JP, 2016-84681, A

  In the case of excavating construction of outer shell tunnels described in the above-mentioned Patent Document 1, in order to excrete a plurality of outer shell tunnels in parallel, with respect to a plurality of excavating machines, materials and equipment can be timely without delay by the transport device. It is necessary to supply. In order to do so, it is necessary to load materials and equipment into the transport device in a timely manner without delay.

  However, since the transport apparatus is provided around the underground structure (underground), when transporting the equipment from the ground via a tunnel or a shaft, a shift in the arrival timing of the equipment tends to occur. As a result, if the timing at which the equipment is needed on the excavator side does not coincide with the timing at which the equipment arrives from the ground, it is efficient to excavate the outer shell tunnel even if the transportation speed from the transport device to the excavator is increased. Not be able to Therefore, conventionally, there is a problem that it is difficult to supply materials and materials in a timely manner without delay over the entire supply route of materials and materials from the ground to the excavator via the transfer device.

  The present invention has been made to solve the above-described problems, and one object of the present invention is to provide a system for supplying all of the materials from the ground to the excavator via the transport device. An object of the present invention is to provide a transport system for constructing an outer shell tunnel capable of performing equipment supply in a timely manner without delay.

  In order to achieve the above object, the transport system for constructing an outer shell tunnel according to the present invention is a system for transporting materials and materials used for excavating a plurality of outer shell tunnels around an underground structure to an excavator. , A circular transportation device which carries materials and equipment at the mounting position and moves in a circumferential start base extending in the circumferential direction of the underground structure, and provided on a transportation route of materials and materials passing through the underground structure, The equipment storage unit that can store multiple items of equipment and materials, a connection passage that connects the supply position of materials and materials from the equipment storage unit, and the mounting position of the circumferential start base And a connected transfer device for supplying materials to the moved circumferential transfer device from the supply position.

  In the present specification, the underground structure is a broad concept including a tunnel, a underground facility, and a structure in which an underground cavity is formed. The outer periphery of the underground structure means the periphery surrounding the underground structure in the vertical cross section of the underground structure. Excavators include, for example, shield excavators, and the materials and equipment in that case are segments (blocks constituting the tunnel pit wall) used in the shield construction method, rails constituting the transport path laid in the excavated area of the shell tunnel, Including sleepers and the like. The equipment storage unit is a broad concept including, for example, a storage (storage warehouse) for storing materials and equipment, as well as a storage area by arranging and arranging carts and pallets loaded with materials and equipment.

  In the outer shell tunnel construction transportation system according to the present invention, the materials and equipment transported from the ground supply facility through the transportation route in the underground structure are provided by providing the above-described equipment storage section and the connection transportation device. It can be temporarily stored in the equipment storage department. Therefore, even if the timing at which the equipment and materials reach from the ground supply facility does not coincide with the timing at which the equipment and equipment are needed on the excavator side, the timing difference is absorbed by temporary storage in the equipment and materials storage unit, and the excavator is Equipment can be supplied at the same timing as equipment needs. Then, through the connection passage, the materials and materials supplied from the materials and materials storage unit are moved by the connection and conveyance device to the loading position according to the timing at which the materials and materials are needed on the excavating machine side. Can be supplied. As a result, according to the present invention, materials and materials can be supplied in a timely manner without delay over the entire supply route of materials and materials from the ground to the excavator via the circumferential transfer device.

  In the outer shell tunnel construction transportation system according to the above invention, preferably, the equipment storage unit classifies any of the plurality of storage units by classifying the transported materials and equipment and a three-dimensional storage having a plurality of storage units arranged vertically. The apparatus further includes a carry-in mechanism for carrying in the bag and a carry-out mechanism for carrying out the equipment stored in the storage unit to the supply position. According to this structure, the equipment can be stored by using the space in three dimensions by the three-dimensional storage, so that more equipment can be stored at the supply position. Therefore, even within the limited space in the underground structure, it is possible to secure a sufficient storage amount of materials and equipment to absorb the difference between the time when materials are needed and the time when materials arrive. . In addition, since materials and equipment can be classified into a plurality of storage parts and stored according to types, storage quantities of various kinds of materials and materials used for excavating an outer shell tunnel can be easily grasped. As a result, processing such as sending a replenishment instruction of materials and equipment to the ground supply equipment can be easily performed according to the amount of use of each kind of materials and equipment. The equipment can be supplied stably.

