HYDRO-CIRCULATION FOUNDATION ON SWINGING SUPPORTS Russian patent published in 2022 - IPC E02D27/34 

FIELD: construction.

SUBSTANCE: invention relates to construction, namely the construction of foundations for multi-storey buildings erected in seismic regions. The hydrocirculation foundation on swinging supports consists of upper and lower foundation plates, swinging supports with spherical support surfaces are located between the upper and lower foundation plates in spherical recesses, they are disc-shaped rubber-metal shock absorbers that are oriented towards each other along the bottoms, and the ends facing each other their sections are made with grooves forming a spherical cavity partially filled with liquid. The upper and lower sections of the oscillating bearings have movement limiters relative to each other. The lower foundation slabs are supported on the T-shaped foundation structure through a support gasket with the possibility, together with the upper foundation slab, of forming a central chamber filled with liquid. The vertical walls of the central chamber have grooves for the flow of liquid into the left and right paired chambers, the outer walls of the paired chambers are made with an axial spring mechanism for the possibility of movement, rotation about the axes of the swinging supports and shovels to dampen torsional and translational-rotational vibrations, a gap is made between the outer walls of the chambers and the swinging supports, which is set taking into account the level of frequently repeated technological, vibrational and seismic effects. The pressure in the paired chambers can be changed using adjustable valves, the lower and upper foundation plates are made with vibration limiters relative to each other.

EFFECT: increasing the stability of the building due to the movement and circulation of fluid in paired chambers, increasing the stability and reliability of the operation of the building with a wide range of changes in ground vibrations during earthquakes of medium intensity (7-8 points) due to the fact that the underground part of the building is equipped with a hydrocirculation foundation system on swinging supports.
