Model: S-812 micro crack pressure grouting machine S-812 for structural high pressure chemical grouting, chemical grouting material using a single solution for professional models, there is no need ultra-high pressure pneumatic source, rapid construction. Body lighter, portable and easy to move and effort. Structural design science simple, no special training to maintenance, its use of mechanical power, can instantly improve the working pressure, liquid sealing agent can be effective perfusion to 0.1mm fine cracks in the construction efficiency is three times faster than traditional technology above, the effect is more lasting and effective water stanch. Is the construction, underground engineering, hydraulic engineering, environmental engineering, municipal, subways, tunnels, culverts works only seepage plugging construction, crack reinforcement device of choice, is a professional construction for sealing the best option. I. Features 1. Environmental protection: Good mechanical performance, no noise, no pollution. 2. Portable: small size, light weight, easy to carry, easy to operate. 3. Efficient: advanced technology, saving time, effort, and high efficiency. 4. Security: technology is reliable, reasonable structure, safe to use. 5. Pressure continued: continued high pressure can be effective agents in the concrete structure micro-gap, slit, porous, capillary fill plug. 6. Structure destructive: installed directly on the concrete crack grouting packers, do not tick tank, not buried on the structure of non-destructive. 7. with water plugging: a variety of slot leakage, cellular leakage, ground water, grouting plugging directly with water. The slurry can effectively inject deep into cracks. 8. supporting the use of a wide range of material: polyurethane, epoxy resin, acrylic resin and other non-granular materials with low viscosity slurry can be used. 9. Multifunctional: a machine, plugging grouting, consolidation grouting, grouting cracks reinforcement. 10. Durable: body parts are not deformed. Maintenance is simple, easy maintenance, durable, easy to clean. Second, the performance indicators of flow: 0.7L / min Weight: 6.5kg Motor power: 500W single-phase AC: 220 V / 50 Hz three cracks Scope 1. various buildings and underground concrete, expansion joints, construction joints, structural joints plugging seal. 2. Geological Drilling Project drilling Wall plugging reinforcement. 3. hydropower project reservoir dam grouting, plugging cracks in the tunnel, seepage, dam seepage reinforced concrete cracks. 4. Subway, tunnel, culverts, sewage treatment pond, concrete cracks leak water, with water plugging. 5. basements, underground garages, underground passages, concrete cracks leak water, with water plugging. 6. Roof concrete slab crack, wall pipe, wall, leakage of water, with water plugging. 7. Concrete structures, beams, columns, structural cracks board, high-pressure injection of epoxy resin. Fourth, supporting plugging grouting material hydrophilic polyurethane grout, hydrophobic polyurethane grout, pouring concrete cracks with epoxy glue.
