Description of the Related Art When a worker temporarily takes a break in a tunnel mine under construction, he or she moves inside the tunnel to a resting place outside the mine, or selects an appropriate place in the mine to take a break. Or, if there is a temporary rest area or break room in the mine, take a break there.

歩に頼らざるを得ず、現場と坑外との往復に時間がかか
り工期の遅れにつながるため、現実的には就労時間内で
坑外休憩を取ることは難しい。Of the above-mentioned resting methods, outside tunnels are the most ideal because the dust concentration inside the tunnel is high and the air environment is poor. However, if the tunnel excavation has progressed to some extent and the work vehicle does not make frequent round trips, it has to rely on walking to move outside the mine, and it takes time to make a round trip between the site and the mine. In practice, it is difficult to take a break outside of the mine during working hours because it will delay the construction period.
【0004】これに対し、一般にトンネル内は前記のご

とどまらざるを得なかった。[0005] Incidentally, the conventional resting place or resting room is actually just a name, and in fact, it is a building in which a sitting room is prepared in a small room separated by a simple partition in a pit. Even in the rest area, the same atmosphere as the mine was exposed, and even if this place was used as a rest area, it had to stay there with the dust mask in the same manner as described above.

提供するものである。SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and its object is to completely shut off the inside from the outside world, to maintain a clean atmosphere, to take a break by removing a dust mask, and to provide sufficient comfort. This is to provide a mine resting area where the property can be obtained.

1)。In order to achieve the above-mentioned object, the present invention provides a method for controlling the position of a tunnel inside a tunnel through a branch pipe connected to an outside air introduction pipe extending from the outside of the tunnel to the tip of the tunnel. The outside air is blown into a building temporarily installed in an airtight state (claim 1).

成とすることができる(請求項3)。[0008] In the present invention, the outside air is introduced from the outside air introduction pipe, and the outside air is blown out at the entrance and exit of the building so as to isolate the air inside and outside the building to form an air curtain (Claim 2). A configuration in which an air gun type air gun for local dust removal is provided at an end of a pipe branched from the pipe (claim 3).

着した粉塵を払い落すことが出来る。Therefore, in the present invention, the inside of the building is always in the same air atmosphere as the outside air, and even when entering or exiting the building, the building is air-blocked from the outside by the air curtain.
When the worker enters the building, the dust attached to the clothes can be removed by operating the hand nozzle of the air gun to eject air to his / her body.

している。DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below in detail with reference to the accompanying drawings. Figure 1
2 shows a tunnel construction site provided with a rest area according to the present invention. In the figure, a trunk air pipe 2 for introducing outside air from the outside of the tunnel to the tip of the tunnel (face 1a) is piped to the side wall inside the tunnel 1 formed by excavation toward the face 1a, not shown. Clean external air is constantly flowing in the direction of the white arrow in the figure by an air pump or the like.
【0011】トンネル坑1内の適宜位置であって、幹線

Therefore, clean outside air is always supplied to the rest area 3. It is needless to say that the air outlet 10 is provided with a flow rate adjusting damper (not shown), an air flow direction adjusting louver, and the like. In addition, separately, at rest area 3,
Exhaust means for exhausting the air inside the tunnel to the inside or outside of the tunnel may be provided.

Have been. Therefore, when the door 5 is opened and the doorway is opened, the air curtain blows out from the outlet 11 to shut off the inside and outside of the rest area 3 in an air manner so that the inside can be kept clean every time the door 5 is opened and closed. I have to. In addition,
The air curtain may be blown out constantly, but the air curtain may be blown out only when the door 5 is opened. Further, an air curtain in which air flows laterally from the side of the door 5 toward the other side may be used.

している。The lower end of the third branch pipe 9 is connected to a horizontal pipe 12 arranged outside the building, and communicates with a plurality of air guns 14 hanging below the horizontal pipe 12. Each air gun 1
Reference numeral 4 denotes an air nozzle 14b of a trigger valve type connected to a distal end of a flexible hose 14a hanging down on a horizontal pipe. The worker A has the air nozzle 14b, and when the trigger valve is operated, pressurized air is blown out. The dust adhering to the clothes of A can be removed by blowing it off, and by entering the rest area 3 after the dust removal work, the cleanliness in the rest area can be kept higher. .
【0018】なお、休憩所3の建物大きさに余裕がある
