Description

  The present invention relates to a method for transporting a segment attached to a shield tunnel, and more particularly to a shield tunnel transshipment transport apparatus and method for transshipping segments in the middle of transport.

  When constructing a shield tunnel, the segments constituting the wall surface of the shield tunnel are transported in the face direction. Such segment transportation is performed, for example, by using a carriage loaded with segments. As an apparatus for conveying a segment, for example, there is a segment supply apparatus disclosed in Japanese Patent Laid-Open No. 6-88493. This segment supply apparatus has a hoist provided with a hoist beam provided between a conveyor provided behind the erector in the shield machine and a subsequent carriage on which the segment is mounted. By using this hoist, the segment mounted on the succeeding carriage can be smoothly supplied to the erector in the shield machine.

Another segment supply apparatus is disclosed in Japanese Patent Laid-Open No. 10-205294. In this segment supply device, a plurality of segments placed on a base table are received from a base table by a lifting device and placed on a rod. Thereafter, the segment is moved by moving the rod in the front-rear direction by a moving device.

  However, in the segment supply apparatus described in Patent Document 1, a hoist beam is disposed between the conveyor and the subsequent carriage. Here, since the number of segments that can be placed on the succeeding carriage on which the segments loaded on the succeeding carriage are mounted is limited, it is necessary to increase the number of carriages when trying to transport a large number of segments. Become. Thus, when the number of carriages is increased, it is necessary to lengthen the hoist beam in order to transfer the segment from the rear carriage.

  However, if the hoist beam is lengthened, the hoist beam cannot be provided in the portion where the curvature of the shield tunnel is large. Therefore, in the end, a large number of carriages cannot be arranged, and a large number of segments cannot be transported, so that there is a problem that it takes time to transport the segments.

  On the other hand, when the segment supply device disclosed in Patent Document 2 is used, a large number of segments can be transported at a time, so that the time required for transporting the segments can be reduced. However, the segment supply device disclosed in Patent Document 2 has a problem that the size of the device cannot be avoided.

  Accordingly, an object of the present invention is to enable a large number of segments to be transported at a time using a simple device, and thereby to shorten the segment transport time.

  In the segment transshipment transport apparatus according to the present invention that has solved the above-mentioned problems, a plurality of segment-equipped carriages on which the segments are mounted are arranged in the direction of excavation of the shield tunnel under construction, and between the segment entrance and the face in the shield tunnel A segment transporting means that moves between the segment loading port and the face, and a segment transshipment means that can lift the segment mounted on the segment-equipped carriage. After the mounted segment is lowered to the face side segment preparation position, the segment transport means is retracted to the segment transfer means position, and the segment mounted on the segment mounting carriage arranged at the rear of the segment transport means is moved by the segment transfer means. Lift and seg Retracting the cement conveying means, the segment lifted segment transhipment unit, in which reloading the segments mounted carriage disposed in the front segment conveying means.

  In the segment transshipment transport apparatus according to the present invention, the plurality of segment-equipped carriages include the segment transportation means arranged in parallel and the segment transshipment means that can lift the segments mounted on the segment-equipped carriage. After the segment mounted on the front segment mounting carriage is lowered to the face segment preparation position, the segment transport means is retracted to the position of the segment reloading means, and the segment mounted on the rear segment mounting carriage is moved to the front segment. Transship to the loaded truck. For this reason, at the face segment preparation position, the segments can always be loaded and unloaded from the front segment-equipped carriage. Therefore, for example, when a hoist beam is provided at the face side segment preparation position, the hoist beam can be shortened. Therefore, even in a tunnel having a large curvature, the segment can be transported by many carts. As a result, many segments can be transported at one time, thereby shortening the segment transport time.

  Further, as compared with the segment supply device disclosed in Patent Document 1, it is only necessary to provide segment transshipment means. For this reason, since the large apparatus as disclosed in Patent Document 2 is not required, the apparatus can be prevented from being enlarged.

  Here, the segment transshipment means includes a base disposed above the passage of the segment transporting means, and a gripping member that can be moved up and down and can grip the segment. can do.

  By using such a base and a gripping member, a suitable segment transshipping means can be obtained. As the base disposed above the passage of the segment transport means, a gate-type base straddling the passage of the segment transport means can be used. Further, it is also possible to use a base having a shape in which an L-shape is provided in which a beam disposed above the passage of the segment conveying means is supported from one side and a leg is provided on the other side.

