Curtain grouting l dry pulp (pulp) of masonry units of metal mesh node} mtm3m | m1m3 number of power generation 595373252925295d89783O127064964I53897325724 South Wing 3 a mixture of earth and rock cofferdam store with stone slope protection on both sides of the weir, impervious to prevent the use of high pressure spray cofferdam slope water erosion, save in the upstream weir weir and vertical joints, set the stone wrapped in wire cages and pick the first stream, reducing water erosion on the vertical weir. Second-phase cofferdam cofferdam remains are mixed with debris, which in the sluice and the plunge pool area by a permanent pier and the guide wall as a cofferdam, 100m after the plunge pool and 60m before the flood Kan Si by concrete gravity dam. 4.2 Construction of a dam on navigable Yu Chau Station during the construction of a project is to use the right side of the Cambodian narrow channel navigable river, channel width of 120m, the largest navigable discharge l200m / s, the open channel flow along the hood, the total surface of the water drop to 0 .4 m, basically meet the requirements of the construction of navigation. Phase II construction is built using the left bank of 6 holes have been completed sluice navigation. Illustrates the net width of each hole spillway 16m, chamber length 27m,moncler online, pier thick 3m,uggs, weirs and weir for the flat top width, crest elevation of 42.00m, plunge pool elevation 39.00ra, Mei Hom elevation 42.00m, the original bed elevation 42 .00 m or so, so the minimum navigation flows (Q = 67m / s) may meet the requirements of navigable water depth, the maximum navigable discharge (Q a 12e0m. / s),dsfdsfsd, the gate there was a slight shake the water hole, and a weak surface ripple, but there is no obvious scissors complete water export water gate hole almost steady, pseudo-smooth flow, no significant adverse flow patterns, the biggest gap is only 0.32m, the surface velocity is less than 3m / s, particularly near the two Gate No. 7 hole longitudinal cofferdam, as the role of concrete diversion weir vertical, so that the flow pattern of the gate hole better than the other holes, and because the direction of vessel-help control, so most boats run from May 7 through the hole lot During construction, temporary shipping guaranteed rate of 92.5 engineering characteristics, 5.0.1 Meng Zhou Hydropower Station with power generation, shipping and amenity, the development of tourism in the utilization efficiency. Project is completed, drainage of the channel 25km, improve navigation conditions, while improving the travel hotline as one of Guangdong Shaoguan City investment environment for attracting foreign investment, economic development, enhance the comprehensive strength has a huge role. 5.0.2 Power unit with bulb turbine group, which is the same type of hospital design a power plant put into operation the first power station of its turbine runner diameter 5.8m, is currently in progress in China-made Unit one of the largest mechanical and electrical and civil engineering design of its plant for the same type of power plant design offers other reference information. 5.0.3 for the sluice gate in the arc with flap gates. Use of such doors can make scheduling more flexible and convenient discharge is conducive to economic operation of power stations and reservoir floating material excretion. This door type, the application of engineering in the country have more steps. 5. () | 4 emptying system is down outlet discharge type, effectively shortening the segment until the total abolition of sedation, thereby reducing the length of the chamber, saving investments, reduce water consumption. j. Limestone bedrock at the dam site in the 0.5 development of a shallow karst surface, showing dissolution pits of varying sizes, melting tank and the cave, water seepage is very serious, so the basis of processing capacity, diversification of forms and take including exploration drilling, replacement, cement grouting, chemical grouting,uggs, high pressure spraying and other forms of treatment. 5.0.6 lock chamber under the gate first with soft sand and gravel piles and using high pressure jet grouting piles and ordinary high pressure jet grouting cement Week Results combined approach. According to the available data indicate that the basis of hydraulic structures in the processing of permanent high pressure jet grouting pile technology, is still rare. '5 .0.7 Yu Chau Hydropower Station Construction of the flood peak volume, continuous 2 years, 3 times over standard flood water had broken weir, making the already very tight rhyme duration more tense. 5,0.8 Meng Zhou Dam Power Plant Phase II has been built using sluice navigation, navigation in the permitted flow, the surface smooth, smooth flow, no flow without thorns, can meet the requirements of marine navigation, navigation guaranteed rate This successful experience of 92 other similar projects to provide reference information. 6 Conclusion Meng} Ill River Hydropower Station on the North River as the first l steps, in addition to power generation efficiency, there are shipping and amenity, the development of tourism in the comprehensive utilization of lessons learned power plant construction, the city of Shaoguan has a huge role in economic development; Meanwhile South Africa in Bangladesh Institute designed the construction of hydropower dam of bulb turbine unit installed in the process, solve many problems, accumulated some experience, these are the same type of power plant design to provide a reference for information 相关的主题文章： sdfsgfdsf Batch mixing method for dam concrete Res uggs nederland When the dam with the water curtain uggs nederland Water quality in China in 2009 (Yu) |
