Description: the grout plug my company based on the actual situation of late at home and abroad in the 1990s grouting, after a large number of tests, well-developed case of the most advanced multi-purpose deep hole grouting blocking equipment is widely used in water conservancy fracturing, grouting coal mine iron ore gas drainage. use, connect all piping systems, tighten all threaded, turned on the gas source (or hydraulic pump) on the orifice (or closed at one end of the steel pipe, grout plug within) pressure test, check the joints for leaks into the hole spare. 2, opening the cylinder valve or the hydraulic pump, so that the grout plug slowly swelling, attention pneumatic pressure must be greater than 2/3 of the grouting pressure reaches a predetermined pressure to the grout. Grouting beginning, to be back to the pulp mouth large number of slurry beneficial subdivided times slow pressurized to a predetermined grouting pressure, or easy to form a larger pressure differential. Grout should always check the cylinder pressure relief valve pressure gauge pressure, such as the reduction should be instant plus complement. Grouting longer must check for channeling pulp around the plug return slurry phenomenon, grouting, if any, should be stopped, let go of stress, inflatable plug loose look up and down, to prevent the inflatable plug is consolidation, and is difficult to remove. 5, the end of the grout must first let go grouting pressure, and then let go of the inflation pressure, do not be the first to let go of the inflation pressure, prevent grout plug injection, resulting in security incidents. 6 after grouting, simply grouting plug into the steel tube closed at one end, inflatable approximately 0.5Mpa can rinse cycle. 7, the the grout plug is removed, the pipe with the slurry into the tube back to the slurry pipe connected flush. 8, porous with grouting, all piping must be parallel row, shall not be twisted together to prevent a Fasheng accident affecting the safety of the other holes. 9, after prolonged use, the lower end of the grout plug should be apart for cleaning, butter. 10 drill holes found long fissure than crushing may occur channeling pulp around the plug back to the pulp should also put a trachea to the top of the grout plug, if any, channeling pulp around the plug back to the pulp with a high-pressure gas-flush, can prevent the jam. Second, the technical parameters: sealing diameter 30-120mm (processing) work according to user demand pressure 1-8MPa (processing) and safety valve to start the flow of pressure 0.4-0.5MPa according to user demand per hour water injection 4-4.5 tons sealing compressive strength test pressure (Mpa) burst pressure in the free state of the depth of 1-8m Model Diameter (mm) expansion of the scope of the free state applicable aperture (mm) (mm) Working pressure ≤ (Mpa) state φ32-2 50 ± 2.0 90 +8-4 60 6 12 24 φ38-2 55 ± 2.0 95 +8-4 65 5 10 20 φ45-2 63 ± 2.0 100 +8-4 75 4 8 16 φ45-4 69 ± 2.0 100 +8-4 75 16 24 32 φ51-2 69 ± 2.0 110 +8-4 90 4 8 16 φ51-4 75 ± 2.0 110 +8-4 90 16 24 32 φ64-2 84 ± 2.0 120 +8-4 100 3 6 12 φ64- 4 90 ± 2.0 120 +8-4 100 8 12 16 φ76-2 94 ± 2.0 130 +8-4 110 3 6 12 φ76-4 99 ± 2.0 130 +8-5 110 8 12 16 φ89-2 109 ± 2.0 140 +8-5 130 3 6 12 φ102-2 122 ± 2.0 160 +8-5 150 3 6 12
