钢管混凝土搅拌复合桩技术研究
Research on the Technology of Concrete-filled Steel Tube Mixed Composite Pile
摘要
Abstract
A steel tube concrete mixing composite pile foundation treatment technology is proposed,which is composed of steel tube concrete core piles and surrounding cement soil mixing piles.The composite steel tube concrete core piles with high bearing capacity bear the upper load,and the low-priced cement soil with large diameter around them obtain lateral friction resistance,fully utilizing the characteristics of rigid piles and flexible piles respectively;Simultaneously developed construction equipment and technology for synchronously sinking steel pipes and mixing piles into piles;Composite piles have many advantages,such as reasonable stress,high bearing capacity,controllable quality,simple and fast construction,small machinery,slight disturbance,no pollution,low noise,low cost,high efficiency,good adaptability,etc.关键词
