High-speed rail ballastless track plate composite system based on natural circulation and construction method thereof
The invention belongs to the technical field of high-speed railways, and particularly discloses a high-speed railway ballastless track plate composite system based on natural circulation and a construction method of the high-speed railway ballastless track plate composite system. Small-size heat pipes are embedded in track plates, and on the premise that the physical and mechanical properties of the track plates are not affected, the high-speed railway ballastless track plate composite system is formed through the efficient heat conduction performance of the heat pipes; efficient transfer of the temperature in the track plate is achieved, passive temperature regulation and control are achieved through phase change heat transfer of the heat pipes, input of external energy is not needed, and the influence of external conditions can be avoided when the heat pipes are embedded in the track plate; the unbalanced thermal stress distribution condition of the track board can be effectively improved, the occurrence of thermal diseases such as cracks and upward arching gaps caused by temperature stress is reduced, and the driving safety of a high-speed railway is ensured.
本发明属于高速铁路技术领域，具体公开了基于自然循环的高铁无砟轨道板复合系统及其构建方法，通过在轨道板内部埋入小体积的热管，在不影响轨道板的物理力学性质的前提下，通过热管高效的热传导性能，实现轨道板内部温度的高效传递，热管通过相变传热实现被动温度调控，不仅无须外部能源的输入，且埋入在轨道板内部也能够避免外部条件的影响；能够有效的改善轨道板的热应力分布不平衡条件，减少因温度应力导致的裂缝、上拱离缝等热病害的发生，保证高速铁路的行车安全。
