Title:
EARTHQUAKE PROOF PIPE PROPULSION LAYING CONSTRUCTION METHOD AND PROPULSIVE FORCE TRANSMISSION DEVICE
Document Type and Number:
Japanese Patent JP2019138449
Kind Code:
A
Abstract:
To provide an earthquake proof pipe propulsion laying construction method capable of reducing the operation time required for the pipe contact while a propulsion transmission device can be attached to the socket of a trailing pipe on the ground, moreover, even after the propulsive force transmission device is mounted, the check state of the rubber ring fitted into the rubber ring groove of the receiving port can be confirmed with a check gauge, and the propulsive force transmission device.SOLUTION: A propulsive force transmission device is composed of a plurality of clamp members 12 and a ring member 14 connected to the clamp member 12 with a bolt 13, the clamp member 12 having an inclined plane inclining in an axial direction of a trailing pipe 5, the ring member 14 is fitted into the inclined plane, the clamp member 12 is fixed to a socket 3 by tightening the bolt 13 and moving the ring member 14 along the inclined plane; between the inner surface of the clamp member 12 and the outer surface of the socket 3, a clamp side gap 19 is formed; and between the inner surface of the ring member 14 and the outer surface of the socket 3, a ring member side gap 22 is formed.SELECTED DRAWING: Figure 1