It is provided along with the second transport route for transporting the transported object without passing through, and the connection transport device supplies the equipment at the supply position to the loading position, and transports transported from the second transport route. It is configured to supply an object to the mounting position. According to this structure, the materials and equipment and the articles not stored in the material storage unit can be supplied through different routes. Therefore, it is difficult to store or transpose in the equipment storage section, and the second transport route is used for a large and heavy transport such as an excavator main body or a component of the excavator that does not necessarily need to be stored. From the above, it is possible to transport only the materials which need to secure a plurality of stocks to the material storage section through the first transportation route while supplying directly to the circumferential transfer device. In addition, since it is not necessary to enlarge the equipment storage unit unnecessarily in order to be able to store transported items such as large heavy objects, the underground structure can be prevented by suppressing the enlargement of the equipment storage unit. You can efficiently use the limited space inside.

  In the shell tunnel construction transportation system according to the above invention, preferably, the connection passage includes a first passage extending from the supply position to the mounting position and a second passage different from the first passage extending from the mounting position to the supply position. The connecting and conveying device is a circulating passage, and the loading and unloading of the load in the circumferential conveying device at the loading position through the second passage and the loading of the equipment to the loading position through the first passage are parallel to each other. Is configured to be feasible. Here, for example, when there is only a single connection passage, if there is a load to be collected from the circumferential transfer device, after loading the load by the connection passage, it is necessary to load materials and materials by the same connection passage. It occurs. On the other hand, when the connection passage includes the first passage and the second passage, immediately after the load to be collected is sent out to the second passage, the materials and materials are promptly loaded from the first passage into the circumferential conveyance device. be able to. As a result, it is possible to shorten the time required to load the materials and materials into the circumferential transfer device, and to quickly transfer the materials and materials to the excavator.

  In the outer shell tunnel construction transportation system according to the above invention, preferably, the circumferential transportation device is configured to carry a carriage loaded with materials and moved, and the connection transportation device is a circumferential transportation device at the mounting position. The carriage having been transported from there is sent out to the second passage, and the carriage loaded with materials and materials is sent from the first passage to the circumferential conveyance device. According to this structure, the materials to be transferred to the circumferential transfer device can be obtained simply by replacing the empty carriage (the empty carriage loaded with the materials and materials) transported by the circumferential transfer device with the carriage on which the materials and materials are loaded. You can load it. Then, since the replacement of the carriages can be performed from the separate passages by the first passage and the second passage, the time required for loading the materials and materials to the circumferential conveyance device can be further shortened. In addition, since the loading time is shortened, there is a time allowance for the conveyance of the circumferential conveyance device, and it is possible to flexibly cope with the difference between the timing when the equipment is needed and the timing when the equipment arrives. It becomes possible.

  In the outer shell tunnel construction transportation system according to the above invention, preferably, operation information of the excavating machine, operation information of the circumferential conveying device, and operation information of the equipment storage section are respectively collected, and resources are provided according to the operation of the excavating machine. The equipment storage unit is configured to supply materials and equipment, and the transportation request for materials and equipment to the material and equipment storage unit is output to the ground supply facility so that the equipment and materials storage unit can ensure the specified quantity of materials and equipment. , And a logistics management unit. Here, in particular, in the case where a plurality of excavators excavate an outer shell tunnel simultaneously in parallel, and the materials are transported in parallel to the respective excavators by the circumferential transfer device, the respective excavating conditions are not necessarily required. The disagreement makes it difficult to manage the supply and demand of materials and equipment. Therefore, according to the above-described physical distribution management unit, the demand and supply of materials and materials in the outer shell tunnel construction transportation system can be integratedly managed based on the respective operation information. As a result, the transportation operation of the equipment storage unit, the circumferential conveyance device, and the connection conveyance device according to the timing when the equipment is needed is realized, and the stock amount that can be coped with at the timing when the equipment is needed is always secured. It is possible to adjust the timing of arrival of equipment from ground supply equipment as

Do. While one of the travel drive mechanisms 17a and 17b drives the self-propelled conveyance device 12, the other causes the lock mechanism 18a in the disengaged state to extend or contract by the cylinder mechanism 18b to prepare for the next drive. Next, the self-propelled transfer device 12 is moved in the traveling direction by extending or contracting the cylinder mechanism 18b in a state where the other is fixed to the rail 13 by the lock mechanism 18a. In the meantime, one prepares for the next drive by switching the lock mechanism 18a to the disengagement state and extending or contracting. By alternately repeating driving of the self-propelled conveying device 12 in the traveling drive mechanisms 17a and 17b, the self-propelled conveying device 12 can continuously move the circumferential traveling passage 11 clockwise or counterclockwise. .

  The travel drive mechanism 17 may be configured by, for example, a gear drive system. That is, the traveling drive mechanism 17 may be configured to include a pinion gear and a motor for driving the pinion gear. In this case, a rack gear extending in the circumferential direction is provided on the side surface of the outer rail 13 a of the circumferential runway 11. It is possible to move the self-propelled transfer device 12 in the circumferential direction along the circumferential travel path 11 by rotating the pinion gear that meshes with the rack gear by the travel drive mechanism 17.

