Description

The present disclosure relates to a compaction management method and a compaction management system for compacted filling materials.

Patent Document 1 describes an embankment rolling compaction management method in which a roller, which is a heavy iron rigid body, is vibrated by an exciting means, and the acceleration when the ground is compacted by the vibrated roller is measured to perform compaction management. ing. In this embankment rolling compaction management method, the frequency spectrum of the measured acceleration is subjected to high-speed Fourier analysis by utilizing the characteristic that the high-frequency component of acceleration increases as the ground becomes harder, and the hardness of the ground is used by using an index called turbulence rate. The vibration acceleration of the roller corresponding to is quantitatively expressed.

Further, in the above embankment rolling compaction management method, the relationship between the turbulence rate and the index derived in advance based on the numerical simulation based on the equation of motion of the two-mass vibration model of the roller vibrating on the ground, and the index and the ground spring. The ground rigidity data is continuously acquired by using the relational expression of the constant. The ground rigidity data includes the ground spring constant, the ground reaction force coefficient, and the ground deformation coefficient. In this embankment rolling compaction management method, the embankment density is estimated from the acceleration by obtaining the relationship between the turbulence rate and the ground density in advance by experiments.

Japanese Patent No. 3908031

In the above-mentioned embankment rolling compaction management method, a huge amount of ground rigidity data including the ground spring constant, the ground reaction force coefficient, and the ground deformation coefficient is acquired at the same time as the compaction of the embankment material. However, not all of the ground rigidity data acquired in large quantities is used, and there is wastefully acquired data. Therefore, there is a concern that a storage device such as a hard disk may be pressed by acquiring a large amount of data. Another problem is that the processing load for extracting necessary data from the enormous amount of acquired data is high.

Furthermore, when the ground rigidity data is acquired and compaction management is performed at the same time as the compaction of the filling material, the vibrating roller cannot concentrate on compaction, so that it takes time instead of compaction and compaction management. .. That is, since the vibrating roller that compacts the filling material must also perform compaction management, there is a problem that it takes time to acquire data and the efficiency is not good. Further, if the compaction management is performed together with the compaction, the compaction state of the filling material may be deteriorated when measuring the data of the ground rigidity, so that there is room for improvement in the accuracy of the compaction quality.

The present disclosure provides a compaction management method and a compaction management system capable of efficiently performing compaction and compaction management of a filling material and maintaining high quality of compaction accuracy. The purpose.

The compaction management method according to the present disclosure is a compaction management method for compacting and managing the compaction material, which includes a step of compacting the compaction material with a first roller which is a vibrating roller and a first roller. After the compaction by the above is completed, a step of running the second roller on the filling material and acquiring the compacting information of the filling material by the second roller is provided.

In this compaction management method, first, the first roller, which is a vibrating roller, compacts the filling material. Then, after the compaction of the filling material by the first roller is completed, the second roller different from the first roller runs on the filling material to acquire the compaction information. Therefore, the first roller compacts the filling material, and the second roller, which is different from the first roller, acquires the compaction information, so that the first roller concentrates on compaction and the second roller compacts. You can concentrate on getting information. Therefore, since the first roller concentrates on compaction and the second roller concentrates on acquiring compaction information, it is possible to eliminate the need to acquire a huge amount of compaction management data. As a result, since the first roller can concentrate on compaction, it is not necessary to acquire compaction management data, and the second roller concentrates on compaction management to obtain the minimum necessary compaction information. Acquisition can be sufficient. That is, since the second roller does not need to perform compaction and can perform sufficient quality control by acquiring the minimum necessary compaction information, it is necessary to acquire a huge amount of data and to obtain a huge amount of data. Data extraction can be eliminated. Therefore, by performing compaction management by the second roller after the first roller has compacted, the time required for data acquisition and the like can be reduced, so that compaction and compaction management can be performed efficiently. Can be done. Further, since the second roller concentrates on the compaction management, the influence on the compaction state of the filling material at the time of the compaction management can be suppressed, so that the quality of the compaction can be improved.

