Railway tunnel bottom structure and floor heave treatment method
The invention relates to a railway tunnel bottom structure and a floor heave treatment method. The railway tunnel bottom structure comprises a unit track sleeper body, a unit transition supporting body, a unit supporting arch and a unit cover pressing sleeper body. The unit cover pressing sleeper body supports the ballastless track of the railway; the unit transition support body supports the unit rail sleeper body; the unit supporting arches are matched with the side walls in an abutting mode. The unit supporting arch moves and is linked with the unit supporting arch to vertically move through the transmission unit, and vertical abutting supporting on the side wall is carried out. The tunnel bottom structure has the beneficial effects that stress concentration generated by geological changes of the tunnel can be eliminated, then the problem of tunnel bottom heaving can be effectively eliminated, the tunnel bottom structure of the tunnel is in a movable state, impact inertia generated when a high-speed rail passes through the tunnel can be effectively transmitted to the position of the side wall so as to be vertically transmitted into the side wall, and the impact inertia is effectively prevented from being damaged. And absorption is carried out through a tunnel bottom structure of the tunnel, so that the problem of tunnel bottom heaving caused by impact inertia when the high-speed rail passes through can be effectively eliminated.
本发明涉及铁路隧道隧底结构及底鼓治理方法，包括：单元轨道枕体、单元过渡支撑体、单元支撑拱和单元盖压枕体；单元盖压枕体实施对铁路无砟轨道的支撑；单元过渡支撑体实施对单元轨道枕体的支撑；单元支撑拱与侧墙构成抵靠配合；单元支撑拱移动且通过传递单元连动单元支撑拱竖直移动且实施对侧墙的竖直抵靠支撑。本发明的有益效果是：本发明可以消除隧道地质变化而产生的应力集中，进而可有效消除隧道底鼓问题的产生，该隧道的隧底构造呈现活动的状态，当高铁通过该隧道时产生的冲击惯量，可有效传递至侧墙位置，以竖直传递至侧墙内，并且通过隧道的隧底构造进行吸收，从而可有效消除高铁通过的冲击惯量产生的隧道底鼓问题。
