Combined discharge chute for spillway at crest of concrete faced rockfill dam and construction method of combined discharge chute
The invention provides a combined discharge chute for a spillway at the crest of a concrete-faced rockfill dam and a construction method of the combined discharge chute. The discharge chute is characterized in that a plain concrete cushion layer is laid at a reserved position of the discharge chute of the concrete-faced rockfill dam; the bottom plate assembly is arranged on the plain concrete cushion layer, a longitudinal seam and a preformed hole are formed in the bottom plate assembly, the longitudinal seam extends in the thickness direction of the bottom plate assembly, and the preformed hole is perpendicular to the water flow direction or forms an acute angle with the water flow direction; the anchoring assembly penetrates through a reserved hole in the bottom plate assembly so that the bottom plate assembly can be locked. The waterproof assembly is arranged at the longitudinal seam. The discharge chute is arranged to be in a form of splicing the bottom plate assemblies, the longitudinal seams are formed in the bottom plate assemblies, the longitudinal seams are parallel to the water flow direction or form a certain angle with the water flow direction, and the bottom plate assemblies are locked together through the anchoring assemblies, so that the bottom plate assemblies are effectively prevented from excessively sliding or overturning under the action of water pressure; the stability of the bottom plate assembly is improved, water stop damage is avoided, and therefore the dam break accident caused by dam body scouring due to leakage of drained water is prevented.
本申请提出一种面板坝坝顶溢洪道组合式泄槽及其施工方法，该泄槽包括：素混凝土垫层铺设在面板坝泄槽的预留位置；底板组件设置在素混凝土垫层上，底板组件上具有纵缝和预留孔，纵缝沿底板组件的厚度方向延展，预留孔与水流方向垂直或与水流方向呈锐角设置；锚固组件贯穿底板组件上的预留孔，以使底板组件锁定；防水组件设置在纵缝处。通过将泄槽设置为底板组件拼接的形式，且在底板组件上设置纵缝，纵缝与水流方向平行或与水流方向形成一定角度，并通过锚固组件将底板组件锁定在一起，有效限制底板组件在水压力作用下发生过多滑移或倾覆，以提高底板组件的稳定性，避免止水破损，从而防止泄水外泄冲刷坝体而造成溃坝事故。
