Description

[Technical field]

[0001] The present invention relates to a measurement system. [Background technology]

[0002] The construction method of a cast-in-place concrete pile consists of an excavation process, a construction process, and a casting process. In the excavation process, a vertical hole is excavated in the ground. In the insertion process, reinforcing bars and, if necessary, steel pipes are inserted into the vertical hole. In the casting process, fresh concrete is poured into the vertical hole.

[0003] After the excavation process, it is necessary to inspect whether the completed shape of the shaft is as designed, and for example, an ultrasonic measuring device disclosed in Patent Document 1 is used to measure the completed shape of the shaft. This ultrasonic measuring device has an elevator installed above the shaft, a rope hanging from the elevator into the shaft, two ultrasonic transmitters and receivers attached to the lower end of the rope, and a recorder that prints the measurement results of the ultrasonic transmitters and receivers on a recording paper. The ultrasonic transmitters and receivers transmit ultrasonic waves toward the inner wall of the shaft and receive reflected waves from the inner wall to measure the distance to the inner wall. Two recording lines representing the measured distance are printed on the recording paper by the recorder. The recording lines on the recording paper represent the vertical cross-sectional shape of the inner wall of the shaft, and the distance between the two recording lines represents the diameter of the shaft. Patent Document 1 also discloses that four ultrasonic transmitters and receivers are attached to the lower end of the rope. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2002-243841 A Summary of the Invention [Problem to be solved by the invention]

[0005] However, if the completed pit information is only recorded on a recording sheet, it is inconvenient to manage and handle it. For example, the completed pit information recorded on the recording sheet cannot be easily shared, and furthermore, it is not easy to edit the completed pit information, such as by modifying, deleting, adding, or updating it. Therefore, an object of the present invention is to provide a measurement system that can conveniently manage and handle pit completion information. [Means for solving the problem]

[0013] Hereinafter, the embodiments will be described with reference to the drawings. The features and technical effects of the embodiments will be understood from the following detailed description and drawings. However, the scope of the present invention is not limited to the embodiments disclosed below. The drawings are provided for illustrative purposes only, and therefore the scope of the present invention is not limited to the illustrations in the drawings.

[0014] FIG. 1 is a diagram showing an outline of the measurement system.

[0015] In constructing a cast-in-place concrete pile, a pit 97 is excavated from the ground 98 almost vertically into the ground 99, and then a concrete pile or a steel pipe concrete pile such as an enlarged base pile or a straight pile is constructed in the pit 97. After the pit 97 is excavated and before the concrete pile or the steel pipe concrete pile is constructed, a measurement system is used to inspect the finished shape of the pit 97. An enlarged base pile is a pile in which the diameter of the part above the bottom of the pile is constant and the diameter of the bottom of the pile increases toward the bottom. A straight pile is a pile in which the diameter is constant over its entire length. In the following description, the pit 97 is used for an expanded bottom pile. In the pit 97, the part where the pile diameter is constant is called the fixed diameter part 97a, the part where the pile diameter increases downward is called the expanded diameter part 97b, and the part below the expanded diameter part 97b is called the rising part 97c. The diameter of the rising part 97c is almost constant. Of course, the pit 97 may be used for a straight pile, but in this case, the pit 97 does not have the expanded diameter part 97b and the rising part 97c, and the diameter of the pit 97 is constant over its entire length.

[0016] <1. Measurement system configuration> A detailed description will be given of the measurement system used for inspecting the finished shape of the pit 97. The measurement system includes a measurement unit 10, a control unit 30, and a communication device 35 used at the construction site, an information processing device 40 and a storage device 50 installed in a data center remote from the construction site, a first terminal device 61 carried by a worker at the construction site, and a second terminal device 62 installed at the construction site or in an office nearby.

[0017] (1) Measurement and control units The measurement unit 10 is installed on a platform 91 installed above the opening of the vertical hole 97. The platform 91 is installed on a casing 92 installed along the opening of the vertical hole 97. The control unit 30 is located on the ground at the construction site.

