[0002] With the development of cities, the use amount of natural gas also increases, in order to meet the use demand of city natural gas, it is necessary to construct natural gas storage facilities (LNG storage tanks) to realize the regulation effect of reserving natural gas at night to meet the use amount of natural gas in the daytime. In the construction of the natural gas storage facilities, pipelines are often laid to connect the natural gas storage facilities and the main pipeline, and when the pipelines are transported to the construction site and not laid and constructed, the pipelines cannot be directly placed on the site of the construction site, and rubber pads and the like need to be used to cushion, protect and support the pipelines.

[0008] Step two, pipe body placement: the natural gas pipe is placed in the semicircular rubber pad, the middle part of the rubber pad elastically deforms and is concave to accommodate the overall elastic deformation amount of the rubber pad, so that the instantaneous impact extrusion of the natural gas pipe placed on the rubber pad will not elastically deform outward.

[0009] Step three, second damping adjustment of the damping member: after the natural gas pipe is placed stably and stationary, the damping member in the middle of the bottom of the rubber pad is adjusted to have the same damping as the two damping members on the outside, and the extension and retraction amounts of the telescopic inclined support member and the telescopic support member are adjusted to supplement the contact support surface of the rubber pad to the natural gas pipe.

[0021] The beneficial effects of the present application are that the damping of the same axial direction to the damping member in the middle of the rubber pad bottom is adjusted low through the medium filling port, and the damping of the same axial direction to the two damping members outside the rubber pad bottom is adjusted high; when the natural gas pipe is placed in the semicircular rubber pad, the middle of the rubber pad appears elastic and concave to accommodate the overall elastic deformation of the rubber pad, so that the instantaneous impact of the natural gas pipe placed on the rubber pad will not cause elastic deformation outward to solve the problem of elastic deformation of the rubber pad along the axial direction of the pipeline to the both ends, and the pipeline will be placed for a long time.
