The invention relates to a water retaining device for hydraulic engineering construction, which is applied to the field of hydraulic engineering and comprises a water retaining plate mounted at the front end of a dam body and an intelligent water retaining control box arranged on the shore. The application state of the buffer strip is intelligently sensed and adjusted, when the buffer strip is subjected to impact damage, a warning prompt can be given, emergency protection measures on the buffer strip are effectively promoted, the problem that the flood control effect is weakened due to subsequent direct damage of a water fender is solved, the safety of a downstream area is guaranteed, and the service life of the water fender is prolonged. And the angle of the water retaining surface of the buffer strip can be adjusted according to the water flow state, the water flow can be guided and blocked, the situation that the water flow impacts and crosses the water fender to permeate to the downstream area is avoided, the flood prevention effect of the water fender is further improved, and the intelligence and safety of application of the water fender are promoted.
