Suofengying Dam
The Suofengying Dam is a concrete gravity dam on the Wu River, northwest of Guiyang in Guizhou Province, China. It is located downstream of the Dongfeng Dam and upstream of the Wujiangdu Dam. The primary purpose of the dam is hydroelectric power generation and it supports a 600 MW power station. Construction on the dam began on 26 July 2002 and on December 18 of that year, the river was diverted. Pouring of roller-compacted concrete into the dam's body began on 14 January 2004 and in June, the dam began to impound its reservoir. On 18 August, the first generator was operational and the last two in 2005. The tall dam creates a reservoir with a capacity of . The dam's power station is located on its right bank and contains three 200 MW Francis turbine-generators.

Guiyang
Guiyang (; ; Mandarin pronunciation: ), historically rendered as Kweiyang, is the capital of Guizhou province of the People's Republic of China. It is located in the center of the province, situated on the east of the Yunnan–Guizhou Plateau, and on the north bank of the Nanming River, a branch of the Wu River. The city has an elevation of about . It has an area of . At the 2020 census, its population was 5,987,018, out of whom 4,506,134 lived in the six urban districts. A city with humid subtropical climate, Guiyang is surrounded by mountains and forest. The area, inhabited since at least the Spring and Autumn period, formally became the capital of the surrounding province in 1413, during the Yuan dynasty. The city is home to a large Miao and Bouyei ethnic minority population. Guiyang has a diversified economy, traditionally a center for aluminum production, phosphate mining, and optical instrument manufacturing. Following reforms, the majority of the city's economic output ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Francis Turbine
The Francis turbine is a type of water turbine. It is an inward-flow reaction turbine that combines radial and axial flow concepts. Francis turbines are the most common water turbine in use today, and can achieve over 95% efficiency. The process of arriving at the modern Francis runner design took from 1848 to approximately 1920. It became known as the Francis turbine around 1920, being named after British-American engineer James B. Francis who in 1848 created a new turbine design. Francis turbines are primarily used for producing electricity. The power output of the electric generators generally ranges from just a few kilowatts up to 1000 MW, though mini-hydro installations may be lower. The best performance is seen when the head height is between . Penstock diameters are between . The speeds of different turbine units range from 70 to 1000 rpm. A wicket gate around the outside of the turbine's rotating runner controls the rate of water flow through the turbine for d ...

Dams On The Wu River
A dam is a barrier that stops or restricts the flow of surface water or underground streams. Reservoirs created by dams not only suppress floods but also provide water for activities such as irrigation, human consumption, industrial use, aquaculture, and navigability. Hydropower is often used in conjunction with dams to generate electricity. A dam can also be used to collect or store water which can be evenly distributed between locations. Dams generally serve the primary purpose of retaining water, while other structures such as floodgates or levees (also known as dikes) are used to manage or prevent water flow into specific land regions. The earliest known dam is the Jawa Dam in Jordan, dating to 3,000 BC. The word ''dam'' can be traced back to Middle English, and before that, from Middle Dutch, as seen in the names of many old cities, such as Amsterdam and Rotterdam.

Gravity Dams
A gravity dam is a dam constructed from concrete or stone masonry and designed to hold back water by using only the weight of the material and its resistance against the foundation to oppose the horizontal pressure of water pushing against it. Gravity dams are designed so that each section of the dam is stable and independent of any other dam section. Characteristics Gravity dams generally require stiff rock foundations of high bearing strength (slightly weathered to fresh), although in rare cases, they have been built on soil foundations. The bearing strength of the foundation limits the allowable position of the resultant force, influencing the overall stability. Also, the stiff nature of the gravity dam structure is unforgiving to differential foundation settlement, which can induce cracking of the dam structure. Gravity dams provide some advantages over embankment dams, the main advantage being that they can tolerate minor over-topping flows without damage, as the concre ...

Hydroelectric Power Stations In Guizhou
Hydroelectricity, or hydroelectric power, is electricity generated from hydropower (water power). Hydropower supplies one sixth of the world's electricity, almost 4500 TWh in 2020, which is more than all other renewable sources combined and also more than nuclear power. Hydropower can provide large amounts of low-carbon electricity on demand, making it a key element for creating secure and clean electricity supply systems. A hydroelectric power station that has a dam and reservoir is a flexible source, since the amount of electricity produced can be increased or decreased in seconds or minutes in response to varying electricity demand. Once a hydroelectric complex is constructed, it produces no direct waste, and almost always emits considerably less greenhouse gas than fossil fuel-powered energy plants.

Dams In China
Dams and reservoirs in China are numerous and have had a profound effect on the country's development and people. According to the World Commission on Dams in 2000, there were 22,104 dams over the height of operating in China. Of the world's total large dams, China accounts for the most – of them; of which are used for irrigation. Accordingly, the oldest in China still in use belongs to the Dujiangyan Irrigation System which dates back to 256 BC. In 2005, there were over 80,000 reservoirs in the country and over 4,800 dams completed or under construction that stands at or exceed in height. As of 2007, China is also the world's leader in the construction of large dams; followed by Turkey, and Japan in third. The tallest dam in China is the Jinping-I Dam at , an arch dam, which is also the tallest dam in the world. The largest reservoir is created by the Three Gorges Dam, which stores 39.3 billion m3 (31,900,000 acre feet) of water and has a surface area of . Three Gorges is al ...

Roller-compacted Concrete
Roller-compacted concrete (RCC) or rolled concrete (rollcrete) is a special blend of concrete that has essentially the same ingredients as conventional concrete but in different ratios, and increasingly with partial substitution of fly ash for Portland cement. The partial substitution of fly ash for Portland Cement is an important aspect of RCC dam construction because the heat generated by fly ash hydration is significantly less than the heat generated by Portland Cement hydration. This in turn reduces the thermal loads on the dam and reduces the potential for thermal cracking to occur. RCC is a mix of cement/fly ash, water, sand, aggregate and common additives, but contains much less water. The produced mix is drier and essentially has no slump. RCC is placed in a manner similar to paving; the material is delivered by dump trucks or conveyors, spread by small bulldozers or specially modified asphalt pavers, and then compacted by vibratory rollers. In dam construction, roll ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wu River (Yangtze River Tributary)
The Wu River () is the largest southern tributary of the Yangtze River. Nearly its entire length of runs within the isolated, mountainous and ethnically diverse province of Guizhou. The river takes drainage from a watershed. The river flows through the Liupanshui, Anshun, Guiyang (the capital), Qiannan, and Zunyi Districts of Guizhou. All nine regions of the province have at least partial drainage to the river. Course The river begins as the ''Sancha'' in western Guizhou and flows eastwards about . It then bends north, west and south in a reach called the Yachi, and receives the Nanming River from the right. After the Yachi reach, the Wu makes a broad arc northeast through central Guizhou, picking up fifteen major tributaries including the Yu, Furong and Ya Rivers and flowing through several large hydroelectric dams. It then crosses the border into the provincial-level municipality of Chongqing, flows past Wushan, Badong and Zigui, and empties into the Yangtze River at Ful ...
