Construction site tragedy: Two individuals perish due to concrete collapse
A tragic workplace accident occurred on Monday at km62+00 on the Quy Nhơn-Chí Thạnh Expressway in Đắk Lắk Province, resulting in two fatalities and one severe injury. The accident took place in Bình Chính Hamlet, Tuy An Bắc Commune, where workers were building a spillway.
According to initial reports, the formwork structure gave way during the construction process, causing the accident. The workers were spraying concrete from a hose onto manually erected formwork panels when the structure collapsed, leading to the fatalities and injury.
N.B.N., a worker from Xuân Phú Hamlet, Tuy An Đông Commune, fell to the foot of the slope and was buried under the collapsed concrete. T.T.M., a worker from Phú Mỹ Hamlet, Tuy An Bắc Commune, also fell to the foot of the slope and died at the scene. A man from Diêm Điền Hamlet, Tuy An Đông Commune, sustained severe injuries.
The third worker, who sustained severe injuries, was rushed to Phú Yên General Hospital for emergency treatment. Local police are investigating the cause of the accident.
Safety measures for building spillways at construction sites revolve around ensuring structural stability, worker protection, and controlled hydraulic conditions. Formwork structures used in spillway construction must be designed and erected to withstand loads from fresh concrete, workers, and equipment without deformation or collapse. Access to formwork areas should be controlled to prevent falls and injuries, and regular monitoring during concrete placement is essential to ensure formwork is not overstressed.
For concrete spraying (also called shotcrete) in spillway construction, operators must use appropriate personal protective equipment (PPE) and spraying techniques should minimize rebound and dust generation. The work area should be adequately ventilated or water-sprayed to suppress dust, and coordination with formwork teams is required to avoid overloading or damaging form structures during spraying. Equipment like hoses and nozzles must be securely maintained to prevent sudden bursts or misdirection of spray material.
Construction site safety for spillways focuses on preventing structural failure during concrete placement, protecting workers from hazards related to heights, equipment, and materials, and ensuring that hydraulic safety features (like spillway gates) are handled carefully to avoid uncontrolled water releases.
While explicit details on formwork and spraying safety in spillway construction are not exhaustively detailed in the provided search results, the general principles of dam and spillway construction safety involve strict engineering controls, operator training, PPE use, and site-specific measures to handle hydraulic and structural risks.
