[0024] First Embodiment 1. Configuration of daily report creation system 100 A daily report creation system 100 according to a first embodiment of the present disclosure will be described below with reference to Figures 1 to 18. The daily report creation system 100 according to the first embodiment shown in Figure 1 is an example of the daily report creation system according to the present disclosure.

[0025] The daily report creation system 100 is a system that creates a daily report of a construction method for reinforcing the natural ground 102 by injecting injection material into the natural ground 102 around a tunnel 101 (hereinafter also referred to as a natural ground reinforcement construction method). As shown in FIG. 1, the daily report creation system 100 includes an injection machine 10, a portable terminal 20, and a daily report creation device 30. The injection machine 10 is a device that injects injection material into injection holes 103 in the natural ground 102 of the tunnel 101. The portable terminal 20 acquires data related to injection for each injection hole 103 (hereinafter also referred to as injection data) from the injection machine 10. The injection data is used to create a daily report for the natural ground reinforcement construction method. The daily report creation device 30 is a device that acquires the injection data from the portable terminal 20 and creates a daily report (document) for the natural ground reinforcement construction method.

[0026] 2. Overview of ground reinforcement methods In the ground reinforcement method of the first embodiment, as shown in Fig. 1, a plurality of steel pipes (long steel pipes) 105 are driven into a face 104 of an unexcavated front ground 102 around a tunnel 101, and the steel pipes 105 are arranged in injection holes 103. Then, an injection material (ground improvement material) is injected into the steel pipes 105, and the injection material is allowed to penetrate into cracks in the surrounding ground from discharge holes 106 provided on the outer periphery of the steel pipes 105, thereby reinforcing the ground.

[0027] The internal space of the steel pipe 105 is divided into a plurality of injection zones (three injection zones 105A-105C in FIG. 1) in the longitudinal direction. The injection material is injected into each of the injection zones 105A-105C, and the injection material is discharged from each of the injection zones 105A-105C through the discharge hole 106. For example, the portions of the injection hole 103 that correspond to (overlap in the longitudinal direction) the injection zones 105A-105C, respectively, are called the red hole, the yellow hole, and the blue hole.

[0028] In this ground reinforcement method, for example, a urethane-based foaming resin such as silica resin is used as the injection material. In this case, two types of liquids A and B are mixed and injected into the ground 102 while foaming, and then hardened, thereby improving the ground 102 around the tunnel 101. Furthermore, multiple steel pipes 105 are driven into the ground 102 around the tunnel 101, extending diagonally and linearly with respect to the tunnel axis, and are arranged at intervals around the circumferential direction of the arch portion 101A of the tunnel 101, as shown in FIG. 2. For construction management purposes, the multiple steel pipes 105 are assigned hole numbers (e.g., hole numbers 1-21 in FIG. 2) in the order of their arrangement along the arch portion 101A. Furthermore, in this ground reinforcement method, for example, a steel pipe 105 is driven into every other hole, and after injection of injection material into these steel pipes 105, another steel pipe 105 is driven in between, and injection of injection material into these steel pipes 105 is then performed. The plurality of steel pipes 105 are respectively referred to as odd-numbered holes (for example, steel pipes 105 with leading hole numbers) and even-numbered holes (for example, steel pipes 105 with trailing hole numbers).

[0041] 6. Step of acquiring injection data using the portable terminal 20 The process of acquiring injection data by the portable terminal 20 will be described with reference to Figs. 4 to 13. Fig. 4 is a flowchart illustrating the flow of the process of acquiring injection data executed by the portable terminal 20. Control in the flowchart shown in Fig. 4 is executed by the control unit 21 of the portable terminal 20.

[0042] An application program (daily injection report management app) for creating daily injection reports is installed on the portable terminal 20. The daily injection report management app is a program that can execute the control described below (at least steps S2-S6 in FIG. 4). When the daily injection report management app is launched on the portable terminal 20, the top page of the app as shown in FIG. 5 is displayed on the display unit 14. Pressing the "Register construction information" button on the top page takes you to the construction information registration page shown in FIG. 6. Next, enter information such as the name of the project, the injection machine model, the chemical solution used, and the construction method. Once you have completed entering the information, press the "Register" button to register the conditions (step S1 in FIG. 4).

