Description

Technical Field

[0001] The present disclosure relates to a construction management system, a construction management method, and a construction management program for assisting in confirming the reach of a support layer of a pile hole for installing a pile.

Background Art

[0002] When constructing a structure, in some cases, a plurality of piles are driven into a support layer, and the load of the structure is supported in the support layer via the piles. Therefore, the pile holes for arranging the piles are made to reach the support layer. However, it is difficult to define qualitative judgment criteria in confirming the reach to the support layer. Thus, techniques for determining the reach of the drilled hole to the support layer have been studied (see, for example, Patent Document 1). The judgment support system described in Patent Document 1 includes a pile management information storage unit that stores the support layer depth at the site, and a control unit connected to a judgment terminal and a confirmation terminal. When the control unit acquires the determined support layer depth at the site, it records it in the pile management information storage unit in association with the site identifier at the site. Next, when the control unit acquires, from the judgment terminal, a new support layer depth determined by the judge to have reached the support layer according to a plurality of drilling status information in the drilling of the pile hole to be processed, the control unit acquires the determined support layer depth at the same site as the pile hole to be processed from the pile management information storage unit. Then, the control unit outputs confirmation information including the acquired determined support layer depth and the new support layer depth to the confirmation terminal.

Modes for Carrying Out the Invention

[0008] Hereinafter, an embodiment in which the construction management system, construction management method, and construction management program of the present embodiment are embodied will be described with reference to FIGS. 1 to 6. Here, the confirmation work of the person who confirms the reaching depth of the support layer is supported. As shown in FIG. 1, when excavating a pile hole h0 for installing a pile of a building, an excavator 10 as an excavating device is used. The excavator 10 includes a base machine 11, a mast 14, and an auger machine 16. The base machine 11 includes a lower traveling body including crawlers 12 and an upper revolving body including an operation cab 13.

[0009] The mast 14 is erected on the base machine 11. A wire for measuring depth and speed is provided inside the mast 14. An auger machine 16 is attached to the mast 14 via a support portion 15 so as to be movable up and down. The auger machine 16 includes a drive motor housed in a box and a drilling rod 17 rotationally driven by this drive motor. A drilling head 18 is attached to the tip (lower end) of the drilling rod 17. The drilling head 18 has cutting edges formed at the tips of a pair (two) of swinging drilling arms. Note that the raising and lowering of the drilling head 18 is controlled by an operator in the operation cab 13.

[0010] In addition, a drilling water supply device (not shown) for supplying drilling water to the drilling head 18 is connected to the excavator 10. The amount of this drilling water is adjusted by the operator in the operation cab 13 according to the drilling situation. In drilling management, a measurement unit 20, a management device 40, a determiner device 51, and a checker device 52 connected by a network are used. Details of these will be described later.

[0011] (Hardware configuration example) FIG. 2 is a hardware configuration example of an information processing device H10 that functions as a measurement unit 20, a management device 40, a determiner device 51, a checker device 52, and the like.

[0012] The information processing device H10 includes a communication device H11, an input device H12, a display device H13, a storage device H14, and a processor H15. Note that this hardware configuration is an example, and it may have other hardware.

[0013] The communication device H11 is an interface that establishes a communication path with other devices and performs data transmission and reception. The input device H12 is a device that receives user input.

[0014] The display device H13 is a display, a touch panel, or the like that displays various information. The storage device H14 stores data and various programs for executing the various functions of the measurement unit 20, the management device 40, the determiner device 51, and the checker device 52. Examples of the storage device H14 include a ROM, a RAM, a hard disk, and the like. The processor H15 controls each process in the measurement unit 20, the management device 40, the determiner device 51, and the checker device 52 using the programs and data stored in the storage device H14.

[0015] (Explanation of the functions of the construction management system) As shown in FIG. 1, the measurement unit 20 of the excavator 10 includes a depth gauge 21, an ammeter 22, a flow meter 23, and a vibration meter 24. The measured values of the depth gauge 21 to the vibration meter 24 are affected by the hardness of the excavated ground.

[0016] The depth gauge 21 measures the amount of wire paid out in the mast 14 and measures the drilling depth (depth) corresponding to the position of the drill head 18. If the drilling speed is slow according to the drilling depth measured by the depth gauge 21, it indicates that the excavated ground is hard. The ammeter 22 measures the load current of the drive motor of the auger machine 16. If the load current is large, it indicates that the excavated ground is hard.

