Description

[Technical field]

[0001] The present invention relates to a concrete pouring management system and a concrete pouring management method. [Background technology]

[0002] When constructing a vertical shaft underground, a method of directly inserting a hose from a pump vehicle placed on the ground into the shaft to pour concrete into the shaft is sometimes used. However, if a bracing support is installed in the shaft, even if the hose is moved significantly laterally while still inserted according to the progress of concrete pouring, it may not be possible to immediately move it to the desired position due to interference with the support. For this reason, a pipe is laid horizontally in advance above the pouring area in the shaft, and concrete is often pumped using this horizontal pipe. The horizontal pipe has multiple discharge ports corresponding to the entire pouring area, and concrete pumped from the pump vehicle to the inlet of the pipe can be discharged to the entire pouring area via the discharge ports. Patent Document 1 discloses an automatic concrete pouring method characterized in that "a concrete supply pipe is erected above the area to be poured so as to cover the area, concrete is discharged from multiple discharge ports formed in the concrete supply pipe, and the amount of concrete discharged from the discharge ports is controlled by detecting whether the height of the concrete at each discharge port is at a predetermined value, thereby making the height of the concrete uniform."

[0003] [Patent Document 1] Japanese Patent Application Publication No. 5-25938 Summary of the Invention [Problem to be solved by the invention]

[0004] The concrete pipe is equipped with multiple valves corresponding to each of the discharge ports, and the timing of concrete discharge can be adjusted for each valve. Therefore, during concrete pouring work, there is a period of time when concrete stagnates inside the pipes that are not being poured, and there is a risk of the pipes becoming clogged after a certain period of time has passed. Conventionally, the stagnation time of concrete inside the pipes was managed manually. For this reason, problems such as pipe blockages occurred due to human error or poor communication and coordination between workers. From this perspective, the present invention aims to propose a concrete pouring management system and a concrete pouring management method that prevent clogging of concrete pipes having multiple discharge outlets. [Means for solving the problem]

[0005] In order to solve the above problems, the present invention provides a concrete pouring management system that includes a measuring device that measures the closed time of multiple valves corresponding to each of multiple outlets of a concrete pipe, and a control device that performs at least one of the following: issuing a warning when the measured closed time has exceeded a predetermined time, and opening the valve when the predetermined time has passed. The present invention also relates to a concrete pouring management method, which includes a step in which a measuring device measures the closed times of a plurality of valves corresponding to each of a plurality of outlets of a concrete pipe, and a step in which a control device executes at least one of the following steps: issuing a warning when the measured closed time has exceeded a predetermined time, and opening the valve after the predetermined time has elapsed. According to this configuration, the measuring device can manage the retention time of concrete in the piping section corresponding to each valve. Furthermore, the control device can notify the piping section that may be clogged based on the valve closing time. A worker who notices the notification can open the corresponding valve. Furthermore, if the valve is equipped with a specified actuator and can be opened and closed automatically, the control device can control the actuator to open the valve corresponding to the piping section that may be clogged. In this way, according to the present invention, it is possible to prevent clogging of a concrete pipe having multiple discharge ports. Furthermore, it is not necessary to manage the valve closing time, and the number of personnel required for pouring concrete can be reduced.

[0006] Moreover, it is preferable that the measuring device resets the closing time of the valve (the valve that has been opened) corresponding to the refreshed piping portion. According to this configuration, the stagnation time of concrete in the refreshed piping section becomes zero, so that the stagnation time of concrete can be appropriately managed even when the valve is opened and closed multiple times.

[0007] It is also preferable that the valve is a gate valve, and the measurement device comprises a reflecting portion that is displaced in response to opening and closing of the gate valve, and a photoelectric sensor that receives light irradiated onto the reflecting portion. According to this configuration, the mechanism for determining whether the valve is open or closed can be realized with a simple configuration.

[0008] In addition, it is preferable that the control device is provided with a display unit that displays concrete pouring plan information, concrete pouring implementation information, and difference information between the plan information and the implementation information for each layer of the concrete pouring. With this configuration, the progress of concrete pouring can be easily checked.

