Description

[Technical field]

[0001] The present disclosure relates to a pouring management system for cast-in-place concrete. [Background technology]

[0002] When pouring concrete, there are various control items to ensure quality from the shipment of ready mixed concrete (mixed concrete) to the completion of compaction. Conventionally, these control items were managed and recorded individually at each work site, making it difficult to share information across the entire site, including the ready mixed concrete shipping point, receiving point, pouring work site, and work management office.

[0003] In addition, construction management has often used paper media, and information is often transmitted by voice using radios, etc. For this reason, daily report management requires separate organization of the data from the paper media, and consolidating management items requires cumbersome work.

[0004] For this reason, there is a demand for a system that can easily consolidate and centrally manage concrete pouring management information.

[0005] As a related technology, for example, Patent Document 1 discloses a configuration that enables accurate confirmation at each stage of the process, from the time of ordering to the time of production, from production to transportation, and from transportation to delivery, by having a common format among the ready-mixed concrete client, the ready-mixed concrete plant, the transporter, and the ready-mixed concrete pouring site. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] JP 2014-233914 A Summary of the Invention [Problem to be solved by the invention]

[0007] However, the technology described in Patent Document 1, when viewed as a whole concrete pouring operation, merely shares information between the ready-mixed concrete plant and the pouring site, and does not centrally manage management information for all work related to pouring concrete, from shipment of ready-mixed concrete to completion of compaction.

[0008] The present disclosure aims to provide a pouring management system for in-situ concrete that can easily and reliably consolidate management information for concrete pouring. [Means for solving the problem]

[0009] A pouring management system for on-site concrete according to one aspect of an embodiment of the present invention includes a management server and a plurality of terminal devices that are arranged at each site and operated by workers, and any one of the plurality of terminal devices acquires pouring management information including information on the pot life of the concrete in each mixer truck, information on the pouring completion time, and information on the compaction time, and transmits the information to the management server. The management server links the pouring management information transmitted from the plurality of terminal devices and stores it in a database. The management server includes a compaction management unit that manages compaction work so that compaction is performed at a specific position at the concrete pouring site to satisfy a predetermined time based on information regarding the compaction time, and the compaction management unit receives a compaction start time from the terminal device when the compaction work is started at the specific position at the concrete pouring site, measures the compaction time at the position based on the compaction start time, and when the compaction time does not meet the predetermined time, changes the display mode on the compaction management screen of the terminal device to call attention to the continuation of the compaction work at the position, and when the compaction time is equal to or longer than the predetermined time, changes the display mode on the compaction management screen to prompt the end of the compaction work at the position. do.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] Hereinafter, an embodiment will be described with reference to the accompanying drawings. In order to facilitate understanding of the description, the same components in each drawing are denoted by the same reference numerals as much as possible, and duplicated description will be omitted.

[0013] 1 is an overall configuration diagram of a pouring management system 1 for pouring in-situ concrete according to an embodiment. The pouring management system 1 for pouring in-situ concrete (hereinafter also simply referred to as the "pouring management system 1") is a system that enables easy and reliable aggregation and centralized management of concrete pouring management information.

[0014] First, an overview of typical concrete pouring work will be explained with reference to Figure 2. In general, in concrete pouring work, ready mixed concrete (mixed concrete) is first produced at a ready mixed concrete plant and shipped to the pouring site, as shown in Figure 2. A mixer truck loaded with ready mixed concrete transports the ready mixed concrete to the pouring site.

[0015] Next, at the casting site, when the mixer truck carrying the ready-mixed concrete arrives, a quality test of the ready-mixed concrete is conducted. If the quality test is passed, the mixer truck moves to the location of the pump truck, and the ready-mixed concrete loaded on the mixer truck is pumped by the pump truck and poured into the formwork. The pouring work is managed so that it falls within the potable time of the ready-mixed concrete in the mixer truck. Here, the "potable time" of concrete is the time during which pouring work can be performed after the ready-mixed concrete is produced, for example, the time until the viscosity or condition of the ready-mixed concrete becomes unsuitable for use. In the example in Figure 2, the "potable time" of concrete is the period from the start of mixing at the ready-mixed concrete plant to the completion of pouring. The potable time varies depending on various conditions such as the season, but is generally about 90 to 120 minutes.

