THREE-DIMENSIONAL FOUNDATION PLATFORM CONNECTED TO TANK TO FORM CLOSED SYSTEM TO BE BUILT ON WEAK, PERMAFROST, HEAVING SOIL AND IN SEISMIC ZONES (VARIANTS) Russian patent published in 2006 - IPC E02D27/32 E02D27/34 E02D27/35 

FIELD: foundations for special purposes, particularly foundation platforms connected to tanks.

SUBSTANCE: reinforced concrete beams or trusses are installed between reinforced concrete panels of upper and lower belts of three-dimensional platform. Reinforced concrete beams or trusses have inclined upper face and are connected one to another in center by monolithic rigid core. The reinforced concrete panels have trapezoid or segmented shape in plane. Reinforced concrete beams or trusses with key connections are located in parallel between reinforced concrete panels of upper and lower belts. Tank walls and coverings have arched structure shaped as prismatic polyhedron inscribed in cylindrical surface defined by square parabola or another curve with generatrices parallel to beams or trusses of three-dimensional foundation platform.

EFFECT: increased structural efficiency due to increased reliability of three-dimensional foundation platform, reduced metal consumption and labor inputs.
