Summary of the Invention

Problems to be Solved by the Invention

[0004] If various sensors are used as in the monitoring system shown in Patent Document 1 above, the excavation depth and the excavation speed can be directly measured. However, in order to simplify the system, it is preferable to obtain various information with as few devices as possible. For this reason, another method for deriving the excavation depth is also required.

[0005] In consideration of the above facts, an object of the present invention is to provide a ground excavation management system and a ground excavation management method capable of deriving an excavation depth.

Means for Solving the Problems

[0006] The ground excavation management system according to claim 1 is a ground excavation management system used in a casing method in which a casing is added and built in by rotating and pressing to cut the ground, and includes a measuring device that measures the length and height of the casing, and a management device that stores the measurement result and the measurement time, calculates the total length of the added casing, and calculates the excavation depth from the difference between the total length and the height.

[0007] In the ground excavation management system of claim 1, a measuring device measures the length of the casing. For example, the measuring device measures the length of the casing before it is inserted into the ground. The management device stores the measurement result and measurement time, so it can manage the measurement value and the casing in association. The management device can then calculate the total length of the extended casing from the lengths of each casing.

[0008] The measuring device also measures the height of the casing. This allows the control device to determine the height of the portion of the extended casing that protrudes above ground. The control device can then calculate the excavation depth of the casing underground by subtracting this height from the total length of the casing.

[0009] The ground excavation management system of claim 2 is the ground excavation management system of claim 1, wherein the management device calculates and records the speed of the excavation work from the measurement time.

[0010] In the ground excavation management system of claim 2, the progress of the excavation work can be grasped hour by hour based on the measurement time of the length and height of the casing. This makes it possible to calculate the speed of the excavation work.

[0011] The ground excavation management method of claim 3 is a ground excavation management method used in a casing method in which casing is extended and erected and rotary pressed into place to cut the ground, comprising the steps of: measuring the length of the casing before inserting it into the ground and storing it together with the measurement time; measuring the height of the casing in the state inserted into the ground on the ground and storing it together with the measurement time; calculating the total length of the extended casing and calculating the excavation depth from the difference between the total length and the height.

[0012] In the ground excavation management method of claim 3, the length of the casing is measured. For example, the length of the casing before insertion into the ground is measured. The measurement results are stored along with the measurement time, so that the measured value and the casing can be managed in association. Then, the total length of the extended casing is calculated from the lengths of each casing.

[0013] Furthermore, this ground excavation management method involves measuring the height of the casing. This allows us to determine the height of the portion of the extended casing that protrudes above ground. By subtracting this height from the total length of the casing, we can then calculate the excavation depth of the casing underground. [Effects of the Invention]

[0014] According to the present invention, the drilling depth can be derived. [Brief explanation of the drawing]

[Figure 5] This flowchart shows an example of an excavation management process according to an embodiment of the present invention. [Modes for carrying out the invention]

[0016] Hereinafter, a ground excavation management system and a ground excavation management method according to an embodiment of the present invention will be described with reference to the drawings. Components denoted by the same reference numerals in each drawing mean the same components. However, unless otherwise specified in the specification, each component is not limited to one, and a plurality of them may exist.

[0017] Also, descriptions of overlapping configurations and reference numerals in each drawing may be omitted. Note that the present disclosure is not limited to the following embodiments, and appropriate changes can be made and implemented, such as omitting configurations, replacing with different configurations, and using a combination of one embodiment and various modification examples within the scope of the object of the present disclosure.

[0018] <Ground Excavation Management System> FIG. 1(A) shows a ground excavation management system 80 according to an embodiment of the present invention. The ground excavation management system 80 includes a management device 10, an excavation device 20, and a measurement device 30.

[0019] (Excavation Device) The excavation device 20 excavates the ground G using a casement 40 that can be added. A casement installed by a crawler crane or the like is installed in the excavation device 20. The excavation device 20 cuts the ground while rotationally pressing the casement 40. In addition, the earth and sand and the structure M inside the casement 40 are excavated and discharged using a hammer grab (not shown).

