The two ends of the grille plate 2 are hinged to the column 1 through hinges 8 and hinged shaft seats 6. When in use, the two ends of the grille plate 2 adopt a hinge structure to rotate and hinge with the column 1. When encountering a sloping terrain, one end of the grille plate 2 is lifted, and the other end is rotated on the column 1 through the hinge 8 and the hinged shaft seat 6. By adjusting the inclination angle between the grille plate 2 and the column 1, the inclination of the grille plate 2 can be adjusted according to different slope terrains. It has a wide range of uses, accelerates construction efficiency, and brings great convenience to construction personnel.
