METHOD OF CONTINUOUS BUILDING LIFTING AND STRAIGHTENING Russian patent published in 2004 - IPC

FIELD: building, particularly for recovering operational reliability of building during repair thereof by building lifting and straightening along with following building structure reinforcement.

SUBSTANCE: method involves investigating and preparing building, including producing and mounting force belts and jack recesses, installing jack system having flat jacks and pumping plants, inner control system having resistance slight motion transducers; forming outer control system; actuating jack system for building separation from foundation and for cyclic straightening thereof; determining building lifting speed for each jack recess in each straightening cycle from given relations; calculating rotational frequency ω of electric motor of each pumping plant and generating command for building lifting; actuating jack system and timer; performing control of each electric motor by tachometers installed directly on electric motor; carrying out control of jack recesses lifting by means of inner control system and switching off jack system at the expiration of ∂t time period.

EFFECT: possibility of uniform building straightening without deformation and damage thereof.
