The main construction of the technology; the process comprises the following steps: firstly, treating the surface of a crack, and secondly, sealing the crack; embedding a grouting nozzle, fourth grouting, fifth grouting, and post-treatment, wherein the post-treatment comprises grouting nozzle removal after slurry solidification, crack repairing glue sealing on the surface and the like.

When the wall crack is grouted in a construction process, when holes are drilled, the conventional method comprises the steps of drilling slurry holes at intervals below and above the height direction of the crack, wherein the slurry holes are distributed on two sides of a sealed crack alternately, and the slurry holes need to extend into the crack when the holes are drilled, and the drilling mode of a 45-degree angle is preferably adopted. In particular, the grouting method of the non-toxic low-viscosity high-strength epoxy-based chemical grouting material disclosed in the patent application 201610665278.X comprises the following steps: 1) cleaning dirt on the surface of the crack to enable the crack to be communicated, 2) arranging grouting holes, 3) sealing the surface of the crack, and 4) sequentially grouting at low pressure from bottom to top until all grouting holes are full.
