Flexible shielding structure suitable for road engineering collapsed rockfall and construction method thereof
The invention relates to the technical field of collapsed rockfall shielding protection, and discloses a flexible shielding structure suitable for road engineering collapsed rockfall and a construction method thereof.The flexible shielding structure comprises a supporting structure arranged on the opposite side of a slope face of a steep mountain, the supporting structure is composed of a plurality of cantilever type supporting piles arranged in an array mode, and a connecting beam is arranged at the top end of the supporting structure. Waist beams are arranged at proper positions of the slope surface of the steep mountain and anchored on the slope surface of the mountain through reverse pre-stressed anchor cables. A flexible shielding protective net is connected between the supporting structure and the waist beam, and the net face is arranged over the building structure impacted by collapsed rocks and tends to the outer side of the building structure. The flexible shielding protective net is formed by weaving negative Poisson's ratio anchor cable materials and comprises a plurality of transverse steel strands and longitudinal steel strands, and the crossed positions are fixed through high-strength cross-shaped buckles. By the adoption of the flexible shielding structure and the construction method thereof, the protection energy level of a traditional high-position collapsed rockfall anti-impact flexible blocking net is broken through, and the flexible shielding structure has the functions of being high in toughness after being impacted by collapsed rockfall and easy to maintain.
本发明涉及崩塌落石遮挡防护技术领域，且公开了一种适用道路工程崩塌落石的柔性遮挡结构及其施工方法，柔性遮挡结构包括设置于陡立山体坡面对侧的支撑结构，由阵列设置的若干悬臂式支撑桩组成，其顶端设置有连系梁。陡立山体坡面适当部位设置腰梁，通过反向预应力锚索锚固于山体坡面。支撑结构与腰梁间连接柔性遮挡防护网，网面设置在受崩塌落石冲击的建构筑物正上方，并倾向建构筑物外侧；柔性遮挡防护网采用负泊松比锚索材料编织而成，包括若干横向钢绞线和纵向钢绞线，交叉处采用高强十字卡扣件固定。本发明采用上述柔性遮挡结构及其施工方法，突破传统高位崩塌落石防冲击柔性拦挡网的防护能级，具有受崩塌落石冲击后韧性强、易维护的功能。