[0018] The measurement unit 10 has a winch 11 , a wire 12 , a winch 13 , a signal cable 14 , a case 15 , two range finders 16 , 17 , and a depth finder 19 .

[0019] The wire 12 is wound around the winch 11. The wire 12 is unwound from the winch 11 and suspended into the vertical hole 97. A case 15 is attached to the end of the wire 12. Two distance meters 16, 17 are housed in the case 15 and fixed to the case 15. The distance meters 16, 17 are connected to a signal cable 14. The signal cable 14 is wired from the distance meters 16, 17 through the winch 13 to the control unit 30. A mid-way portion of the signal cable 14 is wound around the winch 13.

[0020] The winch 11 has a motor. The winch 11 uses the power of the motor to let out the wire 12 and to wind up the wire 12. The winch 11 aligns the case 15 and the distance meters 16, 17 along the central axis of the vertical hole 97, and raises the case 15 and the distance meters 16, 17 by winding up the wire 12. The winch 11 aligns the case 15 and the distance meters 16, 17 along the central axis of the vertical hole 97, and lowers the case 15 and the distance meters 16, 17 by letting out the wire 12. The winch 13 lets out the signal cable 14 when the winch 11 lets out the wire 12. The winch 13 winds up the signal cable 14 when the winch 11 winds up the wire 12. The central axis of the vertical hole 97 is almost vertical, but may be inclined from the vertical line. Furthermore, if the wire 12 does not swing, the ascending and descending trajectories of the range finders 16 and 17 are vertical.

[0021] The two range finders 16, 17 are connected to the control unit 30 via a signal cable 14. The two range finders 16, 17 are attached to the case 15 so as to face opposite each other. When the range finders 16, 17 are suspended in the vertical hole 97, the range finders 16, 17 are horizontally directed toward the casing 92 or the inner wall of the vertical hole 97. The range finders 16, 17 transmit ultrasonic waves in the direction in which the range finders 16, 17 are directed. That is, the range finders 16, 17 transmit ultrasonic waves in the radial direction of the vertical hole 97 toward the inner wall of the casing 92 or the vertical hole 97. The range finders 16, 17 receive reflected waves generated by the transmitted ultrasonic waves being incident on the inner wall of the casing 92 or the vertical hole 97. The distance meter 16, 17 periodically measures the distance to the inner wall of the casing 92 or the vertical hole 97, i.e., the inner diameter, by periodically transmitting ultrasonic waves and receiving reflected waves. For example, the distance meter 16, 17 may measure the distance from the time from transmitting the ultrasonic waves to receiving the reflected waves. For example, the distance meter 16, 17 may measure the distance from the phase difference between the ultrasonic waves and the reflected waves. Each time the distance is measured, the distance meter 16, 17 outputs a signal based on the measured distance to the control unit 30. The sampling period of the distance meter 16, 17 is, for example, 168 ms. In addition to the range finders 16 and 17, two more range finders may be attached to the case 15. The two additional range finders are attached to the case 15 so as to face opposite each other. The directions in which the two additional range finders transmit ultrasonic waves are horizontal directions perpendicular to the directions in which the range finders 16 and 17 transmit ultrasonic waves.

[0022] The depth gauge 19 is connected to the control unit 30 via a wire. The depth gauge 19 periodically measures the depth at which the suspended range finders 16, 17 are located. That is, the depth gauge 19 periodically measures the distance from a reference position (specifically, the platform 91) to the range finders 16, 17 along the central axis of the vertical hole 97. For example, the depth gauge 19 may be a rotary encoder provided on the winch 11. The rotary encoder measures the depth of the range finders 16, 17 from a pulse signal generated by the rotation of the winch 11. The depth gauge 19 may be a range finder installed on the platform 91 directly above the range finders 16, 17. The range finder measures the depth of the range finders 16, 17 by transmitting light waves or ultrasonic waves toward the range finders 16, 17 and receiving reflected waves from the range finders 16, 17. Each time the depth meter 19 measures the depth, it outputs a signal based on the measured depth to the control unit 30.

