Title:
METHOD FOR INCLINATION RECTIFICATION BY ROTATIONAL DISPLACEMENT OF BUILDING UNDERPINNING FOUNDATION
Document Type and Number:
WIPO Patent Application WO/2022/032994
Kind Code:
A1
Abstract:
A method for inclination rectification by rotational displacement of a building underpinning foundation, relating to the field of inclination rectification for buildings. The method comprises: excavating an annular working pit around a building; establishing a track foundation having a spatial curved surface, and laying a displacement track; arranging underpinning beams for the inclined building so as to construct an underpinning foundation; and disconnecting independent footings (4) and frame columns (5), and then driving rotational displacement of the building along the displacement track by means of the underpinning foundation so as to achieve effective inclination rectification in a three-dimensional spatial trajectory. For the overall inclination of a building which may be generated in any direction, inclination rectification is achieved by means of rotational displacement along a three-dimensional spatial curved surface track, so as to overcome the limitation at present of it being difficult to carry out inclination rectification on an inclination direction and a main axis arrangement direction by means of two-dimensional path inclination rectification; and after the inclination rectification, a self-recovery structure that can carry out seismic isolation on a seismic acting force in any direction can be formed.
