| 摘 要： | 济南小清河项目难点施工为架设3片钢箱梁(垂直于桥向),每片由5节(沿桥向)钢箱梁组成,共约600吨。采用先轮箱纵移到钢箱梁对应的跨位,再利用自锁爬行顶推小车横移至梁位处,落梁就位(中间9节钢箱梁)。两头的钢箱梁利用大吨位吊车和已经就位好的钢箱梁对接架设。很好地解决了单片整体吊装钢箱梁接头变形影响问题。

| Abstract: | Jinan Xiaoqing difficult construction project is the erection of three steel box girders (perpendicular to the bridge to),each piece is composed of 5(along the bridge to)steel box girders,about 600 tons. A first-round steel box girder box is moved to the corresponding vertical cross-bit,and re-use of self-locking crawling pushing trolleys to move cross-beam is located off the beam in place (nine steel box girders are in the middle). The use of two steel box girder in place large-tonnage cranes and box girde... |
