Precise and rapid anti-collision hoisting method for ramp steel box girder connected into existing viaduct
The invention discloses an accurate and rapid anti-collision hoisting method for a ramp steel box girder connected into an existing elevated road. The method comprises the following steps: carrying out lengthening and support changing treatment on an existing cross beam of the highway; all supporting frame bodies are built between every two adjacent lengthened cross beams, and transportation rails are laid on the supporting frame bodies; each transportation platform truck is hoisted to the corresponding first section of transportation track, and then each section of steel box girder is hoisted and placed on the transportation platform truck in sequence; all the sections of steel box girders are sequentially conveyed to the construction position along the conveying rail; the two adjacent steel box girders are welded; the whole section is driven to descend until the two ends of the section abut against the adjacent lengthened cross beams respectively; each transportation platform truck is transported to the main track between the next two adjacent lengthened cross beams; and the anti-collision wall is dismantled, and the anti-collision wall is built on the side edge of the ramp. The highway construction method has the effect of improving the overall construction progress under the condition that damage to an original highway is reduced.
本发明公开了一种接入既有高架的匝道钢箱梁精准快速防撞吊装方法,其包括对高速路既有横梁加长换撑处理；在相邻两根加长横梁之间位置搭建所有支撑架体，在支撑架体上铺设运输轨道；将各辆运输平台车吊装至对应第一节的运输轨道上，再依次吊装各节钢箱梁放置于运输平台车上；将各节钢箱梁依次沿运输轨道输送至施工位置；将相邻两钢箱梁之间进行焊接；驱使整段下放直至使得该段两端分别抵压在相邻的加长横梁上；将各个运输平台车运输至下一相邻两根加长横梁之间的主轨道上；拆除防撞墙，在匝道侧边建设防撞墙。本申请具有在减少出现对原有高速路造成损坏的情况下，提升整体的施工进度的效果。
