Description

[Technical field]

[0001] The present disclosure relates to a construction support system and a construction support method for managing the construction of pile holes for installing piles. [Background technology]

[0002] When constructing a structure, a plurality of piles may be driven into the supporting layer, and the load of the structure may be supported by the supporting layer through the piles. For this reason, the pile holes into which the piles are inserted are made to reach the supporting layer. However, it is difficult to determine a qualitative judgment index for confirming the reaching of the supporting layer. Therefore, a method for judging the reaching of the pile holes to the supporting layer has been considered (for example, see Patent Documents 1 and 2). The drilling management system described in Patent Document 1 displays an output screen including a display area for displaying a depth-elapsed time graph, a depth-drilling speed graph, a depth-integrated current value graph, a depth-vibration analysis graph, a drilling speed judgment index value graph, and a vibration judgment index value graph. In addition, the ground hardness estimation system described in Patent Document 2 acquires values ​​measured by a drilling depth measuring instrument, a flow rate measuring instrument, a current measuring instrument, and a vibration measuring instrument. Then, a multiple regression equation is calculated by performing a multivariate analysis using the measured values ​​and the hardness index value as explanatory variables and objective variables.

[0004] When a pile constructor constructs piles, the construction site manager may manage the construction status. In this case, it is necessary to check the construction status according to the progress of pile construction.

[0008] Hereinafter, a specific embodiment of the construction support system and construction support method of the present embodiment will be described with reference to Figs. 1 to 8. 1 shows an excavator 10 as an excavation device for excavating a pile hole h0. The excavator 10 includes a base machine 10a, a mast 10b, and an auger machine 10c. The base machine 10a includes a lower traveling body including a crawler 10d, and an upper rotating body including an operation room 10e.

[0009] The mast 10b is erected on the base machine 10a. Wires for measuring depth and speed are provided inside the mast 10b. An auger machine 10c is attached to the mast 10b so that it can be raised and lowered. The auger machine 10c is equipped with a drive motor housed in a box and a drilling rod 10f that is driven and rotated by the drive motor. A drilling head 10g is attached to the tip (lower end) of the drilling rod 10f. The elevation of this drilling head 10g is controlled by an operator in the operation room 10e.

[0010] A drilling water supply device (not shown) that supplies drilling water to the drilling head 10g is connected to the drilling machine 10. The amount of drilling water is adjusted by the operator in the operation room 10e depending on the drilling conditions.

[0011] The excavator 10 is equipped with a measurement unit 11 (measurement device) that measures information that can be obtained during the construction of a pile, such as the excavation state and excavation conditions. This measurement unit 11 is connected to a management device 20. In this embodiment, the measurement unit 11 includes a depth measuring instrument 111, a flow rate measuring instrument 112, a current measuring instrument 113, and a vibration measuring instrument 114. Each measuring instrument (111 to 114) of the measurement unit 11 continuously performs measurement during excavation and transmits the measurement values ​​to the management device 20. This management device 20 is connected to a staff device 15.

[0012] The depth measuring device 111 measures the amount of wire let out from within the mast 10b. The depth measuring device 111 then measures the depth corresponding to the position of the drilling head 10g at each time in accordance with the amount of wire let out.

[0013] The flow rate meter 112 measures the injection flow rate (injection amount) of drilling water supplied from the drilling water supply device at each time. The current meter 113 measures the current value of the load current of the drive motor of the auger machine 10c at each time point.

[0014] The vibration measuring device 114 measures vibrations at the installation location at each time. In this embodiment, the vibration measuring device 114 is installed on the mast 10b, and measures vibration characteristics in three directions of the base machine 10a, namely, the front-rear direction, the left-right direction, and the up-down direction. The installation location of the vibration measuring device 114 is not limited to the mast 10b. For example, it may be installed in the operation room 10e, etc.

[0015] (Hardware configuration example) FIG. 2 shows an example of the hardware configuration of an information processing device H10 that functions as the person in charge device 15, the management device 20, and the like.

[0016] 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 H 15. Note that this hardware configuration is an example, and the information processing device H10 may include other hardware.

[0017] The communication device H11 is an interface that establishes a communication path with other devices and transmits and receives data. The input device H12 is a device that accepts input from the user.

