Description

Technical Field

[0001] The present invention relates to an inventory management processing device for managing the inventory of various materials used in auxiliary methods for tunnel excavation.

Background Art

[0002] In the excavation construction of mountain tunnels, auxiliary methods such as the AGF (All Ground Fasten) method, the forepoling method, and the mirror bolt method are performed. For example, long steel pipes or hollow bolts are driven into the surrounding rock of the tunnel, and injection materials such as urethane-based foamed resin and mortar are injected into the surrounding rock. Thereby, the surrounding rock is stabilized (see Patent Document 1, etc.).

[0003] In this type of auxiliary method, the number of materials is large. For example, in the case of the AGF method, in addition to the tip pipe, intermediate pipe, and terminal pipe that make up the long steel pipe, a pilot bit, lost bit, coupling sleeve, tip rod, intermediate rod, etc. for driving the steel pipe into the surrounding rock are required. Furthermore, in addition to injection material raw materials such as silica resin, an injection hose, mixing pipe, valve, calking material, protective glasses, etc. for injection are also required. Not only materials such as steel pipes and injection materials that are placed and consumed by being driven into and injected into the surrounding rock, but also those that can be repeatedly used such as pilot bits and injection hoses are used in an environment where they are subjected to severe loads, resulting in severe wear, soiling, and deterioration. Therefore, most materials are consumables and need to be replenished at any time. Depending on the scale of the tunnel, the quantity of materials used becomes enormous.

Summary of the Invention

Problems to be Solved by the Invention

[0005] Each material is supplied from the material supplier to the tunnel construction site based on the shipping instructions of the construction manager according to the progress of the construction. The contractor uses the materials for construction. In order for the construction manager to accurately instruct the material supplier on the item, quantity, delivery date and time of the materials to be supplied, it is necessary to grasp the inventory of each material at the tunnel construction site. For this reason, the construction manager frequently counts the inventory of each material, for example, once a week to once every two weeks.

[0006] However, as described above, the number of material counts is large and the quantity is huge. Moreover, it is the contractor who performs the construction using the materials, and the contractor may independently change the storage location to make it easier to use the materials. Therefore, the construction manager often cannot fully grasp the usage status and inventory status, and inventory management is not easy. If the inventory of materials runs out even by one unit, it will cause problems in the construction work. Therefore, supply instructions are sometimes given in excess, and there are also cases where there is extra inventory. In view of such circumstances, an object of the present invention is to support the inventory management of materials used in tunnel auxiliary construction methods by a computer system.

Means for Solving the Problems

[0007] To solve the above problems, the method of the present invention is an inventory management method for a tunnel auxiliary construction method in which an injection material is injected from an injector into the surrounding ground of a tunnel under construction. The method is executed by an injector-side processing device that acquires injection information in the injector and an inventory management processing device that can communicate with the injector-side processing device and a user terminal. The inventory management processing device includes a storage unit that stores inventory information of materials used in the tunnel auxiliary construction method, and relationship information representing the relationship between the usage quantity of the above-mentioned materials and the injection information, and a processing unit. The following steps are executed in the processing unit: A step of receiving the injection information from the injector-side processing device; A step of updating the inventory information in the storage unit based on the received injection information and the relationship information; ​characterized by including By reflecting the quantity of materials used in the inventory information, the inventory status of the materials can be grasped, reducing the labor and effort of the construction manager for inventory management. Preferably, it includes a step of transmitting the inventory information in the storage unit to the utilization terminal under certain conditions. Examples of the certain conditions include when the inventory quantity of the material is below the reference quantity, when there is a request to view the inventory information from the utilization terminal of the construction manager or the material supplier, when information indicating that the auxiliary construction method for a 1-ton tunnel cross-section has been completed, when a fixed time has arrived, etc. Preferably, the processing unit further executes a step of monitoring whether the inventory quantity of each material in the inventory information is below the reference quantity, and when it is below, transmitting the inventory information to the utilization terminal used by the construction manager or the material supplier. Preferably, in the step of transmitting to the utilization terminal of the construction manager, a shipping instruction form in which the identification information of the material below the reference quantity and the predicted required shipping quantity are filled in is attached to the inventory information and transmitted.

