Chemical grouting is the use of manual or mechanical means to conduct with water plugging, under pressure, will be a special chemical grouting material poured into the cracks in the building structure, so that cracks in the grouting material solidified in order to achieve filling cracks and sealing purposes. Right through the cracks, can be taken seal joints, pipe, irrigation methods of treatment. For non-through cracks in the relationship because of breath, difficult to crack the slurry irrigation steeple area, 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 the temperature cracks, taking into account the concrete building on the temperature "lag effect", usually selected in the concrete body temperature lows grouting plugging leaks in water treatment, the better. . Grouting is a new chemical grouting plugging technology, which uses double grouts. Proportionally weighed three materials made from A fluid mixing water in proportion weighed Sulfur add water and stir into B fluid, when the two liquids mix after the polymerization reaction, the initial setting of 30 seconds, 2-3 minutes the reaction is complete, the final cemented colloids. Grouting injection structure layer using water-soluble form, low slurry viscosity, permeability, can be injected into cracks 0.1mm or less; slurry in the wet, the water speed large, multi-criteria under water condensation; gel also has good permeability, the case Water expansion, 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, face. Crack sealing position is determined according to the situation. Internal grouting to seal the water channel and crack, or to make the water flow is relatively concentrated, easy closure. Leakage greater than 150mL / min, concentrated effluent point, grouting method using water shutoff. The first point on the water drilling, drilling depth so as not to penetrate the structure layer, preferably not less than 20cm, so can avoid slurry hyperdiffusion phenomenon, but also to clear the water points around the deep-rooted fine cracks appear when grouting, play relief role. Then float hole gravel ballast clean up mud with speed to the outside diameter of 25mm gel plastic hose buried water hole, and then trimming the mouth of the mortar. Jiangsu large waterproof plugging company is waterproof sealing technology research and development, one of the construction of an integrated enterprise. Has many years of experience in construction in recent years, the introduction of foreign advanced technology and high-performance waterproof plugging special hydraulic grouting equipment, imported high-tech nano micro molecular waterproof materials, new technology formulated scientific precision grouting plugging the buck, and efficient Plugging technological innovation, professional management of various underground leakage joints, especially for large volume concrete cracks, tunneling, settlement leakage has many years of experience in maintenance treatment, complete with the ability to tough waterproof plugging!