[0016] Next, the fresh concrete in the formwork that has been poured is compacted. In compaction, workers use a vibrator or similar device to input vibrations into the fresh concrete. This removes air bubbles trapped in the concrete and increases its density. To achieve the desired compaction effect, compaction should be performed at intervals of approximately 50 cm or less, with the compaction time at each position being approximately 5 to 15 seconds.

[0017] In this embodiment, "casting" is defined as "the action up to the time when concrete is poured into the formwork" and "compaction" is defined as "the action of applying vibration with a vibrator after pouring into the formwork", and casting work and compaction work are distinguished as separate works. For this reason, in the example of FIG. 2, the time when the casting work is completed (hereinafter also referred to as "casting completion time"), which is written as "*casting completion" in the figure, and the "compaction start time" are set to be the same. By managing the casting work and the compaction work separately in this way, it is possible to manage the casting work and the compaction work separately, and more accurate work management is possible. Note that the "compaction start time" may be earlier than the "casting completion time" and the casting work and the compaction work may overlap, that is, the compaction work may be started just before the casting work is completed.

[0018] When pouring and compaction are completed over the entire area of ​​a specified layer (the "first layer" in Fig. 2), work moves on to the next higher layer (the "second layer" in Fig. 2). Driving and compaction are similarly performed over the entire area of ​​the next layer. The interval between the time when compaction is completed at a specified position on a specified layer and the time when compaction is completed at the position directly above that specified position on the next higher layer is managed as the pouring time interval. The pouring time interval varies depending on various conditions such as the season, but is generally about 120 to 150 minutes. In this way, pouring and compaction are repeated for each of several layers of a specified height, and the construction object is finally completed.

[0019] Returning to FIG. 1, the concrete pouring management system 1 includes a management server 2, a plurality of terminal devices 3, 4, and 5, and a wireless device 6.

[0020] The management server 2 is a device that consolidates and centrally manages concrete pouring management information (pouring management information). The management server 2 can provide the consolidated pouring management information to all terminals in the system, including the multiple terminal devices 3, 4, and 5, and thus the pouring management information can be shared within the system.

[0021] The multiple terminal devices 3, 4, and 5 are arranged at each work site and operated by workers P1, P2, and P3. For example, tablets having a touch panel can be used as the terminal devices 3, 4, and 5. In the following description, the terminal devices 3, 4, and 5 may also be referred to as "tablets 3, 4, and 5."

[0022] 1, a configuration including three terminal devices 3, 4, and 5 is exemplified as the multiple terminal devices. Terminal device 3 is placed in a ready-mixed concrete plant, and is used by worker P1 at the ready-mixed concrete plant to manage concrete shipment. Terminal device 4 is placed near the delivery entrance at the pouring site, and is used by worker P2 near the delivery entrance to manage concrete delivery and pouring. Terminal device 5 is placed near the formwork into which concrete is poured at the pouring site, and is used by worker P3 near the formwork to manage concrete compaction.

[0023] The wireless device 6 is a communication device for performing wireless communication between the management server 2 and the terminal devices 3, 4, and 5. The management server 2 and the terminal devices 3, 4, and 5 can transmit and receive information to and from each other via the wireless device 6 through a communication network such as the Internet or an intranet.

[0024] In the concrete pouring management system 1, any one of the multiple terminal devices 3, 4, 5 acquires pouring management information including information on the potable time of the concrete in each mixer truck, information on the pouring completion time, and information on the compaction time, and transmits it to the management server 2. In the example of FIG. 1, the terminal device 3 acquires information such as the concrete shipping time from the ready-mixed concrete plant, the loading amount, the mixer truck ID, and the concrete mix ratio (information on the potable time) through the input operation of the worker P1, and transmits it to the management server 2. Also, the terminal device 4 acquires information such as the pouring completion time and the mixer truck ID through the input operation of the worker P2, and transmits it to the management server 2. Furthermore, the terminal device 5 acquires information such as the compaction start time, the compaction completion time, and the cell ID (information on the compaction time) through the input operation of the worker P3, and transmits it to the management server 2.

[0025] The management server 2 links the concrete pouring management information transmitted from the multiple terminal devices 3, 4, and 5 and stores it in a database. The concrete pouring management information stored in the database can be viewed from other terminals in the system, such as the terminal devices 3, 4, and 5, and thus the concrete pouring management information can be shared among the terminals in the system.

[0026] The concrete pouring management system 1 can also include a PC7 (hereinafter referred to as "office PC7") that is installed in a place other than the concrete pouring site (for example, the office of a company that carries out concrete pouring work). An office staff member P4 can access the management server 2 using the office PC7 and check the concrete pouring management information in real time.

