The invention discloses a 3D printing self-locking assembly construction method of a large-span special-shaped arch structure. The 3D printing self-locking assembly construction method comprises the following steps that (1) the large-span special-shaped arch structure is divided into a plurality of sub arch rings which are sequentially connected from one end to the other end, and any two adjacentsub arch rings can be self-locked; (2) the printing contour design of each sub arch ring is completed, data readable by a concrete 3D printer are output, and the data are imported into the printer; (3) an outer shell template of each sub arch ring and the back cover of each outer shell template are subjected to 3D printing, and watering maintenance is carried out for 28 days; (4) steel reinforcement cages are manufactured, the steel reinforcement cages are arranged in the corresponding outer shell templates, then concrete is poured in the outer shell templates, and vibrating is carried out; and (5) all the sub arch rings are transported to a construction site, and the sub arch rings are sequentially hoisted from the position close to the bridge abutment to the position away from the bridgeabutment till full arch assembly is completed. According to the 3D printing self-locking assembly construction method of the large-span special-shaped arch structure, the construction difficulty of 3D printing of the large-span special-shaped arch structure is effectively reduced, and the construction efficiency of the large-span special-shaped arch structure is improved.
本发明公开了一种大跨度异型拱结构的3D打印自锁装配建造方法，包括以下步骤：(1)将大跨度异型拱结构由一端至另一端分为若干个依次相连的子拱圈，且任意相邻的两个子拱圈能够自锁；(2)完成每个子拱圈的打印轮廓设计，并输出为混凝土3D打印机可读取的数据，导入打印机。(3)3D打印每个子拱圈的外壳模板，以及外壳模板的封底，并洒水养护28天；(4)制作钢筋笼，并将钢筋笼设置在对应的外壳模板内，然后在外壳模板内浇筑混凝土，振捣；(5)将各个子拱圈运至施工现场，按照从接近桥台至远离桥台的顺序依次吊装子拱圈，直至全拱装配完成。本发明有效降低了大跨度异型拱结构3D打印的建造难度，提高了大跨度异型拱结构的建造效率。
