Large-span steel truss girder floating towing erection construction method
The invention relates to the field of steel truss girder floating bracket erection construction and provides a large-span steel truss girder floating bracket erection construction method. The construction method comprises the following steps that a ground cage is arranged on the shore; a longitudinal pushing device is arranged on a pier top platform; a first winch, a second winch, a third winch, afourth winch and a fifth winch are arranged on a pontoon; the pontoon is pulled through the first winch and the second winch, and the longitudinal pushing device pushes synchronously; after moving inplace, the direction of a steel wire rope is changed, and the first winch and the second winch are dragged continuously; after longitudinally movement in place, a steel truss girder is driven to transversely move through the transverse pushing device and the third winch. Different winches are connected with the ground cage, existing obstacles such as piers can be effectively avoided, the influence on nearby buildings is reduced; meanwhile, in the transverse moving process of the steel truss girder, the trend of the steel wire rope can be changed through the second steering pulley block, the transverse moving process of the steel truss girder is completed; and the operation is convenient, and the construction efficiency is improved.
本发明涉及钢桁梁浮托架设施工领域，提供了一种大跨度钢桁梁浮拖架设施工方法。该施工方法包括以下步骤：在岸边设置地笼；在桥墩顶部平台上设置纵向顶推装置；在浮船上设置第一卷扬机、第二卷扬机、第三卷扬机、第四卷扬机和第五卷扬机；通过第一卷扬机和第二卷扬机牵拉浮船，纵向顶推装置同步顶推；移动到位后，更换钢丝绳走向，第一卷扬机和第二卷扬机继续拖拉；纵向移动到位后，通过横向顶推装置和第三卷扬机带动钢桁梁横移。本申请通过不同卷扬机与地笼连接，可有效避开既有桥墩等障碍物，减少了对附近建筑物的影响，同时，钢桁梁在横移过程中，可通过第二转向滑轮组改变钢丝绳的走向，完成钢桁梁的横移过程，操作便利，增加施工效率。
