Novel anti-rockfall system suitable for tunnel group portal in deep canyon zone
The invention relates to the technical field of mountain area tunnel portal rockfall prevention, and discloses a novel tunnel group portal rockfall prevention system suitable for deep canyon zones, and the novel tunnel group portal rockfall prevention system is horizontally installed between two mountains and located above bridges of two mountain area tunnel entrances. The buffer protection device comprises a main body structure and a buffer protection assembly installed above the main body structure. The main structure comprises a plurality of longitudinal steel pipes and a plurality of transverse steel pipes. Each longitudinal steel pipe is arched, and the two ends of each longitudinal steel pipe are fixed between two mountains through skewbacks; the transverse steel pipes are arranged between the longitudinal steel pipes, and the transverse steel pipes and the longitudinal steel pipes form an anti-rockfall system stress framework which is integrally arched and has a herringbone section; the buffer protection assembly comprises a composite buffer protection plate which is transversely arched and has an arc-shaped section, and the bottoms of the middle and the two sides of the composite buffer protection plate are connected with the longitudinal steel pipes of the main body structure through a plurality of spring buffers. The rockfall prevention system can obviously buffer rockfall impact force and has the advantages of being independent in stress, good in protection effect, easy to construct and the like.
本发明涉及山区隧道洞口防落石技术领域，公开了一种适用于深切峡谷地带的隧道群洞口新型防落石系统，该隧道群洞口新型防落石系统水平安装于两山体之间，且位于两山区隧道洞口的桥梁上方，其包括主体结构和安装于主体结构上方的缓冲防护组件；主体结构包括若干纵向钢管和若干横向钢管；每个纵向钢管均呈拱形，两端通过拱座固定于两山体之间；横向钢管布设于纵向钢管之间，横向钢管与纵向钢管构成整体呈拱形，截面呈人字形的防落石系统受力骨架；缓冲防护组件包括横向呈拱形，截面呈圆弧形的复合缓冲防护板，复合缓冲防护板中间及两侧的底部通过若干弹簧缓冲器与主体结构的纵向钢管连接。该防落石系统能够显著缓冲落石冲击力，具备独立受力、防护效果好、易施工等特点。
