[

The air spreading between the underground pipe 10 and the reinforcement pipe 20 is cooled by first cooling the space between the underground pipe 10 and the reinforcement pipe 20, 1 connecting portion 11d and the connecting portion 33 of the first supporting mechanism 30 so as to cool the first supporting mechanism 30 and then to move the first supporting mechanism 30 through the opening 34 of the first supporting mechanism 30, (10) to cool the inside of the underground pipe (10). The air spreading between the underground pipe 10 and the reinforcement pipe 20 cools the space between the underground pipe 10 and the reinforcement pipe 20 to a first degree and cools the space between the underground pipe 10 and the reinforcement pipe 20, Passes through the connecting portion 11e of the second supporting mechanism 40 and the connecting portion 43 of the second supporting mechanism 40 so as to cool the second supporting mechanism 40 and then is guided through the opening 44 of the second supporting mechanism 40 10 to cool the inside of the underground pipe 10.

The air discharged from the second nozzle unit 62 of the nozzle mechanism 60 strikes the blade member 53 of the wind spreading mechanism 50 as shown in Fig. 17, And rotates the rotating body 52 of the wind spreading mechanism 50 to rotate the blade body 53. [ At this time, the rotating blade member 53 further diffuses the air, thereby cooling the inside of the underground pipe 10 evenly.

Here, when the rotating body 52 of the wind spreading mechanism 50 rotates, the striking body 54 of the wind spreading mechanism 50 rotates, and the striking film 54b of the striking body 54 is rotated by the ground distribution line L ) While diffusing ambient air. At this time, some vibration is generated in the underground distribution line (L), and dust deposited on the underground distribution line (L) is scattered.

18, the air supplied to the inside of the underground pipe 10 is discharged to the outside (ground) through the air suction pipe 90 as shown in FIG. 18, Dust generated may also be discharged through the air suction pipe 90 to prevent the occurrence of a fire due to dust when a spark occurs in the underground pipe 10.
