Steel rail embedded type floating track bed
The invention relates to a steel rail embedded type floating track bed which comprises a plurality of sets of track units, each set of track unit comprises two sets of steel rails, a track bed body, two sets of track grooves, a plurality of sets of filling materials, a plurality of sets of air bags, a plurality of sets of under-track base plates and a plurality of sets of vibration isolation elements, and the two sets of track grooves are symmetrically formed in the top of the track bed body; the two sets of steel rails are installed in the two sets of rail grooves respectively, and the multiple sets of vibration isolation elements are arranged in gaps between a ballast bed and a bridge and tunnel foundation below the ballast bed. According to the embedded track, the steel rail can be adjusted after the filling material is in place, the situation that the steel rail in the adjusted state is interfered when the filling material is filled is avoided, the steel rail can be adjusted at any time, convenience and rapidness are achieved, and the problem that a traditional embedded track is difficult to adjust after the filling material is solidified and formed is solved; the vertical adjustment of the steel rail can be performed through the height of the floating track bed vibration isolation element, and the transverse adjustment of the steel rail can be realized by changing the air pressure in the air bag.
本发明涉及一种钢轨埋入式浮置道床，包括多组轨道单元，每组所述轨道单元均包括两组钢轨、道床、两组轨槽、若干组填充材料、若干组气囊、若干组轨下垫板以及若干组隔振元件，两组所述轨槽对称的形成在道床顶部，两组所述钢轨分别安装于两组轨槽内，若干组所述隔振元件设置于道床与下方桥、隧基础之间的空隙中。本发明中，钢轨调整可在填充材料到位后进行，避免填充材料时对已经调整好状态的钢轨进行干扰，钢轨调整可以随时进行，方便快捷，解决了传统嵌入式轨道在填充材料固化成型后难以调整的问题，并且钢轨的竖向调整可通过浮置道床隔振元件的高度进行，钢轨横向调整可以通过改变气囊内的空气压强实现。
