EARTHQUAKE-RESISTANT PIPELINE Russian patent published in 2016 - IPC E02D27/46 

FIELD: construction.

SUBSTANCE: invention can be used in construction of main pipelines in seismic regions. Earthquake-resistant pipeline includes a pipe, concrete base, support plates installed above the concrete base with a gap, and intermediate elements arranged between concrete base and support plates. In the concrete base there are at least two recesses with metal cups having circular bull-heads sides facing upwards. Support plates are bent in the form of a cup, shaped like the concrete base cup, their boards is aligned with the concrete base cup to form a cavity inside of which ball-shaped intermediate elements are installed. Pipeline is additionally equipped with a band and support bed, between which the support damper is installed. Support bed is attached to support plates by means of vertical stiffness ribs.

EFFECT: high earthquake resistance of pipeline at considerable seismic oscillations, simplified design, reduced labor input, higher reliability.
