[0023] Working principle: Traditional on-site pouring requires on-site splicing of molds and waiting for the poured concrete to completely solidify, which takes a long time. However, manufacturing cable wells of suitable specifications in advance reduces the waiting time required for on-site manufacturing, which greatly improves construction efficiency. Embedded parts are embedded in the prefabricated cable wells and grounded to the outside through the embedded parts, thereby ensuring that the inside of the prefabricated cable well is in a safe working environment.
