Reinforcing structure and method for water conservancy and hydropower dam

The invention relates to the technical field of dam reinforcing, in particular to a reinforcing structure and method for a water conservancy and hydropower dam. The device comprises a positioning device and a reinforcing device arranged on one side of the positioning device, the reinforcing device comprises a blocking mechanism, the blocking mechanism comprises a baffle, and a positioning mechanism is arranged on one side of the baffle. When the baffle is subjected to impact force from water flow, the baffle drives the tension frame to slide through the rotating rod and the positioning rod and then drives the baffle to rotate through the synchronizing mechanism, and due to the fact that the hinge position of the hinge rod and the baffle is fixed, when the hinge rod drives the baffle to rotate, the baffle is firstly driven to move downwards by a certain distance; the bottom end of the baffle is inserted into the deeper position in the sediment, at the moment, the included angle between the baffle and the horiz
