Description

[Technical Field]

[0001] The present invention relates to a concrete pouring monitoring system, a guide device, and a concrete pouring monitoring method. [Background technology]

[0002] Various techniques have been proposed for accurately placing piles or other target components at predetermined positions and directions. For example, Patent Document 1 proposes a driving ruler that slidably clamps the pile at two locations along its length to prevent the pile from wobbling when driven by a vibratory pile driver, thereby improving the driving accuracy of the pile. Patent Document 2 also proposes a casing guide device that guides the casing in a constant driving direction while maintaining its straightness by contacting multiple rollers with the outer periphery of the casing. Conventionally, the target component is aligned with a portion of the guide material, and workers use measuring equipment to measure the inclination and position of the target component from two directions during driving to constantly check the driving accuracy.

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2009-264003 [Patent Document 2] Japanese Patent Application Laid-Open No. 2014-070469 Summary of the Invention [Problem to be solved by the invention]

[0004] However, because the target concrete moves during the pouring process, it has not been fixed or restrained to the guiding material in the past, but has simply been placed along the guiding material, making it prone to tilting or displacement (for example, pile misalignment) during pouring. Furthermore, if actual tilting or displacement is detected through measurement, the concrete must be redone or corrected, which can be a significant workload if the concrete has already been poured underground. Therefore, there has been a demand for a system that can detect signs of tilting or displacement of the target concrete in advance.

[0005] The present invention has been made in consideration of the above circumstances, and aims to provide a pouring monitoring system, a guide device, and a pouring monitoring method that can further improve pouring accuracy by monitoring for signs of tilt or positional deviation of the object to be poured. [Means for solving the problem]

[0006] The present invention has been made to solve the above-mentioned problems, and one aspect of the present invention is a pouring monitoring system comprising a support member that supports the target member to be poured, a reaction force measuring unit that measures the reaction force acting on the support member, and a providing unit that provides a user with information including the reaction force information measured by the reaction force measuring unit.

[0007] Another aspect of the present invention is a guide device comprising a support member that supports the target component to be poured, a reaction force measuring unit that measures the reaction force acting on the support member, and a communication unit that transmits information including the reaction force information measured by the reaction force measuring unit to an external device.

[0008] Another aspect of the present invention is a pouring monitoring method that measures the reaction force acting on a support member that supports the target member to be poured, and provides information including the measured reaction force information to a user. [Effects of the Invention]

[0009] According to the present invention, pouring accuracy can be further improved by monitoring signs of tilt or misalignment of the object to be poured. [Brief explanation of the drawings]

[0011] Hereinafter, embodiments of the concrete pouring monitoring system, guide device, and concrete pouring monitoring method of the present invention will be described with reference to the drawings.

[0012] <Outline of the pouring monitoring system> FIG. 1 is a diagram illustrating an example of a schematic configuration of a concrete pouring monitoring system according to an embodiment. The concrete pouring monitoring system 1 illustrated in FIG. 1 includes, for example, a guide device 100, a server device 200, and a terminal device 300, which are installed at a construction site (e.g., a concrete pouring site) 10. The guide device 100, the server device 200, and the terminal device 300 are communicatively connected via, for example, a network NW. The network NW may be, for example, a wide area network (WAN), a local area network (LAN), the Internet, a Wi-Fi network, a cellular network, or the like. Note that, for convenience of explanation, the example in FIG. 1 illustrates only one of the above components, but the system may include multiple components of at least one of them. In this case, for example, the server device 200 communicates with multiple guide devices 100 or multiple terminal devices 300.

[0013] The guide device 100 supports a steel pipe sheet pile 30 arranged along a portion of a guide material 20 installed at a construction site 10. The steel pipe sheet pile 30 is an example of a "target object to be driven." In the embodiment, the target object to be driven may be a cylindrical, columnar, or plate-shaped member such as a pile, a core, or a steel sheet pile, instead of the steel pipe sheet pile 30. In the example of FIG. 1 , the steel pipe sheet pile 30 is driven vertically (the driving direction in the figure) by a driving machine or the like, and is installed by being embedded in the ground to a predetermined position. In addition, the steel pipe sheet pile 30 has joints 32-1 and 32-2 on both sides, which can be connected (engaged, engaged) with the joints of other steel pipes in the arrangement, allowing the steel pipe sheet piles 30 to be arranged without gaps. The guide device 100 measures the reaction force from the supported steel pipe sheet pile 30 and transmits the measurement information and the like to an external device (for example, a server device 200, a terminal device 300) via a network NW. The specific structure and configuration of the guide device 100 will be described later.

