The invention discloses a loess stratum variable cross-section steel pipe static pressure pile construction method. The method comprises the steps that firstly, a pile pressing area is excavated; 2, pile pressing operation is conducted on the variable-cross-section steel pipe static pressure pile; thirdly, the variable-cross-section steel pipe static pressure pile is poured; fourthly, supplementing piles are installed, and foundation dragging and replacement are conducted on the foundation; and fifthly, the pile pressing area is backfilled. The variable cross-section steel pipe static pressure piles are arranged under the foundation, the pile pressing resistance in the construction process of the steel pipe static pressure piles is reduced, and therefore construction of the steel pipe static pressure piles is facilitated, the foundation of an existing building is reinforced, effective supporting for the building foundation is formed, and the variable cross-section steel pipe static pressure piles are conveniently connected through the connecting pieces; and the axes of the steel pipe static pressure piles are ensured to coincide during sectional pile pressing, so that the angle deviation of the steel pipe static pressure piles in the pressing process is avoided, the operation is simple and convenient, and the practicability is high.
本发明公开了一种黄土地层变截面钢管静压桩施工方法，包括步骤：一、开挖压桩区；二、对变截面钢管静压桩进行压桩作业；三、浇筑变截面钢管静压桩；四、安装补充桩并进行地基基础拖换；五、压桩区回填。本发明通过在基础下设置变截面钢管静压桩，降低了钢管静压桩施工过程中的压桩阻力，从而有利于钢管静压桩的施工，加固了既有建筑物的地基，形成对建筑物基础的有效支撑，通过设置连接件，便于连接变截面钢管静压桩，确保了分节压桩时钢管静压桩的轴线相重合，从而避免了下压过程中钢管静压桩的角度发生偏移，操作简单、便捷，实用性强。
