Device for preventing earth and rockfill dam from being damaged by excessive overtopping flood and protection method
The invention discloses a device and a protection method for preventing an earth and rockfill dam from being damaged by excessive overtopping flood, the device comprises a rockfill dam body and dam slopes on the two sides, the dam slope on the front side is an upstream section, and the dam slope on the rear side is a downstream section, the device is characterized in that a first protection layer structure is arranged at the top of the rockfill dam body, and when the protection layer structure shrinks, the first protection layer structure is connected with the first protection layer structure; a wave wall can be formed; and the second protection layer structures are arranged on the two dam slopes correspondingly, the second protection layer structure is located on the upstream section dam slope, and the second protection layer structure is located on the downstream section dam slope. Through the structural arrangement of the second protective layer structure, the geomembrane can be folded and stored in a contraction state and can be prevented from being exposed to the sun, the strength and the supporting stability are greatly improved through the geomembrane supported by the supporting strips in a triangular mode in a tiled state, and the geomembrane can be used for preventing scouring of the overtopping top of the earth and rockfill dam and reducing damage to a dam slope in a downstream area.
本发明公开了一种防止土石坝超标漫顶洪水破坏的装置及保护方法，包括石坝本体以及两侧的坝坡，前侧的坝坡为上游区段，后侧的坝坡为下游区段，其特征在于，所述石坝本体顶部设置有第一保护层结构，当保护层结构收缩时，可用于形成挡浪墙；以及分别设置在两个所述坝坡上的第二保护层结构，位于上游区段坝坡所在的第二保护层结构，位于下游区段坝坡所在的第二保护层结构。本发明通过第二保护层结构的结构设置，在收缩状态下，可折叠收纳，避免风吹日晒，在平铺状态下，通过支撑条三角支撑的土工膜，在强度和支撑稳定性大大加强，可用于防止土石坝漫顶的冲刷，降低下游区域坝坡的破坏。