Further, the second roller may acquire compaction information while traveling without vibration. In the present specification, "vibration-free" means a state in which vibration for compaction is not generated, and when only the weight of the roller is added to the building material, or when the roller is simply driven on the building material. Including the case of letting. When the second roller acquires compaction information while traveling without vibration, the second roller does not compact the filling material, so that the influence on the compacting state of the filling material can be suppressed more reliably. it can. Therefore, the quality of compaction can be further improved.

Further, the second roller may be a horizontal vibration roller that generates vibration in the horizontal direction. In this case, the horizontal vibration roller that generates vibration in the horizontal direction can be effectively used as the second roller for compaction management.

Further, the weight of the second roller may be smaller than the weight of the first roller. In this case, since the weight of the second roller is small, it is possible to more efficiently manage the running and compaction of the second roller on the building material.

The compaction management system according to the present disclosure is a compaction management system that performs compaction and compaction management of the filling material, and operates the first roller, which is a vibrating roller, and uses the first roller to load the filling material. The first roller operating unit for compaction and the second roller operation for running the second roller on the filling material after the compaction by the first roller is completed and acquiring the compacting information of the filling material by the second roller. It has a part and.

In this compaction management system, the first roller operating unit operates the first roller, which is a vibrating roller, to compact the filling material, and after the compaction of the filling material is completed, the second roller operating unit operates. The second roller, which is different from the first roller, is operated to acquire compaction information. Therefore, as in the compaction management method described above, the first roller compacts the filling material, and the second roller acquires the compaction information, so that the first roller compacts the filling material. It is possible to eliminate the need for acquisition of compaction management data. Then, the second roller does not need to perform compaction, and can acquire the minimum necessary compaction information and perform sufficient quality control. Further, by performing the compaction management by the second roller after the first roller performs the compaction, the compaction and the compaction management can be efficiently performed, and the compaction state of the filling material at the time of the compaction management is performed. Since the influence on the compaction can be suppressed, the accuracy of the compaction quality can be improved. Further, by operating each of the first roller and the second roller by each of the first roller operating unit and the second roller operating unit, compaction of the filling material by the first roller and compaction information by the second roller Since it is possible to automate the acquisition of the compaction, it contributes to further efficiency of compaction and compaction management.

According to the present invention, compaction and compaction management of the filling material can be efficiently performed, and compaction can be maintained at high quality.

Hereinafter, the compaction management method and the embodiment of the compaction management system according to the present disclosure will be described in detail with reference to the drawings. In the description of the drawings, the same or corresponding elements are designated by the same reference numerals, and duplicate description will be omitted as appropriate. In addition, the drawings may be partially simplified or exaggerated in order to facilitate understanding, and the dimensional ratio and the like are not limited to those described in the drawings.

In the present specification, the "building material" refers to a material that is transported and compacted to form a structure, for example, a soil material in which fine-grained material and coarse-grained material are mixed, and a cement-based material. May also be included. The "compacting information" indicates information on compaction of the compaction material, for example, the number of compactions (number of compactions), the compaction position (plane information, height information), compaction energy, and compaction. Includes surface rigidity, elevation structure rigidity, and elevation surface height. "Compacting management" means acquiring compaction information.

FIG. 1 is a diagram schematically showing a site A to which the compaction management system 1 according to the embodiment is applied. FIG. 2 is a block diagram showing the functions of the compaction management system 1 according to the embodiment. The block diagram of the compaction management system 1 is merely an example, and the function of the compaction management system 1 is not limited to the block diagram shown in FIG.

For example, at the site A shown in FIG. 1, the filling material M is transported and compacted. The erection material M is used as, for example, a central impermeable type rockfill dam, a trapezoidal CSG dam, or an RCD concrete dam. The embankment material M is, for example, transported to the embankment area D by a transport machine after being manufactured and acquiring quality information, and is used as an impermeable zone.