[0023] The control unit 30 has a power supply circuit, a drive circuit, a signal processing circuit, an interface circuit, etc. The control unit 30 drives the motor of the winch 11 to control the winding speed and the payout speed of the winch 11. The control unit 30 may control the winch 11 at a constant speed. The control unit 30 controls the winch 11 to raise and lower the range finders 16, 17 and the case 15 in the vertical hole 97.

[0024] While the range finders 16, 17 and the case 15 are descending or ascending, the control unit 30 drives the range finders 16, 17 to cause them to perform measurement operations, inputs signals from the range finders 16, 17, and processes the signals to generate discrete data of the measured distances. The discrete data of the measured distances is data in which the measured distances measured by the range finders 16, 17 are arranged in time series. Similarly, when two more range finders are attached to the case 15 in addition to the range finders 16, 17, the control unit 30 generates discrete data of the measured distances measured by those two range finders.

[0025] While the range finders 16, 17 and the case 15 are descending or ascending, the control unit 30 drives the depth meter 19 to synchronize with the range finders 16, 17, causes the depth meter 19 to perform a measurement operation, inputs a signal from the depth meter 19, and processes the signal to generate discrete data of the measured depth. The discrete data of the measured depth is data in which the measured depths measured by the depth meter 19 are arranged in time series. The control unit 30 synchronously transfers the measured distances and measured depths measured at the same timing by the range finders 16, 17 and the depth meter 19 to the communication device 35.

[0026] (2) Communication devices The communicator 35 has a radio and an antenna. The communicator 35 modulates radio waves based on the measured distance and measured depth input from the control unit 30, and transmits the measured distance and measured depth to the information processing device 40 by emitting the radio waves carrying the measured distance and measured depth as data from an antenna. The wireless communication standard of the communicator 35 is, for example, LPWA (Low Power Wide Area-network), WiFi (registered trademark), 3G mobile communication system, LTE, 4G mobile communication system, 5G mobile communication system, ZigBee (registered trademark), Bluetooth (registered trademark), or Z-Wave (registered trademark). The measured distance and measured depth transmitted by the communicator 35 are sent to the information processing device 40 via a network device such as a repeater. The communication path from the communicator 35 to the information processing device 40 may include the Internet, a local area network (LAN), or both.

[0027] (3) Information processing devices and storage devices The information processing device 40 is installed in a data center remote from the construction site of the pit 97. The information processing device 40 is a server configured by a computer system. The information processing device 40 may be configured from one computer system, or may be configured from multiple computer systems capable of distributed processing or parallel processing. The information processing device 40 may be a cloud computing system. The information processing device 40 is connected to the Internet. An OS (Operating System) is installed in the information processing device 40. A program 49 executable on the OS is installed in the information processing device 40.

The storage device 50 may be connected to the information processing device 40 via the Internet or a local area network, and the information processing device 40 may be able to access the storage device 50 via the Internet or the local area network.

[0029] The storage device 50 stores design data 51 of the pile to be constructed in the pit 97. The design data 51 includes pile code, shaft diameter data, bottom expansion diameter data, rise height data, pile length data, bottom expansion angle data, pile head level data, and pile tip level data. The pile code is a code representing the specifications of the pile. The shaft diameter data represents the shaft diameter, that is, the diameter of the pile at the fixed diameter portion 97a. The bottom expansion diameter data represents the diameter of the pile at the rise portion 97c. The rise height data represents the height of the rise portion 97c, that is, the distance from the lower end to the upper end of the rise portion 97c. The pile length data represents the pile length, that is, the length from the lower end of the pile to the upper end of the pile. The bottom expansion angle data represents the bottom expansion angle, that is, the inclination angle of the outer peripheral surface of the pile at the expansion portion 97b. The pile head level data represents the pile head level, that is, the depth of the upper end of the pile. The pile tip level data represents the pile tip level, that is, the depth of the lower end of the pile.

