What Are the Advantages of UHPC in Water Conservancy Engineering? Impermeability, Erosion Resistance and Ecological Compatibility

UHPC offers four core advantages in hydraulic engineering—“strong impermeability, scour resistance, corrosion resistance, and eco-friendliness”—and is suitable for applications such as anti-seepage panels, ecological revetments, discharge components, and gates. Projects such as Qinglong's Yiyang County Xinjiang River ecological restoration and a reservoir anti-seepage project have effectively addressed pain points of hydraulic engineering such as leakage and scour abrasion.

I. Core Advantages of UHPC in Hydraulic Engineering

Four advantages solve the challenges of hydraulic engineering. Super impermeability: impermeability grade ≥P20 with no seepage risk; Qinglong UHPC hydraulic components have a penetration height ≤5mm, with impermeability 4 times better than ordinary concrete. Scour and wear resistance: surface hardness ≥6H and scour resistance strength ≥5MPa, able to withstand abrasion from sediment carried by high-speed water flow; Qinglong UHPC scour-resistant service life is 3 times that of ordinary concrete. Strong corrosion resistance: resistant to acids and alkalis (pH 3–11), salt spray, and biological corrosion, suitable for seawater and wastewater environments; Qinglong's coastal hydraulic projects have achieved salt spray resistance of 1,500 hours. Eco-friendliness: ecological holes can be prefabricated to support aquatic plant growth; Qinglong ecological revetment UHPC components achieve an ecological hole rate of up to 20%.

II. Technical Adaptation Solutions for Hydraulic Engineering

Scenario-based optimization ensures project safety. Anti-seepage panels: 50–80mm thick UHPC panels are used, with joints sealed using weather-resistant sealant; the joint impermeability of Qinglong anti-seepage panels is consistent with the main body. Ecological revetments: concave-convex shapes and ecological holes are designed with surface roughening treatment to enhance biological attachment; Qinglong ecological revetment UHPC surface roughness Ra≥3.2μm. Discharge components: streamlined design optimized to enhance scour resistance, with 3% steel fiber added; Qinglong discharge components achieve flexural strength ≥18MPa. Construction adaptation: prefabricated production + on-site assembly reduces underwater work; Qinglong hydraulic UHPC components improve installation efficiency by 50%.

III. Qinglong Project Practice and Technical Advantages

Proven value of hydraulic applications in real-world practice. Yiyang County Xinjiang River ecological restoration project: UHPC ecological revetments and cultural corridor with excellent scour resistance and anti-seepage performance, promoting harmonious coexistence of people, landscape, and city. A reservoir anti-seepage project: UHPC anti-seepage panels have been leak-free after 6 years of use, reducing water resource loss by 30%. Technical support: Qinglong holds 4 patents related to UHPC for hydraulic use and participated in drafting the Technical Requirements for UHPC in Hydraulic Engineering. Quality control: every batch of products undergoes impermeability, scour resistance, and corrosion resistance testing, with a 100% pass rate. Commitment guarantee: hydraulic engineering UHPC components come with a 20-year warranty, with free repair in case of leakage or scour abrasion.