In the embankment area D, the embankment machine 3 spreads the embankment material M, and then the first roller 4 compacts the embankment material M by rolling the embankment material M. For example, the leveling machine 3 is a bulldozer, and the first roller 4 is a vibrating roller. Immediately after being leveled by the leveling machine 3, the building material M is in a soft state because it contains a large amount of air and moisture. However, by compacting the building material M by rolling the first roller 4 and reducing the air in the building material M, the building material M becomes in a desired density state.

The roller 4b of the first roller 4 has, for example, a substantially cylindrical shape, and a vibration device is attached to the roller 4b. The roller 4b moves on the embankment region D while receiving the vibration of the exciting device. For example, when the roller 4b moves on the embankment region D, the embankment material M in the embankment region D is compacted by the weight of the roller 4b and the longitudinal vibration of the roller 4b.

The embankment region D is, for example, divided into a plurality of compaction target regions D1 (compacting blocks) having a rectangular shape (rectangular shape as an example), and the embankment material M is sufficiently compacted for each compaction target region D1. Whether or not it is determined. In the plurality of compaction target regions D1 of the embankment region D, the first roller 4 compacts the embankment region D by rotating and compressing the embankment region D a plurality of times. The embankment area D may be further divided in the height direction (Z direction described later).

In the compaction of the embankment area D, the uneven compaction of the entire embankment area D may be repeated a plurality of times, or after the compaction of a part of the embankment area D is repeated a plurality of times, other parts of the embankment area D may be repeated. The rolling compaction in the above may be repeated a plurality of times. Each compaction target region D1 of the embankment region D has, for example, an XYZ coordinate system. For example, the X and Y directions are horizontal and intersect with each other, and the Z direction is vertical.

As shown in FIGS. 1 and 2, the compaction management system 1 includes, for example, a machine position acquisition unit 15, a control unit 20, a first roller 4, and a second roller 30 different from the first roller 4. A compaction information acquisition unit 40 and a display unit 50 are provided. The control unit 20 is provided in the server (computer or software) as an example, and communicates with each of the machine position acquisition unit 15, the first roller 4, the second roller 30, the compaction information acquisition unit 40, and the display unit 50. It is possible.

The server provided with the control unit 20 is, for example, an auxiliary composed of a processor (for example, a CPU) that executes an operating system, an application program, or the like, a main storage unit composed of a ROM, a RAM, or the like, and a hard disk, a flash memory, or the like. It includes a storage unit, a communication control unit composed of a network card or a wireless communication module, and an input device such as a keyboard or a mouse.

Each functional element of the server of the control unit 20 is realized by having a processor or a main storage unit read a predetermined software and executing the software. The processor operates the above-mentioned communication control unit and the like according to the software, and reads and writes data in the main storage unit or the auxiliary storage unit. The data or database required for server processing is stored in the main storage or auxiliary storage.

The display unit 50 includes a display of an information terminal such as a personal computer or a laptop computer, and a display of a mobile terminal such as a mobile phone or a tablet. The control unit 20 is, for example, a first roller operating unit 21 that controls the operation of the first roller 4, a second roller operating unit 22 that controls the operation of the second roller 30, and a storage unit that stores various received information. A display control unit 24 that controls the display of various information stored in the storage unit 23 on the display unit 50 is provided.

The first roller 4 is a vibrating roller that compacts the filling material M, and for example, the first roller 4 does not acquire compaction information. That is, the first roller 4 concentrates on compacting the filling material M. The second roller 30 includes a roller 31 that is smaller than the roller 4b, for example, as shown in FIG. The weight of the second roller 30 is smaller than the weight of the first roller 4. As an example, the weight of the second roller 30 is 4 tons, and the weight of the first roller 4 is 10 tons.

The first roller operating unit 21 operates the first roller 4 and compacts the filling material M by the first roller 4. The second roller operating unit 22 runs the second roller 30 on the filling material M after the compaction by the first roller 4 is completed, and acquires the compaction information of the filling material M by the second roller 30. .. That is, the second roller 30 acquires the compaction information of the filling material M that has been compacted by the first roller 4. The second roller 30 is, for example, a roller that does not perform compaction but concentrates on acquiring compaction information. In the present embodiment, the second roller 30 is a horizontal vibration roller that generates vibration in the horizontal direction, and acquires compaction information while traveling without vibration.

