三峡大坝英语导游词 三峡大坝英语导游词 The Three Gorge Dam Dear friends Welcome to Yichang.Im your tour guide in Yichang, my name is Wang Jing, you can call me Xiao Wang.Im from Xiazhou International Travel Service.Now, bring your belongings with you, and follow me to coach.Ok, let me introduce our driver, his name is Li Yao, you can call him Li Shifu, here is our itinerary for these days.If you have some difficulties, please let me know, I would be very happy to help you.My contact way is in it.You must be very tired after a long journey.We are going to Taohualing Hotel and take a rest.Here is our hotel, please give me your ID and Ill help you to register.Hi, here are your room cards and remember well meet at the gate at 8:00 tomorrow morning, we will visit Three Gorges Dam. Hi, good morning, You look better than yesterday.Now collect your belongings and get on the bus.Hello, we ll visit the Three Gorges Dam.It may take you half an hour bus from the Yichang urban to the dam area.Let me tell you something about it, The Three Gorges Dam is the first 5A-cla tour sites in Yichang and has been listed as one of the first national demonstrations on industrial tourism.As the world largest hydropower project, the Three Gorges Project is located at the Zhongbao Island near Sandouping in Yichang, and about 37 km away from the Gezhouba Hydropower project in the downstream.The whole construction is completed according to the plan of “first cla development, complete construction, reservoir by stages, and continuous immigrants”.The total construction period lasted for 17 years including three phases.The first phase was from 1993 to 1997; the second phase was from 1998 to 2003; and the third one is from 2004 to 2009.The total investment is estimated to be RMB 203.9 billion Yuan.The reservoir will submerge about 1.1318 million people to immigrate to higher place.When this project is finally completed, the reserved water level will reach 175 m, with total reservoir capacity of 39.3 billion cubic meters. Tanzi Ling (Peak Crock) Scenic Spot Here we are the top of the Dam area, the Tangzi Ling (Peak Crock),with a height of 242.48 m.And we can overlook the general of Three Gorges Project and Dam Area. The name is from its shape of upside down crock.Its said that in the ancient time, when Da Yu led people dredge the watercourse and fought against the flood, he was too involved to enter the door even when he paed his home third times.With the help of magic bull, he excavated 200-km watercourse.In order to thank his achievement, people sent him 24 pigs and a big crock of wine by boat.When the boat reached Sandouping (the Project site), they saw the magic bull going away on clouds and leaving its image in mountains, where was called the Bull Rock later.Hastily, Da Yu followed the bull, leaving a big rock for memory.People were deeply moved by what happened, and kept the boat waiting in the river.Later, the boat turned into an island, called Zhongbao Island.24 pigs were down into the river turning into 24 reefs.And that big wine crock was set in the left bank turning into now called Tanzi Ling. The Model Hall of the Three Gorges Project 模型室 On the Tanzi Ling, we first visit the Hall of the Project Model, where shows the whole mini construction of the Project.And there we can view real part of the Eternal Riverbed Rock, the Sill under the Dam and the Damming Rock.Then we climbed the peak top and overlook the overall appearance of the Three Gorges Project. These models lay out the complete project with a scale of 1:850.As the largest one in the world, the Project with large installed capacity and huge engineering scope will bring out marked and integrated benefits.With13 tops in the world, this project is not only for flood control but also giving great benefits to the later generations, showing great role in comprehensive national strength increase of China. The Project body consists of the main dam, generation stations and navigation building.The concrete gravity main dam is about 2309 m in length and 185 m in height.And the dam top width is 15 m, while the bottom one is 124 m.The discharge dam is in the middle of the Main Dam, while power generation stations are in both ends.The 483-meter discharge dam consists of 22 overflows and 23 deep overflows, functioning as flood discharge and sludge remove. The generation stations are in the both ends of the main dam.14 generators are installed for left generation stations, while 12 for right ones.With 700 thousand kW capacity for each, the installed capacity will reach 18.2 million kW and 84.7 billion kW/h each year, which accounts for 1/9 of the nation total and is 5.3 times of the Gezhouba projects total. The navigation buildings consist of two-way 5-stage ship lock and ship elevator.The ship lock is 6442 m in length and 300 m in width, with two way and 5 stages.And it is divided into 10 rooms, 280 m in length and 34 m