Embodiments for Carrying Out the Invention

[0011] Hereinafter, embodiments of the present invention will be described with reference to the drawings. <First Embodiment (FIGS. 1 to 6)> As shown in FIG. 1, a mountain tunnel 1 is being excavated in the natural ground 2. In the construction of the mountain tunnel 1, in addition to the arch support 3 and the rock bolts 4, various tunnel construction materials such as mortar for fixing rock bolts (not shown), sprayed concrete, quick-setting materials, waterproof sheets, concrete for lining, reinforcing bars for lining, and concrete for invert are required. The types and quantities of tunnel construction materials required in terms of design per unit excavation distance of the tunnel are determined according to the geology 2a to 2e of the natural ground 2. In the case of hard and non-collapsible geology, the number of rock bolts used can be small. In the case of soft and collapsible geology, the number of rock bolts used increases.

[0012] <Inventory Management Support System for Tunnel Construction Materials> The inventory management support system 5 of the present embodiment uses the tunnel excavation status measured by the surveying instrument 6 to manage the inventory of tunnel construction materials. The surveying instrument 6 is permanently installed in the tunnel 1 under construction in order to measure the excavation direction, shape, tunnel distance (TD), etc. of the tunnel.

[0013] The inventory management support system 5 includes a processing device 10. The surveying instrument 6 and the processing device 10 are connected so as to be capable of data communication by a wired or wireless local area network (LAN) 7. The processing device 10 is composed of a personal computer (PC), a smartphone, a tablet, or other computers, and may be composed of cloud computing.

[0014] As shown in FIG. 2, the processing device 10 includes a processing unit 11, a storage unit 12 (storage means), a communication unit 13, and a display unit 15. A surveying instrument 6 is connected to the communication unit 13 via a LAN 7. The processing unit 11 is composed of a CPU or the like and has functions as an acquisition means 11b for tunneling progress information, a calculation means 11c for used materials, an update means 11d for estimated inventory quantity, and the like.

[0015] The storage unit 12 stores geological distribution information 12a, necessary material information 12b, estimated inventory information 12c, and an inventory management support program 14. As shown in FIG. 3, the geological distribution information 12a is information regarding the distribution status (FIG. 1) of the geology 2a to 2e on the construction planned line 1s of the tunnel 1 in the natural ground 2, including the type of bedrock, the geological grade such as the hardness and softness of the natural ground, and other property data of the natural ground for each distance from the starting shaft 1a or each section a to e (FIG. 1). The geological distribution information 12a is acquired by a prior boring survey or the like. As shown in FIG. 1, the sections a to e are preferably set for each geology 2a to 2e crossed by the tunnel construction planned line 1s.

[0016] As shown in FIG. 4, the necessary material information 12b is information on the materials (such as the number of rock bolts) required for tunnel construction according to the geological distribution and the design support pattern. The design support pattern is correlated with the geological grade. As shown in the figure, the necessary material information 12b may be a combination of the geological distribution information 12a (FIG. 3). That is, the necessary material information 12b may be a database of the types and quantities of necessary materials per unit tunneling distance for each distance from the starting shaft 1a or each section a to e (FIG. 1) of the tunnel 1 for which the inventory management support is targeted. The necessary material information 12b may include the geological distribution information 12a. The geological distribution information 12a and the necessary material information 12b are acquired prior to the construction of the tunnel 1 or the inventory management support and stored in the storage unit 12.

[0017] As shown in FIG. 5, the estimated inventory information 12c is data on the current estimated inventory quantity for each type (product name) of tunnel construction materials, and is overwritten and updated as needed by the management process of the system 5.

[0018] As shown in FIG. 2, the inventory management support program 14 includes a tunneling progress information acquisition processing program 14b, a used materials calculation program 14c, an estimated inventory quantity update processing program 14d, and the like. The tunneling progress information acquisition processing program 14b is a program that causes a computer to execute a process of acquiring the tunneling progress information of the tunnel 1. The used materials calculation program 14c is a program that causes a computer to execute a process of calculating the type and quantity of tunnel construction materials used. The estimated inventory quantity update processing program 14d is a program that causes a computer to execute a process of updating the estimated inventory quantity of tunnel construction materials.

[0019] <Inventory Management Support Method for Tunnel Construction Materials> As shown in the flowchart of FIG. 6, the inventory management support for tunnel construction materials by the inventory management support system 5 is performed as follows. The processing unit 11 of the processing device 10 communicates with the total station 6 by starting the inventory management support program 14 (step 101).

[0020] During the construction of the tunnel 1, the total station 6 measures the position of the inside of the tunnel 1 and thus the face 1e. The measurement data is transmitted from the total station 6 to the processing device 10. The transmission timing may be each time a measurement is made, at regular intervals, each time the excavation work for one cross-section is completed, or when the excavation work for one day is completed.

[0021] The processing device 10 receives the measurement data (the "yes" in step 101). As a method of inputting measurement data into the processing device 10, not limited to network communication, an operator may read the measurement data of the measuring instrument 6 and manually input it into the processing device 10. The measurement data of the measuring instrument 6 may be stored in a portable storage medium, and the portable storage medium may be connected to the processing device 10 to read the stored data.

[0022] The processing unit 11 as the tunneling progress information acquisition means 11b acquires tunneling progress information on how far the tunnel 1 has advanced from the measurement data by the tunneling progress information acquisition processing program 14b (step 102).