[0014] The server device 200 receives and manages information received from the guide device 100 via the network NW. The server device 200 may be, for example, a general-purpose personal computer (PC) or a cloud server configured by cloud computing including one or more information processing devices. For example, the server device 200 stores measurement information received from the guide device 100 in a memory unit, detects signs of inclination or misalignment of the steel pipe sheet pile 30 based on the measurement information, and provides information to the user of the terminal device 300. The server device 200 may also output information to its output unit. The server device 200 may also acquire various information from other devices present at the construction site 10 via the network NW and centrally manage the information. For example, the server device 200 may acquire and manage measurement information from measuring instruments that measure the actual inclination or misalignment of the steel pipe sheet pile 30 to be driven, or receive and manage information entered by the user via the terminal device 300. The configuration of the server device 200 will be described later.

[0015] The terminal device 300 is a communication terminal used by a user (e.g., an operator operating a heavy machine that drives the steel pipe sheet piles 30, a manager of the construction site 10, a worker, etc.). The terminal device 300 is, for example, but not limited to, a tablet terminal, a smartphone, a display terminal (on-board display device) installed in the operation room of the heavy machine, etc. The terminal device 300 provides information to the user by outputting information received from the server device 200 as images or sounds using an output unit such as a display or speaker. The terminal device 300 may also directly acquire and output measurement information, etc. from the guide device 100, or detect signs of inclination or misalignment of the steel pipe sheet piles 30. The terminal device 300 may also communicate with devices other than the guide device 100 and the server device 200 via the network NW. The configuration of the terminal device 300 will be described later.

[0016] <Guide device> Next, the configuration of the guide device 100 (mainly structural parts) will be described with reference to the drawings. FIG. 2 is a diagram for explaining the installation status of the guide device 100. In the example of FIG. 2, a plurality of guide piles (vertical members) 22 extending vertically from the ground are installed at the construction site 10 as guide materials 20. Furthermore, guide frames (horizontal members) 24-1 and 24-2 are installed, supported by each guide pile 22 and formed along the planned direction in which a plurality of steel pipe sheet piles 30 are to be arranged side by side. In the example of FIG. 2, the guide frames 24-1 and 24-2 are both formed in a ring shape along the arrangement direction of the plurality of steel pipe sheet piles 30 to be installed, and are both installed horizontally. Also, in the example of FIG. 2, the guide frame 24-2 is installed inside the guide frame 24-1. Also, in the embodiment, as shown in FIG. 2, the guide frames 24-1 and 24-2 are provided in two upper and lower stages at different heights. Hereinafter, when describing the guide frames 24 separately, the upper guide frames will be referred to as "guide frames 24-1a, 24-2a" and the lower guide frames will be referred to as "guide frames 24-1b, 24-2b." The steel pipe sheet pile 30 to be driven is supported by the outer circumferential surface of the steel pipe sheet pile 30 abutting against the inside of the guide frames 24-1a, 24-1b and the outside of the guide frames 24-2a, 24-2b.

[0017] Here, the guide device 100 is supported by the guide frame 24 and is installed so as to abut against two joints 32-1 and 32-2 provided on the steel pipe sheet pile 30 to support the steel pipe sheet pile 30 (joints 32-1 and 32-2). For example, the guide device 100 is installed at multiple locations (at least two locations) above and below each of the joints 32-1 and 32-2. In the example of FIG. 2, the guide devices 100 are installed at two different locations in the vertical direction (casting direction) for each of the joints 32-1 and 32-2. In the following description, when the guide devices 100 are distinguished from one another, the guide device 100 installed at the upper level relative to the joint 32-1 will be referred to as the "guide device 100a," and the guide device 100 installed at the lower level will be referred to as the "guide device 100b." In addition, the guide device 100 installed in the upper stage relative to the joint 32-2 will be referred to as "guide device 100c," and the guide device 100 installed in the lower stage will be referred to as "guide device 100d." The guide devices 100a and 100c are supported (fixed) by guide frames 24-1a and 24-2a, and the guide devices 100b and 100d are supported (fixed) by guide frames 24-1b and 24-2b.

[0018] FIG. 3 is a diagram illustrating how the guide device 100 supports the joint 32. The example in FIG. 3 shows a top view of the steel pipe sheet pile 30. As shown in FIG. 3, the guide device 100a includes two guide rollers 110a-1 and 100a-2 that sandwich the joint 32-1, which protrudes from the annular ring of the steel pipe sheet pile 30, from the left and right. The guide rollers 110a-1 and 110a-2 are examples of "support members" that support the steel pipe sheet pile 30. The guide rollers 110a-1 and 110a-2 are arranged to abut against the joint 32-1 while rotating relative to the movement of the steel pipe sheet pile 30 in the driving direction (driving direction, −Z direction in the figure).

