Construction Technology for Ultra-High-Strength Prestressed Concrete Pipe Piles
Ultra-high-strength prestressed concrete pipe piles offer advantages such as low cost per unit bearing capacity, strong penetration through soil layers, short construction periods, no pollution, and convenient construction, and are widely used in soft soil, silt, fine sand, medium sand, and other foundation strata. During the construction of ultra-high-strength prestressed concrete pipe piles, quality problems such as pile-top displacement and pile-shaft fracture frequently occur, which not only affect the construction progress and pile stability of ultra-high-strength prestressed concrete pipe piles but also constrain the schedule and quality of the overall building construction. Based on practical work experience, this paper proposes improving the construction quality of ultra-high-strength prestressed concrete pipe piles through design control and construction control.
