Abstract
PURPOSE: To easily detect a sand surface, by inserting a non-rotation hollow internal tube into a hollow external tube rotated by a driving machine.
CONSTITUTION: After a hollow external tube 1 is inserted into the soft ground as it rotates, sand 18 is charged in a hollow tube 7 from a hopper 10. When a voltage applied to a torque motor 14 is lowered, a weight 15 falls down due to its own weight, and stops falling down after reacing a sand surface 18'. At this time a wire rope 16 is not loosed due to a tension, which is given by the torque motor 14, working on the wire rope 16. As a result of the sand surface 18' lowering, a torque produced by gravity of the weight 15 is applied to a drum 12, and consequently the wire rope 16 is wound down, which results in lowering of the weight 15 following the movement of the sand surface 18'. The sand surface can thus be easily detected because the sand surface at the inside of a non-rotation hollow tube 9 can be detected in such a manner as mentioned above.
