Dam body flood discharge structure of concrete gravity dam with combination of narrow slit and tongue-shaped ridge and construction method
The invention relates to a dam body flood discharge structure of a concrete gravity dam combining a narrow slit with a tongue-shaped ridge and a construction method. The method is suitable for the technical field of water conservancy and hydropower engineering. The technical problem to be solved by the invention is to provide the dam body flood discharge structure of the concrete gravity dam combining the narrow slit with the tongue-shaped ridge and the construction method. According to the technical scheme, the dam body flood discharge structure with the narrow slit combined with the tongue-shaped ridge of the concrete gravity dam comprises an overflow dam section arranged on a dam body, and the overflow dam section is composed of two side piers, a plurality of middle piers and a plurality of overflow holes between the side piers and the middle piers and between the middle piers; upstream inlets of all the overflow holes are of practical weir structures, downstream outlets of the first part of overflow holes are narrow slits and flow out through a straight concrete bottom plate, the concrete bottom plate inclines downwards by a certain angle, downstream outlets of the second part of overflow holes are tongue-shaped ridges, and the tongue-shaped ridges are overhung on the downstream face of the dam; and the narrow slits and the tongue-shaped ridges are arranged at intervals.
本申请涉及一种混凝土重力坝窄缝结合舌形坎的坝身泄洪结构及施工方法。本申请适用于水利水电工程技术领域。本申请要解决的技术问题是：提供一种混凝土重力坝窄缝结合舌形坎的坝身泄洪结构及施工方法。本申请所采用的技术方案是：混凝土重力坝窄缝结合舌形坎的坝身泄洪结构，包括设置在坝身上的溢流坝段，该溢流坝段由两个边墩、若干个中墩以及边墩与中墩之间、中墩与中墩之间的若干个溢流孔组成；所有溢流孔的上游进口均采用实用堰结构，第一部分溢流孔的下游出口为窄缝且利用平直的混凝土底板出流，混凝土底板下倾一定角度，第二部分溢流孔的下游出口为舌形坎，舌形坎悬挑于大坝下游面；所述窄缝与舌形坎间隔排列。
