The invention discloses a water conservancy dam structure with anti-seepage and anti-scouring-collapse functions. The water conservancy dam structure comprises a protecting outer frame, a bell-ringingalerter and a drainage pipe. Transverse reinforcing rods are mounted inside the protecting outer frame, and vertical reinforcing rods are fixed between the transverse reinforcing rods; a concrete layer is arranged at the internal lower end of the protecting outer frame; the bell-ringing alerter is mounted at the upper end of a vegetation cultivating layer; reinforcing waterproof plates are mounted on the outer side of the protecting outer frame, water level sensor protecting shells are mounted on the outer sides of the reinforcing waterproof plates, and water level sensors are mounted insidethe water level sensor protecting shells; and the drainage pipes are mounted at the outer end of a gravel layer. In the water conservancy dam structure with the anti-seepage and anti-scouring-collapsefunctions, by arranging a waterproof gauze layer, a waterproof layer and a corrosion-resistant layer, a water conservancy dam can have waterproof and corrosion-resistant functions, so that the service life of the water conservancy dam is prolonged advantageously; and by arranging the transverse reinforcing rods and the vertical reinforcing rods inside the protecting outer frame, the water conservancy dam has supporting stabilizing performance, so that the supporting performance of the water conservancy dam is extremely excellent.
