Deep hole arrangement structure for flood discharge and energy dissipation of high arch dam
The invention discloses a deep hole arrangement structure for flood discharge and energy dissipation of a high arch dam, and belongs to the technical field of water conservancy and hydropower, the deep hole arrangement structure comprises a high arch dam deep hole group and a surface hole group, the high arch dam deep hole group comprises 5-7 flood discharge deep holes, and the arrangement form of the flood discharge deep holes is as follows: the outlet cantilever angle of the flood discharge deep hole at the middle position adopts depression angle type arrangement; the angle of the outlet cantilever angle is-5 to-2 degrees; the surface hole group comprises 4-6 flood discharge surface holes, and the flood discharge surface holes and the flood discharge deep holes are arranged in a staggered mode. The problem that nappes rushed out of deep holes in a depression angle mode on the two sides impact the inner side of the side wall of the plunge pool is effectively solved.
本发明公开了一种高拱坝泄洪消能的深孔布置结构，属于水利水电技术领域，包括有高拱坝深孔群与表孔群，所述高拱坝深孔群包含有5～7个泄洪深孔，所述泄洪深孔布置形式为：居中位置泄洪深孔的出口挑角采用俯角型式布置，所述出口挑角的角度为‑5～‑2°；所述表孔群包含4～6个泄洪表孔，所述泄洪表孔与泄洪深孔交错布置；本发明有效解决了两侧深孔俯角型式冲出的水舌冲击水垫塘边壁内侧的问题。
