Summary of the Invention

Problems to be Solved by the Invention

[0004] [[ID=##]] However, in the pile driving management system disclosed in Patent Document 1, as the vibration measurement unit, the vibration characteristics detected by vibration measuring instruments attached to the operation room of the drilling machine, the roof of the operation room, and the operation lever in the operation room, and the drilling depth are measured based on the amount of wire pay-out of the auger device provided on the mast. There is no guarantee that the vibration characteristics measured by the vibration measurement unit accurately reflect the vibration characteristics of the drilling head, and there is also no guarantee that the amount of wire pay-out accurately reflects the drilling depth.

[0005] For example, when attaching a vibration measuring instrument to the operating lever in the control room of an excavator, it was difficult to accurately detect the vibration characteristics of the drilling head because it was affected by various vibrations, including not only vibrations caused by drilling but also resonances of structural members in each part of the excavator. Furthermore, when detecting the amount of wire payout, it was difficult to accurately detect the amount of wire payout or hoisting due to slippage and play in the wire hoisting device, and the depth was relative to the ground, making it difficult to accurately manage the depth in a geodetic reference system, for example. This also made objective evaluation difficult when reusing driven piles.

[0006] In view of the above-mentioned conventional problems, the object of the present invention is to provide a drilling support system that can confirm in real time when the drilling head has reached a target specific depth, and can also manage drilling information with high accuracy. [Means for solving the problem]

[0007] To achieve the above objective, the first characteristic configuration of the drilling support system according to the present invention is a drilling support system that assists in drilling work to drill a target ground to a specific depth by rotating a drilling rod equipped with a drilling head at its tip with an auger device, comprising: a total station that tracks a prism attached to the auger device to measure vertical data corresponding to the depth of the drilling head and horizontal data of the auger device; an ammeter that measures the drive current data of the auger device; and a communication device that inputs drilling data including the measured vertical data, the horizontal data and the drive current data from the ammeter to the total station. The system comprises an interface, a storage device that stores the drilling data obtained via the communication interface in a temporally related manner, and also stores boring data including geological and depth-N value characteristic values ​​of the target ground to be drilled from the ground surface to the specified depth obtained in the boring survey, a data processing unit that calculates the depth of the drilling head from the drilling data stored in the storage device, associates the boring data with the drilling data using the depth of the boring data as an indicator, and generates a monitor image that allows the drilling state to be recognized in real time, and an image display unit that displays the monitor image generated by the data processing unit.

[0008] By tracking a prism attached to the auger device with a total station, the position of the drilling head at the tip of the auger device can be accurately detected as horizontal data (X,Y coordinate data) and vertical data (Z coordinate data) in three-dimensional X,Y,Z coordinates corresponding to latitude, longitude, and altitude in a geodetic reference system. Based on these values, the horizontal vibration characteristics and drilling depth of the auger device can be captured with high accuracy.

[0009] The data processing unit then acquires the horizontal and vertical data and the drive current data of the auger device via a communication interface. By managing these data in real time and relating them temporally, the depth of the drilling head and the strength of the ground reaction force applied to the drilling head are obtained. This data is then compared with the geological conditions and depth-N value characteristics of the target ground from the surface to a specific depth, which are pre-stored in the memory device as results of boring surveys. A monitor image is generated that allows for comparison of these values ​​using depth as an indicator and is displayed on the image display unit. This allows, for example, a pile driver operator to visually inspect the monitor image and appropriately determine when the drilling head has reached a specific depth. Such drilling data is stored in the memory device as, for example, latitude, longitude, and altitude in a geodetic datum, and can be effectively used later as management data for each pile. The specific depth refers to the depth necessary for stable pile installation, and in the case of friction piles, it refers to the depth corresponding to ground with a specific N value.

[0010] The second characteristic configuration is that, in addition to the first characteristic configuration described above, the specific depth corresponds to the depth of the supporting layer.

[0011] If the pile needs to reach a supporting layer such as bedrock to achieve stable installation, then the depth to the supporting layer should be designated as the specified depth.