[0017] The flow meter 23 measures the injection flow rate of the drilling water supplied from the drilling water supply device. If the injection flow rate is large, it indicates that the excavated ground is hard. The vibration meter 24 measures the vibration at the mounting location. In this embodiment, the vibration meter 24 is mounted inside the operation room 13, on the roof of the operation room 13, or on the operation lever inside the operation room 13. This vibration meter 24 measures the vibration in the vertical direction and the horizontal direction. Note that the installation location of the vibration meter 24 is not limited to the operation room 13, and any location where the vibration during excavation is transmitted is acceptable. For example, it may be mounted on the mast 14 or the like.

[0018] As shown in FIG. 3, the management device 40 acquires various information from the measurement unit 20. The management device 40 is a computer system used by the manager at the construction site. The management device 40 includes a control unit 41, a geological survey information storage unit 42, a construction information storage unit 43, and a pile information storage unit 44.

[0019] The control unit 41 performs various processes (each process such as the acquisition stage and the determination stage). For this purpose, by executing the drilling management program stored in the memory, the control unit 41 functions as an acquisition unit 411 and a determination unit 412.

[0020] The acquisition unit 411 acquires various information from the depth meter 21 to the vibration meter 24 of the measurement unit 20, and executes a process of registering the acquired information in the construction information storage unit 43. The determination unit 412 executes a process of determining the arrival at the bearing layer using the construction data. Further, the determination unit 412 specifies the depth when the arrival at the bearing layer is determined.

[0021] The geological survey information storage unit 42 records the geological survey information obtained by the boring survey. This geological survey result information is recorded before the excavation of the pile hole h0. The geological survey result information includes data related to the N value according to the site identifier, the survey position (coordinates), and the depth.

[0022] In the site identifier data area, data related to the site identifier for specifying the site where the boring survey was conducted is recorded. In the survey position data area, data related to the position (coordinates) where the boring survey was conducted at this site is recorded.

[0023] In the N - value data area according to the depth, data regarding the N - values created based on the standard penetration test data obtained in this boring survey is recorded. This N - value is recorded in association with the depth.

[0024] In the construction information storage unit 43, construction management information including the construction data acquired from the measurement unit 20 is recorded. This construction management information is recorded when acquired from the measurement unit 20. This construction management information records an excavator folder, a pile folder, and construction data.

[0025] The excavator folder is provided in the constructor folder and is a storage folder set for each identification information (machine number) of the excavator. The pile folder is provided in the excavator folder and is a storage folder set for each pile number. When the excavation of the pile hole h0 is performed, the construction data acquired from the measurement unit 20 is stored in the pile folder.

[0026] The construction data includes measurement history data regarding the management items and management item values for each construction time. The construction time is the year, month, day, and time, and is recorded regularly (for example, every 1 second or every 2 seconds). In this embodiment, as the management items, depth, current value, water volume, and vibration amount are used.

[0027] In the pile information storage unit 44, pile management information regarding the piles used for the building constructed on - site is stored. This pile management information is registered when the building is designed on - site and the positions of the piles are determined, and is recorded and updated when the construction status information of the pile hole h0, the depth of the bearing layer, etc. are acquired. The pile management information includes data regarding the site identifier, pile identifier, position of the pile, attribute information of the pile, construction machine identifier, determiner information, bearing layer reaching depth, items for determination basis, checker information, and status.

[0028] In the site identifier data area and the pile identifier data area, a site identifier for specifying the site where the pile is installed and a pile identifier for specifying the pile are recorded respectively. In the pile position data area and the pile attribute information, data regarding the position (coordinates) of the pile at the construction site, and attribute information such as the shape, pile diameter, and pile length of the pile are respectively recorded.

[0029] In the construction machine identifier data area, an identifier for specifying the construction machine (excavator 10) used to form the pile hole h0 for installing this pile is recorded. In the determiner information data area, data regarding the determiner who determined that the pile hole h0 reached the bearing layer is recorded. In this embodiment, this determiner information includes a user identifier for specifying the determiner and the email address of the determiner device 51.

[0030] In the bearing layer reach depth data area and the determination basis item data area, the depth (bearing layer depth) when the excavated pile hole h0 is determined to have reached the bearing layer, and data regarding the item that serves as the basis when it is determined that the bearing layer has been reached are respectively recorded.

[0031] In the verifier information data area, data regarding the verifier who verifies the depth (new bearing layer depth) determined by the determiner to have reached the bearing layer is recorded. In this embodiment, this verifier information includes a user identifier for specifying the verifier and the email address of the verifier device 52. In the status data area, the status (situation) regarding the determination of reaching the bearing layer is recorded. For example, statuses such as during excavation, waiting for confirmation, rework, and confirmed are recorded.

