  The present invention relates to a concrete placement management method, and more particularly to a management method in a concrete compaction process.

Conventionally, in dam concrete, a vibrator that vibrates at high frequency, a so-called vibrator, is used as a machine for compacting the placed concrete. The compaction by the vibrator has been performed by the operator operating the compacting machine with the vibrator attached according to the instruction of the person in charge of placing. However, because the concrete placement range in dam construction is wide, problems such as oversight of the compaction position and inadequate compaction due to insufficient compaction due to the compacted concrete with small slump test values are likely to occur. there were. Such a compaction failure may cause cracks, junkers, and filling failures after the concrete is cured, and may cause integration, strength, durability, and peeling as a casing. Patent Documents 1 to 5 disclose a technique for managing concrete compaction to prevent a concrete compaction failure in dam construction.
However, in the inventions according to Patent Documents 1 to 5, etc., although the compaction of each concrete placed in a predetermined range can be managed, when it is completed as one structure, it is integrated as a frame. Performance such as strength, durability, and peeling cannot be obtained.

The compacting machine information acquisition device 2 is provided in a compacting machine 11 that compacts concrete. As shown in FIGS. 1A and 1B, a compacting machine 11 is a vehicle construction machine to which a plurality of vibrators 10 for compacting concrete are attached instead of a shovel of a construction machine called a hydraulic excavator. The compacting machine 11 extends from the vehicle body 12 and includes a first arm 14 rotatably attached to the vehicle body 12 and a second arm 15 rotatably attached to the first arm 14. Is provided. At the tip of the second arm 15, a shaft support 18 for rotatably mounting a plurality of vibrators 10 is provided, and the vibrator 10 is attached via the shaft support 18. The vibrator 10 is a vibrator formed in a rod shape, and has a predetermined interval along the extending direction of the rotation base portion 18A that is rotatably attached via the shaft support portion 18 on the distal end side of the second arm 15. And the extending directions are the same. In this example, as shown in FIG. 1B, a total of four vibrators 10 are provided in a fork shape. Note that the number and arrangement shape of the vibrator 10 are not limited to this, and may be set as appropriate.
The vibrator 10 is operated to be turned on and off so as to continuously operate, for example, during the compacting operation. For example, the vibrator 10 is turned on by the operator's operation at the start of compaction work or at the start of work in each compaction section, and starts operating. At the end of compaction work or in each compaction section, the vibrator 10 starts operating. At the end of the work, the switch is turned off to stop the operation.
It should be noted that the on / off operation of the switch of the vibrator 10 may be performed at an appropriate timing, but the on operation should be performed so that the vibrator 10 operates at least before the vibrator 10 is inserted into the concrete. It is preferable that the off operation is performed at least after the vibrator 10 is pulled out from the concrete.

The compacting machine information acquisition apparatus 2 includes a machine position detection unit 21, a posture detection unit 22, and an insertion depth detection unit 23.
The machine position detecting means 21 is provided for measuring the position of the compacting machine 11. For example, GNSS (Global Navigation Satellite Systems) is used for the GNSS, which includes a plurality of GNSS satellites 25 and a base station. A GNSS fixed station 26 fixedly installed as a station and a GNSS mobile station 27 movably installed are output from a plurality of GNSS satellites 25 and the GNSS fixed station 26. The coordinate position on the earth such as latitude, longitude, and altitude, which is the position information of the GNSS mobile station 27, is acquired in real time by the GNSS mobile station 27. The GNSS mobile station 27 connects the antenna 27A and the receiver 27B. The antenna 27A is provided, for example, at two locations on the left and right of the rear portion of the vehicle body 12 of the compacting machine 11, and includes a plurality of GNSS. Signals received from the star 25 and the GNSS fixed station 26 are transmitted to the receiver 27B, which receives coordinates such as the latitude, longitude, and altitude of the compacting machine 11 based on the signal input via the antenna 27A. In this embodiment, since two antennas 27A are provided in the rear part of the vehicle body 12 so as to be symmetrical with respect to the longitudinal axis, in addition to the coordinate position of the compacting machine 11, The roll angle of the vehicle main body 12 can also be acquired, and the acquired coordinate position of the compacting machine 11 and the roll angle indicating the attitude of the vehicle main body 12 are output to the compaction management device 4.