[0008] The device of the present invention is an inventory management processing device for a tunnel auxiliary construction method that injects an injection material from an injector into the surrounding ground of a tunnel under construction, and includes a storage unit that stores the inventory information of the materials used in the tunnel auxiliary construction method and relationship information representing the relationship between the quantity of materials used and the injection information by the injector, and a processing unit, and the processing unit an injection information reception unit that receives the injection information from an injector-side processing device provided in the injector to acquire the injection information, an update unit that updates the inventory information in the storage unit based on the received injection information and the relationship information, characterized by including According to the device of the present invention, the general inventory status of the materials can be grasped, reducing the labor and effort of the construction manager for inventory management. Preferably, the processing unit includes a transmission processing unit that transmits the inventory information in the storage unit to the utilization terminal under certain conditions. Preferably, the transmission processing unit transmits the inventory information to the user terminals of the construction manager and the material supplier, respectively.

[0009] In the inventory management processing apparatus, the processing unit further includes a shipping information receiving unit that receives shipping information of materials from a user terminal, when there is a reception of the shipping information, it is preferable that the update unit updates the inventory information in the storage unit based on the shipping information. For example, when a material supplier ships materials and transmits (uploads) the shipping information from the user terminal of the material supplier to the inventory management processing apparatus, the inventory management processing apparatus reflects the shipping details in the inventory information.

[0010] In the inventory management processing apparatus, the processing unit further includes a correction receiving unit that receives correction information of the inventory of materials from a user terminal, when there is a reception of the correction information, it is preferable that the update unit updates the inventory information in the storage unit based on the correction information. For example, when a construction manager checks the actual inventory and finds it different from the inventory information stored in the inventory management processing apparatus, and transmits (uploads) the inventory correction information from the user terminal of the construction manager to the inventory management processing apparatus, the inventory management processing apparatus corrects the inventory information based on the correction information. Further, the present invention is an inventory management processing apparatus for managing the inventory quantity of materials for an auxiliary construction method of mountain tunnel construction at a construction site, comprising a storage unit that stores relationship information representing the relationship between the reset count of the integrated processing of the injection quantity of the injection material injected by an injector into the surrounding ground of the mountain tunnel during construction and the usage quantity of the material, and using the relationship information for calculating the inventory quantity based on the acquisition information of the reset count by an injector-side processing apparatus provided in the injector and the relationship information.

Mode for Carrying Out the Invention

[0014] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. As shown in FIG. 1, the inventory management processing system 10 for the tunnel auxiliary construction method of the present embodiment includes an injection machine side processing device 20, an inventory management processing device 30, a user terminal 40 of the construction manager A, and a user terminal 50 of the material supplier B. For example, the injection machine side processing device 20 is configured by a notebook personal computer (PC). The inventory management processing device 30 is configured by a server computer such as a cloud. The user terminals 40 and 50 are configured by a notebook personal computer, a desktop personal computer, a tablet, a smartphone, or other PCs. These computers 20, 30, 40, and 50 can communicate with each other via a public communication network 11 such as the Internet line. Preferably, the inventory management processing device 30 has a web page of inventory information, and the web page can be viewed by the browsers of the user terminals 40 and 50.

[0015] As shown in FIG. 1, the injection machine side processing device 20 (injection machine side computer) is arranged in the tunnel 1 under construction. A number of (only one is shown in FIG. 1) advance pipes (or hollow bolts) 3 are driven into the natural ground 2 around the tunnel 1. An injection machine 60 is installed in the tunnel 1. The injection machine 60 includes a plurality of (only one is shown in FIG. 1) injection pumps 61, an operation panel 62, and a programmable logic controller (PLC) 63. An injection hose 64 extending from the injection pump 61 is connected to the advance pipe 3 into which the injection material is to be injected. As the injection material 4, for example, a urethane-based foaming resin such as silica resin is sent out from the injection pump 61, passes through the injection hose 64 and the inside of the advance pipe 3, and is injected into the surrounding natural ground 2 and cured. Thereby, the natural ground 2 is stabilized. The internal space of the advance pipe 3 constitutes the injection hole 3a of the injection material 4.

