<p>PURPOSE:To provide a connecting device for drawing in a flexible pipe capable of smoothly drawing in the flexible pipe to an excavation hole by a propeller to improve workability and executability in connecting work and further capable of ensuring safety of a worker. CONSTITUTION:In order to propel in the ground while forming an excavation hole by a propeller to make a propelling head 1A lead to an execution pit also in order to connect' the propelling head 1A to a flexible pipe, in a condition that the flexible pipe H is inserted into the execution pit, to draw in the flexible pipe H by the propeller into the excavation hole, a fit connecting part 3 connectably fitted to an end part of the flexible pipe H and a stopped part 5 stoppable to a stop part 4 in a side of the propelling head 1A are individually provided in both end parts. A device is formed to be divided into the first connecting member 6 provided with the stopped part 5 and the second connecting member 7 provided with the fit connecting part 3, and a bendable connecting part 8, which can be changed into the first holding condition attitude holding the second connecting member 7 relating to the first connecting member 6 and into the second holding condition attitude changeable to a bending attitude based on action of external force, is arranged between the first/ second connecting members 6, 7.</p> |
