Abstract

PURPOSE: To perform an operation without any vibration and any noise by a method wherein the hollow pipe of a sand drain device is driven into the poor ground or pulled out by an auger.
CONSTITUTION: When a driving motor 1 is operated, the hollow pipe 3 is rotated through a reduction gear 2, an auger head at the lower end of the hollow pipe 3, and the hollow pipe 3 is driven into the poor ground G. After the hollow pipe 3 is driven, the driving motor 1 is stopped, sand is thrown into an outer casing at the feeding port 8 of the hopper 7. Upon piling of the sand in the hollow pipe 3, a feeding of the sand is terminated and air under a pressurized condition is fed from the air feeding port. Air pushes up the air valve so as to close the stud pipe and then to depress the sand after being forcedly fed in the hollow pipe 3. After a repetitive depression of the sand to feed it into the hollow pipe 3 and compress the same, the hollow pipe 3 is pulled out of the poor ground G. The opening/closing shoe 4 is opened, the sand is filled so as to form a sand column.
