The construction of the Xianghe Water Conservancy Hub and Irrigation District Project Construction steadily advanced

Recently, the Tibet Xianghe Water Conservancy Project has laid the foundation for the water storage of the lower gate through water storage safety appraisal, and also created conditions for achieving the first unit power generation target in 2022.

The Tibet Xianghe Water Conservancy Hub and the supporting irrigation zone project are one of the 172 major water -saving water supply projects determined by the State Council. It is the key backbone project of the "13th Five -Year Plan" plan for the Water Conservancy Reform and Development of the Tibet Autonomous Region. The environment is mainly based on the power generation. After the project is completed, the conditions for improving the irrigation of agriculture, animal husbandry and forestry, developing land and water resources, providing urban and rural living industrial water, improving the ecological environment of the national natural reserves of the black -necked crane in the middle of the Yajiang River, and promoting the effective connection between poverty alleviation and rural revitalization and effective connection. Important role.

On December 7, 2019, the diversion of the Xianghe Water Conservancy Project was connected

The Tibet Xianghe Water Conservancy Hub and supporting irrigation zone projects are located in Nantimelin County, Shigatse. The hub buildings are mainly composed of river dams, cave flooding roads, diversion flood caves, power generation water diversion systems, power stations, and fish roads. The normal water storage level of the reservoir is 4099 meters, the design flood is 4101.47 meters, and the school nuclear flood position is 4102.84 meters; the total reservoir capacity is 113.4 million cubic meters, and the Xingli reservoir capacity is 68.84 million cubic meters; At the time, the dam dam is asphalt concrete heart wall gravel dam, with a maximum dam height of 51 meters. The supporting irrigation area involved 124,900 mu of irrigation area, with an average water supply of 111 million cubic meters in many years. Total investment is 2.71 billion yuan (the total investment of the central project is 2.06 billion yuan).

On February 28, 2020, the Xianghe Water Conservancy Project successfully achieved the interception of the river

Since the start of the construction on April 3, 2019, the participating units have overcome the difficulty of high -cold and oxygen and oxygen in the plateau at 4100 meters above sea level, the excavation of high -side slopes in the rainy season, winter construction, and continuous epidemic. Don't be afraid of suffering and higher levels of altitude, rush progress, quality, strong safety, implement various water and environmental protection measures, inverted construction periods and linked chart operations, successfully completed the "Decele of February 28, 2020" "2020" 820 On the 22nd, the target task of important node target tasks such as "" "Filling to the top" such as "" November 22, 2021 "" November 22, 2021 ". Since the beginning of this year, the construction of the Xianghe Water Conservancy Hub in Tibet and the irrigation zone project has been steadily advanced. At the end of May this year, the project of the Xianghe Water Conservancy Project reached the image of the lower gate.

On August 22, 2020, the construction of the anti -seepage wall of the dam -based concrete was completed, up to 139 meters

In order to ensure the scientificity and planning of the implementation of the project construction organization, the participating units analyzed the project characteristics, key points and difficulties based on the full research of the preliminary data and design reports of the project, proposed reasonable planning and deployment opinions, clarified the key line of the project project And key tasks, achieve "planning first and technology" in various tasks. At the same time, it boldly put forward optimization suggestions, and proposed optimization solutions such as increasing construction branches and upstream coffee wealth walls to inclined walls, early construction anti -seepage walls, and channel wheel irrigation full irrigation, which promoted the smooth development of the project.
