For this reason, this example provides a kind of method for prefabricating realizing shield duct piece streamlined, automation, improves the production efficiency of shield duct piece and reduce production cost with this.
Method for prefabricating is implemented based on intelligent flow production line, this production line adopts four-wire system, namely line and 3 curing lines are built for 1, wherein build line and 3 curing lines are set up in parallel for 1, and production-line arrangement 13 moulds, curing line arranges 16 moulds, and can hold 5,7,10 cover segment dies respectively and run on streamline, early stage only considers that use 5 mold carries out Production line.
On this basis, this intelligent flow production line is also provided with PLC automatic control system, mold advancement system, framework of steel reinforcement transportation system, concrete feeding system, concrete casting injection system, traversing ferry-boat system, intelligent steam-cured control system.
Wherein, mold advancement system is separately positioned on pouring product line and maintaining production line, and the segment die promoted on pouring product line and maintaining production line moves respectively;
Traversing ferry-boat system matches with pouring product line and maintaining production line, mould is transported to maintaining production line from pouring product line or is transported to pouring product line from maintaining production line;
Concrete feeding system matches with concrete casting injection system, by concrete conveyance to concrete casting injection system;
