Prefabricated UHPC-stainless steel sleeve confined seawater and sea sand concrete composite column and construction method
The invention relates to a prefabricated UHPC-stainless steel sleeve confined seawater and sea sand concrete composite column and a construction method.The prefabricated UHPC-stainless steel sleeve confined seawater and sea sand concrete composite column comprises a seawater and sea sand concrete core column and a prefabricated UHPC-stainless steel sleeve wrapping the seawater and sea sand concrete core column, and the prefabricated UHPC-stainless steel sleeve comprises a stainless steel pipe and a UHPC outer wrapping layer which are arranged from inside to outside; and an interface connecting structure is fixed on the outer surface of the stainless steel pipe so as to enhance the bonding performance between the UHPC outer cladding and the stainless steel pipe. According to the prefabricated UHPC-stainless steel sleeve restrained seawater and sea sand concrete combination column, the stainless steel pipe serves as an inner mold, the stainless steel pipe and the inner mold are manufactured together in a factory to form the hollow prefabricated UHPC-stainless steel sleeve, offshore hoisting is facilitated, the prefabricated UHPC-stainless steel sleeve can serve as a construction formwork of a seawater and sea sand concrete core column after being transported to the site, the construction process is simplified, construction cost is saved, and the construction efficiency is improved. The concrete has the advantages of being good in erosion corrosion resistance, high in bearing capacity, high in anti-seismic property, short in construction period, low in whole life cycle cost and the like.
本发明涉及一种预制UHPC‑不锈钢套管约束海水海砂混凝土组合柱及施工方法，包括海水海砂混凝土芯柱及包裹于海水海砂混凝土芯柱外部的预制UHPC‑不锈钢套管，所述预制UHPC‑不锈钢套管包括由内至外设置的不锈钢管及UHPC外包层，所述不锈钢管外表面固定有界面连接构造以增强UHPC外包层与不锈钢管间的粘结性能。本发明预制UHPC‑不锈钢套管约束海水海砂混凝土组合柱的UHPC外包层以不锈钢管为内模并在工厂一起制作形成空心的预制UHPC‑不锈钢套管，便于海上吊装，在运至现场后可作为海水海砂混凝土芯柱的施工模板，简化施工过程，节约建设成，具有耐冲蚀腐蚀性能好、承载能力高、抗震性能强、施工周期短、全生命周期成本低等特点。
