Safety anti-rockfall protection system for tunnel portal
The invention relates to the technical field of shed tunnels, and provides a tunnel portal safety anti-rockfall protection system which comprises an inner layer protection structure and a base connected with the two ends of the inner layer protection structure, the inner layer protection structure comprises corrugated plates and connecting flanges connected to the ends of the corrugated plates, and the connecting flanges on every two adjacent corrugated plates are attached and locked. The protection system further comprises an outer layer protection structure, the outer layer protection structure comprises a set of supports erected on the outer side of the corrugated plate and arranged in the longitudinal direction and a protection net erected between every two adjacent supports, and the two ends of each support are connected with the bases at the corresponding ends respectively. The problems that in the prior art, a steel protective net frame is mainly composed of a supporting frame and a protective net, small-size rockfall is not blocked, and driving safety is affected are solved.
本发明涉及棚洞技术领域，提出了一种隧道口安全防落石防护系统，包括内层防护结构、以及与内层防护结构两端连接的基座，内层防护结构包括波纹板、以及连接在波纹板端部的连接法兰，相邻两个波纹板上的连接法兰贴合并锁紧，防护系统还包括外层防护结构，外层防护结构包括架设在波纹板外侧且沿纵向排列的一组支架、以及架设在相邻两个支架之间的防护网，支架的两端分别与对应端的基座连接。解决了相关技术中钢铁防护网架主要由支撑架与防护网构成，缺少对小尺寸落石的阻挡措施，影响行车安全的问题。