[0027] The arrangement of the multiple terminal devices 3, 4, and 5 is not limited to the example in Fig. 1. For example, the ready-mix concrete plant may be configured such that neither the worker P1 nor the terminal device 3 is arranged. In this case, the information related to the pot life of the concrete can be input by the worker P2 using the terminal device 4, for example, when the concrete is delivered to the pouring site.

[0028] Fig. 3 is a functional block diagram of the management server 2. Regarding the above-mentioned functions, the management server 2 includes a construction information database 21, a construction information processing unit 22, a potable time management unit 23, a compaction management unit 24, and a model display unit 25, as shown in Fig. 3.

[0029] The construction information database 21 stores pouring management information transmitted from each tablet 3, 4, 5 (terminal device 3, 4, 5) and associated and compiled by the construction information processing unit 22.

[0030] The construction information processing unit 22 associates various pieces of information related to pouring management information transmitted from each tablet 3, 4, 5 to create an information set. The construction information processing unit 22 creates a set of pouring management information for each work unit block of the construction object, for example. The construction information processing unit 22 transmits the created set of pouring management information to the construction information database 21.

[0031] The potable time management unit 23 manages the potable time of the concrete based on various information related to the pouring management information transmitted from each tablet 3, 4, 5. Based on the information related to the potable time among the pouring management information, the potable time management unit 23 manages the pouring work so that pouring of the concrete into the pouring site is completed within the allowable range of the potable time.

[0032] The compaction management unit 24 manages compaction at the concrete pouring site based on various information related to the concrete pouring management information transmitted from each tablet 3, 4, 5. The compaction management unit 24 manages compaction work so that compaction is performed at a specific position at the concrete pouring site for a predetermined time based on information related to compaction time included in the concrete pouring management information.

[0033] The model display unit 25 adds the construction status to a model of the construction object based on various information related to pouring management information transmitted from each tablet 3, 4, 5 and displays it.

[0034] The flow of processes performed by the pouring management system 1 of this embodiment during concrete pouring work is, for example, as follows.

[0035] Process 1: The mixer truck departs from the ready-mix concrete plant. Tablet 3 sends information such as the mixer truck ID (identification information for the mixer truck), shipping time, loading amount, and concrete mix to management server 2 (there may be cases where worker P1 and tablet 3 are not stationed at the ready-mix concrete plant).

[0036] Process 2: The mixer truck arrives at the pouring site. (If Tablet 3 is not available, information such as "mixer truck ID," "shipping time," "load," and "concrete mix" is sent from Tablet 4 to Management Server 2. For example, worker P2 receives a slip from the mixer truck driver and enters the information on the slip into Tablet 4.)

[0037] Process 3: The potable time management unit 23 of the management server 2 calculates the "potable time" from the "mixer truck ID" and "shipping time" received in process 1 or process 2. The potable time management unit 23 of the management server 2 transmits information on the "potable time" to the tablet 4.

[0038] Process 4: Pouring work is carried out. Based on the received "potable time," tablet 4 displays a warning when the potable time approaches the allowable time. Each time the pouring of concrete in an individual mixer truck is completed, information on the "mixer truck ID" and "pouring completion time" is sent from tablet 4 to management server 2.

[0039] Step 5: The construction information processing unit 22 of the management server 2 identifies the cell (work unit block) where the concrete was poured, based on the "concrete mixer ID" and "pouring completion time" received in step 4, and the "load" received in step 1 or step 2. The construction information processing unit 22 links the "cell ID (identification information of the identified work unit block)" with the "concrete mixer ID," "shipping time," and "pouring completion time," and stores them in the construction information database 21.

[0040] Process 6: Compaction work is carried out. Each time compaction is completed for each cell, the "cell ID," "compaction start time," and "compaction completion time" are sent from the tablet 5 to the management server 2.

[0041] Step 7: The compaction management unit 24 of the management server 2 calculates the “compaction time” for each cell based on the “cell ID,” “compaction start time,” and “compaction completion time” received in step 6.

[0042] Step 8: The construction information processing unit 22 of the management server 2 further links the “compaction time” calculated in step 7 to the data set of step 5 and stores it in the construction information database 21.