[0030] The storage device 50 stores allowable data 52 for piles constructed in the pit 97. The allowable data 52 consists of shaft diameter allowable data, enlarged bottom diameter allowable data, rise height allowable data, pile length allowable data, pile head level allowable data, and pile tip level allowable data. The shaft diameter allowable data represents the allowable range of pile diameter. The enlarged bottom diameter allowable data represents the allowable range of enlarged bottom diameter. The rise height allowable data represents the allowable range of rise height. The pile length allowable data represents the allowable range of pile length. The pile head level allowable data represents the allowable range of pile head level. The pile tip level allowable data represents the allowable range of pile tip level.

The first terminal device 61 has a CPU, a GPU, a memory, a storage device, an input device, a display device, and a communication module.

[0032] The second terminal device 62 is a computer system such as a laptop computer or a desktop computer. The second terminal device 62 includes a CPU, a GPU, a memory, a storage device, an input device, a display device, a communication module, etc. A printing device 69 is connected to the second terminal device 62.

[0033] An OS (Operating System) is installed in the terminal devices 61 and 62, and application programs executable on the OS are also installed. The OS may be a general-purpose OS such as Windows (registered trademark), Android (registered trademark), iOS (registered trademark), macOS (registered trademark), Linux (registered trademark), or Unix (registered trademark). The terminal devices 61 and 62 access the information processing device 40 based on the application program, receive information provided from the information processing device 40, and display the contents of the provided information on a display device.

[0034] <2. Operation and use of the measurement system> After the pit 97 is excavated, the measurement unit 10, the control unit 30 and the communication device 35 are set up as shown in FIG. Next, the wire 12 and the signal cable 14 are pulled out from the winches 11 and 13, and the wire 12 and the signal cable 14 are hung from the stand 91, and the case 15 and the distance meters 16 and 17 are suspended by the wire 12.

[0035] When the control unit 30 is started, the control unit 30 controls the winch 11, the wire 12 is sent out from the winch 11, and the case 15 and the range finders 16 and 17 are lowered. Note that the control unit 30 may be started after the case 15 and the range finders 16 and 17 are lowered to the bottom of the shaft 97. In this case, the control unit 30 controls the winch 11, the wire 12 is wound on the winch 11, and the case 15 and the range finders 16 and 17 are raised.

[0036] While the case 15 and the range finders 16, 17 are descending or ascending, the control unit 30 causes the range finders 16, 17 and the depth meter 19 to perform periodic measurement operations. The control unit 30 synchronously transfers the measured distances and measured depths measured at the same timing by the range finders 16, 17 and the depth meter 19 to the communication device 35, and the communication device 35 transmits the measured distances and measured depths input from the control unit 30 to the information processing device 40. Meanwhile, the information processing device 40 is running a program 49, which causes the information processing device 40 to execute the following processes.

[0037] (1) Record processing Every time the information processing device 40 receives the measured distance and the measured depth from the communication device 35, the information processing device 40 associates the measured distance and the measured depth with each other and records the measured distance and the measured depth in chronological order in the storage device 50. In this way, the information processing device 40 accumulates in the storage device 50 discrete measurement data 53 in which the associated measured distances and measured depths are arranged in chronological order. A combination of the associated measured distances and measured depths is hereinafter referred to as a data set. The measured distances and measured depths included in the data set are measured at the same timing.

[0038] (2) Identifying hole size and judging pass / fail The information processing device 40 calculates the sum of the measured distances for each data set. Next, the information processing device 40 identifies the smallest sum by comparing the sums for each data set, and identifies it as the hole diameter. The hole diameter can also be said to be the shaft diameter, that is, the diameter of the pile. The information processing device 40 may identify the average, median, or maximum value of the sums for each data set as the hole diameter.

[0039] Next, the information processing device 40 compares the identified hole diameter with the shaft diameter tolerance data of the tolerance data 52 to determine whether the identified hole diameter falls within the range of the shaft diameter tolerance data.

[0040] Next, the information processing device 40 records the identified hole diameter and the judgment result in the storage device 50 in association with the measurement data 53. Note that the information processing device 40 may update the hole diameter recorded in the storage device 50 to an input value according to the operation of the first terminal device 61 or the second terminal device 62 by an operator operating the first terminal device 61 or the second terminal device 62. Also, without the information processing device 40 identifying the hole diameter, the information processing device 40 may record the input value according to the operation of the first terminal device 61 or the second terminal device 62 in the storage device 50 as the hole diameter and the judgment result.

