Description

Technical Field

[0001] The present invention relates to a monitoring module, a measurement monitoring system, and a soil improvement status monitoring system.

Background Art

[0002] As one method of improving the ground, the deep mixing method is known. In a typical deep mixing method, for a ground that is inappropriately soft for the intended use, a soil-cement-based hard ground is improved by injecting a ground improvement material suitable for the soil quality and stirring and mixing the ground improvement material and the excavated soil while injecting the ground improvement material into the soft ground.

[0003] In the deep mixing method, when the viscosity of the soil to be improved is high, the soil to be improved may adhere to the stirring blade, and a co-rotation phenomenon may occur in which the stirring blade and the soil to be improved rotate integrally. When the co-rotation phenomenon occurs, the ground improvement material slurry and the soil to be improved cannot be sufficiently mixed, and the ground cannot be sufficiently improved.

[0004] Therefore, in order to prevent the co-rotation phenomenon, a ground improvement machine provided with a co-rotation prevention blade (shearing assist blade) has been proposed (see Patent Document 1). In the ground improvement machine of Patent Document 1, when the ground improvement blade where communication is difficult is underground, the co-rotation data is recorded in the memory of the device attached to the co-rotation prevention blade, so that the detection of the co-rotation of the co-rotation prevention blade and the collection of data are performed.

[0005] Furthermore, Patent Document 1 describes synchronizing or setting the clocks of the co-rotation evaluation control device, the ground improvement machine control device, and the co-rotation detection unit. In the ground improvement machine of Patent Document 1, when the start switch of the ground improvement machine control device is pressed by the operator, the clocks of the co-rotation evaluation control device, the ground improvement machine control device, and the co-rotation detection unit are synchronized or set. Subsequently, the co-rotation evaluation control device receives gyroscope data via a wireless module, and acquires necessary information such as the rotation speed of the mixing shaft, the amount of movement of the Z axis, and the amount of ground improvement material to be put in from the ground improvement machine control device. It then performs calculations from the obtained data and displays figures and tables on a display for the operator, construction manager, etc. [Prior art documents] [Patent Documents]

[0006] [Patent Document 1] Japanese Patent Publication No. 2025-036052 [Overview of the Initiative] [Problems that the invention aims to solve]

[0007] However, in the ground improvement machine described in Patent Document 1, it was sometimes not possible to fully grasp the state of the co-rotation of the anti-co-rotation blades. For example, if co-rotation occurs in a deep mixing treatment machine, the ground improvement piles may be re-installed. However, in the ground improvement machine described in Patent Document 1, the previous and subsequent installation statuses are compiled into separate data sets, and in order to check the progress of the previous and subsequent installation statuses, it was necessary to output and compare the separate data sets.

[0008] The present invention has been made in view of the above problems, and its purpose is to provide a monitoring module, a measurement and monitoring system, and a soil improvement status monitoring system that can appropriately grasp the soil conditions for a specific ground improvement pile. [Means for solving the problem]

[0009] The soil improvement status monitoring system of the present invention comprises a deep mixing construction machine that constructs ground improvement piles by performing deep mixing treatment on the ground, and a monitoring module that monitors the soil improvement status by the deep mixing construction machine, wherein the monitoring module stores as machine data a first time that is sequentially updated by a first time update unit and the detection results for the detection parameters of the deep mixing construction machine at the first time, and the deep mixing construction machine The machine data for the construction period during which the ground improvement piles are installed is associated with an identifier for identifying the ground improvement piles, the measurement module sequentially stores the second time, which is updated by the second time update unit, and the number of rotations per unit time of the shearing auxiliary blade at the second time as co-rotation data, the monitoring module receives the co-rotation data stored in the measurement module, the monitoring module extracts specific machine data from the machine data that is stored for different periods and associated with a common identifier among the identifiers, and the monitoring module generates combined data by combining multiple combined data sets that link the specific machine data and the co-rotation data, based on the first time of the specific machine data and the second time of the co-rotation data.

[0010] The measurement and monitoring system of the present invention is a deep mixing construction machine that constructs ground improvement piles by performing deep mixing treatment on the ground, and has a rotating rod, an excavation blade fixedly attached to the rotating rod, a stirring blade fixedly attached to the rotating rod, and a shearing auxiliary blade rotatably attached to the rotating rod, and comprises a measurement module attached to the shearing auxiliary blade and a monitoring module that monitors the soil improvement status by the deep mixing construction machine, wherein the monitoring module stores as machine data a first time that is sequentially updated by a first time update unit and the detection results for the detection parameters of the deep mixing construction machine at the first time, and also monitors the deep mixing construction machine The machine data for the construction period during which the ground improvement piles are installed is associated with an identifier for identifying the ground improvement piles, the measurement module sequentially stores the second time, which is updated by the second time update unit, and the number of rotations per unit time of the shearing auxiliary blade at the second time as co-rotation data, the monitoring module receives the co-rotation data stored in the measurement module, the monitoring module extracts specific machine data from the machine data that is stored for different periods and associated with a common identifier among the identifiers, and the monitoring module generates combined data by combining multiple combined data sets that link the specific machine data and the co-rotation data, based on the first time of the specific machine data and the second time of the co-rotation data.

[0011] The present invention provides a monitoring module for monitoring the soil improvement status when a deep mixing construction machine, which has a rotating rod, a drilling blade fixedly attached to the rotating rod, a stirring blade fixedly attached to the rotating rod, a shearing auxiliary blade rotatably attached to the rotating rod, and a measuring module attached to the shearing auxiliary blade, performs deep mixing on the ground to construct ground improvement piles. The monitoring module stores the first time, which is sequentially updated by the first time update unit, and the detection results for the detection parameters of the deep mixing construction machine at the first time as machine data in chronological order, and the deep mixing construction machine The machine data for the construction period during which the ground improvement piles are installed by the construction machine is associated with an identifier for identifying the ground improvement piles. The measurement module receives co-rotation data that is stored chronologically, which includes a second time point that is sequentially updated by a second time update unit and the number of rotations per unit time of the shearing auxiliary blades at the second time point. From the machine data, specific machine data stored for different periods and associated with a common identifier is extracted. Based on the first time point of the specific machine data and the second time point of the co-rotation data, combined data is generated by combining multiple combined data sets that link the specific machine data and the co-rotation data. [Effects of the Invention]

[0012] According to the present invention, a soil improvement status monitoring system can be provided that can appropriately grasp the soil improvement status for a specific ground improvement pile. [Brief explanation of the drawing]

[0014] Embodiments of the monitoring module, measurement monitoring system, and soil improvement status monitoring system according to the present invention will be described below with reference to the drawings. In the drawings, the same or corresponding parts are denoted by the same reference numerals and will not be repeated in the description. In this specification, mutually orthogonal X, Y, and Z axes may be described to facilitate understanding of the invention. Typically, the X and Y axes are parallel to the horizontal direction, and the Z axis is parallel to the vertical direction.

