  2. Generally, the cement mortar anchor rod should adopt the threaded steel bar as the anchor rod. The exposed end of the anchor rod should be produced and processed with a standard external thread of 120~150mm, and the standard nut for supporting facilities should be selected; hollow grouting anchor rod

  3. Concrete mix ratio (mass ratio): concrete: sand: water should be 1:1~1.5: (0.45~0.5), the grain size of sand should not exceed 3mm; hollow anchor manufacturer

 

  4. Cement mortar should be used at any time when mixing, the cement mortar mixed once should be used up before initial setting, and the initial setting cement mortar cannot be used;

 

  5. The multi-tube grouting process is used. The grouting pipe should be inserted 50-100 mm away from the bottom of the hole. After the grouting is started, the grouting pipe is continuously sent to the bottom of the hole to make the cement mortar squeeze unnecessary water in the hole. The outside of the hole is formed and then pulled out slowly and quickly with the introduction of cement mortar. The working pressure of grouting is not suitable to exceed 0.4MPa;

 

  6. Use water to moisturize the grouting tank and pipeline when the grouting is just started or stopped halfway for more than 30 minutes;

 

  7. The cement mortar should be inserted into the bolt body immediately after grouting. When the bolt body is inserted into the deep layer of the design scheme, cement mortar must be discharged from the nozzle. If no cement mortar is discharged from the nozzle, the rod should be pulled out and grouted again . The total length of the bonding anchor rod should be grouted and round.