[0016] As shown in FIG. 2, in addition to the monitor 62g, the operation panel 62 includes an operation start knob 62a for the injection pump 61, an operation stop knob 62b, an injection flow rate setting volume 62c, and a construction method type designation knob There are provided a construction method type designation knob 62d, a reset button 62e, a total reset button 62f, and the like. The construction method type designation knob 62d is for designating the specific construction method type of the tunnel auxiliary construction method to be constructed. Examples of the construction method type include the AGF method, the Fp (forepoling) method, the mirror bolt method, and the like. In any of these construction methods, more than 20 to 30 types of materials are used.

[0017] The reset button 62e resets data such as the integrated injection amount for each injection hole 3a. Pressing the reset button 62e indicates the completion of injection for one injection hole 3a. The number of resets corresponds to the number of injected injection holes 3a, that is, the number of advance steel pipes 3. The total reset button 62f is pressed when the injection work for one tunnel cross-section is completed. Pressing the total reset button 62f indicates the completion of the tunnel auxiliary construction method for one tunnel cross-section.

[0018] As shown in FIG. 2, the PLC 63 includes an arithmetic processing unit 63a, an input / output unit 63b, and a LAN communication unit 63c. The arithmetic processing unit 63a is constituted by a microprocessor or a micro control unit. Connected to the input / output unit 63b are input devices such as the operation panel 62 and the injection pressure sensor 65, and output devices such as an inverter 68 (pump drive circuit). The injection pressure sensor 65 detects the injection pressure of the injection material 4. Based on commands from the operation start knob 62a, the operation stop knob 62b, etc., the PLC 63 performs operation control of the injection pump 61 via the inverter 68. And injection information of the injection material 4 is acquired by the PLC 63. The injection information includes the construction method type, the injection amount of the injection material 4, the number of resets (the number of advance steel pipes 3), the injection time, and the like. The injection amount (kg) may be calculated by time integration of the injection flow rate (kg / min), may be calculated by the product of the discharge flow rate per rotation of the injection pump 11 and the number of rotations, or may be calculated from the integrated value of the flow meter.

[0019] As shown in FIG. 1, further, the injector 60 is equipped with an injector-side processing device 20 composed of the notebook PC. As shown in FIG. 2, the injector-side processing device 20 includes a CPU 21, a display 22, a storage unit 23, and a communication unit 24. The injector-side processing device 20 and the PLC 63 are connected to each other via a wired local area network (LAN) 66 so as to be capable of data communication. The injection information from the PLC 63 is stored in the storage unit 23. The injector-side processing device 20 functions as a data logger for storing the injection information.

[0020] More preferably, the injector-side processing device 20 has a function (program) of using the injection information to display the injection status for each injection hole of each tunnel cross-section in the form of a graph or chart. Preferably, as the chart, a chart in which the injection status for each injection hole is color-coded and displayed in a figure simulating the tunnel cross-section is created. Although not shown in the figure, graphs or charts showing the same injection status are also displayed on portable terminals such as the smartphones and tablets of the construction manager A and the construction contractor C. As a result, the injection status can be intuitively grasped in real time.

[0021] As shown in FIG. 3, the inventory management processing device 30 (inventory management computer) includes a processing unit 31 and a storage unit 32. The processing unit 31 is composed of a CPU or the like and has functions as an injection information reception unit 31a, an update unit 31b, a transmission processing unit 31c, a shipment information reception unit 31d, a correction reception unit 31e, and the like.

[0022] The storage unit 32 stores inventory information 32a of various materials used in the tunnel auxiliary construction method, reference quantity information 32b of the standard quantity of the inventory quantity of each material, a relational database 32d (relational information), and an inventory management program 32p for the tunnel auxiliary construction method. The inventory information 32a can be updated at any time.

[0023] The reference quantity information 32b is set within a range where no inventory shortage occurs in consideration of, for example, the predicted quantity of each material consumed per day and the average number of days from the shipment instruction of each material to its arrival at the construction site.

