Ultra-high performance geopolymer concrete permanent formwork filled with SFCB concrete prefabricated pipe pile and preparation method of ultra-high performance geopolymer concrete permanent formwork filled with SFCB concrete prefabricated pipe pile
The invention provides a prefabricated pipe pile with an ultrahigh-performance geopolymer concrete permanent formwork filled with SFCB concrete and a preparation method of the prefabricated pipe pile. The pipe pile is characterized in that the ultrahigh-performance geopolymer concrete permanent formwork serves as an outer pipe; the ultrahigh-performance geopolymer concrete permanent formwork serves as an inner pipe, and the outer pipe is arranged outside the inner pipe in a sleeving mode. The composite material grids are respectively arranged in the middle positions of the outer pipe and the inner pipe; the common concrete is poured between the outer pipe and the inner pipe; the SFCB straight bars are arranged in the common concrete; and the FRP spiral stirrups surround the outer sides of the SFCB straight ribs. The pipe pile is good in durability and anti-seismic toughness and has the advantages of being environmentally friendly and low in cost.
本发明提供一种超高性能地聚物混凝土永久模壳内填SFCB混凝土预制管桩及其制备方法，管桩包括：超高性能地聚物混凝土永久模壳作为外管；超高性能地聚物混凝土永久模壳作为内管，外管套设在内管的外部；复合材料网格，分别配置在外管和内管的中间位置；普通混凝土，浇筑在外管和内管之间；SFCB直筋，布设在普通混凝土中；及FRP螺旋箍筋，环绕在SFCB直筋的外侧。本发明的管桩耐久性和抗震韧性好，并兼具环保和低成本的优点。
