Steel casing duplex air bag launching construction method
The invention discloses a steel casing duplex air bag launching construction method, and relates to the technical field of launching of large-diameter overlength overweight circular steel casings into water, and the method comprises the following steps: S1, preparation work of the steel casings: S1-1, leveling of a launching ramp, S1-2, positioning of a casing extension jig frame, S1-3, plugging of two ends of a casing, and S1-4, connection welding of casings; and S2, installation of a pile casing drainage system, wherein the step S2 comprises the substeps of (S2-1) winch installation, (S2-2) ground anchor machining and installation, and (S2-3) pulley block and steel wire rope installation. The jig frame 21 and the air bag are arranged through the pile casing assembly, the mode that the air bag assists in launching is adopted, the air bag can be recycled, large hoisting equipment is not needed, economical efficiency is good, hoisting falling accidents are avoided, and operation safety and construction flexibility are improved; the two independent steel casing bodies can form a duplex system, and the two large-diameter super-long and super-heavy steel casing bodies are connected together through the connection between the casing bodies.
本发明公开了一种钢护筒双联气囊下水施工方法，涉及大直径超长超重圆形钢护筒下放入水技术领域，包括S1、钢护筒的准备工作，其包括S1‑1下水坡道平整、S1‑2护筒接长胎架定位、S1‑3护筒两端封堵、S1‑4护筒间联系焊接；S2、护筒下水系统安装，其包括S2‑1卷扬机安装、S2‑2地锚加工安装、S2‑3滑轮组，钢丝绳安装。本发明通过护筒组件设置胎架21和气囊，采用气囊辅助下水的方式，气囊可循环利用，且无需大型吊装设备，经济性好，不会发生吊装坠落事故，提升作业的安全性和施工灵活性，通过设置封堵板、工字钢和槽钢，可以使两个独立的钢护筒体形成双联体系，将两根大直径超长超重钢护筒通过护筒间联系连接在一起。
