Method for top lift installation of inner tank and outer tank of double-wall storage tank

A method for top lift installation of an inner tank and an outer tank of a double-wall storage tank is used for solving the producing and installing problems of double-wall storage tank equipment. The method comprises the following construction steps: a, foundation acceptance treatment; b, outer tank bottom plate installation; c, tank bottom thermal insulating layer construction; d, inner tank bottom plate installation; e, inner tank top laying; f, inner tank first belt wall plate installation; g, outer tank top framework installation; h, inner tank top lift installation; I, other inner tank wall plate installation; j, inner tank accessory installation; k, outer tank wall plate installation; l, outer tank top plate layering; and m, test and thermal insulation construction. The method utilizes an inner tank and outer tank inverse assembling technology to simplify double-wall tank installation processes, aerial work quantity can be obviously reduced, the working efficiency is increased, the construction period is shortened, the safety of operating personnel is ensured, and the humanized construction idea is realized.
