Jeju Undersea Tunnel
The Jeju Undersea Tunnel (제주해저터널) is a proposed undersea tunnel project to connect the South Korean provinces of South Jeolla and Jeju across the Jeju Strait, with intermediate stops at the islands of Bogildo and Chujado. The proposed 73 km tunnel is projected to take 11 years to complete at an estimated cost of 14.6 trillion South Korean won (11.2 billion US Dollars). History The underwater tunnel would allow the KTX bullet train to connect the port city of Mokpo and Jeju island. On June 19 2013, the provincial government requested that the central government include 10 billion Korean won as part of the 2014 fiscal year budget to study and plan for the tunnel. The total length of the proposed railway is 167 km, including a 66 km surface interval from Mokpo to Haenam, a 28 km bridge section from Haenam to Bogil Island, and a 73 km stretch from Bogil to Chuja and Jeju Islands. The provincial government predicts that by the time the project reaches completi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Undersea Tunnel
An underwater tunnel is a tunnel which is partly or wholly constructed under the sea or a river. They are often used where building a bridge or operating a ferry link is unviable, or to provide competition or relief for existing bridges or ferry links.Sullivan, WalterProgress In Technology Revives Interest In Great Tunnels New York Times, June 24, 1986. Retrieved 15 August 2010. While short tunnels are often road tunnels which may admit motorized traffic, unmotorized traffic or both, concerns with ventilation lead to the longest tunnels (such as the Channel Tunnel or the Seikan Tunnel) being railway electrification systems, electrified rail tunnels. Types of tunnel Various methods are used to construct underwater tunnels, including an immersed tube and a submerged floating tunnel. The immersed tube method involves steel tube segments that are positioned in a trench in the sea floor and joined together. The trench is then covered and the water pumped from the tunnel.

Honam High Speed Railway
The Honam high-speed railway, also known as Honam HSR, is a high-speed rail between Osong (on the existing Gyeongbu high-speed railway) and Mokpo in South Korea. The line is a part of Korail's Korea Train Express (KTX) system, accelerating Seoul–Mokpo and Seoul–Gwangju KTX high-speed services which currently use the existing conventional Honam Line. On April 1, 2015, the line was inaugurated by the South Korean President Park Geun-hye with the attendance of 1200 invited guests and members of the public at Gwangju Songjeong Station in Gwangju, the line's terminus. The line diverges from Osong station on the Gyeongbu high-speed railway, and stops at Gongju, Iksan, Jeongeup Stations. Journey times between Seoul and Gwangju has been cut from 2 h 40 min to just 90 min, making daily commuting possible. The Honam HSR is intended to bring business, and economic opportunities to the province of Jeollanam-do, which has seen slower development than other parts of South Korea. The line ha ...

Unification Church Political Involvement
The Family Federation for World Peace and Unification, widely known as the Unification Church, is a new religious movement, whose members are called Unificationists, or "Moonies". It was officially founded on 1 May 1954 under the name Holy Spirit Association for the Unification of World Christianity (HSA-UWC) in Seoul, South Korea, by Sun Myung Moon (1920–2012). Moon and his wife Hak Ja Han were the leaders of the church and are honored by its members as their "True Parents." The beliefs of the Unification Church are based on Moon's book the ''Divine Principle.'' The movement is well known for its "Blessing" or mass wedding ceremonies. The Unification Church has been criticized for its teachings and for its social influence, with some critics calling it a "dangerous cult". Its involvement in politics include anti-communism and support for Korean reunification.Kent, Stephen A., ''From Slogans to Mantras: Social Protest and Religious Conversion in the Late Vietnam War Era'' ( ...

Tunnels In South Korea
A tunnel is an underground passageway, dug through surrounding soil, earth or rock, and enclosed except for the entrance and exit, commonly at each end. A pipeline is not a tunnel, though some recent tunnels have used immersed tube construction techniques rather than traditional tunnel boring methods. A tunnel may be for foot or vehicular road traffic, for rail traffic, or for a canal. The central portions of a rapid transit network are usually in the tunnel. Some tunnels are used as sewers or aqueducts to supply water for consumption or for hydroelectric stations. Utility tunnels are used for routing steam, chilled water, electrical power or telecommunication cables, as well as connecting buildings for convenient passage of people and equipment. Secret tunnels are built for military purposes, or by civilians for smuggling of weapons, contraband, or people. Special tunnels, such as wildlife crossings, are built to allow wildlife to cross human-made barriers safely. Tunne ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Water Transport In South Korea
Water (chemical formula ) is an inorganic, transparent, tasteless, odorless, and nearly colorless chemical substance, which is the main constituent of Earth's hydrosphere and the fluids of all known living organisms (in which it acts as a solvent). It is vital for all known forms of life, despite not providing food, energy or organic micronutrients. Its chemical formula, H2O, indicates that each of its molecules contains one oxygen and two hydrogen atoms, connected by covalent bonds. The hydrogen atoms are attached to the oxygen atom at an angle of 104.45°. "Water" is also the name of the liquid state of H2O at standard temperature and pressure. A number of natural states of water exist. It forms precipitation in the form of rain and aerosols in the form of fog. Clouds consist of suspended droplets of water and ice, its solid state. When finely divided, crystalline ice may precipitate in the form of snow. The gaseous state of water is steam or water vapor. Water covers ab ...

