First, if you want to move a specific position such as the construction plan line, machine movement history line, and ring installation history line displayed on the display means 14 to the center of the display means 14, tap the place you want to move to the center. By doing so, the display position will move.

Next, the case of changing the display cross section will be described. When the user taps the section display button A displayed on the display means 14 with a finger, the display section is changed from the xz section to the xy section while maintaining the scale.

Next, a case of changing the display magnification of the construction plan line, machine movement history line, and ring installation history line will be described. Direct pinch-in/pinch-out operations can be performed on the construction plan line, machine movement history line, and ring installation history line displayed on the display means 14 to reduce/enlarge the display.

Next, a case of changing the scale of the construction plan line, machine movement history line, and ring installation history line will be described. When changing the scale, the user taps the number indicating the magnification of the scale display button B with a finger to display a pull-down menu, and select one from a plurality of scale rates set in the pull-down menu. You can change the scale by

Next, a case of moving the display positions of the construction plan line, machine movement history line, and ring installation history line currently displayed on the display means 14 will be described. When the display position is to be moved, the display position can be moved by touching any one of the display means 14 with a finger and performing a swipe operation in the longitudinal direction of the display means 14, for example.

As described above, according to the construction status display device 10 according to the present embodiment, in the construction of a shield tunnel, the construction plan line, machine movement history line, and ring installation history of the current construction status can be displayed without human intervention. Since the line can be displayed on the display means 14, the worker can easily visually recognize the construction status. As a result, it is possible to remarkably improve the working efficiency of constructing the shield tunnel.
In addition, as described above, since manual calculation and drawing are unnecessary when drawing construction plan lines, machine movement history lines, ring installation history lines, and the like, calculation errors and drawing errors can be reduced.
In addition, since the magnification of the construction planning line, machine movement history line, and ring installation history line displayed on the display means 14 can be freely set as needed, it becomes easy to check the construction status of the curved portion of the tunnel, especially the curvature. Highly adaptable to changes in As a result, the amount of meandering during shield machine travel is reduced, and segment cracking and chipping due to excavation by the shield machine are prevented, which contributes to improved tunnel quality and a reduction in work hours. will do.

In addition, in the above embodiment, the information required for construction is placed on a server on the Internet, so that multiple users can check the work status anytime and anywhere, and share the work status. , can improve work efficiency.

Further, in the above embodiment, the construction plan line information is obtained from the construction status drawing device 100, but it may be stored in the construction status display device 10 in advance. That is, only the construction status information that changes according to the progress of construction may be processed by the construction status drawing device 100 and acquired by the construction status display device 10 .

Further, in the present embodiment, it is assumed that the planned line information and the construction status information are obtained from the construction status drawing device 100 provided outside. It may be executed internally.

10 construction status display device, 12 storage means, 24 input operation determination means,
30 display processing means, 90 surveying device, 100 construction situation drawing device.
