Earth and rockfill dam structure for preventing overtopping harm and construction method
The invention relates to an earth and rockfill dam structure for preventing overtopping hazards and a construction method. The earth and rockfill dam structure for preventing overtopping hazards comprises a dam, a self-chamber type wave wall, a dam crest drainage ditch and an intercepting ditch. Wherein the two sides, in the length direction, of the dam are combined with mountain bedrock; the self-chamber type wave wall is arranged at the dam top of the dam, the self-chamber type wave wall is located on at least one side, close to the mountain bedrock position, of the dam, the self-chamber type wave wall comprises a self-chamber gap and a self-chamber door, the self-chamber gap is used for forming a drainage gap for the self-chamber, and the self-chamber door is arranged at the position of the self-chamber gap in a blocking mode; the dam crest drainage ditch is arranged on the downstream side of the self-chamber type wave wall and communicates with the self-chamber notch. The intercepting ditch is arranged on the downstream side of the dam and communicates with the dam crest drainage ditch. The earth and rockfill dam structure capable of preventing overtopping hazards is simple in structure and low in cost, and meanwhile the overtopping risks of the earth and rockfill dam coping with excessive flood and the like can be effectively improved.
本申请涉及一种预防漫顶危害的土石坝结构及施工方法，该预防漫顶危害的土石坝结构包括大坝、自匮式防浪墙、坝顶排水沟和截水沟；其中，大坝沿长度方向的两侧与山体基岩结合；自匮式防浪墙设置于大坝的坝顶部位，且自匮式防浪墙位于大坝靠近山体基岩位置的至少一侧，自匮式防浪墙包括自匮缺口和自匮门，自匮缺口用于自匮形成排水缺口，自匮门封堵设置于自匮缺口的位置；坝顶排水沟设置于自匮式防浪墙的下游侧，坝顶排水沟与自匮缺口连通；截水沟设置于大坝的下游侧，截水沟与坝顶排水沟连通。该预防漫顶危害的土石坝结构在结构简易、费用低廉的同时，还能够有效提高土石坝应对超标洪水等存在的漫顶风险。