In the present embodiment, "vibration-free" means that vibration such as longitudinal vibration is not generated without operating the above-mentioned vibration exciting device. "Running without vibration" means running without vibration. For example, from the second roller 30 traveling without vibration, only the weight of the second roller 30 is applied to the building material M, and vibration such as longitudinal vibration is not applied to the building material M. As an example, the second roller 30 may be a nutation roller that causes vibration in the horizontal direction.

As described above, in the present embodiment, the horizontal vibrating roller (nutation roller) is used for acquiring compaction information by devoting the second roller 30, which is a horizontal vibration roller (nutation roller), to the acquisition of compaction information. It can be effectively used as a roller. For example, the second roller 30 includes an iron roller 31 and a measuring instrument that measures the deflection of the raised surface S when the roller 31 is run without vibration.

The machine position acquisition unit 15 includes a leveling machine position acquisition unit 16 that acquires the position of the leveling machine 3, a first roller position acquisition unit 17 that acquires the position of the first roller 4, and a second roller 30. A second roller position acquisition unit 18 for acquiring a position is provided. The position of the leveling machine 3 acquired by the leveling machine position acquisition unit 16, the position of the first roller 4 acquired by the first roller position acquisition unit 17, and the position of the first roller 4 acquired by the second roller position acquisition unit 18. Each of the positions of the second roller 30 is transmitted to the control unit 20 in real time, for example.

The leveling machine position acquisition unit 16 is, for example, a GNSS receiving device that receives radio waves from GNSS (Global Navigation Satellite System) and acquires the position of the leveling machine 3. In this case, the leveling machine position acquisition unit 16 includes an antenna for GNSS attached to the leveling machine 3, and when the antenna receives radio waves from the GNSS satellite, the received radio waves are demodulated. Extract information. For example, the leveling machine position acquisition unit 16 calculates the position information (latitude, longitude, etc.) of the leveling machine 3 using the received information of each GNSS satellite, and the calculated leveling machine 3 of the leveling machine 3. The position information is transmitted to the control unit 20.

Each of the first roller position acquisition unit 17 and the second roller position acquisition unit 18 may be a GNSS receiving device like the leveling machine position acquisition unit 16. In this case, each of the leveling machine position acquisition unit 16, the first roller position acquisition unit 17, and the second roller position acquisition unit 18 is the GNSS of the leveling machine 3, the first roller 4, and the second roller 30. Perform traceability.

For example, the leveling machine position acquisition unit 16 may acquire the position of the center of the track of the bulldozer, or may acquire the height position of the bulldozer. The first roller position acquisition unit 17 may acquire, for example, the position of the ground contact portion of the roller 4b with respect to the raised surface S, or may acquire the height position of the roller 4b. Similarly, the second roller position acquisition unit 18 may acquire the position of the ground contact portion of the roller 31 with respect to the raised surface S, or may acquire the height position of the roller 31.

The position information of the leveling machine 3 acquired by the leveling machine position acquisition unit 16, the position information of the first roller 4 acquired by the first roller position acquisition unit 17, and the second roller position acquisition unit 18 acquired. The position information of the two rollers 30 is transmitted to the control unit 20 in real time. It should be noted that each of the leveling machine position acquisition unit 16, the first roller position acquisition unit 17, and the second roller position acquisition unit 18 does not have to be a GNSS receiving device, and may be other equipment such as a total station or the like. May be good.

The compaction information acquisition unit 40 acquires, for example, the degree of compaction of each of the plurality of compaction target regions D1 in real time using GNSS. As an example, the compaction information acquisition unit 40 may acquire the rigidity of each compaction target region D1 from the deflection of the raised surface S of each compaction target region D1.