  Moreover, it can be set as the aspect provided with the descent | fall distance restriction | limiting means which restrict | limits the descent | fall distance of a holding member.

  By providing such a descending distance limiting means, it is possible to prevent a situation in which, when the gripping member is lowered, it hits the ground or the segment cannot be gripped well.

  Furthermore, the segment transshipment means may be configured to be movable in the direction of excavation of the shield tunnel.

  Thus, since the segment transshipment means is movable, the segment transshipment means can also be advanced in accordance with the excavation of the shield tunnel. Therefore, since the distance between the shield machine and the segment transshipment means can be kept short, the segments can be transshipped in a short time.

  Further, in the method for transporting segments in the shield tunnel according to the present invention that has solved the above problems, the segment mounting carriage on which the segments are mounted is arranged side by side in the direction of excavation of the shield tunnel under construction. When transporting the segment by the segment transport means moving between the faces, after the segment mounted on the segment mounting carriage in front of the segment transport means is lowered to the face side segment preparation position, the segment transport means is moved to the segment transposition means position. The segment mounted means disposed on the rear of the segment transport means is moved by the segment transshipment means that is disposed between the segment loading port and the face and can lift the segment mounted on the segment loaded carriage. Lift the instrument, retracting the segments conveying means, the segment lifted segment transshipment means, and wherein the reloading into segments mounted carriage disposed in the front segment conveying means.

  Moreover, it can also be set as the aspect which moves a transshipment means to a face direction according to excavation of a shield tunnel.

  According to the transshipment and transport apparatus for shield tunnel segments according to the present invention, a simple apparatus can be used to transport many segments at a time, thereby shortening the segment transport time.

Thus, the position where the wheel 29 can travel is sequentially advanced as the shield machine 1 digs.

  A description will be given of a segment transshipment transport method for a shield tunnel according to the present embodiment having the above-described configuration.

  In the transshipment transport method according to the present embodiment, first, the segment S placed on the underground material storage in the vicinity of the vertical shaft is mounted on the segment mounting carts 11 to 14 by the segment mounting device. In addition, the segment S can also be set as the aspect directly mounted with the crane from the upper side of a vertical shaft, without being mounted in the underground material storage. Among these, the first and third segment mounted carriages 11 and 13 are loaded with the first third segment S1 to the third segment S3, and the second and fourth segment loaded carriages 12 and 14 are loaded with the fourth segment S4 to S4. A sixth segment S6 is mounted.

  Among these, the first segment S1 to the fifth segment S5 are segments of the same size, and the sixth segment S6 is a segment smaller than the other segments. These first segment S1 to sixth segment S6 constitute one ring when attached to the shield tunnel T.

  Thus, when the segments S1 to S6 are mounted on the segment mounting carriages 11 to 14, respectively, the locomotive 15 is driven and the segment mounting carriages 11 to 14 are transported to a position before the face. At this time, an occupant gets on the trolley for occupants as necessary.

  When the segments S1 to S6 are conveyed to the face, the segment moving device 5 moves the segments S1 to S6 mounted on the first and second segment mounting carriages 11 and 12 to the segment preparation position and loads them. At this time, the segments S1 to S6 mounted on the third and fourth segment mounted carriages 13 and 14 are left mounted on the third and fourth segment mounted carriages 13 and 14, respectively.

After the segments S1 to S6 mounted on the first and second segment mounted carriages 11 and 12 are loaded and unloaded, the segments S1 to S6 are left mounted on the third and fourth segment mounted carriages 13 and 14, respectively. Next, the locomotive 15 is driven, the segment-equipped carriages 11 to 14 are moved in the direction of the segment carry-in entrance , and stopped at the position of the setter 6. The setter 6 is movable, moves forward in accordance with the excavation by the shield machine 1, and is positioned in the vicinity of the shield machine 1. Specifically, it is located at a position moved from the shield machine 1 to the shaft side by about 100 to 150 m.

In the setter 6, the segments are transshipped. Hereinafter, the procedure of transshipment of segments will be described with reference to the drawings. The segment mounted carriages 11 to 14 conveyed by the locomotive 15 are
As shown in FIG. 6A, the locomotive 15 is stopped at a position where the locomotive 15 third segment mounting carriage 13 is disposed at the setter 6 position. At this time, the stop position of the third segment mounting carriage 13 is the position of the segments S1 to S3 mounted on the third segment mounting carriage 13 at approximately the center position of the front and rear arms of the left and right suspension arms 25 and 26 in the setter 6, respectively. The position where the longitudinal center position comes.

