Double-Ogee curve type bottom aeration facility for inhibiting cavity backwater
The invention provides a double-Ogee curve type bottom aeration facility for inhibiting cavity backwater. The double-Ogee curve type bottom aeration facility for inhibiting the cavity backwater comprises an Ogee curve aeration ridge, an Ogee curve type backwater retaining plate, vent shafts, a vent channel and a vent window. The Ogee curve aeration ridge is connected with the straight line sectionof the upstream gentle slope of a release structure. One end of the Ogee curve type backwater retaining plate is connected with the bottom of the downstream end surface of the Ogee curve aeration ridge, the other end of the Ogee curve type backwater retaining plate is connected with the straight line section of the downstream steep slope of the release structure, the vent shafts are separately arranged on two sides of two walls of the release structure and close to the connecting position of the Ogee curve aeration ridge and the Ogee curve type backwater retaining plate, and the vent channelis arranged at the position, close to the downstream end of the Ogee curve aeration ridge, of the lower part of the bottom plate, penetrates through the release structure transversely and communicateswith the two vent shafts. The vent window is arranged on the downstream end surface of the Ogee curve aeration ridge and communicates with the vent channel, and the position, located on the downstream end surface of the Ogee curve aeration ridge, of the lower part of the vent window forms a water-retaining sill.
本发明所述抑制空腔回水的双渥奇曲线型底部掺气设施，包括渥奇曲线掺气挑坎、渥奇曲线型挡回水板、通气竖井、通气道和通气窗，所述渥奇曲线掺气挑坎与泄水建筑物的上游缓坡直线段衔接，所述渥奇曲线型挡回水板的一端与渥奇曲线掺气挑坎的下游端端面底部衔接，另一端与泄水建筑物的下游陡坡直线段衔接，所述通气竖井为两个，分别设置在泄水建筑物两边墙的外侧并靠近渥奇曲线掺气挑坎与渥奇曲线型挡回水板的衔接处，所述通气道位于靠近渥奇曲线掺气挑坎下游端的底板之下并横向贯穿泄水建筑物与两通气竖井相通，所述通气窗设置在渥奇曲线掺气挑坎下游端端面上并与通气道连通，通气窗之下的渥奇曲线掺气挑坎下游端端面形成挡水坎。
