VIBRATION-INSULATED FOUNDATION WITH PNEUMATIC VIBRATION INSULATION SYSTEM Russian patent published in 2017 - IPC E02D27/44 

FIELD: construction.

SUBSTANCE: vibration-insulated foundation with a pneumatic vibration insulation system includes a foundation bath filled with a compressed gas, a support block arranged in the foundation bath, an elastic element made in the form of a torus filled with a compressed gas and located between the side surfaces of the foundation bath and the support block, and a supply pipeline of the compressed gas. The support block is made hollow with throttling openings communicating its cavity with the foundation bath cavity and with the torus cavity. The compressed gas supply pipeline is brought into the support block cavity and to the autoregulator for maintaining the upper surface level of the support block, an additional damping device is rigidly fixed to its lower surface, made hollow in the form of a framework having an equidistant shape with the support block, located between the support block and the foundation bath bottom, on which the framework rests through mesh washer dampers and the cavity of which is connected to the support block cavity through a throttling opening.

EFFECT: increasing the efficiency of vibration damping, reducing dynamic loads on the lower structure of the building foundation.
