[0002] Curving mirrors are also called convex mirrors and wide-angle mirrors. They are mainly used in various highway projects at bends and intersections. They can expand the driver's field of vision and detect vehicles coming from the opposite side of the bend early to reduce the occurrence of traffic accidents.

[0003] During the construction of mountain highway projects, in order to ensure that vehicles can safely pass through the mountain curves, it is necessary to install bending mirrors at the curves. However, the slopes of mountain roads are different and the angles of curves are different. In order to ensure that the bending mirrors can be aligned with the road, it is usually necessary to adjust the height and angle of the bending mirrors. In order to facilitate the rapid installation of the bending mirrors on mountain roads and adjust the height and angle as needed, a bending mirror installation structure and an installation method for highway engineering are proposed. The whole structure can be divided into three parts, and the three parts can be connected and assembled in a factory and can be quickly connected after being transported to the installation location. Such a prefabricated split structure is easy to transport and manufacture, and such an installation structure is easy to adjust the angle and height of the mirror according to the slope and curvature of the road, so that the bending mirror can be suitable for the construction of tortuous mountain highway projects and has better applicability.
