By returning the generated surplus soil to the pile holes, the amount of surplus soil generated can be reduced by 65% ​​to 70% compared to pre-boring and cast-in-place pile methods. This is an environmentally friendly method that limits the amount of surplus soil. In addition, since no cement is used in any process other than the base reinforcement construction, it can basically be treated as ordinary surplus soil rather than industrial waste. (Conditions must be confirmed)

Since pile installation work can be resumed the next day, each working day can be fully utilized. In response to the recent problem of working hours, we hope to propose a shortened construction period.

By simultaneously burying the piles using the inner excavation method, it is possible to maintain excellent pile center accuracy.

By constructing a maximum 2,400 mm root reinforcement bulb at the tip of the pile, a maximum tip bearing capacity of 17,900 kN can be achieved. (Long-term allowable bearing capacity when the tip average N value is 60)
