Secondary Grouting and Curing of Fan Anchor Bolts

Secondary Grouting and Curing of Fan Anchor Bolts

     Perform secondary grouting at fan anchor bolt areas using micro-expansive concrete, and implement standardized curing cycle control to ensure compact and stable fan base foundations. Prevent foundation settlement and loosening, enhance the support rigidity of large rotating equipment bases to counteract vibration loads from long-term high-speed operation, and fundamentally reduce the probability of abnormal noise and misalignment faults during fan operation.
