Assembled concrete protection slope component

The utility model relates to an assembled concrete protection slope component used as a container for receiving silt of water loss and soil erosion and planting plants. The component comprises Y-shaped frames 1 and a semi-nested container 2 and is characterized in that the semi-nested container component and the Y-shaped frame components are assembled into a unit structure body which is combined into the overall protection slope. The Y-shaped frame 1 is a substance component consisting of symmetrical legs 1a and a supporting leg 1c, and the bottom of 1c is provided with a ramp or a serrated groove which is correspondingly connected with a bulge face 2c of the semi-nested container. Three Y-shaped frames 1 and one semi-nested container 2 are assembled into a unit structure body. The utilitymodel is in conformity with ecological principles, can be suitable for protecting a variety of slopes needing slope protection; the protection slope component is applied for managing wind erosion areas, fixing and greening s
