Embodiment Construction
[0023] In conjunction with the accompanying drawings, the description is as follows:
[0024] The structure of the water conservancy project in the present invention includes: a shaft type spillway 1, a bell mouth 2, a gradient section 3, a shaft 4, a shaft axis 5, a pressure slope section 6, an energy dissipation well 7, a water retreat tunnel 8, a water intake culvert 9, Water inlet 10, flap gate 11, rubber waterstop 12, ventilation pipe 13, water diversion branch tunnel 14, irrigation channel 15, gate 16 at the exit of water retreat tunnel, gate pier 17, gate hoist 18, bank slope bedrock 19 , earth-rock dam 20, reservoir area (upstream) 21, river course (downstream) 22.
[0025] exist figure 1 Among them, the new type of water conservancy facility composed of the water intake culvert 9 and the shaft type spillway 1 is located in the reservoir area (upstream) 21 . The backwater tunnel 8 of the new water conservancy facility does not pass through the earth-rock dam 20, but ...
