Installation and construction method for steel box girder crossing existing bridge
The invention discloses a construction method for mounting a steel box girder across an existing bridge, which comprises the following steps of: placing first hoisting equipment and second hoisting equipment as well as a first steel box girder and a second steel box girder on the same side of the existing bridge, hoisting the first steel box girder and the second steel box girder to the existing bridge in sequence through the first hoisting equipment and the second hoisting equipment, and hoisting the first steel box girder and the second steel box girder to the existing bridge; then the first steel box girder is hoisted to the steel box girder mounting position through first hoisting equipment, then the second steel box girder is moved out from the lower portion of the first steel box girder and then hoisted to the steel box girder mounting position, and therefore interference between the first steel box girder and the second steel box girder and a building on the side edge of an existing bridge during hoisting can be avoided; and interference between the second steel box girder and the first steel box girder and between the second steel box girder and the piers on the two sides during hoisting can be avoided. Therefore, the construction method can be suitable for the situation that other buildings exist on the two sides of the existing bridge and other construction sites are narrow.
本发明公开了一种钢箱梁跨既有桥梁安装施工方法，包括以下步骤：将第一起重设备、第二起重设备与第一钢箱梁、第二钢箱梁置于既有桥梁的同一侧，先通过第一起重设备、第二起重设备依次将第一钢箱梁、第二钢箱梁抬吊至既有桥梁上，而后通过第一起重设备先将第一钢箱梁吊装至钢箱梁安装位，再将第二钢箱梁从第一钢箱梁的下方移出再吊装至钢箱梁安装位，由此能够避免第一钢箱梁和第二钢箱梁在吊装时与既有桥梁侧边的建筑物之间出现干涉，并且能够避免第二钢箱梁在吊装时与第一钢箱梁以及两侧的桥墩之间出现干涉。由此可见，该种施工方法能够适用于既有桥梁两侧存在其他建筑物等施工场地狭小的情况。