[0019] The reaction force measuring units 120a-1 and 120a-2 measure the reaction force acting on the guide rollers 110a-1 and 110a-2 via the joint 32-1. The reaction force measuring units 120a-1 and 120a-2 are, for example, strain sensors. For example, each of the reaction force measuring units 120a-1 and 120a-2 measures the amount of deformation (amount of strain) of a rigid body (rigid material) supporting the guide rollers 110a-1 and 110a-2 when subjected to a force (external force) from the outside (steel pipe sheet pile 30) using a strain sensor, and acquires the reaction force acting on the guide rollers 110a-1 and 110a-2 according to the measured amount of strain. Alternatively, the reaction force measuring units 120a-1 and 120a-2 may be pressure sensors that measure pressure on the guide rollers 110a-1 and 110a-2 (or the rotation axis of the guide roller 110). In this case, each of the reaction force measuring units 120a-1 and 120a-2 acquires the measured pressure as reaction force information.

[0020] 3 also includes two guide rollers 110c-1 and 110c-2 that sandwich the joint 32-2 from the left and right, and reaction force measuring units 120c-1 and 120c-2 that measure reaction forces acting on the guide rollers 110c-1 and 100c-2. The guide rollers 110c-1 and 110c-2 support the steel pipe sheet pile 30 by sandwiching the joint 32-2. The reaction force measuring units 120c-1 and 120c-2 measure the reaction forces acting on the guide rollers 110c-1 and 110c-2 by the joint 32-1.

[0021] Figures 4 and 5 are diagrams (parts 1 and 2) for explaining how joint 32 is supported by guide devices provided in two stages, upper and lower. Figure 4 is a view looking in the direction in which joint 32-1 exists (the -Y axis direction in the figure), and Figure 5 is a view looking in the direction in which joint 32-2 exists (the Y axis direction in the figure). In Figure 4, the left side shows the inside of the annular guide frame 24 (guide frames 24-1a, 24-2a, 24-1b, 24-2b), and the right side shows the outside of the annular guide frame 24. Also, in Figure 5, the left side shows the outside of the annular guide frame 24, and the right side shows the inside of the annular guide frame 24. In addition, in the examples of Figures 4 and 5, the guide frame 24, guide devices 100, etc. are shown in cross-sectional views, etc., to clarify the positional relationship between the four guide devices 100a to 100d, which are installed in two tiers, one above the other, for each of the joints 32-1 and 32-2 on both sides of the steel pipe sheet pile 30, and the guide rollers 110 and reaction force measuring units 120 provided on each of the guide devices 100a to 100d.

[0022] In the example of Fig. 4, a guide device 100a is installed in the upper stage of the steel pipe sheet pile 30 so as to be supported by guide frames 24-1a and 24-2a, and a guide device 100b is installed in the lower stage so as to be supported by guide frames 24-1b and 24-2b. The guide device 100b may be adjusted by an adjustment member 26 so that the height distance D1 between the guide device 100a in the upper stage and the guide device 100b becomes a predetermined distance. The predetermined distance may be a fixed distance or may be a variable distance depending on the length, size, type, material, etc. of the steel pipe sheet pile 30.

[0023] The guide device 100a includes a pair of guide rollers 110a-1 and 110a-2 disposed at opposing positions to support the joint 32-1 of the steel pipe sheet pile 30 by sandwiching it from both sides, and reaction force measuring units 120a-1 and 120a-2 that measure the reaction forces acting on the guide rollers 110a-1 and 110a-2, respectively. Similarly, the guide device 100b includes a pair of guide rollers 110b-1 and 110b-2 that support the joint 32-1 of the steel pipe sheet pile 30 by sandwiching it from both sides, and reaction force measuring units 120b-1 and 120b-2 that measure the reaction forces acting on the guide rollers 110b-1 and 110b-2, respectively.

[0024] 5, a guide device 100c is installed in the upper stage of the steel pipe sheet pile 30 so as to be supported by guide frames 24-1a and 24-2a, and a guide device 100b is installed in the lower stage so as to be supported by guide frames 24-1b and 24-2b. Note that the height direction distance between the guide device 100d and the upper guide device 100c may be adjusted by an adjustment member 26.

