Protection structure of high-speed overflowing surface and construction method thereof
The invention discloses a protection structure of a high-speed overflowing surface and a construction method thereof. The structure comprises granites on a protection surface layer, secondary concrete on a middle transition layer and primary concrete on a base layer, wherein primary structural concrete reinforcements are arranged on the top surface of the primary concrete; secondary concrete surface layer reinforcements are arranged on the top surface of the secondary concrete; the primary concrete and the secondary concrete are connected through U-shaped ribs; the secondary concrete and the granites are connected through elbow anchor ribs or straight anchor ribs; and multiple granites are arranged in sequence to form an array, and are filled with gap concrete to be fixedly connected. The structure is novel in design idea, safe, reliable and convenient to operate, and greatly improves the scour resistance and the wear resistance of spillways. The structure is suitable for medium-high dam spillway engineering under bad river bed geological conditions.