Note that the supply position P1 is a position that is aligned horizontally with the mounting position P2. In the example of FIG. 1, the supply position P1 and the mounting position P2 are arranged in the horizontal direction (X direction) orthogonal to the access tunnel 1b in the horizontal plane. Since the supply position P1 and the mounting position P2 are arranged side by side, the connection passage 31 has the supply position P1 and the mounting position P2 compared to the case where the supply position P1 is on the front or back side of the access tunnel 1b in the Y direction. And can be connected by the shortest distance.

  In the first embodiment, as shown in FIG. 7, the connection passage 31 includes a first passage 31a from the supply position P1 to the mounting position P2 and a second passage 31b from the mounting position P2 to the supply position P1. It is a passage. The second passage 31 b is a passage different from the first passage 31 a.

  Further, in the first embodiment, the circumferential conveyance device 10 is configured to be mounted and moved by the carriage 35 on which the equipment 5 is loaded. That is, in the self-propelled conveyance device 12, the equipment 5 is loaded on the carriage 35 together with the equipment 5.

  Specifically, the connection passage 31 includes a passage portion 32a, a passage portion 32b, a passage portion 32c, a passage portion 32d, and a passage portion 32e. Each of the passage portions 32a to 32e is a runway on which the traverser carriage 33 can travel, and extends linearly. The passage portion 32a, the passage portion 32b, and the passage portion 32c extend in the front-rear direction (Y direction) along the access tunnel 1b. The passage portion 32a is connected to the supply position P1, and the passage portion 32c is connected to the mounting position P2. The passage portion 32 b is disposed between the passage portion 32 a and the passage portion 32 c. The passage portion 32d and the passage portion 32e extend in the lateral direction (X direction) orthogonal to the access tunnel 1b. The passage portion 32d is connected to the supply position P1 and connects the passage portion 32a and the passage portion 32b. The passage portion 32e is provided on the back side of the supply position P1 and connects the passage portion 32a, the passage portion 32b, and the passage portion 32c. As can be seen from FIG. 7, a rectangular circulation passage is constituted by the passage portion 32a, the passage portion 32b, the passage portion 32d and the passage portion 32e.

  In the configuration example of FIG. 7, the first passage 31a is a passage that reaches the mounting position P2 from the supply position P1 through the passage portion 32d, the passage portion 32b, the passage portion 32e, and the passage portion 32c. The second passage 31b is a route that reaches the supply position P1 from the mounting position P2 through the passage portion 32c, the passage portion 32e, and the passage portion 32a.

  The traverser carriage 33 is a carriage that can move on the passage portions 32a to 32e, and is, for example, a self-propelled carriage that incorporates a drive unit such as a motor. The traverser cart 33 can move in a state where the cart 35 carrying the equipment 5 is loaded. In the example of FIG. 1 and FIG. 7, three traverser carts 33 are arranged.

  With such a configuration, the connection conveyance device 30 unloads the load in the circumferential conveyance device 10 at the mounting position P2 through the second passage 31b, and the equipment and materials to the mounting position P2 through the first passage 31a. It is configured to be able to be carried out in parallel with the 5 loadings.

  Then, the connected transfer device 30 sends out the transferred carriage 35 (hereinafter referred to as an empty carriage 35b) from the circumferential transfer device 10 at the loading position P2 to the second passage 31b and loads the equipment 5 (hereinafter, loading) The carriage 35 a) is configured to be fed into the circumferential transfer device 10 from the first passage 31 a.

  That is, when the self-propelled conveyance device 12 moves to the loading position P2, the empty carriage 35b is sent out from the self-propelled conveyance device 12 to the traverser carriage 33. The traverser carriage 33 carrying the empty carriage 35b passes through the second passage 31b which moves the passage portion 32e to the passage portion 32a.

  The loading carriage 35a is prepared on the traverser carriage 33 at the supply position P1. When the traverser carriage 33 carrying the empty carriage 35b moves past the passage portion 32b toward the passage portion 32a, the traverser carriage 33 carrying the loading carriage 35a passes through the first passage 31a for moving the passage portion 32d and the passage portion 32b. Is fed into the self-propelled transfer device 12 at the loading position P2.

  Thereafter, the traverser carriage 33 carrying the empty carriage 35b is moved to the supply position P1 through the passage portion 32a, and loading of the next material 5 with the empty carriage 35b is performed.

