[0002] In the field of ground pile foundation construction, it is necessary to set up a pile foundation on the ground. First, a pile foundation hole is excavated on the ground, and then a steel cage is lowered into the pile foundation hole, and then concrete is poured. When the steel cage is lowered into the pile foundation hole, in order to prevent the steel cage from colliding with the inner wall of the pile foundation hole and causing the inside of the pile foundation hole to collapse, a guide cylinder is required to be arranged on the upper side of the pile foundation hole so that the steel cage can move downward along the guide cylinder to achieve the purpose of guidance. Because the ground around the pile foundation hole has poor hardness due to excavation, after the guide cylinder is placed around the pile foundation hole, it is easy to tilt due to the influence of the ground drop and the small contact range between the guide cylinder and the ground, which affects the smooth lowering of the steel cage. Therefore, it is necessary to design a pile foundation guide device that increases or decreases the contact range between the guide structure and the ground according to the on-site ground conditions.
