Segmental beam retreating type construction method
The invention relates to a segmental beam construction method, in particular to a segmental beam retreating type construction method which comprises the following steps: S1, expanding foundation construction; s2, a temporary steel pipe support is erected and used for standing of a second leg, a third leg and a fourth leg of bridge crane equipment; s3, assembling and debugging the bridge girder erection machine; s4, the bridge girder erection machine passes through the hole in a retreating mode; and S5, erecting the segmental beam. According to the segmental beam retreating type construction method, a bridge girder erection machine is assembled and debugged in the large-mileage erection direction, a 24-31 # beam span is erected firstly, the trestle renting fee can be saved, then after the bridge girder is returned to a transition site, retreating type segmental beam erection is conducted under the condition that the bridge girder is not turned around for secondary assembly, the secondary turning-around assembly and debugging time of the bridge girder is saved, and the construction efficiency is improved. The erection cost is saved, and the erection period is advanced.
本发明涉及一种节段梁施工方法，尤其是一种节段梁后退式施工方法，包括以下步骤：S1、扩大基础施工；S2、临时钢管支架搭设，用于桥机设备2号、3号腿、4号腿的站位；S3、架桥机拼装和调试；S4、架桥机后退式过孔；S5、节段梁架设。一种节段梁后退式施工方法使架桥机沿大里程架设方向拼装、调试，先行架设24～31#梁跨，可节约栈桥租赁费，然后桥机退回至转场后起架点在桥机不调头二次拼装的情况下进行后退式节段梁架设，节约桥机二次掉头拼装、调试时间，节省了架设成本，提前了架设工期。