  As shown in FIG. 1, the transport route 60 is provided separately with a route for transporting the equipment 5 and a route for transporting the article 7 such as the shield machine 6. That is, the transport route 60 has a first transport route 60 a for transporting the materials 5, and a second transport route 60 b for transporting the articles 7 without passing through the material storage unit 20. The first transport path 60 a and the second transport path 60 b are provided in parallel, and merge with the forward path 62 and the return path 63 at the branch portion 64. In the branch portion 64, the tunnel carriage 61 from the forward path 62 is distributed to the first transport path 60a or the second transport path 60b according to the mounted object.

  The equipment storage unit 20 is connected to a first transportation route 60 a for transporting the equipment 5 in the transportation route 60. In addition, the equipment storage unit 20 is provided alongside the second transport path 60 b for transporting the transported object 7 without passing through the equipment storage unit 20 among the transport paths 60. The transported object 7 is sent to the construction site of the shell tunnel 2 by the circumferential transportation device 10 without being stored in the equipment storage unit 20. The conveyed product 7 (see FIG. 6) is, for example, a large heavy load such as a main body of the shield machine 6 or a component of the shield machine 6 which is divided and conveyed. Such a transport object 7 is transported, for example, when drilling of the shell tunnel 2 is newly started, and there is no need to maintain and supply a fixed cycle time during drilling, so the equipment storage section The need for stockpiling at 20 is low. For this reason, the conveyed product 7 is directly transported to the connection transport device 30 from the second transport path 60 b aligned with the equipment storage unit 20.

  The connection conveyance device 30 is configured to supply the equipment 5 at the supply position P1 to the mounting position P2, and to supply the conveyance object 7 transported from the second transport path 60b to the mounting position P2.

  Specifically, a gantry crane 65 (see FIG. 6 and FIG. 7), which is a transfer device for carrying in the shield machine 6, is provided at the end position of the second transport path 60b. The conveyed product 7 is transferred by the gantry crane 65 to a not-shown carriage for transporting heavy goods, and is loaded onto the circumferential conveyance device 10 via the connection passage 31.

  In addition, in conveyance of the shield machine 6, both division | segmentation conveyance which divides and conveys the components of the shield machine 6 in multiple times, and integral conveyance which conveys a finished product are included. When divided and transported, components of the shield machine 6 are assembled by the gantry crane 65 into the predetermined size transported by the self-propelled transport device 12, and then the traverser carriage 33 of the connection transport device 30 mounts the loading position P 2. It is mounted on the self-propelled transfer device 12.

(Supply and demand management of materials and materials in transport system)
As shown in FIG. 8, in the first embodiment, the transport system 100 includes a physical distribution management unit 40 for managing the supply process of the materials 5.

  The physical distribution management unit 40 has a function of supplying the equipment 5 from the equipment storage unit 20 according to the operation of the shield machine 6. That is, according to the operation of the shield machine 6, the physical distribution management unit 40 uses the material 5 from the circumferential transfer device 10 to the shield machine 6 at the timing according to the timing when the material 5 is necessary during digging. Necessary materials 5 are sent out from the material storage unit 20 so that the material can be transported. That is, based on the timing at which the equipment 5 in the shield machine 6 is required and the cycle time of the conveyance operation of the circumferential conveyance device 10 in the circumferential start base 3, the physical distribution management unit 40 Manage the supply of equipment 5 The timing at which the equipment 5 in the shield machine 6 becomes necessary by mounting the equipment 5 sent from the equipment storage unit 20 on the self-propelled conveyance device 12 moved to the mounting position P2 by the connection conveyance device 30 Supply of the equipment 5 corresponding to is performed.

  In addition, the physical distribution management unit 40 has a function of outputting a transportation request of the equipment 5 to the equipment storage unit 20 to the ground supply facility 70 so that the equipment 5 of the specified quantity is secured in the equipment storage unit 20. . That is, the physical distribution management unit 40 can supply the materials 5 at a timing according to the timing at which the materials 5 are needed, so that the materials storage unit 20 may have more than a predetermined number of materials 5 set in advance. The stock management of the equipment storage unit 20 is performed so as to be stored in the

  Specifically, the physical distribution management unit 40 grasps the quantity of the equipment 5 stored in the equipment storage unit 20 for each kind of the equipment 5 and A transportation request including the quantity is issued to the ground supply facility 70.

  In addition to the above processing, the physical distribution management unit 40 also performs processing such as extraction of materials 5 necessary for excavation, determination of the transport order to each shield machine 6, determination of the operation route of each device, and the like.

