Abstract
PURPOSE: To create a tamping sand pit with a large disc to the soft ground, by pressing a casing in the ground while excavation eliminating earth and sand in the casing, by supplying sand, by tamping sand by means of a tamping device and by pulling up the casing.
CONSTITUTION: Sand in a hopper 22 is supplied to a hopper 6 through a conveyor 19, discharged into a hollow casing 2 by means of a rotary feeder 8 and falling stored in a hopper 11b of a sand tamping device 11 downward disposed. when the sand tamping device 11 is hung up to suitable height by driving a lifting motor 13, sand is discharged downward a bottom of the casing 2. The sand tamping device 11 is let fall up to sand discharged, sand is tamped by means of a top cone 11e and a cone-shaped bottom 11c by driving a vibromotor 11f, and the casing 2 is pulled up by a fixed quantity by means of a pulling-up device 1 doubling as press-in, thus creating one portion of a tamping sand pit in the ground.