  The antenna 27A may be provided alone in the compacting machine 11. In this case, it is possible to detect the inclination of the vehicle body 12 in the width direction by separately providing a roll angle detection means for detecting the roll angle. In the present embodiment, an example in which GNSS is used as a positioning means is shown. However, the position of the compacting machine 11 is measured in real time using a total station using a surveying instrument equipped with a communication device instead of the GNSS mobile station 27. Alternatively, the position of the compacting machine 11 may be measured using a conventional GPS system.

  The posture detection means 22 detects the posture of the vibrator 10 provided in the compacting machine 11. The posture detection means 22 includes, for example, a plurality of inclination sensors 22A; 22B, a rotary encoder 22C, and a pitch sensor 22D. The inclination sensors 22A; 22B are provided in the first arm 14 and the second arm 15, respectively, and output the inclination angles of the arms 14; 15 with respect to the horizontal direction as detection values. The rotary encoder 22 </ b> C is provided on the shaft support 18 at the tip of the second arm 15, and outputs the angle of the vibrator 10 with respect to the second arm 15 as a detection value. The pitch sensor 22D is provided in the vehicle main body 12, and outputs the front and rear inclination angles (pitch angles) of the vehicle main body 12 as detection values. The detection values of the inclination sensors 22A and 22B, the rotary encoder 22C, and the pitch sensor 22D are output to the compaction management device 4. In the compaction management device 4, the posture of the vehicle main body 12 of the compacting machine 11 such as pitching or rolling, the position of the tip of the second arm 15 to which the vibrator 10 is attached, and the second arm 15 are based on each detected value. The posture of the vibrator 10 with respect to is calculated.

  The insertion depth detection means 23 detects the actual insertion depth of the vibrator 10 into the placed concrete. As the insertion depth detection means 23, for example, a distance sensor that measures a distance by irradiating a concrete surface with a laser is used. The insertion depth detection means 23 is attached to a rotating base 18A that rotates together with the vibrator 10 at the shaft support 18 of the second arm 15 so that the laser irradiation direction (measurement direction) is parallel to the extension direction of the vibrator 10. The detection value X detected by the insertion depth detection means 23 is output to the compaction management device 4. Based on the detected value X, the compaction management device 4 determines whether or not the vibrator 10 has been inserted into the concrete, whether or not the vibrator 10 has been compacted, and whether or not the concrete has been inserted into the concrete. In addition, as shown in FIG.1 (b), the distance from the measurement origin 23A of a distance sensor to the front-end | tip of the vibrator 10 is beforehand memorize | stored in the memory | storage means outside a figure, and the insertion of the vibrator 10 to the above-mentioned concrete is carried out. It is used as a reference length when determining the presence / absence, the beginning and end of compaction by the vibrator 10, and the quality of insertion into concrete.

  The compaction management device 4 is a so-called computer, which is a CPU as a calculation means provided as hardware resources, a ROM and a RAM as storage means, and a communication means that enables data input and output with the storage means. Equipped with an input / output interface. The storage means stores a program for operating the compaction management device 4 configured by a computer as each means described later and various data necessary for the operation. The CPU functions as means described later by executing processes described later according to a program stored in the storage means. The compaction management device 4 is connected to the above-described detection means and a display device 5 for displaying information processed according to the program.

