摘要
本文针对西北地区的低温气候条件,研究了胶材种类及用量、水胶比、管桩蒸养制度、聚羧酸减水剂种类等对免蒸压PHC管桩混凝土的强度性能影响因素。研究结果表明采用单免工艺生产PHC管桩在技术、工艺、成本及地区环境等方面可行,并实现单免PHC管桩在西北地区工业化生产中的应用。
The studies the influence factors on the strength performance of Non-autoclaved PHC pipe pile concrete, such as the types and dosage of glue materials, water-binder ratio, pipe pile steam curing system, types of polycarboxylate superplasticizer, in view of the low temperature climate conditions in northwest China. The research results show that it is feasible to produce PHC pipe piles with single exemption process in terms of technology, process, cost and regional environment, and realize the application of single exemption PHC pipe piles industrial production in northwest China.
