METHOD TO INSTALL UNDERGROUND PIPELINE IN ZONES WITH HIGHER SEISMICITY Russian patent published in 2012 - IPC F16L1/28 

FIELD: construction.

SUBSTANCE: method uses accessories that compensate for seismic loads arranged in the form of boards placed along the length of a pipeline with identical intervals and placed onto the surface of the ground. Boards are fixed in the ground with the help of four supports placed in it and with divergence away from the boards. On each board with the help of a hinged joint there is a double-arm lever installed as capable of rotation in a vertical plane stretching via a longitudinal axis of the pipeline. Its one arm is aligned normally to the longitudinal axis of the pipeline and is hingedly connected with a band fixed on it, and the second arm of the lever is aligned at the right angle to the specified arm, directed along the axis of the pipeline and is hingedly connected to a traction rod. The traction rod is aligned as inclined at the angle α equal to 45 degrees to the longitudinal axis of the pipeline and is hingedly connected to the other band also fixed on the pipeline.

EFFECT: higher reliability of a pipeline, simplification of its installation, simplified and cheaper operations related to repair and prevention of pipeline equipment in process of its operation.