[0024] As shown in FIG. 4, the relational database 32d is data showing the relationship between the usage quantity of related materials and the injection information, and is created for each type of construction method such as the AGF method, the Fp method, and the mirror bolt method. In short, since the materials required according to the type of construction method are roughly determined, and the approximate usage quantity (unit usage quantity) of each material per unit number or unit length of the injection holes 3a is empirically known, this has been made into a database.

[0025] For example, in a general AGF method, the unit usage quantity of the tip pipe (number per injection hole) is 1, the unit usage quantity of the intermediate pipe is 2, and the unit usage quantity of the terminal pipe is 1. When the pilot bit needs to be worn out and replaced on average every two injection holes, the unit usage quantity of the pilot bit per injection hole is set to 0.5. When it is predicted that the wear rate is faster than the average in order to excavate hard rock, the unit usage quantity may be made smaller by multiplying by a correction coefficient.

[0026] The inventory management program 32p for the tunnel auxiliary construction method causes the inventory management processing device 30 (inventory management computer) to execute injection information reception processing, update processing, transmission processing, shipping information reception processing, correction reception processing, etc.

[0027] During the construction of Tunnel 1, the inventory management of various materials for the auxiliary construction method is performed as follows by the inventory management processing system 10 for the tunnel auxiliary construction method. For the sake of simplicity of explanation, it is assumed that the current inventory quantity of each material is correctly stored in the storage unit 32. In response to operations of the operation knobs 62a to 62f etc. of the operation panel 62, the PLC 63 controls the injection pump 61 and transmits injection information such as the type of construction method, the injection quantity of the injection material 4, the number of reset times (number of advance steel pipes 3), and the injection time to the injection machine side processing device 20 at any time. The injection machine side processing device 20 acquires the injection information from the PLC 63 and stores it in the storage unit 23.

[0028] When the injection work for all the injection holes 3a in the tunnel cross-section of 1 is completed, the total reset button 62f is pressed by the contractor C. The pressing information of the total reset button 62f is transmitted from the PLC 63 to the injection machine side processing device 20. Upon receiving this, the injection machine side processing device 20 transmits the injection information of the injection holes 3a included in the tunnel cross-section to the inventory management processing device 30. Note that the timing of the transmission is not limited to when the total reset button 62f is pressed. It may be at regular intervals, each time the injection machine side processing device 20 acquires injection information from the PLC 63, or when the accumulated amount of injection information in the injection machine side processing device 20 reaches a predetermined level or more.

[0029] As shown in the flowchart of FIG. 5, in the inventory management processing device 30, the following processing is executed by the program 32p. First, the processing unit 31 as the injection information reception unit 31a receives the injection information from the injection machine side processing device 20 (steps 100 - 101).

[0030] Next, the processing unit 31 as the update unit 31b updates the inventory information 32a in the storage unit 32 based on the received injection information (step 102). Specifically, the unit usage quantity of the related materials per injection hole 3a in the corresponding construction method type is read from the related database 32d. The usage quantity of each material after the previous update is calculated from the unit usage quantity and the number of injection holes in the injection information. The calculated usage quantity is subtracted from the inventory quantity currently stored in the storage unit 32, and the inventory quantity after the subtraction is overwritten and stored in the storage unit 32 as the new inventory information 32a.

[0031] Furthermore, the processing unit 31 as the transmission processing unit 31c transmits the inventory information in the storage unit 32 to the utilization terminals 40, 50 under certain conditions. For example, when the browsers of the user terminals 40 of construction manager A or the user terminal 50 of material supplier B access the web page of the inventory management processing device 30 and issue a request to view inventory information, using this viewing request as the certain condition (step 103), the inventory management processing device 30 transmits the inventory information in the storage unit 32 to the user terminals 40 and 50 (step 104).

[0032] It is preferable that the web page of the inventory management processing device 30 is provided with a viewing page for the inventory information of each material. Thereby, construction manager A and material supplier B can view the inventory information through the browsers of the user terminals 40 and 50, and can always grasp the inventory status. The browser may be a general-purpose Internet browser or a dedicated browser for the inventory management processing system 10 for the tunnel auxiliary construction method.