[0018] 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 various functions of the person in charge device 15 and the management device 20. Examples of the storage device H14 include a ROM, a RAM, and a hard disk. The processor H15 controls each process in the person in charge device 15 and the management device 20 using the programs and data stored in the storage device H14.

[0019] (Explanation of the functions of the construction support system) Next, each function of the construction support system A1 will be described with reference to FIG.

[0020] The staff device 15 is a computer terminal used by a staff member in charge of managing the construction site. The management device 20 is a computer system that notifies the person in charge device 15 according to the excavation situation. The management device 20 includes a control unit 21, a pile information storage unit 22, a measurement information storage unit 23, and a notification condition storage unit 24.

[0021] The control unit 21 performs various processes (processing such as a setting stage, an acquisition stage, a notification stage, etc.). To this end, the control unit 21 functions as a setting unit 211, an acquisition unit 212, and a notification unit 213 by executing a construction support program stored in the memory.

[0022] The setting unit 211 records the notification conditions acquired from the person in charge device 15 in the notification condition storage unit 24 . The acquisition unit 212 acquires various measurement values ​​from the measurement unit 11. The acquisition unit 212 records the measurement values ​​acquired from the measurement unit 11 in association with each measurement time in the measurement information storage unit 23. Specifically, the acquisition unit 212 acquires the depth, the amount of injected water, the current value, and the vibration characteristics. In addition, in a hard stratum, the drilling head 10g may be pulled up once just before drilling. Therefore, the actual depth of the drilling head 10g does not necessarily increase monotonically with the elapsed time. Therefore, the acquisition unit 212 uses the measurement value of the substantial time period required for drilling by subtracting the period during which the drilling head 10g is pulled up or stopped from the total work time. The acquisition unit 212 records the depth range (start depth, end depth) in association with the drilling speed, the amount of injected water, the integral current value, and the vibration characteristics according to the measurement time. The acquisition unit 212 also acquires information on the amount of cement milk to be injected into the pile hole h0 after the pile hole h0 is excavated from the cement milk injection device. Cement milk is a foot protection liquid made by mixing cement and water. The notification unit 213 compares the construction status with the notification conditions, and notifies the person in charge device 15 if the notification conditions are met.

[0023] As shown in Fig. 3(a), pile management information 220 for each pile is recorded in the pile information storage unit 22. This pile management information 220 is recorded when a pile to be constructed is registered. This pile management information 220 records information on the site identifier, pile number, constructor, construction machine, design information, confirmation items, confirmation results, and confirmer.

[0024] The site identifier data area records information regarding an identifier for identifying the construction site where the piles are to be constructed. The pile number data area records information about an identifier for identifying the pile. The pile number identifies the pile hole h0 in which the pile is to be constructed.

[0025] The constructor data area records information about the company that will be constructing the piles. The construction machine data area records information about an identifier for identifying the excavator 10 that excavates the pile hole h0 in which the pile is to be placed.

[0026] The design information includes information regarding the pile hole diameter, the depth of the top of the foot protection, the predicted depth of the supporting layer, the depth of the pile tip, etc. The pile hole diameter is the diameter of the pile hole h0. The pile hole diameter includes the size of the expanded foot protection part.

[0027] The depth of the upper end of the foot protection is the depth of the upper end of the foot protection part which integrates the pile with the ground to strengthen the bearing capacity. The predicted bearing layer depth is the depth of the ground where the bearing layer is assumed to be. This predicted bearing layer depth is the depth predicted based on the boring survey and the condition of the surrounding pile holes h0. The pile tip depth is the depth at which the tip of the pile is placed, determined according to the predicted bearing layer depth.

[0028] The confirmation item data area and the confirmation result data area store information on the items that were confirmed and the confirmation results, respectively. As the confirmation items, contents corresponding to the notification conditions described later can be used. The confirming person data area records information related to an identifier that identifies the person in charge at the management company who made the confirmation.

[0029] As shown in Fig. 3(b), the measurement information storage unit 23 records measurement management information 230 in which measurement values ​​are recorded in association with the site identifier, pile number, and construction machine. The measurement management information 230 is recorded when acquired from the measurement unit 11. In this embodiment, values ​​related to the integral current value, excavation speed, water injection amount, and vibration are used for each depth. Furthermore, the measurement management information 230 records the amount of cement milk.

