Novel template for tunnel portal external expansion type open cut tunnel protection structure
The invention discloses a novel template for a tunnel portal external expansion type open cut tunnel protection structure, which comprises a mold A, a mold B, a mold C, a mold D and a mold E. The mold E is assembled and installed outside the mold A, one end of the mold A and one end of the mold E are combined and spliced to form an external expansion type flared brim main body, the mold B is fixedly installed at one end of the mold A, the mold C is installed on one side of the mold B, and the mold D is installed on the other side of the mold B; the mold D is mounted on one side of the mold C and corresponds to the mold B, and the mold B, the mold C and the mold D form a protective bulge; through the designed horn-mouth-shaped external expansion type tunnel portal brim protection structure, falling rocks can be blocked through the brim protection structure, so that the phenomenon that the falling rocks and the like directly fall on a road is reduced, and through the horn-mouth external expansion type shape, generated airflow can be guided and discharged when a vehicle enters a tunnel portal; therefore, noise generated by gas explosion is reduced.
本发明公开了一种新型隧道口外扩型明洞防护结构用模板，包括A模、B模、C模、D模和E模，所述E模组装安装在A模的外部，且A模和E模的一端组合拼接为外扩型喇叭口状的帽檐主体，所述B模固定安装在A模的一端，所述C模安装在B模的一侧，所述D模安装在C模的一侧且与B模对应，且B模、C模、D模组成防护凸起；通过设计的喇叭口状的外扩型隧道口帽檐防护结构，可以通过帽檐防护结构对落石进行阻挡，从而减少落石等直接掉落到路上的现象，且通过喇叭口外扩型的形状，在车辆进入隧道口时可以对产生的气流起到导向外排的作用，从而减少气爆产生的噪音。
