摘要
本项目是新建高架桥梁跨越原有结构物,因场地不足无法使用传统支撑墩,进而采用单排钢管,因新建桥梁所处平曲线半径较小纵坡较大,为便于标高调整和拆模,门洞上部施工采用碗扣式脚手架和贝雷片组合的支撑方式,保证施工快速架设的同时保证了费用的节省。
This project is a new viaduct across the original structures. The lack of space cannot support the use of traditional square pier. Then a single row of steel is applied. Because the new bridge has larger longi-tudinal and small horizontal curve radius, for ease of elevation adjustment and form removal, the upper openings of scaffold construction is using a combination of support and Bailey way to ensure rapid construc-tion erection and saving costs.