[0041] (3) Identifying the depth of the pit and judging whether it passes or fails The information processing device 40 compares the measurement depths of the respective data sets and identifies the maximum measurement depth as the depth of the bottom of the pit 97. Here, the depth of the bottom of the pit 97 is based on the stand 91. The depth of the bottom of the pit 97 corresponds to the pile tip level.

[0042] Next, the information processing device 40 compares the identified pile tip level (depth of the bottom of the vertical hole 97) with the pile tip level tolerance data of the tolerance data 52, and determines whether the identified pile tip level falls within the range of the pile tip level tolerance data.

[0043] Next, the information processing device 40 records the specified pile tip level and the judgment result in the storage device 50 in association with the measurement data 53. Note that the worker may operate the first terminal device 61 or the second terminal device 62, causing the information processing device 40 to update the pile tip level and its judgment result recorded in the storage device 50 to an input value according to the operation of the first terminal device 61 or the second terminal device 62. Also, without the information processing device 40 specifying the pile tip level, the worker may operate the first terminal device 61 or the second terminal device 62, causing the information processing device 40 to record the input value according to the operation of the first terminal device 61 or the second terminal device 62 as the pile tip level and its judgment result in the storage device 50.

[0044] (4) Identification of the enlarged diameter and pass / fail judgment For example, the information processing device 40 calculates the sum of the measurement distances of the data set having the maximum measurement depth, and specifies the sum as the expanded-bottom diameter. The information processing device 40 may calculate the expanded-bottom diameter by other algorithms using the measurement data 53. The information processing device 40 may not execute the calculation process of the expanded-bottom diameter.

[0045] Next, the information processing device 40 compares the identified expanded-bottom diameter with the expanded-bottom diameter allowable data of the allowable data 52 to determine whether the identified expanded-bottom diameter falls within the range of the expanded-bottom diameter allowable data. Note that the information processing device 40 does not have to perform such a determination process.

[0046] Next, the information processing device 40 records the identified expanded diameter and the judgment result in the storage device 50 in association with the measurement data 53. Note that the information processing device 40 may update the expanded diameter and its judgment result recorded in the storage device 50 to input values ​​according to the operation of the first terminal device 61 or the second terminal device 62 by an operator operating the first terminal device 61 or the second terminal device 62. Also, without the information processing device 40 identifying the expanded diameter, the information processing device 40 may record input values ​​according to the operation of the first terminal device 61 or the second terminal device 62 as the expanded diameter and its judgment value in the storage device 50 by an operator operating the first terminal device 61 or the second terminal device 62. In addition, when the vertical hole 97 is used for a straight pile, the content of this section (5) is omitted.

[0047] (5) Identifying the rise height and judging pass / fail The information processing device 40 calculates the sum of the measured distances for each data set. The information processing device 40 reads the sums of the measured distances in descending order of the measured depth, and identifies the measured depth at which the change in the sum of the measured distances becomes rapidly large. The measured depth identified in this way corresponds to the depth of the upper end of the rising portion 97c. The information processing device 40 subtracts the measured depth identified in this way from the depth of the bottom of the pit 97, and identifies the difference as the rising height. Note that the information processing device 40 may calculate the rising height by another algorithm using the measurement data 53. The information processing device 40 may not execute the calculation process of the rising height.

[0048] Next, the information processing device 40 compares the identified rising height with the rising height tolerance data of the tolerance data 52 to determine whether the identified rising height falls within the range of the rising height tolerance data. Note that the information processing device 40 does not have to execute such a determination process.

