等が一般に用いられている。"Conventional technology and its problems" Transport devices for excavated debris used in tunnel excavation work, etc. include those using shear steel cars, those using shuttle cars running on rails, and those using fluids such as muddy water, foam, and air as transportation media. Commonly used methods include those using a conveyor belt, and those using a belt conveyor.

という欠点をそれぞれ有するものである。 However, each of the above-mentioned devices had the following drawbacks, and were not necessarily fully effective. In other words, using a shear steel car requires equipment to replace the shear steel car, and the cycle time becomes long, so the transport efficiency is not very good, whereas using a shuttle car requires long equipment and is not very efficient. In order to ensure good runnability, the linear curvature of the route is limited. Among those that use fluid as the transport medium, if muddy water is used as the transport medium, equipment for solid-liquid separation outside the mine is required. However, the conveyance distance is also controlled by the performance of the slurry pump and is usually 200~
The maximum length is about 250m. When foam is used as the transport medium, the foam disappears during transport and pipes are likely to become clogged. When air is used as the transport medium, long distances can be transported at once. Belt conveyors require extremely high air pressure and air volume, and large-scale relay equipment is required at every predetermined distance. However, belt conveyors have the disadvantage that they are prone to wear and maintenance costs increase.

ａ〜ｃの添字を付してそれぞれを区別している。 The conveying device having the above configuration includes valves 6 and 7 forming the shear storage section 8, an air supply communication pipe 9, and an exhaust communication pipe 1.
By selectively opening and closing the valves 11 and 12 attached to the compressor 4, the compressed air supplied from the compressor 4 is used to intermittently remove excavated slag, that is, to deposit the excavated sludge into a predetermined shear storage section 8. The storage unit 8 is temporarily stopped and stored, and then sequentially transported to the storage unit 8 adjacent to the downstream side of the storage unit 8. The method of use thereof will be explained below with reference to FIG. In addition, in FIG. 2, subscripts a to c are added to the reference numerals of each part to distinguish them from each other.

てしまうようなことはない。 As a result, the air supply pipe 2 is
As shown by the arrow in the figure, the compressed air flows into the supply air communication pipe 9a, flows toward the downstream side within the transport pipe 1, and flows out into the exhaust pipe 3 through the exhaust communication pipe 10b. I will do it. Then, due to the compressed air flowing as described above, the excavated waste Za stored in the storage section 8a is pushed forward and reaches the storage section 8b as shown in (B). Note that, at the same time, the shear Zc stored in the storage section 8c is similarly transported downstream.
Further, when the compressed air passes through the exhaust communication pipe 10b, the filter 13a prevents the passage of shear, so that a part of the excavated shear Za does not flow out into the exhaust pipe 3.
次に、ハに示すように、貯留部８ｂの上流側の

open the upstream valve 6c and close the downstream valve 7c, and also open the valve 11b of the air supply communication pipe 9b connected to the storage section 8b, close the valve 12b of the exhaust air communication pipe 10b, and Close the valve 11c of the air supply communication pipe 9c connected to the section 8c and open the exhaust communication pipe 10.
Let valve 12c of c be opened.

ずりZa′が輸送されてくる。 Thereby, the compressed air flows into the storage section 8b from the air supply communication pipe 9b, flows toward the downstream side in the transport pipe 1, and flows out into the exhaust pipe 3 from the exhaust communication pipe 10c. Therefore, the shear Za is further transported and reaches the storage section 8c as shown in d. In addition,
At the same time, new shear Za' is transported to the storage section 8a from the upstream side.
したがつて、各弁を再びイの状態とし、以後、
以上の手順を繰り返すことによ、ずりを坑口まで
搬送することができる。 Therefore, each valve is returned to state A, and from now on,
By repeating the above steps, the shear can be transported to the mine entrance.

閉塞してしまう恐れも少ない。 As explained above, this conveying device temporarily stops the shear in each storage section 8, but can convey it almost continuously, so it has superior conveyance efficiency compared to the case where conventional shear steel wheels are used. In addition, because only three pipes 1, 2, and 3 need to be laid inside the tunnel, less space is required and equipment costs are reduced compared to using conventional shuttle cars or belt conveyors. Moreover, since it is a simple structure that only opens and closes each valve in synchronization, it does not require much maintenance. Further, a solid-liquid separator is not required as in the case where muddy water is used as the transport medium, and there is less risk of clogging the inside of the pipe as in the case where foam is used as the transport medium.

なつている。 In addition, in this conveying device, the shear is temporarily stopped in the storage section 8 and transported intermittently, so that the air pressure required to convey the shear in this device is limited between the storage sections 8 and 8 adjacent to each other. It is sufficient that it can be transported over a distance of Therefore, as in the case where compressed air is directly sent into the transport pipe 1 from the face for pneumatic transport, or when the shear is vacuum transported by sucking the air inside the transport pipe 1 at the mine entrance, It has become possible to transport shear over long distances without requiring extremely large air pressures and amounts of air, or without requiring large-scale relay equipment at every predetermined distance.
上記の搬送装置の各部の寸法や空気圧、空気量
等は、搬送するずりの性状（特に粘性）や要求さ
れる搬送量に応じて適宜設定すれば良いが、以下
に一例を挙げる。 The dimensions, air pressure, amount of air, etc. of each part of the above-mentioned conveyance device may be appropriately set according to the properties of the shear to be conveyed (particularly viscosity) and the required conveyance amount, and an example is given below.

The mutual spacing between the 8 pieces (L dimension) is approximately 50 to 200 meters. In the case of the above dimensions, the air pressure of the compressed air supplied to the air supply pipe 2 is 3 to 4 kg/cm 2
Assuming that the air volume is approximately 50 to 70 m 3 /min, if the drilling shear has relatively low viscosity, it will be 20 to 30 m 3 /min.
A transportation volume of about m 3 /Hr can be achieved.

If the pump is used as an air source to operate the pinch valve, energy can be used effectively.

Since the structure is such that an air supply communication pipe and an exhaust air communication pipe are provided between them, and valves are provided in each of these air supply and exhaust communication pipes, each valve can be selectively and synchronously opened and closed. This has the effect that the shear can be efficiently conveyed almost continuously while temporarily stopping and temporarily storing the shear in each storage section. According to this conveyance device, excavated debris can be conveyed over long distances without requiring large air pressure or air volume, and without requiring large-scale relay equipment.Furthermore, equipment and maintenance costs are reduced. However, it has an advantageous effect.
