Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an underground transportation vehicle and an underground transportation method, and more particularly to an underground transportation vehicle and an underground transportation method for connecting pipes such as gas pipes and water pipes inside a tunnel at the same time as shield digging. .

[0002]

BACKGROUND ART Generally, in a shield method, a tunnel excavator is provided with a material necessary for shield excavation, such as rails, sleepers, and shield segments, from the vertical shaft in a tunnel formed by excavating with a shield excavator. It is designed to be transported and supplied to the side by an underground trolley.

When a pipe such as a gas pipe or a water pipe is laid in a tunnel formed by excavating by a shield excavator, during the shield excavation, as described above, along with the excavation, rails, sleepers, and further The materials required for shield excavation such as shield segments must be transported from the vertical shaft side to the shield excavator side, and if piping is laid during the shield excavation, the pipes will interfere and the underground transportation cart cannot pass, and the rail It is difficult to transport materials such as sleepers, sleepers, shield segments, etc. necessary for excavation, or pipes that are sequentially connected.

Particularly, when the difference between the tunnel diameter and the pipe diameter becomes small, it becomes more difficult to carry the material required for further excavation and the subsequent pipe.

Therefore, in such a case, the pipe is not laid during the shield excavation, and the pipe laying work is started only after the excavation by the shield excavator is completed.

Further, since it is necessary to dismantle the shield machine and carry it to the ground after completion of the shield machine work, the pipe laying work has been performed after the disassembly of the shield machine is completed.

[0007]

As described above, in the case of laying a pipe in a tunnel pit, if the shield excavation work and the pipe laying work are carried out simultaneously, the materials and pipes necessary for the shield excavation cannot be conveyed. Therefore, the pipe laying work is not performed during the shield digging work, and the pipe laying work is started after the shield digging work is completed, so that the time required for the shield digging and the time required for the pipe laying are added independently. There is a problem that the time becomes the construction time, the construction period is significantly extended, and the cost is significantly increased.

Further, after the shield excavation work is completed, the shield excavator is dismantled and carried to the ground. Therefore, when the shield excavator is disassembled, the pipe laying work is performed.
There was a problem that the construction period would be further extended by the time required to dismantle the shield machine.

The present invention has been made in view of such conventional problems, and an object thereof is to convey materials and pipes necessary for shield excavation even when pipes are laid inside a tunnel pit, and to shield the pipes. It is an object of the present invention to provide an underground transportation vehicle and an underground transportation method that enable simultaneous progress of excavation and laying of pipes to shorten a construction period and reduce costs.

Next, the underground transportation method of the present invention will be described focusing on the case where the underground transportation vehicle according to the second embodiment is used for transportation.

First, inside the tunnel 12, a shield excavator (not shown) cuts the face of the face of the tunnel 12 at the tip of the tunnel 12. As the shield excavator excavates the shield segment, the shield segment is excavated. It is designed to be assembled and connected to the back of the machine for excavation.
Behind this shield machine, a back trolley 62, a pump trolley 64, a power source trolley 66, a segment piece temporary placement trolley 6
Rear carriages such as 8 are connected. Then, from the starting shaft (not shown) side, the materials necessary for the excavation of rails, sleepers, segment pieces, etc. are fed by the underground trolley carrier 10, and at the same time the starting shaft is shielded, gas pipes, water pipes, etc. The connection work of the piping of the
When 0, the pipes are sequentially supplied to the tip side to be connected.

In this case, during the pipe connection work, the material required for shield excavation such as the segment piece cannot be supplied. Carrier 10
Supplied by. For example, when transporting and supplying the segment piece 54, the segment piece 54 is transported to the position of the segment piece temporary placement carriage 68 using the underground transport carriage 10 while the segment piece 54 is placed on the pallet 56, and the segment piece temporary placement carriage 68 is placed on the pallet 56. The segment pieces 54 are temporarily placed together. In this case, because of the existence of the passage space 34 formed in the lower portion of the bogie main body 16, the underground transportation vehicle 10 can easily move to the segment piece temporary storage vehicle 68 through the existing pipe 32, and also the underground transportation vehicle. Since 10 is slightly longer than the length of the transport pipe 24, a large amount of segment pieces 54 can be transported at one time and temporarily placed on the segment piece temporary placement carriage 68.