[0015] First, the soil improvement status monitoring system 10 of this embodiment will be described with reference to Figure 1. Figure 1 is a schematic diagram of the soil improvement status monitoring system 10 of this embodiment. The soil improvement status monitoring system 10 improves the soil quality of the ground and monitors the status of soil improvement.

[0016] As shown in FIG. 1, the soil improvement status monitoring system 10 includes a deep mixing treatment construction machine 100 and a monitoring module 60. The deep mixing treatment construction machine 100 forms improved soil piles by performing deep mixing treatment on the ground.

[0017] The monitoring module 60 monitors the operating status of the deep mixing treatment construction machine 100. In addition, the monitoring module 60 monitors the status of the improved soil piles formed by the deep mixing treatment construction machine 100. In one example, the monitoring module 60 is a so-called personal computer, tablet terminal, or smartphone.

[0018] The deep mixing treatment construction machine 100 is controlled to form improved soil piles by performing deep mixing treatment on the ground. Note that the monitoring module 60 may control the deep mixing treatment construction machine 100 based on the detection result of the detection device 20.

[0019] The soil improvement status monitoring system 10 may further include a detection device 20. The detection device 20 detects detection parameters related to the deep mixing treatment by the deep mixing treatment construction machine 100. Typically, the detection result detected by the detection device 20 is used for monitoring the deep mixing treatment construction machine 100. For example, the deep mixing treatment construction machine 100 is controlled based on the detection result detected by the detection device 20.

[0020] The deep mixing treatment construction machine 100 includes a rotating rod 110, a cutting blade 120, a stirring blade 130, a shear assisting blade 140, a housing 150, and a measurement module 160.

[0021] The rotating rod 110 rotates with respect to the rotation axis Rx. The rotating rod 110 extends in the rotation axis direction Rd (Z direction) in which the rotation axis Rx extends. An auger motor (not shown) is attached to the rotating rod 110. When the auger motor rotates and drives, the rotating rod 110 rotates with respect to the rotation axis Rx.

[0022] The rotating rod 110 has a substantially cylindrical rod body 112 and a substantially bottomed cylindrical head 114 that is coaxially connected to the lower end of the rod body 112. On the outer circumferential surface of the head 114, protrusions 114s and 114t are provided at predetermined intervals. The protrusions 114s and 114t extend circumferentially along the outer circumferential surface of the head 114. An auger motor or the like that rotates is attached to the rod body 112.

[0023] Inside the rotating rod 110, there is a channel for the ground improvement material (not shown in the diagram) that communicates with a discharge port 110h located at the lower end of the rotating rod 110. Typically, the ground improvement material is a cement-based slurry. In one example, the ground improvement material is prepared by mixing a geological cement-based solidifying agent with water. The ground improvement material is fed from the ground to the tip of the rotating rod 110 via the channel and discharged from the discharge port 110h onto the soil to be improved.

[0024] The excavation blade 120 is fixedly attached to the tip of the head portion 114 so as to protrude substantially horizontally from the tip of the head portion 114. The excavation blade 120 excavates soil by rotating integrally with the rotating rod 110. For example, the excavation blade 120 is driven to rotate clockwise integrally with the rotating rod 110, which is driven to rotate clockwise.

[0025] The mixing blade 130 is fixedly attached to the head portion 114 so as to protrude substantially horizontally from the head portion 114 above the excavation blade 120. Like the excavation blade 120, the mixing blade 130 rotates integrally with the rotating rod 110, thereby agitating and mixing the target soil excavated by the excavation blade 120 with the ground improvement material supplied to the target soil from the discharge port 110h at the lower end of the rotating rod 110. For example, the mixing blade 130 is driven to rotate clockwise integrally with the rotating rod 110, which is driven to rotate clockwise. The mixing blade 130 may protrude in a direction different from that of the excavation blade 120 relative to the rotating rod 110. For example, the mixing blade 130 may protrude in a direction perpendicular to that of the excavation blade 120 relative to the rotating rod 110.

[0026] The shearing auxiliary wing 140 is positioned between the excavation blade 120 and the mixing blade 130. For example, the shearing auxiliary wing 140 is loosely fitted or inserted into the head portion 114 and rotatably mounted by combining a +Y direction component and a -Y direction component toward the outer circumferential surface between the projections 114s and 114t of the head portion 114. The shearing auxiliary wing 140 assists in the stirring and mixing of the target soil and the ground improvement material by remaining stationary relative to the rotating rod 110, which is being driven to rotate, and prevents the target soil from adhering in clumps to the excavation blade 120 or the mixing blade 130 or both and rotating together with them. For example, because the shearing auxiliary wing 140 is stationary, the shearing auxiliary wing 140 rotates counterclockwise relative to the excavated soil and ground improvement material, which rotate clockwise as the rotating rod 110, excavation blade 120, and mixing blade 130 rotate in conjunction clockwise. However, the shearing auxiliary blade 140 may also rotate together with the excavation blade 120 or the agitation blade 130 or both, as the target soil may adhere to them in clumps.

[0027] Here, the radial length of the shearing auxiliary blade 140 is greater than the radial lengths of the excavating blade 120 and the stirring blade 130, respectively.

[0028] Multiple sets of stirring blades 130 and shearing auxiliary blades 140, which are spaced apart in the rotation axis direction Rd of the rotating rod 110, may be alternately attached to the head portion 114, which is also spaced apart in the rotation axis direction Rd of the rotating rod 110.

[0029] The housing 150 is attached to the base of the shear aileron 140. The housing 150 extends parallel to the shear aileron 140. The housing 150 has a hollow shape.

[0030] The measurement module 160 is housed in the housing 150. The measurement module 160 measures the condition of the ground improvement piles formed by the deep mixing construction machine 100. The measurement module 160 transmits the measurement results externally. For example, the measurement module 160 measures the number of rotations per unit time (rotational speed) of the shearing auxiliary blade 140 and transmits the measurement results to the monitoring module 60.

[0031] The housing 150 is constructed of a robust material such as stainless steel to protect the measurement module 160. The housing 150 is configured to allow access to the internal space of the box by removing the lid from the box. A sealing member is placed between the box and the lid to prevent water and soil from entering the internal space of the housing 150. For example, the sealing member is made of rubber with relatively high electromagnetic wave permeability. Because the sealing member is made of a material with high electromagnetic wave permeability, the housing 150 is configured to enable wireless communication between the internal space and the external space through the sealing member, which is deformed in the gap between the box and the lid.