[0043] Once you have finished registering the conditions, you will return to the top page, and then press the "Injection Record" button on the top page as shown in Figure 5. When you press the "Injection Record" button, a list of registered construction projects (construction names) will be displayed as shown in Figure 7, so select the construction project (construction name) for which you want to create a daily report. When a construction project is selected, the registered data for each construction location will be displayed, so select the data item (construction location) for which you want to read the image.

[0044] For example, as shown in Figure 8, details of the construction location are displayed. Details of the construction location can be selected between odd-numbered holes and even-numbered holes. When an odd-numbered hole is selected, detailed information for each injection hole 103 included in the odd-numbered holes is displayed. When an even-numbered hole is selected, detailed information for each injection hole 103 included in the even-numbered holes is displayed. Pressing the pencil button B1 in the upper right corner of the display unit 14 will take you to the injection amount registration screen shown in Figure 9. The injection amount registration screen displays the registration status of various data for each injection hole 103. Pressing the camera button B2 in the upper right corner of the display unit 14 will switch to reading mode as shown in Figure 11.

[0045] The portable terminal 20 is switched to the reading mode, and the injection machine 10 is operated to display on the display unit 14 a data display screen of the injection record for creating a daily report as shown in FIG. 10. On the data display screen, for example, for each injection hole 103 (hole number), identification information for identifying the injection hole 103, the total injection amount, the injection start time, and the injection end time are displayed in positions corresponding to the display position of the display name. Specifically, the identification information of the injection hole 103 is displayed in the item name columns for the red hole, yellow hole, and blue hole described below. For example, "Red Hole No. 1" corresponds to the red hole of the injection hole 103 with hole number "1." Also, specifically, the value of the total injection amount is displayed adjacent to (below adjacent to) the words "Total Injection Amount," the injection start time is displayed adjacent to (below adjacent to) the words "Start Time," and the injection end time is displayed adjacent to (below adjacent to) the words "End Time."

[0046] Furthermore, the data display screen displays values ​​such as flow rate, various injection pressures (Liquid A pressure, Liquid B pressure, absolute stop pressure, stop pressure, initial pressure, final pressure, etc.), various injection volumes (injection volume, set injection volume, cumulative injection volume, etc.) for each part (red hole, yellow hole, blue hole) that makes up injection hole 103 (for each hole number) in positions corresponding to the display positions of the display names. Specifically, the numerical values ​​corresponding to each item are displayed in a matrix format with red holes, yellow holes, and blue holes as columns and various injection pressures and various injection volumes as rows. For example, the flow rate of red hole No. 1 is displayed as a numerical value in the columns (second from the left and second from the top) corresponding to the item names "Red Hole No. 1" and "Flow Rate."

[0047] Imaging in the reading mode on portable terminal 20 (step S2) is performed, for example, by pressing button B3 located at the bottom center of display unit 14. After capturing an image using imaging unit 26, portable terminal 20 uses its OCR function to extract letters and numbers (the letters and numbers enclosed in a thin-lined rectangle shown in FIG. 12) from the captured image (see FIG. 12) on the data display screen displayed on display unit 14 of injection machine 10 (step S3). From the letters and numbers extracted using the OCR function, the following data are further extracted as read data (injection data): identification information identifying injection hole 103, total injection volume, injection start time, injection end time, flow rate for each of the components (red hole, yellow hole, blue hole) that make up injection hole 103, various injection pressures (fluid A pressure, fluid B pressure, absolute stop pressure, stop pressure, initial pressure, final pressure, etc.), various injection volumes (injection volume, set injection volume, cumulative injection volume, etc.). Each item is associated with the corresponding numerical value and extracted. For example, the character data "flow speed of red hole" and the numerical value of the flow speed of the red hole are associated and extracted.

[0048] Control unit 21 of portable terminal 20 corresponds to an example of the “extraction unit” of the present disclosure, and functions to extract injection data from the image of display unit 14 of injection machine 10 captured by imaging unit 26.

[0049] The display screen of the display unit 14 of the injection machine 10 is preferably configured to display white letters and numbers on a black background, which is expected to improve the accuracy of analysis (extraction accuracy) of letters and numbers by the control unit 21 of the portable terminal 20.