[0020] When the casement 40A is inserted into the ground G to a predetermined depth, as shown in FIG. 1(B), the casement 40B is added. In this specification, the added casement alone may be referred to as casements 40A, 40B,..., and the entire added casement may be referred to as the casement 40. When there is no need to distinguish between them, they may also be collectively referred to as the casement 40.

[0021] As shown in Fig. 1(C), when the casing 40B is inserted into the ground G to a predetermined depth, as shown in Fig. 1(D), the casing 40C is added. Then, as shown in Fig. 1(E), the casing 40C is inserted into the ground. By repeating such steps, the ground G is excavated.

[0022] (Measuring device) The measuring device 30 shown in Fig. 1(A) measures the length and height of the casing 40 on the ground. The "height" of the casing 40, that is, the height H1 of the top 42 of the casing 40, is calculated from the horizontal distance W1 between the measuring device 30 and the casing 40 and the elevation angle θ1 of the top 42 with respect to the measuring device 30. The height H2 of the bottom 44 of the casing 40 is also calculated in the same way. The length L1 of the casing 40 is calculated by the difference between the height H1 and the height H2.

[0023] In order for the measuring device 30 to easily recognize the top 42 and the bottom 44 of the casing 40, markings can be attached to these locations as necessary. The markings can be formed by applying paint to the casing 40, attaching a tape, etc., or attaching a measurement target.

[0024] [[ID=​​​​​​​​​The management device 10 is connected to the measuring device 30 by wired or wireless connection via a communication I / F unit 18 or an external I / F unit 19, which will be described later, and can exchange various information with the measuring device 30. The management device 10 may be located at the excavation site where the excavation equipment 20 is installed, or it may be located at an office or other location geographically distant from the excavation site.

[0027] <Electrical configuration of the control device> As shown in Figure 2, the management device 10 includes a CPU 11, a memory 12 as a temporary storage area, a non-volatile storage unit 13, an input unit 14, a display unit 15 such as a liquid crystal display, a media read / write (R / W) device 16, a communication interface (I / F) unit 18, and an external I / F unit 19. The CPU 11, memory 12, storage unit 13, input unit 14, display unit 15, media read / write device 16, communication I / F unit 18, and external I / F unit 19 are connected to each other via bus B1.

[0028] The CPU 11 controls the overall operation of the management device 10. The media read / write device 16 reads information written to the recording medium 17 and writes information to the recording medium 17. The communication interface 18 is an interface for enabling communication between the management device 10 and, for example, servers located outside the management device 10 or various terminals used by users. Communication standards such as Wi-Fi (registered trademark), Bluetooth (registered trademark), and LAN (Local Area Network) can be used in the communication interface 18.

[0029] (Storage part) The storage unit 13 is implemented by an HDD (Hard Disk Drive), SSD (Solid State Drive), flash memory, etc. The storage unit 13, as a storage medium, stores an information processing program 13A. The information processing program 13A is stored in the storage unit 13 when the recording medium 17 on which the information processing program 13A is written is set in the media read / write device 16, and the media read / write device 16 reads the information processing program 13A from the recording medium 17. The CPU 11 reads the information processing program 13A from the storage unit 13, loads it into memory 12, and sequentially executes the processes contained in the information processing program 13A. The drilling information database 13B, which will be described later, is stored in this storage unit 13.

[0030] (Input section) The input unit 14 is used to input various types of information. For example, the administrator of the ground excavation management system 80 can use the input unit 14 to start and stop the information processing program 13A.

[0031] (Display) The display unit 15 is used to display various types of information. For example, the display unit 15 displays information for starting and ending the information processing program 13A.

[0032] <Functional configuration of the control device> Next, with reference to Figure 3, the functional configuration of the management device 10 according to this embodiment will be described. As shown in Figure 3, the management device 10 includes an acquisition unit 11A, a calculation unit 11B, and a control unit 11C. The CPU 11 of the management device 10 functions as the acquisition unit 11A, the calculation unit 11B, and the control unit 11C by executing the information processing program 13A.