[0032] The measurement module 160, along with its housing, has been miniaturized as much as possible by miniaturizing and / or arranging its components in close proximity, reducing wiring, etc., and is incorporated in a form that is housed in a recess formed at the base of the shearing auxiliary wing 140.

[0033] The detection device 20 is positioned on the ground at a suitable location around the rotating rod 110. The detection device 20 detects detection parameters related to the deep mixing process performed by the deep mixing process machine 100. For example, the detection device 20 detects the depth of the rotating rod 110, the number of rotations per unit time (rotational speed) of the rotating rod 110, the torque of the rotating rod 110, and the flow rate of the ground improvement material discharged from the discharge port 110h.

[0034] The monitoring module 60 is positioned on the ground at a suitable location around the rotating rod 110. The monitoring module 60 receives the detection results from the detection device 20 directly or indirectly. For example, the monitoring module 60 obtains the depth of the rotating rod 110, the rotations and torque per unit time, and the flow rate of the ground improvement material as detection results from the detection device 20. Based on the detection results from the detection device 20 and the measurement results from the measurement module 160, the monitoring module 60 monitors the condition of the ground improvement piles formed by the deep mixing construction machine 100.

[0035] In the soil improvement status monitoring system 10 of this embodiment, the target soil is excavated by the drilling blade 120 rotating integrally with the rotating rod 110. Furthermore, the ground improvement material is discharged onto the target soil from the discharge port 110h at the lower end of the rotating rod 110, and the agitation blade 130 rotates together with the rotating rod 110, thereby agitating and mixing the excavated soil and the ground improvement material. In addition, while the agitation blade 130 is rotating, the shearing auxiliary blade 140 remains stationary relative to the rotating rod 110 due to the resistance of the surrounding ground, thereby suppressing co-rotation and promoting the agitation and mixing of the excavated soil and the ground improvement material.

[0036] As mentioned above, the shearing auxiliary wing 140 is rotatably attached to the rotating rod 110. Ideally, even when the rotating rod 110 is driven to rotate, the shearing auxiliary wing 140 is stationary, and its rotational speed is 0 or nearly 0. On the other hand, if the rotational force of the rotating rod 110 is indirectly transmitted to the shearing auxiliary wing 140 by the clumps of target soil attached to the rotating rod 110 and the shearing auxiliary wing 140, the rotational speed of the shearing auxiliary wing 140 may become close to the rotational speed of the rotating rod 110. A relatively high rotational speed of the shearing auxiliary wing 140 indicates a high possibility that the shearing auxiliary wing 140 is rotating together with the machine, suggesting that the construction of the ground improvement pile by the deep mixing treatment construction machine 100 is insufficient. In this case, it is preferable for the deep mixing treatment construction machine 100 to re-construct the ground improvement pile.

[0037] Next, with reference to Figures 1 and 2, the deep mixing treatment machine 100 in the soil improvement status monitoring system 10 of this embodiment will be described. Figure 2 is a cross-sectional view of the deep mixing treatment machine 100 along the line II-II in Figure 1.

[0038] As shown in Figure 2, the drilling blade 120, stirring blade 130, and shearing auxiliary blade 140 extend in a direction perpendicular to the rotating rod 110, which extends in the rotation axis direction Rd (horizontal direction). The drilling blade 120 and stirring blade 130 extend in directions perpendicular to each other.

[0039] As described above, the drilling blade 120 rotates integrally with the rotary rod 110, which is rotationally driven, in the circumferential direction Cd. For example, the drilling blade 120 rotates integrally with the rotary rod 110, which is rotationally driven clockwise, in a clockwise direction.

[0040] The stirring blade 130, like the drilling blade 120, rotates integrally with the rotary rod 110, which is driven to rotate in the circumferential direction Cd. For example, the stirring blade 130 rotates integrally with the rotary rod 110, which is driven to rotate in a clockwise direction.

[0041] The shearing auxiliary blade 140 rotates independently of the rotating rod 110. For example, the shearing auxiliary blade 140 is stationary relative to the rotating rod 110, which is driven to rotate clockwise. In this case, the shearing auxiliary blade 140 rotates counterclockwise relative to the excavated soil and ground improvement material, which rotate clockwise as the rotating rod 110, stirring blade 130, and shearing auxiliary blade 140 rotate in conjunction clockwise.

[0042] Furthermore, by driving the rotating rod 110 to rotate counterclockwise through a predetermined operation, both the drilling blade 120 and the stirring blade 130 may rotate counterclockwise.

[0043] The rotating rod 110 extends in the vertical direction. The rotating rod 110 is rotationally driven by an auger motor.

[0044] The drilling blades 120 and agitation blades 130 are directly or indirectly connected to the rotating rod 110, and rotate as the rotating rod 110 is rotationally driven. For example, the drilling blades 120 and agitation blades 130 rotate when the auger motor rotationally drives the rotating rod 110. On the other hand, the shearing auxiliary blades 140 are mounted between projections 114s and 114t of the rotating rod 110, and the shearing auxiliary blades 140 can rotate relative to the rotating rod 110.

[0045] Next, with reference to Figure 3, the ground improvement piles A-1 to A-3 formed by the soil improvement status monitoring system 10 of this embodiment will be described. Figure 3 is a schematic diagram showing the ground improvement piles A-1 to A-3 formed by the soil improvement status monitoring system 10 of this embodiment.

[0046] As shown in Figure 3, typically, multiple ground improvement piles are formed at a single construction site. Ground improvement piles are pile-shaped improved bodies formed in the ground by the deep mixing treatment construction machine 100.

[0047] Here, the multiple ground improvement piles include ground improvement piles A-1 to A-3. Ground improvement piles A-1 to A-3 represent different ground improvement piles from each other. In Figure 3, ground improvement piles A-1 to A-3 are arranged at predetermined intervals, but ground improvement piles A-1 to A-3 may also be arranged adjacent to each other.

[0048] Each of the ground improvement piles A-1 to A-3 is formed by the deep mixing construction machine 100 described above. However, when the deep mixing construction machine 100 constructs ground improvement pile A-1, co-rotation may occur.

[0049] In Figure 3, areas where co-rotation occurred in ground improvement piles A-1 to A-3 are shaded, with finer shading indicating areas where co-rotation occurred more frequently. Here, it is shown that in ground improvement pile A-1, co-rotation occurred at a position deeper than the center of the pile, and more co-rotation occurred at a position higher than the center. Furthermore, it is shown that in ground improvement pile A-2, co-rotation occurred at a position deeper than the center of the pile. When co-rotation occurs during the formation of ground improvement piles in this manner, it is preferable for the deep mixing treatment machine 100 to perform the treatment multiple times for ground improvement piles A-1 and A-2 until co-rotation no longer occurs.