[0025] The guide device 100c includes a pair of guide rollers 110c-1 and 110c-2 disposed at opposing positions to support the joint 32-2 of the steel pipe sheet pile 30 by sandwiching it from both sides, and reaction force measuring units 120c-1 and 120c-2 that measure reaction forces acting on the guide rollers 110c-1 and 110c-2, respectively. Similarly, the guide device 100d includes a pair of guide rollers 110d-1 and 110d-2 that support the joint 32-2 of the steel pipe sheet pile 30 by sandwiching it from both sides, and reaction force measuring units 120d-1 and 120d-2 that measure reaction forces acting on the guide rollers 110d-1 and 110d-2, respectively.

[0026] Here, the reaction force acting on each of the guide rollers 110 shown in Figures 4 and 5 is measured at a predetermined timing or period by the reaction force measuring unit 120, and the measurement information, etc. is transmitted to the server device 200 and the terminal device 300 via the network NW. When the guide rollers 110 of the guide device 100 are initially installed to support (contact) the steel pipe sheet pile 30 (joint 32), a certain amount of (very small) reaction force is measured, but this value is treated as an initial value. When the guide rollers 110 are installed to support the steel pipe sheet pile 30, the guide rollers 110 are installed so that the reaction force value measured by the reaction force measuring unit 120 is equal to or greater than a predetermined value. This makes it possible to more reliably support the steel pipe sheet pile 30 (joint 32) and more accurately detect signs of inclination or displacement of the steel pipe sheet pile 30 using the reaction force.

[0027] For example, when the reaction force acting on one of the pair of guide rollers 110 increases, the reaction force acting on the other guide roller decreases (or becomes zero). For example, when a force is applied to the steel pipe sheet pile 30 shown in FIG. 4 in the direction of arrow A during the driving of the steel pipe sheet pile 30, the reaction force measured by the reaction force measuring unit 120a-2 for the guide roller 110a-2 increases, and the reaction force measured by the reaction force measuring unit 120a-1 for the opposite guide roller 110a-1 decreases. Furthermore, when a force is applied to the steel pipe sheet pile 30 shown in FIG. 4 in the direction of arrow B during the driving of the steel pipe sheet pile 30, the reaction force measured by the reaction force measuring unit 120b-1 for the guide roller 110b-1 increases, and the reaction force measured by the reaction force measuring unit 120b-2 for the opposite guide roller 110b-2 decreases.

[0028] Similarly, when a force is applied to the steel pipe sheet pile 30 shown in FIG. 5 in the direction of arrow C during installation, the reaction force measured by the reaction force measuring unit 120c-2 for the guide roller 110c-2 increases, while the reaction force measured by the reaction force measuring unit 120c-1 for the opposite guide roller 110c-1 decreases. When a force is applied to the steel pipe sheet pile 30 shown in FIG. 5 in the direction of arrow D during installation, the reaction force measured by the reaction force measuring unit 120d-1 for the guide roller 110d-1 increases, while the reaction force measured by the reaction force measuring unit 120d-2 for the opposite guide roller 110d-2 decreases. The reaction forces measured by each of the eight reaction force measuring units 120 shown in FIGS. 4 and 5 change depending on the magnitude and direction of the forces indicated by arrows A to D in FIGS. 4 and 5.

[0029] When the above-mentioned reaction force becomes large (when the reaction force value exceeds the upper limit value), the steel pipe sheet pile 30 actually tilts or shifts in position. Therefore, by using this reaction force value, it is possible to accurately predict the possibility of tilting or shifting of the steel pipe sheet pile 30 even when no tilt or shifting actually occurs. Therefore, by providing the user with reaction force information, it is possible to perform pouring control that reduces the reaction force, thereby preventing the actual occurrence of tilting or shifting. This allows the steel pipe sheet pile 30 to be poured with higher accuracy. In addition, since the amount of work required for redoing or correcting pouring can be reduced, the burden on the worker can be reduced and work efficiency can be improved.

[0030] <Functional configuration of the guide device> Next, the functional configuration of the guide device 100 will be described. Since the functional configurations of the guide devices 100a to 100d of the embodiments are the same, they will be collectively described as the guide device 100. Fig. 6 is a diagram showing an example of the functional configuration of the guide device 100. In addition to the above-described guide roller 110 and reaction force measuring unit 120, the guide device 100 includes, for example, a communication unit 130, a control unit 140, and a storage unit 150.

[0031] The guide rollers 110 are rollers that support the steel pipe sheet pile 30 to be driven in a state in which they sandwich the steel pipe sheet pile 30 from opposite directions as described above, and rotate while contacting the steel pipe sheet pile 30 as the steel pipe sheet pile 30 moves in the driving direction (for example, the vertical direction). The reaction force measuring unit 120 measures the reaction force acting on each of the two guide rollers 110 provided in the guide device 100 as described above.

