Disclosed is a thin wall non-symmetrical double-hole hollow column structural construction method. The thin wall non-symmetrical double-hole hollow column structural construction method comprises the following steps that a scaffold is built, and a steel bar cage is strapped; hole interior wooden formworks are installed, wherein soft-texture PVC films are pasted on the inner surfaces of the hole interior wooden formworks; a rectangular space formed by the hole interior wooden formworks is filled with inflation interior moulds, outer mould formworks are installed, and concrete is cast; and in the casting process, air pressure of inflation cores in the inflation interior moulds is consistently increased, and the inflation interior moulds, the hole interior wooden formworks and the outer mould formworks are detached. By means of the thin wall non-symmetrical double-hole hollow column structural construction method, the casting process can be completed once, so the construction cost is low, and the speed is fast; in addition, the soft-texture PVC films are pasted on the inner surfaces of the hole interior wooden formworks, so the PVC films can fall down fast during formwork detaching, and dust staining is not achieved; and the inflation interior moulds can be combined arbitrarily according to the size of column interior holes, and the interior pressure can be adjusted according to construction situations, so it can be ensured that the hole interior wooden formworks are stable.
