Description

  The present invention relates to a method and apparatus for conveying an article (heavy article) in a tunnel, and in particular, a method for conveying an article in a tunnel that can stably convey the article (heavy article) even when the tunnel has a steep slope. And a transfer device.

  As a method of collecting the excavator after the shield machine has reached a predetermined reach, conventionally, the excavator is divided into several blocks and units by gas cutting or the like in the mine, and these blocks are In order to use it for the following equipment, there are known ones that are transported to the tunnel wellhead side and collected using sleepers and rails laid in the axial direction at the bottom of the tunnel.

  However, the sleepers and rails are designed and laid according to the weight of the subsequent equipment such as the following carriage, and are not designed and laid in anticipation of transporting heavy objects. It is difficult to do so, and it is necessary to cut the blocks into pieces that can be transported. In addition, the steel member that has been gas cut cannot be reassembled or reused after being recovered.

  As a heavy material transport method and transport device in the tunnel to eliminate this, a rail member is laid along the axial direction at the bottom of the tunnel, and a heavy object (a part of a seal machine, etc.) is loaded on the rail member It is known that a sliding member is slidably mounted, a jack that expands and contracts in the tunnel axis direction is mounted on the sliding member, and an engagement / disengagement mechanism that engages and disengages the rail member on the expansion / contraction rod of the jack is known (patent) Literature 1 etc.).

  Hereinafter, a transport method and a transport apparatus for transporting the heavy object W (article) to the wellhead side of the tunnel T will be described.

  As shown in FIG. 8, an intermediate member 31 having a substantially disk-like (or donut-like plate-like) portion is attached to the right end of the heavy object W so as to cover the inner cylinder 6. One end of the connecting rod 32 is pin-connected, and the other end of the connecting rod 32 is pin-connected to a bracket 34 provided on another base 33 (hereinafter referred to as sub-base). On the sub-mount 33, a girder divided piece 15a obtained by dividing the previously removed ring girder 15 in the circumferential direction, a turning ring 17a of the erector 17, and the like are loaded.

  As shown in FIGS. 8 and 10, a total of four eaves members 29 are pin-supported and attached to the bottom of the sub-mount 33 with a space in the tunnel axis direction and a space in the tunnel width direction. Similarly, as shown in FIGS. 8 and 9, a total of four eaves members 29 are pin-supported and attached to the bottom of the main gantry 27 with an interval in the tunnel axis direction and an interval in the tunnel width direction. ing. A guide portion 35 is formed on the lower surface of each flange member 29. The guide portion 35 is recessed to engage with the rail 28. In the illustrated example, since a round bar is used for the rail 28, the cross-sectional shape of the guide portion 35 is a substantially semicircle. The rail 28 is directly laid on the segment 22 (made of steel or the like) and fixed by welding or the like.

  As shown in FIGS. 8 and 9, a plurality (six in the illustrated example) of shield jacks 16 previously removed are attached to the intermediate member 31 attached to the heavy object W at intervals in the tunnel circumferential direction. ing. Specifically, the jack 16 is disposed so as to face the tunnel center C in the cross section of the tunnel ring. At the tip of the telescopic rod 16b of the jack 16, a grip portion 37 is provided that moves in the tunnel radial direction by another jack 36 and engages / disengages with the tunnel inner surface (segment 22). In the illustrated example, the grip 37 has a recess formed so as to fit the main girder 22a of the segment 22 because the inner surface of the tunnel is the steel segment 22, but when the inner surface of the tunnel is a concrete segment, the segment You may have the convex part inserted in the bolt box hole recessedly provided in the segment internal peripheral surface in order to accommodate the volt | bolt which connects each other.

  In the apparatus for transporting a heavy article W in the tunnel having the above-described configuration, as shown by a broken line in FIG. The heavy load W moves in the tunnel axis direction by engaging with the beam 22a) and contracting the telescopic rod 16b using this as a clue. The feature of the present embodiment is that after the movement of the jack 16 by one stroke is completed, as a next clue, the expansion / contraction of any jack 16 is performed in order to engage the gripping portion 37 of any jack 16 with the inner surface of the tunnel. When the rod 16b is extended, a control unit 40 for maintaining the position of the heavy object W is provided by the gripping portion 37 of at least one of the remaining jacks 16 engaging the inner surface of the tunnel. There is in point.

  Then, by this control unit 40, the gripping portion 37 is detached from the inner surface of the tunnel so that the gripping portion 37 of the one jack 16 is engaged with the inner surface of the tunnel as the next clue, and the telescopic rod 16 b of the jack 16 is removed. When the handle is extended, the gripping portion 37 that has already been engaged and refilled at the position of the next clue is pressed outward in the tunnel radial direction by another jack 36 so that the position of the heavy object W is maintained. Yes. As a result, when the position of engagement of the gripping portion 37 of each jack 16 with the inner surface of the tunnel is changed, at least one gripping portion 37 is always engaged with the inner surface of the tunnel. Can be held.

