force from landslide and falling stone, sliding in the horizontal and vertical direction can be achieved within the pipeline deformation extreme range, the supporting base and the lateral buffering wall are used for bearing component force in the horizontal direction and the vertical direction and absorbing energy, good pipeline landslide and falling stone impact preventing effects are achieved, meanwhile, cost is low, arrangement is flexible, andconstruction is convenient.

Description

Technical field [0001] The invention relates to the field of pipeline protection, in particular to a pipeline geological disaster protection device and an installation and use method thereof. Background technique [0002] my country's vast area and uneven distribution of resources determine the wide distribution of long-distance oil and gas pipelines. Pipelines passing through mountainous areas are often damaged by small-scale landslides or rock falls due to the characteristics of climate and geological conditions. [0003] At present, the prevention and control of geological disasters such as landslides and rockfalls is mainly considered from the perspective of slope fixation, which is costly and difficult to construct. The existing technology also aims at the protection of the pipeline body, which uses large incompressible fixed support seats and horizontal The slipping method protects the pipeline. Its shortcomings are very obvious. It can only alleviate part of the damage cause...

Problems solved by technology

[0003] At present, the prevention and control of geological disasters such as landslides and rockfalls is mainly considered from the perspective of slope fixation, which is costly and difficult to construct; in the prior art, there is also protection for the pipeline body, which uses a large incompressible fixed support seat and a horizontal The method of sliding to protect the pipeline has obvious disadvantages. It can only alleviate the damage of part of the horizontal impact force, while landslides and rockfalls are mostly oblique impact forces, so the vertical impact force cannot be relieved and absorbed. The protection of the pipeline Poor effect and high cost
