Experts predict that with the monitoring of fishery environment in Beijing, the disease is effectively controlled. The prevention and treatment of disease prevention and aquatic product safety projects, Beijing Aquatic Products (China Environmental News) mining technology reached international level Shanghai will build the world's largest diameter tunnel Shanghai will build a 15.2m diameter Chongming cross-river tunnel in the Yangtze River estuary, the tunnel will become The largest diameter tunnel in the world. This was revealed by relevant experts at the "Second and Three Shanghai International Tunnel Engineering Seminar" held recently at the Shanghai International Convention Center. It is reported that Chongming Island, which is located in the north of Shanghai, accounts for one-fifth of Shanghai's area. Due to the blockage of the Yangtze River, it has been separated from Shanghai for a long time. In the past few decades, the passenger ferry is the only way to enter and exit Chongming Island. With the new round of urban construction and economic development in Shanghai, the Chongming River Crossing Project, which aims to break through the “bottleneck†of this traffic, “surfacedâ€. Liu Jianhang, an academician of the Chinese Academy of Engineering and former chief engineer of the Shanghai Metro Corporation, said that Shanghai will start construction of the Chongming River Crossing Tunnel between Shanghai Pudong and Changxing Island. The diameter of the tunnel will reach 15.2m in 8kni, which will be built in the world tunnel. A new record has been set in history. At present, the world's largest diameter tunnel is a tunnel with a diameter of 4.87m built in the Netherlands. The underground excavator used in this project is the super large shield machine of the Bouygues company in France. Zhou Wenbo, general manager of Shanghai Tunnel Co., Ltd. revealed that the company has recently reached an agreement with Bouygues, France, to introduce a large-scale shield machine with a diameter of 14.87m to study and develop China's own super-large shield machine as soon as possible. He said that the "Shanghai Tunnel" has been expanded at the company's machinery factory in Shanghai Waigaoqiao, and is planned to be used for the processing of the 15.2m diameter shield machine. Academician Liu Jianhang said that after more than ten years of hard work, Shanghai has made creative development in the main method of tunnel excavation in underground tunnels. At present, Shanghai's shield excavation technology has reached the world advanced level. According to the relevant person in charge of the Shanghai Municipal Political Bureau, at present, the Chongming River Crossing Tunnel Project will start construction at the beginning of next year. The first wholesale electric motor unit of the Three Gorges Project was officially connected to the grid for power generation and commercial operation. At this point, all the six units of the first wholesale electric power of the Three Gorges Project have been put into operation. The Three Gorges Project has set a world record for the installation and commissioning of hydropower installations with a total installed capacity of 4.2 million kW and 6 sets of 700,000 kW in a year. The three hydropower generating units of the Three Gorges, which have all been put into production, can produce 3.52 million kW of electricity per hour. In the first year of commissioning, the actual power generation capacity of the first batch of the Three Gorges has exceeded that of Ertan Power Station and Gezhouba Power Station, making it the largest power station with the largest installed capacity and the highest power generation capacity in China. The No. 1 unit of the Three Gorges Project has a rated capacity of 700,000 kW. It is manufactured by the international multinational group VGS joint venture and is installed by the China National Hydropower Bureau. Installation time for Unit 1 was 175 days shorter than the first installed Unit 2. On July 10 this year, Unit 2 of the first generating unit of the Three Gorges was officially connected to the grid, and units 5, 3, 6, 4, and 1 were subsequently put into operation. According to reports, this year's Three Gorges Project power generation plan has been adjusted from the original 5 billion kWh to 6.13 billion kWh. As of 8:00 am on November 22, the cumulative power generation has reached 5.33 billion. ZHEJIANG FULE MINING MACHINERY CO., LTD , https://www.flmachines.com
