Flood-discharging energy-dissipating structure capable of relieving water flow impact vibration influences of high gate dam sluice chamber
The invention discloses a flood-discharging energy-dissipating structure capable of relieving water flow impact vibration influences of a high gate dam sluice chamber. The flood-discharging energy-dissipating structure comprises a primary stilling basin, a secondary stilling basin and a tail ridge, which are sequentially arranged at the downstream of a water gate sluice chamber, wherein a nose ridge at the tail end outlet of the water gate sluice chamber adopts a flat-bottom nose ridge; the front part of the primary stilling basin is provided with a vertical drop; the tail part of the primarystilling basin is provided with a continuous type baffle ridge with a vertical upstream face; while the continuous type baffle ridge is positioned at downstream low water level for operating a controlworking condition, a position 1-2 m at the upstream of a critical point position with water jump is submerged in the primary stilling basin. The figure of the outlet structure is regulated for controlling and guiding discharged water flow, and over-drive type water jump away from the sluice chamber is formed while downstream low-water-level operation is controlled, and critical or slightly submerged water jump is formed for dissipating energy, so that structure safety and normal use function requirements are met; and meanwhile, the flood-discharging energy-dissipating structure has very goodeconomical efficiency, and has very demonstrative and referential significance for designs of other similar projects.
本发明公开了一种减缓高闸坝闸室水流拍击振动影响的泄洪消能结构，包括依次设置在水闸闸室下游的一级消力池、二级消力池和尾坎，水闸闸室末端出口鼻坎采用平底鼻坎，一级消力池池首设置竖直跌坎，一级消力池尾部设置迎水面直立的连续式消力坎，连续式消力坎位于下游低水位运行控制工况时，一级消力池内淹没水跃发生的临界点位置上游的1～2m。本发明通过调整出口结构体形，将下泄水流进行控制引导，首先控制在下游低水位运行时形成远离闸室的远驱式水跃，然后再形成临界或稍有淹没的水跃进行消能，既满足了结构安全、正常使用功能要求，同时具有较好的经济性，对其它类似工程的设计具有很好的示范性和借鉴意义。
