A compaction surface 2a is formed on the surface of the embankment 2 as a compaction surface for the compaction device 3 in a substantially square shape in FIG. In the embankment construction area 1, a large number of measurement points Pn are respectively set on the rolling surface 2a in the form of predetermined coordinate positions (Xn, Yn) with respect to a reference position P0 arbitrarily set on the rolling surface 2a. Has been done,

It is arranged at an arbitrary current position (Xn, Yn) on the Y coordinate. It should be noted that the GPS antenna 7 can detect the coordinate position where each rolling compaction device 3 is arranged in a three-dimensional manner by the X, Y, and Z axes. Only the coordinate position is specified.

As shown in FIG. 2, each compaction device 3 has a vehicle body 5 of a tire roller vehicle for embankment compaction,
At the lower part of the vehicle body 5, as wheels capable of rolling over the embankment 2, there are front wheels 6A and rear wheels 6B paired in the left-right direction in FIG. 2, one pair each in the direction intersecting the plane of FIG. 2 (that is, four wheels). ),
The rolling surface is provided so as to be freely driven to roll. A GPS antenna 7 is provided on the rear portion of the vehicle body 5 shown on the right side of FIG. 2 with its receiving portion 7a facing the sky side shown on the upper side of FIG. In order to detect the current position, the compaction device 3 receives a radio wave S2 from a surveying orbit satellite (not shown), and thereby identifies the coordinate position (Xn, Yn) of the compaction device 3 with respect to the reference position P0. In this way, a position detecting means that can grasp the current position of the vehicle body 5 is configured together with a GPS control device 21 described later. On the front side of the GPS antenna 7 shown on the left side of FIG. 2, a communication antenna 9 is communicable between the respective compaction devices 3 arranged in the embankment construction area 1 as described above. A display panel 10 provided on the front side of the communication antenna 9 and capable of displaying the rolling condition on its screen is arranged here in a form that can be read by an operator sitting on the seat 51 of the vehicle body 5. It is set up.

In the lower part of the vehicle body 5 near the center in the front-rear direction shown in the left-right direction of FIG. 2 of the compaction device 3, a scatter type RI meter 11 using a radioisotope is compacted by the compaction device 3. In a form that can detect the density ρ and the water content W of the existing embankment 2,

It is mounted on a vehicle body 5 that travels by 6A and rear wheels 6B. The RI meter 11 causes the detector tube 11b to detect scattered waves of radiation oscillated from the compaction surface 2a into the embankment 2 by the radioisotope source 11a, and counts the scattered waves of the radiation ρ and Since this is a known densitometer configured to detect the water content W, detailed description thereof will be omitted. An approach sensor 12 is provided at the rear end portion of the vehicle body 5 shown on the right side of FIG.
The object to be detected behind is attached to the proximity sensor 12 in such a manner that it can be detected at a predetermined distance from the position of the proximity sensor 12.

Further, as shown in FIG. 2, the compaction device 3 has a first distance sensor 13 located in front of the front wheel 6A.
A and a second distance sensor 1 located behind the rear wheel 6B.
3B are provided so as to be respectively located in the lower portion of the vehicle body 5, and the first distance sensor 13A and the second distance sensor 1 are provided.
3B is a distance between each of them and the rolling surface 2a by utilizing infrared rays, ultrasonic waves, electromagnetic waves, etc., that is, the distance sensor 1
Heights h1 and h from the rolling surface 2a where 3A and 13B are located
2 can be detected respectively. Further, on the upper part of the vehicle body 5 of the compaction device 3, compaction management is performed based on the information obtained from the GPS antenna 7, the communication antenna 9, the RI meter 11, the first distance sensor 13A, the second distance sensor 13B, and the like. A system control device 15 for carrying out is stored.

