Anti-erosion parting structure of dam crest spillway of concrete faced rockfill dam and combined discharge chute of anti-erosion parting structure
The invention provides a panel dam crest spillway anti-erosion parting structure and a combined discharge chute thereof, and the parting structure is characterized in that a bottom plate assembly is arranged on a plain concrete cushion layer of the panel dam spillway discharge chute, and the bottom plate assembly is provided with a longitudinal joint; the anti-corrosion cover covers the longitudinal seam; the anti-corrosion cover is arranged on the bottom plate assembly through the mounting assembly; the water stop assembly is arranged in the bottom plate assembly. Through the arrangement of the anti-corrosion cover and the installation assembly, the anti-corrosion cover covers the longitudinal joint and adapts to slab staggering generated by uneven settlement between the bottom plates, high-speed water flow is isolated from the slab staggering of the bottom plate assembly through the smooth and flat anti-corrosion cover, and therefore it is guaranteed that the overflowing face at the longitudinal joint is flat and smooth; therefore, the gas corrosion of the staggered slab at the longitudinal joint of the bottom plate assembly under the action of high-speed water flow is effectively avoided, the safety of the discharge chute and the dam is ensured, the safety parting of the spillway discharge chute at the crest of the concrete faced rockfill dam becomes possible, and a support is provided for the application of the large-span discharge chute of the spillway at the crest of the concrete faced rockfill dam.
本申请提出一种面板坝坝顶溢洪道防冲蚀分缝结构及其组合式泄槽，该分缝结构包括：底板组件设置在面板坝溢洪道泄槽的素混凝土垫层上，底板组件上具有纵缝；防蚀罩覆盖在纵缝处；防蚀罩通过安装组件设置在底板组件上；止水组件设置在底板组件内。通过防蚀罩以及安装组件的设置，使防蚀罩对纵缝进行覆盖，并适应底板之间不均匀沉降而产生的错台，通过光滑和平整的防蚀罩将高速水流与底板组件的错台隔离开来，以保证纵缝处的过流面平整和光滑，从而有效避免底板组件纵缝处的错台在高速水流作用下发生气蚀，保障泄槽和大坝安全，使面板坝坝顶溢洪道泄槽的安全分缝成为可能，为面板坝坝顶溢洪道大跨度泄槽的应用提供支撑。
