Hoisting method for hoisting steel truss bridge by using double floating cranes
The invention discloses a hoisting method for hoisting a steel truss bridge by double floating cranes. The hoisting method comprises the following steps: step 1, firstly, determining the positions of two groups of hoisting points of the steel truss bridge; 2, according to the overall weight of the steel truss bridge, two floating cranes meeting the load requirement are selected; 3, pre-perforating is conducted on the steel truss bridge on site, and the periphery of a prefabricated hole is sleeved with a rubber ring; 4, a steel wire rope penetrates through the prefabricated holes and is fixed to the hooks of the two floating cranes; 5, the two ends of the two steel wire ropes are connected to the two sets of corresponding lifting points on the steel truss bridge correspondingly; and 6, finally, hoisting of the steel truss bridge is completed by controlling the two floating cranes. The two floating cranes are connected with the two groups of steel wire ropes through the steel cross beams, and the steel wire ropes sequentially penetrate through the upper chord member, the web member and the lower chord member of the steel truss bridge, so that the steel truss bridge and the hoisting equipment form a whole, the steel truss bridge is not prone to excessively rotating in the floating hoisting process, and the safety and stability of the floating hoisting process are improved.
本发明公开了一种浮吊船双船抬吊钢桁架桥的吊装方法，包括如下步骤：步骤1：首先确定钢桁架桥的两组吊点的位置；步骤2：根据钢桁架桥的整体重量，选择两艘满足荷载要求的浮吊船；步骤3：现场在钢桁架桥上进行预穿孔，并在预制孔洞周围套上橡胶圈；步骤4：然后将钢丝绳穿过预制孔洞并固定在两艘浮吊船的挂钩上；步骤5：接着将两根钢丝绳的两端分别连接在钢桁架桥上对应的两组吊点上；步骤6：最后通过操控两艘浮吊船完成对钢桁架桥的吊装；两艘浮吊船通过钢横梁连接两组钢丝绳，钢丝绳依次穿过钢桁架桥的上弦杆，腹杆以及下弦杆，使得钢桁架桥与吊装设备成为一个整体，使钢桁架桥在浮吊过程中不易发生过大转动，提高了浮吊过程的安全与稳定。