The storage means of the compaction management device 4 stores concrete placement design image data, construction area map data, vibrator specification data, compaction influence range data, compaction time setting data, and the like in advance.
The concrete placement design image data is a database of concrete placement order, placement positions, and concrete property information at each placement position planned in advance. The concrete property information is numerical data representing the workability of concrete obtained by test construction, slump test, and the like.
The construction area map data is a map of the construction area 3 shown in FIG. 1A, and coordinate position information is associated with each position on the map. The coordinate position information is information on latitude, longitude, and altitude obtained from the GNSS satellite 25 and the GNSS fixed station 26.

  The vibrator specification data is data indicating the configuration of the vibrator 10 attached to the compacting machine 11 described above. For example, the quantity and arrangement of the vibrator 10. In this embodiment, the specification of the vibrator will be described on the assumption that four vibrators 10 are arranged in a fork shape as shown in FIGS. 1 and 3. However, the present invention is not limited to this, and one or a plurality of vibrators are used. 10 may be arranged in a triangular shape, a rectangular shape, a trapezoidal shape, or the like.

The compaction influence range data is a database for defining a range in which the vibration of the vibrator 10 affects for each property of concrete. FIGS. 3A and 3B are conceptual diagrams showing a compaction influence range R set in accordance with the properties of concrete. A two-dot chain line shown in the figure indicates a compaction influence range R. The compaction influence range R is set as a three-dimensional region in consideration of the extension direction of the vibrator 10 and the direction orthogonal to the extension direction. Specifically, it is formed by a surface direction range Rh that affects the direction along the surface of the placed concrete, and an extension direction range Rf that affects the extension direction of the vibrator 10 in the surface direction range Rh. A three-dimensional region.
The surface direction range Rh and the extension direction range Rf are set based on past data and test construction data.
In the compaction influence range data, a plurality of compaction influence ranges R are defined as a database for each property of concrete that can be placed in consideration of the number, performance, and arrangement shape of vibrators 10 to be used.

  The compaction time setting data is a database for setting an appropriate operation time (consolidation time) according to the properties of the concrete when the concrete is compacted by the vibrator 10. An appropriate operation time of the vibrator 10 is a time sufficient for the voids in the concrete, the excess water region, and the concrete to flow, so that the cement paste and the aggregate constituting the concrete are not separated.

  The compaction management device 4 includes information related to the compacting machine 11 obtained from the compacting machine information acquisition device 2 described above, and placement information obtained from the concrete placement information providing device 7 provided in the construction area 3. Based on the above, management processing necessary for the compacting operation of the concrete by the compacting machine 11 is executed.

Here, the concrete placement information providing device 7 includes a concrete placement position, a placement thickness measuring means 70 for measuring the placement thickness of the placed concrete, a measured concrete placement position, and And a communication means 71 for outputting the concrete casting thickness to the compaction management device 4.
The placement thickness measuring means 70 is provided in a support means (not shown) in the construction area 3 where the concrete is placed, and measures the change in the distance before and after placing at the placement position of the concrete, and the concrete placement thickness. Measure. As the casting thickness measuring means 70, a measuring instrument capable of measuring the concrete casting thickness in a non-contact manner, for example, a laser distance measuring device may be used.

  Hereinafter, a specific configuration and processing of the compaction management device 4 will be described. As shown in FIG. 2, the compaction management device 4 includes a compaction position acquisition unit 41, an insertion depth setting processing unit 42, a compaction time setting processing unit 43, an insertion depth monitoring unit 44, and a compaction. Time monitoring means 45, display output processing means 46, and compaction information recording means 47 are provided.