[0033] (Control Unit) The control unit 11C controls the measuring device 30. For example, the control unit 11C controls the timing for measuring the length and height of the casing.

[0034] Specifically, as shown in Figures 1(A), (B), and (D), the control unit 11C causes the measuring device 30 to measure the lengths of the casings 40A, 40B, 40C, ... at the time the casings 40 are installed (extended). In addition, the control unit 11C causes the measuring device 30 to measure the height H1 of the casings 40 at predetermined intervals.

[0035] The "timing of casing 40 installation" can be determined by having a worker input the information into the control device 10 each time casing 40 is installed, or by using a time based on a plan such as a work schedule. Alternatively, the installation of casing 40 can be determined by a sensor provided in the measuring device 30. Or, if a camera is used as the measuring device 30, the installation of casing 40 can be determined by image analysis by the measuring device 30 or the control device 10.

[0036] (Acquisition Department) The acquisition unit 11A acquires the length and height of the casing 40 measured by the measuring device 30. Specifically, the acquisition unit 11A acquires the lengths L1, L2, L3, ... of individual casings measured by the measuring device 30 and records them, along with the measurement time, in the excavation information database 13B shown in Figure 4.

[0037] Furthermore, the acquisition unit 11A acquires the height H1 of the casing unit measured by the measuring device 30 and records it in the excavation information database 13B along with the measurement time.

[0038] When a camera is used as the measuring device 30, the acquisition unit 11A can acquire the image captured by the measuring device 30 and derive the length and height of the casing 40 through image analysis.

[0039] (Calculation section) The calculation unit 11B uses the length and height of the casing 40 to calculate the excavation depth of the casing 40 underground and records it in the excavation information database 13B shown in Figure 4. The calculation unit 11B also calculates the excavation speed from the measurement time of the length and height of the casing 40 and records it in the excavation information database 13B.

[0040] Specifically, as shown in Figure 1(B), for example, the calculation unit 11B can calculate the total length ΣL (ΣL = L1 + L2 + ...) of the extended casing 40 from the length L1 of the casing 40A, the length L2 of the casing 40B, ... measured by the measuring device 30.

[0041] Furthermore, the calculation unit 11B can calculate the tip depth of the casing 40 underground by subtracting the height H1 of the casing 40 from the total length ΣL of the extended casing 40. In other words, the control device 10 can derive the excavation depth D1.

[0042] <Excavation Management Processing> The CPU 11 of the management device 10 executes the "excavation management process" shown in Figure 5 in response to an instruction to start the excavation management process from the administrator of the ground excavation management system 80 via the input unit 14.

[0043] When the drilling management process is executed, in step S102, the CPU 11 waits for the casing 40 to be installed on the drilling machine 20. Once the casing 40 is installed on the drilling machine 20, the process proceeds to step S104.

[0044] In step S104, the CPU 11 controls the measuring device 30 to measure the length L1 and height H1 of the casing 40 (see Figure 1(A)), and records the measured length L1, height H1, and measurement time in the excavation information database 13B.

[0045] Furthermore, the CPU 11 records the measured length L1 as the total length ΣL of the casing 40 in the drilling information database 13B (see, for example, the recorded result for measurement time 07:50 in Figure 4). After step S104, the process proceeds to step S106.

[0046] In step S106, the CPU 11 waits for a predetermined amount of time to elapse. Once the predetermined time has elapsed, the process proceeds to step S108.

[0047] In step S108, the CPU 11 controls the measuring device 30 to measure the height H1 of the casing 40 and records the measured height H1 in the excavation information database 13B.

[0048] Furthermore, the CPU 11 calculates the drilling depth D1 from the difference between the total length ΣL and height H1 of the casing 40 and records it in the drilling information database 13B. For example, in the recorded result at measurement time 08:20 in Figure 4, the total length of the casing 40 is 6m and the height is 4m, so the drilling depth is 2m.

[0049] Furthermore, the CPU 11 calculates and records the excavation speed from the measurement result of length L1 and the measurement time. For example, since the 6m casing 40 installed at measurement time 07:50 has been inserted into the ground G at measurement time 08:20, the excavation speed is 4m / h. After step S108, the process moves to step S110.

