Construction Example of the Hydration Heat Control for Foundation of Yang Pyeong Bridge with Pipe Cooling

파이프쿨링을 적용한 양평대교 직접기초의 수화열 제어대책에 관한 시공사례

The Yang Pyeong bridge is high the occurred possibility of temperature crack by means of hydration Heat when the foundation of is constructed. Therefore, a pipe-cooling method was applied for reducing the temperature crack. Using the measured temperature curve when construction was carried out, the measured value and different facts were analyzed. In this paper, cause and analysis with respect to a mentioned above is to discuss firstly, and thermal characteristics of concrete and construction method hereafter is also discussed.
