Abstract
The utility model relates to the technical field of culvert pipe prefabrication, in particular to a rectangular culvert pipe full-section prefabrication formwork. Comprising two side molds which are symmetrically arranged on the two side edges of the culvert pipe reinforcement cage; the core mold assembly is arranged in the culvert pipe reinforcement cage; a plurality of sets of parallel buttress assemblies are arranged in a bottom plate reinforcement cage, the buttress assemblies extend in the length direction of the core mold assembly, a guide rail is arranged above each buttress assembly, and the core mold assemblies slide along the guide rails so that the core mold assemblies can be pulled out of the poured culvert pipe reinforcement cage. According to the method, one-time pouring of the whole section of the rectangular culvert pipe can be achieved, layered prefabrication is not needed, concrete connection positions do not need to be treated, the appearance quality of the prefabricated culvert pipe is improved, the construction cost is saved, the construction efficiency is greatly improved, and the prefabrication construction period is shortened.
