Method for correcting inclined independent bent frame column by vertically jacking and pushing
The invention discloses a method for correcting an inclined independent bent frame column by vertically jacking and pushing, and belongs to the field of engineering building construction. The method comprises the following steps: excavating and removing backfill soil of from periphery of a foundation and a cushion layer; strengthening the root of the inclined independent bent frame column; hanging a correcting device; arranging lifting belts and steel wire ropes on the two sides of the inclined column, and arranging a lifting rope at the upper part of the inclined column; mounting an inclination correcting device; respectively arranging a jack at the bottom corners of the foundation on the inclined side; performing inclination correcting construction, namely, pressing the jacks, starting a crane, and pulling the steel wire ropes and the lifting belts when the inclined independent bent frame column starts to deviate and move; when the original design position range of the inclined foundation is reached, stopping pressing the jacks, placing a steel wedge on the bottom surface of the foundation, taking out the jacks, simultaneously, injecting concrete into the bottom surface of the cushion layer of the foundation and the periphery of the foundation, then removing the crane, and backfilling soil and compacting when the concrete reaches 75 percent of the design strength; stabilizing and observing. According to the method, the inclination of a large-tonnage concrete column can be corrected quickly and accurately, and the concrete column is unlikely to crack to damage the internal structure of the column.