The system controller 15 has a main controller 16 as shown in FIG. 3, and the main controller 16 includes a first distance sensor controller 19 and a second distance sensor controller 19 via a data input interface 17. The distance sensor control unit 20, GPS control device 21, communication control device 22, RI meter control communication unit 23, manual input unit 27, etc. are connected. First distance sensor control unit 1
9, the first distance sensor 13A is connected to the second distance sensor control unit 20, the second distance sensor 13B is connected to the second distance sensor control unit 20, the GPS antenna 7 is connected to the GPS control device 21, and the communication control device 22 is connected to the communication control device 22. Communication antenna 9 is RI
The RI meter 11 is connected to the meter control communication unit 23. Further, the main control unit 16 is connected to a calculation unit 25, a display control unit 26, etc., the calculation unit 25 has a compaction data memory 24, and the display control unit 26 has the display panel 1 described above.
0 is connected. Therefore, the calculation unit 25 of the system control device 15 uses the distance h1 between the rolling surface 2a detected by the first distance sensor 13A and the second distance sensor 13B in front of and behind the front wheels 6A and 6B, respectively. h
From the difference of 2 (h2-h1), the rolling compaction amount hZn of the embankment 2 compacted by the vehicle body 5 of the compacting device 3 can be calculated and calculated, and the rolling compaction amount calculating means is configured. ,Also,
The display panel 10 is configured to form an output means so as to be able to output the rolling amount data DAT such as the rolling amount hZn calculated by the calculation unit 25. The compaction data memory 24 stores the current position (Xn, Yn) of the vehicle body 5 detected by the GPS control device 21 by the GPS antenna 7 and the embankment 2 compacted here, as described above.
As shown in FIG. 6, the rolling pressure amount hZn of the measurement point P
The storage means in the compaction device 3 is configured so that it can be stored as the compaction amount data DAT for each n.

Since the embankment construction area 1 and the compaction device 3 have the above-mentioned constitutions, when the embankment construction of the embankment construction area 1 is performed, the ground leveling 3 formed by grounding the base 39 is formed.
A predetermined amount of embankment is applied on 9a, and the surface thereof is spread and leveled to form the compacted surface 2a. At such a place, the front wheel 6A and the rear wheel 6B are controlled using the compaction device 3 according to the procedure FLO shown in FIG.
Rolling on the rolling surface 2a to compact the embankment 2 through the weight of the vehicle body 5 so that the finished thickness of the embankment 2 is approximately D1. Go. Therefore, first, in each of the compaction devices 3, as shown in FIG.
In step ST1, the compaction specifications such as the compaction frequency, compaction range, layer thickness (that is, the value of finish thickness D1), compaction speed, compaction standard, and the like are input from the manual input unit 27, and such compaction is performed. The specifications are stored in the compaction data memory 24. At this time, the compaction data memory 24 uses the total compaction amount hZT required to reach the finish thickness D1 as a compaction standard.
Alternatively, the value of the surface layer density ρ required for the embankment 2 after the completion of the compaction is stored as a reference value.

Thus, the rolling operation is started in step ST2 of FIG. Therefore, the system control device 1 is configured to issue the measurement start command S1 via the manual input unit 27.
The main controller 16 of No. 5 starts the operation of each measuring instrument of the compaction device 3. In this case, first, step ST3 in FIG.
As shown in, the compaction device 3 is made to grasp the GPS start position. Therefore, the main control unit 16 first determines the GPS antenna 7
The radio wave S2 from the orbiting satellite for surveying is received by the GPS control device 21 and the current position of the compaction device 3 is detected by the GPS control device 21 based on the radio wave S2. Then, the current position of the compacting device 3, that is, the coordinate position (X
(n, Yn) are stored in the compaction data memory 24. Thus, as shown in step ST4 of FIG. 4, measurement of the current position of the compaction device 3, measurement of h2-h1 (that is, compaction amount hZn), measurement of density (ρ), measurement of water content (W), etc. By detecting the degree of compaction of the embankment 2 and running the compacted vehicle body 3 on the compaction surface 2a, the compacted soil 2 is compacted through the weight of the front wheels 6A and the rear wheels 6B. Perform rolling work.

