Document Type and Number:
Japanese Patent JP2573784
Kind Code:
B2
Abstract:
PURPOSE: To obtain a ground improving device, in which a machine frame loaded with an exciter connected to an underground intruding rod is elevatably supported by a leader through a suspension wire and which has the excellent stability of the leader during the drive of the exciter and in which abrasion of an elevating guide of the leader is hard to be generated and the labor and the cost for repairing is remarkably reduced in comparison with the conventional one.
CONSTITUTION: A ground improving device is provided with a cushioning frame 10 interposed between a machine frame 5 and a leader 2, and the machine frame 5 is furnished with a vertically sliding guide frame 11 and a bracket 12 projected to the leader 2 side. The leader 2 is equipped with a vertical elevation guide part 3, and the cushioning frame 10 has a machine frame side fitting part 13 and a leader side fitting part 14, which are fitted to the sliding guide frame 11 and the elevation guide frame 3 freely to slide vertically, and a vertical fitting rod 16. The bracked 12 of the machine frame 5 is loosely fitted to this fitting rod 16 at a part between a pair of upper and lower compression coil springs 15a, 15b.
