LARGE RESERVOIR FOR OIL PRODUCT STORAGE Russian patent published in 2006 - IPC E04H7/02 

FIELD: building, particularly reservoirs with floating roofs for oil product storage.

SUBSTANCE: reservoir comprises wall and bottom connected one to another by compensating member. The compensating member is made as concave corrugated annular member. Partition made as vertical stiffening rib is installed in parallel to wall in air-tight manner so that annular gap is created between the wall and the partition. The gap is filled with elastic rubber oil-resistant material. Cavity between concave annular member, wall and bottom is filled with degassed incompressible liquid and with nonfreezable liquid. Roller frictionless bearings are installed from outer side along the full wall perimeter. Vertical annular stiffening rib is located beyond the bearings so that the stiffening rib, the bearings and the wall define annular gap filled with rubber sealant and then with elastic oil-resistant member.

EFFECT: increased operational reliability along with reduced wall thickness.