The compaction position acquisition unit 41 compares the detection value X input from the insertion depth detection unit 23 with the threshold value α, and determines that the vibrator 10 is inserted when the detection value X falls below the threshold value α. When the detected value X is equal to or greater than the threshold value α, it is determined that the vibrator 10 is not inserted. Here, as the threshold value α, for example, a length L1 from the measurement origin 23A to the tip 10A of the vibrator 10 is set.
When it is determined that the vibrator 10 is inserted, the coordinate position where the vibrator 10 is inserted is based on the coordinate position input from the machine position detection unit 21 and the detection value input from the posture detection unit 22. To get. Specifically, with reference to the coordinate position of the compacting machine 11 obtained by the GNSS mobile station 27, the posture detection means 22 is input from the inclination sensors 22A and 22B provided on the first arm 14 and the second arm 15. Detection value, distance from the base of the first arm 14 to the antenna 27A, the lengths of the first arm 14 and the second arm 15, the arrangement shape of the vibrator 10, and the tip of the vibrator 10 from the shaft support portion 18 of the second arm 15. The insertion position P of the vibrator 10 is calculated on the basis of the vehicle information regarding the compacting machine 11 such as the distance up to. The position of vibrator 10 refers to the coordinate position of the tip of vibrator 10. When a plurality of vibrators 10 are mounted on the compacting machine 11 as in the present embodiment, the centroid Q in the arrangement shape formed on the distal end side of the plurality of vibrators 10 is processed as the position of the vibrator 10 (FIG. 3 (a)). Thereby, insertion position P when vibrator 10 is inserted in concrete is specified automatically.

  FIG. 4 is a conceptual diagram when the optimum insertion depth K of the vibrator 10 is set by the insertion depth setting processing means 42. The insertion depth setting processing means 42 sets the optimum insertion depth K of the vibrator 10 according to the insertion position P (see FIG. 5) of the vibrator 10 calculated by the compaction position acquisition means 41. The insertion depth setting processing means 42 refers to the concrete placement design image data, and acquires the concrete property information at the calculated insertion position P of the vibrator 10. Next, the compaction influence range data corresponding to the acquired properties of the concrete is acquired with reference to the compaction influence range data. Next, the concrete placement thickness information input from the placement information providing device 7 is referred to, and the concrete placement thickness M at the position is acquired. Then, the optimum insertion depth K is set according to whether the input insertion position P of the vibrator 10 is the first layer or the second layer or more.

  When the insertion position P of the vibrator 10 is one of the first layer block A, block B and block C (the lowest block) placed on the rock, the insertion depth setting processing means 42 As shown in FIG. 4B, the optimum insertion depth K is set so that the lower end side of the extension direction range Rf of the compaction influence range R reaches the rock mass without the vibrator 10 being in direct contact with the rock mass.

  4A, when the insertion position P of the vibrator 10 is on the block A that has been compacted first, the insertion depth setting processing means 42 c) Optimum insertion of the vibrator 10 so that the tip of the vibrator 10 passes through the block D in which concrete is newly placed and enters the block A that has been compacted first by a predetermined length J as shown in c). Set the depth K. That is, the optimum insertion depth K is set so that the lower end side of the extension direction range Rf extends to the concrete cast in the block A. The set insertion optimum depth K is output to the insertion depth monitoring means 44.

  In this way, by setting the optimum insertion depth K so that the extension range Rf of the vibrator 10 extends to the block A located in the lower stage when the block D of the second layer located in the upper stage of the block A is compacted. In addition to the compaction of the block D, since the block D and the block A are uniformly compacted so as to be integrated at the boundary between the block D and the block A, the block A and the block D are tightly integrated after curing, It becomes concrete with excellent strength as a frame.

  In the compaction time setting processing means 43, the concrete property information on the insertion position P of the vibrator 10 is acquired by referring to the concrete placing design image data. Then, referring to the compaction time setting data, a compaction time T1 corresponding to the acquired property of the concrete is acquired, and this is set as the compaction time T1. The set compaction time T1 is output to the compaction time monitoring means 45.

  The insertion depth monitoring means 44 compares the detection value X inputted from the insertion depth detection means 23 with the optimum insertion depth K set by the insertion depth setting processing means 42, and the detected value X is the optimum insertion. When the depth K is exceeded, it is determined that compaction is started by the vibrator 10, and when the detected value X is equal to or less than the optimum insertion depth K, it is determined that compaction is completed. When the start of compaction is determined, the display output processing means 46 is notified that the vibrator 10 has been inserted to a predetermined compaction depth. In this embodiment, compaction is started when the detected value X detected by the insertion depth detection means 23 exceeds the optimum insertion depth K. However, a length β shorter than the optimum insertion depth K is set. It is also possible to start compaction when it is set and exceeds this length β.

