What Maintenance Work Is Required for UHPC Components? Full-Cycle Maintenance and Qinglong Group's Service System

The post-installation maintenance system for UHPC components covers three major sections: routine inspection, regular testing, and professional repair, specifically including standardized processes such as quarterly visual inspection, annual performance testing, and a comprehensive evaluation every 5 years. Based on 28 years of project maintenance data, Qinglong Group has established a four-step maintenance method of “monitoring-evaluation-treatment-prevention”. In projects such as the Wuhan Han Show Theatre and Hainan International Convention and Exhibition Center, through drone inspection, optical fiber monitoring, laboratory analysis and other means, maintenance costs have been kept at 1-2% of construction cost per year, far below the 3-5% for ordinary concrete. Scientific maintenance not only keeps UHPC components in optimal condition, but can also extend their service life to more than 60 years, achieving asset value preservation and appreciation.

Daily Inspection Is the Basic Guarantee

Component surfaces are visually inspected monthly for cracks and staining; deformation at key points is measured quarterly (accuracy ±0.1mm). Qinglong Group has developed a mobile inspection APP with data uploaded to the cloud in real time. In the Shenzhen Yirui Biotechnology Building project, regular inspections identified potential problems 3 months in advance, avoiding losses.

Professional Testing Assesses Internal Condition

Rebound method strength testing and carbonation depth measurement are carried out annually; core samples are taken every 3 years for chloride content analysis. Qinglong Group's laboratory provides authoritative test reports to guide maintenance decisions. In coastal projects, the testing cycle is shortened to 2 years to ensure safety.

Combining Repair with Prevention

Cracks are injected with epoxy resin and surfaces are coated with protective agents. Qinglong Group's patented maintenance materials provide long-lasting repair results. Component “health records” are established to predict maintenance needs. Systematic maintenance is the guarantee for maximizing UHPC value.
