| titleOfInvention | Water-pillow pool method used for overflow cofferdam energy dissipation platform |
| abstract | The invention relates to a water-pillow pool method used for an overflow cofferdam energy dissipation platform, belonging to the field of hydraulic engineering. The method comprises arranging a water-pillow pool at the overflow cofferdam energy dissipation platform through the following steps of: firstly, calculating the before-jump froudenumber of the hydraulic jump near the overflow cofferdam energy dissipation platform; confirming the total length of the energy dissipation platform according to the before-jump depth and the froudenumber of the hydraulic jump; calculating the length of the water-pillow pool according to defined length coefficient of the water-pillow pool in an inversion mode; and confirming the ratio of the depth of the water-pillow pool to the length of the water-pillow pool so as to obtain the depth of the water-pillow pool in combination with the slope of the front dam surface of the platform and the flow velocity direction of the water. By arranging the water-pillow pool at the overflow cofferdam energy dissipation platform, the wall jet energy of the dam surface can be absorbed, so that the flexible steering of the water is realized, and the bottom flow velocity is reduced; the soft landing of the water in the water-pillow pool is realized, the impact and fluctuation pressure to a bottom plate of the energy dissipation platform are reduced, and the energy dissipation effect is improved; and the washing of the water to protection surfaces and dam foundations at the downstream is reduced, so that the safe flood overflow of the overflow cofferdam is realized. |
