Gate dam fishtail pier structure
The invention belongs to the technical field of water conservancy and hydropower engineering, and particularly discloses a gate dam fishtail pier structure with high erosion resistance. According to the gate dam fishtail pier structure, the structure of a fishtail pier is divided into a fishtail pier middle-upper section, a fishtail pier foundation section and a fishtail pier bottom plate section from top to bottom, and the fishtail pier bottom plate section is poured into a pier groove in an energy dissipation facility bottom plate; meanwhile, an anchor bar bundle with the upper end and the lower end extending into the fishtail pier foundation section and the energy dissipation facility bottom plate correspondingly is buried in the fishtail pier bottom plate section; therefore, the strength of the fishtail pier structure can be enhanced, the possibility that a connecting part of the fishtail pier foundation section and the energy dissipation facility bottom plate becomes a weak part is reduced, and the erosion resistance of the fishtail pier is improved; and moreover, the integrality of the fishtail pier and the bottom plate of the energy dissipation facility is enhanced, the frequency and amplitude of reciprocating vibration of the fishtail pier caused by water flow pulsating pressure can be reduced, so that the possibility of local damage and even toppling of the fishtail pier is reduced, and the economic benefit and the safety guarantee of the facility are increased.
本发明属于水利水电工程技术领域，具体公开了一种抗冲蚀能力较强的闸坝鱼尾墩结构。该闸坝鱼尾墩结构通过将鱼尾墩的结构从上往下分区为鱼尾墩中上段、鱼尾墩基础段和鱼尾墩底板段，并将鱼尾墩底板段浇筑于消能设施底板上的墩槽中，同时在鱼尾墩底板段中埋设上下两端分别伸入鱼尾墩基础段和消能设施底板中的锚筋束；如此不仅可以加强鱼尾墩结构的强度，降低鱼尾墩基础段与消能设施底板衔接部位成为薄弱处的可能性，提高鱼尾墩的抗冲蚀能力；而且，加强了鱼尾墩与消能设施底板的整体性，可以降低水流脉动压力造成的鱼尾墩往复振动的频率和幅度，从而降低鱼尾墩局部损坏甚至倾倒的可能性，增加了设施的经济效益和安全保障。
