This invention discloses a high-friction, low-thermal-conductivity prestressed concrete pipe pile processing device, belonging to the field of concrete pipe pile processing technology. The device includes a mold, a drive unit, and a connecting shaft. It also includes a mixing mechanism comprising a mixing paddle and a telescopic mechanism. The telescopic mechanism drives the mixing paddle to move radially along the mold, and the mixing paddle mixes the concrete raw materials inside the reinforcing cage. A moisture content meter detects the real-time moisture content of the concrete raw materials. When the real-time moisture content is less than a threshold value, the controller controls the telescopic mechanism to contract, so that the distance from the sidewall of the mixing paddle to the axis of the connecting shaft is equal to the designed inner diameter of the pre-processed pipe pile, and the length direction of the mixing paddle is parallel to the axial direction of the mold. This high-friction, low-thermal-conductivity prestressed concrete pipe pile processing device can suppress the segregation of fly ash hollow microspheres, avoid powder shedding from the inner wall, and increase the friction of the processed pipe pile.
