An Experimental Study on the Configuration Management for the Construction of Tapered Concrete Pylon of Super Long Span Bridge Using K-Slip Form System

The Korea Institute of Construction Technology (KICT) developed the K-slip form system by improving radically the previous slip form system for the erection of the tapered concrete pylon of super long span bridge. This innovative K-slip form system adopts the latest tapered slip form design technology using BIM, lightweight GFRP module favoring the early strength development of concrete owing to its outstanding insulation, electromotive spindle for the sectional adjustment, estimation system of concrete strength using ultrasonic wave, remote control system of the hydraulic jacks for the raising of slip form, and GPS-based configuration management system. A 10 m-high concrete pylon was erected successfully within 5 days using the K-slip form system as a mockup test. This paper focuses on the KICT Integrated Configuration Control System (KICS) developed for the configuration management of the tapered concrete pylon during its erection. The performance and applicability of KICS are validated through comparison of the measurement results provided simultaneously by the GPS-based KICS and the monitoring system traditionally adopted on site.