[0030] The site identifier data area records data regarding an identifier for identifying the construction site where the piles are to be constructed. The stake number data area records data regarding the number for identifying this stake.

[0031] The construction machine data area records information about an identifier for identifying the excavator 10 that excavates the pile hole h0 in which the pile is to be placed. In the depth data area, data on the depth of the measurement value obtained in this hole h0 is recorded. In this embodiment, for example, the data is recorded in units of 0.1 m, and the depth range (start depth, end depth) is recorded.

[0032] The integral current value data area, drilling speed data area, and water injection amount data area respectively record data regarding the integral current value calculated from the measured current value, the drilling speed of the drilling head 10g during drilling, and the injection flow rate of drilling water.

[0033] The vibration data area records data regarding the direction of vibration (front / back, left / right, up / down) and the amplitude at each vibration frequency. The cement milk amount data area records information regarding the amount of cement milk injected into the pile hole h0.

[0034] As shown in Fig. 3(c), the notification condition storage unit 24 records notification condition management information 240 for notifying the person in charge device 15 according to the construction status. This notification condition management information 240 is recorded when a contact is registered. This notification condition management information 240 records information related to the site identifier, pile number, contact, and notification conditions.

[0035] The site identifier data area records data regarding an identifier for identifying the construction site where the piles are to be constructed. The stake number data area records data regarding the number for identifying this stake.

[0036] The contact data area stores information for identifying the contact to which the notification is to be sent. In this embodiment, the terminal identification information of the person in charge device 15 is used to send the push notification. In the notification condition data area, information on the conditions for notifying the person in charge device 15 according to the construction situation is recorded.

[0037] As shown in FIG. 4, in this embodiment, the following construction status timings are used as notification conditions. [T1] Drilling begins This is the condition for notifying when the start of excavation is detected at the ground surface L1.

[0038] [T2] ​​When the top of the foot protection reaches the depth This is the condition for notification when the pile hole h0 reaches the depth L2 of the upper end of the foot protection near the supporting layer. [T3] When the predicted bearing layer depth is reached This is the condition for notifying when the pile hole h0 reaches the predicted depth L3 of the supporting layer.

[0039] [T4] When the depth of the pile tip is reached This is a condition to be notified when it is determined that the tip of the pile P1 in the pile hole h0 has reached the design depth L4.

[0040] [T5] When determining support layer reached This is a condition for notifying when it is determined that the pile hole h0 has reached the supporting layer based on the measurement information.

[0041] [T6] At administrator confirmation This is the condition to be notified when the administrator checks. [T7] Cement milk injection This is the condition for notifying when the amount of cement milk CM1 injected reaches the base consolidation depth or fills the entire pile hole h0.

[0042] [T8] When an abnormality is detected This is a condition for notifying when an abnormality is detected. For example, a notification is issued when the predicted bearing layer depth is reached and further excavation is continued to a predetermined depth, but it is not possible to determine whether the bearing layer has been reached.

[0043] (Notification setting process) The notification setting process will be described with reference to FIG. First, the control unit 21 of the management device 20 executes a condition setting process (step S11). Specifically, the setting unit 211 of the control unit 21 outputs a setting screen to the person in charge device 15. This setting screen includes setting fields for information on the site, piles, notification conditions, and contact information for which notification is desired. Here, at least one of [T1] Start of excavation to [T8] When an abnormality is detected is selected.

[0044] Next, the control unit 21 of the management device 20 executes a condition registration process (step S12). Specifically, the setting unit 211 of the control unit 21 acquires various information set on the setting screen from the person in charge device 15. Then, the setting unit 211 registers the notification condition management information 240 in the notification condition storage unit 24.

[0045] (Notification processing) The notification process will be described with reference to FIGS. First, the control unit 21 of the management device 20 executes a process of acquiring status information (step S21). Specifically, the acquisition unit 212 of the control unit 21 acquires measurement information from the measurement unit 11. In this case, the acquisition unit 212 acquires the measurement information for each excavation time together with the construction machine number and pile number of the excavator 10.

[0046] Next, the control unit 21 of the management device 20 executes a process of determining whether or not there is an abnormality (step S22). Specifically, the acquisition unit 212 of the control unit 21 determines whether or not the acquired measurement information is abnormal.

