Construction method for deformation of supporting stand column in deep foundation pit

The invention discloses a construction method for deformation of a supporting stand column in a deep foundation pit. Belongs to the technical field of building construction. According to the technical key points, the method comprises three major steps, the second step comprises five minor steps, the overall stability of the foundation pit can be effectively enhanced and continuous deformation of the foundation pit can be prevented through early-stage trend analysis, cushion layer pouring acceleration and steel stand column reinforcement. According to the method, collapse of the foundation pit can be effectively avoided by adopting a series of measures, the overall safety, progress and cost goals of a project are protected, a steel stand column reinforcing method is provided, the reference and guidance effects are achieved for follow-up project construction, corresponding reinforcing measures are adopted for deformation of the inner supporting steel stand column, and the construction efficiency is improved.
