以往国内斜拉桥组合梁散件悬臂安装均采用桥面克灵吊,该工艺虽然成熟,但存在多方面的局限性。在进行吊机整体构造、局部构造分析比选后,创新设计了含底篮的悬拼吊机,并成功应用在宁波清水浦大桥(全焊钢结构)组合梁散件悬拼工艺上,其工艺安全、可控、经济、适用。 In the past, the cantilever installation of the composite cable-stayed bridge in China all adopted the bridge crane Ling crane. Although the technology is mature, it has many limitations. After carrying out the overall construction and local structure analysis and comparison of the crane, the suspension crane with the baskets was innovatively designed and successfully applied to the suspension assembly process of the composite beam of the Qingshui Pu Bridge (all-welded steel structure) in Ningbo. Process safety, controllable, economical, suitable.
