Features

• This method causes almost no disturbance and uplift of surrounding ground because of air by using low-pressure air.
• As the casing is a pile, the surrounding frictional force largely removes soil from the inside of the casing with air.
• Thus, fore-end bearing layers can be confirmed with the naked eye and the bearing capacity is assured.
• This method greatly improves working efficiency and the casing and hammering can be done at the same time, shortening the period of work time.
• As low-pressure and low-noise machines are used, surrounding conditions are not a consideration.
• Hitting isn’t necessary, so there are no serious problems of noise and few l complaints from residents.
• Consumption of materials is about 5% and there is no hitting, so the head part and piles receive almost no damage. bearing layers.
