Abstract

PURPOSE: To prevent the twist of a draining material by a method in which a casing is enclosed without cutting the draining material by means of an air pipe control valve and then the draining material is placed with a looseness enough not to cause the staying of the draining material at the lower end of the casing.
CONSTITUTION: The casing 7 of a placing assembly consisting of a vibrohammer 4, a draining material feeder 5, an air pipe control valve 6, and the casing 7 is brought down by a ratchet wheel mechanism rotating along a guide wire 3, and its tip is placed on the ground. The draining material 9 is pulled by a tip packing 10, pierces through the air pipe control valve 6 from the feeder 5, and extends to the lower end of the casing 7. Then, the vibrohammer 4 is operated to drive the casing 7, where the drain material 9 penetrates into the ground while increasing its looseness since a feeding roller 5 and the ratchet wheel turn with a fixed interlocking ratio. After the completion of the driving, the upper part of the casing is sealed up by the air pipe control valve 6, air is charged under pressure, and then the casing 7 is withdrawn by leaving the drain material 9 under the ground.
