Semi-fabricated ultra-deep laminated water storage tank and construction process

The invention relates to a semi-assembly type ultra-deep laminated water storage tank and a construction technology. The semi-assembly type ultra-deep laminated water storage tank comprises a prefabricated UHPC inner wall plate located on the innermost side, and an outer formwork is supported on the outermost side of the UHPC inner wall plate; the UHPC inner wall plates are connected through the anchor cables to form the UHPC inner wall plate assembly with the rectangular or circular cross section. The profile steel is evenly distributed on the periphery of the UHPC inner wall plate, and the profile steel and the UHPC inner wall plate are of an integrated or detachable structure. A steel reinforcement framework is bound between the outer side of the profile steel and the outer template; concrete is poured between the UHPC inner wall plate and the outer formwork to form an SRC outer wall plate; the tail end of the UHPC inner wall plate is poured in the reinforced concrete bottom plate, and a post-pouring groov
