Chemical grouting is the use of manual or mechanical means, carry on with water plugging, under pressure, the special of the filling material is poured into the cracks in the structure of the building, so that cracks in the grout material solidifies in order to achieve the filling cracks and sealing purposes. Right through the cracks, you can take the sealed seam pipe, irrigation methods of treatment. Non through the cracks, because the relationship between breath, difficult to crack the slurry irrigation district steeple, and thus can not eliminate the stress concentration area formed by the tip region, so treatment should carefully consider various factors, improving slurry filling rate. For temperature crack, taking into account the temperature of the concrete building on the "lag effect", usually selected at low temperature of the concrete grouting plugging leaks water, the better. . Grouting is a new chemical grouting plugging technology, which uses double grouts. Proportionally weighed three materials add water and stir into liquid A pro rata weighed B desulfurization add water and stir into the liquid, when the two liquids mix after polymerization reaction, the initial setting of 30 seconds, 2-3 minutes, the reaction is complete, the final cemented colloids. Grouting injection structure layer using a water-soluble form, low slurry viscosity, permeability, can be injected into the cracks of 0.1mm or less; slurry in the wet, the water speed large, multi-criteria aggregation under water; gel also has good permeability, the case expansion of water, corrosion resistance and other characteristics, colloidal compressive 0.01-0.06MPa, tensile strength 0.02-0.04MPa. b. grouting method is mainly used in a large amount of water leakage, water dispersion, is not conducive to sealing cracks and individual water points, faces. According to determine the location of the crack closure status. Internal grouting to seal the water channel and cracks, or water flow is relatively concentrated, easy to block. Leakage greater than 150mL / min centralized water points, using water shutoff grouting method. The first point on the water drilling, drilling depth to not penetrate the structure layer, preferably not less than 20cm, both to avoid slurry hyperdiffusion phenomenon, but also to clear the water around the point when the deep-rooted minor fissure grouting, play relief role. Then float hole gravel ballast clean up mud to gel with the speed of 25mm outer diameter plastic hose buried water hole, then trim mortar mouth.
