Front trapezoid tooth groove drop sill stilling pool
The invention provides a front trapezoid tooth groove drop sill stilling pool which comprises a steep slope spillway, a drop sill stilling pool body and a trapezoid tooth groove drop sill arranged in front of the drop sill stilling pool body, the trapezoid tooth groove drop sill comprises at least two trapezoid flip buckets and drop sills, and the trapezoid flip buckets and the drop sills are arranged alternately; guide walls are arranged on the left side and the right side of the abrupt slope spillway and the left side and the right side of the drop sill stilling pool, vent holes are formed in drop sills of the trapezoidal tooth groove drop sills, the vent holes are communicated with vent wells on the outer sides of the left guide wall and the right guide wall, and a small flip bucket is arranged on a bottom plate of the abrupt slope spillway in front of the trapezoidal tooth groove drop sills. The front trapezoid tooth groove drop sill is arranged on the abrupt slope spillway or the overflow dam face in front of the stilling pool, the front trapezoid tooth groove drop sill has the function of decomposing discharged high-speed water flow into multi-strand drop flow and multi-strand flip flow, the water flow pulsating pressure of a bottom plate of the drop sill stilling pool can be reduced, the maximum near-bottom flow speed of the stilling pool is further reduced, and therefore the water flow pulsating pressure of the bottom plate of the stilling pool is reduced. The hydrodynamic characteristics of the stilling pool bottom plate are improved, the engineering design difficulty is reduced, and the engineering cost is saved.
本发明提供一种前置式梯形齿槽跌坎消力池，包括陡坡溢洪道、跌坎消力池以及设置于跌坎消力池之前的梯形齿槽跌坎，梯形齿槽跌坎包括至少两个梯形挑坎以及与梯形挑坎相间布置的跌槽；陡坡溢洪道和所述跌坎消力池的左右两侧设置有导墙，梯形齿槽跌坎的跌槽内设置有通气孔，通气孔与所述左右导墙外侧的通气井连通，梯形齿槽跌坎之前的所述陡坡溢洪道底板上设置有小挑坎。本发明于消力池前的陡坡溢洪道或溢流坝面上布置一道前置式梯形齿槽跌坎，其具有将下泄的高速水流分解为多股跌流和多股挑流的功能，可以减小跌坎消力池底板的水流脉动压力，并进一步降低消力池的最大临底流速，改善消力池底板的水动力特性，降低工程设计难度，节约工程成本。
