Y-shaped side groove spillway structure
The invention discloses a Y-shaped side groove spillway structure, and belongs to the technical field of water conservancy and hydropower engineering. The structure comprises a left wing side groove section, a right wing side groove section, a confluence section and a drainage section, the upstream end of the drainage section is connected with the downstream end of the left wing side groove section and the downstream end of the right wing side groove section through the confluence section, the joint of the left wing side groove section and the right wing side groove section is in smooth transition through an arc, and a plurality of sets of energy dissipation steps are arranged at the bottom of the drainage section. And the top of the energy dissipation step is detachably connected with a precast slab. The prefabricated plate is installed on the top of the energy dissipation step and is a cast stone plate, the cast stone plate can greatly improve the surface strength of the energy dissipation step, and when high-speed water flow scours the prefabricated plate, cavitation and cavitation erosion can be reduced, so that the service life of the energy dissipation step is prolonged, and the maintenance cost of the spillway is reduced. The prefabricated plates are connected with the top of the energy dissipation step through bolts, so that the prefabricated plates are convenient to install, and workers can maintain the energy dissipation step conveniently.
本发明公开了一种Y型侧槽溢洪道结构，属于水利水电工程技术领域。该结构包括左翼侧槽段、右翼侧槽段、汇流段和泄流段，所述泄流段的上游端通过汇流段与左翼侧槽段和右翼侧槽段的下游端连接，且左翼侧槽段和右翼侧槽段的连接处通过圆弧平滑过渡，所述泄流段的底部设有若干组消能台阶，且消能台阶的顶部可拆卸连接有预制板。消能台阶的顶部安装有预制板，预制板为铸石板，铸石板可以大幅度提高消能台阶的表面强度，当高速水流冲刷预制板时，会减少空化空蚀现象的产生，从而延长消能台阶的使用寿命，降低溢洪道的维护成本。预制板通过螺栓与消能台阶的顶部连接，使预制板安装较为便捷，方便工作人员维护消能台阶。
