Incremental launching construction method for steel box girder crossing embankment hole
The invention relates to an embankment-hole-crossing steel box girder incremental launching construction method. The method comprises the following steps that steel box girder sections are lifted to an incremental launching platform through a lifting system; butting the steel box girder section and the steel guide girder, integrally pushing the steel box girder section and the steel guide girder to one side of the land by utilizing pushing equipment, and welding a new steel box girder section after the girder is erected; and repeating the step 3 to the step 4 until the steel box girder crosses the last group of pushing brackets. The method has the beneficial effects that the steel box girder segments manufactured in a processing plant in a segmented mode are transported to the bridge site through the transport ship, the steel box girder is pushed from the water adjacent side to the land side, the problem that transportation is inconvenient due to the special terrain of a bridge crossing the embankment hole can be effectively solved, and the pushing construction efficiency of the embankment-crossing steel box girder is effectively improved.
本发明涉及一种跨堤孔钢箱梁顶推施工方法，包括以下步骤：利用提升系统将钢箱梁节段拎吊至顶推平台；将钢箱梁节段和钢导梁进行对接，利用顶推设备将钢箱梁节段和钢导梁整体向陆地一侧顶推，并在已架梁后焊接新的钢箱梁节段；重复步骤三至步骤四直至钢箱梁跨越最后一组顶推支架。本发明的有益效果是：利用运输船将在加工厂幅分段制作完成的钢箱梁节段运输至桥位处，将钢箱梁从邻水侧向陆地侧进行顶推，可有效克服跨堤孔桥梁的特殊地形导致的运输不便的难题，有效提高跨堤钢箱梁顶推施工效率。
