<p>PROBLEM TO BE SOLVED: To provide an embedded pile having high reliability in pile embedding using a pile rotary press-in machine by performing pile foot protection processing as far as inside a pile tip part.SOLUTION: Provided is a pile embedding method using a pile rotary press-in machine 10, by which foot protection processing of a pile tip part is performed by: detachably connecting a liquid feeding tube L1 having an agitation member R at a lower end part E thereof to a drilling head H of the a first pile P1; pressing in and digging the rotating pile into a ground 100 while extending predetermined numbers of piles and liquid feeding tubes; supplying a foot protecting liquid while gripping and rotating followers P3 and P4 connected to a last pile P2. Next, foot protection processing inside the pile tip part is also performed by: stopping the pile rotation by gripping the lower follower P3 by using an auxiliary gripping mechanism 50; supplying the foot protection liquid while rotating the upper follower P4 in this state to cause the liquid feeding tubes L4 to L1 and the agitation member R at the lower end part E of the liquid feeding tube, which are connected to the upper follower P4, to rotate.</p> |
