Steel box girder temporary pier construction method
The invention provides a steel box girder temporary pier construction method which comprises the following steps: during construction, firstly completing construction of a lower-layer steel pipe pile, then inserting a prefabricated upper-layer steel pipe pile into the lower-layer steel pipe pile to form a temporary pier, and then supporting a steel box girder on a bearing beam at the top of the upper-layer steel pipe pile; at the moment, most of the upper-layer steel pipe piles are located in the lower-layer steel pipe piles, and at the moment, the steel box girder is in a low-position girder storage state, so that the technical scheme has flexibility and timeliness, temporary piers can have the capacity of resisting longitudinal bridge wind loads without being reinforced through low-position girder storage, materials for the temporary piers are greatly saved, the construction cost is reduced, and the construction period is shortened. And the steel box girder can be lifted at any time according to the construction progress for welding construction, and the height of the temporary pier can be adjusted according to the actually required girder storage height.
本发明提供了一种钢箱梁临时墩施工方法，在施工时，先完成下层钢管桩的施工，再将预制好的上层钢管桩插入下层钢管桩内，形成临时墩，然后再将钢箱梁托放于上层钢管桩顶部的承重梁上，由于此时上层钢管桩大部分均位于下层钢管桩内，此时钢箱梁处于低位存梁状态，本发明技术方案具有灵活性和时效性，其可通过低位存梁使临时墩无需加固即可具有抵抗纵桥向风荷载的能力，大大节省了临时墩用料，降低了施工成本，又可根据施工进度随时提吊钢箱梁进行焊接施工，还可根据实际需求的存梁高度来调整临时墩的高度。
