摘要
九龙岗特大桥188#和189#墩紧靠既有的淮南铁路,为了确保淮南铁路的行车和施工安全,在低桩承台施工时,采用D型施工便梁对线路进行加固;用型钢"钢板桩围堰"加固低桩承台基坑,确保了既有铁路线路的行车安全和桥涵施工安全。实施方案可供同类工程参考。
Owing to the fact that piers 188 and 189 of the Jiulonggang Mega Bridge are close to the existing Huainan Railway, the roadbed of the railway is intensified with Type-D make-shift beams during the construetion of the low capped pile foundation to ensure the safety of the operation of the railway and the construction;steel sheet cofferdams made up of type steels are used to intensify the low capped pile foundation to ensure both the safety of the operation of the existing railway and the safety of the construction of bridges and culverts. The project may serve as a useful reference for other similar projects.
