Slope protection supporting structure for water conservancy project

The utility model relates to the technical field of hydraulic engineering devices, in particular to a slope protection supporting structure for hydraulic engineering, which comprises slope protection plates, a splice plate, a stabilizing mechanism and a limiting mechanism, and the slope protection plates are mounted on two side surfaces of the splice plate. By arranging the inserting rods and the connecting pieces, the device can be stabilized when being installed on a river channel, meanwhile, when multiple devices are installed, the situation that a single slope protection plate is impacted by water flow excessively can be avoided, the water flow impact can be shared, splicing of the device is facilitated, and the stability of the device is improved; the impact force of water flow can be reduced through the arranged flow guide plates and buffer springs, and the water flow is guided, so that the situation that a soil layer falls off or soil is washed away along with the water flow when the slope protection i
