In preparation for the opening of the Iki Exploration Inclined Shaft, scheduled for October 2017, the Japan-Korea Tunnel Technical Committee has been working together to develop plans for constructing the inclined shaft entrance. The outline of the plan has now been finalized, and as preparations for the start of on-site construction, on-site surveying and stake-setting (the process of determining the exact location of the building before construction begins) was carried out over two days, May 4th and 5th.
This time, a drone equipped with a camera was also introduced to efficiently install the stakes. The site has a large difference in elevation and is surrounded by windbreaks, which means visibility is severely limited, but by using the drone to check the overall terrain from above, work could be carried out more accurately and quickly. Once the investigation incline entrance is completed, it will also be possible to incorporate video taken by the drone into promotional videos.

Fortunately, the weather was good and the work itself progressed smoothly, and within the scheduled two days, the stakes were completed and the locations of the investigation incline entrance and temporary road were determined. On the second day, a meeting was held to discuss specific future construction plans, and it was decided that construction of the temporary road would take place in July and construction of the tunnel incline entrance would take place in September, with the opening ceremony scheduled for October.
If an investigation inclined tunnel entrance is completed in Iki, it will be the third location after Karatsu and Tsushima, and by confirming the three main bases on the Japanese side of the route, it is expected to have great significance for the realization of a Japan-Korea tunnel in the future.