[0032] The communication unit 130 communicates with the server device 200, the terminal device 300, and other terminals via the network NW.

[0033] The control unit 140 is realized, for example, by a hardware processor such as a CPU (Central Processing Unit) executing a program (software). Some or all of these components may be realized by hardware (including circuitry) such as an LSI (Large Scale Integration), an ASIC (Application Specific Integrated Circuit), an FPGA (Field-Programmable Gate Array), or a GPU (Graphics Processing Unit), or may be realized by a combination of software and hardware. The program may be stored in advance in a storage device (a storage device having a non-transitory storage medium) such as an HDD (Hard Disk Drive) or flash memory of the guiding device 100, or may be stored in a removable storage medium such as a memory card or USB (Universal Serial Bus) memory, and installed in the guiding device 100 by attaching the storage medium (non-transitory storage medium) to the guiding device 100.

[0034] The control unit 140 stores the reaction force information measured by the reaction force measuring unit 120 of the guide device 100 as measurement information 152 in the storage unit 150 at a predetermined period or timing, and transmits the measurement information 152 to the server device 200 or the terminal device 300 via the communication unit 130. The control unit 140 may add identification information for identifying the guide device 100, identification information for identifying the guide rollers 110, time information, etc. to the measurement information 152. Furthermore, if the guide device 100 is provided with a GNSS (Global Navigation Satellite System) receiver or the like, the control unit 140 may add position information of the guide device 100 acquired by the GNSS receiver to the measurement information 152.

[0035] The storage unit 150 may be realized by the various storage devices described above, or a solid state drive (SSD), an electrically erasable programmable read only memory (EEPROM), a read only memory (ROM), a random access memory (RAM), etc. The storage unit 150 stores, for example, measurement information 152, programs, and various other information.

[0036] In the embodiment, each of the above-described guide devices 100a to 100d may be integrated into one guide device 100. In that case, there may be only one communication unit 130, control unit 140, and storage unit 150, and the control unit 140 aggregates measurement information from a reaction force measurement unit 120 that measures the reaction force acting on each guide roller 110 of the guide devices 100a to 100d (a total of eight guide rollers), and transmits the information to the server device 200 or the terminal device 300 via the communication unit 130.

[0037] <Server device functional configuration> Next, the functional configuration of the server device 200 will be described with reference to the drawings. FIG. 7 is a diagram showing an example of the functional configuration of the server device 200. The server device 200 includes, for example, a communication unit 210, an input unit 220, an output unit 230, a management unit 240, a provision unit 250, a control unit 260, and a storage unit 270. The management unit 240, the provision unit 250, and the control unit 260 are realized by, for example, a hardware processor such as a CPU executing a program (software). Furthermore, some or all of these components may be realized by hardware (including circuitry) such as an LSI, ASIC, FPGA, or GPU, or may be realized by a combination of software and hardware. The program may be stored in advance in a storage device (a storage device having a non-transitory storage medium) such as an HDD or flash memory of the server device 200, or may be stored in a removable storage medium such as a memory card, USB memory, or CD-ROM, and installed in the server device 200 by attaching the storage medium (non-transitory storage medium) to the server device 200.

[0038] The communication unit 210 communicates with the guide device 100, the terminal device 300, and other terminals via the network NW. The input unit 220 receives input from the user of the server device 200 by operating various keys, buttons, etc., for example. The input unit 220 may also include a microphone that receives voice input from the user. The output unit 230 includes, for example, a display and a speaker. The display is, for example, an LCD (Liquid Crystal Display) or an organic EL (Electro Luminescence) display. The display displays various types of information in the embodiment. The speaker outputs predetermined sounds. The input unit 220 and the output unit 230 may be integrated as a touch panel to enable input and output.

[0039] The management unit 240 manages the measurement information 152 acquired from the guide device 100 and manages information about users who use the services provided by the concrete pouring monitoring system 1. For example, the management unit 240 stores and manages the measurement information 152 in a measurement information database 272, and stores and manages personal information of users, address information of terminal devices 300 owned by users, and work status of users in a user information database 274. The measurement information database 272 may also manage past measurement information of the guide device 100. The management unit 240 may also acquire other measuring devices present at the construction site 10 (for example, a weighing machine, a GNSS receiver, an inclinometer, a camera, etc. that measure the actual position and inclination of the steel pipe sheet pile 30) and store the information in the measurement information database 272.