Next, the transport and supply state of the transport pipe 24 will be described. First, in the start shaft, as shown in FIG. The gate type carriage main body 16 is moved along the rail 14 so as to straddle the arranged transport pipe 24. Then, the trolley body 16 is positioned above the transport pipe 24 and raises the temporary receiving stand 44 to hold the transport pipe in a floating state. In this state, the support member 18 provided on the carriage body 16
The electric pipe 38 causes the transfer pipe 24
The lower limit position of the motor and the gears 40 and 42 at the lower limit position of the lower end of the support, and the motor and gears 40 and 42 are rotated from the drooping state to the facing substantially horizontal position. As shown in FIG.
The lower part of the transport pipe 24 is gripped by 8. As long as the support member 18 supports the transport pipe 24 by sliding as shown in the fourth embodiment, the transport pipe 24 can be supported without the rotation space of the support member. Even if the difference between the diameter and the diameter of the transport pipe 24 is small, the transport can be sufficiently performed. Then, after supporting the transport pipe 24 by the support member 18, the support member 18 is raised by the electric cylinder 38, and the transport pipe 24 is moved to the transport pipe support space 36 in the upper inner space of the carriage body 16 through the state of FIG.
Then, as shown in FIG. 12, the support state in the transfer pipe 24 is maintained.

Next, while the carrier pipe 24 is held in the support space 36 by the support member 18, the carriage main body 16 is moved along the rail 14 into the tunnel 12 and formed in the lower inner space of the carriage main body 16. The passing space 34 passes through the existing pipe 32 installed in the lower part of the tunnel 12 to move the carriage body 16 to the end position of the existing pipe 32. In this case, due to the existence of the passage space 34, the existing pipe 3
The transport pipe 24 can be freely moved on the upper part 2. Further, when the underground transportation vehicle 10 moves inside the tunnel 12 and approaches a curved portion of the tunnel 12, the two cart bodies 16 that are bendably connected are bent along the curve, and the truck body 16 is It is possible to pass through the curved portion without hitting the tunnel wall of the tunnel 12. In this case, the two wheels 18 located in the center of the carriage body 16
By rotating along the curve of the rail 14, the track of the rail 14 can be easily followed. Further, when the underground transportation vehicle 10 passes through the curved portion of the tunnel 12, the transportation pipe 24 supported by the vehicle body 16 laterally moves, but this lateral movement is absorbed by the support member 18. ing. In this case, by using the underground transportation vehicle 10 as shown in the third embodiment, it is possible to easily deal with the tunnel 12 having the sharp curve portion.

Then, at the end position of the existing pipe 32, as shown in FIG.
As shown in FIG.
Is lowered to the lower limit position, and the temporary support 44 temporarily placed at the bottom of the tunnel is raised, and then the motor and gears 40, 42 are used to bring the support member 18 into opposition to the substantially horizontal position as shown in FIG. When rotating from the state to the hanging state,
The holding state of the transport pipe 24 by the support member 18 is released, and the transport pipe 24 is imaged on the temporary receiving stand 44. In this state, the delivery of the transport pipe 24 is completed, and the temporary receiving stand 44 is lowered. It is possible to connect the transfer pipe 24 to the existing pipe 32. When connecting the transport pipe 24, the transport pipe and the existing pipe 32 may be appropriately jacked up and positioned, and then connected using an automatic welding machine or the like, and jacked down to perform the main fixing.

After the connection of the transfer pipe 24 is completed, as described above, the underground transfer carriage 10 is returned to the starting shaft, the material necessary for the shield excavation is transferred from the starting shaft to the shield machine side, and then the next transfer is performed. By repeating the work of feeding and connecting the pipe 24 from the starting shaft to the end position of the existing pipe, the pipe connecting work can be performed at the same time as the shield excavation work, and the construction period can be significantly shortened.

Further, when the excavation work by the shield machine is completed, the pipe connecting work is proceeding immediately before the rear bogie as shown in FIG. 8, and thereafter, simultaneously with the dismantling of the shield excavator and the rear bogies. If the pipe connecting work is continued, the pipe connecting work can be completed almost at the same time as the dismantling is completed.

The present invention is not limited to the above-mentioned embodiments, but can be modified in various forms within the scope of the gist of the invention.

For example, in each of the above embodiments, 1
Although description has been made of the one including the trolley body and the one including the two trolley bodies connected, the present invention is not limited to this example, and three or more trolley bodies can be connected.

In each of the above-described embodiments, the case where the passing space and the supporting space are formed in the vertical direction of the bogie main body has been described, but the present invention is not limited to this example, and depending on the construction conditions, the passing space may be changed in the lateral direction. It is also possible to form a support space.