[0050] Next, the soil improvement status monitoring system 10 of this embodiment will be described with reference to Figure 4. Figure 4 is a block diagram of the soil improvement status monitoring system 10 of this embodiment.

[0051] As shown in Figure 4, the soil improvement status monitoring system 10 comprises a detection device 20, a monitoring module 60, and a measurement module 160.

[0052] As described above, the detection device 20 detects detection parameters related to the deep mixing process performed by the deep mixing process machine 100. For example, the detection parameters include the depth of the rotating rod 110, the number of rotations per unit time (rotational speed) of the rotating rod 110, the torque of the rotating rod 110, and the flow rate of the ground improvement material.

[0053] Here, the detection device 20 includes a depth detection device 21 for detecting the depth of the rotating rod 110, a rotation speed detection device 22 for detecting the number of rotations per unit time (rotational speed) of the rotating rod 110, a torque detection device 23 for detecting the torque of the rotating rod 110, and a flow rate detection device 24 for detecting the flow rate of the ground improvement material.

[0054] The depth detection device 21 detects the vertical movement distance of the auger motor attached to the rotating rod 110 using a Z-axis pulse encoder. The Z-axis pulse encoder detects the position of the drilling blade 120 by detecting the vertical movement distance of the auger motor on the leader. For example, the Z-axis pulse encoder detects the rotational speed of a chain-driven sprocket.

[0055] The rotational speed detection device 22 detects the rotational speed of the hydraulic motor mounted on the auger motor that drives the rotating rod 110. For example, the pulse encoder detects the rotational speed of the output shaft of the hydraulic motor. This pulse encoder can detect the rotational speed of the rotating rod 110, which is mechanically connected to the output shaft of the hydraulic motor via a reduction gear.

[0056] The torque detection device 23 measures the pressure resistance or current value of the hydraulic or electric motor or the hydraulic pressure of the earth auger that drives the auger motor, and detects the rotational torque (torsional moment) acting on the rotating rod 110.

[0057] The flow detection device 24 uses a flow meter to detect the discharge flow rate of the ground improvement material. In the deep mixing treatment construction machine 100, when forming ground improvement piles, the ground improvement material in the ground improvement material tank is sucked in by a motor-driven pressure pump, pressurized, and sent to the top of the rotating rod 110. The flow meter can detect the flow rate per unit time when the ground improvement material is sent by the pump.

[0058] Typically, the operator of the deep mixing treatment machine 100 checks the detection results detected by the detection device 20. For example, the operator checks the detection results detected by the detection device 20 via the monitoring module 60. The operator controls the operation of the deep mixing treatment machine 100 based on the detection results.

[0059] The deep mixing machine 100 may be automatically controlled based on the detection results detected by the detection device 20. In this case, the monitoring module 60 may control the deep mixing machine 100 based on the detection results, or a module other than the monitoring module 60 may control the deep mixing machine 100 based on the detection results.

[0060] The monitoring module 60 is positioned on the ground at a suitable location around the deep mixing treatment machine 100. The monitoring module 60 is connected directly or indirectly to the detection device 20. When the monitoring module 60 obtains detection results from the detection device 20, it saves the detection results. For example, the monitoring module 60 updates the time sequentially and saves the detection results along with the time of detection.

[0061] The measurement module 160 measures the rotational speed per unit time of the shear aid vane 140 and saves the measurement results. For example, the measurement module 160 updates the time sequentially and saves the measurement results along with the corresponding time.

[0062] In this specification, the time that the monitoring module 60 updates sequentially may be referred to as the first time. The monitoring module 60 stores the first time and the detection result of the detection device 20 corresponding to the first time together as machine data. More specifically, the monitoring module 60 stores the first time and the detection result of the detection device 20 chronologically as machine data.

[0063] Furthermore, in this specification, the time that the measurement module 160 updates sequentially may be referred to as the second time. The measurement module 160 stores the second time and the measurement result corresponding to the second time (rotational speed of the shear aid vane 140) together as co-rotation data. In detail, the measurement module 160 stores the rotational speed of the shear aid vane 140 together with the second time as co-rotation data in chronological order.

[0064] The monitoring module 60 comprises a control unit 61, a storage unit 62, a wireless communication device 63, a first time update unit 64, an input interface 65, and an output interface 66. The control unit 61 controls the storage unit 62, the wireless communication device 63, the input interface 65, and the output interface 66.

[0065] The control unit 61 is composed of arithmetic processing units (CPU, single-core processor, multi-core processor) that make up the computer.

[0066] The storage unit 62 is composed of an HDD, SSD, or memory (RAM, ROM, etc.). The storage unit 62 stores data received through the wireless communication device 63. The storage unit 62 may also store data received through devices other than the wireless communication device 63.

[0067] The wireless communication device 63 is composed of wireless communication equipment using the same wireless communication method as the measurement module 160. The wireless communication device 63 communicates wirelessly with the measurement module 160. For example, the wireless communication device 63 transmits signals to the measurement module 160. The wireless communication device 63 also receives co-rotation data transmitted from the measurement module 160. If wireless communication between the wireless communication device 63 and the measurement module 160 is difficult, the co-rotation data stored in the measurement module 160 may be transferred to the monitoring module 60 via a storage medium. In this way, the monitoring module 60 may receive the co-rotation data stored in the measurement module 160 directly or indirectly from the measurement module 160.

[0068] The input interface 65 receives instructions from the operator. The control unit 61 controls various components according to the operator's instructions received via the input interface 65.

[0069] The input interface 65 consists of buttons, a keyboard, and a touch-panel display. The operator may input via contact operation through the input interface 65. Alternatively, the input interface 65 consists of a microphone. The operator may input via non-contact operation by speaking through the input interface 65.

[0070] The output interface 66 outputs detection results and data to the operator. For example, the output interface 66 is configured by an image display device (monitor). Alternatively, the output interface 66 may be configured by an audio output device (speaker), or it may be configured by both an image display device (monitor) and an audio output device (speaker).

[0071] The control unit 61, storage unit 62, wireless communication device 63, input interface 65, and output interface 66 may each be powered by either the battery built into the monitoring module 60 or by commercial power.

[0072] The monitoring module 60 may be able to communicate with devices other than the measurement module 160 via wireless communication equipment 63 or other equipment. For example, the monitoring module 60 may receive detection results from the detection device 20 via wireless or wired communication. Alternatively, the monitoring module 60 may receive data from devices other than the deep mixing process machine 100. For example, the monitoring module 60 may receive data from external devices via the Internet.

