Abstract

PURPOSE: To make easy the layer inspection work by smoothly forwarding the layer inspection electrode, through the connection of layer inspection cable to the layer inspection electrode in the protective cylinder from the cable inlet.
CONSTITUTION: The layer inspection cable 3 is connected to the layer inspection electrode 6 in the protective cylinder 5 through the cable inlet 4. Further, the connection tube 2 and the protective cylinder 5 are loaded, further the layer inspection cable 3 is located outside the digging tube 1 and the connection tube 2 is mounted on the digging tube 1. While keeping the connection, the protective cylinder 5 is inserted in the test drill hole 7. On ground, the digging tube 1 is jointed and a series of protective cylinder 5, connection tube 2 and digging tube 1 are fed to the test drill hole while operation at the digging machine. If the connection tube 2 is not used, layer inspection is made by connecting the layer inspection electrode 6 through the cable inlet at the protective cylinder 5 and inserting the test drill hole 7.
