PROTECTION OF OBJECT PUT INTO GROUND AGAINST MULTIPLE SEISMIC ACTION AND GEAR FOR ITS REALIZATION Russian patent published in 1997 - IPC

FIELD: construction industry. SUBSTANCE: proposed protection includes compliant facing in the form of large-sized bellows, cavities in ground meant for location of protected object and pendulum suspensions incorporating dampers- shock absorbers by which object is hanged in cavity from supporting ring. Large-sized bellows does not screen seismic action but evades from it deforming in any direction. Thanks to this circumstance bridging effect is realized in ground around cavity and cavity does not collapse but only deforms. Seismic action flows over cavity. Ground vibrations together with cavity are suppressed by pendulum suspensions and dampers-shock absorbers and practically do not reach protected object. This effect is achieved by way of adjustment of dampers to overload to protected object specified in advance. EFFECT: enhanced reliability of protection. 15 cl, 15 dwg
