Li Bing and his son with building water conservancy projects of the great achievements of the long history of admiration and Dujiangyan, and pure natural beauty, We 2008-2-11 Huayang starting from 8 am, 1 hour 35 minutes arrived. To the door that want to stop parking costs 10 yuan, which is not Kengren Well, but these people do not think they are the way to make money through this Kengren can do, there is no rational to him. but we parked the car after he said something that made me laugh and cry, then: So far, the age of the oldest, the only retention, diversion dam is characterized by a non-ambitious water conservancy project. childhood had heard the story of Li Bing and his son built the Dujiangyan, is great, but how to build the weir, how diversion, something a little on the detailed can not be said here. in college who studied fluid mechanics,UGG boots, inkling that the principles of fluid motion. In the face of Dujiangyan, Li Bing and his son then I can not imagine how to calculate how this works, how to locate the open pass drainage areas. The more we do not know, the more can not imagine, the more incredible, more Chinese people can feel the wisdom and experience the ancient civilization of the great flood for the greatest feat of human pride. Do not wordy, up to see how she scientific solution automatically divert the river, automatic flushing, control water flow problems, eliminate the flooding, the western Sichuan Plain into a it.
we are away from the reactor from the door into the park, the quiet jungle, always make people linger. First of all to visit the Heritage Museum Dujiangyan, which a large number of historical data on the Dujiangyan Irrigation Project to deepen the understanding of Guyan, by the way look at the stone hall. and then go forty-two (the number of my dad) is located steps away from the heap of Fulong, we see that the right of a monument ,Discount UGG boots, that is Yu Leishan, Li Bing was the construction of Dujiangyan Irrigation Project, the first opening Yu Leishan, soil separation Jiang Yu Leishan open here, forming an isolated hill heap, this is the origin from the heap.
Fulong Front Hall, dedicated the statue of Li Bing. It is said that when the gate is in the construction of river bed in the back again. because of stone lying in the river, the text clearly visible chest. the middle of the text: ice shoulder to ensure that only benefit the people of Minjiang River. in the rear left open at a pavilion, the name I saw green water in the swing Neijiang. Why is it green? - because the color depth of the refraction presented.
here you can see the most spectacular treasure bottle
Baopingkou the level and flow with the river Jihuan automatically adjust the amount of water, like the same bottle, and strictly control the flow of river water into the Chengdu Plain, when the treasure bottle of water into the saturated (about 700 cubic meters / second), no matter how much flooding occurred Minjiang River, Po bottle also refused the shown the level of water science in ancient China, are not worthy of you whom we are proud!
add Baopingkou origin: As early as 2000 years ago the state of Qin, no gunpowder, and the use of iron are more backward, and this is a picture-Yu Leishan and rock (conglomerate sedimentary rock), the structure is very strong, indeed the gap to be excavated is not easy to do. I think of the use of burning rock, so hot, then water vinegar. chisel to the floor, and then burn a layer, repeat the procedure, and finally, after eight years, opened a wide-m 20M, high-40M, 80M long gap, this hole in the Yu Leishan split off from the reactor, also built a treasure bottle.
we shake down the bridge into the sandstorm weir. My parents went up a sweat scared ah!
Feisha weir is Dujiangyan The second main water conservancy project, which weir repair the side away from the reactor is a low dam, crest is only 2.15 meters away from the river. Its main function is to Neijiang flood sediment. from the fish within the river divided into the , was from the heap a natural swirl together, when summer and fall quarter bottle of water flow can be greater than the flow of treasure, the treasure can not bottle the water, the main escape from the sandstorm weir, and swirl the pan- windblown sand in the sediment from the weir together from the outflow will go. . flood, from the fish head points into the flow of the main channel Neijiang up to four times the flow of treasure bottle .75% of the river can escape from here. When the dry season, water level lower than the Feisha weir, it has become a natural sluice, flood discharge automatically lose the function of irrigation to ensure the Chengdu Plain. Data also showed that the second use of the weir in the corner Feisha fluid mechanics,UGGs, discharged about 15% of river sediment. fish head is 80% of sediment, the flow of sediment on the Chengdu Plain water only about 5%. The next figure I'm from the West Tea Horse Road taken off.