Rail Transport In South Korea
Rail transport in South Korea is a part of the transport network in South Korea and an important mode of the conveyance of people and goods, though railways play a secondary role compared to the road network. The network consists of of standard-gauge lines connecting all major cities with the exception of Jeju City on Jeju Island, which does not have railways; of the network, are double-tracked and are electrified. In 2018, rails carried 11.5 percent of all traffic in South Korea134.8million passengers and 30.9milliontonnes of freightwith roads carrying 88.3 percent. Passenger and freight services are primarily provided by the Korea Railroad Corporation, branded as Korail, a state-owned enterprise under the Ministry of Land, Infrastructure and Transport, although some rail lines and services, including high-speed intercity rails and metropolitan rapid transit, are operated by private companies. The Korea National Railway (formerly the Korea Rail Network Authority), anoth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Transport In South Korea
Transportation in South Korea is provided by extensive networks of railways, highways, bus routes, ferry services and air routes that traverse the country. South Korea is the third country in the world to operate a maglev train, which is an automatically run people mover at Incheon International Airport. History Development of modern infrastructure began with the first Five-Year Development Plan (1962–66), which included the construction of 275 kilometers of railways and several small highway projects. Construction of the Gyeongbu Expressway, which connects the two major cities of Seoul and Busan, was completed on 7 July 1970. The 1970s saw increased commitment to infrastructure investments. The third Five-Year Development Plan (1972–76) added the development of airports, seaports. The Subway system was built in Seoul, the highway network was expanded by 487 km and major port projects were started in Pohang, Ulsan, Masan, Incheon and Busan. The railroad network experien ...

Coastal Construction
The coast, also known as the coastline or seashore, is defined as the area where land meets the ocean, or as a line that forms the boundary between the land and the coastline. The Earth has around of coastline. Coasts are important zones in natural ecosystems, often home to a wide range of biodiversity. On land, they harbor important ecosystems such as freshwater or estuarine wetlands, which are important for bird populations and other terrestrial animals. In wave-protected areas they harbor saltmarshes, mangroves or seagrasses, all of which can provide nursery habitat for finfish, shellfish, and other aquatic species. Rocky shores are usually found along exposed coasts and provide habitat for a wide range of sessile animals (e.g. mussels, starfish, barnacles) and various kinds of seaweeds. Along tropical coasts with clear, nutrient-poor water, coral reefs can often be found between depths of . According to a United Nations atlas, 44% of all people live within 5 km (3.3mi) of ...

Japan–Korea Undersea Tunnel
The Japan–Korea Undersea Tunnel, or Korea–Japan Undersea Tunnel, is a proposed tunnel project to connect Japan with South Korea via an undersea tunnel crossing the Korea Strait that would use the strait islands of Iki and Tsushima, a straight-line distance of approximately at its shortest.Sullivan, WalterProgress In Technology Revives Interest In Great Tunnels ''New York Times'', June 24, 1986. Retrieved August 15, 2010. The proposal, which has been under discussion intermittently since 1917, was followed with more concrete planning during the early 1940s. It was not pursued, however, until after World War II. In early 2008, the proposal came under renewed discussions by 10 senior Japanese lawmakers, who established a new committee to pursue it.Korea-Japan Tunnel Finally in Sight [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tunnel Boring Machine
A tunnel boring machine (TBM), also known as a "mole", is a machine used to excavate tunnels with a circular cross section through a variety of soil and rock strata. They may also be used for microtunneling. They can be designed to bore through hard rock, wet or dry soil, or sand. Tunnel diameters can range from (micro-TBMs) to to date. Tunnels of less than a metre or so in diameter are typically done using trenchless construction methods or horizontal directional drilling rather than TBMs. TBMs can be designed to excavate non-circular tunnels, including u-shaped, horseshoe, square or rectangular tunnels. Tunnel boring machines are used as an alternative to drilling and blasting (D&B) methods in rock and conventional "hand mining" in soil. TBMs have the advantages of limiting the disturbance to the surrounding ground and producing a smooth tunnel wall. This significantly reduces the cost of lining the tunnel, and makes them suitable to use in urban areas. The major disadvan ...