Therefore, the system controller 1 of the compaction device 3
5, the main control unit 16 causes the GPS control device 21 to sequentially detect the current position of the compaction device 3 by the radio wave S2 received by the GPS antenna 7. Then, each time the compaction device 3 is located at the measurement point Pn, the first distance sensor control unit 1
9, second distance sensor control unit 20, RI meter control communication unit 23
First distance sensor 13A, second distance sensor 13B, R
The I meter 11 measures the amount of compaction hZn, the density ρ, and the amount of water W. That is, the embankment 2 is the vehicle body 5 of the compaction device 3.
In the form of being compacted by a predetermined height by the weight of the vehicle body 5 through its front wheels 6A and rear wheels 6B,
The height of the compaction surface 2a from the ground surface 39a is reduced, and along with this, the soil particles forming the embankment 2 are compacted, and the value of the density ρ is increased. Then, the water content W changes as the density ρ changes. Therefore, at the measurement point Pn, the system control device 15 firstly outputs the first distance sensors 13A provided before and after the front wheels 6A and the rear wheels 6B, respectively.
By using the second distance sensor 3B, the compaction device 3
Then, the rolling compaction amount hZn of the embankment 2 compacted by the passage of is calculated. That is, the main control unit 16 includes the first distance sensor control unit 19 and the second distance sensor control unit 20 by the first distance sensor 13A and the second distance sensor 13B, respectively.
The distances h1 and h2 from a are detected respectively. And
The data input interface 17 uses the values of h1 and h2.
To the calculation unit 25 via the. Then, the arithmetic unit 25 that receives this calculates the difference (h2-h1) between the h1 and h2 as
It is calculated and calculated as a rolling pressure amount hZn. Therefore, the main controller 1
Reference numeral 6 indicates to the calculator 25 the coordinate position (Xn, Yn) of the measurement point Pn where the compaction device 3 was located when the compaction amount hZn was calculated, and the value of the compaction amount hZn. As the quantity data DAT, as shown in FIG.
4 to store. Then, the main control unit 16 updates the value of the rolling compaction amount hZn in the rolling compaction amount data DAT for each measurement at the measurement point Pn, and causes the arithmetic unit 25 to:
By accumulating the rolling compaction amount hZn for each measurement, the total rolling compaction amount hZT indicating the total sum of the rolling compaction amounts hZn at the measurement points Pn, that is, how much the embankment 2 is compacted at the measurement points Pn. Is stored in the compaction data memory 24 as compaction amount data DAT.

For example, as shown in FIGS. 5 (a) to 5 (c), when the compaction device 3 passes a predetermined measurement point P1 three times, the compaction device 3 passes the measurement point P1. The rolling pressure amount hZn is calculated each time. Therefore, if the rolling compaction amount hZn is accumulated, the rolling compactor 3 measures the measurement point P1.
The total rolling amount hZT of the embankment 2 that has been compacted is obtained by passing through 3 times. That is, at the measurement point P1, the value of the amount of compaction due to the first compaction shown in FIG. 5A is hZ1 (= h2-h1), and the compaction due to the second compaction shown in FIG. The value of the quantity is hZ2, which is 3 shown in FIG.
When the value of the amount of compaction by the second compaction is hZ3, the total amount of compaction is calculated by hZT = hZ1 + hZ2 + hZ3. Therefore, as shown in FIG. 5 (a), the embankment 2 whose rolling surface 2a is formed so as to form a predetermined layer thickness Dn from the leveled ground 39a has the rolling rolling shown in FIGS. 5 (a) to 5 (c). In the form compacted by the height hZT, the compaction is completed so that the layer thickness Dn is substantially (H1-hZT = D1). Therefore, the compaction data memory 24 shown in FIG.
In the rolling amount data DAT, the value of the rolling amount hZn is hZ1 every time the rolling device 3 passes the measurement point P1.
From hZ2 to hZ3. Also,
The value of the total rolling amount hZT of the rolling amount data DAT is cumulatively updated every time the rolling device 3 passes the measurement point P1.
By the way, as shown in FIGS. 5A to 5C at a certain measurement point P1, the embankment 2 pressed three times has a density ρ value of the embankment 2 at the measurement point P1 of ρ1 <ρ.
It increases so that 2 <ρ3.

