AI Technical Summary
The existing buffer guardrails in pumped storage power stations are prone to causing secondary injuries to construction workers who fall, mainly because they have a single function and cannot effectively mitigate the risk of secondary falls when the center of gravity is unstable.
A comprehensive protection system was designed, including a buffer guardrail, traction steel cable, buffer net, limit plate and safety rope. The system prevents construction workers from falling again by using the inclined buffer net, the limit plate and the safety rope to buffer the fall.
It effectively mitigated the impact of the workers' fall, prevented secondary falls, and ensured the safety of the workers.