[0073] The first time update unit 64 updates the first time sequentially. The first time update unit 64 may be an integrated circuit. The first time updated by the first time update unit 64 may be appropriately modified according to the time obtained from an external device via the Internet.

[0074] The control unit 61 receives the detection result from the detection device 20 and stores the machine data, including the first time updated by the first time update unit 64 and the detection result corresponding to the first time, in chronological order in the storage unit 62.

[0075] The measurement module 160 comprises a control unit 161, a storage unit 162, a wireless communication device 163, a second time update unit 164, a monitoring sensor 165, and a battery 166. The control unit 161 controls the storage unit 162, the wireless communication device 163, the monitoring sensor 165, and the battery 166.

[0076] The control unit 161 is composed of arithmetic processing units (CPU, single-core processor, multi-core processor) that make up the computer.

[0077] The storage unit 162 is composed of an HDD, SSD, or memory (RAM, ROM, etc.). The storage unit 162 stores the output signal of the monitoring sensor 165 or the rotation speed of the shearing auxiliary blade 140 represented by said output signal in a time series.

[0078] The wireless communication device 163 is comprised of, for example, a short-range wireless communication device (e.g., Bluetooth ("Bluetooth" is a registered trademark)) or a long-range wireless communication device (e.g., Wi-Fi ("Wi-Fi" is a registered trademark)).

[0079] Wireless communication device 163 is composed of wireless communication devices that use the same wireless communication method as wireless communication device 63. For example, wireless communication device 163 communicates wirelessly with wireless communication device 63. For example, wireless communication device 163 receives signals transmitted from wireless communication device 63. Also, wireless communication device 163 transmits data to wireless communication device 63.

[0080] The second time update unit 164 sequentially updates the second time. The second time update unit 164 may be an integrated circuit. The second time updated by the second time update unit 164 may be appropriately modified according to the first time obtained from the monitoring module 60.

[0081] The monitoring sensor 165 measures the number of rotations per unit time (rotational speed) of the shear aileron 140. For example, the monitoring sensor 165 consists of a gyro sensor, a magnetic sensor, and / or a geomagnetic sensor for measuring the rotational speed of the shear aileron 140 in a world coordinate system. For example, the monitoring sensor 165 measures the number of rotations per unit time (rotational speed) of the shear aileron 140 relative to a stationary object.

[0082] Furthermore, the monitoring sensor 165 may be configured such that a magnetic proximity switch positioned close to the shearing auxiliary blade 140 on the rotationally driven rotating rod 110 detects one or more magnets positioned circumferentially on the shearing auxiliary blade 140 at a position radially away from the rotation axis Rx. In this case, the proximity of the magnets and the magnetic proximity switch allows for the measurement of the relative rotation speed of the shearing auxiliary blade 140 with respect to the rotationally driven rotating rod 110 in a non-contact manner. Thus, the monitoring sensor 165 may measure the rotation speed (rotational velocity) of the shearing auxiliary blade 140 per unit time with respect to the rotationally driven rotating rod 110.

[0083] In the measurement module 160, the control unit 161 acquires sensor data representing the number of rotations per unit time (rotational speed) of the shearing auxiliary blade 140 via the monitoring sensor 165, and stores the rotational speed of the shearing auxiliary blade 140 as co-rotation data in the storage unit 162 in a time series along with a second time that is sequentially updated by the second time update unit 164. The co-rotation data stored in the storage unit 162 is transmitted to the monitoring module 60 at a predetermined timing.

[0084] The battery 166 supplies power to the control unit 161, the memory unit 162, the wireless communication device 163, and the monitoring sensor 165. The battery 166 may function as a common power source for each of the control unit 161, the memory unit 162, the wireless communication device 163, and the monitoring sensor 165, or it may function as a separate power source for each of them.

[0085] The control unit 161 detects the remaining charge of the battery 166. The control unit 161 stores the remaining charge of the battery in chronological order in the storage unit 162.

[0086] In this specification, the monitoring module 60 and the measurement module 160, which communicate with each other, may be collectively referred to as the measurement and monitoring system 50. As described above, the monitoring module 60 and the measurement module 160 are capable of communicating with each other. The monitoring module 60 and the measurement module 160 may be removed from one soil improvement status monitoring system 10 and / or deep mixing treatment machine 100 and installed in another soil improvement status monitoring system 10 and / or deep mixing treatment machine 100 for use.

[0087] Typically, the measuring module 160 is housed in a housing 150 attached to a shearing auxiliary vane 140 that can rotate by co-rotation. Typically, the performance of the control unit 161 is lower than that of the control unit 61, and the functions that can be realized by the control unit 161 are more limited than those that can be realized by the control unit 61.

[0088] Next, with reference to Figures 5A and 5B, the construction flow of ground improvement piles using the soil improvement status monitoring system 10 of this embodiment will be described. Figures 5A and 5B are flowcharts showing the construction flow of ground improvement piles using the soil improvement status monitoring system 10 of this embodiment.

[0089] As shown in Figure 5A, in step S101, the control unit 61 starts saving the detection results of the detection device 20 as machine data in the storage unit 62 in chronological order, along with the first time, which is updated sequentially.

[0090] In detail, the control unit 61 drives the detection device 20 (Figures 1 and 4) to receive detection results from the detection device 20. For example, the control unit 61 receives results from the detection device 20 that include the depth of the rotating rod 110, the rotations of the rotating rod 110 per unit time, the torque of the rotating rod 110, and the flow rate of the ground improvement material discharged from the discharge port 110h. The control unit 61 stores the detection results from the detection device 20 as machine data in the storage unit 62 in chronological order along with a first time point that is updated sequentially. The monitoring module 60 proceeds to step S102.

[0091] In step S102, the monitoring module 60 transmits first time data indicating the first time to the measurement module 160. More specifically, under the control of the control unit 61, the wireless communication device 63 transmits the first time data to the wireless communication device 163. The monitoring module 60 then proceeds to step S112.

[0092] In step S201, the control unit 161 stores battery data indicating the remaining battery level in the storage unit 162 in chronological order along with a second time point that is updated sequentially. The processing of the measurement module 160 proceeds to step S202.

[0093] In step S202, the control unit 161 determines whether or not it has received the first time data from the monitoring module 60. More specifically, the control unit 161 determines whether or not the wireless communication device 163 has received the first time data from the wireless communication device 63.

[0094] If the first time data is received (if the answer is YES in step S202), the measurement module 160 proceeds to step S204. If the first time data is not received (if the answer is NO in step S202), the measurement module 160 proceeds to step S212.

[0095] In step S204, the control unit 161 determines whether there is a discrepancy between the first time indicated in the first time data received from the monitoring module 60 and the second time being updated by the second time update unit 164.

