Efficient piling system for building

The invention belongs to the technical field of piling, and particularly relates to an efficient piling system of a building. A flexible friction rack is fixedly arranged on the end face of the side, close to the center, of a pushing sliding block, and the friction rack is arranged in the friction rack to move in cooperation with a foam plate, so that double fixation of a pile body is achieved; according to the invention, the front and back symmetrical power motors are fixedly arranged in the supporting rack, the front and back symmetrical power shafts are rotatably arranged on the front end face of the supporting rack, the front and back symmetrical power shafts are arranged on the front end face of the supporting rack, and the pile bodies with different sizes and different shapes can be accurately fixed, so that the traditional limitation is further changed, and the stability and the safety of the pile bodies during working are further ensured. And a power connecting rod is fixedly arranged on the outer cir
