The invention provides a preparation method of a non-autoclaved high-performance prefabricated pipe pile. The method adopts the following steps including taking special cement for the pipe pile, an S115-grade composite admixture, a high-performance water reducing agent, machine-made sand and gravel as raw materials, preparing concrete, uniformly stirring, preparing a reinforcement cage, distributing and tensioning, centrifugally forming, carrying out normal-pressure steam curing, demolding, carrying out quality inspection, putting into a product storage yard and the like to obtain the finished non-autoclaved high-performance prefabricated pipe pile. The method is simple in process and low in cost, the prepared finished non-autoclaved high-performance prefabricated pipe pile has good stability, hitting (pressing) resistance, permeability resistance and corrosion resistance, the product design life is prolonged, durability is remarkably improved, conversion from common high-strength concrete to high-performance concrete of the pipe pile is achieved, and the concepts of ecological priority, green development and high-quality development in the new era are realized.
本发明提供了一种免蒸压高性能预制管桩的制备方法，该方法以管桩专用水泥、S115级复合掺合料、高性能减水剂、机制砂和碎石作为原料，经混凝土配料、搅拌均匀、制备钢筋龙、布料张拉、离心成型、常压蒸汽养护、脱模、质检入产品堆场等步骤，得到成品免蒸压高性能预制管桩。本发明所述方法工艺简单，成本低，制备出的成品免蒸压高性能预制管桩具有良好的稳定性，耐打(压)性，和良好的抗渗性、耐腐蚀性，产品设计寿命延长，耐久性显著提升，实现了管桩普通高强砼向高性能混凝土的转变，符合新时代下生态优先，绿色发展以及高质量发展的理念。
