[0016] The following is combined with Figure 1 -Attached Figure 4 The present invention is described in further detail.

[0017] The embodiment of the present invention discloses an elevator shaft, a sump prefabrication mold and a prefabrication method. Figure 1-Figure 3 The prefabricated mold for the elevator shaft and the sump includes a prefabricated template 1 and a supporting frame 2. After the concrete solidifies, a prefabricated part 3 is formed. During the steel bar binding stage, a lifting ring 4 is installed on the prefabricated part 3 so that the prefabricated part 3 and the prefabricated template 1 can be lifted into the foundation pit together through the lifting ring 4 later.

[0018] Reference Figure 1-Figure 3The prefabricated template 1 includes an outer template 10, an inner template 11, a lower bottom template 12 and an upper bottom template 13. The outer template 10 is assembled into a rectangular frame shape by four templates, and the templates can be fixed by anchors; the inner template 11 is located inside the outer template 10, and the inner template 11 is assembled into a rectangular frame shape by four templates, and the templates can be fixed by anchors, and the template height of the inner template 11 is less than the template height of the outer template 10; the lower bottom template 12 is located below the outer template 10 and is fixed to the outer template 10 by anchors; the upper bottom template 13 is located below the inner template 11 and is fixed to the inner template 11 by anchors.

[0019] Reference Figure 1-Figure 3 The support frame 2 is supported inside the inner mold 11. The support frame 2 is constructed by multiple steel pipes with fasteners. The support frame 2 is in the form of a full-floor scaffolding to prevent the inner mold 11 from deforming during concrete pouring and molding.
