Sheet Pile Flood Defence Installation
Sheet piles are used extensively in flood defence construction to create impermeable barriers along rivers, estuaries, and coastal frontages. Installation involves heavy lifting, vibration driving, and working near open water. The combination of deep excavation, water proximity, and heavy plant creates significant risks for the installation team. This talk covers the key safety controls for sheet pile flood defence works.
Key Hazards
Drowning from falling into adjacent watercourse during installation
Crush injuries from sheet piles swinging during lifting and pitching
Hand-arm vibration exposure from prolonged vibro-hammer operation
Noise-induced hearing loss from impact or vibratory driving methods
Control Measures
- Ensure all workers near open water wear personal flotation devices at all times.
- Establish exclusion zones around the pile driving area and the crane swing radius.
- Use tag lines to control sheet pile swing during lifting and positioning.
- Monitor hand-arm vibration exposure and rotate operatives to limit daily trigger time.
- Provide hearing protection appropriate for the driving method and monitor noise exposure levels.
- Inspect the crane, vibro-hammer, and lifting accessories at the start of each shift.
- Brief all operatives on the water rescue plan and location of rescue equipment before work starts.
- Ensure the piling platform and crane hardstanding are designed for the actual ground conditions.
- Coordinate with the Environment Agency regarding in-river working periods and environmental permits.
Remember
- Wear a personal flotation device at all times when working near open water
- Maintain exclusion zones around the pile driving area and crane swing radius
- Use tag lines to control sheet pile swing during every lift and pitching operation
- Monitor vibration exposure and rotate operators to limit daily trigger time
- Know the water rescue plan and location of rescue equipment before starting work
