Large-diameter overlength overweight circular steel casing duplex air bag launching construction method
The invention discloses a duplex air bag launching construction method for a large-diameter super-long overweight circular steel casing. The method comprises the steps that a concrete ground anchor is arranged, and a winch is installed; a plurality of side-by-side jig frames are placed to temporarily place the steel casings, the steel casings on the two sides are lengthened to the required length, steel plates are connected with opening bolts at the two ends, water stop rubber strips and I-shaped steel are cushioned to transversely and temporarily weld the steel casings into a whole, and synchronous launching is guaranteed; an air bag is arranged between the jig frames on the two sides below the steel casing, the steel casing is connected with the pulley block through a steel wire rope and an unhook and then penetrates through the ground anchor to be connected with the winch, at the moment, the steel casing, the ground anchor and the winch form a right angle with the ground anchor as the vertex, and the air bag is slowly and synchronously inflated by several times; after the steel casing is jacked by the air bag, the jig frame is pulled out, the steel casing is lowered to a designated position by controlling the speed through the winch, and the steel casing is quickly flushed into water by opening the unhook and floats by means of the buoyancy of the steel casing; the structure is simple, the construction process is easy to implement, operation is convenient, safety and economy are achieved, and construction efficiency is high.
本发明公开了一种大直径超长超重圆形钢护筒双联气囊下水施工方法，包括：设置砼地锚，安装卷扬机；放置若干个并排胎架临时安放钢护筒，分别接长两侧钢护筒至需求长度，通过钢板与两端开口螺栓连接并垫止水胶条，工字钢将钢护筒横向临时焊接成一个整体，确保同步下水；在钢护筒下方两侧胎架间布置气囊，在使用钢丝绳和脱钩将钢护筒与滑轮组连接后，再穿过地锚与卷扬机相连，此时钢护筒、地锚、卷扬机以地锚为顶点呈直角，对气囊缓慢分次同步充气；在钢护筒被气囊顶升后抽出胎架，通过卷扬机控制速度将钢护筒下放至指定位置，打开脱钩使钢护筒快速冲入水中，并依靠自身浮力漂浮；本发明结构简单、施工工艺易行、操作方便、安全经济、施工效率高。
