Elevation-adjustable transition section structure and elevation adjusting method thereof
According to the high-speed railway roadbed transition section structure with the adjustable elevation, a jack is arranged below a butt strap, the butt strap is jacked to enable the elevation of the top face of a steel rail in the butt strap range to linearly change, and then a gap between the butt strap and a roadbed is grouted to eliminate void. On one hand, the stress condition of the butt strap is greatly improved, the driving safety is improved, and on the other hand, the linearly changed steel rail top surface elevation can also improve the line smoothness and improve the driving comfort.
一种高程可调整高速铁路路基过渡段结构，通过在搭板下设置千斤顶，顶升搭板使得搭板范围内钢轨顶面高程线性变化，然后对搭板和路基之间的空隙进行注浆以消除脱空。本发明一方面大大改善搭板的受力状况，提高行车安全性，另一方面线性变化的钢轨顶面高程也可改善线路平顺性，提高行车舒适性。
