Pushing installation method for large section of anchorage steel beam in upper-span sea
The invention provides a pushing installation method for a large section of an upper-span anchorage steel beam in the sea, which comprises the following steps: arranging temporary piers between permanent piers, and arranging pushing equipment on the pier tops of the permanent piers and the temporary piers; the first section and the front guide beam are hoisted to the top of pier top pushing equipment of the first permanent pier and the first temporary pier through a floating crane, the first section and the front guide beam are pushed to the position, located at the pier top of the first permanent pier, of the tail end of the first section through the pushing equipment, a rear guide beam is fixedly installed through a guide beam connector device, and a section steel box beam is obtained; pushing equipment is used for continuously pushing the whole section of steel box girder to the tops of pier top pushing equipment of the second permanent pier and the second temporary pier; by adopting the scheme that the floating crane is combined with the pushing device, and the rear guide beam is rapidly assembled and disassembled, the number of the arranged temporary piers can be greatly reduced, the construction amount of temporary supports is greatly reduced, the construction cost is reduced, the construction efficiency is improved, and the guide beam connector device can greatly improve the assembling and disassembling efficiency of the guide beam.
本发明提供一种上跨海中锚碇钢梁大节段顶推安装方法，在永久墩之间设置临时墩，在各个永久墩和临时墩的墩顶设置顶推设备；用浮吊将第一节段和前导梁吊装至第一永久墩和第一临时墩的墩顶顶推设备的顶部，使用顶推设备将第一节段和前导梁顶推至第一节段末端位于第一永久墩墩顶位置，通过导梁接头装置固定安装后导梁，得到节段钢箱梁；使用顶推设备继续顶推整个节段钢箱梁至第二永久墩和第二临时墩的墩顶顶推设备的顶部；通过采用浮吊与顶推组合，以及快速装拆后导梁的方案，能够大幅减少设置的临时墩数量，大幅减少了临时支撑的施工量，降低施工成本，提高施工效率，本发明的导梁接头装置能够大幅提高导梁的装拆效率。
