明挖大断面双洞式框架通道模板台车施工技术研究

Research on Construction technique of formwork trolley for open cut twin-hole frame passages with a large section

为提高大断面明挖地下通道的施工效率及质量,以厦门某明挖双洞式框架下穿通道工程为依托,设计了移动式模板台车,相比传统的满堂钢管支架现浇施工,其具有节约成本、占用施工场地少和材料可回收周转使用的优势,可为工程实际提供参考。

In order to improve the construction efficiency and quality of large section open cut underpass,based on an open cut double hole frame underpass project in Xiamen,a mobile formwork trolley is designed.Compared with the traditional cast-in-situ construction of full hall steel pipe support,it has the advantages of cost saving,less occupation of construction site and recyclable materials,which can provide reference for the actual project..
