Gaoyou professional plugging the unit you are welcome Jiangsu large plugging Welcome: National Free plugging Hotline: 13961999789 a mine roadway cause of the cracks (1) After the construction project is exposed to the atmosphere, causing local damage of concrete carbonation; (2) plugging mine tunnel, mine tunnel seepage, plugging mine tunnel waterproofing, corrosion plugging mine tunnel, mine tunnel chemical grouting plugging; (3) concrete construction joints opened; the impact of (4) and groundwater rock bound water Nullah and spillway weir on the right bank of the retaining groove joints and cracks caused by water seepage; two, a treatment program, seepage joints (joints and cracks): Requires Water Seepage in the side seam drilling hammer slant-hole and seam intersection, irrigation KLY-G3-soluble polyurethane, the slurry gel time is adjustable, it reacted with water to produce elastic gel plug leaks, can adapt to seasonal changes in the seam, the performance indicators in Table. 2, the general dry cracks and construction joints: Requires reinforcement in slant-hole hammer drilling seam side seam intersection and closed cracks along the crack brushing dilute epoxy clay, after curing, by drilling irrigation KLY-G1 type epoxy fill strong grout, the performance indicators in Table 1. 3, through the cracks left chamber floor and basement connected, arranged in two rows inclined hole depth, deep irrigation KLY-G3-soluble polyurethane to fill the fractured bedrock channel blockage; shallow hole irrigation KLY-G1 epoxy reinforcing slurry reaches internal porosity of concrete filling, bonding cracks and restore the structure as a whole. Grouting materials and the corresponding technical indicators index material KLY-G3 KLY-G1 Viscosity (cps) from 40 to 80 1.8 to 2.5 specific gravity (g / cm3) 1.05 ~ 1.1 1.03 ~ 1.07 adhesive strength (Mpa) 1 ~ 1.8 1.7 ~ 1.9 Compressive Strength (Mpa) 80 ~ 100 Tensile strength (Mpa) 12.5 ~ 14.8 impermeability S15 S15 Elongation (%) 300 expansion rate (%) ≥350 toxic toxic polymer nontoxic polymer characteristics cured water reaction, the curing time is adjustable between several tens of seconds to several minutes. Consolidation body has good elasticity, water expansion. Suitable for filling joints, cracks seepage seam according to the type of preparation of the appropriate size. Can be used in wet grout joints. This grout is better hydrophilic, high consolidation strength, are reinforcing materials. Advantages and disadvantages of one-component material, easy to use, the infiltration. Water Seepage viscosity suitable for small, infiltration, high strength of the cured product is suitable for minor cracks grouting reinforcement. Third, the construction 1. After Chiang Khong, a small hole to insert a special dedicated grout plug, connect the pump before filling the pipeline; 2, filling the bottom-up approach, a single solution method, each hole perfusion; 3, filling Pressure control: Regardless of grouting, grouting pressure and the need to control the rate at the start into the pulp. For expansion joints, filling open until after slurry sealing sheet bypass leakage slurry after the initial setting, grouting pressure to improve 1mpa, for construction joints and cracks, using progressively boost control structure designed to allow grouting pressure is lower than the maximum pressure, general control in 1.0 ~ 1.5mpa; 4, the end of the standard: whether it is impervious or reinforced grout joints should be done within the slurry filled full to surface and adjacent holes after sewing a slurry, to design grouting pressure, pressure grouting 20 minutes; 5, after the completion of an inspection area filling, using grinder grinding ,, clean after brushing modified grout, improve the treatment effect, play a protective role to achieve similar color and concrete. IV Conclusion Our professional commitments do basements, tunnels, subways, culverts, dams, reservoirs, acid, alkali, salt pond, power plant cooling tower leak point, seam leakage, cable channel, pump valves caisson, mine, mine tunnel plugging mine tunnel seepage, plugging mine tunnel waterproofing, corrosion plugging mine tunnel, mine tunnel chemical grouting plugging, plugging oil depots and other projects. Plugging process: 1, waterproof plugging underground grouting is our specialty polymer formulations, based on a variety of chemical materials, according to a certain proportion of the size of the water pressure made A, B two liquid viscosity of water is almost the same, good permeability can be injected into the 0.1 mm slit in the concrete under pressure and very humid environment quickly gather. 2, setting time can be accurately controlled with the ratio within a few seconds or a few minutes, the rapid condensation of pressure in the water velocity, water flow and more cases. 3, good permeability, water swelling after drying shrinkage, insoluble in water, kerosene, gasoline and other organic solvents, acid, alkali, bacteria Erosion from atmospheric conditions also after, there is a certain strength, flexibility and change pressure, shelf use more than a decade. 4.
