Continuous steel box girder skew bridge pushing process
The invention relates to a continuous steel box girder skew bridge pushing process which comprises the following steps: S1, respectively building pushing construction platforms on two sides of a bridge, the pushing construction platform comprises a front pushing bracket, a temporary pushing bracket and a rear pushing bracket which are arranged between two adjacent bridge piers, slideways which are respectively arranged on the front pushing bracket and the rear pushing bracket, and walking type pushing equipment which is arranged on the temporary pushing bracket; and S2, a front guide beam and a plurality of steel box beams are sequentially hoisted to the pushing construction platform and assembled into bridge segments, then the current assembled bridge segment is pushed through the walking type pushing equipment, and assembling of the next bridge segment is repeated. By reasonably designing the multi-round pushing length and assisting with corresponding hoisting control and pushing bracket arrangement, the method is suitable for variable-height bridge pushing or bridge pushing with multiple sections of curves.
本发明涉及一种连续钢箱梁斜交桥顶推工艺，其包括以下步骤，S1对桥梁两侧分别搭建顶推施工平台，所述顶推施工平台包括布置于相邻两个桥墩之间的前顶推支架、顶推临时支架和后顶推支架、分别设置于所述前顶推支架和后顶推支架上的滑道、以及设置于顶推临时支架上的步履式顶推设备；S2先将前导梁和多个钢箱梁依次吊装至所述顶推施工平台上，并拼装为桥梁片段，再利用所述步履式顶推设备顶推处拼装好的当前桥梁片段，并重复进行下一桥梁片段的拼装。本发明通过合理设计多轮次顶推长度并辅以相应的吊装控制及顶推支架布置，适用于变高度或设置多段曲线的桥梁顶推。