[0040] The providing unit 250 provides information to the user by outputting information managed by the management unit 240, information processed by the control unit 260, etc. to the output unit 230 or transmitting the information to the terminal device 300. For example, the providing unit 250 generates an image including reaction force information measured by the guide device 100 and provides the generated image to predetermined target users among the users registered in the user information DB 274. Furthermore, when the control unit 260 detects a sign of tilt or misalignment of the steel pipe sheet pile 30 or when tilt or misalignment actually occurs, the providing unit 250 generates an image showing corresponding warning information and provides the generated image to the target users. Furthermore, the providing unit 250 may provide a sound (warning sound) or the like corresponding to the image information to the user.

[0041] The control unit 260 controls the overall components of the server device 200. For example, the control unit 260 controls the transmission and reception of information by the communication unit 210, causes the output unit 230 to output information input by the input unit 220 and information stored in the storage unit 270, and controls the execution of processes by the management unit 240 and the provision unit 250.

[0042] For example, when the reaction force value acquired from the guide device 100 of the steel pipe sheet pile 30 being driven changes due to the influence of auctions or the like and becomes equal to or greater than a predetermined threshold for detecting signs, the control unit 260 detects that there is a sign (sign, precursor) of tilt and / or displacement of the steel pipe sheet pile 30. The threshold for detecting signs may be a fixed value or may be a variable value depending on the type, size, and shape of the target material to be driven. The threshold for detecting signs may be adjusted based on the initial value of the reaction force when the guide device 100 is first installed. Furthermore, the control unit 260 may detect a sign of tilt and / or displacement by comparing the amount of change in the reaction force value from the initial value with the threshold for detecting signs.

[0043] Furthermore, the control unit 140 may detect a sign of either tilt or misalignment, or both, based on the relative positions of the guide rollers 110 installed at eight locations and the reaction force value acting on each guide roller 110 (in other words, the direction in which an external force is being applied). For example, the control unit 260 may detect a sign of misalignment when the direction of the reaction force acting on the guide roller 110 installed at the upper tier and the direction of the reaction force acting on the guide roller 110 installed at the lower tier are the same, and may detect a sign of tilt when the directions are opposite. Furthermore, the control unit 260 may detect a sign of both tilt and misalignment when the difference between the reaction force value that is equal to or greater than the sign detection threshold and the sign detection threshold is equal to or greater than a predetermined value.

[0044] Furthermore, the control unit 260 may derive the amount of change or the trend of change in the reaction force over a predetermined time period, including past measurement results, based on the measurement information DB 272 stored in the storage unit 270, and detect a sign of tilt and / or misalignment based on the derived result. For example, the control unit 260 detects a sign of tilt or misalignment when the state in which the reaction force value is increasing is equal to or greater than a threshold value.

[0045] The providing unit 250 may provide warning information to the user not only when the tilt or misalignment of the steel pipe sheet pile 30 is actually detected by other measuring devices or the like to be equal to or greater than an upper limit, but also when a sign of tilt or misalignment is detected, as preliminary warning information. In this case, the providing unit 250 may provide the warning information and the preliminary warning information to the user in different ways. Examples of different ways include highlighting the warning information more than the preliminary warning information (e.g., displaying a highly visible color or flashing), making the warning sound louder, or using different types of images or sounds. This allows the user to distinguish between the occurrence of tilt or misalignment in the steel pipe sheet pile 30 during casting and the presence of a sign of tilt or misalignment, thereby enabling more appropriate work to be performed depending on the respective situations. This further improves casting accuracy.

[0046] Furthermore, the control unit 260 may predict trends in concrete pouring for the entire construction site 10 based on measurement information not only for the steel pipe sheet pile 30 being poured but also for other steel pipes that have already been poured, and may provide the prediction results to the user via the providing unit 250. Examples of trends in concrete pouring include the tilt direction, the direction of misalignment, and the timing from the start of pouring until the occurrence of tilt or misalignment. This allows for more appropriate concrete pouring operations to be performed based on past pouring information, thereby suppressing the occurrence of tilt or misalignment and further improving concrete pouring accuracy.

[0047] The storage unit 270 may be realized by the various storage devices described above, or an SSD, an EEPROM, a ROM, a RAM, etc. The storage unit 270 stores, for example, a measurement information DB 272, a user information DB 274, programs, and various other information.

