Due to the effect of the tip feather and spiral blade attached to the steel pipe, large vertical support force and the pull-out strength is obtained, friendly to the environment is a strong method to the earthquake.
Features of construction method
- Large vertical support force and pull out strength.
- Due to the effect of the tip blades and spirall shaped baldes, it exhibits a large veertical support force and pull out strength resistance.
- Low noise, low vibration.
- By the rotary penetratoin method, low noise/ low vibration construction is performed.
- Pull out possible.
- Pull out can be removed by rotating the pile in reverse direction. Also effective for temporary construction.
- Unleasing earth and soil.
- Realizing of unleasting construction without muddy residue and remaining soil.
- Can be constructed with general purpose machine.
- It is possible to construct with a general purpose machine such as a small piling machine, three point support anti-impact machine, all round turning machine.
