Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a slope excavation management system 10 according to the present invention.

In FIG. 1, this slope excavation management system 10 comprises a sensor 11 arranged on the slope during excavation, and a three-dimensional positioning device 12 for determining the position of this sensor 11. In addition, based on the position of the sensor 11 obtained by the three-dimensional positioning device 12 and the information of the design excavation line that has been input in advance, a computer 13 that analyzes various data necessary for excavation management, and the excavation site.

In the excavation management system 10 on the slope, the three-dimensional position determining device 12 is installed at a known point whose coordinate value is obtained by triangulation or the like. The three-dimensional positioning device 12 emits a light wave toward the sensor 11. Then, the sensor 11 installed at the excavation site reflects this light wave to the three-dimensional positioning device 12. The reflected light reflected by the sensor 11 is sensed by the three-dimensional positioning device 12,
In the three-dimensional positioning device 12, the coordinates of the current position of the sensor 11 are obtained based on the coordinate value of the known point where the three-dimensional positioning device 12 is installed and the reflected light.

As such a three-dimensional position determining device 12, a known light wave detector, for example, Geosimeter 140T type manufactured by Geosimeter Co., Ltd. can be used. As the sensor 11, a reflecting prism that reflects the light wave emitted from the three-dimensional positioning device can be used. As shown in FIG. 2, the sensor 11 is provided at one end of the rod-shaped member 20, and the operator excavates the sensor 11 by moving the rod-shaped member 20 provided with the sensor 11 at the excavation site. It is possible to move freely on site. Further, since the sensor 11 is provided at the tip of the rod-shaped member, it is possible to see through the sensor 11 even in the concave portion on the ground surface.

The computer 13 comprises a memory 15,
Information on the design excavation line to be excavated is input to the memory 15 in advance. Further, this computer 13 is connected to the three-dimensional positioning device 12, and based on the current location of the sensor 11 input from the three-dimensional positioning device 12 and the information of the design excavation line previously input to the memory 15, Information required for excavation management of slopes, such as slope of slopes, drilling length, and the relationship between any point on the design excavation line and the current location of the sensor, can be output numerically or on a screen. It is configured.

In the excavation management system 10 according to the present invention, the remote controller 14 as the output means operates the remote controller 14 from the three-dimensional positioning device 12 and the computer 13, for example, from the excavation site, to the three-dimensional positioning device 12 and the computer 13. It is possible to read the data and various data.

The remote controller 14 has a display screen such as a liquid crystal display or a CRT, and can display the relationship between the position of the sensor 11 and the design excavation line as a plan view, a dam axial direction sectional view, and a joint direction sectional view. As a result, the operator at the excavation site can know the current location of the sensor from the plan view, the drilling length and excess excavation amount from the dam axial sectional view, and the shape of the slope in the joint direction from the joint direction sectional view.

Next, an outline of the slope excavation management method according to the present invention will be described with reference to FIG. Information on the design excavation line to be excavated is input to the memory 15 of the computer 13 in advance (step 101).

The three-dimensional positioning device 12 emits a light wave to the sensor 11 at the excavation site, and the sensor 11 reflects this light wave.
The three-dimensional positioning device 12 receives the reflected light from the sensor 11, and detects the position of the sensor 11 based on the received reflected light and the coordinates of the known point where the three-dimensional positioning device 12 is installed ( Step 102).

The position of the sensor 11 detected by the three-dimensional positioning device 12 is input to the computer 13 (step 103). The computer 13 analyzes various data required for excavation management based on the information of the design excavation line previously input to the memory 15 and the position of the sensor 11 input from the three-dimensional positioning device 12 ( Step 1
04).

The data analyzed by the computer 13 is output to the remote controller 14 at the excavation site (step 105). The operator performs various operations based on this data.

The slope excavation management method of the present invention will be described below in accordance with an actual slope excavation method. 4 and 5 are views for explaining the excavation management method for the slope according to the present invention.

4 and 5, the design excavation line AA '
Shows a cross section of a slope for excavation according to the present invention. The design excavation line AA ′ has a first change point 41, a second change point 42,
It is assumed that there is a bend at the third change point 43, and the change points 41, 42, and 43 are connected by a straight line.

Further, in FIG. 4, the first change point 4 has already been reached.
The excavation up to 1 has been completed, and hereinafter, the slope 44 between the first change point 41 and the second change point 42 is to be excavated. Further, the three-dimensional positioning device 12 is installed at a known point 45 through which these changing points 41, 42, 43 can be seen.

