Method and device for forming oblique and vertical rotary tube pile

The invention relates to a method and a device for forming an oblique and vertical rotary tube pile. The method comprises the following steps:(1) preparing raw material, (2) loading a steel reinforcement cage into a steel die and applying pre-stressing force, (3) hoisting the steel die onto a platform and tilting the platform, (4) driving the steel die to rotate by a power unit, abutting a telescopic feed pipe of a feeding device and a charging hole of an anchoring plate and charging the material, and (5) installing the steel die on a centrifuger for centrifugal forming. The device comprises the platform, a supporting frame of the platform, a hydraulic cylinder and a feeding device, wherein the feeding device is positioned at the upper right or the upper left of the platform. Compared with the traditional technology, the degree of automation of feeding processes is greatly improved, the labor intensity is greatly relieved, the number of feeding persons is decreased by 50- 80 percent, the process time is short
