双孔圆形隧洞针梁式钢模台车联合衬砌工法

Joint lining construction method of steel-mould stair vehicles of needle bridge in double-hole circular tunnel

该工法以资中县城北水资源综合开发利用工程——水库联网输水工程隧洞衬砌施工为素材,对双孔圆形隧洞采用两台针梁式钢模台车联合进行混凝土衬砌的施工方法进行了总结,并对注意事项做出分析,提出控制措施,为类似工程施工提供参考。

The method is based on reservoir networked water conveyance project tunnel lining construction--Chengbei Water Resources Comprehensive Development and Utilization Project in Zizhong County as basic materials. The construction method of joint concrete lining by two steel-mould stair vehicles of needle bridge in double-hole circular tunnels is summarized. Precautions are analyzed, control measures are proposed, thereby providing reference for similar project construction.