[0048] <Functional configuration of terminal device> Next, the functional configuration of the terminal device 300 will be described with reference to the drawings. FIG. 8 is a diagram illustrating an example of the functional configuration of the terminal device 300. The terminal device 300 includes, for example, a communication unit 310, an input unit 320, an output unit 330, an application execution unit 340, a control unit 350, and a storage unit 360. The application execution unit 340 and the control unit 350 are realized by, for example, a hardware processor such as a CPU executing a program (software). Some or all of these components may be realized by hardware (including circuitry) such as an LSI, ASIC, FPGA, or GPU, or may be realized by a combination of software and hardware. The program may be stored in advance in a storage device (a storage device having a non-transitory storage medium) such as an HDD or flash memory of the terminal device 300, or may be stored in a removable storage medium such as a memory card, USB memory, or CD-ROM, and installed in the terminal device 300 by inserting the storage medium (non-transitory storage medium) into the terminal device 300.

[0049] The communication unit 310 communicates with the guide device 100, the server device 200, and other terminals via the network NW. The input unit 320 accepts input from the user of the terminal device 300 by operating various keys, buttons, etc., for example. The input unit 320 may also include a microphone that accepts voice input from the user. The output unit 330 includes, for example, a display and a speaker. The display is, for example, an LCD or an organic EL display. The display displays various types of information in the embodiments. The speaker outputs predetermined sounds. The input unit 320 and the output unit 330 may be integrated into a touch panel to enable input and output.

[0050] The application execution unit 340 is realized, for example, by executing a pouring monitoring application 352 stored in the storage unit 360. The pouring monitoring application 352 is, for example, downloaded from an external device via the network NW and installed on the terminal device 300. The pouring monitoring application 352 is, for example, application software that causes the output unit 330 to output information provided by the server device 200. The pouring monitoring application 352 may also perform processing similar to that performed by the providing unit 250 or the control unit 260 described above based on measurement information (e.g., reaction force information) acquired from the guide device 100, and output the processing result from the output unit 330 or transmit the processing result to the server device 200 via the network NW. In this case, the application execution unit 340 functions as the providing unit 250 or the control unit 260.

[0051] The control unit 350 controls all of the components included in the terminal device 300. For example, the control unit 350 controls the communication unit 310 to send and receive information, causes the output unit 330 to output information input by the input unit 320 and information stored in the storage unit 360, and controls the application execution unit 340 to execute processing.

[0052] The storage unit 360 may be realized by the various storage devices described above, or an SSD, an EEPROM, a ROM, a RAM, etc. The storage unit 360 stores, for example, a pouring monitoring application 362, a program, and various other information.

[0053] <Example of provided image> Next, an example of a monitoring image provided to a user will be described with reference to the drawings. FIG. 9 is a diagram showing an example of a monitoring image IM10 provided to a user. The monitoring image IM10 shown in FIG. 9 includes, for example, a position information display area AR10, an inclination information display area AR20, a deviation amount display area AR30, a deviation direction display area AR40, and a reaction force information display area AR50 as a real-time monitoring screen. Note that the screen layout, including the displayed content, type, size, position, etc., is not limited to the example shown in FIG. 9, but the monitoring image IM10 provided in the embodiment includes at least information related to reaction force information.

[0054] The position information display area AR10 displays the position information (X, Y, and Z coordinates) of the steel pipe sheet pile 30 or the guide device 100. If there are multiple measurement points, this position information is displayed for each measurement point. The position information may be acquired, for example, by a GNSS receiver installed in the guide device 100, or by other measuring equipment or the like present at the construction site 10. The inclination information display area AR20 displays information such as the inclination of the steel pipe sheet pile 30 in the X-axis direction, the inclination in the Y-axis direction, and the inclination angle. This information is acquired by other measuring equipment or the like present at the construction site 10. The deviation amount display area AR30 displays the error (deviation) between the preset driving position (set position) of the steel pipe sheet pile 30 and the actual position for each measurement point in the X and Y directions. The deviation direction display area AR40 displays a diagram of the steel pipe sheet pile 30 from the information, and the deviation direction and deviation amount relative to the circumference of the steel pipe based on the measurement position using the circumferential movement direction and straight lines (or arrows). The reaction force information display area AR50 displays reaction force information measured by the reaction force measuring unit 120 of each guide device 100a to 100d (in the example of FIG. 9, the reaction force [kN] of each of the left and right guide rollers 110 present in each guide device 100). When warning information is to be displayed, for example, a pop-up screen showing the warning information or preliminary warning information is displayed, or the background color of the monitoring image IM10 is highlighted. Also, a warning sound corresponding to the warning information or preliminary warning information may be output.

