Design and construction method of variable-diameter concrete-filled steel tube mixing composite pile
The invention relates to a design and construction method of a variable-diameter concrete-filled steel tube mixing composite pile, the variable-diameter concrete-filled steel tube mixing composite pile is designed according to the required pile foundation bearing capacity, the variable-diameter concrete-filled steel tube mixing composite pile comprises a flexible pile and a rigid core pile, the rigid core pile is arranged in the flexible pile, the flexible pile is a mixing pile, and the rigid core pile is arranged in the flexible pile. The rigid core pile is made of steel pipe concrete; the variable-diameter concrete-filled steel tube composite pile is designed in a segmented mode, that is, the variable-diameter concrete-filled steel tube composite pile is divided into a plurality of pile sections in the length direction of a pile body of the variable-diameter concrete-filled steel tube composite pile, the diameters of flexible piles, the diameters of rigid core piles and the lengths of the pile sections are different, and the bearing capacity of all parts of each pile section meets the design requirement for the bearing capacity of a pile foundation. The method has the advantages of being capable of being widely applied to various pile foundation projects and composite foundation projects, reasonable in stress, low in manufacturing cost, free of waste, small in influence on the surroundings, good in environment-friendly effect, good in pile forming effect, short and small in machine tool, easy to construct, high in work efficiency and high in site adaptability.
本发明涉及一种变径钢管混凝土搅拌复合桩的设计施工方法，根据所需的桩基承载力设计变径钢管混凝土搅拌复合桩，变径钢管混凝土搅拌复合桩包括柔性桩和刚性芯桩，刚性芯桩设置在柔性桩内，柔性桩为搅拌桩，刚性芯桩为钢管混凝土；对变径钢管混凝土复合桩进行分段设计，即将变径钢管混凝土复合桩沿其桩身长度方向分为若干桩段，各桩段的柔性桩直径、刚性芯桩直径以及桩段的长度不同，且每个桩段的各部位的承载力均满足桩基承载力的设计要求。本发明的优点是：可广泛应用于各类桩基工程、复合地基工程，其受力合理，造价经济，不产生废弃物、对周边影响小，环保效果好、成桩效果好、机具矮小、施工简单、工效高、场地适应性强。
