[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to an excavation control device for an underground excavator that excavates tunnels such as communication cables, electric wires, water and sewage pipes, and gas pipes without excavating the ground such as a road.
[0002]
[Prior art]
Conventionally, when constructing conduits for communication cables, electric wires, water and sewage pipes, gas pipes, etc. underground, a method has been adopted in which the ground of the road is cut open to dig deep trenches and buried pipes are buried in these trenches. I have been.
However, in such a road excavation method, traffic is cut off, which has a large effect on the road conditions, and excavators dig deep trenches, so that noise and vibration are generated, which greatly affects the living environment. There's a problem.
[0003]
Therefore, in recent years, excavation methods for excavating a horizontal tunnel in the ground without forming a ground and forming a pipeline in the tunnel have been developed and put into practical use.
In the construction of this excavation method, a starting shaft is dug in a part of the ground that is one end of the tunnel, and a reaching shaft is dug in a part of the ground that is the other end of the tunnel, and an underground excavator is installed in the starting shaft. Is installed, and the propulsion device is pushed forward in the ground by the main pushing device. Then, when the propulsion device advances by a predetermined stroke, a propulsion pipe is connected to the rear side of the propulsion device, the propulsion tube is pressed by a main pushing device, and the propulsion device on the tip side is advanced with the propulsion tube, The propulsion device is advanced to the arrival shaft while sequentially adding propulsion pipes in such a procedure, and a tunnel is dug to construct a predetermined pipeline. Then, the propulsion device that has reached the reaching shaft is taken out from the reaching shaft.
[0004]
As the propulsion device, a press-fitting type having a press-fitting head is generally used in the case of a viscous ground or a sandy ground, and an excavation type having a cutter head is used in the case of a gravel ground or a cobblestone ground. A hydraulic jack or the like is used as the main pushing device.
[0005]
According to such an excavation method, for example, a tunnel having a diameter of 30 to 40 cm can be excavated to a length of about 500 m. By controlling the direction correcting mechanism such as a hydraulic jack provided in the propulsion device, it is possible to dig a curved tunnel having a radius of curvature of about 100 m along a curved road.
[0006]
By the way, as a conventional excavation control device of such an underground excavator, an operation control panel is installed at a construction site where excavation work is performed, and a propulsion state such as a posture of a propulsion device is displayed on a display of the operation control panel. In addition to the trajectory of the propulsion line, it is also possible to display the control amount of direction correction, etc., while confirming the information on this display, and using the operation control panel, the main push jack of the main push device, the tip jack of the propulsion device, the direction correction jack etc It was common to move and control the excavation movement.
[0007]
[Problems to be solved by the invention]
However, in such a conventional excavation control device, an operator having specialized skills regarding excavation work is resident at each construction site, and the operation control panel is operated while responding to the constantly changing excavation conditions or the excavation environment at the site. Excavation control was implemented using For this reason, the excavation quality has been uneven due to the technical capabilities possessed by individual operators.
[0008]
Also, in recent years, as excavation work by the non-cutting method has become longer, the possibility of occurrence of troubles such as a sudden change in soil properties and equipment failure has increased. When such troubles occur, each operator tries to resolve the troubles based on the judgment backed by his / her own construction experience. You will need technical assistance from engineers. However, in particular, when construction is being performed in a remote location, technical assistance must be relied on telephone communication, and the trouble may not be solved. In such a case, a specialized engineer must go to the site directly from the management center and take other measures, which not only requires a great deal of waste, but also results in a delay in the excavation work during that time. This hindered efficiency and reduced the efficiency of construction.
[0009]
The present invention has been made based on such circumstances, and an object of the present invention is to provide an apparatus capable of controlling excavation of an underground excavator from a remote place other than a construction site where excavation work is performed. What you are trying to do.
[0010]

By taking such measures, the remote control device can be installed in a remote place other than the excavation site where the operation control panel is installed, and while the specialist is located in a remote place. Therefore, it becomes possible to control the excavation operation of the underground excavator as if the operation control panel was operated at the construction site.
[0012]

[0018]
That is, in the case of the wired system, a personal computer having a communication interface 51 such as RS232C and a modem 52 is used as the communication control device 5. In each of the construction sites A, B,..., N, the communication interface 51 of the communication control device 5 and the communication interface 31 provided in the operation control panel 3 are connected by an interface cable 81.

As a result, it is no longer necessary for specialist technicians to go to the site where the trouble has occurred, which can reduce the enormous waste required for the movement, and can also eliminate the situation where excavation work is delayed, prevent efficiency deterioration, and efficiently and smoothly. It is possible to realize a smooth excavation work and to ensure the construction quality.
[0023]
Further, even if there is a difference in the technical capabilities of the operators at the construction sites A, B,... Variations in construction quality can be prevented, and high-quality construction can be achieved. Similarly, the operators at each of the construction sites A, B,..., N can also view the appropriate operations of the specialized technicians, so that there is a high possibility that the operators will become highly skilled operators in a short time. , Operator shortage can be eliminated.
[0024]
Since the excavation data at each of the construction sites A, B,..., N can be collectively collected at the operation center X, by accumulating the data and creating a database, the know-how of the excavation technology can be collected and used efficiently. It is possible. At the same time, the use of the excavation database, the automatic direction control software and the remote control system makes it possible to automatically realize the control equivalent to that of a professional engineer.
[0025]
