Abstract

PROBLEM TO BE SOLVED: To provide a method for carrying in segments, allowing the segments to be carried into the shield machine side through a narrow space part at the side of a gas pipe in laying the gas pipe in a tunnel abreast with boring the tunnel, and allowing segment lining along with boring of the shield machine even during work of welding the gas pipes to each other. SOLUTION: A conveying truck with several segments loaded in a vertically placed state travels on a rail parallel with the gas pipe laid in the tunnel, to convey the segments to a segment storage place behind the shield machine, and the segments on the conveying truck are transferred onto a set-off truck behind the segment storage place. The segments on the set-off truck are then lifted by a lifting device travelable in the longitudinal direction, and loaded in the segment storage place. Since the conveying truck cannot travel during work of welding the gas pipes to each other, the segments stocked in the segment storage place are fed to the shield machine side and assembled along with boring the tunnel.

2. Description of the Related Art Conventionally, when laying a gas pipe in an underground tunnel, after excavating the tunnel with a shield excavator, a gas pipe of a fixed length is sequentially carried into the tunnel.
A long gas pipe is formed by repeatedly performing a work of welding a gas pipe to be laid next to a previously laid gas pipe in a butt state and welding between the butt open end faces. Therefore, the outer diameter of the shield excavator is determined by the space required for carrying in and welding gas pipes, but when performing shield excavation work and gas pipe laying work simultaneously in a narrow excavated tunnel, Materials such as segments cannot be carried into the shield excavator side, and the work of carrying in the materials is difficult due to the presence of laid gas pipes.

Therefore, it is impossible to lay the gas pipe behind the shield excavator while excavating the tunnel with the shield excavator. Excavation of a tunnel over the entire length of the construction design line is carried out, and after that, gas pipes are carried into the tunnel and connected sequentially, and the construction period is long and the construction cost is high. There is a problem that becomes. Particularly, in recent years, long-distance construction has been performed, and laying of gas pipes after excavation of a long tunnel requires a remarkable construction period.

On the other hand, if the segment can be carried into the shield excavator through the narrow space in the tunnel despite the gas pipes being laid, the tunnel is excavated in parallel with the excavation of the tunnel by the shield excavator. Gas pipes can be laid, but during the welding work of the gas pipes, the carrying passage is blocked by welding equipment, so it is not possible to carry in the segments to the shield excavator side. There is a problem that the entire construction period is greatly delayed due to the necessity of interruption.

In this way, the segment transferred onto the take-over truck is carried by the traveling of the take-over truck to the rear end of the segment storage place provided in the tunnel at the rear of the shield excavator. By rotating, a posture that can be easily assembled by the erector of the shield excavator, that is, the curved inner surface is turned horizontally so as to face upward, and then sequentially moved to the segment storage location by the traveling suspension device, It is carried in. At this time, when the rotation receiving frame of the take-over trolley is rotated in a horizontal state, a plurality of segments are stacked vertically, so that the lifting and transporting by the traveling suspension device can be easily performed and the segment storage location can be easily obtained. Can be stacked in the stacking mode. In addition, since the lifting column having the horizontal arm at the upper end is erected on the rear end side of the bogie, the segment can be lifted and transported smoothly without disturbing the operation of the traveling suspension device. it can.

The transport of segments to the segment take-over truck is not performed by reciprocating one carrier, but by connecting a plurality of carriers in series and transferring a plurality of segments to each carrier. Arranged in a vertical position, placed and transported, one segment stealing trolley is moved to the position of each transport trolley and laid sideways, the segments on the transport trolley are received as described above, and the side of the suspension device side After rotating the rotation receiving frame in a horizontal state, the process of reloading to the segment storage location by the suspension device is repeated, and the plurality of segments on each segment transport trolley are sequentially transferred to the segment storage location. This is a state in which the layers are stacked at small intervals.

In this case, if a rotation receiving frame is provided on the segment transport vehicle, the segment take-over truck is not required. However, as described above, a plurality of segment transport vehicles are connected and a large number of segments are connected. Since it is a thing to convey, providing a rotation receiving frame on all segment conveyance vehicles not only complicates the structure and increases the cost, but also travels in a narrow tunnel in parallel with the laid gas pipe. At this time, the rotation receiving frame may hinder its traveling, so it is placed vertically on a plurality of segment transport vehicles up to the inside of the tunnel behind the shield excavator where the gas pipe has not yet been laid. To load multiple segments
At that position, it is sequentially transferred to the rotation receiving frame of one segment take-over truck. Therefore, the transport trolley may have a simple structure in which a frame member capable of storing and holding the segments is provided upright on the front and rear ends of the trolley body narrower than the segment width. However, the segment can be transported.

Further, when the shield excavator excavates a fixed length and welds the rear end of the gas pipe of a fixed length to the front end of the gas pipe laid first, it is laid in parallel with the laid gas pipe during the welding operation. Although the segment transport trolley cannot pass on the rail that is doing, before the welding work of the gas pipes, as described above, a plurality of segments are carried into the shield excavator side by a plurality of transport trolleys and Since it can be stocked in the segment storage place by the suspension device, by supplying a large number of the stocked segments to the erector side provided in the rear end of the shield excavator during welding work of the gas pipe, The excavation of the shield excavator, the assembling of segments, and the lining process can be performed efficiently without interruption, and the entire construction period can be significantly reduced.
