철도선로유지 효율화를 위한 궤도주변시설 성능개선 연구

Owing to high speed railroad and continuous welded rail, rail management is important, yet heat waves and abnormal climate phenomenon aggravate railway operation. A temperature rise in the section closed by railway noise barrier incurs the difficulty in track maintenance. For safe of operation of railways during a scorching summer, it is needed to maintain the temperature of rails at a certain level. Sprinkling water and the regulation of operating speed are used to respond to a temperature rise of rails, yet sprinkling water incurs the degradation of the efficiency in operating railways owing to the degradation of adhesion coefficient. Thus, automatic temperature sensing devices were installed on the sound barriers installed around the tracks so actuators and automatic sliding sound boards in operation according to the temperate set in advance could maintain the rail temperature, reducing the temperature of tracks by ventilation owing to automatic opening of sound boards at set temperature in the event of excessive temperate rise, ensuring the safety of railways operation during summers, and improving the performance of sound boards facilitating the extension of the maintenance cycle for rails, the materials of tracks.