[0096] If there is a discrepancy between the first time and the second time (if the answer is YES in step S204), the measurement module 160 proceeds to step S206. If there is no discrepancy between the first time and the second time (if the answer is NO in step S204), the measurement module 160 proceeds to step S212.

[0097] In step S206, the control unit 161 adjusts the second time being updated by the second time update unit 164 to match the first time indicated in the first time data received from the monitoring module 60. As a result, the second time being updated by the second time update unit 164 matches the first time being updated by the monitoring module 60. After that, the processing of the measurement module 160 proceeds to step S212.

[0098] In step S112, the control unit 61 determines whether or not to start construction of the ground improvement piles. For example, the control unit 61 determines whether or not the operator has input an instruction to start construction via the input interface 65. Alternatively, the control unit 61 determines whether or not the start time of the construction schedule pre-set in the storage unit 62 or other storage device has arrived.

[0099] If construction of ground improvement piles is to be started (if the answer is YES in step S112), the monitoring module 60 proceeds to step S114. If construction of ground improvement piles is not to be started (if the answer is NO in step S112), the monitoring module 60 returns to step S102.

[0100] In step S114, a pile number is set, which is an identifier for identifying the ground improvement pile that the deep mixing treatment machine 100 is targeting for this construction. Typically, the pile number indicates an identification number that identifies the ground improvement pile that the deep mixing treatment machine 100 will improve the soil properties of in this construction in the ground target.

[0101] For example, the control unit 61 sets the pile number entered by the operator via the input interface 65 as the target for the current construction by the deep mixing construction machine 100. Alternatively, the pile number may be set by the Global Navigation Satellite System (GNSS). In this case, the pile number is sequentially added to machine data that is stored chronologically over the construction period for the current ground improvement pile.

[0102] The control unit 61 adds the stake number and continues to save the machine data in chronological order in the storage unit 62. In this case, the machine data saved chronologically in the storage unit 62 by the control unit 61 includes the first time, the detection result of the detection device 20, and the stake number.

[0103] In step S116, the monitoring module 60 transmits a construction start command signal to the measurement module 160. Specifically, under the control of the control unit 61, the wireless communication device 63 transmits a construction start command signal to the wireless communication device 163. Subsequently, the control unit 61 starts the construction of the ground improvement piles. Specifically, the control unit 61 starts rotating the rotating rod 110 and begins excavating the target soil. The control unit 61 also discharges the ground improvement material at a predetermined timing. The monitoring module 60 then proceeds to step S122.

[0104] In step S212, the control unit 161 determines whether or not it has received a construction start command signal. More specifically, the control unit 161 determines whether or not the wireless communication device 163 has received a construction start command signal from the wireless communication device 63.

[0105] If a construction start command signal is received (if the answer is YES in step S212), the measurement module 160 proceeds to step S214. If a construction start command signal is not received (if the answer is NO in step S212), the measurement module 160 returns to step S202.

[0106] In step S214, the control unit 161 starts saving the co-rotation data. The control unit 161 starts saving the sequentially updated second time and battery data as co-rotation data in the storage unit 162 in a time series. The processing of the measurement module 160 proceeds to step S222.

[0107] In step S122, the control unit 61 determines whether or not to stop the construction of the ground improvement piles. For example, the control unit 61 determines whether or not the operator has input an instruction to stop construction via the input interface 65. Alternatively, the control unit 61 determines whether or not the end time of the construction schedule pre-set in the storage unit 62 has arrived.

[0108] If the construction of the ground improvement piles is to be stopped (if the answer is YES in step S122), the monitoring module 60 proceeds to step S124. If the construction of the ground improvement piles is not to be stopped (if the answer is NO in step S122), the monitoring module 60 returns to step S122.

[0109] In step S124, the control unit 61 cancels the stake number setting. For example, the control unit 61 stops saving the stake number to the storage unit 62 and instead saves the first time and the machine data, which includes the detection result of the detection device 20 corresponding to the first time, in chronological order. In this way, the control unit 61 continues to save the detection result of the detection device 20 as machine data in the storage unit 62 without saving the stake number. Therefore, the machine data includes the stake number throughout the construction period, but does not include the stake number during periods other than the construction period. The monitoring module 60 proceeds to step S126.

[0110] In step S126, the monitoring module 60 transmits a stop command signal to the measurement module 160. Specifically, under the control of the control unit 61, the wireless communication device 63 transmits a stop command signal to the wireless communication device 163. The monitoring module 60 then proceeds to step S132.

[0111] In step S222, the control unit 161 determines whether or not it has received a stop command signal. More specifically, the control unit 161 determines whether or not the wireless communication device 163 has received a stop command signal from the wireless communication device 63.

[0112] If a stop command signal is received (if the answer is YES in step S222), the measurement module 160 proceeds to step S224. If a stop command signal is not received (if the answer is NO in step S222), the measurement module 160 returns to step S214.

[0113] In step S224, the control unit 161 stops saving the co-rotation data. Alternatively, the control unit 161 may input a value of 0 as the co-rotation data along with the sequentially updated second time and battery data. The processing of the measurement module 160 proceeds to step S232.

[0114] As shown in Figure 5B, in step S132, the monitoring module 60 transmits a data transfer signal to the measurement module 160. More specifically, under the control of the control unit 61, the wireless communication device 63 transmits a data transfer signal to the wireless communication device 163. The monitoring module 60 then proceeds to step S134.

[0115] In step S232, the control unit 161 determines whether or not it has received a data transfer signal. More specifically, the control unit 161 determines whether or not the wireless communication device 163 has received a data transfer signal from the wireless communication device 63.

[0116] If a data transfer signal is received (if the answer is YES in step S232), the measurement module 160 proceeds to step S234. If a data transfer signal is not received (if the answer is NO in step S232), the measurement module 160 returns to step S232.

[0117] In step S234, the measurement module 160 transmits the co-rotation data to the monitoring module 60. More specifically, under the control of the control unit 161, the wireless communication device 163 transmits the co-rotation data to the wireless communication device 63. The processing of the measurement module 160 proceeds to step S242.

[0118] In step S134, the control unit 61 determines whether or not it has received co-circulation data. More specifically, the control unit 61 determines whether or not the wireless communication device 63 has received co-circulation data from the wireless communication device 163.

[0119] If co-circulation data is received (if YES in step S134), the monitoring module 60 proceeds to step S136. If co-circulation data is not received (if NO in step S134), the monitoring module 60 returns to step S134.

