#miniconstruction #mrconstruction #hydroelectric #hooverdam “ The Hoover Dam, formerly known as the Boulder Dam, is a concrete arch gravity dam in the Black Canyon of the Colorado River, on the border between the US states of Arizona and Nevada. It was built between 1931 and 1936 during the Great Depression. The stamping construction was the result of an enormous effort that involved thousands of workers, and took over 100 lives. The dam was officially named Hoover Dam after a 1947 Congressional resolution. However, this dam is believed to have severely affected the ecosystem in the lower Colorado River area, causing the Colorado River Delta to dry out and shrink significantly. The Colorado River is vast with a length of 2,333 km, providing water for irrigation for 1/12 of the US land. The river begins at the headwaters of the upper Rocheuses mountain range toward the southwest, crosses the Colorado River, Utah and flows through a large ravine, flows into the state of New Mexico before emptying into the Gulf of California, forming the border river between Arizona and Nevada. , Arizona and California. The Colorado River is a “fierce“ river. In 1905, it suddenly changed course completely, forming Lake Sorton, 77 square kilometers, threatening to sink the California Inpiril River bed. To control and improve watering conditions, and use it for electricity generation, the authorities decided to build a large dam in the section of the river bordering Arizona and Nevada. In 1928, Congress issued money, and construction began in 1931. President at that time Herbert Hoover was very interested in this project, decided to name it Hoover Dam. Construction was completed in 1936, but President Roosevelt called it Boulder Dam. This name was used until 1947, after which the parliament restored the old name. To build this dam, people had to excavate 8.2 million tons of lava, with the same amount of steel used to build the Empire State Building. The base of the dam is 201 m thick, 221 m high, close to the height of a 70-storey building. Leaning close to the north of the dam has become Lake Mead, one of the largest man-made water reservoirs in the world, with an irregular sawtooth shape, 177 km long, the lake shoreline is 1,323 km long. To the north of Lake Mead is a 14,165-hectare red sandstone national park. The sandstone here is gradually turning from red like fire to light purple. Rain and wind erosion, sandstone carved into round parasols, honeycombs and unique strange shapes, like the head and trunk of a great elephant. About 4,000 people were involved in the construction of the Hoover Dam. Hoover is located in the town of Borde, a lovely, pleasant village, with all the features of both city and country. “ If you like the video, please like, share, comment and subscribe to my channel to support me Thanks for watching!
