The utility model relates to a 200 superelevation dam reservoir unloading hole more than rice, including setting up the unloading hole body in the massif, the unloading hole body has the water inlet that is located the reservoir bottom of the reservior to and the delivery port that is linked together with the river course that is located low reaches, and set up at the internal unloading gate in unloading hole, the unloading hole body is " U " shape of inversion, the elevation of water inlet is higher than the elevation of delivery port, the unloading gate is located the downstream side at unloading hole body top. The 200 superelevation dam reservoir unloading hole more than rice who obtains has effectively reduced the water pressure that the unloading gate bore, has solved the unloading problem of superelevation dam reservoir more than 200 meters under current gate technical conditions. |
