BUILDING LIFTING AND LEVELING SYSTEM Russian patent published in 2004 - IPC

FIELD: construction equipment, particularly for lifting and leveling of multi-storied building tilted as a result of soil settlement. SUBSTANCE: system comprises power unit including pump station, electric motor, vessel for working hydraulic liquid, electric hydraulic module, which provides common supply of working fluid to executive system members. System also has executive registration unit comprising working members for building lifting and leveling, electric hydraulic valves, motion transducers and control unit. System comprises feedback unit having transmitter and detector for remote sensing of building geometric position and for sensing changes in geometric building shape. Transmitter sends the received information to control unit for correction actuation building lifting and leveling commands in real time. Executive registration unit additionally has pressure transducers for flat hydraulic jack. Control unit is formed as electronic information-computing system equipped with control program, which collects information received from motion transducers and pressure transducers. Information-computing system also has feedback unit, which processes the received information and generates directive commands for electric hydraulic valves. EFFECT: possibility of continuous automated building lifting and leveling, prevention of variance between data determined by motion transducers and real building motion. 14 cl, 8 dwg