  The distribution management unit 40 collects the operation information 41 for the processing of the distribution management. The operation information 41 includes operation information of the shield machine 6, operation information of the circumferential conveyance device 10, and operation information of the equipment storage unit 20. Preferably, the operation information 41 includes operation information of the connection transfer device 30. The physical distribution management unit 40 performs the supply of the material 5 from the material storage unit 20 and the transport request of the material 5 to the ground supply facility 70 based on the collected operation information 41.

  The operation information of the shield machine 6 is, for example, job information indicating the current work status such as whether it is excavating or assembling a segment. The shield machine 6 basically forms the outer shell tunnel 2 by repeating two steps of digging work for a predetermined distance and assembly of a segment to the spot where the digging has been performed. Therefore, a typical example of the work that requires the equipment 5 is the assembly of segments. When the shield machine 6 is digging, information on the current advancing distance is also acquired, and the time required for the next segment assembly (the demand timing of the equipment 5) is grasped.

  As the operation information of the circumferential transfer device 10, for example, in which position of the self-propelled transfer device 12 is in the circumferential start base 3 or before or after the transfer of the materials 5 to the transfer destination? Job information indicating the current work status such as. From the operation information of the circumferential conveyance device 10, the time required for each self-propelled conveyance device 12 to reach the mounting position P2 next is grasped. Further, as individual information of each self-propelled transfer device 12, the type and quantity of the equipment 5 to be mounted on the self-propelled transfer device 12 reaching the loading position P2 next are grasped. Next, the equipment 5 to be mounted on the self-propelled conveying device 12 that reaches the mounting position P2 is the next type of shield machine 6 that the self-propelled conveying device 12 carries from the operation information of the shielding machine 6 It is grasped by whether the equipment 5 of the above is needed.

  The operation information of the equipment storage unit 20 includes the type of the equipment 5 to be stored and the current quantity for each type. Based on the comparison between the current quantity and the predetermined quantity to be secured, it is possible to know which kind of equipment 5 should be required for the ground supply facility 70 and in what quantity.

  As the operation information of the connection transfer device 30, for example, the position of the traverser carriage 33 (which carries the loading carriage 35a) for transporting the equipment 5 to be loaded next to the self-propelled transfer device 12 and the empty carriage 35b are loaded. It is information of each traverser carriage 33 such as the position of the traverser carriage 33.

  The physical distribution management unit 40 (see FIG. 3A) is a computer system constructed in, for example, a management center on the ground that manages the entire excavation work of the outer shell tunnel 2 or the like. The management center is provided together with a ground supply facility 70 and the like for stocking the equipment 5 on the ground. Although details will be omitted, each operation information may be obtained by using an information network constructed by wired, wireless, or a combination of each of the shield machine 6, the self-propelled transfer device 12, the equipment storage unit 20 and the connection transfer device 30. It is acquired from the information processing apparatus (not shown) with which each is equipped.

  For example, when a plurality of shield machines 6 such as four machines are operated simultaneously in parallel to construct a plurality of outer shell tunnels 2 simultaneously, a large number of operation information 41 is simultaneously generated. Smooth work progress becomes difficult. The physical distribution management unit 40 integrally manages various types of operation information 41 of the entire transfer system 100, and the smooth operation of the transfer system 100 becomes possible.

(Operation of transport system)
Next, with reference to FIG. 9, the operation of the transport system 100 of the first embodiment will be described. In FIG. 9, for example, an example will be considered in which four shield machines 6 are operated in parallel simultaneously, and the materials 5 are transported by four self-propelled transport devices 12 for each shield machine 6. It is assumed that the cycle of timing at which the equipment 5 is required in each shield machine 6 is 60 minutes. In this case, the materials 5 are transported to any one of the shield machines 6 at timings shifted every 15 minutes so that the demand timings of the four shield machines 6 are not simultaneously reached.

  The four self-propelled transfer devices 12 may be moved in the circumferential direction (direction C) with a cycle time of 60 minutes in accordance with the timing at which the equipment 5 is required, and the equipment 5 may be transported. However, at the loading position P2, it is not possible to simultaneously load the materials 5 on the four self-propelled transfer devices 12, and it is necessary to perform the loading operation in order. For this reason, at the loading position P2, it is necessary to load the equipment 5 within the cycle time of every 15 minutes, and the loading operation time is also included in the transfer cycle time. It is necessary to secure a stable stock.

  However, the timing at which the equipment 5 arrives from the ground supply facility 70 is different from the demand timing, or there are cases where a large amount of equipment 5 is transported batchwise in a cycle longer than the cycle of the demand timing. It is possible. In particular, when the distance of the transportation route 60 from the ground supply facility 70 to the supply position P1 is long, a mismatch between the timing at which the equipment 5 arrives and the timing at which the equipment 5 is needed tends to occur. Even in that case, in the first embodiment, the materials 5 are temporarily stored by the material storage unit 20 provided at the supply position P1 directly connected to the transport path 60. As a result, a state in which the equipment 5 can be constantly supplied at the supply position P1 is secured, and it becomes possible to cope with the supply of the equipment 5 in a cycle time of 15 minutes.