[0009] The control device preferably includes a form unit that outputs a form on which at least the implementation information is entered. With this configuration, records of concrete pouring can be easily managed. Effect of the Invention

[0010] According to the present invention, clogging of a concrete pipe having a plurality of discharge ports can be prevented. [Brief description of the drawings]

[0012] Hereinafter, the embodiment of the present invention will be described in detail with reference to the drawings. Each drawing is merely a schematic illustration to allow a sufficient understanding of the present invention. Therefore, the present invention is not limited to the illustrated examples. In each drawing, common or similar components are denoted by the same reference numerals, and duplicated explanations thereof will be omitted.

[0013] [composition] FIG. 1 is a functional configuration diagram of a concrete pouring management system of this embodiment. The concrete pouring management system 100 is a system that manages pouring of concrete into a pouring area in a shaft. The concrete pouring management system 100 includes a tablet terminal 1 and a control device 2. The tablet terminal 1 and the control device 2 each include hardware such as an input unit, an output unit, a control unit, and a storage unit. For example, when the control unit is configured with a CPU (Central Processing Unit), information processing by a computer including the control unit is realized by program execution processing by the CPU. In addition, the storage unit included in the computer stores various programs for realizing the functions of the computer according to instructions from the CPU. This realizes collaboration between software and hardware. The program can be provided by recording it on a recording medium or via a network. The output unit may include the function of a display unit that displays a screen.

[0014] The piping 3 is used for pouring the concrete in the shaft. The piping 3 is a horizontal concrete piping installed above the concrete pouring area. The piping 3 is equipped with a supply port 31, a plurality of valves 32, and a plurality of discharge ports 33. Supply port 31 is a connection between piping 3 and a pipe (not shown) extending from a pressure pump (not shown) of a pump vehicle or the like, and guides concrete supplied from the pressure pump (white arrow in FIG. 1) to piping 3. The valve 32 includes a T-shaped pipe capable of branching concrete downward. The valve 32 switches between a state in which the concrete in the pipe 3 flows downward (open state) and a state in which the concrete does not flow downward (closed state), and is disposed at intervals corresponding to partial areas of the casting area. The valve 32 is preferably, for example, a gate valve, and is a gate valve in this embodiment, but is not limited thereto. The discharge port 33 is a cylindrical body attached to the lower part of the valve 32. The concrete branched at the valve 32 is discharged from the discharge port 33 to a partial area located below the valve 32.

[0015] The tablet terminal 1 is an information processing device carried by a worker M at a work site where concrete is poured. For example, the tablet terminal 1 can input the start time and end time of pouring for each valve 32 according to input from the worker M, and record the pouring time for each valve 32. The control device 2 is an information processing device used by a manager who manages the progress of concrete pouring. The control device 2 is preferably, but not limited to, a notebook computer. The control device 2 includes a warning unit 21, an opening / closing unit 22, a display unit 23, and a form unit 24. The control device 2 also stores plan information 25, implementation information 26, and difference information 27.

[0016] (Details of control device 2) The warning unit 21 warns that the closing time of the valve 32 has elapsed for a predetermined time. During concrete pouring, the first valve 32, which was open to discharge concrete from the first discharge port 33, is closed, the second valve 32 is opened, and concrete is discharged from the second discharge port 33. In this case, concrete stagnates inside the first valve 32 and the piping 3 around it, and there is a risk that the piping 3 will be clogged after a predetermined time has elapsed. The warning unit 21 can warn of a piping portion that may be clogged based on the closing time of the valve 32. The worker M who notices the warning can open the first valve 32. The closing time of the valve 32 is the time during which the valve 32 is in a closed state. A method for measuring the closing time of the valve 32 will be described later. In addition, the warning by the warning unit 21 may be, for example, a visual warning from a lamp or tablet terminal 1 arranged at the site, or an auditory warning from a speaker or tablet terminal 1 arranged at the site, but is not limited thereto.

