PURPOSE:To permit the landing of a bucket to the ground's surface even when a leader is erected at the central part by a method in which an extended member is provided to the top of a leader erected at the central part of a construction machine body and a rope for vertically moving the bucket is hung down from the tip of the extended member. CONSTITUTION:A leader 2 and penetrators 7 and 8 are positioned at near the center of crawlers of a working vehicle 1, and an extended member 5 is provided at the top of the leader 2. A rope 9 is hung down from the tip of the member 5, the lower part of the rope 9 is connected to a receiver, and a bucket 4 for supplying a stabilizer is vertically moved by the rope 9. Sand delivered by the bucket 4 is charged into a hollow casing 7 through a hopper 8 to form a sand pile. Since the bucket 4 is provided in a hanging manner at the tip of the member 5, the bucket 4 can be landed to the ground surface without contacting the working vehicle 1. |