[0012] The third characteristic configuration is that, in addition to the second characteristic configuration described above, the monitor image includes the horizontal deviation from the initial position of the drilling rod obtained based on the horizontal data, as well as the geological and / or N-value.

[0013] The horizontal deviation of the drilling rod from its initial position can be determined from the horizontal data of the auger device included in the drilling data, and the horizontal data that changes over time can be understood as the horizontal vibration characteristics of the drilling head. By comparing the geology and / or N-value from the ground surface to the drilling depth of the target ground, which are the results of the boring survey, with the horizontal vibration characteristics on the monitor image, it becomes possible to visually confirm the drilling depth of the drilling head, i.e., the progress of the drilling work.

[0014] The fourth characteristic configuration, in addition to the second characteristic configuration described above, further includes a sound collection device for measuring drilling sound data from the auger device, the storage device stores the drilling sound data obtained via the communication interface as drilling data, and the data processing unit adds the drilling sound data to the monitor image using the depth of the boring data as an indicator.

[0015] By incorporating drilling sound data into the drilling data, it becomes possible to visually confirm the drilling depth of the drilling head by comparing the geological data from the surface to the drilling depth of the target ground (which is the result of the boring survey) with the drilling sound data on the monitor image. The reaction force that the drilling head receives differs depending on the geological conditions, and the progress of the drilling work can be objectively confirmed visually as a change in drilling sound.

[0016] The fifth characteristic configuration is that, in addition to the fourth characteristic configuration described above, the monitor image includes the horizontal deviation from the initial position of the drilling rod obtained based on the horizontal data, as well as the geological and / or N-value.

[0017] By comparing the results of the boring survey—including the geological characteristics and / or N-value from the ground surface to the drilling depth—with the horizontal vibration characteristics and drilling noise data on the monitor image, it becomes possible to more accurately visually confirm the drilling depth of the drilling head, i.e., the progress of the drilling work.

[0018] The sixth characteristic configuration is that, in addition to the fourth characteristic configuration described above, the data processing unit extracts characteristic frequency components generated from the ground during excavation from the excavation sound data using a Fourier transform and adds them to the monitor image.

[0019] By performing a Fourier transform on the excavation sound data, characteristic frequency components generated from the ground during excavation can be extracted, thereby reducing the impact of noise.

[0020] The seventh characteristic configuration further includes an encoder that indicates the rotation data of the auger device in addition to the second characteristic configuration described above. The storage device stores the rotation data obtained via the communication interface as the drilling data, and the data processing unit calculates the depth of the excavation head based on the vertical direction data and the rotation data.

[0021] By adding the rotation data, which is the signal of the encoder provided in the auger device, to the drilling data, it becomes possible to appropriately determine whether drilling is in progress based on the rotation direction of the excavation head, and it becomes possible to appropriately extract the horizontal direction data and current data in the situation where the excavation head is excavating the ground based on the vertical direction data and the rotation data.

[0022] The eighth characteristic configuration is that, in addition to the first characteristic configuration described above, the data processing unit stores the drilling data and the monitor image from the start to the end of drilling in the storage unit in a distinguishable manner as drilling work record information.

[0023] It becomes possible to verify later as evidence data that the drilling work has reached an appropriate depth, and it is possible to increase the possibility of reusing the piles in the future.

[0024] The ninth characteristic configuration is that, in addition to the first characteristic configuration described above, the monitor image generated by the data processing unit is displayed on the image display unit via a communication line, and is configured to be viewable at any one or a plurality of locations including the driver's seat of the pile driver, the on-site office, and the remote management office.

[0025] Since the monitor image can be viewed by others than the operator of the pile driver, it becomes possible for managers, etc. to grasp the progress of the work remotely.

Advantages of the Invention

[0026] As described above, according to the present invention, it has become possible to provide a hole drilling support system that can confirm in real time that the drilling head has reached a target specific depth and can accurately manage drilling information.