[0017] When the valve 32 includes a predetermined actuator (not shown) and can automatically open and close the valve 32, the opening / closing unit 22 opens the valve 32 when the closing time of the valve 32 has exceeded a predetermined time. The opening / closing unit 22 can control the actuator to open the valve 32 corresponding to the piping portion that may be clogged. The display unit 23 can display management information for concrete pouring. Specifically, the display unit 23 can display plan information 25, implementation information 26, and difference information 27. In addition, the display unit 23 can display the plan information 25, implementation information 26, and difference information 27 for each layer of concrete pouring. The form unit 24 outputs a form on which the implementation information 26 is entered. The form unit 24 is not limited to outputting the implementation information 26, but can also output the plan information 25 and the difference information 27.

[0018] The plan information 25 is information indicating a concrete pouring plan (for example, a pouring start time and a pouring completion time planned in advance). The implementation information 26 is information indicating the implementation results of concrete pouring (for example, the actual pouring start time and pouring completion time, etc.). The difference information 27 is information indicating the difference between the plan information 25 and the implementation information 26 .

[0019] (Measuring Equipment) As shown in FIG. 1, for each of the valves 32, a reflector 36 and a photoelectric sensor 34 are provided. The reflecting portion 36 reflects the light emitted from the photoelectric sensor 34. The reflecting portion 36 is, for example, in the form of a sheet, and is attached to the upper surface of the shutter 35 of the valve 32. The reflecting portion 36 can be displaced in response to the opening and closing of the valve 32, that is, in response to the lateral movement of the shutter 35. The photoelectric sensor 34 is a sensor that detects the open and closed states of the valve 32. A photoelectric sensor 34 is provided for each valve 32, and is fixedly disposed by using a jig (not shown) substantially above each valve 32. Each of the photoelectric sensors 34 is connected to the control device 2 so as to be able to communicate with each other. Fig. 2 is an explanatory diagram of the closed state of the valve 32. As shown in Fig. 2, when the valve 32 is closed, most of the shutter 35 is retracted inside the valve 32. Therefore, the light emitted from the photoelectric sensor 34 is not reflected by the reflecting portion 36, and the photoelectric sensor 34 cannot receive the reflected light. Therefore, the reflecting portion 36 and the photoelectric sensor 34 can detect that the valve 32 is closed. The photoelectric sensor 34 transmits a detection signal indicating the detection result to the control device 2. The control device 2 can determine that the valve 32 is closed based on the detection signal from the photoelectric sensor 34. Fig. 3 is an explanatory diagram of the open state of the valve 32. As shown in Fig. 3, when the valve 32 is in the open state, most of the shutter 35 is exposed from the valve 32. Therefore, the light emitted from the photoelectric sensor 34 is reflected by the reflecting portion 36, and the photoelectric sensor 34 can receive the reflected light. Therefore, the reflecting portion 36 and the photoelectric sensor 34 can detect that the valve 32 is in the open state. The photoelectric sensor 34 transmits a detection signal indicating the detection result to the control device 2. The control device 2 can determine that the valve 32 is in the open state based on the detection signal from the photoelectric sensor 34.

[0020] The reflecting unit 36 ​​and the photoelectric sensor 34 detect the open and closed states of the valve 32 in real time. Therefore, the reflecting unit 36 ​​and the photoelectric sensor 34 can measure the closed time of the valve 32, that is, the time that the closed state of the valve 32 continues. The open / closed state of the valve 32 is transmitted from the photoelectric sensor 34 to the control device 2. This is equivalent to transmitting the closed time of the valve 32 from the photoelectric sensor 34 to the control device 2. The reflecting portion 36 and the photoelectric sensor 34 are components of the "measuring device" in the claims.

[0021] (Refresh) Refreshing is a task of sending fresh concrete to the entire pipe 3 so as to prevent concrete from clogging the inside of the pipe 3. As a method of refreshing, for example, all the valves 32 may be opened and concrete may be allowed to flow from the supply port 31. Alternatively, only one valve 32 may be opened and concrete may be allowed to flow from the supply port 31, and this procedure may be performed sequentially for all the valves 32. Alternatively, as a localized refreshing, only the valve 32 to be refreshed may be opened and concrete may be allowed to flow from the supply port 31. For example, the tablet terminal 1 transmits a control signal indicating that a refresh has been performed to the photoelectric sensor 34 in accordance with the operation of the worker M. The photoelectric sensor 34 resets the closing time of the corresponding valve 32 in response to the control signal.