[0050] After the read data is extracted, the numerical values ​​within the range enclosed by the thin-lined rectangle on the injection amount registration screen shown in FIG. 13 are displayed as authentication data (read data) (step S4). The user can check the authentication data and manually correct any deficiencies by operating the operation unit 23 (step S5). Pressing the "Register" button located at the bottom center of the display unit 14 shown in FIG. 13 (step S6) confirms the numerical values, and various data (injection data) are added to the screen displaying the details of the construction location shown in FIG. 8. The injection data includes, for example, the total injection amount (total injection amount), injection start time, injection end time, and injection time (calculated from the injection start time and injection end time) for each identification information (hole number) of the injection hole 103, as well as the injection amount and pressure range (range from initial pressure to final pressure) for each part (red hole, yellow hole, blue hole) that makes up the injection hole 103. By repeating the above steps (steps S2-S6), injection data is registered for all injection holes 103 at all construction locations. Specifically, each item and the numerical value indicated by that item are associated with each other and stored in the storage unit 22. For example, the text data of "flow speed of red hole" and the numerical value of the flow speed of the red hole are associated with each other and stored in the storage unit 22.

[0051] After injection into all injection holes 103 at all construction positions is complete (step S7) and all injection data has been registered, the user returns to the top page of the app shown in Figure 5 and presses the "File Output" button (step S8). This displays the file output page shown in Figure 14. The user selects the name of the construction project for which a daily report is to be created and presses the "File Output" button. The injection data for each injection hole 103 at all construction positions is saved (stored) in memory unit 22 in a specific folder (storage area) within mobile terminal 20 (step S9). The injection data can be saved in a file format such as CSV or XLSM.

[0052] The storage unit 22 of the portable terminal 20 corresponds to an example of the "storage unit" of the present disclosure, and functions to store the extracted injection data.

[0053] 7. Daily report creation process using daily report creation device 30 The daily report creation process by the daily report creation device 30 will be described with reference to Figures 15 to 19. Figure 15 is a flowchart illustrating the flow of the daily report creation process executed by the daily report creation device 30.

[0054] The injection data stored in the portable terminal 20 (injection data for each injection hole 103 at all construction positions that can be identified by the construction name) is transferred to the daily report creation device 30 either online (via a communication interface) or offline (via a recording medium) (step S11 in FIG. 15). The daily report creation device 30 may also acquire the injection data by downloading it from the portable terminal 20, which has been uploaded to a server (such as a cloud server).

[0055] A software program (injection daily report creation tool) for creating a daily injection report is installed in the daily report creation device 30. When the daily injection report creation tool is launched on the daily report creation device 30, a software page such as that shown in FIG. 16 is displayed on the display unit 34. When the "Create Daily Report" button is pressed (step S12), a "Browse Folder" command such as that shown in FIG. 17 appears, and the user selects the injection data transferred from the mobile terminal 20 (injection data for each injection hole 103 at all construction positions that can be identified by the construction name) and presses the "OK" button with the data selected. Then, an injection daily report (daily report for the ground reinforcement method) such as that shown in FIGS. 18 and 19 is created within the daily report creation tool (step S13). This daily report can be saved (stored) in the memory unit 32 in a specific file format (CSV format, XLSM format, etc.) and can also be printed from the output unit 35.

[0056] For example, the daily injection report shown in Figure 18 lists values ​​such as the injection amount and injection pressure for each injection hole (each hole number) - red hole, yellow hole, and blue hole, injection time, total injection amount, etc. Also, the daily injection report shown in Figure 19 lists a graph showing the injection amount for each injection hole (each hole number) - red hole, yellow hole, and blue hole.

[0057] 8. Effects of the First Embodiment The portable terminal 20 of the first embodiment is used in a construction method for reinforcing the natural ground 102 by using an injection machine 10 to inject injection material into the natural ground 102 around a tunnel 101. The portable terminal 20 includes an imaging unit 26 that captures an image of the display unit 14 of the injection machine 10, which displays data related to injection for each injection hole 103 into which the injection material is injected, a control unit (extraction unit) 21 that extracts data (injection data) from the image of the display unit 14 captured by the imaging unit 26, and a memory unit 22 that stores the extracted data.

[0058] According to this configuration, the imaging unit 26 of the portable terminal 20 is used to capture an image of the display unit 14 of the injection machine 10, which displays injection data (data related to injection for each injection hole 103 into which the injection material used in the natural ground reinforcement method for the tunnel 101 is injected), and the control unit 21 can extract the injection data from the captured image. The injection data extracted by the control unit 21 can then be stored in the memory unit 22. Therefore, by utilizing the imaging by the portable terminal 20, the injection data related to injection for each injection hole 103 used in the natural ground reinforcement method for the tunnel 101 can be obtained regardless of the communication environment. Furthermore, there is no need to provide a separate communication network environment (such as an internet environment), which simplifies the equipment used.