For example, the compaction information acquisition unit 40 divides the embankment area D into a plurality of compaction target areas D1 and acquires information on whether or not the embankment material M is sufficiently compacted for each compaction target area D1. You may. The compaction information acquisition unit 40 may calculate the amount of subsidence of the filling material M due to compaction for each compaction target area D1 and determine whether or not the filling material M has been sufficiently compacted. Hereinafter, an example of the configuration of the compaction information acquisition unit 40 will be described.

The compaction information acquisition unit 40 includes a compaction number acquisition unit 41, an upright surface shape acquisition unit 42, and an upright surface rigidity acquisition unit 43. The rolling compaction number acquisition unit 41 may calculate the rolling compaction count of the first roller 4 for each compaction target region D1 from the movement path of the first roller 4. In this case, the compaction count acquisition unit 41 may, for example, have the vertices (x1, y1), (x1, y2), (x2, y1), (x2, y2) in which the first roller 4 forms the compaction target region D1. ) Is reached once, the number of times of compaction of the compaction target area D1 may be added by 1. In this way, the compaction count acquisition unit 41 acquires the compaction count for each of the plurality of compaction target regions D1, and the compaction count acquisition unit 41 acquires the compaction count in real time to the control unit 20. Will be sent.

The raised surface shape acquiring portion 42 and the raised surface rigidity acquiring portion 43 are provided only on the second roller 30, for example, and are not provided on the first roller 4. As described above, in the present embodiment, only the second roller 30 acquires the compaction information, and the first roller 4 does not acquire the compaction information. Therefore, the first roller 4 can concentrate on compaction (rolling).

The raised surface shape acquisition unit 42 measures, for example, the three-dimensional shape data of the raised surface S in the compaction target region D1. The raised surface shape acquisition unit 42 may acquire the two-dimensional shape data of the raised surface S. For example, the shape data of the elevation surface S for each compaction target area D1 detected by the elevation surface shape acquisition unit 42 is transmitted to the control unit 20 in real time. Further, the erection surface shape acquisition unit 42 may scan the layer thickness of the erection material M in each compaction target region D1 and continuously transmit the scanned layer thickness to the control unit 20.

For example, the control unit 20 uses the number of rolling compactions received from the rolling compaction number acquisition unit 41 and the shape data of the elevation surface S received from the elevation surface shape acquisition unit 42 to fill each compaction target region D1. The height of the vertical material M (elevating surface S) may be calculated. Further, even if the control unit 20 generates a compaction management table showing the relationship between the number of compactions, the height of the erection material M, and the settlement amount (deflection) of the erection material M for each compaction target area D1. Good.

The raised surface rigidity acquisition unit 43 may be, for example, a measuring instrument that measures the deflection of the raised surface S when the second roller 30 is run without vibration. This measuring instrument is, for example, a non-contact displacement meter such as a laser displacement meter. In this case, the elevation surface rigidity acquisition unit 43 measures the amount of deflection (sinking amount) of the elevation surface S (rolling surface) due to the vehicle body load of the second roller 30 including the roller 31 (the own weight of the second roller 30). , Measure the deformation coefficient from the measured amount of deflection using Hertz's theory. This deformation coefficient is a value that correlates with the rigidity of the raised surface S. For example, if the measured deformation coefficient is high, it is found that the rigidity of the raised surface S is high, and if the measured deformation coefficient is low, the height is high. It can be seen that the rigidity of the elevation S is low. The rigidity of the elevation surface S acquired by the elevation surface rigidity acquisition unit 43 is transmitted to the control unit 20 in real time.

The control unit 20 receives the position information of the leveling machine 3, the first roller 4, and the second roller 30 received from the machine position acquisition unit 15, and the compaction material M received from the compaction information acquisition unit 40. The consolidation information is stored in the storage unit 23. The display control unit 24 controls the display of the above-mentioned information received by the control unit 20 on the display unit 50. The display control unit 24 displays, for example, a rigidity evaluation value map of the elevation surface S in each compaction target area D1 of the embankment area D on the display unit 50.

