Description

Technical Field

[0002] For waterfront buildings, due to the erosion of the foundation by nearby water all year round, the foundation is prone to slip and uneven settlement, resulting in the sinking, tilting or torsional deformation of the waterfront building. The additional stress will cause cracks in the building, endangering the safety of surrounding residents.

[0003] In the prior art, a Chinese patent with the publication number CN1082598C provides a method for jacking and rectifying broken columns of a building. By setting a multi-point jacking structure at the column position with a larger settlement amount, setting a simulated hinge support at the column position that does not need to be jacked, then cutting off the column at the jacking column position, and then implementing synchronous jacking according to the principle of keeping the upper structure in rigid body rotation, so that the building rotates around the simulated hinge support, and the rectification and repair of the building are realized to a certain extent. However, this rectification and repair form is mainly aimed at the unstable foundation conditions such as the sinking and tilting of the building, and the torsional reset of the building cannot be realized. For the torsional deformation of the building, the existing rectification process generally uses channel steel as the diagonal support to assist in fixing the frame structure of the building, and then uses the channel steel near the ground as the reaction fulcrum, and realizes the torsional reset of the building by the way of pushing and resetting. However, this rectification method cannot effectively rectify the overall torsional deformation of the building, and there are certain limitations.
