Twin River Bridges (Chongqing)
The Dongshuimen Bridge () and the Qiansimen Bridge (), known collectively as the Twin River Bridges, are a pair of bridges that form a road and rail connection in Chongqing, China. Consisting of two cable-stayed bridges and a tunnel across the Yuzhong peninsula where the heart of Chongqing's commercial & financial district Jiefangbei CBD is located, the connection opened in 2014. Planning Planning for the Twin River Bridges dates to 1947, when the alignment of the connection appeared in planning documents for Chongqing. Right of way for planned connection has been preserved since then. The plan for the crossings has always included transit rail. By the time design of the Twin River Bridges began in 2008, it had been determined that the bridges could not be identical. Crossing of the Yangtze on the south side of the Yuzhong peninsula would require a longer main span and allow for two tower in the water. A deep shipping channel in the Jialing River would not allow a second tow ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yangtze River
The Yangtze or Yangzi ( or ; ) is the longest list of rivers of Asia, river in Asia, the list of rivers by length, third-longest in the world, and the longest in the world to flow entirely within one country. It rises at Jari Hill in the Tanggula Mountains (Tibetan Plateau) and flows in a generally easterly direction to the East China Sea. It is the List of rivers by discharge, seventh-largest river by discharge volume in the world. Its drainage basin comprises one-fifth of the land area of China, and is home to nearly one-third of the demographics of China, country's population. The Yangtze has played a major role in the history of China, history, culture of China, culture, and economy of China. For thousands of years, the river has been used for water, irrigation, sanitation, transportation, industry, boundary-marking, and war. The prosperous Yangtze Delta generates as much as 20% of historical GDP of China, China's GDP. The Three Gorges Dam on the Yangtze is the list ...

Bridges In Chongqing
A bridge is a structure built to span a physical obstacle (such as a body of water, valley, road, or rail) without blocking the way underneath. It is constructed for the purpose of providing passage over the obstacle, which is usually something that is otherwise difficult or impossible to cross. There are many different designs of bridges, each serving a particular purpose and applicable to different situations. Designs of bridges vary depending on factors such as the function of the bridge, the nature of the terrain where the bridge is constructed and anchored, and the material used to make it, and the funds available to build it. The earliest bridges were likely made with fallen trees and stepping stones. The Neolithic people built boardwalk bridges across marshland. The Arkadiko Bridge (dating from the 13th century BC, in the Peloponnese) is one of the oldest arch bridges still in existence and use. Etymology The ''Oxford English Dictionary'' traces the origin of the wo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cable-stayed Bridges In China
A cable-stayed bridge has one or more ''towers'' (or ''pylons''), from which cables support the bridge deck. A distinctive feature are the cables or stays, which run directly from the tower to the deck, normally forming a fan-like pattern or a series of parallel lines. This is in contrast to the modern suspension bridge, where the cables supporting the deck are suspended vertically from the main cable, anchored at both ends of the bridge and running between the towers. The cable-stayed bridge is optimal for spans longer than cantilever bridges and shorter than suspension bridges. This is the range within which cantilever bridges would rapidly grow heavier, and suspension bridge cabling would be more costly. Cable-stayed bridges were being designed and constructed by the late 16th century, and the form found wide use in the late 19th century. Early examples, including the Brooklyn Bridge, often combined features from both the cable-stayed and suspension designs. Cable-stayed ...

List Of Longest Cable-stayed Bridge Spans
This list ranks the world's cable-stayed bridges by the length of main span, i.e. the distance between the suspension towers. The length of the main span is the most common way to rank cable-stayed bridges. If one bridge has a longer span than another, it does not mean that the bridge is the longer from shore to shore, or from anchorage to anchorage. However, the size of the main span does often correlate with the height of the towers, and the engineering complexity involved in designing and constructing the bridge. Cable-stayed bridges with more than three spans are generally more complex, and bridges of this type generally represent a more notable engineering achievement, even where their spans are shorter. Cable-stayed bridges have the second-longest spans, after suspension bridges, of bridge types. They are practical for spans up to around . The Russky Bridge over the Eastern Bosphorus in Vladivostok, Russia, with its span, has the longest span of any cable-stayed bridge, disp ...

Nan'an District
Nan'an District (), is one of the six central districts of Chongqing municipality, China. It covers an area of 262.43 km2, with 44 km2 covered with forests and woods. It has an estimated population of 891,000 in late 2017. Geography The Yangtze River curves around the north and west border of Nan'an district for about 45 kilometers. The river separates Nan'an from its neighbouring districts such as Jiulongpo, Yuzhong, Jiangbei, and Yubei. The bridges crossing the Yangtze River are the primary passage for transportations to and from the other side of the river. Ferries are also available as a backup and they used to be the only connection to the central part of downtown Chongqing before the first bridge was built in the early 1980s. Nan'an shares the border on the south and east land area with Banan. History Nan'an district is one important part of the historical city Chongqing. It was first established in 1929 as an administrative region when the city underwent exp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Three Gorges Dam
The Three Gorges Dam is a hydroelectric gravity dam that spans the Yangtze River by the town of Sandouping, in Yiling District, Yichang, Hubei province, central China, downstream of the Three Gorges. The Three Gorges Dam has been the world's largest power station in terms of installed capacity (22,500 MW) since 2012. The dam generates an average 95±20 TWh of electricity per year, depending on annual amount of precipitation in the river basin. After the extensive monsoon rainfalls of 2020, the dam's annual production nearly reached 112 TWh, breaking the previous world record of ~103 TWh set by Itaipu Dam in 2016. The dam body was completed in 2006. The power plant of the dam project was completed and fully functional as of July 4, 2012, when the last of the main water turbines in the underground plant began production. Each main water turbine has a capacity of 700 MW. Coupling the dam's 32 main turbines with two smaller generators (50 MW each) to power the p ...

Shuttle (weaving)
A shuttle is a tool designed to neatly and compactly store a holder that carries the thread of the weft yarn while weaving with a loom. Shuttles are thrown or passed back and forth through the shed, between the yarn threads of the warp in order to weave in the weft. The simplest shuttles, known as "stick shuttles", are made from a flat, narrow piece of wood with notches on the ends to hold the weft yarn. More complicated shuttles incorporate bobbins or pirns. In the United States, shuttles are often made of wood from the flowering dogwood, because it is hard, resists splintering, and can be polished to a very smooth finish. In the United Kingdom shuttles were usually made of boxwood, cornel, or persimmon. Flying shuttle Shuttles were originally passed back and forth by hand. However, John Kay invented a loom in 1733 that incorporated a flying shuttle. This shuttle could be thrown through the warp, which allowed much wider cloth to be woven much more quickly and made the develo ...

Chongqing Rail Transit
The Chongqing Rail Transit (branded as CRT; also known as Chongqing Metro) is the rapid transit system in the city of Chongqing, China. In operation since 2005, it serves the transportation needs of the city's main business and entertainment downtown areas and inner suburbs. , CRT consisted of nine lines, with a total track length of . Lines 1, 4, 5, 6, 9, 10 and the Loop line are conventional heavy-rail subways, while Lines 2 and 3 are high-capacity monorails. To keep up with urban growth, construction is under way on Line 18 and Jiangtiao line, in addition to extensions to Lines 4, 5, 6, 9, 10. A network of 18 lines is planned. The Chongqing Rail Transit is a unique transit system in China because of the geography of Chongqing being a densely-populated but mountainous city, with multiple river valleys. Two lines use heavy-monorail technology, leveraging the ability to negotiate steep grades and tight curves and rapid transit capacity. They are capable of transporting 32,00 ...
