Slope protection precast block
The invention belongs to the technical field of hydraulic engineering slope protection, and particularly relates to a slope protection precast block which comprises a block body, an empty bag is arranged in the block body, a plurality of water inlet channels communicating with the empty bag are formed in the top face of the block body, a water outlet communicating with the empty bag is formed in the downstream end face, and a water inlet communicating with the empty bag is formed in the upstream end face. Each water inlet channel at least comprises two associated inclined vertical channels, lower openings of the two associated vertical channels are close to each other or communicated with each other, upper openings of the two associated vertical channels are far away from each other, and water flows out of the two associated vertical channels to perform hedging energy dissipation; a flip bucket is arranged on the top surface of the downward flowing end of the block body; an inserting block protruding outwards is arranged on the end face of the downward flowing end of the block body, and the water outlet is formed in the inserting block; an inserting groove matched with the inserting block is formed in the end face of the upstream end of the block body, and the water inlet is formed in the inserting groove; the precast block has the advantages that rainwater and dam overtopping water flow overflow the precast block, part of the water flow forms step-by-step falling flow, the water flow speed and kinetic energy are reduced, and scouring of the water flow to the slope protection is relieved; part of water flow is guided into the empty bag through the dam face water inlet channel, energy dissipation is conducted in the empty bag in multiple modes, then the water flow is guided to the downstream of the dam from the middles of the precast blocks, scouring of the water flow to the precast blocks is reduced, and therefore the safety of the dam is guaranteed.
本发明属于水利工程护坡技术领域，具体涉及一种护坡预制块，包括块本体，所述块本体的内部设有空囊，顶面设有与空囊连通的若干处进水通道，下游端端面设有与空囊连通的出水口，上游端端面设有与空囊连通的进水口；每处所述进水通道均至少包括两个关联的斜向的竖向通道，两个关联的竖向通道的下部开口相互接近或相互连通，两个关联的竖向通道的上部开口相互远离，水从两个关联的竖向通道流出后对冲消能；所述块本体的下流端顶面处设有挑流鼻坎；所述块本体的下流端端面处设有向外凸出的插块，所述出水口设置在插块中；所述块本体的上流端端面处设有可与插块配合的插槽，所述进水口设置在插槽中；优势在于：雨水、漫坝水流漫过本预制块，一部分水流形成逐级跌流，降低水流流速及动能，减轻水流对护坡的冲刷；一部分水流通过坝面进水通道引流进入空囊中，在空囊中通过多种方式消能后从预制块中间引流到到大坝下游，减少水流对预制块的冲刷，从而保证大坝的安全。
