Microbial grouting anchoring method for grouting in cavity and microbial grouting anchoring structure
The invention discloses a microbial grouting anchoring method for grouting in a cavity and a microbial grouting anchoring structure. The method comprises the following steps that an anchoring base body is drilled, multiple sets of grouting pipes are installed in a cavity of a hollow anchoring rod, part of the grouting pipes extend to the bottom of the cavity, part of the grouting pipes extend outof the hollow anchoring rod from a side hole in the middle of the hollow anchoring rod, and the hollow anchoring rod is inserted into a drilled hole; grouting liquid is injected into the drilled holethrough the grouting pipes; and a fixed object is installed at the side wall of the anchoring base body, a nut is installed on the hollow anchoring rod, and anchoring is completed.
本发明公开了一种腔内灌浆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，将多组灌浆管安设于空心锚固杆的空腔内，其中部分组灌浆管延伸至空腔底部，部分组灌浆管由空心锚固杆中部的侧孔延伸至空心锚固杆外，再将空心锚固杆插入钻孔内；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，在空心锚固杆安装螺帽，完成锚固。
