Abstract

PURPOSE: To safely conduct a reliable work, by a method wherein a coupling device is employed when a hume pipe is connected to a mahhole.
CONSTITUTION: A hume pipe 1 to be connected makes contact with a spigot 1A' in a wall part of a manhole, and a receiving lever 1 is caused to span the spigot 1A' to couple a left end of a wire 2H to the central part of the receiving lever. A coupler 2 is then installed at the socket part of the hume pipe 1 by means of nip metals 2F. A hook, mounted at the coupler 2, in turn, engages with the right end of the wire 2H through a lever block 2G, and with the lever block 7 operated, the pipe 1 is tightened as the wire 2H is stretched. Through the operations described above, the Hume pipe is pressed gradually against the wall part of the manhole.
