[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 bolt 4, various tunnel construction materials such as mortar for fixing the rock bolt (not shown), sprayed concrete, quick-setting material, waterproof sheet, 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 machine 6 to manage the inventory of tunnel construction materials. The surveying machine 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 machine 6 and the processing device 10 are connected so as to be able to communicate data 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 Figure 2, the processing unit 10 includes a processing unit 11, a storage unit 12 (storage means), a communication unit 13, and a display unit 15. The surveying instrument 6 is connected to the communication unit 13 via a LAN 7. The processing unit 11 is composed of a CPU and has functions such as an acquisition means 11b for obtaining excavation progress information, a calculation means 11c for materials used, and an update means 11d for updating estimated inventory quantities.

[0015] The memory unit 12 stores geological distribution information 12a, required materials information 12b, estimated inventory information 12c, and an inventory management support program 14. As shown in Figure 3, the geological distribution information 12a is information (Figure 1) regarding the distribution of geological formations 2a to 2e along the planned construction line 1s of the tunnel 1 in the natural ground 2, and includes data on the distance from the starting tunnel entrance 1a or the type of rock mass for each section a to e (Figure 1), the geological grade such as the hardness of the natural ground, and other characteristics of the natural ground. The geological distribution information 12a is obtained through prior boring surveys, etc. As shown in Figure 1, sections a to e are preferably set for each geological formation 2a to 2e that the planned tunnel construction line 1s crosses.

[0016] As shown in Figure 4, the required materials information 12b is information on the materials (number of rock bolts, etc.) necessary for tunnel construction according to the geological distribution and design support pattern. The design support pattern correlates with the geological grade. As shown in the same figure, the required materials information 12b may be a combination of geological distribution information 12a (Figure 3). That is, the required materials information 12b may be a database of the types and quantities of materials required per unit excavation distance for each section a to e (Figure 1) from the starting portal 1a of the tunnel 1 subject to inventory management support. The required materials information 12b may also contain the geological distribution information 12a. Geological distribution information 12a and required materials information 12b are acquired prior to the construction or inventory management support of tunnel 1 and stored in the memory unit 12.

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

[0018] As shown in Figure 2, the inventory management support program 14 includes a drilling progress information acquisition program 14b, a material usage calculation program 14c, an estimated inventory quantity update program 14d, and the like. The excavation progress information acquisition program 14b is a program that causes the computer to execute the process of acquiring excavation progress information for tunnel 1. The material usage calculation program 14c is a program that causes a computer to perform the 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 perform the process of updating the estimated inventory quantity of tunnel construction materials.

[0019] <Methods for supporting inventory management of tunnel construction materials> As shown in the flowchart in Figure 6, the inventory management support system 5 for tunnel construction materials is performed as follows. The processing unit 11 of the processing unit 10 communicates with the surveying instrument 6 upon activation of the inventory management support program 14 (step 101).

[0020] During the construction of tunnel 1, the position of the inside of tunnel 1 and, consequently, the tunnel face 1e is measured using a surveying instrument 6. The survey data is transmitted from the surveying instrument 6 to the processing unit 10. The transmission timing may be each time a survey is performed, at regular intervals, after each section of excavation is completed, or at the end of the day's excavation work.

[0021] The processing unit 10 receives the survey data ("yes" in step 101). The method for inputting survey data into the processing unit 10 is not limited to network communication; an operator may also manually input the survey data from the surveying instrument 6 into the processing unit 10. Alternatively, the survey data from the surveying instrument 6 may be stored on a portable storage medium, and the portable storage medium may be connected to the processing unit 10 to read the stored data.

[0022] The processing unit 11, acting as the means for acquiring excavation progress information 11b, acquires excavation progress information, indicating how far tunnel 1 has been excavated, from the survey data using the excavation progress information acquisition processing program 14b (step 102).

[0023] Next, the processing unit 11, acting as the material usage calculation means 11c, uses the material usage calculation program 14c to calculate the types and quantities of materials used since the last update of the estimated inventory quantity, based on the geological distribution information 12a and required material information 12b stored in the storage unit 12, and the excavation progress information (step 103).

