Flexible interception structure suitable for falling rock impact of near structure and construction method
The invention relates to the technical field of collapsed rockfall protection, and discloses a flexible interception structure suitable for rockfall impact of near structures and a construction method.The flexible interception structure comprises a plurality of I-shaped steel supporting columns, flexible interception nets are arranged between the I-shaped steel supporting columns, and the bottoms of the I-shaped steel supporting columns are fixed to the ground through steel floral tube group piles; the I-shaped steel supporting columns are connected with a mountain through the multi-direction pre-stressed anchor cable structures. The I-shaped steel supporting column comprises a vertically-arranged lower supporting column and an obliquely-arranged upper supporting column, and the flexible intercepting net comprises a plurality of transverse NPR steel strands and longitudinal NPR steel strands which are perpendicularly arranged in a crossed mode. According to the flexible intercepting structure and the construction method, the transverse steel strands and the longitudinal steel strands which are perpendicularly connected in a crossed mode are arranged between the I-shaped steel supporting columns, the flexible intercepting net is formed, impact of mountain high-position falling rocks on adjacent structures can be effectively prevented, and the situation that the structures are damaged after collapsed falling rocks climb over the flexible intercepting structure is avoided.
本发明涉及崩塌落石防护技术领域，且公开了一种适用于近构筑物落石冲击的柔性拦截结构及施工方法，柔性拦截结构包括若干工字钢支撑柱，工字钢支撑柱之间设置有柔性拦截网，工字钢支撑柱底部通过钢花管群桩固定在地面上，工字钢支撑柱通过多向预应力锚索结构与山体连接；工字钢支撑柱包括竖直设置的下部支撑柱与倾斜设置的上部支撑柱，柔性拦截网包括若干垂直交叉设置的横向NPR钢绞线和纵向NPR钢绞线。本发明采用上述柔性拦截结构及施工方法，通过工字钢支撑柱之间设置垂直交叉连接的横向钢绞线和纵向钢绞线，形成柔性拦截网，能够有效防护山体高位落石对临近构筑物的冲击，避免崩塌落石翻越柔性拦截结构后对构筑物造成破坏。
