DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to construction management in civil engineering works, and more particularly to management of unmanned construction using a GPS positioning system (positioning system using artificial satellites) and a remotely operated construction machine. The present invention relates to a method and apparatus for managing a spread area when a concrete block or the like (hereinafter referred to as "sand etc.") is spread at a predetermined spread place in an unmanned construction area. .

[0002]

2. Description of the Related Art In the case of constructing a foundation of a structure or the like, a method of laying sand or the like on a predetermined construction site and rolling the laid surface with a rolling machine is often adopted. Further, in the construction of a dam, a method of constructing a dam may be adopted by laying sand or the like and rolling the surface thereof repeatedly in multiple stages. In these cases, in order to obtain an accurate and lean structure that is faithful to the original construction plan, its construction management is important. It is extremely important to manage the leveling area when performing this. As a method of managing the leveling area, a method of marking the ground at a predetermined construction location to indicate the leveling area is adopted. The worker who performs the leveling operation can perform an accurate leveling operation by using the marking indicating the leveling range as a mark.

[0003] As a general method of performing the marking for indicating the spread area, a survey of the spread area is performed in advance at a predetermined construction place, and a construction plan line is determined.
There is a method of performing marking with a marking device having a spray gun and containing paint. As a method of operating the marking device, there are a method using human power and a method using a remote control device. In the manual method, the marking device is manually moved, and when the marking device coincides with the construction plan line, the marking is performed by operating the spray gun of the marking device. In the method using a remote control device, a remote control device (for example, a radio control device) is attached to the marking device, a plurality of TV cameras are set around the construction planning line, and the images projected by the TV cameras are referred to. Then, the marking device is moved by remote control, and when the marking device matches the construction plan line, the marking is performed by operating the spray gun of the marking device by remote control.

[0004]

In realizing a method of marking a leveling area by the above-described method, there is a premise of marking by a marking device.
It is essential to measure the leveling area at the construction site. In addition, in the method of performing marking by hand, it is necessary for a worker to inevitably enter a construction place. By the way, work may be dangerous depending on the situation of the construction site where the leveling work is performed, and in such a construction site, unmanned construction may be requested or unmanned construction may be required. In such a case, it is impossible to perform surveying of the construction site in advance or to perform marking by human power, and as a substitute method, without performing surveying of the spread area in the construction site in advance, and
It is required to provide a method capable of performing an automatic marking operation using a remote control device.

However, in the marking method using the remote control device according to the prior art, it is still necessary to measure the spread area at the construction site in advance, and to refer to an image projected by a television camera. The disadvantage is that strict construction management cannot be performed because the marking device is only operated by remote control, and the marking is not performed while grasping the position of the marking device and the separation between the construction planning line and the marking device in real time. is there. Therefore, when the control of the leveling range with high accuracy is required, it is insufficient, and in order to solve the above-mentioned problem, without previously measuring the leveling range at the construction site, and Provide a leveling range management method and leveling range management device that can perform strict construction management, as a result, it is possible to perform quick and accurate work,
It is necessary to contribute to improvement of workability in unmanned construction.

Make corrections to eliminate the separation, move the leveling range management device along the construction plan line, and display the trajectory of the leveling range management device on the construction plan line, thereby leveling the construction site. Specify range Characterized Rukoto, there is provided a laying leveling range management method.