Brief Explanation of the Drawings

[0027] [Figure 1] Explanation diagram of the hole drilling support system [Figure 2] Explanation diagram of the boring data [Figure 3] Explanation diagram showing the procedure of the hole drilling support system [Figure 4] (a) is an explanatory diagram of a monitor image during the hole drilling operation, and (b) is an explanatory diagram of another aspect of the monitor image during the hole drilling operation [Figure 5] (a) is an explanatory diagram of a monitor image during the hole drilling operation, and (b) is an explanatory diagram of the monitor image at the end of the hole drilling operation

Modes for Carrying Out the Invention

[0028] Hereinafter, an aspect of a hole drilling support system for smoothly advancing the hole drilling operation using a pile driver will be described based on the drawings. [Configuration of the pile driver] As shown in FIG. 1, the pile driver 10 includes a swivel base 2 provided with a crawler traveling device 1, a leader 4 erected and supported in front of the driver's seat 3 provided on the swivel base 2, and a pair of left and right cylinder mechanisms 5 for adjusting the erected posture of the leader 4.

[0029] An auger device 7 that rotatably supports a drilling rod 6 with a drilling head 6A attached to its tip is suspended and supported by a wire on the leader 4. The drilling rod 6 rotationally driven by a motor is lowered from above the designed pile core position to be drilled, and a hole for pile driving is drilled. An operator operates a plurality of joysticks in the driver's seat 3 to expand and contract the left and right cylinder mechanisms 5, thereby adjusting the posture of the leader 4, and thereby adjusting the drilling position by the drilling head 6A during hole drilling. Then, the wire is paid out and the hole drilling operation proceeds.

[0030] Once drilling is complete, a pile holding mechanism is attached to the leader 4, and RC piles, centrifugal prestressed concrete piles (PC piles), etc., are held by the pile holding mechanism and driven into the excavated hole by the auger device 7.

[0031] For example, the diameter of the leader 4 is approximately 1000 mm, the diameter of the pile is 600-800 mm, and the diameter of the auger device 7 is set such that the diameter of the hole drilled by the auger device 7 is approximately 200 mm larger than the diameter of the pile. In other words, the diameter of the hole drilled by the auger device 7 is set to be sufficiently larger than the diameter of the pile that will be driven into that hole.

[0032] [Drilling support system] The drilling support system 100 is a drilling support system for assisting operators performing drilling work, which involves rotating a drilling rod 6 equipped with a drilling head 6A at its tip using an auger device 7 to drill into the target ground to a specific depth. The specific depth refers to the depth required for stable pile installation, and in the case of friction piles, it refers to the depth corresponding to ground exhibiting a specific N value. If it is necessary to reach a supporting layer such as bedrock as the depth required for stable pile installation, the specific depth will be the depth to the supporting layer. The following describes an example in which the specific depth is set to the depth to the supporting layer.

[0033] The drilling support system 100 includes a computer 40 capable of communicating with external devices via a communication medium such as the internet, a total station 20 which is a surveying instrument, an ammeter 80 incorporated into the auger device 7 that measures the drive current data of the motor that rotates the drilling rod 6, an encoder device 85 that monitors the rotational state of the drilling rod 6, a sound collection device 90 installed on the ground surface near the pile driver 10, one or more communication interfaces 30, and a tablet computer 60A installed in the driver's seat 3 of the pile driver 10 as a terminal that functions as an image display unit 60. A Wi-Fi router or the like can be suitably used as the communication interface 30. Furthermore, the computer 40 and the tablet computer 60A are configured to display the same image on both sides via an image sharing system server connected via the internet.

[0034] The total station 20 automatically tracks the prism 70 attached to the auger device 7 to measure vertical data corresponding to the depth of the drilling head 6A and horizontal data of the auger device 7, and transmits the measured data to the computer 40 via the communication interface 30. The horizontal and vertical data are, for example, horizontal data (X,Y coordinate data) and vertical data (Z coordinate data) represented by three-dimensional X,Y,Z coordinates corresponding to the latitude, longitude, and altitude in the geodetic datum. The horizontal data provides the horizontal vibration characteristics of the drilling head 6A, and the vertical data provides the drilling depth of the drilling head 6A. The drilling depth can be obtained by subtracting the offset from the prism 70 to the drilling head 6A from the vertical data.

