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 erosi
