Abstract
This utility model discloses a roadbed protection structure for the demolition of existing walls, including an existing wing wall with its wing wall portion removed and an existing culvert section, as well as an extended culvert section; the extended culvert section is set at the original wing wall location; a borehole is drilled on the side of the existing wing wall near the extended culvert section; a protective component is inserted into the borehole. By arranging the protective component at the original wing wall location (which has been demolished) of the existing wing wall, and then carrying out the extension construction of the culvert and bridge; by embedding the protective component into the back of the existing wing wall to form a skeleton, a temporary embedded retaining wall can be formed with steel plates, which can effectively replace the retaining function of the reduced height portion of the wing wall after cutting it (wing wall).
