Microorganism continuous layered mineralization repair method for steep dip non-through microfractures of rock mass
The invention relates to a microbial continuous layered mineralization repair method for a steep dip non-through microfracture of a rock mass, which comprises the following steps of: blocking the surface of the steep dip fracture of the rock mass, embedding a metal rod in the bottom of the fracture, and reserving two unblocked openings in the top of the fracture; injecting the cementing fluid until the cementing fluid is full; injecting the cultured bacterial solution until the injection is full; the cementing liquid is injected into the container, calcium ions and urea in the cementing liquid are diffused into the cracks under the diffusion action under the action of the microporous filter membrane, and the calcium ions and the urea in the cracks are continuously supplemented; connecting the metal rod with a negative electrode, connecting the solution with a positive electrode, and electrifying for a period of time; after electrifying is completed, the fissures are supplemented with fissure bacterial liquid and urea mixed liquid through the needle head; electrifying and supplementing the mixed solution once every 6-48 hours until the crack is completely repaired. The repair method provided by the invention has the advantages of economy, high efficiency, high filling rate, high bridging rate and uniform distribution of mineralized products.
岩体陡倾非贯通微裂隙的微生物连续分层矿化修复方法，包括以下步骤：对岩体陡倾裂隙的表面进行封堵，同时在裂隙底部埋入金属棒，在裂隙顶部预留两个未封堵的开口；注入胶结液直至注满；注入培养好的细菌溶液直至注满；在容器中注入胶结液，在微孔滤膜的作用下，胶结液中的钙离子和尿素通过扩散作用扩散到裂隙内部，对裂隙内部的钙离子和尿素进行连续补充；通入电压，金属棒接负极，溶液接正极，通电一段时间；在完成通电以后，通过针头向裂隙补充裂隙菌液和尿素混合液；通电和混合液的补充每隔6‑48h进行一次，直至裂隙完全修复。本发明提供的修复方法具有经济、高效率、高填充率和高桥接率以及矿化产物能够均匀地进行分布的优点。