[0043] Step 9: When the management server 2 receives designation information for a specific cell from its own machine or another terminal, it outputs pouring management information such as the "mixer truck ID," "shipping time," "pouring completion time," "compaction time," "pouring time interval," and "concrete mix" for that cell from the construction information database 21 based on the "cell ID" of that cell, and provides it to the requester. (The display mode is, for example, to display a mesh of a three-dimensional model of the construction object, and when a specific cell is clicked on the display screen, to obtain and display the pouring management information linked to that cell from the construction information database 21.)

[0044] Fig. 4 is a hardware configuration diagram of the management server 2 and the terminal devices 3, 4, and 5. As shown in Fig. 4, the management server 2 and the terminal device 3 can be physically configured as a computer system including a CPU (Central Processing Unit) 101, a RAM (Random Access Memory) 102 and a ROM (Read Only Memory) 103 which are main storage devices, an input device 104 such as a keyboard and a mouse which are input devices, an output device 105 such as a display, a communication module 106 which is a data transmission / reception device such as a network card, an auxiliary storage device 107, and the like.

[0045] The functions of the management server 2 shown in Fig. 3 and the functions of the terminal devices 3, 4, and 5 described above are realized by loading a predetermined computer software (concrete pouring management program) onto hardware such as the CPU 101 and RAM 102, operating the communication module 106, the input device 104, and the output device 105 under the control of the CPU 101, and reading and writing data in the RAM 102 and the auxiliary storage device 107. That is, by executing the concrete pouring management program according to this embodiment on a computer, the management server 2 functions as the construction information database 21, the construction information processing unit 22, the potable time management unit 23, the compaction management unit 24, and the model display unit 25 in Fig. 3.

[0046] The pouring management program of this embodiment is stored, for example, in a storage device provided in a computer. The pouring management program may be configured so that a part or all of it is transmitted via a transmission medium such as a communication line, and is received and recorded (including installed) by a communication module or the like provided in the computer. The pouring management program may be configured so that a part or all of it is recorded (including installed) in the computer from a state in which it is stored in a portable storage medium such as a CD-ROM, DVD-ROM, or flash memory.

[0047] The management server 2 and the terminal devices 3, 4, and 5 may be circuits configured with analog circuits, digital circuits, or analog-digital mixed circuits. They may also be equipped with control circuits that control the functions of the management server 2 and the terminal devices 3, 4, and 5. Each circuit may be implemented using an ASIC (Application Specific Integrated Circuit), an FPGA (Field Programmable Gate Array), or the like.

[0048] An example of a management screen used for managing concrete pouring work in the concrete pouring management system 1 will be described with reference to Figs. 5 to 10. Fig. 5 is a diagram showing an example of a progress status screen 11 of the management server 2. The progress status screen 11 shown in Fig. 5 is created by the model display unit 25 based on concrete pouring management information aggregated by the construction information processing unit 22, for example. This progress status screen 11 is provided to various places by being displayed on the display device of the management server 2 or on the display of the office PC 7, for example.

[0049] As shown in Fig. 5, a three-dimensional model 12 of a construction object (a bridge pier in this embodiment) is displayed on the progress status screen 11. This three-dimensional model 12 is divided into task unit blocks (sometimes also written as "cells") to which pouring management information is associated and stored. A task unit block is treated as one unit of a concrete pouring work.

[0050] It is preferable that the work unit blocks are divided according to the range (range of influence of compaction) to which vibrations can be transmitted from a vibration generating device such as a vibrator placed at any one point in the concrete during compaction work. For example, the three-dimensional model 12 is divided into a number of layers at predetermined heights (e.g., 50 cm suitable for compaction), and each layer is further divided into work unit blocks of 50 cm square.

[0051] In the progress status screen 11, the display mode is changed according to the progress of the concrete pouring work for each work unit block of the three-dimensional model 12, and the concrete pouring progress is reflected in real time. For example, in the example of Fig. 5, blocks where concrete pouring has been completed are painted gray, blocks where concrete pouring is currently in progress are painted white, and blocks where concrete pouring has not yet started are displayed in wireframe. By using the progress status screen 11 as shown in Fig. 5, the progress of the construction can be grasped from a bird's-eye view even at a location away from the site, such as whether the concrete pouring work currently being carried out is being carried out according to the construction plan without any strain or waste, whether there is any imbalance in the concrete pouring speed of each concrete pouring team, etc.

[0052] The management server 2 can manage the progress of concrete pouring work and concrete pouring management information for each of a plurality of cells (task unit blocks) obtained by meshing the construction object.

