Recently, the internationally renowned think tank YINGCAI Institute believes that the construction of the Tsushima Kaikyo tunnel is ripe. China, Japan and South Korea will already be the world's top 2020 economies in 10, and the distribution of people and goods in four countries, including North Korea, will recover the enormous cost of building a strait tunnel. Because it is enough.
The Tsushima Strait undersea tunnel will be constructed between Saga Prefecture in Kyushu, Japan and Busan, South Korea.Excavate 100 to 200 meters from the basement of Zhenxi Town, Saga Prefecture, and cross the bottom of the Iki Strait 17 kilometers, the bottom of the Iki Island 18 kilometers, and the bottom of the Tsushima Strait 47 kilometers toward Tsushima Island.It passes through the Tsushima Strait (23 km), the bottom of the strait (68 km), and Geojedo (30 km), reaching a depth of 300 meters.250 kilometers long, the longest in the world in length and depth.The submarine tunnel is planned to build a tunnel with a diameter of 11 meters for high-speed passenger and freight trains, and the total cost of the project is estimated to be about 800 billion US dollars. And Korea is responsible for Tsushima Island or Busan.The greatness of the vision, the huge scale, and the difficulty and risk of the project are peculiar.
At the same time, the construction of the East Asian high-speed railway is also planned, starting from Beijing, entering the Korean Peninsula via northeastern China, connecting Pyongyang and Seoul, passing through the Tsushima Strait, and in the undersea tunnel. Connects Japan's Osaka and Tokyo.The high-speed rail connects world-class cities such as Beijing, Seoul, Tokyo and Osaka at a speed of 350 kilometers per hour.Professor Sasaki of Waseda University in Japan believes that the East Asian high-speed railway will be the high-speed railway with the largest passenger transportation volume in the world.You can also have breakfast in Beijing and lunch in Tokyo.The annual net profit of high-speed rail reaches US $ 130 billion, and the full construction cost is expected to be recovered within 10 years.
The construction of the Tsushima Strait tunnel and the East Asian high-speed railway can be carried out at the same time.Estimated construction period is 7 years.The investment will be US $ 700 billion for the Tsushima Strait Tunnel and US $ 780 billion for the East Asian high-speed railway, with a total investment of US $ 2 billion for the two major projects.It connects super-large cities such as Beijing, Tianjin, Pyongyang, Seoul, Busan, Osaka, and Tokyo, and is the transportation trunk line that boasts the largest number of passengers in the world.