[0049] Next, the information processing device 40 records the identified rise height and the determination result in the storage device 50 in association with the measurement data 53. Note that the information processing device 40 may update the rise height recorded in the storage device 50 to an input value according to the operation of the first terminal device 61 or the second terminal device 62 by the worker operating the first terminal device 61 or the second terminal device 62. Also, without the information processing device 40 identifying the rise height, the information processing device 40 may record the input value according to the operation of the first terminal device 61 or the second terminal device 62 as the rise height and its determination result in the storage device 50 by the worker operating the first terminal device 61 or the second terminal device 62. In addition, when the vertical hole 97 is used for a straight pile, the content of this section (6) is omitted.

[0050] (6) Calculation of pile length and pass / fail judgment The information processing device 40 subtracts the pile head level from the depth of the bottom of the pit 97, and specifies the difference as the pile length. The depth of the bottom of the pit 97 is specified as in (4) above. The pile head level is an actual measurement value input to the information processing device 40 after the pile is constructed in the pit 97. Specifically, when a worker actually measures the pile head level after constructing the pile and inputs the actual measurement value to the first terminal device 61, the first terminal device 61 transfers the actual measurement value to the information processing device 40, and the information processing device 40 acquires the actual measurement value and records it in the storage device 50 in association with the measurement data 53. Note that if the actual measurement value of the pile head level has not been input, the information processing device 40 does not calculate the pile length, and specifies the pile length as "uncalculated".

[0051] Next, the information processing device 40 compares the identified pile length with pile length tolerance data of the tolerance data 52, and determines whether the identified pile length falls within the range of the pile length tolerance data.

[0052] Next, the information processing device 40 compares the input actual measurement value of the pile head level with the pile head level tolerance data of the tolerance data 52 and determines whether the input actual measurement value of the pile head level falls within the range of the pile head level tolerance data of the tolerance data 52.

[0053] Next, the information processing device 40 records the specified pile length and the judgment result in the storage device 50 in association with the measurement data 53. Note that the worker may operate the first terminal device 61 or the second terminal device 62, causing the information processing device 40 to update the pile length and the judgment result recorded in the storage device 50 to an input value according to the operation of the first terminal device 61 or the second terminal device 62. Also, without the information processing device 40 specifying the pile length, the worker may operate the first terminal device 61 or the second terminal device 62, causing the information processing device 40 to record the input value according to the operation of the first terminal device 61 or the second terminal device 62 as the pile length and the judgment result in the storage device 50.

[0054] (7) Display of completed form A worker at the construction site starts an application program of the first terminal device 61. Then, the first terminal device 61 accesses the information processing device 40 and gives a command to the information processing device 40. The information processing device 40, which receives the command, generates a graph 100 as shown in FIG. 2 by plotting each data set with the measured distance on the horizontal axis and the measured depth on the vertical axis with reference to the measurement data 53. At this time, the information processing device 40 plots each data set with the measured distance measured by one of the range finders 16 and 17 as positive and the measured distance measured by the other as negative. A line 101 in the graph 100 is a plot of the measured distance measured by the range finder 16. A line 102 in the graph 100 is a plot of the measured distance measured by the range finder 17. The information processing device 40 generates a pile image 103 based on the pile design data 51, and synthesizes the pile image 103 on the graph 100 as shown in FIG. 2. The information processing device 40 places the numerical values ​​of the pile design data 51 in a display area 104 near the graph 100. The information processing device 40 generates data for displaying the graph 100 in which the numerical values ​​of the pile design data 51 and the pile image 103 are combined, and transmits the data to the first terminal device 61. When the first terminal device 61 receives the data, it displays the graph 100 in which the numerical values ​​of the pile design data 51 and the pile image 103 are combined based on the data.

[0055] The information processing device 40 may synthesize the specified hole diameter and the judgment result of the pass / fail thereof on the graph 100 and the pile image 103, so that the specified hole diameter and the judgment may be displayed by the first terminal device 61. The information processing device 40 may synthesize the specified pile tip level (depth of the bottom of the pit 97) and the judgment result of the pass / fail thereof on the graph 100 and the pile image 103, so that the specified pile tip level and the judgment result may be displayed on the first terminal device 61. The information processing device 40 may synthesize the specified bottom expansion diameter and the judgment result of the pass / fail thereof on the graph 100 and the pile image 103, so that the specified bottom expansion diameter and the judgment result may be displayed on the first terminal device 61. The information processing device 40 may synthesize the specified rise height and the judgment result of the pass / fail thereof on the graph 100 and the pile image 103, so that the specified rise height and the judgment result may be displayed on the first terminal device 61. The information processing device 40 may synthesize the input actual measurement value of the pile head level and the pass / fail judgment result on the graph 100 and the pile image 103, so that the input actual measurement value of the pile head level and the judgment result may be displayed on the first terminal device 61. The information processing device 40 may synthesize the calculated pile length and the pass / fail judgment result on the graph 100 and the pile image 103, so that the calculated pile length and the judgment result may be displayed on the first terminal device 61.

