Formwork trolley for open-cut double-arch tunnel and construction method
The invention discloses an open-cut double-arch tunnel formwork trolley and a construction method, and relates to the technical field of tunnel construction. The open-cut double-arch tunnel formwork trolley comprises an outer formwork trolley body and two inner formwork trolley bodies. The outer mold trolley comprises an outer mold portal, an outer mold lifting walking mechanism arranged at the bottom of the outer mold portal, an outer mold plate assembly arranged in the outer mold portal and an outer mold telescopic supporting device connected between the outer mold portal and the outer mold plate assembly. The inner mold trolley comprises an inner mold portal, an inner mold lifting walking mechanism arranged at the bottom of the inner mold portal, an inner mold plate assembly arranged outside the inner mold portal and an inner mold telescopic supporting device connected between the inner mold portal and the inner mold plate assembly. A pouring space used for pouring a middle partition wall and two arch walls is formed between the outer formwork assembly and the two inner formwork assemblies. The construction efficiency is improved, construction joints are prevented from being formed between the mid-partition wall and the arch wall, the waterproofness and durability of the tunnel are improved, and the later maintenance cost is reduced.
本申请公开了一种明挖双连拱隧道模板台车及施工方法，涉及隧道施工技术领域。该明挖双连拱隧道模板台车，包括外模台车和两个内模台车；外模台车包括外模门架，设置在外模门架底部的外模升降行走机构，设置在外模门架内的外模板组件，连接在外模门架与外模板组件之间的外模伸缩支撑装置；内模台车包括内模门架，设置在内模门架底部的内模升降行走机构，设置在内模门架外的内模板组件，连接在内模门架与内模板组件之间的内模伸缩支撑装置；外模板组件与两个内模板组件之间形成用于浇筑中隔墙和两个拱墙的浇筑空间。本申请不仅提高了施工效率，而且避免在中隔墙与拱墙之间形成施工缝，提高了隧道的防水性和耐久性，降低了后期的维护成本。
