Microbial grouting anchoring method with grouting pipes externally mounted and microbial grouting anchoring structure
The invention discloses a microbial grouting anchoring method with grouting pipes externally mounted and a microbial grouting anchoring structure. The method comprises the following steps: drilling holes in an anchoring substrate, installing a solid anchoring rod and grouting pipes in the drilled holes, and enabling the grouting pipes to be disposed around the solid anchoring rod in a surroundingmanner; injecting grouting liquid into the drilled holes through the grouting pipes; and mounting a fixed object on the side wall of the anchoring substrate, installing a nut on the solid anchoring rod, and finishing anchoring. The grouting liquid comprises mixed liquid of a calcium source solution, nutritive salt and bacterial liquid, and during grouting, the mixed liquid of the nutritive salt and the bacterial liquid is firstly injected, then the calcium source solution is injected, and grouting deposition products are formed in the drill holes.
本发明公开了一种外置灌浆管的微生物灌浆锚固方法及锚固结构，包括以下步骤：在锚固基体钻孔，钻孔内安设实心锚固杆和灌浆管，灌浆管环绕设置在实心锚固杆周围；将灌浆液经由灌浆管注入钻孔；在锚固基体侧壁安装被固定物体，在实心锚固杆安装螺帽，完成锚固；其中，灌浆液包括钙源溶液、营养盐和菌液的混合液，灌浆时，先注入营养盐和菌液的混合液，后注入钙源溶液，在钻孔内形成灌浆沉积生成物。
