Rock slope reinforcing and greening integrated structure based on MICP and construction method
The invention provides a rock slope reinforcing and greening integrated structure based on MICP and a construction method, and relates to the technical field of slope governance, the integrated structure comprises a grating, ground anchors, a coarse aggregate layer and a greening layer, the grating is arranged on the slope surface of a slope, the frame of the grating is of a hollow structure and is not parallel to the slope bottom of the slope, and an MICP grouting channel is formed in the grating; the anchor nails are used for fixing the grating; the coarse aggregate layer is arranged on the inner side of a frame of the grille and is reinforced through MICP unsaturated grouting. The greening layer is arranged on the surface of the coarse aggregate layer, and an MICP hardened layer is arranged on the surface of the greening layer. The rock slope is repaired in a grid-coarse aggregate layer-greening layer combined reinforcing mode, the unconfined compressive strength of the coarse aggregate layer and the interfacial shear strength between the coarse aggregate layer and the slope are improved through the MICP technology, cementing materials such as cement and concrete do not need to be used, the pollution problem caused when the cementing materials are used for reinforcing is solved, and the service life of the slope is prolonged. And the re-greening layer is not easy to fall off.
本发明提供一种基于MICP的岩质边坡加固复绿一体化结构及施工方法，涉及边坡治理技术领域，所述一体化结构包括格栅、锚钉、粗骨料层和绿化层，所述格栅设置于边坡的坡面，其边框为中空结构，并与边坡坡底不平行，内部设有MICP注浆通道；所述锚钉用于固定格栅；所述粗骨料层设置于格栅的边框内侧，并经过MICP非饱和注浆加固；所述绿化层设置于粗骨料层表面，其表面设有MICP硬化层。本发明采用格栅‑粗骨料层‑绿化层联合加固的方式对岩质边坡进行修复，利用了MICP技术提升粗骨料层的无侧限抗压强度以及与边坡间的界面剪切强度，无需使用水泥、混凝土等胶凝材料，解决了使用胶凝材料加固时带来的污染问题，且复绿层不易脱落。
