This invention belongs to the field of engineering machinery technology and relates to a construction method for a variable-diameter drilling and reaming integrated pile driver. It solves the problem that existing drilling and reaming integrated pile drivers cannot change diameter. The construction method is based on a variable-diameter drilling and reaming integrated pile driver, which includes an active pipe, a driven pipe, an upper wing plate seat, a lower wing plate seat, and a reaming arm. The reaming arm is formed by connecting an upper wing plate and a lower wing plate. The upper wing plate is formed by connecting an upper wing plate and an upper wing plate link, and the lower wing plate is formed by connecting a lower wing plate and a lower wing plate link. The construction method determines the length of the reaming arm to be connected by adjusting the position of the upper wing plate seat on the gear key and the position of the lower wing plate seat on the driven pipe. Then, it adaptively adjusts the number of wing plate link connections. Through the coordinated cooperation between the components, it achieves reaming operations for different pile diameters, angles, and sizes, which is simple, convenient, and greatly improves construction efficiency.
