Novel water flow opposed impact type drop building
The invention discloses a novel water flow opposed impact type drop building. The drop building comprises a channel I; the channel I is sequentially communicated with a stilling pool and a channel II;a drop sill is arranged between the channel I and the stilling pool; a drop well inlet is formed in the bottom of the channel I; a drop well outlet is formed in the bottom of the stilling pool; and adrop well pipe is arranged between the drop well inlet and the drop well outlet. The drop well pipe is communicated with the channel I and the stilling pool. On the basis of an original drop building, the drop well inlet is formed in front of the water dropping drop sill, the drop well outlet is formed in the stilling pool, a drop well in front of the drop sill can divide channel flow and reduceunit width flow of a drop water notch, water flow at the drop well outlet and a water tongue falling from the drop sill form opposed impact energy dissipation, and the scale of an energy dissipater can be reduced, so that the energy dissipation effect is improved through water flow impact, friction and air entrainment.
本发明公开了一种新型水流对冲式跌水建筑物，包括有渠道Ⅰ，渠道依次连通有消力池及渠道Ⅱ，渠道Ⅰ与消力池之间设置有跌坎，渠道Ⅰ底部开有跌井进口，消力池底部开有跌井出口，跌井进口与跌井出口之间设置有跌井管，跌井管连通渠道Ⅰ与消力池。本发明在原有的跌水建筑物的基础上，在跌水的跌坎前设置跌井入口，出口设置在消力池内，跌坎前的跌井可对渠道流量进行分流，减小跌水缺口的单宽流量，跌井出口的水流与跌坎跌下来的水舌形成对冲消能，可减小消能工规模。使水流能够互相对冲，利用水流冲击、摩擦、掺气增加消能效果。
