Accurate positioning sinking method for large-diameter steel open caisson
The invention provides an accurate positioning sinking method for a large-diameter steel open caisson. The accurate positioning sinking method comprises the following main construction steps of a combined anchor is constructed, a steel open caisson is launched, tugs are put in place to be connected with the steel open caisson, the steel open caisson is dragged to the downstream of a pier position, an anchor is anchored, upper and lower pulling cables of an anchorage pier are connected with the steel open caisson, the steel open caisson slowly gets close to a abutting pier and is moored, the abutting pier and upper and lower pulling cables of a side anchor platform are connected, the steel open caisson is primarily positioned, the steel open caisson sinks to a positioning state through water injection, the steel open caisson is accurately positioned and timing is determined to inject. According to the method, the steel open caisson is positioned in the mode that the anchorage piers, the abutting piers and concrete anchorage are combined, the open caisson abuts against the abutting piers mainly through the pulling cables and the tugs, then the position of the open caisson is adjusted through the arranged pulling cables, water flow force and wind load are borne, and the problem of positioning sinking caused by the impact of strong wind and torrent in the positioning sinking process of a large-diameter steel open caisson is effectively solved.
本发明创造提供了一种大直径钢沉井精确定位沉放方法，主要施工步骤为：组合锚施工、钢沉井下水、拖轮就位与钢沉井连接、拖拉钢沉井至墩位处下游、锚碇、锚墩上下拉缆与钢沉井连接→钢沉井缓慢靠近靠墩并停泊→连接靠墩及边锚平台上下拉缆→钢沉井初定位→钢沉井注水下沉至定位状态→钢沉井精定位→确定时机注水着床。本发明采用锚墩、靠墩、混凝土锚碇组合形式，对钢沉井进行定位，主要通过拉缆及拖轮将沉井顶靠于靠墩上，然后利用设置的拉缆调整沉井位置，并承担水流力及风力荷载，有效解决大直径钢沉井在定位沉放中受大风、急流的冲击而引起的定位沉放的难题。
