Structural detection and reinforcement treatment scheme for a floating underground garage
A underground garage under construction has a floating accident,the up-arching phenomenon of structure was serious,and the structural components were damaged to different degrees.After the accident happened,the temporary emergency measures were taken in time.Through detailed structural detection,the floating influence range of the underground garage was accurately located,and the damage of the affected components was fully grasped.According to the detection results,combined with the original design data and the actual construction situation on site,the floating main factors of underground garage and the mechanism of component damage were analyzed.Targeted reinforcement measures such as grouting,piles replenishment and component replacement were taken to strengthen the structure in the area affected by floating.This project has achieved good results after treatment,and could provide reference for other similar projects.