[0035] The ammeter 80 can be composed of a current coil wrapped around the power line of the motor described above, and the drive current detected by the current coil is converted by an A / D converter and transmitted as current data to the tablet computer 60A via a short-range communication interface such as Bluetooth®. The sound collection device 90 consists of a microphone or the like that collects the drilling sound generated by the drilling head 6A driven by the auger device 7, and the collected drilling sound is converted by an A / D converter and transmitted as drilling sound data to the tablet computer 60A via a short-range communication interface such as Bluetooth®.

[0036] The computer 40 includes a storage device 50 consisting of a CPU board, a memory board, and a storage device such as an SSD or HD. A drilling support program is installed in the storage device 50, and the drilling support program is executed by the CPU mounted on the CPU board, causing the computer 40 to function as a data processing unit 45.

[0037] The storage device 50 stores, in a manner that allows for identification of each drilling operation, a set of drilling data that indicates the real-time drilling status. This data includes vertical and horizontal data collected by the computer 40 and measured by the total station 20, current data measured by the ammeter 80, drilling sound data measured by the sound collector, and rotation data of the auger device 7 measured by the encoder (such as two-phase encoder pulses that can identify the direction of rotation). The meaning of "temporarily related" is to ensure the simultaneity of each data. For this purpose, the measurement time of each data may be added as a timestamp, or the time collected by the computer 40 may be added as a timestamp. As long as the simultaneity of each data can be ensured, it is also possible to employ known methods other than timestamps.

[0038] The storage device 50 stores boring data, including the geological features from the ground surface to the bearing layer of the target ground to be excavated, and depth-N value characteristic values, obtained from a prior boring survey. An example of boring data is shown in Figure 2. With depth on the vertical axis, the thickness and changes of each layer of geology (sand layer, gravel layer, gravel layer, cohesive soil layer, silt layer, etc.) from the ground surface are displayed visually, and the N value characteristics are shown on the side.

[0039] The data processing unit 45 calculates the depth of the drilling head 6A from the drilling data stored in the storage device 50, associates the boring data with the drilling data using the boring data depth as an indicator, and generates a monitor image that allows for real-time recognition of the drilling status.

[0040] The data processing unit 45 determines the rotational state of the drilling rod 6 based on the vertical data measured by the total station 20 and the rotational data, which is the signal from the encoder. When the conditions are met that the drilling rod 6 is rotating in the drilling direction and that the depth of the drilling head 6A is changing in the depth direction based on the vertical data, it extracts drilling data as valid drilling data and generates a monitor image based on the extracted drilling data.

[0041] In other words, the data processing unit 45 can appropriately determine whether the drilling head 6A is rotating in the forward or reverse direction based on its rotational direction, and can appropriately extract horizontal and current data when the drilling head is drilling the ground based on the vertical and rotational data.

[0042] For example, drilling data from times other than drilling operations, such as when temporarily pulling out the drilling rod 6 to extend it, or when the drilling head 6A is stopped, is removed so that it does not appear as noise on the monitor image.

[0043] If the monitor image generated by the data processing unit 45 displays the horizontal deviation from the initial position of the drilling rod 6, obtained based on horizontal data, as well as the geological characteristics and / or N-value, then by comparing the monitor image with the geological characteristics and / or N-value from the ground surface to the drilling depth of the target ground, which are the results of the boring survey, and the horizontal vibration characteristics, it becomes possible to visually confirm the drilling depth of the drilling head, i.e., the progress of the drilling work.

[0044] When drilling sound data is displayed on a monitor image using the depth of the boring data as an indicator, the reaction force received by the drilling head differs depending on the geological conditions. This allows for objective visual confirmation of the progress of the drilling work as changes in drilling sound.

[0045] When the data processing unit extracts characteristic frequency components generated from the ground during excavation using Fourier transform (FFT) from the excavation sound data and adds them to the monitor image, the extraction of characteristic frequency components generated from the ground during excavation reduces the influence of noise from surrounding noise sources.

