Cable bridge shield is a walking shield cable bridge line engineering for the power or communication cable, is pressed by steel plates, the top surface of the cable bridge shield (1) and the top surface on both sides of the flap (2) is concave convex shape, the top surface (1) on the convex surface (11) and concave (12) and continuous set, each convex concave (11) and (12) the two units in the same direction bent hem (2), (11) convex and concave (12) between the height of less than 8 mm, the utility model has the advantages of high strength structure of cable bridge shield, due to structural modeling the whole surface of the cover of the concave convex shape, thereby increasing the shield steel steel, because the strength of the steel increases, can be made of thinner material, such as the use of the same thickness of the strength of more than two times more than the original, its main advantage is to reduce a This product is not easy to deformation.