  The compaction time monitoring unit 45 starts the timing process when a signal for notifying the start of compaction is input from the insertion depth monitoring unit 44, and performs the timing process when the detected value X falls below the threshold value γ. finish. For example, a value smaller than the optimum insertion depth K may be set as the threshold γ. Further, when the compaction time T1 set by the compaction time setting processing unit 43 has elapsed after the start of timing, the compaction time monitoring unit 45 notifies the operator of the completion of compaction at that position. The time measurement process is performed so as to add time, for example. Further, the compaction time monitoring means 45 informs that the compaction time T1 has been reached when the timing has been started, and when the preset compaction time T1 has been reached, when the clocking has started. The signal is output to the display output processing means 46.

FIG. 5 is a diagram showing a display example displayed on the monitor 8 of the display device 5 by the display output processing means 46. The display output processing means 46 executes a process for changing the display image displayed on the display device 5 in accordance with the progress of the compacting operation.
As shown in FIG. 5, the display output processing means 46 performs processing for displaying the construction area 3 on the display device 5 to indicate the compaction location to the operator, and the current position F1 of the vibrator 10 in the construction area 3. The process for displaying, the process for displaying the compacted position F2 in the construction area, and the like are executed.

For example, at the site of dam construction, since construction is simultaneously performed at a plurality of locations in the construction area 3, a map of the entire construction area 3 is displayed on the monitor 8, and a plurality of sections constituting the construction area 3 are displayed. When the operator selects a section to be compacted by touching or the like, display processing such as enlarging the section is performed.
Further, as shown in FIG. 5, when the end of compaction is input from the compaction time monitoring means 45, the display output processing means 46 is a position corresponding to the coordinate position where compaction is completed on the block map. The display process is performed. In this display process, for example, for details that have been compacted in a color different from the background color, the compaction influence range R (surface direction range Rh) acquired when compacting the position is shown together with the coordinate position where compaction has been completed. For example, the visibility of the operator can be improved by displaying in a color different from the background color. Further, when the surface direction range Rh overlaps due to compaction at a plurality of places, the operator can be suitably informed of the compaction status by performing display processing so as to emphasize the overlapping portion F3. That is, when there is no overlapping portion F3, it can be confirmed that there is no continuity in compaction.
The display processing by the display output processing means 46 is an example, and can be appropriately changed by an operator's operation. For example, when the vibrator 10 is inserted, the posture of the vibrator 10 detected by the posture detection means 22 and the actual insertion depth are displayed on the monitor 8, so that the operator 10 can be compacted intuitively. Can inform the status of work.

  The compaction information recording means 47 records information related to the compaction work when the vibrator 10 is actually operated to perform the compaction work. The information related to compaction work includes the date and time of compaction, the number of the section where compaction was performed, the coordinate position where the vibrator 10 was actually inserted in the section, the actual operation time of the vibrator 10 (consolidation time monitoring means) 48), and the like.

The display device 5 is provided so as to be visible from the cockpit of the compacting machine 11. The display device 5 includes, for example, a monitor 8 and indicator lamps 9A and 9B. The monitor 8 superimposes and displays the compacted location and the current position of the compacting machine 11 (position of the vibrator 10) on the map of the construction area 3 output from the display output processing means 46. For example, a display capable of color display is applied to the display device 5. More preferably, a touch panel display that functions as input display means may be employed.
The indicator lamp 9A is turned on or off based on a signal output from the insertion depth monitoring unit 44 to the display output processing unit 46. The indicator lamp 9B is turned on or off based on a signal output from the compaction time monitoring unit 45 to the display output processing unit 46.
Therefore, the operator can reliably compact the concrete by performing the compacting operation of the placed concrete based on the contents displayed on the display device 5.

