PADDING STRUCTURE Russian patent published in 2015 - IPC E02D23/12 

FIELD: construction.

SUBSTANCE: invention relates to padding structures for placement of object on a seabed or river bed. The padding structure for placement of an object installed on a padding structure, on a seabed or river bed containing at least one unseparable motionless buoyancy device and at least one unseparable mobile buoyancy device with variable buoyancy and the hard control surface, and the unseparable mobile buoyancy device is designed with a possibility of movement with reference to the unseparable mobile buoyancy device for change of the position of the hard control surface and control of the position of the buoyancy center with reference to the position of the center of gravity.

EFFECT: technical result consists in improvement of stability of a padding structure, ensuring controllability at immersion or emersion due to control of position of the buoyancy center with reference to the position of the center of gravity.