As an example, the rigidity evaluation value map of the raised surface S is a map showing the rigidity of the raised surface S for each compaction target area D1 acquired by the raised surface rigidity acquisition unit 43 together with the map. By displaying the rigidity evaluation value map on the display unit 50 in this way, the display control unit 24 can easily grasp the information regarding the homogeneity of the raised surface S. For example, the display control unit 24 may display on the display unit 50 a rolling compaction number map showing the number of rolling compactions in each compaction target area D1 of the embankment region D together with the map. Further, the control unit 20 may store compaction information of the elevation surface S including the rigidity of the elevation surface S in CIM (Construction Information Modeling).

Next, an example of each step of the compaction management method according to the present embodiment will be described with reference to FIGS. 4, 5 (a) and 5 (b). The flowchart shown in FIG. 4 is merely an example, and the content of each step of the compaction management method is appropriately changed. For example, the embankment material M for which manufacturing and quality information has been acquired is loaded on a transport machine such as a dump truck, and the embankment material M is unloaded to the embankment area D by the transport machine.

After the transport machine transports the embankment material M to the embankment area D and unloads the embankment material M, the embankment machine 3 performs the embankment material M (step T1). When the leveling machine 3 is leveling the embankment material M in the embankment area D, the position of the leveling machine 3 in the embankment area D is acquired by the leveling machine position acquisition unit 16.

After the leveling of the building material M by the leveling machine 3 is completed, the first roller 4 compacts (compacts) the building material M as shown in FIG. 5 (a). Hardening step X1, step T2). At this time, the first roller operating unit 21 may operate the first roller 4. When the first roller 4 is compacting the embankment material M in the embankment area D, the position of the first roller 4 in the embankment area D is acquired by the first roller position acquisition unit 17.

For example, the compaction number acquisition unit 41 acquires the compaction number of each compaction target region D1 from the movement path of the first roller 4 obtained by the first roller position acquisition unit 17 (step T3). At this stage, the first roller 4 only compacts (rolls) the compaction target area D1, and the second roller 30 that acquires compaction information does not operate.

After the above rolling compaction and acquisition of the number of rolling compactions, it is determined whether or not the compaction (predetermined rolling compaction) of the embankment region D by the first roller 4 is completed (step T4). Then, when it is determined that the compaction of the embankment area D is not completed, the process returns to step T2 to perform compaction and acquisition of the number of compactions again. For example, the completion of compaction (predetermined compaction) is determined by the control unit 20, and at this time, compaction completion position information may be generated. This compaction completion position information is stored in, for example, the storage unit 23.

When it is determined in step T4 that the compaction of the embankment area D is completed, for example, the second roller 30 compacts the embankment area D based on the compaction completion position information stored in the storage unit 23. Acquire information (compacting management) (step X2 of acquiring compaction information). As a specific example, the first roller 4 that has compacted the embankment region D goes out of the embankment region D, and as shown in FIG. 5B, the first roller 4 is the target for acquiring the compaction information of the embankment region D. 2 Roller 30 acquires compaction information. At this time, for example, the second roller operating unit 22 operates the second roller 30. It is also possible to control the operation of the second roller 30 by the second roller operating unit 22, that is, to automatically operate the second roller 30, according to the rolling compaction completion position information stored in the storage unit 23. In this case, It is possible to save labor in the process of acquiring compaction information associated with the quality information of the embankment.

For example, the second roller 30 does not compact the embankment area D. In the second roller 30, the elevation surface shape acquisition unit 42 acquires the shape of the elevation surface S in each compaction target area D1 as two-dimensional data or three-dimensional data, and the elevation surface rigidity acquisition unit 43 acquires each compaction. Acquire the rigidity of the raised surface S of the target region D1 (step T5).

Then, from the compaction information including the shape of the embankment surface S and the rigidity of the embankment surface S obtained in step T5, it is determined whether or not the compaction state of the embankment region D satisfies a predetermined quality ( In step T6), if it is determined that the predetermined quality is not satisfied, for example, rolling compaction or the like is executed again, or necessary measures are taken to satisfy the predetermined quality. On the other hand, if it is determined in step T6 that the predetermined quality is satisfied, a series of steps is completed.