[0022] [process] The processing of the concrete pouring management system 100 of this embodiment will be described. Fig. 4 is a flowchart of the concrete pouring management method of this embodiment. The processing of Fig. 4 is executed repeatedly during concrete pouring work. The processing of Fig. 4 is a loop processing (step S1) in which the processing of steps S2 to S4 is executed for each valve 32. In the loop process, first, the measuring device measures the closed time of the valve 32 to be managed (step S2). The measured closed time is transmitted from the measuring device to the control device 2. Next, the control device 2 determines whether the closed time of the valve 32 to be managed has exceeded a predetermined time (step S3). If the predetermined time has exceeded (step S3), the control device 2 issues a warning or performs a valve opening process (step S4). Specifically, the warning unit 21 of the control device 2 visually or audibly notifies the possibility of blockage. Alternatively, if the valve 32 is equipped with an actuator, the opening / closing unit 22 of the control device 2 controls the actuator to open the valve 32. In addition, if the valve 32 to be managed is opened due to pouring, the measuring device resets the closed time of the valve 32 to be managed in step S2. If a refresh has occurred, the measurement device resets the closing time of the valve 32 under its management in step S2.

[0023] According to this embodiment, the measuring device can manage the retention time of concrete in the piping portion corresponding to each valve 32. Furthermore, the control device 2 can notify the piping portion that may be clogged based on the closing time of the valve 32. The worker M who notices the notification can open the corresponding valve 32. Furthermore, if the valve 32 is equipped with a predetermined actuator and can automatically open and close the valve 32, the control device 2 can control the actuator to open the valve 32 corresponding to the piping portion that may be clogged. Thus, according to this embodiment, it is possible to prevent clogging of a concrete pipe having a plurality of discharge ports 33. Furthermore, it is not necessary to manage the closing time of the valve 32, and the number of personnel required for pouring concrete can be reduced. Furthermore, since the stagnation time of concrete in the refreshed piping section becomes zero, the stagnation time of concrete can be appropriately managed even when the valve 32 is opened and closed multiple times. Moreover, according to this embodiment, the mechanism for determining whether the valve 32 is open or closed can be realized with a simple configuration.

[0024] [Specific examples of concrete pouring management] A specific example of concrete pouring management by the pouring management system 100 of this embodiment will be described. Fig. 5 is an example of a screen display of the tablet terminal 1. The screen of the tablet terminal 1 is divided into a <<layer number>> area, a <<valve opening / closing>> area, and a <<blockage prevention>> area. The display field 51 in the <<Layer Number>> area displays the number of the layer currently being poured. The "Valve No." button 52 in the <<Valve Opening / Closing>> area is provided for each valve 32. For example, when the worker M taps the No. 3 "Valve No." button 52, the tablet terminal 1 stores that the No. 3 valve 32 is open and is currently being poured. The tablet terminal 1 also records the timing when the "Valve No." button 52 is tapped as the concrete pouring start time. The tablet terminal 1 also records the concrete pouring end time of the valve 32 that was open up until that point and has now been changed to a closed state. The tablet terminal 1 transmits to the control device 2 information indicating the valve 32 currently being poured, information indicating the concrete pouring start time, and information indicating the concrete pouring end time. The display field 53 in the <<Valve Open / Close>> area displays the number of the valve 32 currently being poured. The display field 54 in the <<Valve Open / Close>> area displays the scheduled time for starting pouring for the valve 32 currently being poured. The tablet terminal 1 can read out the plan information 25 from the control device 2 and obtain the scheduled time for starting pouring. The display field 55 in the <<Valve Open / Close>> area displays the implementation time of starting concrete pouring for the valve 32 currently being poured. The tablet terminal 1 transmits the implementation time of starting concrete pouring to the control device 2, and the control device 2 can update the implementation information 26 with the implementation time of starting concrete pouring. In the display field 56 of the <<Clogging Prevention>> area, the number of the valve 32 located at the very tip (most downstream) of the valves 32 in the pipe 3 is displayed as the “Tip Valve No.”. In the display field 57 of the <<Clogging prevention>> area, the duration of the closed state of the valve 32 corresponding to the "tip valve number" is displayed as the "blockage (elapsed) time." The blockage (elapsed) time is counted when pouring of concrete is started at a valve other than the valve 32 corresponding to the "tip valve number." The blockage (elapsed) time is reset when pouring of concrete is started at the valve 32 of the tip valve number. The blockage (elapsed) time is also reset when a refresh is performed. If the blockage (elapsed) time exceeds 30 minutes, the warning unit 21 of the control device 2 displays the blockage (elapsed) time in red.

