Construction method of road reconstruction and extension bridge splicing system
The invention relates to a construction method of a road reconstruction and extension bridge splicing system. The scheme comprises the following steps: (1) construction preparation; (2) pier column and capping beam construction; (3) the original bridge T beam is jacked, and a support is replaced; (4) drilling and steel bar planting are conducted on the original bridge T-beam; (5) mounting a T-beam web tensioning and diagonal bracing system; (6) cutting and chiseling away original bridge deck plate pavement concrete; (7) hoisting the diaphragm plate integral reinforcement cage; (8) mounting a diaphragm plate template system; (9) integrally pouring the diaphragm plate and the wet joint; and (10) shrinkage concrete is poured and supplemented. According to the method, the lifting stability of the original bridge is guaranteed, the connectivity between the original bridge and the broadened bridge is enhanced, the pouring quality of the diaphragm plate is good, a wet joint surface layer is free of a cracking phenomenon, and good technical and economic benefits are obtained.
本申请涉及公路改扩建桥梁拼接体系施工方法，该方案包括(1)施工准备；(2)墩柱、盖梁施工；(3)原桥T梁顶升更换支座；(4)原桥T梁钻孔植筋；(5)T梁腹板张拉对撑体系安装；(6)切割凿除原桥面板铺装砼；(7)吊装横隔板整体式钢筋笼；(8)安装横隔板模板体系；(9)横隔板与湿接缝一体化浇筑；(10)浇筑补充收缩性混凝土。本申请保证了原桥抬升的稳定性，增强了原桥与拓宽桥之间的联结性，横隔板浇筑质量好，湿接缝面层无开裂现象，取得了较好的技术、经济效益。