  Therefore, even when the slope of the tunnel where the rail 28 is laid is steep, it is possible to prevent the mounts 27 and 33 from sliding on the rail 28 to the lower side. That is, this embodiment does not rely on the frictional force between the rail 28 and the flange member 29 to hold the position of the heavy object W, but always attaches at least one gripping portion 37 of the jack 16 to the inner surface of the tunnel. Since the position of the heavy object W is maintained by engaging with it, the tunnel gradient is steep, and the position of the heavy object W cannot be maintained only by the friction force, and the heavy object W slides down to the lower side. Even if this happens, this can be prevented.

  As described above, in this embodiment, since at least one gripping portion 37 is always engaged with the inner surface of the tunnel to prevent the heavy object W from slipping down in the steep tunnel, the gantry 27 and 33 and the rail The friction coefficient between the flange member 29 and the rail 28 can be made as small as possible by providing the flange member 29 between them. Therefore, the tow load of the jack 16 is reduced, and the number of jacks 16 attached to the heavy load W can be reduced.

  In the illustrated example, a plurality of jacks 16 are arranged at intervals in the tunnel circumferential direction. Since it is possible to arrange the gripping portion 37 at a position equidistant from the inner surface of the tunnel, it is possible to make the shapes of the plurality of gripping portions 37 all the same. Moreover, since it can arrange | position in the position near a tunnel inner surface, the holding part 37 can be made compact. Further, by always engaging at least two gripping portions 37 of the jack 16 with the inner surface of the tunnel, the heavy object W is held on the inner surface of the tunnel by the two or more gripping portions 37 spaced in the circumferential direction of the tunnel. Even if the tunnel is inclined, the heavy object W can be stably held.

  Here, if the grip portions 37 of two or more jacks 16 facing the tunnel center C in the tunnel ring section are moved outward in the radial direction of the tunnel and pressed against the inner surface of the tunnel, Since the engagement state is locked by the tension force of another jack 36 that moves the gripping portion 37 radially outward, even if the tunnel is steep (for example, 45 degrees or more, 90 degrees in the extreme) The weight W can be stably held without overturning. In the case of 90 degrees, the rail 28, the eaves member 29, and the gantry 27 are not necessary because they do not function, and the sub gantry 33 is suspended vertically below the heavy object W.

  Further, in the present embodiment, as shown in FIG. 9, six jacks 16 are arranged at intervals of 60 degrees, so that these three first jack groups at intervals of 120 degrees are shifted in phase by 60 degrees. This is divided into the same second jack group, and the three gripping portions 37 of either one of the jack groups are pressed against the inner surface of the tunnel from 36 with another jack, and this engagement state is separated into three separate jacks. The jack 36 is locked by the tension force (extension force). This is because the intersection of the axes of the jacks 36 coincides with the tunnel center C. Therefore, the problem of the rollover of the heavy object W in the steep tunnel can be solved as described in the previous stage. In addition, as long as the intersection of the axes of the jacks 36 coincides with the tunnel center C, the number and arrangement interval of the jacks 36 are not limited.

  Moreover, since the shield jack 16 removed from the shield machine 1 is used as the jack 16, the stroke of the telescopic rod 16b of the jack 16 is at least equal to one ring of the segment 22. Therefore, by extending / contracting the telescopic rod 16b, the gripping portion 37 provided at the tip of the telescopic rod 16b moves in the tunnel axis direction by a distance of at least one ring of the segment 22. Therefore, in order to engage the gripping portion 37 with the main girder 22a connecting the segments 22 in the tunnel axis direction and the similar main girder 22a adjacent thereto, the gripping portion 37 is connected to the telescopic rod 16b with respect to the tunnel axis. It is not necessary to swing in the direction, and it is sufficient to move the gripping portion 37 in the tunnel radial direction with another jack 36. As a result, the locking in the engaged state described above is achieved by the extension force of the other jack 36 facing (or at an interval of 120 degrees).

  Moreover, since the jack 16 is driven by a hydraulic device and uses the shield jack 16 removed from the shield machine 1 for the jack 16, the hydraulic equipment such as a pump unit provided in the shield machine 1 is connected to the jack 16. Can be used for hydraulic equipment.

  The present invention is not limited to the above-described embodiment. In FIG. 8, the weight 16 may be pushed out by the extension operation of the jack 16 with the direction of the jack 16 reversed left and right. The jack 16 may be attached, or the auxiliary mount 33 and the main mount 27 may be separated and the jack 16 may be attached to each.

  Further, the heavy object W is not limited to a part of the shield machine 1 (recovery part 1y), but may be various machines for tunnel construction, a rock mass, a concrete frame, or the like. Further, the jack 16 may be directly attached to the heavy object W (recovery portion 1y) without using the intermediate member 31.