[0053] Fig. 6 is a diagram showing an example of a concrete potable time management screen 13. The potable time management screen 13 shown in Fig. 6 is displayed on a tablet 4 arranged at the delivery entrance of the concrete pouring site, for example, and used by a worker P2.

[0054] The right half of the potable time management screen 13 displays an input table for the departure time 13B and completion time 13C for each mixer truck being transported from the ready-mixed concrete plant to the pouring site. The departure time 13B is, for example, information on the time when the mixer truck departs from the ready-mixed concrete plant, and is input by the worker P1 from the tablet 3 at the ready-mixed concrete plant. If the tablet 3 is not provided at the ready-mixed concrete plant, the worker P2 may input the information using the tablet 4. In this case, the worker P2 can input information such as the departure time by referring to the information written on the slip received from the driver of the mixer truck. The departure time 13B corresponds to the "shipping time" in the above-mentioned pouring management information. The completion time 13C is information on the time when all the concrete in the mixer truck is discharged and used for pouring, and is input by the worker P2 from the tablet 4 at the delivery entrance. The completion time 13C corresponds to the "pouring completion time" in the above-mentioned pouring management information.

[0055] The right half of the potable time management screen 13 displays potable time information 13A for each mixer truck being transported from the ready-mixed concrete plant to the pouring site. The potable time information 13A displays the departure time and the remaining potable time for each truck. In the example of FIG. 6, for example, the departure time of the sixth mixer truck is 4 p.m., and 26 minutes are displayed as remaining potable time. For the fourth mixer truck, the departure time is 12 p.m., and pouring has been completed, so the potable time is displayed as "Complete." For the fifth mixer truck, the departure time is 3 p.m., and the current time has already exceeded the allowable range of the specified potable time, so the potable time is displayed as "Exceeded."

[0056] The potable time information is provided to the tablet 4 from the potable time management unit 23 of the management server 2. The potable time management unit 23 calculates the allowable time of the potable time of each mixer truck based on the "departure time" information inputted to the tablet 3 (or tablet 4), the "completion time" information inputted to the tablet 4, and the ID information (mixer truck ID) of the mixer truck related to these pieces of information, and transmits information on this allowable time or information on the remaining time until the allowable time to the tablet 4, and causes it to be displayed on the potable time management screen 13 of the tablet 4.

[0057] In addition, the usable time management unit 23 can change the display mode on the usable time information 13A screen for a mixer truck that has been shipped a long time ago and has not yet completed pouring by adding a frame to the area of ​​the corresponding mixer truck or by changing the color, thereby visually issuing a warning to worker P2 and urging him to quickly complete pouring of the corresponding mixer truck before the usable time expires.

[0058] 7 is a diagram for explaining a method of linking the mixer truck ID for each task unit block. The linking illustrated in FIG. 7 is performed by the construction information processing unit 22 of the management server 2, for example.

[0059] As described above, the management server 2 divides the construction object into multiple layers, and divides each layer into multiple work unit blocks to manage pouring management information for each block. In the example of Fig. 7, the three-dimensional model 12 of the construction object is divided into three lots in the vertical direction as shown in the upper left of the figure, with the lower lot being divided into two layers, the middle two lots being divided into four layers, and the upper three lots being divided into six layers. Here, the linking procedure for the second layer of one lot is illustrated.

[0060] The second layer of one lot is divided into 42 blocks of 7 columns and 6 rows, as shown in the upper right of Fig. 7. In these block divisions, the concrete pouring order is assigned in a zigzag pattern from the first block in the upper left to the 42nd block in the lower left, as shown in the lower right of Fig. 7. This concrete pouring order information is provided to, for example, tablet 4 and tablet 5, and worker P2 and worker P3 perform concrete pouring work based on this information.

[0061] Since the management server 2 can obtain information on the volume of each block and the amount of concrete loaded by each mixer truck, by comparing this information, it can calculate which mixer truck's concrete was used for which range of blocks in which pouring order. For example, in the example of Figure 7, as shown in the lower left of the figure, it is calculated that the concrete from the Nth mixer truck was used for the 1st to 16th blocks, the concrete from the N+1th mixer truck was used for the 17th to 32nd blocks, and the concrete from the N+2th mixer truck was used for the 33rd to 42nd blocks.

[0062] The construction information processing unit 22 calculates the relationship between the work unit block thus calculated and the mixer truck ID. Based on the relationship, for each work unit block, the mixer truck ID of the mixer truck that transported the ready mixed concrete used in pouring this block can be assigned.

