摘要： PURPOSE:To obtain a self-propelled duct continuity testing device in which a bobbin can be passed inside a duct by one operator by a method wherein a self-propelled front tractor and a self-propelled rear tractor whose cross-sectional diameter is a little smaller than the cross-sectional diameter at the inner circumference of the duct are installed at the front and the rear of the bobbin and the respective tractors are operated by an operating machine. CONSTITUTION:Driving gears for a front tractor 3 and a rear tractor 4 are driven by the operation of an operating machine in a radio manner or via a wire 5; Thereby, wheels 8 are turned, and the front tractor 3 and the rear tractor 4 are run inside a duct 7. Thereby, a bobbin 1 which is coupled via joint mallets 2 in the middle of both tractors 3, 4 is run inside the duct 7. When the bobbin 1 or the like reaches one end of the duct 7 or when an obstacle exists inside the duct 7, the wheels 8 are turned reversely so as to be run backward. Thereby, the bobbin 1 is set to continuity inside the duct 7, and it is confirmed whether the inside of the duct 7 is deformed or an obstacle exists inside the duct. Thereby, the bobbin 1 can be passed through the inside of the duct 7 by one operator.

摘要： PROBLEM TO BE SOLVED: To reduce the weight of a segment, and to easily and quickly connect segments to each other by forming a standing edge of each divided simplified segment so as to abut on each other in a tunnel, and inserting pins into corresponding holes for locking. SOLUTION: Multiple divided simplified segments are connected to each other in the inner peripheral wall of a tunnel 5 so as to form the tunnel 5. The simplified segment 4 has a standing edge 4a in each side of a curved steel plate, and each standing edge 4a has plural holes 4b and air bleeding holes 4c. Two standing edges of the simplified segments 4, which are connected to each other, are locked with the abutment hole 4a for connection through a fastening tool 6 or 7. A partitioning wall plate 8 is suspended from the ceiling of the tunnel 5 in the longitudinal direction, and a filling pipe 13 is inserted into the partitioning wall plate 8. Multiple pipelines 14 are arranged inside of the tunnel 5, and the filling agent is filled from each filling pipe 15 except for an upper clearance part of the tunnel. Continuously, the upper clearance part is filled with the filling agent, and while the filling pipe 13 is drawn out so as to easily fill the ceiling part of the tunnel with the filling material.

摘要： PROBLEM TO BE SOLVED: To positively crush an existing conduit even if it is a long or curved one, by following the conduit, and to replace the existing conduit by a new one. SOLUTION: In implementation of replacement, a propeller 4 arranged in a starting shaft 1 has the plurality of new pipes 7 connected thereto in a manner being foldable with respect to each other, and a large-diameter cutting bit 9 is rotatively mounted on the tip of the new pipes 7. Then a plurality of clevis augers 10 connected to the propeller 4 are foldably connected to the interior of the new pipes 7, and an inner cutting bit 11 arranged on the periphery of the tip of the clevis augers 10 and the large-diameter cutting bit 9 are rotated together in one body, followed by attaching one end of a towing wire 12 penetrated from an arrival shaft 2 into the existing Hume pipe 3, to the tip of the clevis augers 10, to thereby tow the clevis augers 10 by the towing wire 12. Further while the tip of the clevis augers 10 is pinched by an opening at one end of the existing Hume pipe 3, the inner cutting bit 11 etc. are rotated to crush the existing Hume pipe 3, and thus the new pipes 7 are laid in the ground.