in width for each, with minimum water depth of 5 m; the fall between upstream and downstream is 113 m, suitable for 10 thousand tonnages ships.But it takes almost two and half hour to pa through the lock.Therefore, the ship elevator is designed for fast navigation for medium and small ships below 3000 tonnages.The elevator container is about 120 m in length and 18 m in width, with minimum water depth of 3.5 m.And it only needs 30-40 minutes for these ships to pa through the dam. Eternal Riverbed Rock万年江底石 This is a riverbed rock.Its granite, with weight over 20 ton.Commonly we call it the “Eternal Riverbed Rock”.Actually, its over 0.8 billion years old.From this rock, people get to know the very past of the Yangtze River.Now, on the rock, we can see some bore holes, which were left by the geologists and the hydropower s when investing the dam site.And this rock was originally excavated from the footing groove of cofferdam'k?f?,d?m during the 2 phase construction period. The Damming Rock 截流石 This is the damming rock, a double sized model.We put it here to make it a symbol of the spirit of water controlling.The real rock is triangle tetrahedro, with each side length of 2.5m, and weight of 28 ton.In 1981, rocks used for damming the Yangtze River at the Gezhouba Project were just half the size.This shape was approved by the modern technology as the best to fight against the rip current.When thrown into the water, its sharp edge cuts into silt to make it stable in the flow.So rocks of this shape, representing the modern hydro technology, have been applied for both Gezhouba Project and Three Gorges Project. The Sill under the Dam This columned rock pillar is a sample of the sill under the dam.Before the construction, there used to be an island, Zhongbao Island, in the center of Yangtze River.And this rock was drilled out from the rock formation under the island.Been considered and approved over 70 years, the Yangtze Three Gorges Project site was finally set at the Zhongbao Island.And now, this island is disappeared.So this rock shows both memory and witne for the great Three gorges Project. The great Emboment浮雕群 This emboment is called “the headstream breeding the life”.The big copper plate emboment in the front looks like a generating wheel in water, and 3 strong men are rotating it hand, representing a spirit that the world is living on the water.On two sides of the copper emboment, there is a tiger and a phoenix telling the specific geographic location and the cultural background of the Three gorges Project because the Chu People adored the phoenix while the Ba people adored the tiger.The commanding tiger and the illustrious phoenix are the best representatives of the people in the Three Gorges to tell the world their dreams of the dam.Please take a careful look at the both sides, the figures on the top right side are a modern man and the legend Da Yu.They are lapping over each other to show two Chinese characters, the “big” and the Man”.With a sill rock core in hand, the modern man represents the advanced hydropower technology.A shovel in hand, the legend Da Yu tells the long history of the Chinese fighting against the floods.The background here is the great scenery of the dam construction.Starting from the left, it also shows the sceneries of the great immigration movement, the industries of the stockbreeding and the shipping.There are characters like laborious women, lovely kids, and the reliable husband.Dramatically, there are three fairies flying there in the sky.Together with the other fairies on the whole picture, there are 12 of them in total standing for the 12 peaks among the Wu Mountains.Turn to look the figures at the bottom; the leading character is a young lady together with a fairy.The flowers and fruits symbolize the sweet love and the happy ideals.Meanwhile, the plant, animals, and fishes in the background are telling the environment of the Three gorges.The figure of the Easter Pearl Tower, the Shanghai Port, and the buildings in the bund areas signify the contribution that this project will make for the region along the mid and the down stream of the Yangtze.Additionally, some other figures are also show in the picture like the fairies playing music, dance of the Ba People, the thousand-hands Kwan-yin, and etc. Echoing with the figures in the front, the central emboment in the back is the legendary that the magic bull helped Da Yu excavate the gorges.On both of the tow sides, there are the paintings of the gorges and the waters.In the gorges, there is an ancient picture showing the poor boatman, the boat trackers, and the people plunged into an aby of misery, which tell you the worst living condition of the people in the Three Gorges region in ancient times.On two sides, there are the sun, the moon, the Polaris, and the Big Dipper, composing a small celestial body.The flowing water splashing on the gra