  Further, in the first embodiment, the loading carriage 35a on which the equipment 5 to be loaded next is loaded in advance is prepared by the connection transfer device 30 in the first path 31a. Then, when the self-propelled conveyance device 12 reaches the mounting position P2, the empty carriage 35b that has been mounted is delivered to the second passage 31b, and the loading carriage 35a from the first passage 31a to the self-propelled conveyance device 12 is Delivery is done. That is, the installation of the equipment 5 is completed only by replacing the carriage 35 mounted on the self-propelled transfer device 12. Therefore, the mounting operation is completed in a short time, and the self-propelled transfer device 12 is sent out toward the shield machine 6 of the transfer destination.

  Also in the shell tunnel 2 of the transfer destination, a transfer path 2a for moving the carriage is constructed in the tunnel. Therefore, the self-propelled transfer device 12 can transfer the materials 5 only by sending out the loaded loading carriage 35 a into the tunnel at the tunnel entrance of the circumferential start base 3. After the loading truck 35 a reaches the position of the shield machine 6 and the equipment 5 is loaded and unloaded, the loaded and unloaded empty truck 35 b is returned to the self-propelled transfer device 12. Thereafter, the self-propelled transfer device 12 moves in the circumferential start base 3 again toward the mounting position P2.

(Effect of the first embodiment)
In the first embodiment, the following effects can be obtained.

  In the first embodiment, as described above, materials and equipment transported from the ground supply facility 70 through the transportation route 60 in the underground structure 1 by providing the equipment storage unit 20 and the connection conveyance device 30. 5 can be temporarily stored in the equipment storage unit 20. Therefore, even if the timing at which the equipment 5 arrives from the ground supply facility 70 does not coincide with the timing at which the equipment 5 is required on the shield machine 6 side, the timing difference is absorbed by temporary storage in the equipment storage unit 20. Then, the equipment 5 can be supplied at a timing according to the timing at which the equipment 5 is required on the shield machine 6 side. Then, the circumferential conveyance has moved the equipment 5 supplied from the equipment storage unit 20 by the connection conveyance device 30 to the mounting position P2 at a timing according to the timing at which the equipment 5 is needed on the shield machine 6 side. The device 10 can be supplied via the connection channel 31. As a result, according to the transfer system 100 of the first embodiment, the supply of the materials 5 is not delayed over the entire supply route of the materials 5 from the ground to the shield machine 6 via the circumferential transfer device 10. Can be done.

  In the first embodiment, as described above, the material storage unit 20 is provided with the three-dimensional storage 21, the loading mechanism 22, and the unloading mechanism 23. As a result, since the equipment 5 can be stored by using the space three-dimensionally by the three-dimensional storage 21, more equipment 5 can be stored at the supply position P1. Therefore, even within the limited space in the underground structure 1, a sufficient storage amount of the equipment 5 is secured to absorb the difference between the timing at which the equipment 5 is required and the timing at which the equipment 5 arrives. can do. Moreover, since the equipment 5 can be classified into a plurality of storage parts 21a and stored according to type, the storage amount of various kinds of equipment 5 used for excavation of the shell tunnel 2 can be easily grasped. . As a result, processing such as sending a replenishment command to the ground supply facility 70 can be easily performed according to the amount of use of each type of material and equipment 5, so even if there are many types of materials and materials 5, various resources The equipment 5 can be stably supplied.

  In the first embodiment, as described above, the equipment storage unit 20 is connected to the first transport route 60 a of the transport route 60, and the article 7 is transported without passing through the equipment storage unit 20. It is provided side by side with the second transport route 60b. Then, the connecting and transporting apparatus 30 is configured to supply the equipment 5 at the supply position P1 to the mounting position P2 and to supply the transported object 7 transported from the second transport path 60b to the mounting position P2. As a result, the equipment 5 and the conveyed product 7 such as a component of the shield machine 6 can be supplied through different routes. Therefore, while it is difficult for storage and transshipment in the equipment storage unit 20, it is not always necessary to store the goods 7 such as the heavy shield such as the shield machine 6 main body and the components of the shield machine 6, It is possible to transport only the equipments 5 required to secure a plurality of stocks to the equipment storage section 20 through the first transportation path 60a while supplying the second transportation path 60b directly to the circumferential transportation device 10. In addition, since it is not necessary to make the equipment storage unit 20 unnecessarily large in order to be able to store the transport object 7 such as a large heavy load, it is possible to suppress the enlargement of the equipment storage unit 20. The limited space in the underground structure 1 can be used efficiently.

