The Pangduo Water Control Project in Tibet

On July 5, 2009, the Pangduo Water Control Project in Tibet started in Pangduo Township, Linzhou County.

On September 6, 20 10, the diversion tunnel, one of the important nodes of the Pangduo Water Control Project in Tibet, was successfully connected, which achieved another important stage project goal of the project and also marked that the dam construction of Pangduo Water Control Project entered the expressway from now on.

20 10 10No. 1 1, the construction of the cutoff wall of the Pangduo Water Control Project in Tibet was completed. This is also the deepest cutoff wall project in the world, with the deepest wall depth of 158.47 meters, which is 22 meters deeper than the previous cutoff wall of Tokyo Bay Bridge in Japan. The dam foundation seepage control design of Pangduo Multipurpose Dam Project adopts totally enclosed scheme, the dam depth is 65438 0.20m, and there are three rows of grouting curtains under the concrete cutoff wall. The total length of cutoff wall axis is1.073m, and the final depth of wall groove will reach1.55m..

201011kloc-0/1,the asphalt concrete paving test was carried out in the Pangduo water control project. The test content includes the preparation technology of asphalt concrete in cold and high altitude areas and the key technology of asphalt concrete core wall construction in cold and high altitude areas. The first application of roller compacted asphalt concrete core wall technology in Tibet water conservancy project. The experimental research and achievements of this technology are of great significance to ensure the safety of reservoir dam construction and operation management and prolong the service life of water conservancy projects.

On 20 11June1day, the groundbreaking ceremony for the irrigation and water conveyance tunnel project of Pangduo Water Control Project was held at the construction site.

On July 36, 20 1 1, the main project of Pangduo Water Control Project in Tibet began to fill the asphalt concrete core wall of the dam, which is the key and core part of the dam seepage control effect, marking a new stage of the project construction and laying a solid foundation for the smooth closure of the dam in June 1.

On August 25th, 20 1 1, the relocation and resettlement of people in the reservoir area of Pangduo Water Control Project in Tibet was successfully completed. The relocation and resettlement of migrants in the reservoir area of Pangduo Water Control Project is the largest and largest construction project in our region so far.

From 2011September 14 to June 15, the land-expropriated migrants of Pangduo Water Control Project in Tibet successfully passed the special acceptance. The land requisition and resettlement work of Pangduo Water Control Project in Tibet was carried out in an orderly manner according to the construction progress and plan. During the river closure stage, the land requisition is completed, the resettlement is properly completed, and the cleaning of the reservoir bottom is basically completed, which can meet the relevant national regulations and meet the project closure.

From 2011 10 to 9/0110, the Yangtze River Water Resources Commission and Xizang Autonomous Region Water Resources Department hosted an acceptance meeting for the closure stage of the Pangduo Water Control Project in Sichuan. In order to make all the preparations before the completion and acceptance of Pangduo Water Control Project, at the invitation of Pangduo Water Control Project Administration of Xizang Autonomous Region, the Yangtze River Water Conservancy Commission of the Ministry of Water Resources and the Water Resources Department of Xizang Autonomous Region formed an expert group. On August 29th and 30th, 20 1 1, the expert group conducted in-depth on-site inspection on the project construction and resettlement of immigrants, and put forward expert opinions. From June 10 to June 10, the members of the acceptance committee watched the project video materials, listened to the reports of the project legal person, design, supervision, construction and quality and safety supervision, and carefully consulted the relevant acceptance materials. After full discussion, they formed an acceptance certificate for the closure stage of the Pangduo Water Control Project in Tibet, believing that there are many projects near Tibet.

The Pangduo Water Control Project, which is known as the "Three Gorges in Tibet", has entered a climax at present, and it is planned to complete the first unit operation and power generation in June+10 this year. In order to achieve this goal, the officers and men of several project departments next to the tenth detachment of the Armed Police Hydropower Station who undertook the project worked overtime and devoted themselves to the construction activities.

The market researcher of China Industrial Insight Network saw that the construction site was a busy scene, and all construction units overcame the difficulties of cold and lack of oxygen, high technical requirements for construction, and the power of equipment was only half that of the mainland, and fought day and night on the construction site.

Jiang Yi, political commissar of the multi-project department next to the 10th detachment of the Armed Police Hydropower Station, said that since the project started in 2008, the construction personnel of the project department have been working 24 hours a day. At present, the overall progress of the project is smooth, and some projects have been completed over schedule.

In May, the Pangduo Water Control Project in Tibet approached the flood season. In order to make every effort to ensure the safety of the project during the flood season, officers and men of Pangduo Project Department also conducted a 15-day dam-building drill in combination with the actual construction.

Jiang Yi said that this drill was the first time that the project department took the actual soldiers as the front finger and opened up a new tactic of "high-intensity excavation, saturated transportation and layer-by-layer rolling" in engineering construction. During the drill, the high-definition camera and 3G image transmission system were used for real-time transmission, which realized the real-time command and monitoring of the construction site by the corps and grass-roots command posts, and ensured the flexibility of the troops.

Pangduo Water Control Project is one of the 23 start-up projects determined by the state on the occasion of the anniversary of the western development 10, and it is the largest investment water control project since the peaceful liberation of Tibet. With a total investment of 4.569 billion yuan, the project is a large-scale water control project focusing on irrigation and power generation, taking into account flood control and water supply.
