耐震用推進管の継手部構造。 Insert the socket of one pipe into the socket of the other pipe so that the tip of the socket contacts the back end of the socket of the other pipe, and place both circumferential surfaces between the inner peripheral surface of the socket and the outer peripheral surface of the socket. A rubber ring is placed in close contact with the surface of the socket, and conductive materials are placed at multiple locations along the circumferential direction of the pipe, placed so as to enclose the rubber ring, and in contact with the inner circumferential surface of the socket and the outer circumferential surface of the socket. An annular groove is formed on the inner circumferential surface, and an annular engagement groove having an appropriate width in the direction of the tube axis is formed on the outer circumferential surface of the insertion port, and a lock ring that can be freely contracted in diameter is inserted into the annular groove on the outer peripheral surface of the insertion port. A joint structure for an earthquake-resistant propulsion pipe, characterized in that set bolts are provided at a plurality of locations in a socket to hug an engagement groove and bias a lock ring in a radial direction to reduce its diameter.