  In the first embodiment, as described above, the connection passage 31 is configured as a circulation passage including the first passage 31a and the second passage 31b, and the connection conveyance device 30 is mounted via the second passage 31b. The loading of goods and the loading of the equipment 5 through the first passage 31a can be performed in parallel. Here, for example, when there is only a single connection passage 31 and there is a load to be collected from the circumferential transfer device 10, after the load is unloaded by the connection passage 31, It will be necessary to load it. On the other hand, when the connection passage 31 includes the first passage 31a and the second passage 31b, immediately after the loaded object to be collected is sent out to the second passage 31b, the equipment 5 can be quickly taken from the first passage 31a. The circumferential transfer device 10 can be loaded. As a result, it is possible to shorten the time required for loading the materials 5 into the circumferential transfer device 10 and to quickly transfer the materials 5 to the shield machine 6.

  In the first embodiment, as described above, the empty carriage 35b is sent out from the circumferential conveyance device 10 at the mounting position P2 to the second passage 31b, and the loading carriage 35a is sent from the first passage 31a to the circumferential conveyance device 10. The connection transfer device 30 is configured as follows. Thereby, the materials 5 can be loaded onto the circumferential conveyance device 10 only by exchanging the empty carriage 35b and the loading carriage 35a. Then, since the replacement of the carriages can be performed from the separate passages by the first passage 31a and the second passage 31b, the time required for loading the materials 5 onto the circumferential conveyance device 10 can be further shortened. In addition, since the loading time is shortened, a time margin occurs for the conveyance of the circumferential conveyance device 10, and the difference between the timing at which the equipment 5 is required and the timing at which the equipment 5 arrives. It becomes possible to respond flexibly.

  In the first embodiment, as described above, each operation information 41 of the shield machine 6, the circumferential conveyance device 10, and the equipment storage unit 20 is collected, and the equipment storage is performed according to the operation of the shield machine 6. While supplying the equipment 5 from the unit 20, the transport request of the equipment 5 to the equipment storage unit 20 is output to the ground supply facility 70 so that the equipment 5 of the specified quantity is secured in the equipment storage unit 20. A physical distribution management unit 40 configured as described above is provided. As shown in FIG. 9, when a plurality of shield machines 6 excavate the outer shell tunnel 2 simultaneously in parallel, since the respective excavating conditions do not necessarily coincide, the supply and demand management of the materials 5 becomes difficult . Therefore, according to the above-described physical distribution management unit 40, the demand and supply of the materials 5 in the transport system 100 can be integratedly managed based on the respective operation information 41. As a result, the conveyance operation of the equipment storage unit 20, the circumferential conveyance device 10, and the connection conveyance device 30 according to the timing when the equipment 5 is needed by the shield machine 6 is realized, and the timing when the equipment 5 is needed The timing at which the equipment 5 arrives from the ground supply facility 70 can be adjusted so that the stock amount that can cope with the situation is always secured.

Second Embodiment
Next, a second embodiment of the present invention will be described with reference to FIG. In this second embodiment, unlike the first embodiment in which the three-dimensional storage 21 is provided in the material and equipment storage unit 20, an example will be described in which the three-dimensional storage 21 is not provided in the material and equipment storage unit 120. The same components as those in the first embodiment are denoted by the same reference numerals as in the first embodiment, and the description thereof is omitted.

  In the transport system 200 of the second embodiment shown in FIG. 10, the equipment storage unit 120 does not have the three-dimensional storage 21 and has a configuration in which the tunnel transport carts 61 are stored side by side. That is, the equipment storage unit 120 includes a standby conveyance path 121 capable of arranging and standing by a plurality of tunnel conveyance carts 61.

  Specifically, the transport route 60 includes the forward route 62 and the return route 63 that merge in the branch unit 64, and the first transport route 60a after the merge, and the standby transport route 121 is the forward route before the branch unit 64. Provided as part of 62. At the supply position P1, a gantry crane 122 is provided for transferring the material 5 to the traverser carriage 33 of the connecting and transporting apparatus 130.

  The equipment storage unit 120 sends the tunnel carriage 61 carrying the equipment 5 from the standby conveyance path 121 to the first transportation route 60 a. At the end of the first transport path 60a, the gantry crane 122 transfers the equipment 5 loaded on the tunnel carriage 61 to the empty carriage 35b disposed on the traverser carriage 33 at the supply position P1.

