How the accident happened
At about 13 o'clock on June 14, 2024, Ou Moujun and 3 workers and excavator drivers went to Tunnel 7 to install the side mold. At about 15 o'clock, the workers used a sling to temporarily lift one end of the longitudinal beam involved (weighing about 560kg) onto the steel bar protruding 1.8 meters from the ground on the side of the side of the side of the mold against the opening. Due to the poor stability of the sling, the workers then switched to using wire ropes for lifting. Before lifting again, Ou's military steel bar is fixed by hanging the cable eye of the wire rope and the lifting lug of the longitudinal beam (no anti-detachment device is set). When the longitudinal beam was hoisted to the target height, Ou Moujun and the workers worked together to support the longitudinal beam with their hands to align it with the trolley side mold. In the process of pushing, the steel bar that hung the wire rope involved fell off, causing the involved longitudinal beam to fall to the ground and hit the head of Ou Moujun under the longitudinal beam.

Direct cause analysis
1. The workers involved illegally used steel bars to replace special fixtures to fix the lifting points through the lifting lugs of the longitudinal beam and the cable eyes of the wire rope; Because the steel bar is not provided with an anti-detachment device, there is a risk of slipping;
2. The workers involved have weak safety awareness, and venture into the hovering longitudinal beam to push the longitudinal beam under it during the lifting process;
3. In the process of the worker's pushing, due to the tilting of the longitudinal beam, the steel bar slipped and fell, and the longitudinal beam involved lost the steel bar and fell and injured the worker, causing an accident.
