Vertical shaft rotational flow flood discharge tunnel
The invention discloses a vertical shaft rotational flow flood discharge tunnel, The vertical shaft rotational flow flood discharge tunnel comprises an inlet lock chamber section, an upper adit section, a volute chamber connecting section, a volute chamber, a vertical shaft and a lower adit section which are sequentially connected, wherein the bottom end of the volute chamber is connected with the vertical shaft through a transition section, a stilling well is arranged at the bottom end of the vertical shaft, and the lower part of the side wall of the vertical shaft is connected with the lower adit section through a connecting section; a flow dividing pier is arranged on a bottom plate of the volute chamber connecting section, and a flow guiding ridge is arranged on the inner side of the volute chamber. According to the vertical shaft rotational flow flood discharge tunnel, the regular water flow state, smooth ventilation and sufficient energy dissipation of the volute chamber of the vertical shaft rotational flow flood discharge tunnel can be achieved, meanwhile, the height of the volute chamber can be reduced, and safe operation of the high-water-head and large-flow vertical shaft rotational flow flood discharge tunnel is guaranteed.
本发明提供一种竖井旋流泄洪洞，包括依次连接的进口闸室段、上平洞段、涡室连接段、涡室、竖井和下平洞段，所述的涡室的底端通过渐变段与竖井连接，竖井的底端设置有消力井，竖井的侧壁下部通过衔接段与下平洞段连接；所述的涡室连接段的底板上设置有分流墩，所述的涡室的内侧设置有导流坎。本发明竖井旋流泄洪洞，能够实现竖井旋流泄洪洞涡室水流流态规整、通气顺畅、消能充分，同时还可降低涡室高度，保证高水头、大流量竖井旋流泄洪洞安全运行。
