Segmented grouting anchoring method for joint development high and steep rock slope
The invention relates to the technical field of geotechnical engineering, in particular to a segmented grouting anchoring method for a joint development high and steep rock slope. According to the segmented grouting and anchoring method for the joint development high and steep rock slope, strong combination of grouting and anchoring is achieved, a steel expansion shell can stabilize a shallow rock-soil body and can stabilize a grouting pipe, an annular PN water stop ring which expands when meeting water is adopted, a foundation is laid for improving the grouting pressure through the effective blocking effect, and the grouting efficiency is improved. Therefore, the grouting quality is ensured, and the reinforcement and reconstruction effect is greatly enhanced; the structure is easy to install and operate and low in cost.
本发明涉及岩土工程技术领域，具体一种节理发育高陡岩质边坡分段注浆锚固方法；本发明提供了一种节理发育高陡岩质边坡分段注浆锚固方法，实现了注浆与锚固的强强联合，钢制涨壳不仅可以稳定浅部岩土体还可以稳定注浆管，且采用环形PN遇水膨胀的止水环，有效的阻隔效果为提高注浆压力奠定了基础，从而保证注浆质量，大幅增强加固改造效果；本结构安装、操作简单，成本低。
