What Are the UHPC Casting Methods? Applicable Scenarios and Construction Techniques

UHPC pouring methods fall into three main categories: "mechanical pouring, manual pouring, and spray pouring." The choice depends on component shape, size, and project volume. Qinglong customizes pouring plans based on project requirements, achieving efficient pouring in projects such as Shenzhen Yirui Biotech and the Guangxi New Media Center.

I. Mainstream Pouring Methods: Characteristics and Applicable Scenarios

Each of the three methods has its own advantages. Mechanical pouring: uses concrete pumps or placing booms, highly efficient (5-10m³ per hour), suitable for large-area, standardized components. Qinglong applied this method to the 12,000㎡ exterior wall of the Yangshengtang Pharmaceutical project, shortening the construction period by 30%. Manual pouring: poured into molds by hand, suitable for small components and complex shapes. Qinglong applied this method to the sculptural detail areas of the Shanghai Astronomy Museum, achieving a shape fidelity of 98%. Spray pouring: sprayed onto the substrate under high pressure, suitable for curved and thin-walled components. Qinglong applied this method to parts of the double-curved exterior wall of the Guangxi New Media Center, achieving an adhesion rate of 99%.

II. Construction Techniques for Pouring Methods

Key techniques improve pouring quality. Mechanical pouring: distribute material evenly and avoid concentrated accumulation; Qinglong keeps placement spacing ≤500mm to prevent slurry segregation. Manual pouring: pour in layers (each layer ≤30mm) with vibration using a poker vibrator; Qinglong's manual pouring vibration time is 30 seconds per layer, leaving no air bubbles. Spray pouring: spray distance of 30-50cm at an angle of 45°-60°; Qinglong controls spray pressure at 0.4-0.6MPa to avoid rebound. Mold treatment: apply release agent to molds before pouring; Qinglong's dedicated release agent ensures smooth component surfaces with damage-free demolding.

III. Qinglong's Pouring Optimization Solutions: Customized Efficiency

Pouring efficiency is optimized according to project needs. Shape matching: flat components use mechanical pouring, while special-shaped components use a "mechanical + manual" combination. Qinglong adopted the combined approach for the double-curved curtain wall of the Hainan Poly Peninsula No.1 project, balancing efficiency and quality. Scale matching: large-area projects are poured in zones to avoid initial slurry setting; Qinglong poured the Shenzhen Yirui Biotech project simultaneously in 3 zones. Technical support: BIM simulates pouring routes to avoid clashes in advance; Qinglong's pouring plans achieve a 98% first-pass approval rate. Quality control: 100% compactness inspection after pouring; Qinglong uses ultrasonic testing, with a compactness compliance rate of 100%. Choosing the right pouring method, combined with guidance from a professional manufacturer, can greatly improve UHPC construction efficiency and quality.
