    NAME:  A-8   
     
    Length: 8 cm
    Use drill: 14mm
    Application: basement, roof

    product manual:
    1, high-pressure sealing the needle: the use of loop fastening pressure principle. The head of a one-way valve to prevent the slurry under high pressure to push down spray. Central pressure expansion portion with a rubber tube with a diameter of 13 maps, stuffed pore size of the grouting hole 14MM, and tighten the pressure ring screws, compression rubber casing, so that the mouth fixed in the grouting grouting hole. (Grouting nozzle check valve to pressure to open in 0.4KN or more, so grouting pressure must be higher than the value). High pressure sealing needle There are currently four types: copper mouth, mouth aluminum, steel mouth, the plastic nozzle, the first three for the ring compression. Divided into pre-seal type, that is filling the mouth of the inlet check valve is located at the entrance; after the seal type, namely the feed inlet of the check valve provided at the outlet, depending on the particular situation of choice. Before and after laying a good mouth seal type can be screwed down the front to relieve pressure drainage, to be filling and then screw up; after a good mouth seal type buried, it can not drain relief, but the construction is completed filling the mouth can be dismantled Construction of the next process. Some common rubber seal filling nozzle diameter of 14mm, to be equipped with 14mm drill bit. Dense structure chosen for the length of filling the mouth can 7~8cm; to loose structure, the choice of length 1 (Tl5cm grouting mouth.
    Accessories:
    1, rubber mats: butter head rubber, rubber with special rubber material (can withstand high pressure shocks), in crowded under high pressure without deformation of the rubber head damage caused by drug efflux.
    2. Butter head (excluding the traditional way of consuming spiral hours), compression of up 10000PSI more than four hours claw quick connector province by pharmaceutical extrusion pressure rapidly enlarging rubber, four claws close the filling nozzle attachment inclusion.
    Precautions:
    1 head butter rubber due to the construction process, high pressure and corrosive chemical grouting material, easily damaged. Therefore, in the construction process, damage is found, should be replaced, otherwise lead to leakage of plasma.
    2, at the end of construction, since the cleaning machine with a cleaning agent, for butter head rubber have a corrosive effect, resulting in butter head eraser easily damaged, so at the next construction, should be replaced.
    Construction steps:
    1, looking for cracks: For wet grass, sweeping the first knot water until all clean grass, the surface is slightly dry, carefully looking for cracks, along with a color pen or chalk crack well marked; For dry grass, clean up after the pump or blower available blowing dust on the surface.
    2, drilling: press thickness of the concrete structure, crack *** in the lower left or right tilt 5CrrTlOcm at half deep drilling to the thickness of the structure, the lower sequential uphill drilled by the drill to stop at again after laying water needles, crack the case due to the general structure irregularity, it shall pay particular attention to both sides along the crack direction cross-drilled when drilling. Pitch should the actual situation may be, to the last two holes in grout cracks can interchange principle, at the beginning of the general pitch is 25CrrT30Cm appropriate; pore size, should be supporting the sealing needle the size of the , using a non-target 13mm drill bit. Holes and cracks section should cross 30 degrees ~ 50 degrees, and 1/3 cross the floor in the middle of the range.
    3, buried the needle sealing: sealing the needle to supporting parts, is injected into the slurry inside the connecting member fracture, when embedded application tools are tight, and to ensure that the rubber part of the needle and the hole wall is not used before drying, otherwise tighten When prone to slipping.
    4, seepage / reinforcement at drilling, locking the needle, the medicine poured into the cup, turn on the power switch, the cup and tube extrusion residual cleaner or lubricant until agents sprayed up, and then insert the needle, The drug injected into the wall of the body, stanch, reinforcement.
    Application range:
    1. The Subway, tunnel, culverts, sewage treatment pond, concrete cracks leak water, with water plugging.
    2. basements, underground garages, underground passages, concrete cracks leak water, with water plugging.
    3. round roof slab crack, wall pipe, wall, leakage of water, with water plugging.
    4. Concrete structures, beams, columns, structural cracks board, high-pressure injection of epoxy resin.
    5. Secondary seams, cracks, etc. seepage stanch top Sakamoto, beams, walls.