[0120] In step S136, the control unit 61 extracts a portion of the machine data and combines it with the co-rotation data to generate combined data. Specifically, the control unit 61 searches for specific machine data indicating a specific stake number from the machine data in the storage unit 62 and extracts it as specific machine data. Then, based on the first time of the specific machine data and the second time of the co-rotation data received from the measurement module 160, the control unit 61 forms multiple linked data sets by linking the specific machine data and the co-rotation data, and generates combined data by combining these linked data sets. Typically, the control unit 61 extracts data from the co-rotation data that has the same second time as the first time of the specific machine data, forms multiple linked data sets by linking specific machine data and co-rotation data with the same time, and generates combined data by combining these linked data sets. Note that the first time of the specific machine data and the second time of the co-rotation data do not necessarily have to be the same, and there may be a difference within a predetermined range. The monitoring module 60 proceeds to step S142.

[0121] In step S142, the monitoring module 60 outputs combined data. For example, the control unit 61 controls the output interface 66 so that it displays or outputs audio according to the combined data. Alternatively, the control unit 61 may control the output interface 66 so that the wireless communication device 63 or other communication means communicates the combined data externally. The monitoring module 60 proceeds to step S152.

[0122] In step S152, the control unit 61 determines whether or not to re-install the ground improvement piles. For example, the control unit 61 determines whether or not the operator has input an instruction to start re-installation via the input interface 65. In one example, if the operator determines from the display output according to the combined data that co-rotation occurred in the previous installation, an instruction to re-install the ground improvement piles is input from the operator to the input interface 65. The control unit 61 may also determine whether the results of the previous installation meet predetermined criteria. For example, the control unit 61 determines whether or not co-rotation occurred in the previous installation compared to predetermined criteria.

[0123] If the ground improvement piles are to be re-installed (if the answer is YES in step S152), the monitoring module 60 returns to step S112. If the ground improvement piles are to be re-installed, and the control unit 61 determines in step S112 to start the installation (re-installation) of the ground improvement piles, in step S114, the same pile number is set to identify the same ground improvement piles that are the target of the deep mixing construction machine 100's re-installation. In this case as well, the pile numbers are sequentially added to the machine data, which is saved chronologically over the re-installation period for the current ground improvement piles. Subsequently, if the installation of the ground improvement piles is to be stopped (if the answer is YES in step S122), in step S124, the control unit 61 cancels the setting of the pile number. For example, the control unit 61 stops saving the pile number to the storage unit 62.

[0124] Subsequently, if co-rotation data is received (if YES in step S134), in step S136, the control unit 61 extracts a portion of the machine data and combines it with the co-rotation data to generate combined data. Specifically, the control unit 61 searches for specific machine data indicating a common stake number from the machine data in the storage unit 62 and extracts it as specific machine data. Then, based on the first time of the specific machine data and the second time of the co-rotation data received from the measurement module 160, the control unit 61 forms multiple combined data sets by linking the specific machine data and the co-rotation data, and generates combined data by combining these combined data sets. Then, in step S142, the monitoring module 60 outputs the combined data.

[0125] If the ground improvement piles are not to be reinstalled (if the answer is NO in step S152), the monitoring module 60 proceeds to step S162.

[0126] In step S162, the control unit 61 determines whether or not to construct other ground improvement piles. For example, the control unit 61 determines whether or not the operator has input an instruction to construct other ground improvement piles via the input interface 65. Alternatively, the control unit 61 determines whether or not there is a plan to construct other ground improvement piles in the construction schedule pre-set in the storage unit 62.

[0127] If other ground improvement piles are to be installed (if the answer is YES in step S162), the monitoring module 60 returns to step S112. If other ground improvement piles are not to be installed (if the answer is NO in step S162), the monitoring module 60 proceeds to step S164.

[0128] In step S164, the control unit 61 terminates the saving of machine data. Subsequently, the monitoring module 60 terminates its processing.

[0129] In step S242, the control unit 161 determines whether or not to terminate the process. For example, the control unit 161 determines whether or not the operation of the monitoring module 60 has been stopped.

[0130] If the process is not terminated (the answer is NO in step S242), the process of the measurement module 160 returns to step S202. If the process is terminated (the answer is YES in step S242), the process of the measurement module 160 is terminated.

[0131] As described above, the soil improvement status monitoring system 10 of this embodiment executes the construction flow of ground improvement piles. According to the soil improvement status monitoring system 10 of this embodiment, before starting the construction of ground improvement piles, a pile number to identify the ground improvement pile is set, and the pile number is added to the machine data and saved. When stopping the construction of ground improvement piles, the setting of the pile number is canceled, and the saving of the pile number in the machine data is stopped. Furthermore, when reconstructing ground improvement piles, the same pile number to identify the same ground improvement pile is set before starting the reconstruction of the ground improvement piles, and the pile number is added to the machine data and saved. When stopping the reconstruction of the ground improvement piles, this setting of the pile number is canceled, and the saving of the pile number in the machine data is stopped. As a result, in the machine data, multiple linked data sets are created by linking specific machine data that extracts specific pile numbers saved over different periods with corresponding time-based data. This combined data allows for a simultaneous understanding of changes in soil conditions during different construction periods for the same ground improvement pile with the same identification number.

[0132] In the construction flow shown in Figures 5A and 5B, the measurement module 160 receives a data transfer signal from the monitoring module 60 and then transmits the co-rotation data to the monitoring module 60. However, the measurement module 160 and the monitoring module 60 may not be able to communicate, resulting in the measurement module 160 not receiving the data transfer signal, or the monitoring module 60 not receiving the co-rotation data from the measurement module 160. In this case, the co-rotation data stored in the measurement module 160 may be transferred to the monitoring module 60 via a storage medium. Thus, the monitoring module 60 may indirectly receive the co-rotation data stored in the measurement module 160 from the measurement module 160.

[0133] In the above description with reference to Figures 5A and 5B, the pile number set in step S114 was subsequently saved chronologically as part of the machine data, but this embodiment is not limited to this. The pile number only needs to be stored in association with the machine data during the construction period of the target ground improvement pile, and does not need to be saved chronologically as part of the machine data. For example, after the pile number is set in step S114, the machine data is saved chronologically in the storage unit 62 along with the detection results of the detection device 20, which are updated sequentially, and an identifier for identifying the ground improvement pile may be assigned once to the entire machine data during the construction period of the target ground improvement pile.

[0134] In this way, machine data for the ground improvement piles from the start to the end of the construction period is associated with an identifier for identifying the target ground improvement pile. As a result, by combining multiple linked data sets, which are created by linking specific machine data associated with a specific identifier with co-rotation data at a second time point corresponding to the first time point of the specific machine data, it is possible to understand the occurrence of co-rotation in relation to the operation status of the deep mixing construction machine 100 in the construction performed so far on the ground improvement piles identified by a specific identifier, and thus monitor changes in the soil improvement of the ground all at once.

