Perfusion；
3.: after the filling concrete of the setting position is full, set distance is integrally retreated by walking carriage (1), simultaneously
Slurries conveying mechanism (2) are driven to retreat, until filling whole plate concrete；And in filling process, is driven and filled by push-and-pull component
Gun barrel (5) push-and-pull move is starched, prevents grouting gun barrel (5) and concrete from combining；
4.: after the completion of grouting, the connection between grouting gun barrel (5) and slurries conveying mechanism (2) is removed, while releasing walking carriage
(1) connection between slurries conveying mechanism (2)；
5.: walking carriage (1) moves close to the concrete end face of perfusion, re-lays splash guard and assembling reinforcement operation；
6.: after the completion of laying, repeat step 1. to step 5..