[0063] Fig. 8 is a diagram showing an example of the compaction management screen 14. The compaction management screen 14 in Fig. 8 is displayed on a tablet 5 arranged, for example, near a formwork at a concrete pouring site, and is used by a worker P3.

[0064] The compaction management screen 14 displays the progress of the compaction work for each work unit block in the layer currently being worked on (the third layer in the figure). A number is assigned to each work unit block in the compaction management screen 14, and in the example of Figure 8, F, G, H, and I are assigned to each row, and 3, 4, and 5 are assigned to each column.

[0065] For example, when a worker performing compaction (compaction worker) installs a vibrator in a certain block and starts compaction work, worker P3 touches the area of ​​the corresponding block on the compaction management screen 14 of the tablet 5, and the compaction start time and identification information (cell ID) of the corresponding block are transmitted to the management server 2. In response to receiving the compaction start time, the compaction management unit 24 of the management server 2 starts managing the compaction time of the corresponding block.

[0066] For example, when the compaction time does not reach a predetermined time, the compaction management unit 24 changes the display mode on the compaction management screen 14 to call attention to the need to continue compaction work on the block in question, such as by changing the color of the block to yellow, such as block "G5" in Figure 8, or by displaying "NG" (meaning that work should continue as there is still insufficient compaction time) on the block along with the elapsed time.

[0067] On the other hand, when the compaction time reaches or exceeds a predetermined time, the display manner on the compaction management screen 14 is changed to prompt the completion of the compaction work on the relevant block, for example, by changing the color of the block to blue, as in the case of block "G4" in Figure 8, or by displaying "OK" on the block along with the elapsed time (meaning that the compaction time has been sufficient and it is OK to end the work).

[0068] Then, when the compaction worker who performs compaction finishes the compaction work in the corresponding block, the worker P3 touches the area of ​​the corresponding block on the compaction management screen 14 of the tablet 5 again, and the compaction end time and the cell ID of the corresponding block are transmitted to the management server 2. In response to receiving the compaction end time, the compaction management unit 24 of the management server 2 ends the management of the compaction time of the corresponding block, and changes the display mode on the compaction management screen 14 so that it is clear that the compaction work in the corresponding block has been completed, for example, by changing the color of the block to gray, as in the blocks "F3", "F4", "F5", and "G3" in FIG. 8. In this way, by using the compaction management screen 14 as shown in FIG. 8, the compaction worker can visually and intuitively grasp information such as whether the compaction time is insufficient or whether there are any uncompacted areas remaining during the work.

[0069] Furthermore, the compaction management unit 24 of the management server 2 can calculate the allowable time for the overlay time based on the compaction completion time of each block in the layer below, and can manage the compaction work based on the overlay time. For example, like the blocks "I3", "I4", and "I5" in Fig. 8, the display mode on the compaction management screen 14 can be changed so that a warning is displayed to promptly complete the compaction work for blocks that are approaching the allowable time for the overlay time, such as by flashing the color of the block.

[0070] FIG. 9 is a diagram showing an example of the pouring speed management screen 15. The management server 2 can display a graph of the concrete pouring speed at the pump nozzle, which is the total concrete pouring amount over time, on the pouring speed management screen 15. The graph in FIG. 9 shows the concrete pouring completion time on the horizontal axis and the concrete pouring amount (m 3 9. The pouring completion time on the horizontal axis of Fig. 9 indicates the elapsed time from the start of pouring work, and the pouring quantity on the vertical axis indicates the cumulative amount of ready mixed concrete poured into the pouring site at each time from the start of work. The total pouring quantity can be calculated, for example, by the construction information processing unit 22 using information on mixer trucks that have completed pouring and information on the load of each of the corresponding mixer trucks from the pouring management information.

[0071] By using the pouring speed management screen 15 as shown in Figure 9 to compare the planned delivery speed with the actual pouring speed, the speed balance between the supply side and the pouring side of the ready-mix concrete can be adjusted. This makes it possible to suppress the interruption of pouring due to a shortage of concrete supply and the reduction in usable time due to the increase in the number of agitator trucks waiting due to an oversupply, enabling smooth continuous pouring. In addition, since the pouring speed, which changes from moment to moment, can be grasped in real time, it becomes possible to flexibly respond to unexpected problems that may occur during construction, such as how much time is left.

