What Should Be Paid Attention to in UHPC Construction?

UHPC construction requires attention to key aspects such as substrate preparation, installation precision, joint sealing, and curing protection—any oversight may affect the final result. Based on 28 years of construction experience, Qinglong Group has summarized a four-step method of survey and layout, substrate preparation, panel installation, and sealing treatment, ensuring construction quality through refined management.

Substrate preparation is the foundation of construction. Flatness deviation must be ≤4mm/2m, and strength must meet standards. Qinglong Group inspects the substrate before construction, repairing or reinforcing any non-conforming areas. Waterproofing treatment must not be overlooked to prevent moisture erosion. Survey and layout must be precise, using a total station with errors controlled within ±3mm. These preparations create the conditions for installation.

Panel installation requires careful operation. Professional lifting devices are used to avoid damage. Hanger point spacing follows the design, typically 600-800mm. Qinglong Group performs real-time corrections during installation to ensure flatness. Joint width is calculated based on thermal deformation, with expansion space reserved. Sealing materials should be products with good elasticity and strong durability to ensure long-term watertightness.

Curing protects the construction results. After installation, avoid impacts and conduct regular inspections. Qinglong Group provides detailed guidelines to help customers with maintenance. Scientific construction ensures project success.
