  • Coal seam reinforcement hole sealer

    I. Application It is suitable for plugging of coal or rock body during and after liquid injection and water injection. 2. Structure The hole sealer is composed of Takano expansion hose, safety valve, quick joint and skeleton steel pipe. 3. Technical parameters Working pressure: 5——8Mpa Sealing range: 45mm—120mm Application range: Can transport mixed resin, water, cement and other media Connection: M20X1.5 The company can design according to the actual diameter of the plugged hole. Processing hole sealer. 4. Method of use 1. It is quick and easy to use the hole sealer. Insert the hole sealer completely into the borehole, connect the hole sealer to the pressure source, and start the pressure. When the pressure is increased to 0.4Mpa, the hose is completely expanded to seal the hole. At this time, the safety valve is opened, and water or grout is injected into the coal body. After the water injection or grouting is completed, it is only necessary to unscrew the connecting pipe connected to the plugging device counterclockwise, and the plugging device remains in the expanded state in the borehole for long-term plugging. It can effectively ensure that the water or slurry in the borehole of the coal or rock body does not flow back. 2. Sealer shrinkage: When water is used as a pressure medium, a suction pump is required; compressed gas can be discharged from the supply pipe.
