复杂环境下铁路圆端形薄壁空心桥墩施工技术

On construction technique of round-ended thin-wall hollow piers of railways under complicated environment

通过提前对模板进行综合性的模数组合设计,采取标准节定型钢模组合、多桥墩间大循环倒用流水的方法,进行数量多且集中的圆端形薄壁空心高墩的施工,提高了模板周转率,合理降低了施工成本,保证了墩体外形美观及施工安全。

By the previous integrated modulus composite design on frameworks,the paper adopts the standard set-shaped steel formwork assembly and the large-cycling inverted running water among piers,and undertakes various and integrated construction of round-ended thin-wall hollow piers of railways,so as to improve the turnover rate of formwork,lower the construction cost and ensure the attraction of piers and its construction safety.
