[0002] The mold structure for the fabrication of prefabricated components must meet certain strength and stability requirements, while also requiring high precision adjustment, and be easy to operate and pour concrete.

[0003] In the existing technology, semi-circular annular precast cylindrical segments require more reliable structural measures due to their asymmetrical distribution of the center of gravity compared to standard, regular, and symmetrical precast components. When the size of the precast cylindrical segments is relatively large, an operation platform that facilitates concrete pouring is also required. Existing molds for pouring symmetrical precast cylindrical segments are difficult to meet the requirements for convenient pouring of semi-circular annular precast cylindrical segments.