  When the third segment mounting carriage 13 stops at the position of the setter 6, the segments S <b> 1 to S <b> 3 mounted on the third segment mounting carriage 13 are transferred to the first segment mounting carriage 11. When performing this transshipment, first, as shown in FIG. 6B, the segments S1 to S3 mounted on the third segment mounting carriage 13 are gripped and lifted by the setter 6. The segments S1 to S3 are lifted as follows.

  First, as shown in FIG. 7A, the lift cylinder 24 is extended so that the lift saddle 23 is raised. At this time, the left and right suspension arms 25 and 26 are opened. In this state, positioning between the setter 6 and the third segment mounting carriage 13 is performed. Positioning between the setter 6 and the third segment-equipped carriage 13 is performed by visual observation of an operator.

  Now, the segments S1 to S3 are mounted on the third segment mounting carriage 13 in a state where the segments S1 to S3 are accurately positioned at the segment carry-in port in the vicinity of the shaft not shown. For this reason, positioning between the setter 6 and the segments S1 to S3 is completed by positioning between the setter 6 and the third segment mounting carriage 13. Positioning is performed between the setter 6 and the segments S1 to S3 so that the longitudinal center position of the segment S1 is exactly the center position of the front and rear arms of the left and right suspension arms 25 and 26, respectively.

  When the positioning between the setter 6 and the segments S1 to S3 is completed, the lift cylinder 24 is contracted and the lift saddle 23 is lowered as shown in FIG. When the lift saddle 23 is lowered, the lowering positions of the left and right suspension arms 25 and 26 are adjusted by the limit switch SW so that the suspension hooks 27 and 28 are positioned slightly below the first segment S1.

  Then, as shown in FIG. 8A, a slide cylinder (not shown) is driven to move the left and right suspension arms 25 and 26 inward, and the suspension hooks 27 and 28 are disposed below the first segment S1. So that When the left and right suspension arms 25 and 26 are slid, a segment limit switch (not shown) adjusts the distance between the left and right suspension arms 25 and 26 to be substantially the same as the width of the segments S1 to S3.

  Thus, when the left and right suspension arms 25 and 26 are slid so as to have an appropriate width, the lift cylinder 24 is extended and the lift saddle 23 is raised as shown in FIG. As the lift saddle 23 rises, the segments S1 to S3 held by the suspension hooks 27 and 28 are lifted upward.

  When the segments S1 to S3 are lifted, as shown in FIG. 9A, the segments S1 to S3 mounted on the third segment mounting carriage 13 disappear, and the third segment mounting carriage 13 becomes empty. When the third segment mounting carriage 13 becomes empty, the locomotive 15 is moved backward in the shaft direction, and the first segment mounting carriage 11 is stopped at the position of the setter 6.

  When the first segment mounting carriage 11 is stopped at the position of the setter 6, as shown in FIG. 9B, the first segment mounting carriage is installed in the same procedure as when the third segment mounting carriage 13 and the setter 6 are positioned. The carriage 11 and the setter 6 are positioned. Thereafter, the lift cylinder 24 in the setter 6 is contracted, and the lift saddle 23 is lowered.

  As the lift saddle 23 is lowered, the left and right suspension arms 25 and 26 are lowered, and the segments S1 to S3 are mounted on the first segment mounting carriage 11. When the segments S1 to S3 are mounted on the first segment mounting carriage 11, the left and right suspension arms 25 and 26 are moved outward by the slide cylinder, respectively, and the segments S1 to S3 are released from the gripping state by the suspension hooks 27 and 28. Thereafter, the lift cylinder 24 is extended, and the lift saddle 23 is once raised.

  Subsequently, as shown in FIG. 9C, the segment mounted carriages 11 to 14 are moved forward in the face direction by the locomotive 15, and the fourth segment mounted carriage 14 is stopped at the setter 6 position. On the fourth segment mounting carriage 14, segments S4 to S6 are mounted. The segments S4 to S6 are transshipped to the second segment mounting carriage 12.

  The procedure for reloading the segments S4 to S6 mounted on the fourth segment mounted carriage 14 to the second segment mounted carriage 12 is to transfer the segments S1 to S3 mounted on the third segment mounted carriage 13 to the first segment mounted carriage 11. The procedure is the same. Accordingly, the lift saddle 23 is lowered by contracting the lift cylinder 24, and then a slide cylinder (not shown) is driven to move the left and right suspension arms 25 and 26 in the directions close to each other. The four segments S4 are gripped.