[0033] In addition, the processing unit 31 monitors whether the inventory quantity of each material in the inventory information of the storage unit 32 is less than the reference quantity of the reference quantity information 32b (step 105), uses the situation when it is less as the certain condition, and transmits the inventory information to the user terminals 40 and 50 (step 106). The transmission format is preferably an email. The email may be sent to the user terminal 40 of construction manager A, and a carbon copy thereof may be sent to the user terminal 50 of material supplier B.

[0034] Construction manager A and material supplier B who receive the email can grasp which materials are about to be out of stock. Construction manager A can accurately issue a shipping instruction for the material. Material supplier B can prepare for the shipment of the material and can promptly ship it when receiving the shipping instruction.

[0035] More preferably, at least the email addressed to the user terminal 40 of construction manager A is attached with a shipping instruction form for material supplier B. A copy of the shipping instruction form may also be attached to the email addressed to the user terminal 50 of material supplier B. More preferably, the shipping instruction form has the identification information (product name, model, etc.) of the materials that are below the standard quantity and the predicted required shipping quantity filled in by the processing unit 31. This can greatly reduce the labor of the construction manager A in creating the shipping instruction form. Furthermore, it can prevent an excess or deficiency in the shipping quantity.

[0036] When the material supplier B ships the materials upon receiving the shipping instruction from the construction manager A, the shipping information including the identification information (product name, model, etc.), shipping quantity, expected delivery date and time, etc. of the materials is transmitted (uploaded) to the inventory management processing device 30 by the browser of the utilization terminal 50.

[0037] The processing unit 31 as the shipping information receiving unit 31d in the inventory management processing device 30 receives the shipping information from the utilization terminal 50 (steps 107 to 108). It is preferable that a shipping information receiving page for receiving the shipping information is provided on the web page of the inventory management processing device 30. Furthermore, the processing unit 31 as the update unit 31b updates the inventory information 32a in the storage unit 32 based on the received shipping information (step 109). Specifically, the shipping quantity in the shipping information is added to the inventory quantity of the current inventory information 32a regarding the materials in the shipping information, and the quantity after addition is overwritten and saved as the new inventory information 32a. The timing of the update (overwrite save) based on the shipping information may be at the time of receiving the shipping information, or it may be the expected delivery date and time in the shipping information. This can reflect the shipping details in the inventory information.

[0038] When the construction manager A checks the actual inventory of each material at the tunnel construction site and obtains accurate inventory information, if the accurate inventory information is different from the inventory information in the inventory management processing device 30, the construction manager A transmits (uploads) the inventory correction information of the material to the inventory management processing device 30 by the browser of the utilization terminal 40.

[0039] In the inventory management processing apparatus 30, the processing unit 31 as the correction reception unit 31e receives the correction information from the user terminal 40 (steps 110 to 111). It is preferable that a correction reception page for receiving correction information is provided on the web page of the inventory management processing apparatus 30. Furthermore, the processing unit 31 as the update unit 31b updates the inventory information 32a in the storage unit 32 based on the received correction information (step 112).

[0040] As a result, the accurate inventory information obtained through actual inspection can be reflected in the inventory information 32a in the storage unit 43. That is, the estimation error of the inventory quantity by the injection information and the related database 32d can be corrected, and the accuracy of the inventory information 32a can be improved. Thus, according to the inventory management processing system 10, by supporting the inventory management of the materials used in the tunnel auxiliary construction method, the burden on the construction manager A and the like can be reduced. The general inventory status of the materials can be grasped, and the labor and effort required for inventory management by the construction manager A can be significantly reduced.

[0041] The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit thereof. For example, the inventory management processing apparatus 30 (inventory management computer) may be a non-cloud server computer, a notebook personal computer (preferably a stationary notebook personal computer), or a desktop personal computer. The injection machine side processing apparatus 20 (injection machine side computer) is not limited to a notebook PC, and may be a desktop PC, a tablet, or a smartphone. The flowchart shown in FIG. 5 is an example, and the processing order and the like may be appropriately changed. For example, the order of steps 107 to 109 and steps 110 to 112 may be interchanged, or the determination processes of steps 107 and 110 may be performed in parallel.
