    BluGeo SR Rock Bolt is grouted with BluCem HS400 Thixotropic Cementitious Grout.



    1.1 Position the bolting machine into the position and angle specified.
    1.2 Using a 45mm bit, drill to a depth equivalent to the length of the BluGeo SR Rock Bolt.
    1.3 Flush and air blow the drilled hole until the flushing water returns clear, and remove the extension drill steels.


    2.1 Check for correct hole depth. This is best done using conduit marked at the correct length. Ensure the hole has been flushed of all loose material so there is no breakage in the sheathing when inserted.
    2.2 Place the specified dolly into the drill chuck
    2.3 Load the BluGeo SR Rock Bolt onto the Jumbo boom, Shell end first – DO NOT grip the BluGeo SR Rock Bolt with any gripper jaws as the sheathing could be cut. The bolt can also be inserted by hand into the hole. Ensure a holding brace is used to keep the bolt in the hole when inserted vertically into roof.
    2.4 Place the drive end of the BluGeo SR Rock Bolt into the drive mechanism in the base of the dolly. Rotate the BluGeo SR Rock Bolt nut to ensure it is engaged into the drive mechanism.
    2.5 Take the bolt up to the level required for the plate to be fixed with cut face or mesh. Spin the BluGeo SR Rock Bolt using maximum rotation. No thrust or feed force at this stage. The expansion shell will expand and grip.
    2.6 The nut and bolt will spin to the end of the remaining thread when the shell engages. This will indicate you have achieved the full preload of the expansion shell.
    2.7 The BluGeo SR Rock Bolt is ready to be grouted.


    3.1 Refer to BluCem HS400 TDS for mixing and pumping instructions.
    3.2 Lay out the grout, mixer, pump and hoses to suit the location of the BluGeo SR Rock Bolt to be grouted. The longest pumping distance for the Thixotropic grout must be kept below 30 metres.
    3.3 Check the mixer and remove any scale/debris.
    3.4 Check that all taps and fittings in the grout line are operational.
    3.5 Place some water into the mixing bowl, test the operation of the mixing paddles and pump this water through to slick the grout lines.
    3.6 Ensure all test water is removed from the mixing bowl before commencing
    3.7 ALWAYS MEASURE the volume of water and add to the bowl.
    3.8 Keep mixing until smooth, lump free slurry is achieved. The consistency should be checked by scooping a level handful with a rubber glove and the grout must not fall off when the hand is turned upside down.
    3.9 Attach the grout line to the lance and run the pump to clear any water through the line until thixotropic grout appears. Turn off the pump ready for filling of BluGeo SR Rock Bolt.
    3.10 Connect the grout lance to the BluGeo SR Rock Bolt, ensuring the lance is screwed on with a complete seal with the nut. If using a Jumbo grouting boom ensure the grout cup is hard against the nut and plate.
    3.11 Keep mixer blades rotating to feed grout into the pump chamber and turn the pressure relief tap to off.
    3.12 Commence pumping until grout appears at the indicator hole in the plate.
    3.13 Release the pressure in the grout line by turning on the pressure relief tap. The grout must not keep running from the hole collar for more than 4-5 drips after the grout line is de-pressurised.
    3.14 Disconnect the grout lance from the BluGeo SR Rock Bolt, being careful of any grout which may drip from above. The grout lance will only rotate/disconnect if the line is de-pressurised.