[0025] Fig. 6 is an example of a screen display of planning information, implementation information, and difference information. The display unit 23 of the control device 2 can display management information in a table format that summarizes planning information 25, implementation information 26, and difference information 27. The management information is composed of a "layer number" column, a "valve number" column, a "pouring plan" column, and a "actual pouring" column. The "Layer Number" column displays the layer number of the concrete being poured. In the "Valve No." column, a number for identifying each of the valves 32 is displayed. The "Pouring Plan" field displays information about the concrete pouring schedule. The "Pouring Plan" field is divided into a "Start Time" field, a "Completion Time" field, a "Pouring Time (min)" field, and a "Refresh" field. The “Start Time” column displays the scheduled time for starting pouring at each valve 32. The “Completion Time” column displays the scheduled time for completion of pouring at each valve 32. The “Pouring time (min)” column displays the estimated time required for pouring at the corresponding valve 32. The "Refresh" field displays whether or not refreshing is performed. In the example of Fig. 6, refreshing is performed when pouring is performed at the No. 1 valve 32 (when the No. 1 valve 32 is open). The various information in the “Battle Plan” column constitutes plan information 25.

[0026] The "Actual pouring" column displays information showing the results of pouring. The "Actual pouring" column is divided into a "Start time", a "Completion time", a "Pouring time (min)", and a "Difference (min)" column. The "Start Time" column displays the time when pouring begins at each valve 32. The “Completion Time” column displays the time when pouring was completed for each valve 32. The “Pouring time (min)” column displays the time required for pouring at each valve 32. The "Difference (minutes)" column shows the difference between the time displayed in the "Completion time" column in the "Pouring plan" column and the time displayed in the "Completion time" column in the "Actual pouring" column. The various information in the "Start time", "Completion time", and "Pouring time (min)" columns of the "Implemented pouring" column constitute implementation information 26. In addition, the information in the "Difference (min)" column of the "Implemented pouring" column constitutes difference information 27. The report unit 24 can output various information in the "Start time" column, the "Completion time" column, and the "Pouring time (min)" column of the "Actual pouring" column. The report unit 24 can also output various information in the "Pouring plan" column and information in the "Difference (min)" column of the "Actual pouring" column.

[0027] According to this example, the progress of concrete pouring can be easily confirmed, and concrete pouring records can be easily managed.

[0028] [Variations] (a): The shape of the piping 3 is not limited to a horizontal shape with T-shaped valves 32 connected, but may be, for example, an octopus-like shape with three or more branches branching out from one point of the piping 3, or an L-shape. (b): It is preferable that the shutter 35 is disposed at a position very close to the root of the branching point of the valve 32. When the shutter 35 is spaced downward from the root of the valve 32 as in the configurations of Figs. 2 and 3, concrete is likely to stagnate between the shutter 35 and the valve 32 when the valve 32 is closed. Therefore, it becomes more necessary to perform refreshing after opening each valve 32. When the shutter 35 is disposed at a position very close to the root of the branching point of the valve 32, the upper surface of the shutter 35 and the inner wall surface of the pipe 3 are almost flush with each other. Therefore, even when the valve 32 is closed, concrete is hardly stagnated inside the valve 32 (on the upper surface of the shutter 35) due to the transport of concrete by pouring in other valves 32. As a result, the number of times of refreshing can be reduced, and the time required for pouring can be shortened.

[0029] (c) It is also possible to realize a technology that appropriately combines the various technologies described in this embodiment. (d) The software described in the present embodiment can be realized as hardware, and vice versa. (e) In addition, the components of the present invention can be modified as appropriate without departing from the spirit of the present invention. [Explanation of symbols]
