Production technology of precast reinforced concrete piles
The invention discloses a production technology of precast reinforced concrete piles. The technology comprises the following steps: making a steel reinforcement cage, putting the steel reinforcement cage in a precast concrete pile die, injecting concrete to the die, arranging the die in a centrifuge device, carrying out centrifugal rotation, carrying out steam curing in a curing pool, demolding, taking out, and molding. The precast concrete pile die is an elongated die with the length of above 25m, and a plurality of precast concrete piles can be simultaneously produced through one die; and the above concrete is prepared from the following raw materials, by weight, 80-100 parts of a gelling material, 20-30 parts of fine aggregate, 30-100 parts of coarse aggregate, 5-10 parts of a water reducer and 100-200 parts of water. The elongated steel die adopted in the invention allows a plurality of centrifugal concrete piles with the length of above 10m to be made, the concrete formula is reasonable, and the centrifugal concentrate piles made in the invention have high strength and good quality.
