To achieve these goals, the utility model adopts following technical scheme: a kind of flood discharging tunnel that adopts " dragon sticks up tail " pattern to reconstruct by Diversion Tunnel, it is characterized in that, comprising: intake tower, Diversion Tunnel, vertical shaft section, flat bank section and lock chamber section and downstream energy dissipating section; Described intake tower is communicated with the Diversion Tunnel front end, Diversion Tunnel adapter section afterbody connects the vertical shaft section, vertical shaft section upper end is communicated with flat bank section front end, and vertical shaft section lower end is communicated with the hole body of Diversion Tunnel, and described flat bank section end is provided with lock chamber section and downstream energy dissipating section.
Described Diversion Tunnel end is provided with the block section.
Described intake tower is provided with the later stage water inlet.
Be provided with cone valve in the described block section.
Described flat bank section connects the diameter of the turning radius at vertical shaft section place greater than 5 times of Diversion Tunnels.
Described flat bank section outlet crossfades into square cross-section by round section.
Compared with prior art, the utlity model has following advantage:
(1) the hole inner structure is simple: because Service gate is positioned at the tunnel outlet, therefore, the above tunnel of runtime gate is pressurized tunnel, therefore, can require Diversion Tunnel once to build up and press circle according to operation condition, the cavitation erosion problem that high-velocity flow brings does not exist substantially, and the hole inner structure is simple, and construction technology is operated easily;
The all corresponding reduction of intractability of structure problems such as (2) the stressed improvement of Service gate: through after the vertical shaft section, upper pond level reduces with outlet base plate head difference, and hydraulics, gate are stressed;
(3) Dissipation of Energy solves easily: same, because the existence of vertical shaft section, upper pond level significantly reduces with outlet base plate head difference, even there are problems such as cavitation erosion in the energy dissipater, because outside the hole, the maintenance condition is good, the downstream Dissipation of Energy solves easily.