  The communication device 6 is a wireless communication device mounted on the compacting machine 11. The communication device 6 outputs the contents displayed on the display device 5 and information on the compacting operation to an office at a construction site, an office provided at a location away from the construction site, or the like. By sharing information related to the compaction work in this manner, workers other than the operator can monitor the compaction work, so that the compaction work can be performed more reliably.

FIG. 6 is a flowchart showing the processing procedure of the compaction management device 4. The compaction management device 4 operates with the insertion of the vibrator 10 into the concrete by the operation of the operator as a trigger.
[Detection of vibrator insertion]
(S101)
Based on the detection value X output from the insertion depth detection means 23, it is determined whether or not the vibrator 10 is inserted into the concrete. When the detection value X output from the insertion depth detection means 23 is below the threshold value α, it is determined that the vibrator 10 has been inserted, and the process proceeds to S102. Further, when the detected value X is equal to or greater than the threshold value α, the processing is returned to indicate that the vibrator 10 is not inserted, and monitoring of whether the vibrator 10 is inserted into the concrete is continued.

If the position is not in the second layer or more, that is, the first layer The process moves to S107. Here, the case where it is the position of the second layer or more is a case where there is an uncured block compacted at the lower side (lower stage side) like the block D shown in FIG. .
(S106)
In response to determining that the concrete placement position is the second or higher layer in S105, the extension direction range Rf is based on the compaction influence range R and the placement thickness M obtained in S104. The optimum insertion depth K is set so that the lower end side of this includes the concrete into which the vibrator 10 is inserted and the concrete below it, and the process proceeds to S108. That is, the optimum insertion depth K is set so that the upper concrete to be compacted will be penetrated and the tip of the vibrator 10 enters a predetermined length into the lower concrete that has been compacted first.
(S107)
When it is determined in S105 that the concrete placement position is not the second or higher layer position, the extension direction range Rf is determined based on the compaction influence range R and the placement thickness M obtained in S104. The optimum insertion depth K is set so that the lower end side reaches the rock surface, and the process proceeds to S108.

[Setting compaction time]
(S108)
With reference to the hit design image data from the storage means, the compaction time T1 corresponding to the property of the concrete acquired in S103 is set, and the processing is shifted. With the above processing, the setting of the optimum insertion depth K of the vibrator 10 and the compaction time T1 at the insertion position P of the vibrator 10 is completed.

(S109)
The actual insertion depth of the vibrator 10 inserted into the concrete by the operation of the operator, that is, the detection value X input from the insertion depth detection means 23 is compared with the set optimum insertion depth K of the vibrator 10. If the detected value X reaches or exceeds the optimum insertion depth K, the process is copied to S110. If the detected value X has not reached, the process (S109) is continued.

(S111)
Based on the start of compaction by the vibrator 10 in S109, the timekeeping processing by the compaction time monitoring means 45 is started so as to perform compaction for the compaction time T1 set in S108, and display A signal indicating that compaction has started is output to the output processing means 46, and the process proceeds to S112. Thereby, in the display output process means 46, the process which lights the indicator lamp 9B is performed.
(S112)
Based on the start of the time measuring process in S111, it is determined whether the compaction time T1 has elapsed. If it has elapsed, the process proceeds to S113, and if not, the process (S112) is repeated. By repeating this process, the operator is informed that compaction should be continued.
(S113)
Based on the fact that the compaction time T1 by the vibrator 10 has elapsed in S112, the display output processing means 46 is notified of the completion of compaction, and the process proceeds to S114. Thereby, the display output processing means 46 turns off the indicator lamp 9A.
(S114)
When the operator who has visually confirmed that the indicator light 9A is turned off operates to pull out the vibrator 10,
If the detection value X detected by the insertion depth detection means 23 is below the threshold γ, the process proceeds to S115. If the detection value X is equal to or greater than the threshold γ, the process (S114) is continued.
(S115)
Based on the determination in S114, the timing process is terminated, the display output processing unit 46 is notified of the termination of the timing process, and the process proceeds to S116.
(S116)
Based on the completion of the time measurement process in S115, the actual compaction time and insertion depth measured by the time measurement process are stored in the storage means in association with the insertion position P, and tightening is performed at the insertion position P. A display indicating that the hardening is completed is additionally displayed on the monitor 8, and the process proceeds to S101.
By repeating the processing of S101 to S116, the position coordinates of the insertion position P, the compaction time T1 and the actual insertion depth (detected value X) each time the vibrator 10 is inserted are linked and stored. It is possible to confirm the compaction history for each insertion position P after completion of the concrete placement.

