However, since the suction hose is used as a pressure-resistant hose, as is well known, if it is formed in a loop, it is bulky and takes up space, which hinders the passage of the steel bogie described above. In addition, it is necessary to periodically inspect the surface of the suction hose in places where it frequently comes into contact with the steel bogie, and pay attention to any damage. When a vinyl resin air tube with a ring is used, there is a problem that the air tube flaps during blowing, noise due to wind noise is generated, and a pressure loss occurs due to a slack portion, so that ventilation efficiency is significantly reduced.

[0010] Of these, the tip reducer 11 uses the suction hose 1 to determine the diameter of the innermost cylinder 21A of the multiple cylinder 20.
When connecting with the innermost cylinder 21A of the multiple cylinder 20, the distal end 15a of the joint wind pipe 15 is fixed together. That is,
The distal end 15a of the joint wind tube 15 is folded outward at a distal end position of the innermost cylinder 21A of the multiple cylindrical body 20 by taking a predetermined amount of fold 17 so as to cover the fold 17 with the rear end 11b of the distal reducer 11. And is fixed by a plurality of setscrews 16. The connection between the distal end reducer 11 and the suction hose 1 can be made using a known pipe connector 3 (see FIG. 2) such as a Victoria joint.

The multiplex cylinder 20 has a multiplex structure in which a plurality of cylinders 21 whose diameters gradually decrease stepwise are accommodated in an outermost cylinder 21B in a multistage telescopic shape. In the present embodiment, the multiple cylindrical body 20 includes twelve cylindrical bodies 21. The length of one cylinder 21 is 80 cm, and locking flanges 22 are formed at both ends of each cylinder 21 as shown in FIG. The locking flange 22 functions so that the tubular body 21, which is overlapped and accommodated, slides and the whole body is pulled out, so that the tubular body 21 can be maintained in the extended state without being pulled out. In the present embodiment, a galvanized steel plate is used for the cylinder 21. However, it is also possible to reduce the overall weight by using a synthetic resin tube or the like.

The joint air tube 15 housed inside the multiple cylindrical body 20 may have a structure equivalent to a known bellows-type vinyl resin air tube with a ring. The full length is the most expanded state when all the cylinders 21 are pulled out at the longest, and is the most contracted state when all the cylinders 21 are overlapped and accommodated at the shortest. Joint wind pipe 15
The reinforcing ring sewn or adhered to the base cloth may have a plurality of ring-shaped steel wires continuously arranged at a predetermined interval, as in a known product, or one reinforcing ring. The spiral steel wire may be arranged in the extension direction of the joint wind pipe 15.

FIG. 2 is a front view showing the air duct guide 10 arranged in the tunnel. A guide sled 30 (warp) is attached to the tip reducer 11 shown in FIG. When the multiple cylinder 20 is extended, the innermost cylinder 21A
, The entire multiple cylinder 20 is extended by sliding so that the cylinder 21 is sequentially pulled out. When the nested cylindrical body 21 slides and extends, the tip reducer 1 having a small pipe diameter is formed.
It is expected that one part tends to hang under its own weight. In such a case, the end reducer 11 and the joint 3 with the suction hose 1 may be hooked on the sleeper 5 (see FIG. 2B) laid at a predetermined interval. Therefore, the guide thread 30 is attached to the lower surface of the distal end reducer 11 so that the distal end portion of the air duct guide 10 can move forward on the sleeper 5 smoothly. It is needless to say that a guide thread of this type is not necessary when a portion where a scaffold plate, floor material, etc. are spread is extended.
