Abstract
The invention relates to a method for producing precast concrete piles, which comprises the following main steps of: manufacturing a reinforcement cage; placing the reinforcement cage into a die; pouring concrete into the die; centrifugally rotating; and carrying out steam curing. The method is characterized in that the die with the length of over 20 meters is adopted in the method; two or a plurality of precast concrete piles can be simultaneously produced by one die; upper and lower half dies of the die have a transporting mode of transversely moving in parallel in the direction vertical to the axis of a crane beam of a plant in the production process; and centrifugal equipment and a curing tank are transversely arranged in parallel in the direction vertical to the axis of the crane beam of the plant. Due to the adoption of the transverse flow production scheme of the long die, the production effect can be multiplied, the space occupied by the plant is greatly reduced, a great amount of lands are saved, the working efficiency is improved, and the production quality can be ensured.