As described above, according to the management method according to the present embodiment, the optimum insertion depth K and the compaction time are considered in consideration of the compaction influence range R of the vibrator 10 corresponding to the properties of the concrete at the position where the vibrator 10 is inserted. Since T1 is set, an appropriate compaction effect can be obtained.
In addition, since the optimum insertion depth K is set so that the concrete positioned immediately below the vibrator 10 is affected by compaction, it is possible to enhance the integration with the concrete positioned below. Become.
In addition, in the operation of inserting the vibrator 10 into the concrete, when the vibrator 10 reaches the set optimum insertion depth K so as to support the compacting operation by the operator, the timing processing of the compaction time T1 is started. This is displayed on the display device 5 and, when the compaction time T1 is reached, an indication of the completion of compaction is displayed, so that uniform compaction can be performed. In addition, after compaction, the compacted position is displayed on the monitor 8 of the display device 5 including the compaction influence range R. Therefore, it can be visually recognized whether the concrete is affected by compaction. As a result, forgetting compaction and poor compaction can be reliably prevented. Further, every time compaction is completed, the date and time when compaction is performed, the block number of the compacted insertion position P, the coordinate position where the vibrator 10 is actually inserted, the actual operation time of the vibrator 10 and the vibrator Since the insertion depth of 10 is recorded in the storage means as compaction information, compaction history (consolidation traceability) can be verified even after construction.

In the above embodiment, the concrete casting thickness M is measured by the casting thickness measuring means 70. However, based on the detection value X output from the insertion depth detecting means 23, the vibrator 10 is used. You may make it acquire concrete casting thickness M in the position which inserts.
For example, in the case of concrete placed on the bedrock, the coordinate position at each position on the bedrock is known by surveying or the like. Further, the coordinate position of the tip of the vibrator 10 can be acquired by the machine position detecting means 21, the attitude detecting means 22, and the insertion depth detecting means 23.
Therefore, the casting thickness before compacting of the concrete placed on the rock can be calculated based on the coordinate position obtained by surveying and the coordinate position immediately before the vibrator 10 is inserted. Based on the calculated casting thickness M before compaction, the optimum insertion depth K is set and compaction is performed. Then, when the vibrator 10 is pulled out from the concrete after compaction, the coordinate position of the tip of the vibrator 10 immediately before being pulled out is stored. Thereby, it is possible to perform compaction with higher accuracy in consideration of a change in the casting thickness of the concrete before and after compaction.
That is, when each block is compacted, all the coordinate positions of the tip of the vibrator 10 immediately before the vibrator 10 is pulled out are stored, the average thickness of the concrete after compaction is calculated, and compaction is performed based on this. The optimum insertion depth K can be set more accurately by calculating the casting thickness before compacting of the concrete placed on the subsequent concrete.

  In the above embodiment, the insertion depth detection means 23 detects the insertion of the vibrator 10 into the concrete. However, an insertion detection means is provided separately to detect the insertion of the vibrator 10 into the concrete. May be. As the insertion detection means, for example, the sound sensor may be configured to detect the insertion of the vibrator 10 into the concrete and the extraction from the concrete.
