PROBLEM TO BE SOLVED: To provide a slurry pressuring type small-diameter pipe driving equipment which can be applied to a small diameter starting vertical shaft and is effective also for a water-bearing sand layer. ;SOLUTION: A slurry pressuring type small-diameter pipe driving equipment 1 performs two-process type driving, permits the connection of a slurry-conveyance pipe 3 and a slurry drain pipe mutually in axial direction in a detachable manner, and constitutes a connecting body 1. And a rotating driving force from an initial pushing apparatus is transmitted to a cutter portion 300 of the main body 13 of a driving machine through a central rotating shaft 2, the central rotation shaft 2 is mutually connected in the axial direction thereby constituting a connected body 1, the driving force from the initial pushing apparatus is transmitted to the main body 13 of the driving machine through the driving force transmitting shafts 5 to (7), the driving force transmitting shafts 5 to (7) are mutually connected in the axial direction thereby constituting the connected body 1, and both the end portions of the central rotating shaft 2, slurry-conveyance pipe 3, slurry drain pipe and the driving force transmitting shafts 5 to (7) are coupled to the forward connecting members and backward connecting members.;COPYRIGHT: (C)1999,JPO