[0047] If it is determined that there is no abnormality (if "NO" in step S22), the control unit 21 of the management device 20 executes a condition determination process (step S23). Specifically, the notification unit 213 of the control unit 21 searches the notification condition storage unit 24 for notification condition management information 240 associated with the construction machine number and pile number of the excavator 10. Then, when the notification condition management information 240 is identified, the notification unit 213 identifies the construction status at the notification timing.

[0048] Next, the control unit 21 of the management device 20 executes a process of determining whether the conditions are satisfied (step S24). Specifically, the notification unit 213 of the control unit 21 uses the pile management information 220 and the measurement management information 230 to determine whether the construction status of the notification conditions is satisfied.

[0049] For example, if the notification condition is set to [T1] start of excavation, the notification unit 213 determines that the condition is satisfied when recording of depth begins in the measurement management information 230 associated with the construction machine and pile number in the measurement information storage unit 23.

[0050] In addition, when [T2] When the footing top end depth is reached to [T4] When the pile tip depth is reached is set, the notification unit 213 acquires the footing top end depth, the predicted bearing layer depth, and the pile tip depth from the pile management information 220 associated with the construction machine and pile number in the pile information storage unit 22. Then, the notification unit 213 determines that the conditions are satisfied when the current excavation depth reaches the footing top end depth, the predicted bearing layer depth, and the pile tip depth for the first time.

[0051] In addition, when the time of [T5] bearing layer arrival judgment is set, the notification unit 213 judges that the condition is satisfied when it judges that the pile hole h0 has reached the bearing layer based on the measurement information. For example, the technology described in Patent Documents 1 and 2 can be used for this bearing layer arrival.

[0052] In addition, if [T6] Time of administrator confirmation is set, the notification unit 213 determines that the condition is satisfied when the confirmation result is recorded in the pile management information 220 associated with the construction machine and pile number.

[0053] Furthermore, when [T7] cement milk injection is set, the notification unit 213 calculates the required amount of cement milk to meet the foot protection depth and the required amount of cement milk to fill the entire pile hole h0 based on the design information of the pile management information 220. In this case, the required amount is calculated, for example, from the volume according to the pile diameter and depth (distance from the pile bottom) in the design information. Then, the acquisition unit 212 determines that the condition is satisfied when the injection amount of cement milk acquired from the cement milk injection device reaches the required amount.

[0054] If it is determined that the condition is not satisfied ("NO" in step S24), the control unit 21 of the management device 20 returns to the status information acquisition process (step S21). On the other hand, if it is determined that there is an abnormality (if "YES" in step S22) or if it is determined that the condition is satisfied (if "YES" in step S24), the control unit 21 of the management device 20 executes a notification process (step S25). Specifically, the notification unit 213 of the control unit 21 transmits a message indicating that the notification condition is satisfied to the contact information recorded in the notification condition storage unit 24 by push notification.

[0055] As shown in Fig. 7, for example, when the predicted bearing layer depth is reached, a message 400 is sent to the display device H13 of the person in charge device 15. In addition to information on the date and time, pile number, builder, and construction machine, this message 400 also contains a link 401 for checking the measurement information. To check the measurement information, the link 401 is selected. In this case, the person in charge device 15 sends a measurement information request to the management device 20. The measurement information request includes the identification information of the excavator and the identification information of the pile.

[0056] In this case, the control unit 21 of the management device 20 acquires the measurement management information 230 including the identification information of the excavator and the identification information of the pile of the measurement information request from the measurement information storage unit 23. Then, a confirmation screen including the measurement management information 230 is generated and output to the display device H13 of the staff device 15.

[0057] In this case, as shown in Fig. 8, the confirmation screen 500 includes a contractor column 501, a pile number column 502, a depth column 511, an excavation time column 512, a current column 513, an integral current column 514, a vibration column 515, and a water volume column (not shown). In this vibration column 515, a spectrogram SP0 is displayed in which the horizontal axis is vibration frequency and the vertical axis is a frequency distribution of depth. In this case, the person in charge checks the depth, current value, water volume, vibration status, etc. to determine whether the bearing layer has been reached.

[0058] Then, the person in charge who has confirmed the situation inputs the confirmation result to the person in charge device 15. In this case, the control unit 21 records information on the confirmation item, confirmation result, and confirmer in the pile management information 220 in accordance with the notification conditions of the notified message 400. In this case, the notification unit 213 issues a notification in accordance with the settings at the time of the manager's confirmation [T6].