Subsequently, the compaction management method and the operation and effect obtained from the compaction management system 1 according to the present embodiment will be described in detail. In the compaction management method according to the present embodiment, first, the first roller 4, which is a vibrating roller, compacts the filling material M. Then, after the compaction of the filling material M by the first roller 4 is completed, the second roller 30 different from the first roller 4 runs on the filling material M to acquire the compaction information. Therefore, the first roller 4 compacts the filling material M, and the second roller 30, which is different from the first roller 4, acquires compaction information, so that the first roller 4 concentrates on compaction, and the first roller 4 concentrates on compaction. The 2 roller 30 can concentrate on the acquisition of compaction information.

Therefore, the first roller 4 concentrates on compaction and the second roller 30 concentrates on acquiring compaction information, so that the first roller 4 that compacts the filling material M acquires a huge amount of compaction management data. The second roller 30 can be sufficient to acquire the minimum necessary compaction information by devoting itself to compaction management. That is, since the second roller 30 does not need to be compacted and can perform sufficient quality control by acquiring the minimum necessary compaction information, it is necessary to acquire a huge amount of data and to obtain a huge amount of data. Data extraction is not required.

Therefore, since the time required for data acquisition and the like can be reduced by performing the compaction management by the second roller 30 after the first roller 4 has compacted, the compaction and compaction management can be efficiently performed. It can be carried out. That is, by performing the compaction step X1 and the compaction information acquisition step X2 in series, it is possible to concentrate on compaction and eliminate the need for acquisition of a huge amount of data, so that compaction and compaction can be performed. Management can be performed efficiently. Further, since the second roller 30 concentrates on the compaction management, the influence of the filling material M on the compaction state at the time of the compaction management can be suppressed, so that the quality of the compaction can be improved.

In the present embodiment, the second roller 30 acquires compaction information while traveling without vibration. In this way, when the second roller 30 acquires compaction information while traveling without vibration, the second roller 30 does not compact the filling material M, so that the filling material M is brought into the compacted state. The impact can be suppressed more reliably. Therefore, the quality of compaction can be further improved.

In the present embodiment, the second roller 30 is a horizontal vibration roller that generates vibration in the horizontal direction. Therefore, the horizontal vibrating roller that generates vibration in the horizontal direction can be effectively used as the second roller 30 for compaction management. The horizontal vibrating roller is used for the purpose of repairing irregularities or fine cracks generated on the embankment surface by the vertical vibrating roller. In general, the vertical vibrating roller reciprocates the embankment surface a plurality of times to perform the compaction work, whereas the horizontal vibrating roller performs the above-mentioned repair work by moving once or twice. Therefore, the horizontal vibrating roller has a lower operating rate than the vertical vibrating roller and is often not in operation. Therefore, the horizontal vibrating roller can be effectively used as a compaction management application for acquiring compaction information. it can.

In the present embodiment, the weight of the second roller 30 is smaller than the weight of the first roller 4. Therefore, since the weight of the second roller 30 is small, it is possible to more efficiently manage the running and compaction of the second roller 30 on the building material M.

In the compaction management system 1 according to the present embodiment, the first roller operating unit 21 operates the first roller 4, which is a vibrating roller, to compact the filling material M, and the compaction of the filling material M is completed. After that, the second roller operating unit 22 operates the second roller 30, which is different from the first roller 4, to acquire compaction information. Therefore, as in the compaction management method according to the present embodiment, the first roller 4 compacts the filling material M, and the second roller 30 acquires the compaction information to acquire a huge amount of compaction data. It is possible to efficiently perform compaction and compaction management, and to improve the quality of compaction.

Further, each of the first roller operating unit 21 and the second roller operating unit 22 operates the first roller 4 and the second roller 30, thereby compacting the filling material M by the first roller 4 and the first roller.
