Manufacturing method for anti-seismic and anti-cracking concrete square pile
The invention discloses a manufacturing method for an anti-seismic and anti-cracking concrete square pile. The manufacturing method for the anti-seismic and anti-cracking concrete square pile is characterized by comprising the steps, carried out in sequence, of concrete mixing ratio designing, pouring, reinforcement inserting, tensioning, centrifugal shaping and high-pressure maintaining, the step of the tensioning uses multi-stage type gradient tensioning, and a step of natural maintaining is carried out before the step of the high-pressure maintaining. The manufacturing method for the anti-seismic and anti-cracking concrete square pile comprises the steps, carried out in sequence, of the concrete mixing ratio designing, the pouring, the reinforcement inserting, the tensioning, the centrifugal shaping and the high-pressure maintaining, the step of the tensioning uses the multi-stage type gradient tensioning, and the step of the natural maintaining is carried out before the step of the high-pressure maintaining; accordingly, the integral strength of the square pile is greatly improved, the connecting cost of pipe point components is lowered, and the penetrating power of the square pile is improved.
