Description

[0001]
BACKGROUND OF THE INVENTION
TECHNICAL FIELD The present invention relates to a soil height management method for grasping and managing the height of a solidified soil or sand slurry placed on land or when the soil having a natural water content is sprinkled.
[0002]
[Prior art]
Conventionally, when placing solidified soil and soil, or performing landfill work by expelling soil with a natural water content ratio, construction management at the height when placing or expelling in the water or in the air is performed. Must be done.
[0003]
For such construction management at the time of placing in water or in the air, height management by auto red is adopted, and the construction management is point management by pinpoint.
[0004]
That is, there is known a compact and easy-to-handle water depth measuring device (see, for example, Patent Document 1) that measures the water depth by lowering the weight to the bottom of the water and detecting the feeding length of the wire when the weight reaches the bottom. ing.

JP 2002-48539 A [0006]
In such a conventional technique, since the height can be managed only at the point, the planar surface cannot be managed centering on the placement or striking location, so the location of the placement or striking location Along with the shape, it is difficult to grasp the shape of places that have already been placed or squeezed out, and surveying these places has taken the time of surveying and has the problem of poor surveying efficiency. .
[0007]
[Problems to be solved by the invention]
In the present invention, when placing or setting out the earthing device by moving the placing or setting device every predetermined position, or when setting up the earth and sand, the measuring direction of the laser profiler is rotated by 180 degrees or more, and The data of the circular surface can be acquired in a plane centering on the struck area, and the shape of the place where the placement has already been done or finished has been grasped. The impact of the inflow and the collapse of the earth and sand can be grasped, and when confirming the finished mold at the place where the placement or the pouring is finished, it is almost the same as the arbitrary direction in which the pouring or the pouring device moves. Provided is a method for placing or setting up earth and sand that can fix the measuring direction of the laser profiler at a right angle, increase the surveying area, and improve the surveying efficiency.
[0008]
[Means for Solving the Problems]
The present invention has two RTK-GPS antennas mounted on a horizontal member above a rotatable vertical axis, a motion compensation sensor is mounted on the rotatable vertical axis, and a laser profiler is attached to the lower end of the rotatable vertical axis. Set up the earth and sand and place a sanding device so that it is positioned below the laser profiler. The laser profiler can be rotated and fixed so that the laser is placed in a direction almost perpendicular to the moving direction of the sand and sanding device. The method comprises a method for controlling the placement or setting of earth and sand to control the height of setting or setting the earth and sand so that the measuring direction of the profiler is fixed.

FIG. 3 is a schematic side view of a placement base of a work-type management system disposed above the placement position of the placement apparatus or the placement position of the launch apparatus, and this production-type management system is shown in FIG. It is installed at the tip of the spreader 6 of the ship 1.
[0011]
Next, the work-type management system of FIG. 1 has a rotatable vertical shaft 2 disposed above the placement position of the placement device or the launch position of the launch device, and a laser profiler 4 is attached to the lower end thereof. In addition, two RTK-GPS antennas 3 are attached to the upper end of the rotatable vertical shaft 2, and a shake correction sensor 5 is attached to the vertical shaft 2. The RTK-GPS antenna 3 is connected to the vertical shaft 2. It is attached on the horizontal member 14 arrange | positioned.
[0012]
In FIG. 1, an antenna 23 that receives correction information from an RTK correction station (not shown) is installed in the vicinity of the RTK-GPS antenna 3, that is, in the spreader tip landing 20 provided with the spreader stand 7.
[0013]
In FIG. 1, the laser profiler is provided via a laser swivel base 8 and can be rotated by a rotator 9. In the figure, 21 indicates a swivel base.

Next, in the bridge-side system B of the launching vessel 1 shown in FIG. 2 in which the completed-type management system shown in FIG. 1 is installed at the tip of the spreader 6 on the hull, the laser profiler 4, the shake correction sensor 5, and two RTKs are provided. A spreader-side system comprising a processing unit such as a personal computer 26 for processing data from the GPS antenna 3 and comprising the laser profiler 4, the shake correction sensor 5, two RTK-GPS antennas 3, etc. The ground height data, slope data, and position data of each device of S are transmitted from the data relay unit to the bridge side system B by SS radio etc., and as shown in FIG. 3, from the bridge side system B to the spreader side Each measuring device of the system S is remotely operated.
[0015]
Furthermore, the measurement conditions of the system S on the spreader 6 side in this embodiment will be described with reference to FIG. 4. The height of the laser profiler 4 installed at the tip of the spreader 6 from the ground height is about 12 m, and the laser The theoretical measurement range with respect to the irradiation angle is 10.11 m for the radius of 40 °, 14.30 m for the radius of 50 °, and 20.78 m for the radius of 60 °, and the laser irradiation angles are shown in FIG.
