Pipeline integration ALC partition wall, prefabricated pipeline and wire box in the retaining wall, directly saving the construction technology of slotting, burying pipe, repairing and blocking. The construction of the same floor is the ALC wall panel in the main structure construction stage, in the downstairs pre-assembly into a whole wall panel, the development of new wall panel fixtures, lifting AIDS, such as lifting tools, with the realization of the integrated lifting process after pre-assembly. Combined with the actual construction schedule, this paper innovatively adopts the same floor construction method as the main body, analyzes the traditional construction scheme and the same floor construction scheme technology and construction period respectively, and then uses AHP method to calculate the influence degree of the factors influencing the construction period of the two schemes. The research results show that the ALC partition wall adopts the same floor construction scheme, which saves the construction time of the secondary structure, and has a natural advantage over the traditional scheme in terms of saving processes, which can effectively reduce the management pressure and reduce the influence of additional factors on the total construction period.
