High-speed rail tunnel portal protection structure and device for preventing debris flow disasters
The invention provides a high-speed rail tunnel portal protection structure and device for preventing debris flow disasters, which can effectively reduce the harm of debris flow in debris flow disaster frequently occurring areas to high-speed rail tunnel entrances and exits, and adopts the technical scheme that the high-speed rail tunnel portal protection structure comprises tunnel portal extension sections fixedly connected with the end face positions of the tunnel entrances and exits respectively; the section shape of each tunnel entrance and exit extension section is consistent with the shape of the tunnel portal, the tunnel entrance and exit extension sections extend in the direction away from the tunnel portal, the upper end face of each tunnel entrance and exit extension section is provided with a buffer structure, and the face, away from the corresponding tunnel portal, of each tunnel entrance and exit extension section is fixedly connected with a blocking body structure. According to the high-speed rail tunnel entrance and exit early warning device, early warning can be conducted on debris flow disasters, blocking and burying of the debris flow to the high-speed rail tunnel entrance and exit can be prevented, and combination of prevention and protection is achieved.
本发明提供的一种预防泥石流灾害的高铁隧洞口防护结构及装置，可以有效减少泥石流灾害多发区泥石流对高铁隧洞出入口的危害，其解决的技术方案是，包括分别与隧洞出入口端面位置固定连接的隧洞出入口延伸段，各个隧洞出入口延伸段截面形状与隧洞口形状一致且隧洞出入口延伸段向远离隧洞口方向延伸，各个隧洞出入口延伸段上端面均设有缓冲结构，各个隧洞出入口延伸段远离相应隧洞口的一面均固定连接有挡体结构，各个隧洞出入口延伸段均纵向对称固定连接有导流结构，各个导流结构输出端均设有固定连接在地面上的泥石流排导槽，本发明可以对泥石流灾害进行预警并防止泥石流对高铁隧洞出入口的阻断和掩埋，实现了预防和保护的结合。
