Robotic system for lifting and leveling multistorey buildings

Abstract

Abstract Currently, the problem of restoring the service reliability of residential multi-storey buildings in ultimate limit state is an urgent problem. Basically, buildings that are in the emergency group have an excess of standard building tilt. This problem is solved, most effectively, by lifting and leveling by means of the hydraulic robot-based system. In the aforementioned system, including the hydraulic part, a system of sensors, control of geometric characteristics, and a management software, when lifting a building, the comparison of measurement results from two groups of sensors is performed. The first group of sensors is linear displacements installed in the area of ​​the separation cavity and monitoring the amount of movement of the building relative to its base. The second group of sensors – building tilts installed on horizontal and vertical bearing structures of buildings, monitor the change in the leans and tilts of building structures. The software provides a comparative analysis of two information flows, evaluates their identity and adequacy, and performs a control action on the hydraulic part or on the continuation of the lifting procedure, or on the termination of this action.