Therefore, the system controller 15 measures the density ρ and the water content W at the same time as calculating the rolling compaction amount hZn as described above at each measurement point Pn. That is,
The main control unit 16 causes the RI meter control communication unit 23 to contact the rolling surface 2a by causing the radiation source 11a and the detection unit 11b of the RI meter 11 to project downward, and in this state, embankment at the measurement point Pn. The density ρ of 2 and the water content W are detected. Then, the values of the detected density ρ and water content W are calculated 25 via the data input interface 17.
To be transmitted. Then, the calculation unit 25 which received this has the values of the density ρ and the water content W in correspondence with the coordinate position (Xn, Yn) of the measurement point Pn, the rolling compaction amount hZn, and the total rolling compaction amount hZT. As shown in FIG. 6, the rolling amount data DAT is stored in the rolling data memory 24. In this manner, the compaction device 3 compacts the embankment 2 while measuring the compaction amount hZn, the density ρ, and the moisture content W at each measurement point Pn at each measurement point Pn, as shown in step ST5 of FIG. While these measured result values are stored and updated in the compaction data memory 24 via the calculation unit 25, the measurements are performed while compacting while moving to different measurement points Pn one after another. Go. Then, such rolling pressure hZ
n, total rolling pressure hZT, density ρ, water content W, and other measurement result values directly represent the rolling compaction finish state of the embankment 2 during rolling, so the rolling compaction is performed in real time. The finishing state can be detected. In addition, embankment construction area 1
Is provided with a plurality of compaction devices 3, and each of the compaction devices 3 has a communication antenna 9 which communicates measurement values for each measurement point Pn. The measured values measured by the plurality of compaction devices 3 are stored in the compaction data memory 24 of each compaction device 3. Therefore, during the rolling operation, the main control unit 16 uses the display control unit 26 to measure the rolling pressure amount data DAT such as the total rolling pressure amount hZT, the density ρ, and the water amount W obtained by the measurement. Each measuring point P where the compaction device 3 was located at
A three-dimensional display is made on the display panel 10 in a form corresponding to the coordinate position (Xn, Yn) of n. The value on the display panel 10 is updated every time the arithmetic unit 25 updates each value of the rolling pressure amount data DAT in the rolling pressure data memory 24. Then, the operator on the seat 51 driving the vehicle body 5 of the rolling compaction device 3 confirms the rolling compaction amount data DAT for each of the measurement points Pn as the embankment finish state in a pull-flooring-like manner while checking the rolling compaction surface. 2a
Since the car body 5 can be run on the above, as a result,
It is possible to accurately reflect the measured value in the compaction work. It should be noted that some of the rolling compaction devices 3 that are rolling compaction in the embankment construction area 1 have an approach sensor 12 attached to each vehicle body 5.
From the place where the
The collision accident of the compaction device 3 is prevented even while visually observing.

In this way, the compaction device 3 operates in step S in FIG.
As shown by T6, the compaction work is continued while performing the above-described measurement until compaction is completed at all the measurement points Pn. That is, while the compaction device 3 is performing compaction work while detecting the embankment finish state as described above, the main controller 16 of the system controller 15 causes the calculator 25 to operate the compaction data memory 24. Rolling compaction amount data DA
As described above, the rolling compaction amount hZn, the density ρ, and the water content W at each measurement point Pn of T are set to the reference values input from the manual input unit 27 as the rolling compaction specifications in the embankment 2 in the embankment construction area 1. Whether or not it has been reached is determined, and the rolling operation is performed until the reference value is reached. Then, when the rolling compaction is completed, the main control unit 16 causes the calculating unit 25 to perform the total rolling operation of the cumulative total stored in the compacting data memory 25 during the compacting work as described above in step ST7 of FIG. Pressure hZ
The finish layer thickness Dn of the embankment 2 is calculated by T. Then, the embankment 2 is finished so that the total rolling amount hZT at each measurement point Pn reaches the reference value, and thus the finish layer thickness Dn is roll-finished so as to be substantially D1. ing. Therefore, based on the calculated finish layer thickness Dn, the calculation unit 25 is made to calculate the finished shape of the embankment construction area 1 as shown in step ST8 of FIG. At this time, since the finishing layer thickness Dn (= D1) at each measurement point Pn has already been calculated,
The finished shape can be easily calculated without the need to measure the layer thickness of the embankment 2 again. In this way, in the embankment construction area 1, by using the compaction device 3, it is possible to perform the compaction work of the embankment 2 while detecting the embankment finish state in real time. The various measurement results performed on the
As AT, it can be immediately fed back to the compaction work, and thereby an efficient and accurate compacted embankment can be formed. Therefore, if a dam, a road or the like is constructed by using the embankment 2 thus constructed accurately, a high quality structure can be completed.