[0024] Furthermore, the processing unit 11, acting as the estimated inventory quantity update means 11d, updates the estimated inventory quantity of the relevant material using the estimated inventory quantity update processing program 14c (step 104). Specifically, for each material, the calculated usage quantity is subtracted from the estimated inventory quantity at the time of 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 accordance with the display command (step 110) (step 111). The display may be done via a web browser. Alternatively, the information may be printed out as a report. This allows the person in charge of inventory management to understand the inventory status of each material. This eliminates the need to frequently check the inventory status and reduces the burden of inventory management.

[0026] Next, other embodiments of the present invention will be described. In the following embodiments, components that overlap with those described above will be denoted by the same reference numerals in the drawings and their descriptions will be omitted as appropriate. <Second Embodiment (Figures 7-8)> As shown in Figure 7, in addition to geological distribution information 12a and required materials information 12b, construction schedule information 12f is stored in the storage unit 12 of the processing unit 10 of the inventory management support system 5B in the second embodiment as further pre-acquired information. As shown in Figure 8, the construction schedule information 12f includes information such as the date or the number of days elapsed since the start of construction and the planned excavation distance. The processing unit 10 may extract the construction schedule information 12f from the input data of the construction management software stored in the processing unit 10. Preferably, the construction schedule information 12f can be modified in accordance with the actual progress of the construction of tunnel 1.

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

[0028] <Third Embodiment (Figures 9-10)> As shown in Figure 9, the inventory management support system 5C according to the third embodiment can communicate with the management system 8, which stores the surveying data of the surveying instrument 6. The management system 8 is configured by a computer separate from the processing unit 10. The 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. The construction schedule information 12f may also be stored in the storage unit of the management system 8, and the inventory management support system 5C may receive the construction schedule information 12f from the management system 8.

[0029] As shown in the flowchart of Figure 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). If survey data is received, that survey data is used as excavation progress information indicating how far tunnel 1 has been excavated (step 102). If survey data is not received, the construction schedule information 12f is read (step 101b), and the excavation progress information is obtained from that construction schedule information 12f (step 102). If the construction schedule information 12f is not stored or is not available as excavation progress information ("no" in step 101b), the system checks whether excavation progress information has been manually entered (step 101c). If there is manual input such as excavation distance data from the starting tunnel entrance 1a, that is adopted as excavation progress information (step 102). Furthermore, even if survey data is received or valid construction schedule information 12f is available ("yes" in step 101a or 101b), it is also possible to check whether manual input of excavation progress information has been made, and if manual input has been made, that manual input information may be given priority as the excavation progress information.

[0030] Using the acquired excavation progress information, the estimated inventory quantity is updated by steps 103 to 104, similar to those in the first embodiment (Figure 6), and then the alarm processing program 14f determines whether an alarm is necessary (step 105). Specifically, it is checked whether the updated estimated inventory quantity is less than the quantity required for construction work in the near future for each tunnel construction material. The quantity required for construction work in the near future is preferably calculated using construction schedule information 12f (see Figure 8). Whether or not a project is in the near future is determined, for example, by whether or not it is within the number of days required for delivery after ordering the corresponding tunnel construction material.

[0031] For each tunnel construction material, an alarm is issued if the estimated inventory quantity falls below the quantity required for the upcoming construction process (step 106). The alarm may be displayed on the display unit 15 or emitted as an audible alert. In conjunction with, or instead of, the alarm in step 106, the processing unit 10 may automatically order the required quantity of the tunnel construction materials.

[0032] The present invention is not limited to the embodiments described above, and various modifications can be made without departing from its spirit. For example, when a manager actually checks the inventory status, the estimated inventory quantity in the memory unit 12 may be corrected to reflect the actual quantity checked. The materials for tunnel construction to be managed in inventory may include auxiliary construction materials such as pre-supported steel pipes and grouting materials. In the second embodiment (Figures 7-8), as in the third embodiment (Figures 9-10), the construction schedule information 12f may be used to determine whether the inventory quantity of each tunnel construction material is below the quantity required for the upcoming construction work. If it is below the required quantity, an alarm may be issued or an automatic order may be placed. [Industrial applicability]