[0056] (8) Printing reports An office worker starts an application program on the second terminal device 62. Then, the second terminal device 62 accesses the information processing device 40 and issues a command to the information processing device 40. The information processing device 40, which receives the command, generates and synthesizes a graph 200 and a pile image 203 as shown in FIG. 3, similar to the process in "(9) Display of completed form" above. A line 201 in the graph 200 is a plot of the measured distance measured by the range finder 16. A line 202 in the graph 200 is a plot of the measured distance measured by the range finder 17.

[0057] The information processing device 40 reads the pile design data 51 and the allowable data 52 from the storage device 50. Furthermore, the information processing device 40 reads the hole diameter (shaft diameter), the depth of the vertical hole 97 (pile tip level), the enlarged bottom diameter, the rise height, the pile length, and the pile head level, as well as the pass / fail judgment results thereof, from the storage device 50. The information processing device 40 generates a table 204 as shown in FIG. 3 based on the read data, and synthesizes the table 204 near the graph 200 and the pile image 203. In the table 204, the first column 204a indicates the item name. The second column 204b indicates the value of each item in the design data 51. The third column 204c indicates the values ​​of the hole diameter (shaft diameter), the depth of the vertical hole 97 (pile tip level), the enlarged bottom diameter, the rise height, the pile length, and the pile head level specified or calculated by the information processing device 40 from the measurement data 53 or 54. The fourth column 204d indicates the value of each item in the allowable data 52. The fifth column 204e indicates the pass / fail judgment result for each item. If the judgment result is displayed as "○", it means that the hole diameter (shaft diameter), the depth of the pit 97 (pile tip level), the enlarged bottom diameter, the rise height, the pile length, or the pile head level falls within the range in the allowable data 52. If the judgment result is displayed as "×", it means that the hole diameter (shaft diameter), the depth of the pit 97 (pile tip level), the enlarged bottom diameter, the rise height, the pile length, or the pile head level does not fall within the range in the allowable data 52. At least one of all the columns (cells) in the columns 204a to 204d may be blank. In addition, the worker may operate the second terminal device 62 to update the data or numerical value in at least one of all the columns in the columns 204a to 204d. In addition, when a worker operates the first terminal device 61 or the second terminal device 62, the information processing device 40 records the input value according to the operation of the first terminal device 61 or the second terminal device 62 in the storage device 50 as the casing top level, and the input value may be reflected in table 204.

[0058] The information processing device 40 generates data for displaying the graph 200 in which the stake image 203 and the table 204 are combined, and transmits the data to the second terminal device 62. When the second terminal device 62 receives the data, it displays the graph 200 in which the stake image 203 and the table 204 are combined based on the data. Furthermore, the worker issues a print command to the second terminal device 62 by operating the second terminal device 62. The second terminal device 62, which has received the command, generates a job for printing the graph 200 in which the stake image 203 and the table 204 are combined, and outputs the job to the printer 69. The printer 69 then prints the graph 200 in which the stake image 203 and the table 204 are combined.

[0059] <3. Summary> When a worker measures the pit 97 at the construction site using the measurement unit 10, the control unit 30, and the communication device 35, the measurement data 53 as the completed form information of the pit 97 is recorded in the storage device 50. Therefore, the completed form information can be conveniently managed and handled. For example, the contents of the measurement data 53 can be viewed and shared by the terminal devices 61, 62 having the access authority to the information processing device 40.