[0032] The determiner device 51 is a computer terminal (user terminal) used by the determiner (user) of reaching the bearing layer at the construction site. Using the determiner device 51, the determiner performs the determination operation regarding the depth of the pile reaching the bearing layer.

[0033] The verifier device 52 is a computer terminal (user terminal) used by the verifier (user). Using the verifier device 52, the verifier performs the verification operation regarding the depth of the pile reaching the bearing layer determined by the determiner.

[0034] (Construction management process) Using FIG. 4, the construction management process will be described. This management process is performed during the excavation of the pile hole h0 to determine whether the pile hole h0 of the newly installed pile has reached the support layer.

[0035] First, the control unit 41 of the management device 40 executes a process of acquiring excavation start information (step S11). Specifically, the determiner device 51 accesses the management device 40 and transmits an excavation start notification to the management device 40 according to the operation of the determiner. The acquisition unit 411 of the control unit 41 acquires the excavation start notification from the determiner device 51. This excavation start notification includes the site identifier input by the determiner and the position of the pile hole h0 to be excavated. In this case, the acquisition unit 411 records "under excavation" as the status of the pile management information in the pile information storage unit 44.

[0036] Next, the control unit 41 of the management device 40 executes a process of transmitting detailed information (step S12). Specifically, the acquisition unit 411 of the control unit 41 extracts the pile management information including the acquired site identifier and the position of the pile hole (pile) h0 from the pile information storage unit 44. Further, the control unit 41 acquires the N value corresponding to the depth of the geological survey result information at the position closest to the position of this pile hole h0 from the geological survey information storage unit 42. Then, the control unit 41 transmits the pile identifier, the attribute information of the pile, and the N value corresponding to the acquired depth in the pile management information to the determiner device 51.

[0037] Next, the control unit 41 of the management device 40 executes a process of acquiring the excavation status (step S13). Specifically, according to the instruction of the determiner, the rotation of the drive motor of the auger machine 16 of the excavator 10 is started, and the excavation head 18 is inserted into the ground to start excavation. In this case, the measurement unit 20 acquires the measured values measured by each measuring instrument (21 to 24) every predetermined time. Then, the measurement unit 20 transmits the construction data including the measured values to the management device 40. This construction data includes information regarding depth, current value, water volume, vibration amount, etc. In this case, the acquisition unit 411 of the control unit 41 acquires the construction data from the measurement unit 20. And the acquisition unit 411 acquires the construction data together with the identification information (machine number) of the excavator and the identification information (pile number) of the pile at each excavation time.

[0038] Furthermore, the acquisition unit 411 identifies the excavation speed and vibration characteristic values in the excavation time zone using the measurement values from each measuring instrument (21 to 24). In this case, the acquisition unit 411 records the construction data (item values for each management item) in the pile folder (construction information storage unit 43) in the excavator folder corresponding to the identification information (machine number) of the excavator corresponding to the measurement unit 20 from which the information was acquired. Then, the determination unit 412 displays the excavation status information corresponding to the excavation depth in the specified excavation time zone, together with the excavated depth, on the work screen of the determiner device 51. Here, the work screen includes the excavation speed (excavation time), water injection volume, current value, integrated current value, vibration characteristic values, and the like.

[0039] Next, the control unit 41 of the management device 40 executes the acquisition process for the registration request (step S14). Specifically, the determiner determines whether the excavated pile hole h0 has reached the bearing layer while checking the work screen. In this case, the determiner determines based on the N value of the excavation depth and the excavation status information on the work screen. Then, when the determiner determines that the pile hole h0 has reached the bearing layer, the determiner selects the determiner input button on the work screen.

[0040] When the determiner input button is selected, the determiner device 51 displays a bearing layer depth input screen. This bearing layer depth input screen includes an input field for the bearing layer depth, a selection field for selecting the item for the basis when it is determined that the bearing layer has been reached, and an input button. The determiner inputs the determined bearing layer depth (new bearing layer depth), selects the item used as the basis in the selection field, and then presses the input button. In this case, the determiner device 51 sends a registration request for the new bearing layer depth to the management device 40. The registration request includes information regarding the site identifier, pile identifier, new bearing layer depth, and the item for the determination basis. In this case, the determination unit 412 of the control unit 41 acquires the registration request from the determiner device 51. Then, the determination unit 412 records the new bearing layer depth and the item for the determination basis in the pile management information (to be confirmed) corresponding to the site identifier and pile identifier in the pile information storage unit 44. Then, the determination unit 412 records "awaiting confirmation" as the status in the pile information storage unit 44.