In the embodiment described above, the RI meter 11 is provided at the bottom of the vehicle body 5 of the compaction device 3 so that the radiation source 11a and the detector 11b thereof can be projected and retracted so as to come into contact with the compaction surface 2a of the embankment 2. The example in which the density ρ and the water content W at the measurement point Pn are measured and detected by the RI meter 11 has been described above, but the first object of the present invention is to measure the rolling pressure amount hZn for each measurement point Pn. It is detection, and therefore, an instrument for detecting the density ρ and the water content W may be provided separately from the compaction device 3. In addition, in the embodiment, the compaction device 3 is provided with a position detecting means composed of the GPS antenna 7 and the GPS control device 21, and the position detecting means is used to coordinate the current position of the vehicle body 5 ( Xn, Yn) has been described as an example. However, the position detecting means for detecting the current position of the vehicle body 5 may have any other structure. Alternatively, the compaction device 3 and the position detection means may be separate bodies, that is, there may be a compaction device 3 without the position detection means. Further, in the above-described embodiment, the rolling pressure amount hZn measured at each measurement point Pn and the rolling pressure amount h.
Total rolling pressure hZT calculated by accumulating Zn
And the density ρ and the water content W are stored in the rolling compaction data memory 24 as the compaction compaction amount data DAT.
The example in which the rolling compaction device 3 is configured so that each value of the rolling compaction amount data DAT can be three-dimensionally output for each measurement point Pn is described in 0. The storage format of the rolling amount data DAT and the output format of the display panel 10 are arbitrary. Therefore, in the rolling amount data DAT that is finally output to the display panel 10 in the rolling device 3, the value of the rolling amount hZn is output once each time the vehicle body 5 passes the measurement point Pn. But it doesn't matter. Alternatively, only the value of the total rolling pressure amount hZT may be updated and output at all times without outputting the value of the rolling pressure amount hZn once. With any of these output methods, the operator on the seat 51 can sufficiently grasp the rolling condition. Further, in the above-described embodiment, the compaction device 3
Although the rolled platen to be rolled by using the above is the embankment 2, the rolled platen is not limited to such a plate-shaped embankment 2.

[0019]

As described above, according to the present invention, the vehicle body 5 is provided, and the wheels such as the front wheels 6A and the rear wheels 6B that can roll the platen to be rolled such as the embankment 2 are rolled on the vehicle body 5. A plurality of flexible shapes are provided, and the distances h1 and h from front and rear sides of the wheels of the vehicle body 5 to the rolling surface such as the rolling surface 2a of the rolling platen.

A calculation capable of calculating the rolling pressure amount hZn of the rolled platen that is rolled by the wheel from the difference h2-h1 between the distances h1 and h2 between the rolling surface 3A and the rolled surface that are detected by the second distance sensor 13B. The rolling device is provided with a rolling amount calculating means such as the section 25, and with an output means such as the display panel 10 capable of outputting the rolling amount hZn of the rolling plate calculated and calculated by the rolling amount calculating means. Since the rolling device such as No. 3 is configured, the rolling platen is rolled by rolling the wheels with respect to the rolling surface, but during the rolling operation, the first distance sensor 13A and the second distance sensor 13B. Based on the difference h2-h1 between the distances h1 and h2 between the rolling surface 2a and the rolling surface 2a, the rolling amount calculation means calculates the rolling pressure amount hZn of the rolling platen, and the calculated rolling pressure amount hZn. Can be sequentially output to the output means 10. That is, in front of the wheel, the first distance sensor 1
The difference h2-h1 between the distance h1 detected by 3A and the distance h2 detected by the second distance sensor 13B behind the wheel is
Generated by the rolling device rolling the platen to be rolled,
It is equivalent to the rolling pressure amount hZn of the rolled platen. Therefore, while performing the rolling operation using the rolling device, the rolling operator operating the vehicle body 5 by sequentially outputting the rolling compaction amount hZn as described above to the output means provided in the vehicle body 5. Is
It is possible to immediately grasp and confirm the rolling pressure amount hZn of the rolling platen currently rolling. Thus, according to the present invention, it is possible to detect the rolling finish state in real time while performing the rolling work. Therefore, if the present invention is used for embankment construction when constructing roads, dams, etc. By using the rolling compaction amount hZn detected in real time, it is possible to proceed the rolling compaction work while always checking the embankment finish state. Therefore, it is possible to proceed with the compaction work while always quickly responding to the value of the compaction amount hZn, and therefore it is possible to perform embankment construction with accurate specifications. As a result, a high quality embankment can be made. Further, according to the present invention, it is not necessary to perform the measurement for quality control separately from the compacting work, and to wait for the result to be detected to make a correction, which is efficient. Further, when the rolling compaction amount hZn is detected, the rolling compaction amount hZn
Since the compacted embankment thickness Dn can be easily calculated using, the quality control relating to the construction is easy.

Further, in the present invention, the GPS antennas 7 and G capable of grasping the current position (Xn, Yn) of the vehicle body 5
