The invention relates to a high-performance composite wallboard, a manufacturing method thereof, and an installation method thereof. The invention belongs to the filed of civil engineering and building construction. The invention relates to a construction, manufacturing, and installation method of a construction retaining wallboard. The invention provides a high-performance, multi-functional, high-endurance retaining wallboard suitable for both reinforced concrete structure and steel structure constructions. The wallboard can be flexibly pre-cast and produced on sites, factories and workshops, mechanically assembled on site, conveniently operated with low cost, and rapidly constructed. During an application period, the wallboard is green, energy-saving, and healthy. According to the invention, a specially produced light steel net framework is adopted as a wall frame; a variety of structural layers (such as a light concrete layer) are sequentially composed according to a regulated process in a factory or a workshop, such that the composite wallboard is formed. The installation method of the wallboard comprises steps that: when the wallboard is pre-cast, only the light steel framework is reserved on the edges; the light steel framework is fixed by welding or fastening with reserved iron pieces on a surrounding structural beam or a column (wall); a detaching-free template is fixed on the exposed framework by using bolts (nails); and an integral wallboard is formed through polyurethane foaming.
