Method and system for installing large steel bridge
The invention provides a method and a system for installing a large steel bridge, and is used for installing the large steel bridge on piers through a transport ship, the piers are provided with three-dimensional jacks, and the method comprises the steps that the whole assembled large steel bridge slides to the transport ship through a sliding supporting frame, and the large steel bridge is bound on the sliding supporting frame; the sliding support frame can bear self weight during shipment and load caused by marine acceleration during transportation; after the transport ship reaches a specified mounting position, anchoring and positioning, and ballasting by using a ballasting system so that the bridge bottom surface of the large steel bridge is in contact with the three-dimensional jacks on the bridge piers; the large steel bridge is supported by the three-dimensional jacks; and after the height of the transport ship between the bridge bottom surface of the large steel bridge and the sliding supporting frame reaches the safe height, the transport ship is moved out of the designated installation position, and installation is completed. According to the embodiment of the invention, the general assembly of the large steel bridge is completed before installation, and the jack is used for installation so that the construction difficulty is reduced.
本发明提供一种大型钢桥安装的方法和系统，用于通过运输船将所述大型钢桥安装在桥墩上，桥墩上设有三维千斤顶，方法包括：将总拼完成的大型钢桥整体通过滑移支撑架滑移到运输船上，并将所述大型钢桥绑扎在滑移支撑架上，滑移支撑架能够承受装船时的自重和运输时海运加速度引起的载荷；运输船在到达指定安装位置后通过抛锚定位，使用压载系统进行压载，使所述大型钢桥的桥底面与所述桥墩上的所述三维千斤顶接触；三维千斤顶将大型钢桥托起；所述运输船在大型钢桥的桥底面与滑移支撑架间的高度达到安全高度后移出所述指定安装位置，完成安装。本发明实施例在安装前将大型钢桥总装完成，同时使用千斤顶进行安装，减少了施工难度。
