Allow to insert piles in the hard ground of over 50N without losing the advantages of the press-in method thanks to the core drilling mechanism.

   Hard ground press-in method promotes the superiorities of press-in technology while using supportive drilling techniques for piling machine. Based on the core drilling mechanism, this method combines drilling simultaneously with the press-in machine to drive the pile through the ground with a maximum stiffness of more than 50N.

   Drilling, which is only a supporting technique for the press-in method, is implemented to a minimum to minimize the amount of discharged soil and to avoid disturbance of the surrounding soil layer. Therefore, it help complete the pile system with high bearing capacity.