[0041] Next, the control unit 41 of the management device 40 executes a peripheral information acquisition process (step S15). Specifically, the determination unit 412 of the control unit 41 extracts pile management information with a status of "confirmed" from the pile information storage unit 44 for piles arranged in a row including the pile to be confirmed. Here, the pile management information of the peripheral piles is extracted with the position of the pile hole to be confirmed as the center. For example, within a predetermined first range, pile management information located in the first direction or the second direction orthogonal to the first direction and having a support layer depth recorded as "confirmed" in the status is extracted. Note that the direction is not limited as long as the support layer depth can be obtained in the order of the piles. Then, the control unit 41 acquires the pile length and the support layer depth of the identified pile management information.

[0042] Next, the control unit 41 of the management device 40 executes a confirmation request process (step S16). Specifically, the determination unit 412 of the control unit 41 identifies the confirmatory information of the pile management information to be confirmed and sends a confirmation request to the email address of this confirmatory information. This confirmation request includes a site identifier and a pile identifier for identifying the pile hole h0 to be confirmed.

[0043] Next, the control unit 41 of the management device 40 executes a comparison display process (step S17). Specifically, when there is an access from the confirmatory device 52, the determination unit 412 of the control unit 41 generates a confirmation screen.

[0044] As shown in FIG. 5, this confirmation screen 500 includes the pile lengths and the support layer depths of a plurality of other piles (P1 to P6) arranged in a row with respect to the object to be confirmed, starting from the position of the pile hole Px to be confirmed. Here, the support layer depths in the first direction on one side and the second direction on the other side are displayed in the order of the piles. Further, on the confirmation screen 500, an input icon 501 that can be tapped for input is displayed at the position of the support layer depth of the object to be confirmed. Then, the determination unit 412 outputs the generated confirmation screen 500 to the display device H13 of the confirmatory device 52.

[0045] Next, the control unit 41 of the management device 40 executes a process for specifying the input position (step S18). Specifically, the verifier uses the verifier device 52 to confirm the support layer depth. Then, a tap operation is performed on the position of the confirmed support layer depth. When the determination unit 412 of the control unit 41 detects a tap operation on the confirmation screen 500, it specifies the tap operation position of the verifier.

[0046] Next, the control unit 41 of the management device 40 executes a determination process as to whether the selection is completed (step S19). Specifically, when the determination unit 412 of the control unit 41 determines that the tap operation position matches within the predetermined range of the input icon 501, it determines that the selection is completed. On the other hand, when it is determined that the tap operation position is outside the predetermined range of the input icon 501 and does not match, it determines that the selection is not completed.

[0047] When it is determined that the selection is completed (in step S19, when "YES"), the control unit 41 of the management device 40 executes a detailed display process (step S20). Specifically, the determination unit 412 of the control unit 41 extracts the pile management information (object to be confirmed) from the pile information storage unit 44. Further, the determination unit 412 acquires the N value corresponding to the depth of the geological survey result information at the position closest to the position of this pile hole from the geological survey information storage unit 42. Then, the determination unit 412 generates a detailed display screen. This detailed display screen includes the pile identifier of the pile management information, the attribute information of the pile, the N value corresponding to the acquired depth, and information related to the construction data.

[0048] As shown in FIG. 6, this detailed display screen 510 includes a constructor column, a pile number column, a support layer confirmation depth column, an excavation time column, a current column, an integrated current column, a vibration column, a water volume column, etc. In this vibration column, a spectrogram whose horizontal axis is the vibration frequency and vertical axis is the frequency distribution of the depth is displayed. Further, the detailed display screen 510 includes a confirmation icon 511 and a return icon 512.

[0049] Next, the determination unit 412 outputs the detailed display screen 510 to the display device H13 of the verifier device 52. The verifier checks the content displayed on the detailed display screen 510. Then, on the detailed display screen 510, the verifier selects either the confirmation icon 511 or the return icon 512. In this case, the verifier device 52 transmits the confirmation result information to the management device 40. This confirmation result information includes information indicating either confirmed or returned.

[0050] Next, the control unit 41 of the management device 40 executes a determination process as to whether it has been confirmed (step S21). Specifically, the determination unit 412 of the control unit 41 determines whether it has been confirmed according to the approval result information acquired from the verifier device 52.

[0051] If the confirmation result information includes information indicating confirmed and it is determined that it has been confirmed (in the case of "YES" in step S21), the control unit 41 of the management device 40 executes a process for determining the support layer reach depth (step S22). Specifically, the determination unit 412 of the control unit 41 records confirmed as the status in the pile information storage unit 44.