[0046] In other words, by tracking the prism 70 attached to the auger device 7 with the total station 20, the position of the drilling head 6A at the tip of the auger device 7 can be accurately detected as horizontal data (X,Y coordinate data) and vertical data (Z coordinate data) in three-dimensional X,Y,Z coordinates corresponding to latitude, longitude, and altitude in the geodetic reference system. Based on these values, the horizontal vibration characteristics and drilling depth of the auger device can be captured with high accuracy.

[0047] The monitor images generated by the data processing unit 45 are configured to be displayed via the image sharing system server on the tablet computer 60A installed in the driver's seat 3 of the pile driver 10, and on the display devices 60B of computers installed in multiple locations such as the site office and remote management offices.

[0048] When the drilling head 6A reaches the bearing layer, the unique horizontal vibration characteristics, acoustic characteristics, and current characteristics corresponding to the hard geological structure and large N-value of the bearing layer are displayed on the monitor image, and their extent is shown. In addition to the instantaneous current characteristics, the current characteristics include integrated current characteristics, which are calculated by integrating the instantaneous current characteristics by the data processing unit 45. The work done by the drilling head 6A on the geological structure can be determined from the integrated current characteristics, and the harder the geological structure, the larger the value of the integrated current characteristics.

[0049] By visually inspecting the monitor image displayed on the tablet computer 60A, the operator of the pile driver 10 can determine the depth of the drilling head 6A, the geological conditions where the drilling head 6A is located at that time, the N-value, and the horizontal vibration characteristics (such as amplitude and vibration frequency). This allows the operator to recognize from the monitor image that the depth of the pre-determined bearing layer has been reached.

[0050] The data processing unit 45 then stores the drilling data used to generate the monitor image in a memory device as, for example, latitude, longitude, and altitude in a geodetic datum, so that it can later be effectively used as management data for each pile.

[0051] Figure 3 shows the operation of the drilling support system. When the drilling support application program is started on the computer 40 (SA1), boring data from the drilling site is read from the storage device 50 (SA2). The operator sets the installation position and initial operating mode of the total station 20 (SA3), the prism 70 attached to the auger device 7 is sighted, and the system is set to automatic tracking mode (SA4).

[0052] Next, the display screen is shared via the image sharing system server so that the screen displayed on the display device 60B of the computer 40 is displayed on the display screen of a display device 60, such as a tablet computer 60A, installed in the driver's seat 3 of the pile driver 10 (SA5).

[0053] The operator touches the monitor image displayed on the tablet computer 60A, which starts the sampling of drilling data by the computer 40, after which the auger device 7 is activated, and drilling work begins. Horizontal and vertical data are read by the total station 20 and transmitted to the computer 40. Similarly, other drilling data such as current data and drilling sound data are sampled and transmitted to the computer 40 (SA5).

[0054] The data transmitted to the computer 40 is processed in a time-synchronized manner by the data processing unit 45 (SA6), and drilling data such as horizontal data and current data as the drilling head 6A is excavating the ground is extracted and stored in the storage device 50 (SA7). Next, the depth of the drilling head 6A is calculated based on the vertical data transmitted from the total station 20 from the drilling data stored in the storage device 50, and the boring data and drilling data are associated using the depth of the boring data stored in the storage device 50 as an indicator, and a monitor image that allows the drilling status to be recognized in real time is generated (SA8), and the monitor image is displayed on the display device 60 (SA9).

[0055] The process from step SA5 to step SA9 is repeated (SA10,N) until the operator of the pile driver 10 visually checks the monitor image in the driver's seat and determines that the drilling head 6A has reached the supporting layer. When it is determined that the drilling head 6A has reached the supporting layer (SA10,Y), the drilling operation is terminated and the drilling data is stored in the storage device 50 (SA11).

[0056] The drilling management data, including the drilling data stored in the memory unit 50, is assigned an individually identifiable ID and stored in a drilling database managed by a cloud server.

[0057] Figures 4(a), (b) and 5(a), (b) illustrate monitor images. As shown in Figure 4(a), the monitor image includes a project display area D1, a measurement start / stop switching area D2, and an excavation data display area D3.

