Automated Lining System of Middle-Performance Concrete Using ICT:the Yuasa-Gobo Road, the Kawabe Dai-Ni Tunnel

摘要

Automated lining system for middle performance concrete is basically consisted of pouring fresh concrete that has superior fluidity and unseparated state in a sliding form using a device of switching pipe with manipulator and compacting it with form vibrators (VB). The realization of automated concrete lining is based on patterning concrete lining, using ICT, digitizing and visualizing with all kinds of sensors to evaluate status of working and compacting and automatically controlling pouring device with the manipulator and form vibrators (VB). In this report we show that it was possible to confirm the adaptability and effectivity of this automatic concrete lining through model construction and we were able to obtain basic data on parameters of lining such as concrete pressure while pouring and pausing, compacting energy, strength at the time of form removal and complete shape and degree of rebound.
