| Abstract: | quality defects reinforcement. platform, concrete. In a foundation project, local concrete strength fails to satisfy the design requirements due to of commercial concrete, and superstructure construction must be stopped for foundation Steel support, pinning is adopted in the foundation where needs to be reinforced. Bearing ground beam and bottom plate concrete are chiseled and steel bars are replaced before re-pouring of Monitoring is strengthened during reinforcement to successfully solve quality accident and guarantee continuous construction of superstructure |
