SEISMIC RESISTANT FOUR-PILE MOBILE PIPELINE SUPPORT AND DAMPER DEVICE FOR THE SEISMIC RESISTANT FOUR-PILE MOBILE PIPELINE SUPPORT Russian patent published in 2018 - IPC F16L3/20 F16L3/10 

FIELD: construction.

SUBSTANCE: group of inventions relates to the field of construction of aboveground pipelines and can be used for aboveground laying of pipelines in seismically hazardous areas. Disclosed pipeline support consists of a supporting grillage table fixed to four piles through the bearing sleeves with the movably mounted on it support foot, pivotally connected to the support socket, provided with a side support plate, of at least two half-clamps detachably connected to the support socket. On each pair of piles located on one side of the pipeline, a damper device is installed at the level of the side support plate socket. Said damper comprises interacting flexible and friction assemblies. Flexible assembly is formed by installed at the ends of at least two rods centered on with a flexible damper. Friction unit includes at least four friction half couplings fixed to the damper device carrier beam in pairs oppositely to each other, at least two stems, each of which is mounted between a pair of friction half couplings. Damper device carrier beam is mounted on piles by means of two shells, and the friction half couplings are made with possibility to restrict movement of the stems in the horizontal transverse direction relative to the axis of the pipeline.

EFFECT: as a result damping of seismic effect on support pile foundation and pipeline in the preset design modes in horizontal transverse direction is achieved.
