[0003] However, although the prefabricated inspection well mold in the prior art has achieved easy disassembly and assembly, it still has some shortcomings: the existing prefabricated inspection well mold requires manual spraying of the release agent when pouring concrete, so as to facilitate the demolding of the inspection well molded parts after opening and closing. However, for larger inspection well molds, manual spraying of the release agent is more troublesome and poses certain hazards to the human body; secondly, when the existing inspection well mold is used to build concrete, due to the viscosity of the concrete and its slow flow, the concrete in the mold cavity between the inner mold and the outer mold cannot be quickly flattened, resulting in reduced molding efficiency.
