Flood discharging tunnel structure
The invention relates to a flood discharging tunnel structure, in particular to a flood discharging tunnel structure applied to the technical field of hydraulic and hydro-power engineering. The flood discharging tunnel structure is simple in structure and can effectively ensure stability and smoothness of water flow. The flood discharging tunnel structure comprises a water inlet tower, a pressure section, a non-pressure section, an underground gate working chamber, a falling tail and an outlet, the other end of the pressure section is connected with the non-pressure section, one end of the non-pressure section far away from the pressure section is connected with the falling tail, the underground gate working chamber is arranged on the non-pressure section, a bent section is arranged on the pressure section, and the outlet is formed in one end of the falling tail far away from the non-pressure section. As the pressure section and the non-pressure section on a longitudinal profile are of straight structures, the proportion of the length of the falling tail arranged at the tail of a whole flood discharging tunnel to the length of the whole tunnel is small, most of total hydraulic head pressure differences are concentrated on a falling tail section with a small proportion in the length of the whole tunnel by the structural form, the range of a high-flow-rate section is narrowed, air entrainment and cavitation prevention difficulty is reduced, and high-speed water flow problems can be solved in a centralized manner.
