Tsushima Wellhead Construction Begins-International Highway Foundation News June Issue

◆ Tsushima Aren Slope mine entrance construction is about to begin




Construction of the wellhead of the Aren Slope on the west coast of Tsushima has finally begun, and detailed surveys were conducted for the setting of the wellhead for three days from May 200th to XNUMXth. A XNUMXm boring survey had already been conducted and the small hole was a landmark, but the excavator car "Back Four" made a loud noise and dug the small hole, and the construction started.


A tunnel entrance with a diameter of XNUMXm is installed here, and if you go XNUMXm, you will go down XNUMXm.A few hundred meters away, you will reach the Aren coast and the Western Channel, and XNUMX km away, you will find Geojedo, South Korea, and you will head west toward that point.Based on the results of this survey, we aim to install a wellhead by the end of July, and we will consider the construction method such as box culvert or liner plate, and full-scale construction will start from June.


Two years ago, a road was constructed for construction vehicles to reach this site, and the site was leveled as an office, warehouse, material storage area, and equipment installation area.After that, a groundbreaking ceremony will be held by the people concerned, and the construction will follow.This time, a wellhead will be installed at the red and white mark "Chohari" that can be seen in the photo.





The geology of Tsushima is the same as that of the Korean Peninsula, and it is a rocky island.There are few cultivated lands suitable for rice cultivation, and "Wei Zhi Yajinden" says, "The land is steep, there are many deep forests, and the roads are like the diameter of a bird deer. Then, take a boat and go north and south. "




Tsushima is a magnificent island that has been calmly located in the middle of the strong winds and rough waves of the Genkai Sea and has connected Japan and South Korea since ancient times.Even today, the natural environment remains the same, and even airports have to be built on top of mountains.The stratum is hard and is characterized by no earthquakes.As the construction progresses, modern civil engineering construction technology will reveal the geology of Tsushima.
