某半埋—全埋式大截面箱涵施工技术

The construction technology of a partly-fully buried heavy-section box culvert

详细介绍了一个作为某双层公路桥和地铁隧道之间过渡结构的大截面箱涵的施工技术,在箱涵基坑开挖的过程中采用了施工桥,便于在有两层水平支撑的基坑内实施开挖作业,箱涵主体分两阶段施工,保证了工程质量。

This paper deals with the construction technology of a partly-fully buried box culvert which is a transition structure between a two-deck bridge and a underground tunnel.For the purpose of excavation of the foundation ditch with two-story lateral bracing,an accessory bridge was adopted as a working platform.The main structure was constructed in two-steps which contributed to good quality.
