Example is applied, shall fall in the protection scope of this application.
For convenience of explanation, the size for the different layer and region that zoomed in or out, so size as shown in the figure and ratio
Actual size might not be represented, does not also reflect the proportionate relationship of size.
Fig. 1 is the schematic diagram of the protective device for the buried pipeline that one embodiment of the application provides, as shown in Figure 1, the device
Including：The foam block 102 being pressed on buried pipeline 101；
Foam block 102 and buried pipeline 101 are respectively positioned on earth's surface hereinafter, being filled around foam block 102 and buried pipeline 101
There is the fluffing of moulding sand native.
In the present embodiment, as shown in Figure 1, buried pipeline 101 can be pass through fault zone long distance delivery oil or
The pipeline of person's natural gas, pressure sets foam block 102 on buried pipeline 101, and foam block 102 and buried pipeline 101 are respectively positioned on
Earth's surface is hereinafter, fill fluffing of moulding sand soil around foam block 102 and buried pipeline 101.Specifically, the making material of buried pipeline 101
The steel of Hi-grade steel are selected, to increase the rigidity of buried pipeline, to mitigate injury of the ground moving to buried pipeline.It is burying
Pipeline 101 surrounding in ground fills fluffing of moulding sand soil, since friction is small between fluffing of moulding sand soil and buried pipeline 101, can also reach and subtract
To the effect of the injury of buried pipeline when light ground moving.Fluffing of moulding sand soil is filled around foam block 102, it can be by foam block 102
It is fixed on buried pipeline 101, keeps relative position between foam block 102 and buried pipeline 101 constant.When reversed fault occurs
When, whole beam type buckling can occur for buried pipeline 101, and invade in foam block 102, and the making material of foam block 102 can
To select expandable polystyrene (Expandable Polystyrene, abbreviation eps foam block), do not limit herein.
