Corrosion-resistant steel pipe double-welded spiral bar UHPC-NC composite pile
A corrosion-resistant steel pipe double-welded spiral bar UHPC-NC composite pile relates to the field of civil engineering bridges and comprises a steel pipe and concrete poured in the steel pipe, the steel pipe is a corrosion-resistant steel pipe, and spiral bars are welded to the inner wall and the outer wall of the corrosion-resistant steel pipe respectively in the length direction of the corrosion-resistant steel pipe; the concrete is UHPC-NC concrete, and the UHPC-NC concrete is cast in situ in the inner cavity of the corrosion-resistant steel pipe welded with the spiral bar. The UHPC-NC concrete comprises UHPC concrete and NC concrete, the UHPC concrete is poured at the lower end of the interior of the corrosion-resistant steel pipe, and the NC concrete is poured at the upper end of the interior of the corrosion-resistant steel pipe. The concrete has good durability and corrosion resistance, can prevent the phenomena of debonding and void of the concrete and the corrosion-resistant steel pipe, is good in force transfer effect, can provide large enough bearing capacity, has the characteristics of good economic benefit, high toughness, strong adaptability and the like, and is particularly suitable for severe conditions and marine environments with strong corrosion.
一种耐蚀钢管双焊接螺旋筋UHPC‑NC复合桩，涉及土木工程桥梁领域，包括钢管、浇筑在钢管内的混凝土，所述的钢管为耐腐蚀钢管，该耐腐蚀钢管的内壁和外壁上均分别沿其长度方向焊接有螺旋筋；所述的混凝土为UHPC‑NC混凝土，该UHPC‑NC混凝土现浇在已焊接有螺旋筋的耐腐蚀钢管内部空腔中。所述的UHPC‑NC混凝土包括UHPC混凝土和NC混凝土，UHPC混凝土浇筑在耐腐蚀钢管内部下端，NC混凝土浇筑在耐腐蚀钢管内部上端。本发明具有良好的耐久性和抗腐蚀性能，可防止混凝土与耐腐蚀钢管出现脱粘脱空的现象，传力效果好，能够提供足够大的承载力，还具有经济效益好、韧性大、适应性强等特点，特别适用于恶劣条件和腐蚀性强的海洋环境。