[0059] The data acquired by the mobile terminal 20 of the first embodiment is used to create a daily report on the natural ground reinforcement method. According to this configuration, the data for creating a daily report on the natural ground reinforcement method can be acquired regardless of the communication environment.

[0060] The data acquired by portable terminal 20 of the first embodiment includes identification information for identifying injection hole 103, the injection start time, the injection end time, the initial pressure, the final pressure, and the injection amount. With this configuration, it is possible to acquire the injection start time, the injection end time, the initial pressure, the final pressure, and the injection amount for each injection hole 103 identified by the identification information.

[0061] Portable terminal 20 of the first embodiment can be switched between a state in which it is used while connected to a communications network and a state in which it is used without being connected to a communications network. With this configuration, even portable terminal 20 that is normally used while connected to a communications network can obtain data related to injection hole 103 in an environment in which it cannot be connected to a communications network.

[0062] The daily report creation system 100 of the first embodiment creates a daily report for a construction method of reinforcing natural ground 102 by injecting a grouting material into the natural ground 102 around a tunnel 101. The daily report creation system 100 includes an injection machine 10 that injects grouting material, a portable terminal 20 that acquires data (injection data) related to the injection of each injection hole 103 into which the grouting material is injected from the injection machine 10, and a daily report creation device 30 that acquires the injection data from the portable terminal 20 and creates a daily report. The injection machine 10 has a display unit 14 on which the injection data is displayed. The portable terminal 20 has an imaging unit 26 that captures an image of the display unit 14, a control unit 21 that extracts the injection data from an image of the display unit 14 captured by the imaging unit 26, and a storage unit 22 that stores the injection data extracted by the control unit 21. With this configuration, the daily report creation device 30 can create a daily report for the natural ground reinforcement construction method for the tunnel 101 by acquiring the injection data from the portable terminal 20.

[0063] The construction method of the first embodiment is a construction method in which an injection machine 10 injects injection material into the natural ground 102 around a tunnel 101 to reinforce the natural ground 102. In this construction method, the imaging unit 26 of the portable terminal 20 captures an image of the display unit 14 of the injection machine 10, which displays data related to injection (injection data) for each injection hole 103 into which the injection material is injected, and the injection data is extracted from the image of the display unit 14 captured by the imaging unit 26, and a daily report is created from the extracted injection data. With this configuration, a daily report of the natural ground reinforcement method for the tunnel 101 can be created from the portable terminal 20 using the injection data.

[0064] The program of the first embodiment is a program installed in a portable terminal 20 used in a construction method for reinforcing the natural ground 102 around a tunnel 101 by injecting a grouting material into the natural ground 102 using an injection machine 10. This program causes a computer (control unit 21) of the portable terminal 20 to use an imaging unit 26 to capture an image of the display unit 14 of the injection machine 10, which displays data (injection data) related to injection of the grouting material into each injection hole 103 into which the grouting material is injected, extract the injection data from the image of the display unit 14 captured by the imaging unit 26, and store the extracted injection data in a memory unit 22. According to this configuration, by utilizing the imaging by the portable terminal 20, it is possible to obtain the injection data related to injection into each injection hole 103 used in the natural ground reinforcement construction method for the tunnel 101 regardless of the communication environment.

[0065] <Other embodiments> The present invention is not limited to the embodiments described above and illustrated in the drawings, and the following embodiments are also included within the technical scope of the present invention. Furthermore, the various features of the above-mentioned embodiments and the embodiments to be described later may be combined in any manner as long as they are not contradictory.

[0066] In the first embodiment, when the portable terminal 20 extracts injection data from the captured image, if each item (character data) and the numerical value indicated by that item are in a corresponding positional relationship (e.g., adjacent positional relationship), they are extracted in correspondence with each other. However, for example, a numerical value at a predetermined position in the captured image, based on a predetermined position (e.g., a frame line), may be extracted as a numerical value indicating the predetermined item. For example, a numerical value in the upper right column of the captured image may be extracted as a numerical value of the flow rate of the blue hole. [Explanation of symbols]
