When construction personnel arrive at the work site, they should inspect the work area to ensure it is in a safe condition and conduct a thorough inspection of the support structure to confirm its stability. Any loose rocks or cracks should be promptly removed or reinforced. During construction, the condition of the support structure should be subject to regular and irregular inspections. In areas with poor geological conditions, a dedicated person should conduct inspections at each shift.
Anchor rod temporary scaffolding should be securely installed.
If wind, water, or material supply pipeline blockages or ruptures occur during operations, the supply of wind, water, and materials must be stopped in sequence.
If monitoring and measurement of the anchor rod support system reveals deformation, cracking, or other hazards, remedial measures should be taken. In case of an emergency, personnel should be evacuated from the danger zone.
During drilling, carefully control drilling parameters and maintain a reasonable drilling speed to prevent common issues such as drill bit burial, drill bit jamming, hole collapse, bit loss, and neck shrinkage. In the event of an accident inside the hole, promptly address the issue and ensure the availability of necessary accident response tools.
