摘要
在介绍了攀枝花新庄大桥的工程维修加固概况之后,叙述了该桥维修加固过程中,T梁拆除和安装由原计划无支架缆索吊装方案变更为汽车吊装方案的实施过程。汽车吊装方案能安全、迅速实现T梁拆除和安装,缩短了工期并节约了成本。
The article introduces the general situation of the engineering maintenance and reinforcement of Panzhihua Xinzhuang Bridge,and describes the implementing process of T-beam dismantlement and installation by the truck crane scheme instead of the original planned non-support cable hoisting scheme in the course of this bridge maintenance and reinforcement.The truck crane scheme can safely and quickly realize the dismantlement and installation of T-beam,and shorten the constructing period and economize the cost.
