Construction of a reservoir reinforcement project Planning and design
The reservoir project is located in the xx Tu plateau area in the middle and lower reaches of xx River, a tributary of Jing River in the xx River basin, near xx Village, xx City, xx Province, 19 km away from xx City. The project is connected to xx City by a special highway, which is convenient for external traffic. There is a 10000 kV transmission line from the construction site to xx city, and two hydropower stations with a total capacity of 1.484MW have been built on the construction site, which can supply power for construction. It is considered to set a 2 × 400m3 pool at the top of the left hilltop for centralized water supply by water pipes, and the water source is extracted from the tailwater of the power house. The quality and performance of Jiulianshan brand cement produced by Huanxian Cement Plant of xx City are relatively reliable, and the production scale meets the needs of the project; The cement plant is 280km away from the construction site. Other building materials such as steel, wood and oil can be purchased from local building materials and oil companies, and the steel should be reliable in quality and stable in performance. In this preliminary design, the hydraulic layout of the danger removal and reinforcement project of xxx reservoir has two schemes, Scheme 7 and Scheme 8. Scheme 8: The spillway has two holes, and the original dam crest is increased by 1.87m; Scheme 7: The spillway has three holes, and the original dam is not heightened. The excavation amount and concrete pouring amount of the spillway in Scheme 7 are much larger than those in Scheme 8, while the dam body filling amount in the dam heightening scheme is small, not the main work amount, and has little impact on the total investment.
