DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an underground temporary storage device for deformed segments used to correct the direction of tunnel excavation while excavating a long-distance tunnel using a shield excavator and a method of using the same.

[0002]

2. Description of the Related Art A rear bogie such as an operator unit, a pump unit, and a power unit is connected to the rear of a shield excavator. The shield excavator excavates the ground in front of the excavator while pulling these subsequent bogies. The segment to be incorporated into the excavated tunnel wall is transported from the rear of the excavated tunnel by a segment carrier to immediately after the shield excavator, and assembled by an erector. Normally, a segment 1 having a rectangular inner surface as shown in FIG. 2 is used for such an operation.

[0003] When an extremely long tunnel such as an undersea tunnel is excavated straight by a shield method, the tunnel may bend. In such a case, in order to correct the tendency to bend and proceed straight ahead, a deformed segment 2 having different lengths of sides facing the inner surface shape as shown in FIG. 3 may be incorporated into the tunnel wall.

[0004]

Conventionally, when it becomes necessary to incorporate the deformed segment 2, the deformed segment 2 is loaded on the segment carrier from the back of the tunnel being excavated each time, and immediately after the shield machine. Had been transported to

However, from behind the tunnel during the excavation,
Since a large number of ordinary segments 1 are always conveyed, it is difficult to carry the deformed segment 2 from the rear when the deformed segment 2 is required, and it cannot be assembled immediately, resulting in poor work efficiency.

[0006] The present invention ameliorates these conventional disadvantages,
It is an object of the present invention to provide an underground temporary storage device for deformed segments and a method of using the deformed segments so that the deformed segments can be sent immediately after the shield machine when the deformed segments are required.

[0007]

SUMMARY OF THE INVENTION The present invention provides a shield machine, a deformed segment loading portion provided behind the shield machine, and a deformed segment loading portion from behind a tunnel dug by the shield machine. A segment transport vehicle that transports a segment through the side to immediately after the shield machine, and a reshaped segment between the segment transport vehicle positioned on the side of the deformed segment loading portion and the deformed segment loading portion; Loading a deformed segment onto a segment carrier truck from behind a tunnel being excavated by a temporary underground storage device for a deformed segment, and a shield excavator provided with a deformed segment loading section at the rear, characterized by comprising: And transport the deformed segment to the side of the deformed segment loading section,
The deformed segments loaded on the segment transport trolley are transferred to the deformed segment loading section by a transfer device and waited, and when it became necessary to incorporate the deformed segment into the tunnel wall, the segment transport trolley was moved to the deformed segment loading section. A deformed segment which is disposed laterally, reloads a deformed segment on the deformed segment loading portion on the segment transport trolley by the transfer device, and advances the segment transport trolley to immediately after the shield excavator. How to use the temporary underground storage device,
It is related to.

[0008]

The deformed segments are loaded on the deformed segment loading portion provided behind the shield machine in advance, and when the deformed segments are needed, the deformed segments on the deformed segment loading portion are transferred to the transfer device. When the segment carrier is re-loaded on the segment carrier and the segment carrier is advanced to just after the shield excavator, the deformed segment can be immediately incorporated into the tunnel wall.

The shield tunneling machine 3 excavates the front ground while pulling the trailing truck 4 by the connecting device 5. And around the dug tunnel,
The segment 1 is assembled by an unillustrated erector to construct a tunnel wall. The segment 1 used for assembling is loaded on the segment carrier 6 from the ground (right side in FIG. 1) behind the tunnel excavated by the shield excavator 3, travels on the rails 7, and Immediately after, it is supplied to an unillustrated erector. Immediately after the shield machine 3, the segment transport trolley 6, which has been emptied by supplying the segment 1 to the erector, moves to the rail 8 and is sent to the rear of the tunnel.

Behind the shield machine 3, a deformed segment stacking section 9 is provided. In the embodiment shown in FIG. 1, a truck connected to the rear of the succeeding bogie 4 is used as the deformed segment loading section 9;
May be formed integrally with the shield machine 3 in front of the trailing bogie 4, or may be configured so that a part of the trailing bogie 4 is also used. A rail 10 is laid in parallel with the rail 7 on the outside of the rail 7 where the deformed segment loading section 9 is provided, and transships over the rail 10 from above the deformed segment loading section 9. Apparatus 1
1 is provided.

FIGS. 4 to 6 show an embodiment of the transfer apparatus 11, all of which are front views as seen from AA in FIG.

The embodiment shown in FIG.
A delivery table 12 ′ is provided on the
On the 2 ′, there is a pallet truck 12 that can move across the segment carrier truck 6 and the variant segment loading unit 9 stopped on the rail 7 on the side of the variant segment loading unit 9,
With the pallet truck 12, the deformed segments 2 can be reloaded between the segment transporting truck 6 and the deformed segment loading section 9.

FIG. 5 shows an embodiment of a hoist 1 with a traversing device.
The hoist 13 with the traversing device is provided with the segment carrier 4 stopped on the rail 7 on the side of the deformed segment loading section 9 and the deformed segment loading section 9.