[0072] Fig. 10 is a diagram showing an example of the construction information display screen 16. The construction information display screen 16 in Fig. 10 is an example of a user interface for easily viewing and acquiring pouring management information for each task unit block stored in the construction information database 21. The construction information display screen 16 is displayed on the display device of the management server 2 or on another terminal device such as the office PC 7.

[0073] As shown in FIG. 10, the construction information display screen 16 displays a three-dimensional model 12 of the construction object similar to the progress status screen 11 of FIG. 5. This three-dimensional model 12 is divided into each of the above-mentioned task unit blocks. Then, by inputting a predetermined operation such as double-clicking on a specific block on the screen, a window 16A containing pouring management information for the block is popped up. This process is realized, for example, by the model display unit 25 referring to the construction information database 21 based on the cell ID assigned to the selected task unit block, acquiring various information associated with the cell ID, and creating the window 16A using the acquired information and displaying it on the construction information display screen 16.

[0074] The information displayed in the window 16A includes, for example, as shown in FIG. 10, "1. Pouring order of each layer (mesh number)", "2. Plane coordinates of mesh", "3. Volume of one mesh", "4. Mixer truck number and shipping time", "5. Time to complete pouring", "6. Start time of compaction", "7. Time to complete compaction", "8. Time interval between pours (second layer and after)", "9. Results of concrete quality test", "10. Date of pouring", "11. Other (name of ready-mixed concrete plant, etc.)". The "concrete quality test results" include information such as the slump, air volume, temperature, and outside air temperature of the concrete, and are conducted once every 20 to 150 m3 depending on the conditions of the structure. Generally, all mixer trucks are not tested, but in special construction, all tests may be conducted.

[0075] The method of outputting the pouring management information stored in the construction information database 21 is not limited to displaying it in conjunction with the three-dimensional model 12 as in the construction information display screen 16 of Fig. 10. For example, it can also be output as a list in CSV format.

[0076] The pouring management system 1 for on-site pouring concrete according to this embodiment includes a management server 2 and multiple terminal devices 3, 4, and 5 that are arranged at each site and operated by workers P1, P2, and P3. Any of the multiple terminal devices 3, 4, and 5 acquires pouring management information including information on the potable time of the concrete in each mixer truck, information on the pouring completion time, and information on the compaction time, and transmits it to the management server 2. The management server 2 associates the pouring management information transmitted from the multiple terminal devices 3, 4, and 5 and stores it in the construction information database 21.

[0077] With this configuration, various information related to pouring management information input individually using the multiple terminal devices 3, 4, and 5 is collected in the management server 2, and each piece of information is associated with the others and then stored together in the construction information database 21. This allows the pouring management information to be collected without relying on paper media or verbal communication between workers at the pouring site, eliminating information omissions and misunderstandings due to human error during transmission, and allowing the management information of concrete pouring to be collected more reliably. In addition, since the complicated work that workers had to perform to collect information such as data organization on paper media as in the past is no longer necessary, the management work can be saved and the management information of concrete pouring can be collected more easily. As a result, the pouring management system 1 of this embodiment can collect the management information of concrete pouring simply and reliably. In addition, by referring to the pouring management information stored in the construction information database 21 from the management server 2 or the office PC 7, the construction manager can grasp the progress of the pouring work in real time, improving construction management.

[0078] In addition, in the pouring management system 1 of this embodiment, the management server 2 divides the construction object to be poured concrete at a predetermined height into multiple layers, divides each layer into predetermined areas to set multiple work unit blocks, and links the pouring management information transmitted from multiple terminal devices 3, 4, and 5 for each work unit block and stores it in the construction information database 21.

[0079] This configuration makes it possible to refer to the pouring management information for each task unit block, and by using this pouring management information, it becomes possible to manage the compaction work and the pouring work for each task unit block, so that detailed work management can be performed for each process of concrete pouring work. In addition, after the pouring work is completed, the construction information database 21 accumulates pouring management information for all task unit blocks of the construction object, so by using this information, it is possible to provide information related to concrete for each task unit block. Information related to concrete includes, for example, information on materials such as the mix of concrete used and the manufacturing date, and information on production such as whether pouring was completed within the usable time, whether compaction was performed to satisfy the specified time, and whether pouring was completed within the specified time. In other words, it is possible to ensure the traceability of the quality of the concrete structure, which is the construction object, after the construction is completed.

