The diversion tunnel has a total length of 4623m and is a city-gate type pressureless tunnel. Its outlet is connected to the front pool of the hydropower station. The entrance gate section of the diversion tunnel is 6m long, the slope drop i = 1/1100, the net width is 5.40m, the design reference flow is 47.17m3 / s, the net height is 6.26m, and the top arch center angle is 120 °. The main contents of this construction organization design include the general layout of the construction, the construction schedule plan and the main plan construction, construction safety, civilization, environmental protection and quality and other guarantee measures. According to the project characteristics, structure and construction difficulty requirements, a practical construction plan is compiled. The general layout of the construction involves the layout of the material yard, mixing system, mechanical repair plant, etc. A reasonable spatial layout can effectively maximize the use of the site. The construction schedule mainly includes the arrangement of the entire plan and the specific construction steps of the tunnel. At the same time, measures to ensure the construction period must be made. The total construction period of the project is 2 years. The main project construction mainly involves rock excavation, borehole blasting, anchor-shotcrete support, etc. The optimal construction plan is selected according to the conditions of the tunnel.