[0023] Subsequently, the processing unit 11 as the used material calculation means 11c calculates the types and usage quantities of the materials used after the update of the previous estimated inventory quantity based on the geological distribution information 12a and the required material information 12b stored in the storage unit 12 and the tunneling progress information by the used material calculation program 14c (step 103).

[0024] Furthermore, the processing unit 11 as the estimated inventory quantity update means 11d updates the estimated inventory quantity of the corresponding material by the estimated inventory quantity update processing program 14c (step 104). Specifically, for each material, the usage quantity calculated value is subtracted from the estimated inventory quantity at the previous update, and the estimated inventory information 12c is overwritten with the subtracted value.

[0025] The estimated inventory quantity for each material calculated in this way is displayed on the display unit 15 in response to a display command (step 110) (step 111). The display may be made by a web browser. Instead of the display, it may be printed out as a form. Thereby, the person in charge of inventory management can grasp the inventory status of each material. There is no need to frequently check the inventory status, and the burden of inventory management can be reduced.

[0026] Next, another embodiment of the present invention will be described. In the following embodiments, for configurations that overlap with the previously described embodiments, the same reference numerals are given in the drawings and the description will be omitted as appropriate. <Second Embodiment (Figs. 7 to 8)> As shown in FIG. 7, in addition to the geological distribution information 12a and the necessary material information 12b, the construction schedule information 12f is stored in the storage unit 12 of the processing device 10 of the inventory management support system 5B in the second embodiment as further pre-acquired information. As shown in FIG. 8, the construction schedule information 12f includes information such as, for example, the date or the number of days elapsed since the start of construction, and the planned excavation distance. The processing device 10 may extract the construction schedule information 12f from the input data of the construction management software stored in the processing device 10. Preferably, the construction schedule information 12f can be corrected in accordance with the progress of the actual construction of the tunnel 1.

[0027] In the second embodiment, instead of the survey data of the first embodiment, the construction schedule information 12f is used as the excavation progress information indicating how far the tunnel 1 has been excavated. The processing unit 11 calculates the usage quantity for each tunnel construction material and, consequently, calculates the estimated inventory quantity based on the geological distribution information 12a, the necessary material information 12b, and the construction schedule information 12f and the calendar function.

[0028] <Third Embodiment (FIGS. 9 to 10)> As shown in FIG. 9, the inventory management support system 5C according to the third embodiment is communicable with the management system 8 in which the survey data of the surveying machine 6 is stored. The management system 8 is configured by a computer different from the processing device 10. An alarm processing program 14f is stored in the program area of the storage unit 12 of the inventory management support system 5C. The construction schedule information 12f is stored in the data area of the storage unit 12. Note that the construction schedule information 12f may be stored in the storage unit of the management system 8, or the inventory management support system 5C may receive the provision of the construction schedule information 12f from the management system 8.

[0029] As shown in the flowchart of FIG. 10, the processing unit 11 of the inventory management support system 5C attempts to communicate with the management system 8 and checks whether survey data has been received (step 101a). When the survey data is received, the survey data is used as the excavation progress information on how far the tunnel 1 has been excavated (step 102). When the survey data is not received, the construction schedule information 12f is read (step 101b), and the excavation progress information is obtained from the construction schedule information 12f (step 102). If the construction schedule information 12f is not stored or is not available as the excavation progress information ( "no" in step 101b), it is checked whether there is manual input of the excavation progress information (step 101c). When there is manual input such as the excavation distance data from the starting shaft 1a, it is adopted as the excavation progress information (step 102). Even when there is reception of the survey data or valid construction schedule information 12f ( "yes" in step 101a or 101b), it is also possible to further check whether there is manual input of the excavation progress information, and when there is manual input, the manual input information may be preferentially adopted as the excavation progress information.

[0030] Using the obtained excavation progress information, after updating the estimated inventory quantity by the same steps 103 to 104 as in the first embodiment (FIG. 6), it is determined whether an alarm is required by the alarm processing program 14f (step 105). Specifically, it is checked for each tunnel construction material whether the updated estimated inventory quantity is less than the quantity required in the upcoming construction. The quantity required in the upcoming construction is preferably calculated using the construction schedule information 12f (see FIG. 8). Whether it is an upcoming construction is determined, for example, by whether it is a construction within the delivery lead time after ordering the corresponding tunnel construction material.

[0031] For each tunnel construction material, when the estimated inventory quantity is less than the quantity required in the upcoming process, an alarm is output (step 106). As the alarm output, it may be displayed on the display unit 15 or announced by voice. In parallel with the alarm in step 106, or instead of the alarm, the processing device 10 may automatically place an order for the required quantity of the corresponding tunnel construction materials.

[0032] The present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the spirit thereof. For example, when the person in charge of management actually checks the inventory status, the estimated inventory quantity in the storage unit 12 may be corrected and input to the actual inspection quantity. As the tunnel construction materials to be inventory-managed, materials for auxiliary construction methods such as advance steel pipes and injection materials may be included. Also in the second embodiment (Figs. 7 to 8), as in the third embodiment (Figs. 9 to 10), it is determined using the construction schedule information 12f whether the inventory quantity of each tunnel construction material is less than the quantity required in the upcoming construction, and if so, an alarm may be output or an automatic order may be placed.