[0080] In the concrete pouring management system 1 of this embodiment, the management server 2 has a three-dimensional model 12 in which the construction object is divided into task unit blocks, and the three-dimensional model 12 can be displayed on a display device, for example, as in the construction information display screen 16 illustrated in Fig. 10. When a specific task unit block is specified on the construction information display screen 16 of the display device, for example, by double-clicking, the management server 2 refers to the construction information database 21 and outputs the concrete pouring management information linked to the specified task unit block.

[0081] This configuration allows the system user to specify the work unit block for which he / she wants to check the pouring management information on the 3D model 12, making it possible to obtain the desired information with extremely simple and intuitive operations, improving the usability of the pouring management information accumulated by the system. In addition, since the pouring management information is handled as electronic data, the information can be enjoyed even in remote locations, enabling a wider range of pouring management information to be utilized.

[0082] Furthermore, in the concrete pouring management system 1 of this embodiment, the potable time management unit 23 manages pouring work so that pouring of concrete to the pouring site is completed within the allowable range of potable time, based on information related to potable time among the pouring management information aggregated in the management server 2. Similarly, the compaction management unit 24 manages compaction work so that compaction is performed for a predetermined time or more at a specific position of the pouring site, based on information related to compaction time among the pouring management information aggregated in the management server 2.

[0083] Conventionally, quality control of concrete has been carried out in a customary manner, and for example, control of compaction time and the like was vague, which sometimes led to construction defects (disposal of fresh concrete due to exceeding pot life, material separation due to over- or under-compaction, occurrence of cold joints, etc.). In contrast, in this embodiment, the above-mentioned configuration makes it possible to meticulously control pouring and compaction work by using pouring control information aggregated in the management server 2, and construction defects can be prevented by quantitatively controlling quality items, which results in improved quality of the generated concrete structure.

[0084] The present embodiment has been described above with reference to specific examples. However, the present disclosure is not limited to these specific examples. Any design modifications made by a person skilled in the art to these specific examples are also included within the scope of the present disclosure as long as they have the features of the present disclosure. The elements of each of the above-mentioned specific examples and their arrangements, conditions, shapes, etc. are not limited to those exemplified and can be changed as appropriate. The combination of each of the elements of each of the above-mentioned specific examples can be changed as appropriate as long as no technical contradiction occurs.

[0085] In the above embodiment, the terminal device 5 acquires information (information related to compaction time) such as the compaction start time, compaction completion time, and cell ID by the input operation of the worker P3 and transmits it to the management server 2. However, the method of acquiring information related to compaction time may be a method other than the input operation of the worker. For example, the method may be a method of capturing an image of the work area of ​​the compaction work including the compaction worker by an imaging unit (still image camera, video camera, etc.), estimating a skeletal model of the compaction worker using the captured image, and estimating the work position of the compaction work of the compaction worker based on the estimated skeletal model. In this method, an inference device such as a deep neural network that acquires the correspondence between a person image and a skeleton by a machine learning method such as deep learning can be used to estimate the skeletal model. In this method, for example, the position of the feet of the compaction worker can be estimated as the work position based on the skeletal model. In addition, in the case of this method, the compaction time in a predetermined work unit block can be measured based on the information of the estimated work position of the compaction worker. These functions may be provided in the terminal device 5 or in the management server 2.

[0086] In the above embodiment, the compaction management screen 14 (see FIG. 8) displayed on the terminal device 5 arranged near the formwork at the casting site is used to present the compaction worker with the progress of the compaction work for each work unit block. In addition, a teaching device may be provided to teach the compaction worker the work order for each work unit block. The teaching device is, for example, installed around the work area (formwork) of the compaction work and has signs (for example, gauges with numbers or letters corresponding to each work unit block) that display the individual positions of multiple work unit blocks in the work area, and a terminal device that can be referred to by the compaction worker. In this configuration, the work order is presented on the terminal device using information corresponding to the signs, so that the compaction worker can be taught the work order for each work unit block. The teaching device may also be configured to have a display device (for example, a head-mounted display) for AR (augmented reality). In this configuration, when the compaction worker looks at the work area through the display device, the work unit blocks are superimposed on the work area on the display device, so that the compaction worker can be taught the work order. The teaching device may also be configured to have a lighting device that irradiates light at any position in the work area. In this configuration, the lighting device can be used to irradiate light at positions on the work area that correspond to one or more work unit blocks, so that the compaction worker can be taught the work order.
