Concrete dam body spillway with I-shaped flaring piers, method and application
The invention belongs to the technical field of concrete dam body spillways, and particularly relates to a concrete dam body spillway with I-shaped flaring piers, a method and application. The structure comprises gate piers arranged on the left side and the right side of a spillway of a concrete dam body, an overflow face between the gate piers on the left side and the right side and I-shaped flaring piers. The I-shaped flaring pier is of a three-dimensional structure defined by a top plane, a quarter regular cone, a side vertical plane, a downstream face and a lower plane. The quarter regular cone is located at the joint of the side vertical plane and the top plane; i-shaped flaring piers are symmetrically arranged at the tails of the left gate pier and the right gate pier, and a gap is formed between the lower plane of each I-shaped flaring pier and the overflow surface to form a bottom opening of the corresponding I-shaped flaring pier. The method is suitable for a surface hole spillway in a concrete dam, and the larger the engineering scale is, the larger the flow is, and the effect can be better achieved. The method is suitable for combined use of a concrete dam face and the stilling pool, the length of the stilling pool can be greatly reduced, the work amount and investment of a bottom plate of the stilling pool are reduced, and single-hole full-open operation can be achieved.
本发明属于混凝土坝身溢洪道技术领域，具体涉及一种带有I形宽尾墩的混凝土坝身溢洪道、方法及应用。本发明包括设置在混凝土坝身溢洪道左右两侧的闸墩，左右两侧闸墩之间的溢流面及I形宽尾墩；I形宽尾墩是由顶平面、四分之一正圆锥、侧垂直平面、下游面和下平面围成的立体结构；四分之一正圆锥位于侧垂直平面与顶平面的衔接处；左右闸墩的尾部对称设置有I形宽尾墩，I形宽尾墩的下平面与溢流面之间有间距，形成I形宽尾墩的底口。本发明适用于混凝土坝中的表孔溢洪道，工程规模越大、流量越大，越能发挥其作用。本发明适合混凝土坝面、消力池联合使用，既可使消力池长度大幅减小，并减少消力池底板的工程量及投资，其能单孔全开运行。