[0058] Project display area D1 shows the site name for the pile driving work and the pile number indicating the drilling location, allowing each project to be managed individually. Measurement start / stop switching area D2 displays measurement start and measurement stop icons, as well as instantaneous values ​​of drilling depth and current. When the measurement start icon is touched, measurement of drilling data begins, and when the measurement stop icon is touched, measurement of drilling data ends, and the drilling data and other information are stored in the storage device 50.

[0059] The drilling data display area D3 has a horizontal vibration waveform display area in the upper section and display areas for the integrated current value, instantaneous current value, and N value relative to the drilling depth in the lower section. Above the horizontal vibration waveform display area, there are checkboxes to select the horizontal vibration waveform display interval, the integrated current value pitch, and whether to display the X or Y component of the horizontal vibration waveform. The horizontal vibration waveform display area is a horizontally elongated display area with amplitude (mm) on the vertical axis and time on the horizontal axis, and displays vibration data for the time width selected in the horizontal vibration waveform display interval. The display interval can be selected from 1 minute, 5 minutes, 10 minutes, and 30 minutes using a pull-down menu. The waveform of the component selected in the horizontal vibration waveform selection section is displayed. In this figure, a 1-minute display interval is selected, and the vibration waveform of the X component from 14:58:20 to 14:59:20 is displayed. Also, the integral pitch of the integrated current value is set to 50 mm. The integral pitch can be set in 50 mm increments up to 200 mm using a pull-down menu.

[0060] The lower display area of ​​drilling data display section D3 shows drilling data with depth (m) on the vertical axis and integrated current value, instantaneous current value, and N value on the horizontal axis. A checkbox is displayed on the far right to select whether to display the integrated current value, instantaneous current value, or N value. In addition, a bar graph display area indicating the drilling depth is set to the left of the drilling data display area of ​​drilling data display section D3, and the current drilling depth is shown as a bar graph in the display area up to 120% of the target drilling depth.

[0061] Figure 4(b) shows the vibration waveform of the X component from 14:44 to 15:14 with a 30-minute display interval selected. Figure 5(a) shows an example where both the X component and Y line segment of the horizontal vibration waveform are selected, while all other display conditions are set to the same settings as in Figure 4(a).

[0062] Figure 5(b) shows an example of an image for verification after the completion of drilling work, which is displayed by selecting the past data display area shown in the upper right of the monitor image in Figure 4(a). By specifying the site name and pile number in the upper left of the screen, the corresponding drilling data is read from the storage device 50 and displayed. By dragging the icon on the drilling depth specification bar at the far left of the screen, drilling data before and after the specified drilling depth is displayed. At this time, a vertical bar indicating the depth set by operating the icon is displayed in the horizontal vibration waveform display area, and a horizontal bar indicating the depth set by operating the icon is displayed in the display area for the integrated current value, instantaneous current value, and N value relative to the drilling depth. This monitor image makes it possible to verify whether the drilling work was performed appropriately even after the drilling work is completed. Although not shown in Figures 4 and 5, it is also possible to display drilling sound and geology by providing a checkbox that allows selection of display of drilling sound as drilling data and display of geology as boring data. In the lower display area of ​​the drilling data display section D3, the geological features can be displayed as bar graphs with different patterns, with the vertical axis representing depth (m) being filled in. The horizontal axis can represent intensity (dB), displaying the drilling sound intensity corresponding to the depth.

[0063] When the drilling head 6A reaches the support layer at the target drilling depth, it becomes visually apparent via the monitor image that the horizontal vibration amplitude increases, the integrated current value increases, and the vibration intensity of the drilling noise increases in response to the hard material.

[0064] The computer 40 that makes up the drilling support system 100 can also be configured as a cloud server on which the drilling support program is installed. By equipping terminals such as tablet computers with an API (Application Programming Interface), images can be shared among multiple terminals, and measurement start, stop, and display settings can be individually controlled on a terminal-by-terminal basis to the cloud server.

[0065] The embodiments described above represent only one aspect of the present invention, and the technical scope of the present invention is not limited by this description. It goes without saying that the specific configuration of each part can be appropriately modified and designed within the scope that achieves the effects of the present invention.
