accident happened
on May 6, 2024, when Li Bo, a worker of Hebei Yaoqi Company, was assembling the accident corridor, he found that the large truss of the accident corridor was deformed, and reported to Li Zhijun, the company's site manager, and Li Zhijun reported to Sun Ketao, the site manager of Anhui Climbing Company. Sun Ketao instructed Li Zhijun to correct the deformation part of the large truss with a Jack, but there was still deformation after correction.
On May 16, when Li Zhijun was organizing the hoisting of the accident corridor, he found that the screw holes connecting the base of the corridor and the shoulder pad of the shaft column did not correspond, and the screws could not be tightened. On May 22, Wang Guojun of Wujianyuan Company found that the screws of the accident corridor were not fastened during the inspection and asked Li Zhijun to rectify them. At about 7 o'clock
on May 24, Li Zhijun called the workers of Hebei Yaoqi Company to hold a morning meeting, arranged workers Li Xue and Feng Yanpeng to be responsible for correcting the screw holes in the accident corridor, and arranged workers Wang Jinglou, Duan Xudong and Xin Xiaoli to be responsible for the edge welding of the accident corridor. Subsequently, the workers began to prepare the tools and materials needed before the construction work. 00, the workers entered the accident corridor one after another. 30, Wang Jinglou, Duan Xudong and Xin Xiaoli were welding in the accident corridor. Li Xue and Feng Yanpeng were ready to correct the screw hole position. Because they did not have the experience of using jacks to correct the screw hole position, they consulted Wang Jinglou and, according to his guidance, removed 14 high-strength bolts connecting the base of the accident corridor and the shoulder pad of the ③ axis column. The seven-character frame was welded to place the Jack, and when the Jack was ready to be used, the corridor collapsed instantly. At the time of the
accident, four construction workers in the corridor fell with one end of the corridor of the ②-③ axis section: Wang Jinglou's face was close to the ground, his helmet was separated from his head, and he did not wear a safety belt; Feng Yanpeng's face was upward, his helmet was not separated from his head, and he did not wear a safety belt; Duan Xudong's face was close to the corridor walkway board, his helmet was separated from his head, and he did not wear a safety belt; Xin Xiaoli sat in the corridor, his helmet shell fell off, and he did not wear a seat belt.
