The invention discloses a tetrahedrons element pasted shrinkage type flip bucket for a low wall. The tetrahedrons element pasted shrinkage type flip bucket comprises discharge chute side walls and a discharge chute bottom plate, wherein the discharge chute side walls are connected to flip bucket side walls; the discharge chute bottom plate is connected to a flip bucket bottom plate; the flip bucket side walls adopt shrinkage type side walls for guiding water flow to the middle; a step-down floor is arranged on the middle part of the flip bucket bottom plate; tetrahedrons elements are arrangedat the two sides of the flip bucket side walls at the two sides; the bottom surfaces of the tetrahedrons elements are arranged on the flip bucket bottom plate; the back surfaces of the tetrahedrons elements tightly cling to the flip bucket side walls; the side surfaces of the tetrahedrons elements are vertically flush to the flip bucket side walls; and an upward inward two-way slope is formed on the front surfaces of the tetrahedrons element. According to the tetrahedrons element pasted shrinkage type flip bucket for the low wall disclosed by the invention, the tetrahedrons elements jack for guiding a water tongue to the upper part and the middle part of the flip bucket, enables high-speed discharged water flow to mutually extrude and collide to dissipate energy, guarantees space stretching and diffusing dissipated energy of the high-speed discharged water flow, reduces height of side walls, and guarantees structure stability. Meanwhile, diffusing type step-down floor embedded into base rocks is arranged on the middle of the flip bucket, so that stability of the flip bucket structure is improved, and water tongue flip is guaranteed.
本发明公开了一种矮边墙贴三角体收缩式挑坎，包括泄槽边墙和泄槽底板，所述泄槽边墙与挑坎边墙相接，所述泄槽底板与挑坎底板相接，其中挑坎边墙采用收缩式边墙，可将水流向中间导向；挑坎底板中部设置跌坎；两侧挑坎边墙处设置三角体，三角体底面坐落于挑坎底板上，背面紧贴着挑坎边墙，侧面与跌坎边墙上下平齐，正面形成一定的向上、向内的双向斜坡。该挑坎两侧收缩边墙处设置有三角体，通过三角体的顶托作用可以将水舌导向挑坎上部以及中部，可使高速下泄水流相互挤压、碰撞消能，保证高速下泄水流的空间拉伸、扩散消能，降低边墙的高度，保证结构的稳定，同时，该挑坎中部设置有嵌入基岩的扩散型跌坎，增加挑坎结构的稳定性，保证水舌起挑。
