Overflow dam flood discharge underflow flushing preventing energy dissipation wall
The invention discloses an overflow dam flood discharge underflow flushing preventing energy dissipation wall. A falling sill stilling pool is arranged on the bottom of an overflow dam main body flooddischarge channel. An energy dissipation wall body is arranged at the far end. A composite permeable energy dissipation wall fixed into a bottom layer is arranged in an area between the stilling pooland the far end energy dissipation wall body, or a front end area of the stilling pool or a front end area of the far end energy dissipation wall body. According to the overflow dam flood discharge underflow flushing preventing energy dissipation wall, the composite permeable energy dissipation wall is arranged in the area between the stilling pool and the far end energy dissipation wall body, inthe energy dissipation process, some discharged water is subjected to friction, rotary rolling, dispersing and colliding, and changes into heat energy to be dissipated. When the composite energy dissipation wall is built before the stilling pool, flushing and wearing to an original stilling pool by high-speed water flow can be reduced to the great extent.
本发明公开了一种溢流坝泄洪底流防冲刷消能墙，溢流坝主体泄洪通道底有跌坎消力池，远端有消能墙，消力池与远端消能墙之间的区域或消力池的前端区域或远端消能墙的前端区域，有固定于底层内的复合透水消能墙。本发明复合透水消能墙置于消力池与远端消能墙之间的区域，消能过程主要使一部分泄水通过摩擦、旋滚、扩散、撞击、变成热能耗散。将该复合消能墙修筑于消力池前时，能够极大程度上减少高速水流对原有消力池的冲刷和磨损。
