Flood bank for water conservancy project
The invention belongs to the technical field of flood control dams, and discloses a water conservancy project flood control dam which comprises a bottom plate, a dam body is arranged at the position, close to the downstream, of the top of the bottom plate, two limiting guardrails located on the front side and the rear side of the dam body are arranged at the top of the bottom plate, and positioning strips are arranged on the opposite faces of the two limiting guardrails. And the positioning strips are inserted into the two banks of the riverbed. When the buffer dam slides, the buffer dam needs to continuously overcome resistance such as friction to gradually approach the bottom plate, so that the impact strength of flood waves can be reduced, the direct impact strength on the dam main body is reduced, and when the damping dam is turned over and the sliding block is lifted, the moving resistance on the buffer dam can be further increased, and the service life of the buffer dam is prolonged. And meanwhile, due to lifting of the lifting sliding blocks, floating foreign matter which is lifted by waves and rushes over the buffer dam can be borne and pushed, so that the floating foreign matter slides to the top of the dam body under the action of the inclined faces of the lifting sliding blocks, and recovery is facilitated.
本发明属于防洪堤坝技术领域，且公开了一种水利工程用防洪堤，包括底板，所述底板的顶部靠近下游设置有堤坝主体，所述底板的顶部设置有位于堤坝主体前后两侧的两个限制护栏，两个所述限制护栏相背面设置有定位条，所述定位条插接于河床两岸内。本发明由于缓冲坝滑移时需要不断地克服摩擦等阻力以逐步向底板靠近，因此能够减缓洪水波浪的冲击强度，以减缓对堤坝主体的直接冲击强度，而翻转阻尼坝和提升滑块时，能够进一步增加对缓冲坝移动的阻力，从而进一步提高减缓冲击强度的效果，同时由于提升滑块的提升可以将波浪抬升并冲过缓冲坝的漂浮异物进行承接及推移，使其在提升滑块的斜面作用下滑落至堤坝主体的顶部，以便于回收。
