With the cordial care and strong support of the Ministry of Water Resources, Heilongjiang Province and Inner Mongolia Autonomous Region governments at all levels, and with the joint efforts of all contractors, the river was successfully intercepted on 200118. By the end of August, 2003, all preparations for external traffic roads, traffic bridges under the dam, sand and gravel mining and processing, concrete mixing, first-stage diversion, substation construction, material transfer station and building construction have been completed. The construction of main dam, powerhouse, spillway, left and right auxiliary dams, irrigation tunnel and other projects and resettlement work were carried out in an orderly and intense manner as planned, and the construction period, quality and investment were effectively controlled. The accumulated investment is nearly 2.368 billion yuan.

The revised estimated total investment is 7.659 billion yuan, including 2.872 billion yuan for hub project, 4.68/kloc-0.0 billion yuan for reservoir inundation treatment, 46.34 million yuan for soil and water conservation project, 23.65438+0.00 million yuan for environmental protection project and 37.38 million yuan for power station delivery project.

The construction diversion adopts two stages, the first stage is the left bank open channel diversion, and the second stage is the temporary bottom hole diversion in the dam section between the powerhouse installation. 200 1 1 .8 realized the first-stage interception, in September 2004 15 realized the second-stage interception, in September 200511closed the floodgates, and in July 20061.

Mainly completed quantities: earthwork excavation of 6.098 million m3; Earth and stone filling 965438+670000 m3; Concrete pouring is 6.5438+0.04 million m3; 32,500 cubic meters of asphalt concrete; Manufacture and installation of 7000t hydraulic metal structure; Install 19 sets of lifting equipment; Install 4 hydro-generator sets; Install 2 sets of main substation equipment.

The main project is divided into 8 unit projects, 124 sub-projects and 33,383 unit projects. After acceptance by Songliao Water Conservancy Commission, 7 units are excellent, with the qualified rate of 100% and the excellent rate of 87.5%. Excellent subdivisional work 108, qualified rate 100%, excellent rate 87.1%; There are 278 excellent unit projects16, with a qualified rate of 100% and an excellent rate of 83.3%. The land requisition and resettlement work of Nierji Reservoir is led by the provincial (district) government, implemented by the county (city, banner) government, managed by the owners and guided by the Ministry of Water Resources. The construction unit is mainly responsible for the coordination, schedule control and plan management of land acquisition and demolition, as well as the supervision, inspection and guidance of immigration supervision.

200 1 By the end of 2006, all the immigrants below the relocation line of 2 17m in the reservoir area had moved out of the reservoir area, and the bottom cleaning and acceptance of the reservoir had been completed, which met the operation requirements of the project for water storage and power generation. There are 72 new resettlement sites in the reservoir area, and the actual relocation and resettlement 14980 households with 556 16 people, including 9667 households with 35 150 people in Heilongjiang Province and 53 13 households with 20466 people in Inner Mongolia. * * * Newly-built Xincun road is 329. 1 7km, water supply pipeline is 388.94km, and special works in the reservoir area: traffic road is 324.67km, power supply line (10kV) is 501.74km, and telecommunication line is 287.73km. In addition, in 2007, In the process of project preparation and construction, establish a joint meeting system of competent ministers, governors and chairmen of autonomous regions, give full play to government functions and coordinate and solve major problems in project preparation and construction. The joint meeting was convened by the Ministry of Water Resources, and Songliao Water Conservancy Commission was the office of the joint meeting. In accordance with the requirements of the reform of the management system of water conservancy project construction, with the approval of the Ministry of Water Resources, Songliao Committee, Heilongjiang Province and Inner Mongolia Autonomous Region jointly established Nenjiang Nierji Water Conservancy and Hydropower Co., Ltd. to be responsible for the construction and operation management after the completion of the project. The company has a board of directors, a board of supervisors, a general manager, three supervisors and several middle management departments (7 offices during the construction period, currently 1 1 offices).

In the process of project construction, the "four systems" were strictly implemented, which effectively controlled the project quality, progress, funds and safety. Since the impoundment of the reservoir in September 2005, it has brought great social and economic benefits. Before power generation, in the Songhua River pollution incident in June 5438+065438+ 10, 2005, according to the dispatching instructions of the State General Administration of Defense and Songliao Committee,1diluted water volume from October 22nd to February 22nd/1100 million m3,1*. In the spring drought in 2006, at the request of the Water Resources Department of Heilongjiang Province and the Qiqihar Municipal Government, 405 million m3 of water was supplied to the downstream, which effectively solved the urgent need for agricultural and environmental water. From April/KLOC-0 to the end of July, 2007, the reservoir continuously discharged water, which compensated the downstream water supply by nearly 900 million m3, greatly alleviating the drought in Northeast China. In addition, from July 2006 16, when the first unit was connected to the grid to May 2007 1 1, the power plant has achieved 300 days of safe production, generating 34 1 10,000 kwh.

With the establishment of a reservoir management and development company, a reservoir tourism company and a reservoir hotel and the corresponding commercial operation, the diversification of reservoirs has begun.
