Side slope water and soil loss prevention structure and method for urban road construction

The invention discloses a side slope water and soil loss prevention structure and method for urban road construction. The side slope water and soil loss prevention structure comprises a side slope foundation soil layer, a vegetation layer, a side slope supporting frame, a supporting mechanism and a planting groove. Pile bodies are inserted into the side slope foundation soil layer by hammering an annular hammering piece, so that the bottom of a limiting ring is attached to the top of the side slope supporting frame, the position of the side slope supporting frame is limited, the road side slope is supported by the side slope supporting frame, then a rotating handle is rotated, a threaded rod is driven to rotate through rotation of the rotating handle, square sliding blocks are driven to move downwards through threaded fit between the square sliding blocks and rotation of the threaded rod, the square sliding blocks drive hinge rods to rotate along the hinge points of the hinge rods and connecting blocks, then
