Large-diameter composite socketed pile and construction method thereof
The large-diameter composite socketed pile comprises a steel bar foundation and a concrete layer poured on the steel bar foundation, the steel bar foundation comprises an end bearing steel bar component and a plurality of steel bar cage components, and the end bearing steel bar component and the steel bar cage components are connected and fixed through steel bar binding hoops; a supporting steel column is arranged between the end bearing steel bar component and the steel bar cage component and fixedly connected with the end bearing steel bar component and the steel bar cage component, the lower end of the supporting steel column extends out of the bottom end of the end bearing component, the end bearing steel bar component is composed of a lower steel bar cage and an expanded-base supporting part, and the expanded-base supporting part is fixedly connected with the steel bar cage through a connecting part. The supporting steel column is struck by external force, so that the supporting steel column is hammered into the soil body or the rock foundation, the two sides of the expanded base supporting part are driven to expand outwards, and the expanded base supporting part in the expanded state is in a conical shape.
本发明公开了一种大直径复合式嵌岩桩，包括钢筋基础和浇筑于钢筋基础的混凝土层，所述钢筋基础包括端承钢筋构件和多个钢筋笼构件，所述端承钢筋构件与钢筋笼构件之间通过钢筋扎箍连接固定，端承钢筋构件和钢筋笼构件中间处设有支撑钢柱并与其固定连接，支撑钢柱下端延伸出端承构件底端，所述承端钢筋构件由下钢筋笼和扩底支撑部组成，扩底支撑部与钢筋笼通过连接部固定连接，当钢筋基础伸入桩孔内，外力击打支撑钢柱，使得支撑钢柱锤入土体或岩石基础内，并驱动扩地支撑部两侧向外扩张，扩张状态的扩底支撑部呈锥形状。