[0060] Since the graph 100 showing the completed shape of the pit 97 and the pile image 103 are displayed on the first terminal device 61, a worker at the construction site can easily check whether the completed shape of the pit 97 is good or bad by comparing the graph 100 with the pile image 103. Similarly, a worker in the office can easily and quickly check whether the completed shape of the pit 97 is good or bad by comparing the graph 200 with the pile image 203.

[0061] The information processing device 40 specifies and calculates the hole diameter (shaft diameter), the depth of the pit 97 (pile tip level), the enlarged bottom diameter, the rise height, and the pile length based on the measurement data 53, and these are displayed on the terminal devices 61, 62. Therefore, workers at the construction site or in the office can easily check the completed shape of the pit 97 in a short time.

[0062] The information processing device 40 compares the specified hole diameter (shaft diameter), depth of the pit 97 (pile tip level), enlarged bottom diameter, rise height, pile length, and the like with the allowable data 52, and the judgment result of the comparison is displayed on the terminal devices 61, 62. Therefore, workers at the construction site or in the office can easily and quickly check whether the completed shape of the pit 97 is good or bad. In particular, the displayed or printed table 204 contributes to the worker being able to understand at a glance whether each item of the completed shape of the pit 97 is good or bad.

[0063] The graph 200, which is a composite of the stake image 203 and the table 204, is printed by the printer 69, so that the printout can be used as a form. The printout can also be stored. Various information can also be written on the printout.

[0064] <4. Modifications> The information processing device 40 may execute the following process.

[0065] The information processing device 40 identifies a data set having a measurement depth equal to the pile head level from among a plurality of data sets of the measurement data 53. Here, the pile head level is an actual measurement value inputted into the information processing device 40 after the pile is constructed in the pit 97, as described above. Next, the information processing device 40 calculates the half value of the difference in the measurement distance of the data set having the measurement depth equal to the pile head level, as shown in the following formula (1). top1 is the distance measured by one of the distance meters 16, and R top2 is the distance measured by the other distance meter 17, and E top is half the difference in the measured distances. E top can also be said to be the amount of eccentricity from the central axis of the vertical hole 97 at the pile head level to the distance meters 16 and 17.

[0067] The information processing device 40 identifies, from among a plurality of data sets of the measurement data 53, a data set having the maximum measurement depth (pile tip level). Next, the information processing device 40 calculates the half value of the difference in the measurement distance of the data set having the maximum measurement depth as shown in the following formula (2). bottom1 is the distance measured by one of the distance meters 16, and R bottom2 is the distance measured by the other distance meter 17, and E bottom is half the difference in the measured distances. E bottom can also be said to be the amount of eccentricity from the central axis of the vertical hole 97 at the pile tip level to the distance meters 16 and 17.

[0068]

number

[0069] Next, the information processing device 40 calculates the inclination angle of the central axis of the vertical hole 97 with respect to the vertical line based on the pile length and the eccentricity at the pile head level and the pile tip level as shown in the following formula (3). Here, in formula (3), θ is the inclination angle, and L is the pile length.

[0070]

number

[0071] Next, the information processing device 40 compares the calculated inclination angle with the inclination angle tolerance data to determine whether the calculated inclination angle falls within the range of the inclination angle tolerance data. Here, the inclination angle tolerance data is included in the tolerance data 52, and the inclination angle tolerance data represents the tolerance range of the inclination angle. The design data 51 also includes a design value of the inclination angle.

[0072] Next, the information processing device 40 records the calculated inclination angle and the determination result in the storage device 50 in association with the measurement data 53. Note that the information processing device 40 may update the inclination angle and the determination result recorded in the storage device 50 to input values ​​according to the operation of the first terminal device 61 or the second terminal device 62 by the worker operating the first terminal device 61 or the second terminal device 62. Also, without the information processing device 40 calculating the inclination angle, the information processing device 40 may record the input values ​​according to the operation of the first terminal device 61 or the second terminal device 62 as the inclination angle and its determination result in the storage device 50 by the worker operating the first terminal device 61 or the second terminal device 62.