[0059] (Operation of the embodiment) The control unit 21 of the management device 20 determines whether the notification condition is satisfied, and a message corresponding to the notification condition is notified to the person in charge device 15.

[0060] According to this embodiment, the following effects can be obtained. (1) In this embodiment, notification condition management information 240 for sending notifications to contact persons is recorded in the notification condition storage unit 24. This allows the desired construction status to be checked in a timely manner.

[0061] (2) In this embodiment, the control unit 21 of the management device 20 executes a condition setting process (step S11), which allows a notification to be obtained at a timing according to the construction status desired by the person in charge.

[0062] (3) In this embodiment, the control unit 21 of the management device 20 executes a process for acquiring status information (step S21), which makes it possible to determine the timing of notification depending on the construction status.

[0063] (4) In this embodiment, the control unit 21 of the management device 20 executes a process for determining whether or not there is an abnormality (step S22). As a result, if there is a problem with the construction status, it is possible to promptly call attention to it.

[0064] (5) In this embodiment, the control unit 21 of the management device 20 executes a determination process as to whether or not the condition is satisfied (step S24). If it is determined that the condition is satisfied (YES in step S24), the control unit 21 of the management device 20 executes a notification process (step S25).

[0065] Here, if the notification condition is set to [T1] start of excavation, the start of construction can be known in a timely manner. In addition, if [T2] is the time when the top depth of the foot reinforcement is reached, [T3] is the time when the predicted supporting layer depth is reached, and [T4] is the time when the pile tip depth is reached are set, the progress of construction can be grasped in a timely manner. In addition, if the time for determining whether or not the support layer has been reached (T5) is set, the support layer reach can be confirmed in a timely manner.

[0066] In addition, if [T6] Administrator confirmation time is set, the administrator's confirmation status can be known in a timely manner. In addition, when [T7] cement milk injection is set, the cement milk injection status can be checked in a timely manner.

[0067] (6) In this embodiment, when the link 401 is selected, the control unit 21 of the management device 20 outputs a confirmation screen to the display device H13 of the staff device 15. This allows the staff to check the measurement information.

[0068] This embodiment can be modified as follows: This embodiment and the following modifications can be combined with each other to the extent that there is no technical contradiction. In the above embodiment, the measurement information storage unit 23 records measurement management information 230 that records measurement values ​​in association with the site identifier, pile number, and construction machine. The measurement management information 230 records values ​​related to the integral current value, excavation speed, water injection amount, and vibration for each depth. Furthermore, the measurement management information 230 records the amount of cement milk. The information recorded in the measurement management information 230 is not limited to these. Some of these or other information may be recorded.

[0069] In the above embodiment, when it is determined that the conditions are satisfied ("YES" in step S24), the control unit 21 of the management device 20 executes a notification process (step S25). In this case, a message indicating that the notification conditions are satisfied is sent by push notification. In addition to information on the date and time, pile number, constructor, and construction machine, this message 400 includes a link 401 for checking the measurement information. The information included in the message 400 is not limited to these.

[0070] For example, the message may include an image or a link to obtain the image. In this case, a camera capable of photographing the construction site is installed. Then, the control unit 21 of the management device 20 obtains live images from the camera and displays them on the display device H13 of the person in charge device 15. Information on other piles may also be displayed. For example, information on surrounding piles that have been determined or confirmed to have reached the bearing layer (e.g., the depth to which the pile has reached the bearing layer) may be included. This information allows efficient comparison of the pile under construction with the surrounding piles.

[0071] In the above embodiment, the notification conditions are set as [T1] start of excavation to [T8] when an abnormality is detected. The notification conditions are not limited to these. For example, they may be set at any depth. Moreover, the notification condition may be set using a measurement value recorded in the measurement information storage unit 23. In this case, a plurality of types of measurement values ​​may be combined to configure the notification condition.

[0072] In the above embodiment, the notification condition storage unit 24 records notification condition management information 240 for sending notifications to contacts. This notification condition management information 240 records the site identifier, pile number, contacts, and information related to the notification conditions. Here, the contacts may be initially set according to the notification conditions. For example, the pile management information 220 may record contact information of a manager, and when an abnormality is detected [T8], a push notification may be sent to the manager's staff device 15.