[0052] On the other hand, if the confirmation result information includes information indicating return and it is determined that it is not yet confirmed (in the case of "NO" in step S21), the control unit 41 of the management device 40 executes a modification request process (step S23). Specifically, the determination unit 412 of the control unit 41 records return as the status in the pile information storage unit 44. Next, the determination unit 412 transmits a modification instruction to the determiner device 51. In this case, the determiner restarts the auger machine 16 of the excavator 10 and inserts the excavation head 18 into the ground to continue excavation.

[0053] (Operation of the Embodiment) On the confirmation screen used by the verifier at the time of confirmation, an icon capable of inputting confirmation is displayed in an arrangement corresponding to the support layer depth to be confirmed.

[0054] (Effect of the Embodiment) (1) In this embodiment, the control unit 41 of the management device 40 executes the detailed information transmission process (step S12) and the excavation status acquisition process (step S13). Thereby, the determiner can determine the arrival at the support layer.

[0055] (2) In this embodiment, the control unit 41 of the management device 40 executes the surrounding information acquisition process (step S15), the confirmation request process (step S16), and the comparison display process (step S17). Thereby, the depth of the support layer to be confirmed can be determined by comparing with the surrounding situation. Furthermore, since the tap operation position for inputting confirmation changes according to the depth of the support layer to be confirmed, the depth of the support layer can be confirmed by pointing.

[0056] This embodiment can be implemented with the following modifications. This embodiment and the following modification examples can be implemented in combination with each other within a technically non - conflicting range. · In the above - mentioned embodiment, the control unit 41 of the management device 40 executes the excavation status acquisition process (step S13). This construction data includes information regarding depth, current value, water volume, vibration amount, etc., but the construction data is not limited to these. Some of these or other management items may be included.

[0057] · In the above - mentioned embodiment, the control unit 41 of the management device 40 executes the comparison display process (step S17). Here, on the confirmation screen, at the position of the support layer depth to be confirmed, it is made tappable so that confirmation can be input. If the input position can be changed according to the position of the support layer depth, it is not limited to the position of the support layer depth to be confirmed. For example, while tapping the support layer depths of the surrounding piles to be confirmed in order, the position of the support layer depth to be confirmed may be tapped. In this case, the control unit 41 of the management device 40 specifies the tap operation positions in order in the input position specifying process (step S18) and collates them with the support layer depths of the surrounding piles.

[0058] ·In the above embodiment, the control unit 41 of the management device 40 executes the specific processing of the input position (step S18). The confirmation input method is not limited to tapping. For example, a flick operation may be used.

[0059] ·In the above embodiment, the control unit 41 of the management device 40 executes the comparison display processing (step S17). Here, the output form of the confirmation screen may be changed according to the construction data of the pile hole h0. Here, according to the excavation situation, the size of the input icon is changed. For example, when the input icon size in the case of a predetermined range with respect to the surrounding support layer reach depth is exceeded, the input icon is made smaller. Thereby, it is possible to prompt the checker to make a careful confirmation input.

[0060] Also, when the support layer reach depth predicted from the construction data and the input depth of the support reach by the determiner exceed a predetermined range, the input icon may also be made smaller. In this case, the control unit 41 predicts the support layer reach depth using the construction data. Also, in these cases, the display form of the confirmation input area may be changed to a color display pattern that prompts attention. Also, on this confirmation screen 500, the support layer depth is displayed in the order of the piles. The display method is not limited to two-dimensional display, and the support layer depth may be mapped and displayed three-dimensionally in the first direction and the second direction.

[0061] ·In the above embodiment, the control unit 41 of the management device 40 executes the determination processing of the support layer reach depth (step S22). Here, the control unit 41 may calculate and record the elapsed time from the output of the confirmation screen to the confirmation input at the position corresponding to the confirmation input position. And the shorter the elapsed time, the higher incentive (privilege) may be given to the checker. Thereby, it is possible to prompt a prompt confirmation input.

[0062] Next, the technical ideas that can be grasped from the above embodiment and the alternative example are added below. (a) The control unit Specify the penetration depth of the peripheral piles around the pile hole into the support layer, The construction management system according to claim 1, wherein, on the confirmation screen, the penetration depth of the specified peripheral pile into the support layer is arranged side by side with the penetration depth of the pile hole into the support layer.

(c) The construction management system according to claim 1 or any one of (a) and (b) above, wherein the control unit calculates and records the elapsed time from the output of the confirmation screen to the confirmation input at a position corresponding to the confirmation input position.
