Claims

[Scope of utility model registration request]

In a tube for the propulsion method, which has one tube with an insertion port formed at its tip and the other tube with a socket formed at the rear end that fits into the insertion port of this tube, the tube is inserted into the tip surface of the insertion port. A ring having a cylindrical part to be inserted into the mouth and a flange part protruding at right angles from the outer surface of the intermediate part of the cylindrical part is attached like an ax with one side of the flange part in contact with the other side of the flange part. A plurality of fluid pressure actuation members supported by a support between the outer surface of the cylindrical part are installed at desired intervals in the circumferential direction with their actuation rods facing the direction of the other real socket, The fluid chambers of the actuating member are connected and communicated with each other by a fluid feeding hose, and a desired amount of fluid, which is less than the entire amount, is introduced through the hose, and the pressure is maintained at a predetermined pressure during operation;
Further, a thrust bearing is fixed to the tip of the operating rod, and an enlarged portion is formed on the inner surface of the socket, the opening having an outward vertical stepped portion that abuts against the thrust bearing and receives the transmission of thrust. Pipe joints for pipes used in the propulsion method. □
