Recently, a number of major water conservancy projects have ushered in new nodes

Let's look

Fendou Reservoir has passed the completion acceptance

Sometimes, Muling City, Heilongjiang Province organized a completion acceptance meeting for the completion acceptance of the Fendou Reservoir project. The acceptance committee and the experts attending the meeting viewed the on-site, listened to reports, and reviewed the information. After full discussion, they unanimously agreed that the Fendou Reservoir project passed the completion acceptance, marking the successful conclusion of the project.

Fendou Reservoir is one of the 172 major water conservancy projects determined by the State Council. It is a large (2) type water conservancy hub that focuses on water supply, takes into account flood control, and combines comprehensive utilization of irrigation, power generation, etc. The main buildings include river dams, overflow dams, power stations and fish paths. The total reservoir capacity is 191 million cubic meters, which can provide urban water supply to the downstream every year 53.14 million cubic meters, irrigation compensation water supply of 9.68 million cubic meters, and irrigation area of ​​112,000 mu is added and improved.

The water irrigation area project was approved for project approval

On January 27, the feasibility study report on the water irrigation area project in Hunan Province was approved by the Provincial Development and Reform Commission, marking that the project was completed and entered the implementation preparation stage.

The water irrigation area project is a newly built large-scale irrigation area project defined in the "Comprehensive Plan for the Yangtze River Basin" and the "Comprehensive Plan for the Yuanjiang River Basin". It is a major water conservancy project arranged by the Hunan Provincial Government and the Ministry of Water Resources to focus on promoting the preliminary work this year. The project is located in the central area of ​​Huaihua City, and the irrigation area is mainly located on both sides of the tributary of the Yuanjiang River and the right bank of Chenshui. After the project is completed, it can meet the irrigation needs of 617,300 mu of arable gardens in central Huaihua, and improve the water supply guarantee capacity of 172,000 people in Hecheng District, Zhongfang County urban district and 13 townships in the irrigation area.

The construction of Dongzhuang Water Conservancy Hub Project is accelerated

Dongzhuang Water Conservancy Hub Project is one of the 172 major water conservancy projects for water conservation and water supply identified by the State Council. This project is also an important flood control backbone project and large-scale water source project in the "Flood Control Plan for the Yellow River Basin" approved by the State Council and the "Guanzhong-Tianshui Economic Zone Development Plan" approved by the National Development and Reform Commission.

On February 2, at the construction site of Dongzhuang Water Conservancy Hub, construction workers were tied up steel bars

On February 2, when they walked into the construction site of Dongzhuang Water Conservancy Hub, large machinery shuttled back and forth, and more than 100 construction workers stayed at the construction site. In order to ensure the construction task node, this year's Spring Festival, the construction site did not stop work, and the project construction showed a scene of sprinting and hard work.

After the Dongzhuang Water Conservancy Hub Project, the daily flow of the year is greater than the ecological base flow by 5.33 cubic meters per second, ensuring continuous flow in the lower reaches of the Jing River and the Jingwei Wetland does not shrink or degrade, which plays an important role in improving the river ecological environment during fish breeding and the river ecological environment during the downstream flood season. The 97-kilometer-long water surface formed in the reservoir area with an area of ​​73,000 mu will greatly improve the ecological environment of the Jingwei River Basin. After 50 years of operation, the project can reduce the silt into the Wei River by 3.051 billion tons, reduce the silt into the Wei River by 657 million tons, reduce the cumulative silt thickness of the lower reaches of the Wei River from 2.6 meters to 0.76 meters, and maintain the standard for flood defense of the embankment in the lower reaches of the Wei River for at least 38 years. It can reduce the silt into the Yellow River by about 2.5 billion tons, reduce the silt accumulation of the lower reaches of the Yellow River by about 1 billion tons, and reduce the silt reduction benefits.

The Dongzhuang Water Conservancy Hub Project has increased the flood control standards in the lower reaches of the Jing River from once in 10 years to once in 20 years, ensuring the flood control safety of nearly 1.5 million people and 800,000 mu of arable land in three cities, Xianyang and Weinan.

The Huatanzi Reservoir Project is accelerating the progress

During the Spring Festival, at the construction site of the Huatanzi Reservoir Project, there were constant roars of machinery. The builders actively seized the golden period of the construction of the river dry season, scattered at different construction points, and carried out intense and orderly excavation of the left and right dam shoulders of the dam and debugging and improvement of the concrete mixing station to ensure that the dam pouring project can be carried out smoothly next year and the orderly advancement of the entire project.

At present, the "three connections and one leveling" and diversion tunnel projects of the Huatanzi project have been basically completed, the right bank traffic tunnel has officially opened to traffic, and the diversion tunnel has met the conditions for overcurrent. The renovation and expansion of the 532 county road has been completed, and the main project has been excavated on two steps on the left and right dam shoulders. The mixing station in the main hub construction area has completed 80% of infrastructure construction and 70% of equipment installation, and the project is progressing steadily.

The Huatanzi Reservoir Project is one of the 150 major water conservancy projects in the country with a construction period of 45 months. After the project is completed, the production and living water problems of 337,300 people in the central urban area of ​​Sinan County and surrounding rural areas, as well as 50,100 mu of continuous irrigation areas such as Sinan County’s provincial industrial park and Tangtou Bazi will be effectively solved.
