HE JUNMING / LIU DAN / LI WENBIN / XIONG LEI / XU QING

The invention discloses rock slope filling closed protection and a construction method, and belongs to the technical field of rock mass repair. The rock slope filling closed protection comprises a slope cavity reinforcement cage placed in a slope cavity, and an anti-floating anchor rod arranged at the bottom of the slope cavity in a driving mode. The front end of the anti-floating anchor rod goesdeep into rock at the bottom of the slope cavity, and the tail end of the anti-floating anchor rod is connected with the slope cavity reinforcement cage. Foam concrete is poured into the slope cavity.A steel wire grid net, an anti-seepage geomembrane, a cushion layer and a cast-in-place concrete lining protection slope are sequentially laid at an end opening of the slope cavity and on a rock slope. According to the rock slope filling closed protection and the construction method, the construction difficulty of rock slope filling protection can be lowered, the collapse risk of the rock slope with the cavity is reduced, and the construction quality and construction efficiency of rock slope lining construction are improved.

本发明公开了岩质边坡填充封闭防护及施工方法，属于岩体修复技术领域。本发明包括放置在边坡空腔内的边坡空腔钢筋笼，以及打设于边坡空腔底部的抗浮锚杆，抗浮锚杆的前端深入边坡空腔底部的岩石中，尾端连接边坡空腔钢筋笼，边坡空腔内浇筑有泡沫混凝土，边坡空腔的端口以及岩质边坡上依次铺设钢丝格栅网、防渗土工膜、垫层和现浇混凝土衬砌护坡。本发明可以降低岩质边坡填充防护的施工难度、改善带空腔岩质边坡危的崩塌风险、提高岩质边坡衬砌施工的施工质量和施工效率。