  In this state, the lift cylinder 24 in the setter 6 is extended to raise the lift saddle 23. When the lift saddle 23 is raised, as shown in FIG. 10A, the segments S4 to S6 mounted on the fourth segment mounting carriage 14 are raised, and the fourth segment mounting carriage 14 becomes empty. When the fourth segment mounting carriage 14 becomes empty, the locomotive 15 is moved backward in the shaft direction, and the segment mounting carriages 11 to 14 are moved.

  Then, as shown in FIG. 10B, the second segment mounting carriage 12 is positioned at the setter 6 to position them. Thereafter, as in the case where the segments S1 to S3 are mounted on the first segment mounting carriage 11, the lift cylinder 24 in the setter 6 is contracted and the lift saddle 23 is lowered. By lowering the lift saddle 23, the segments S4 to S6 are lowered and mounted on the second segment mounting carriage 12, as shown in FIG. 10 (c). Thereafter, the segments S4 to S6 are released from the gripped state by the hanging hooks 27 and 28, and the transshipment operation of the segments S4 to S6 is completed.

  When the segments S1 to S3 are transferred from the third segment mounted carriage 13 to the first segment mounted carriage 11 and the segments S4 to S6 are transferred from the fourth segment mounted carriage 14 to the second segment mounted carriage 12, the locomotive is 15, the segment-equipped carriages 11 to 14 are advanced in the face direction. After that, when the first segment mounting carriage 11 reaches the position before the face, the segment moving device 5 moves the segments S1 to S6 mounted on the first and second segment mounting carriages 11 and 12 to the segment preparation position and unloads them. .

  Finally, the transportation to the segment preparation position in the vicinity of the face of the segments S1 to S6 for the two rings mounted on the segment mounting carts 11 to 14 is completed, and the segment mounting carts 11 to 14 are moved by the locomotive 15. Transport to material storage near the shaft. Further, as the shield tunneling machine 1 advances the shield tunnel T, the shield machine 1 moves forward. By moving the setter 6 forward in accordance with the advancement of the shield machine 1, the segment mounted carriages 11 to 14 are moved forward. The amount of movement can be reduced.

  Thus, in the segment transshipment transport apparatus according to the present embodiment, when the segments S1 to S6 are loaded and unloaded by the hoist 3, the segments S1 to S6 are always positioned in front of the first segment mounted carriage 11 and It is in a state of being mounted on the second segment mounting carriage 12. For this reason, even when a plurality of four trucks are connected to carry a large number of segments, the beam 4 in the hoist 3 can be shortened. Therefore, even when constructing a shield tunnel having a large curvature, a large number of segments can be transported at one time, and the segment transport time can be shortened.

  Moreover, when transshipment of segment S1-S4, the setter 6 arrange | positioned rather than the shield machine 1 at the shaft side is used. For this reason, since this setter 6 should just be provided, it can be completed with a simple apparatus.

  The preferred embodiment of the present invention has been described above, but the present invention is not limited to the above embodiment. For example, in the above-described embodiment, four segment mounting carts are connected. However, two, three, or five or more segment mounting carts may be connected. Moreover, in the said embodiment, although the setter which can perform only the transshipment of the segment mounted in one segment mounting trolley is used, the segment mounted in the two or more segment mounting trolleys is carried out at once. A setter that can be reloaded can also be used.

  Moreover, in the said embodiment, although it is set as six segments with 1 ring, the number of the segments which form 1 ring is not limited to this number. Furthermore, the number of segments mounted on the segment mounting carriage is not limited to three as in the above embodiment, and can be set to an appropriate number.

  In the above embodiment, the segments are mounted in one row on the segment-equipped carriage, but depending on the relative width between the segments and the segment-equipped carriage, two or more segments are mounted on the segment-equipped carriage. It can also be set as the aspect to do. When mounting two or more rows of segments, it is difficult to lift the segments directly with a setter, but by mounting two or more rows of segments on a single pallet, The segment can be easily lifted by lifting the pallet with a setter.

  On the other hand, when the segments are transshipped in the setter, the segment-equipped carriage is moved in the above embodiment, but the setter may be moved forward and backward. Furthermore, although the segment transshipment transport apparatus according to the present embodiment is suitable for constructing a shield tunnel having a large curvature, for example, even when constructing a linear shield tunnel, for example, ten segment-mounted carriages In the case of a large number of connections, the length of the hoist beam can be kept short. Therefore, even when constructing a linear shield tunnel, it can be suitably used.