[0050] In step S110, the CPU 11 determines whether or not a new casing 40 has been installed on the drilling machine 20. If the determination in step S110 is positive, the process returns to step S104. On the other hand, if the determination in step S110 is negative, the process proceeds to step S112.

[0051] In step S112, the CPU 11 determines whether the timing for the end of the "excavation management process" has arrived. The timing for the end of the "excavation management process" arrives in response to a termination instruction for the excavation management process from the administrator of the ground excavation management system 80 via the input unit 14. If the determination in step S112 is positive, the CPU 11 terminates the "excavation management process". On the other hand, if the determination in step S112 is negative, the process proceeds to step S106. In other words, step S108 is repeated at predetermined time intervals until a new casing 40 is installed.

[0052] <Effects> In the ground excavation management system 80 according to an embodiment of the present invention, as shown in Figure 1, the measuring device 30 measures the lengths L1, L2, L3, ... of the casings 40A, 40B, 40C, ...

[0053] For example, the measuring device 30 measures the lengths L1, L2, L3, ... of the casings 40A, 40B, 40C, ... before they are inserted into the ground G. The management device 10 stores the measurement results and measurement time, so that the measured values ​​and the casings can be managed in association.

[0054] The control device 10 can then calculate the total length of the extended casing, L1+L2+L3+..., from the lengths L1, L2, L3,... of each casing 40A, 40B, 40C,....

[0055] For example, the measuring device 30 measures the height H1 of the casing 40. This allows the control device 10 to determine the height of the portion of the extended casing 40 that protrudes above ground. The control device 10 can then calculate the excavation depth D1 of the casing underground by subtracting the height H1 from the total length of the casing L1 + L2 + L3 + ...

[0056] Furthermore, in the ground excavation management system 80 according to the embodiment of the present invention, the progress of the excavation work can be grasped hour by hour by measuring the lengths L1, L2, L3, ... and height H1 of the casing 40. This allows the speed of the excavation work to be calculated.

[0057] <Other Embodiments> In the above embodiment, the calculation unit 11B calculates the excavation speed, but the embodiments of the present invention are not limited to this.

[0058] For example, the pressing speed of the casing 40 may be measured by attaching a laser measuring instrument capable of measuring the movement speed of the object to the drilling device 20. A non-contact laser Doppler type measuring instrument can be used as the laser measuring instrument.

[0059] Furthermore, in the above embodiment, for example, the hardware structure of the processing unit that executes the acquisition unit 11A, the calculation unit 11B, and the control unit 11C can be any of the following types of processors. As mentioned above, these types of processors include a CPU, which is a general-purpose processor that executes software (programs) and functions as a processing unit, as well as programmable logic devices (PLDs), such as FPGAs (Field-Programmable Gate Arrays), which are processors whose circuit configuration can be changed after manufacturing, and dedicated electrical circuits, such as ASICs (Application Specific Integrated Circuits), which are processors with circuit configurations specifically designed to execute specific processes.

[0060] The processing unit may consist of one of these various processors, or it may consist of a combination of two or more processors of the same or different types (for example, a combination of multiple FPGAs, or a combination of a CPU and an FPGA). Alternatively, the processing unit may consist of a single processor. Some or all of these processors may be configured on the cloud. At least each of the processes described in the above embodiments may be executed by a processor on the cloud.

[0061] Examples of configuring a processing unit with a single processor include, firstly, a configuration where one or more CPUs and software combine to form a single processor, as is common in client and server computers, and this processor functions as the processing unit. Secondly, a configuration using a processor that realizes the functions of the entire system, including the processing unit, on a single IC (Integrated Circuit) chip, as is common in System-on-a-Chip (SoC) systems. Thus, the processing unit is configured, in terms of hardware structure, using one or more of the above-mentioned types of processors.

[0062] Furthermore, the hardware structure of these various processors can more specifically utilize an electrical circuit (circuitry) that combines circuit elements such as semiconductor elements. Thus, this disclosure can be implemented in various forms. [Explanation of symbols]