links together the figure of the whole emboment to show the strong culture connotation of the union of the space, the earth, and the human. Sightseeing Platform on Tanzi Ling坛子岭观景台 Here we are the sightseeing platform at the top of the Tanzi Ling, and here is the best place to view the entire construction site.Firstly, we ca see the main dam, where was former main navigation route.And next to the south bank is the 3 phase site of the Three Gorges Project, where will set the right bank generation stations.Please look at the further city at the mountainside of the opposite bank, its the new city of Zigui County.The reserved water has submerged the old city.And national government chose the mountainside as the new city site, and kept 30 thousand immigrants from places below the 175-meter water level.And look to the downstream, you will find the entire construction of the permanent ship lock.So here is the place “when standing at the top summit, we will see how small the surroundings are”. 185 Sightseeing Stand The so called 185 sightseeing stand is the start place of the main dam, which got the name from its height of 185 m.Now we are here, and I will give you a brief introduction to this main dam. Firstly, please allow me to ask you a question: how many dams have been finished in the world? Maybe we all know there are too many, but no exact numbers.From the material aspect, all these dams can be sorted in two types: one is earth rockfill dam made from earth, grit and rocks; and the other is plaster dam made of rocks or concretes.And the Three Gorges Dam is the latter one. Before, we said this dam is concrete gravity dam, and now it belongs to plaster dam, why? Here plaster refers to bricklaying, tiling.And now the concrete has replaced bricks, with better reliability and operation. Although the section of this gravity dam is large enough for safety, it will also split off after a certain time for its high intensity.The cause is the adhesive of concrete dam, the cement.During the solidifying proce, the cement will release heat, especially in summer, this heat will cause high temperature; but the solidified dam will shrink and cool, if limited, the shrink will cause cracks.And large cracks are very dangerous for the concrete dam, so there must some cool measures for the concrete structure.The traditional measure was firstly from American.That is to add cool aggregate and ice while mixing the concrete and place water pipes inside the dam for water cool.As a result, the builders call this “Feed Ice and Water for Concrete Dam”. Sightseeing Stand at the Dam Top Ladies and gentlemen, please look down the dam, the extra water or flood will discharged by this discharge dam at the middle of the main dam.The discharge dam is 483 in length, consisting of 23 deep outlets, 22 overflows and 22 bottom outlets.The bottom outlets have been submerged since the first water reserve in June of 2003. Normally, the speed of the water column from the deep outlet can reach 110 km/h, even 120 km/h when eater level equals to 175 m.Looking at this high speed water, maybe everyone would worry about the down streams safety if the dam was destroyed in war. The Three Gorges Project is located at the center of China main land, with dam height of 185 m, and total reservoir capacity of 39.3 billion m3.It can effectively control the flood and contribute to the economy and social development.If war took place in China, the Project would be one of main targets.So during the construction period, engineers were well considering its security.As early as October of 1958, former Premier Zhou Enlai established rules for dam security in details: With location in the central china and giant body, the concrete gravity dam is strong enough for conventional arms except nuclear ones.However, there are certain measures in case of nuclear attack.Besides, approved by hundreds of model test, the downstream gorges and watercourse are long and bend enough to decrease the flow speed and power.And later, the water will flow into bill areas where speed and power are decreased again.Then the water will be controlled in safe. In case of emergency, most water in reservoir can be empted to prevent main dam from break. Damming Memorial Park The damming memory park is located in the right bank of the main dam, covering an area of 90,000 m2.Here will take you back to the great historical damming moment by site remains show, scene play, video illustration, and historical records etc. Before, Chairman Mao Zedong described the plan “To rebuild the steles, to remove the clouds among Wu Mountains, and make a lake among high gorges mountains”.And now, all these have come true.Following the steps of Da Yu, thousands of builders have dammed the Yangtze 3 times within 37 km in Xiling gorge, and succefully built 2 main dams.And now, all of us can even image the complex technology and hard constructi