In the excavation control method for the bending slope, first, a hole is drilled at a predetermined position B1 on the ground surface B, and a dynamite is set in this hole to explode. At this time, in the excavation management method for the bending slope of the present invention, by inserting the sensor 11 into the drilled hole, the drilled hole length and the designed drilling line AA '.
It is possible to display the relationship with the as a sectional view in the axial direction of the dam on the remote controller 14 at the excavation site.

In this respect, according to the conventional method, the drilling is performed based on the calculation at the excavation site or the operator's intuition. On the other hand, according to the slope excavation management method of the present invention, it is possible to perform the bombing after grasping the relationship between the drilling hole and the design excavation line at the excavation site. Therefore,
It is possible to perform blasting up to near the design digging line and reduce the amount of digging for finishing by the hydraulic breaker that is performed next time, so it is possible to speed up the work.

When the drilling has not reached the predetermined depth, further drilling is performed to deepen the drilling. A new ground surface C is formed by this blast.

Thereafter, the first change point 41 to the second change point 4
The excavation of the slope 44 is done with a hydraulic breaker towards 2. At this time, in the excavation management method of the present invention, the information required for excavation by the hydraulic breaker, such as the slope of the slope to be excavated, the excavation length, and the surrounding shape prediction, can be displayed on the remote controller 14 at the excavation site. Since the operator can perform the work based on this information, the work efficiency can be improved.

According to the slope excavation management method of the present invention, the slope 44 is formed on the remote controller 14 at the site.
The inclination indicating the inclination of the slope 44 is not necessarily required because the inclination of the slope can be displayed. Therefore, it is possible to shorten the time required for installing the strut. However, if the tension is installed at an arbitrary position on the first change point 41 or the slope 44, more reliable work can be performed.

When it is difficult to excavate up to the second change point 42 by the hydraulic breaker with only one blast,
Again, a hole is drilled at a predetermined position C1 on the ground surface C, and dynamite is set in this hole to explode. This blast creates a new ground surface.

Then, based on the data output to the remote controller 14 again, the excavation of the slope 44 is performed by the hydraulic breaker toward the second change point 42.
Hereinafter, the blasting with the dynamite and the finishing excavation with the hydraulic breaker are repeated as many times as necessary until the excavation slope 44 reaches the second change point 42.

Looking at the time when the excavated slope 44 reaches the second change point 42, the worker moves on the slope 44 with the sensor 11 and the remote controller 14 and moves to the second change point 42. Detect. At this time, according to the present invention, the relationship between the current position of the sensor 11 and the second change point 42 is expressed as a numerical difference in coordinate values, or as a plan view, a dam axial direction sectional view, and a joint direction sectional view at the excavation site. Since it is displayed on the remote controller 14, it becomes possible to detect the second change point 42 efficiently.

The sensor 11 is also provided on the excavated slope 44.
It is possible to confirm whether or not the slope 44 is finished according to the design excavation line by moving the.

As a result of the detection by the present invention, as shown in FIG. 5, when it is determined that there is an uncut portion 48 on the slope, the excavation of the slope 44 in the inclination direction is further continued. Then, the excavation by the hydraulic breaker and the detection of the second change point 42 using the excavation management system on the slope are repeated until the finish excavation reaches the second change point 42.

With respect to this point, according to the conventional method, when it is necessary to detect the second change point 42 and to confirm the working condition such as the presence or absence of the uncut portion 48 of the slope 44, it is necessary to leave the slope. At the machine point, the observer had to collimate using the tachometer. In contrast, according to the present invention, once the three-dimensional positioning device 12 is installed at the known point, the sensor 11 and the remote controller 14 are provided on the slope 44 where the worker is excavated.
By moving while holding, it is possible to detect the second change point 42 and confirm the presence or absence of the uncut portion 48 of the slope 44.

When the excavation ends up to the second change point 42, the slope 46 between the second change point 42 and the third change point 43 is excavated by the same method. It should be noted that the present invention is not limited to the above-described embodiments, and can be modified as appropriate. For example, although the excavation management system and the excavation management method on the slope in the dam construction have been described in the above-mentioned embodiments, the present invention is not limited to this, and the disposal site construction, the residential land development construction, and other cutting It can also be used for embankment work.

Further, in the above-described embodiment, the position of the sensor 11 on the slope 44 during excavation is determined by the three-dimensional positioning device 12 installed at the known point 45, but the present invention is not limited to this. It is not limited, for example,
As a three-dimensional positioning device, the Global Positioning System (GP
It is also possible to use satellite geodetic systems such as S).
