River bank slope protection structure and river bank slope protection method

The invention provides a river bank slope protection structure which comprises a lifting plate, a fixing plate, a first lifting hydraulic rod, a fixing communication seat, a horizontal hydraulic rod and a baffle, the fixing plate is fixedly arranged on a river bank slope, the lifting plate is slidably connected with the fixing plate, and the telescopic end of the first lifting hydraulic rod is fixedly connected with the lifting plate; the fixed end of the first lifting hydraulic rod communicates with the fixed end of the horizontal hydraulic rod through a fixed communicating base, so that hydraulic oil in the first lifting hydraulic rod and the horizontal hydraulic rod circulates, the fixed communicating base is arranged on the fixed plate through bolts, and the telescopic end of the horizontal hydraulic rod is fixedly connected with the baffle. The water level in the river channel rises, water flow impacts a baffle, the baffle applies pressure to the telescopic end of a horizontal hydraulic rod, hydraulic oi
