Construction method of asymmetric steel beam double-cantilever bridge and bridge
The invention relates to a construction method of an asymmetric steel beam double-cantilever bridge. The construction method comprises the following steps that a plurality of preset pier areas are arranged between two bridge abutments; a pier is poured in the preset pier area; temporary supporting frames are erected on the two sides of the constructed bridge pier; supporting point steel beams are erected on the two sides of each constructed pier, and the supporting point steel beams are connected with the temporary supporting frames; connecting steel beams are erected on the two sides of the fulcrum steel beam and connected with the temporary supporting frame, the connecting steel beams are provided with heavy steel beams and light steel beams, ballasting objects are arranged on the light steel beams, and the weights of the heavy steel beams are balanced through the ballasting objects; connection of the connecting steel beams between the adjacent bridge piers is completed; connection of the connecting steel beams between the bridge pier and the bridge abutment is completed. The method has the beneficial effects that the ballasting objects are arranged on the light steel beams, the weight of the heavy steel beams is balanced by the ballasting objects, supporting can be achieved only through the temporary supporting frames below the connecting steel beams, and meanwhile erecting of the temporary supporting frames is reduced.
本发明涉及一种不对称钢梁双悬臂桥梁的施工方法，包括以下步骤：在两桥台之间设置若干预设桥墩区域；在预设桥墩区域浇筑桥墩；在施工完成的桥墩两侧架设临时支撑架；在各个施工完成的桥墩两侧架设支点钢梁，且将支点钢梁与临时支撑架连接；在支点钢梁两侧架设连接钢梁，且将连接钢梁与临时支撑架连接，其中，连接钢梁设有重钢梁和轻钢梁，在轻钢梁上配置压重物，利用压重物平衡重钢梁的重量；完成相邻的桥墩之间连接钢梁的连接；完成桥墩与桥台之间连接钢梁的连接。本发明的有益效果在于：通过在轻钢梁上配置压重物，利用压重物平衡重钢梁的重量，使连接钢梁下方只需临时支撑架便能实现支撑，同时，减少了临时支撑架的架设。
