Shallow-layer anti-scouring and deep-layer anti-sliding supporting device and method for granite residual soil slope
The invention discloses a shallow-layer anti-scouring and deep-layer anti-sliding support device for a granite residual soil side slope, which comprises a lattice beam reinforcing structure arranged on the surface of the side slope, a rotary jet grouting anchor cable anchored in the side slope and fixedly connected with the lattice beam reinforcing structure, and an FRP (Fiber Reinforce Plastic) rib sleeved in the rotary jet grouting anchor cable and fixedly connected with the lattice beam reinforcing structure, and injecting the MICP bacterial liquid and the nutrient solution into the granite residual soil of the side slope through the rotary spraying anchor cable. The invention further discloses a supporting method. The rotary spraying anchor cable is adopted to conduct MICP treatment on the granite residual soil side slope, MICP bacterial liquid and nutrient liquid can evenly permeate into surrounding granite residual soil bodies conveniently, the strength of the surrounding soil bodies can be better improved, the FRP rib is arranged in the rotary spraying anchor cable in a sleeved mode, the FRP rib and the rotary spraying anchor cable are anchored together, the anchor cable high in resistance and long in service life is formed, and the service life of the anchor cable is prolonged. The anchor cable has better anchoring anti-sliding performance, and the anchoring force needed by deep sliding of the anchor cable is improved.
本发明公开了一种花岗岩残积土边坡的浅层抗冲刷深层抗滑移支护装置，包括设于边坡表面上的格构梁加固结构，锚固于边坡内且于格构梁加固结构固定连接的旋喷锚索，套设于与旋喷锚索内且与格构梁加固结构固定连接的FRP筋，以及通过旋喷锚索向边坡的花岗岩残积土内灌入MICP菌液和营养液。本发明还公开了一种支护方法。本发明采用旋喷锚索对花岗岩残积土边坡进行MICP处理，极大地方便MICP菌液和营养液均匀渗入周围花岗岩残积土土体，能更好地提高周围土体强度，并且通过将FRP筋套设于旋喷锚索内并将两者锚固在一起，形成高抗力和长寿命的锚索，具有更好的锚固抗滑移性能，提高了锚索在深层滑动需要的锚固力。
