FIELD: construction. ^ SUBSTANCE: system to lift and balance buildings comprises a hydraulic system made in the form of flat hydraulic jacks installed in jack niches and connected to a pump station with the help of the main hydraulic liquid manifold and connected by electric hydraulic valves, an internal monitoring system made of small displacement sensors, an external monitoring system made of light-reflecting marks, geodesic centres and coordinates of detection measurement facilities, and also a personal computer and a unit of hydraulic system control. One of jacks in a jack niche is a master one. By means of an electric hydraulic valve it is connected into the main hydraulic liquid manifold. Other jacks installed in the same jack niche are connected by a liquid manifold to a master jack. A hydraulic check valve is installed at the inlet of each jack to the liquid manifold. ^ EFFECT: increased range of the system operation, reduced time required to balance buildings. ^ 2 dwg |
