Handan Congtai District Sunghuang Primary School Teaching Building Correction and Reinforcement Project. The building's frame structure suffered from sinking of the left foundation due to insufficient bearing capacity, resulting in an upper deviation of 160mm. The uplift and correction were achieved through the use of a PLC synchronous control system, allowing the teaching building to be used normally. The project was successfully completed between August 16, 2018, and September 1, 2018.
