Finally, the first inner mould assembly 3 is returned to the transverse state again through the hoisting equipment 4, and the inspection well is hoisted out of the first inner mould assembly 3 transversely. During lifting, because the upper template 32 moves towards the lower template 31, a gap exists between the bottom of the inspection well and the bottom of the lower template 31, so that the inspection well can be directly lifted transversely during lifting (the inspection well is lifted conveniently when the gap exists).
When the next inspection well is produced, the mould is required to be vertically arranged, at the moment, the lifting plate 5 can be lifted through the lifting belt 41 of the lifting device 4, the outer mould plate 2 and the inner mould assembly I3 are rotated to the vertical state, and then the reinforced bar frame and the poured concrete can be put in. When the mold is required to be removed, the outer mold plate 2 and the inner mold assembly I3 are transversely arranged by hoisting the hoisting plate 5.

In this embodiment, by moving the upper mold plate 32 and the inspection well downwards once and moving the inner mold assembly 3 downwards once, not only the cohesive force between the inspection well and the outer surfaces of the lower mold plate 31, the upper mold plate 32 and the separating block 33 is eliminated, but also the cohesive force between the outer mold plate 2 and the end of the inspection well is eliminated, and during lifting, on one hand, the inner mold assembly 3 can move downwards to eliminate the cohesive force, and the purpose of lifting the inspection well can be achieved.
The manner of eliminating the cohesive force in this embodiment is applicable to the round manhole 100 and the square manhole 200, and only the outer mold plate 2 and the inner mold assembly 3 need to be arranged in corresponding shapes.
