The invention relates to a construction method for a fabricated enclosing wall. The construction method comprises the following steps that S1, materials are conveyed, specifically, prefabricated columns and prefabricated wallboards are conveyed to a construction site; S2, an enclosing wall foundation is manufactured, specifically, steel bar formworks are mounted and concrete is poured on the construction site, and thus the enclosing wall foundation is completed; S3, the prefabricated columns are mounted, specifically, before mounting, column position cross lines are snapped according to the size of a drawing, preformed holes are treated, the bottoms of the preformed holes are leveled through fine aggregate concrete according to the set mounting height, the prefabricated columns are mounted, and the positions of the prefabricated columns are adjusted; S4, the prefabricated wallboards are mounted, specifically, before mounting, the surface of the enclosing wall foundation is leveled, and the prefabricated wallboards are hoisted and fixed; S5, enclosing wall copings are mounted, specifically, the prefabricated wallboard coping and the prefabricated column coping are mounted respectively; and S6, seams are treated, specifically, seams between the prefabricated wallboards and corresponding prefabricated column grooves are filled. Compared with the prior art, the construction method for the fabricated enclosing wall has the advantages that material waste is avoided, manpower is saved, the time is saved, the cost is controllable.
