Low-pressure stable-pressure microbial grouting device for grotto structural cracks and crack repairing method
The invention discloses a grotto structural crack low-pressure stable microbial grouting device and a crack repairing method, when microbial slurry is injected into a structural crack, a microbial slurry storage device and a pressurizing device outside the crack are matched, so that the slurry in the crack continuously maintains a certain pressure, and the crack repairing effect is improved. The existence of the pressure can promote permeation and diffusion of microorganism slurry in microcracks, on one hand, filling of the slurry at the tip ends of the cracks is achieved, and on the other hand, the permeation and diffusion depth of the slurry in holes in the wall faces of the cracks is increased, so that the grotto structure crack microorganism grouting efficiency and the crack repairing effect are improved.
本发明公开了一种石窟结构裂隙低压力稳压微生物注浆装置及裂隙修复方法，通过对结构裂隙注入微生物浆液时，配合裂隙外部的微生物浆液储存装置以及加压装置，实现裂隙内浆液持续维持一定的压力，该压力的存在可以促进微生物浆液在微裂隙中的渗透扩散，一方面实现裂隙尖端浆液的充入，另一方面提高浆液在裂隙壁面孔隙中的渗透扩散深度，从而提高石窟结构裂隙微生物注浆效率、裂隙修复效果。