  In the connection conveyance device 130, the loading carriage 35a carrying the equipment 5 at the supply position P1 is loaded together with the carriage on the self-propelled conveyance device 12 at the loading position P2. The gantry crane 122 may carry the tunnel carrier 61 carrying the materials 5 onto the traverser carrier 33 as it is without carrying out transfer from the tunnel carrier 61 to the empty carrier 35b at the supply position P1.

  The empty tunnel carrier 61 turns back the first transport path 60 a, travels from the branch portion 64 to the return path 63, and returns to the ground supply facility 70.

  In the second embodiment, since the three-dimensional storage 21 is not provided, a transported object such as a shield machine 6 or a component of the shield machine 6 can also be transported by the same transport path 60 as the material 5. Also in the second embodiment, as in the first embodiment, the transport route 60 may be provided with the second transport route 60b.

  In addition, the equipment storage unit 120 may not be configured to store the tunnel transport carts 61 side by side. For example, the equipment storage unit 120 may be one or a plurality of conveyor lines extending toward the supply position P1. In this case, for example, the gantry crane 122 is disposed at the inlet and the outlet of the conveyor line, and the gantry crane 122 at the inlet side transfers the materials 5 of the tunnel carriage 61 to the inlet of the conveyor line, and the gantry crane at the outlet side. The equipments 122 are transferred to the empty carriage 35 b disposed on the traverser carriage 33 at the supply position P 1. Thus, the equipment 5 can be stored on the conveyor line.

  In the configuration example shown in FIG. 10, the form of the connection passage 31 of the connection conveyance device 130 is different from that of the first embodiment. In the configuration example of FIG. 10, a rectangular annular circulation passage is configured by the four rectangular passage portions 132a to 132d. The first passage 31a includes a passage portion 132a going from the supply position P1 to the back side, a passage portion 132b in the horizontal direction orthogonal to the passage portion 132a, and a passage portion 132c going from the passage portion 132b to the mounting position P2. The second passage 31 b is constituted by a passage portion 132 d which directly connects the mounting position P 2 and the supply position P 1. In this case, compared to the first embodiment shown in FIG. 7, there is no common portion (the passage portion 32c and a portion of the passage portion 32e in FIG. 7) of the first passage 31a and the second passage 31b. The first passage 31a and the second passage 31b are configured as passages independent of each other except for the position P1 and the mounting position P2. Therefore, the empty carriage 35b and the loading carriage 35a can be replaced more quickly.

  The remaining structure of the second embodiment is similar to that of the aforementioned first embodiment.

(Effect of the second embodiment)
In the second embodiment, the following effects can be obtained.

  In the second embodiment, similarly to the first embodiment, by providing the equipment storage unit 20 and the connection conveyance device 130, the material is transported from the ground supply facility 70 through the transportation route 60 in the underground structure 1. The materials and equipment 5 can be temporarily stored in the material and equipment storage unit 20, and can be supplied at timing according to the timing when the materials and equipment 5 are needed. As a result, the materials 5 can be supplied in a timely manner without delay over the entire supply route of the materials 5 from the ground to the shield machine 6 via the circumferential conveyance device 10.

  The other effects of the second embodiment are the same as those of the second embodiment.

[Modification]

The number of layers of the storage unit 21 a in the three-dimensional storage 21 may be two or four or more. The number of rows of storage units 21 a in the three-dimensional storage 21 may be one row, two rows, or four or more rows. The number of layers and the number of columns of the storage unit 21a in the three-dimensional storage 21 can be arbitrarily set in accordance with the number of types of materials 5 and the number of materials 5 to be stored.

  In the first embodiment described above, although the example in which the three-dimensional storage 21 of the post-in-first-out method is provided including the storage unit 21a having the transport conveyor 21b for forward feeding toward the supply position P1 is shown, Is not limited to this. The three-dimensional storage 21 may be, for example, a stacker crane type three-dimensional storage. In the stacker crane system, a shelf is provided along the runway on which a storage portion for storing the equipment 5 is formed on one side or both sides of the crane apparatus movable and capable of moving up and down the runway toward the supply position P1. . The crane apparatus can hold the equipment 5 and can move the equipment 5 to any position on the shelf. In the stacker crane method, unlike the post-in-first-out method, the crane apparatus can store the equipment 5 at an arbitrary position on the shelf and carry out the equipment 5 at any position. The equipment 5 can be easily classified and stored.

  Also, as a configuration example in the case where the three-dimensional storage 21 is not provided in the material and equipment storage unit 20, a gantry crane 24 that can move across the entire material and equipment storage unit 20 is provided. May be stored side by side. In this case, the equipment 5 transported from the transport path 60 is transferred to the equipment storage unit 20 by the gantry crane 24, and the equipment 5 to be supplied next is transferred to the supply position P1 by the gantry crane 24.