[0055] In the embodiment, by displaying reaction force information as shown in the monitoring image IM10, it is possible to determine whether or not there is a warning sign of tilting or misalignment of the steel pipe sheet pile 30, even when no tilt or misalignment has actually occurred. For example, by providing the operator of the concrete pouring heavy equipment with reaction force information and preliminary warning information when a warning sign is detected, the operator can make corrections to reduce the reaction force (to reduce it to below the warning sign threshold) by fine-tuning the steel pipe sheet pile 30 up, down, left, or right while viewing the reaction force information. In other words, the driving operation of the steel pipe sheet pile 30 can be adjusted before tilting or misalignment occurs, thereby preventing the actual tilting or misalignment of the steel pipe sheet pile 30 from occurring. This can further improve driving accuracy. Furthermore, since the occurrence of tilting or misalignment can be reduced, the driving workload can be reduced and work efficiency can be improved.

[0056] <Processing sequence> Next, an example of processing executed by the concrete pouring monitoring system 1 in this embodiment will be described. Fig. 10 is a sequence diagram showing an example of processing executed by the concrete pouring monitoring system 1. In the following explanation, of the various processes executed by the concrete pouring monitoring system 1, a processing sequence using the guide device 100 (100a to 100d), the server device 200, and the terminal device 300 will be mainly described, and more specifically, an example in which information is provided from the server device 200 to the terminal device 300 will be described.

[0057] 10, the reaction force measuring unit 120 of the guide device 100 (100a to 100d) measures the reaction force acting on the guide rollers (a pair of opposing guide rollers) 110 (step S100). Next, the communication unit 130 of the guide device 100 transmits measurement information including the measured reaction force information to the server device 200 via the network NW (step S110).

[0058] The server device 200 acquires measurement information including reaction force information from the guide device 100 (step S120). The server device 200 may acquire measurement information from a measuring device other than the guide device 100. Next, the management unit 240 of the server device 200 stores the acquired information in the storage unit 270 (step S130). Next, the providing unit 250 of the server device 200 generates information to be provided regarding the measurement information (step S140) and transmits the generated information to the terminal device 300 (step S140).

[0059] The application execution unit 340 (or the pouring monitoring application 362) of the terminal device 300 outputs the provided information from the server device 200 and provides it to the user (step S150). This ends the processing of this sequence.

[0060] As described above, according to the embodiment, the concrete pouring monitoring system 1 includes a support member that supports the target member to be poured, a reaction force measuring unit that measures the reaction force acting on the support member, and a providing unit that provides a user with information including the reaction force information measured by the reaction force measuring unit. This allows for monitoring signs of tilt or misalignment of the target object from the reaction force information, thereby further improving concrete pouring accuracy. For example, according to the embodiment, by measuring the reaction force acting on the guide roller used to drive the steel pipe sheet pile 30 and detecting signs of tilt or misalignment of the steel pipe sheet pile in advance, concrete pouring accuracy can be improved and tilt or pile misalignment can be prevented.

[0061] According to this embodiment, not only the tilt and positional deviation of the target component to be poured but also signs of tilt that cannot be visually confirmed can be grasped in real time and quantitatively, so that detailed pouring management is possible by fine adjustment during pouring. Furthermore, according to this embodiment, the erection accuracy of the target component such as a steel pipe can be managed in real time, so the pouring accuracy of the target component can be further improved.

[0062] The above describes the form for carrying out the present invention using an embodiment, but the specific configuration is not limited to this embodiment, and also includes designs within the scope that do not deviate from the gist of the present invention.

[0063] For example, in the embodiment, the guide devices 100 installed on the target member such as a steel pipe are installed in two stages above and below the target member, but they may be installed in three or more stages. Also, in the embodiment, instead of (or in addition to) installing the guide rollers 110 so as to sandwich the joints of the steel pipe sheet pile 30, they may be installed at multiple locations so as to abut against the outer periphery of the steel pipe sheet pile 30. Also, in the embodiment, the reaction force measuring unit 120 may be installed on the guide frame 24 that abuts against the target member. By acquiring more reaction force information, signs of tilt or misalignment can be detected more accurately.

[0064] In the embodiments, at least a part of each of the components of the guide device 100, the server device 200, and the terminal device 300 may be included in other components. For example, the function of the server device 200 may be included in the terminal device 300.

[0065] The Sustainable Development Goals (SDGs) are 17 international goals adopted at the United Nations Summit in September 2015. The concrete pouring monitoring system, guide device, and concrete pouring monitoring method according to this embodiment can contribute to achieving one of the 17 SDGs, for example, goal 9, "Build resilient infrastructure, promote inclusive and sustainable industrialization, and foster innovation."