[0135] Next, with reference to Figure 6, the machine data X and co-rotation data Y in the soil improvement status monitoring system 10 of this embodiment will be explained. Figure 6(a) is a schematic diagram showing the machine data X acquired by the monitoring module 60 and the co-rotation data Y acquired by the measurement module 160, and Figure 6(b) is a schematic diagram showing the combined data Z which is formed by combining multiple combined data Z1 and Z2, which are created by linking specific machine data X1 and X3 extracted from the machine data acquired by the monitoring module 60 with the corresponding co-rotation data Y1 and Y3 at the same time.

[0136] As shown in Figure 6(a), the first time point and the detection result of the detection device 20 are stored chronologically as machine data X. Furthermore, during the construction period of the ground improvement piles, the pile number is also added to the machine data X and stored chronologically. In this case, the detection result of the detection device 20 is the depth of the rotating rod 110, the rotations of the rotating rod 110 per unit time, the torque of the rotating rod 110, and the flow rate of the ground improvement material.

[0137] In Figure 6(a), machine data X includes machine data X0, X1, X2, X3, and X4. Machine data X0 shows the detection results before the start of construction of the ground improvement piles, machine data X1 shows the results during the construction period of the ground improvement piles, machine data X2 shows the results after the construction of the ground improvement piles was stopped, machine data X3 shows the results during the reconstruction period of the ground improvement piles, and machine data X4 shows the results after the reconstruction of the ground improvement piles was stopped. Here, the interval for saving the machine data chronologically is 1 second (sampling rate is 1 S / s).

[0138] Machine data X0, X2, and X4 are not data from the construction or reconstruction period of the ground improvement piles, but rather data from the period when the deep mixing treatment construction machine 100 was stopped. Therefore, the detection result of the detection device 20 is zero. On the other hand, machine data X1 and X3 are data from the construction or reconstruction period of the ground improvement piles, and the detection result of the detection device 20 is a predetermined value other than zero.

[0139] Note that machine data X0, X2, and X4 do not include the pile number because they are not data from the construction or reconstruction period of the ground improvement piles, and the setting for the target pile number is removed when the construction of the ground improvement piles is stopped. On the other hand, machine data X1 and X3 are data from the construction or reconstruction period of the ground improvement piles, and the target pile number is set, so they include the pile number.

[0140] Similarly, in Figure 6(a), the co-rotation data Y includes co-rotation data Y1, Y2, Y3, and Y4. Co-rotation data Y1 shows the results during the construction period of the ground improvement pile, and co-rotation data Y2 shows the results after the construction of the ground improvement pile was stopped. Co-rotation data Y3 shows the results during the re-construction period of the ground improvement pile, and co-rotation data Y4 shows the results after the re-construction of the ground improvement pile was stopped.

[0141] The co-rotation data Y2 and Y4 are not from the construction or re-construction period of the ground improvement pile, and the measurement results (rotation speed of the shear auxiliary wing 140) are both zero. On the other hand, the co-rotation data Y1 and Y3 are from the construction or re-construction period of the ground improvement pile. Here, the measurement result (rotation speed) of co-rotation during the construction period of the ground improvement pile was approximately 30, while the measurement result (rotation speed) of co-rotation during the re-construction period of the ground improvement pile was reduced to 0.

[0142] Note that while machine data X includes machine data X0 showing the results before construction of the ground improvement piles began, the measurement module 160 started saving the co-rotation data Y after receiving the construction start command signal, so the co-rotation data Y does not include data showing the results before construction of the ground improvement piles began.

[0143] Subsequently, as shown in Figure 6(b), the control unit 61 searches for machine data X1 and X3 stored in different periods that indicate a common stake number A-1 from the machine data X0 to X4 stored in the storage unit 62, and extracts them as specific machine data X1 and X3. Then, the control unit 61 extracts data Y1 and Y3 from the co-rotation data received from the measurement module 160 for the second time period corresponding to the first time period of the specific machine data X1 and X3. The control unit 61 generates concatenated data Z1 by concatenating the specific machine data X1 and the co-rotation data Y1. The control unit 61 also generates concatenated data Z2 by concatenating the specific machine data X3 and the co-rotation data Y3. Then, the control unit 61 generates combined data Z by combining the concatenated data Z1 and the concatenated data Z2.

[0144] Here, linked data Z1 shows the detection results and co-rotation status of the detection parameters of the deep mixing treatment machine 100 during the construction period of the ground improvement pile, and linked data Z2 shows the detection results and co-rotation status of the detection parameters of the deep mixing treatment machine 100 during the re-construction period of the ground improvement pile. Therefore, the combined data Z, which is a combination of linked data Z1 and Z2, shows the detection results and co-rotation status of the detection parameters of the deep mixing treatment machine 100 during the construction period and the re-construction period of the ground improvement pile.

[0145] According to the soil improvement status monitoring system 10 of this embodiment, combined data Z is generated by combining multiple combined data Z1 and Z2, which are created by linking specific machine data X1 and X3 that searched for a common pile number A-1 in machine data X0 to X4 with the corresponding time-based co-rotation data Y1 and Y3. Therefore, it is possible to grasp the changes in soil conditions during construction and re-construction for the same ground improvement pile with the same pile number identification number at once.

[0146] Next, with reference to Figure 7, the combined data generated in the soil improvement status monitoring system 10 of this embodiment will be explained. Figure 7 is a graph displaying the combined data generated in the soil improvement status monitoring system 10 of this embodiment.

[0147] As shown in Figure 7, the graph shows the detection results of the detection device 20 and the temporal change in the number of rotations per unit time of the shearing auxiliary blade 140. During the initial construction period for ground improvement pile A-1, the rotating rod 110 initially moves from the surface to deep underground while rotating at a predetermined number of rotations. In this process, the shearing auxiliary blade 140 rotates together with the rotating rod 110 at a relatively high number of rotations when the depth of the rotating rod 110 is around -5m to -8m. Subsequently, even in the process of the rotating rod 110 returning from underground to the surface, the shearing auxiliary blade 140 rotates together with the rotating rod 110 at a relatively high number of rotations when the depth of the rotating rod 110 is around -6m to -8m.

[0148] Subsequently, during the re-construction period for the ground improvement pile A-1, the rotating rod 110 of the deep mixing treatment machine 100 showed almost no co-rotation during the process of moving from the surface to deep underground and during the process of returning from underground to the surface.

[0149] According to the soil improvement status monitoring system 10 of this embodiment, the detection results of the deep mixing treatment construction machine 100 and the rotation status during construction and reconstruction of a specific ground improvement pile can be grasped at once, making it easy to determine whether further construction is necessary.
