The invention relates to a convenient support construction method for a cover arch frame self-bearing template, which comprises the following steps of: positioning and mounting a steel arch frame, namely splicing the steel arch frame, measuring and positioning, and welding a guide steel pipe; pouring a concrete foundation; a formwork and a water stop screw rod are welded; pouring concrete; and maintenance treatment. The steel arch frame of the cover arch is used as a supporting system for cover arch concrete construction, the bottom formwork, the steel arch frame, the cover arch concrete layer and the outer formwork are connected into a whole through the water stop screws, a stable supporting system is formed, the effect that one arch frame plays two roles is truly achieved, and compared with existing tunnel formwork supporting cover arch construction, the construction efficiency is greatly improved. The supporting system is used for construction, the construction condition range is widened ...
