为实现敞开式TBM掘进与现浇仰拱同步施工，提升现浇仰拱衬砌质量，缩短工程工期，结合长大敞开式TBM水工隧洞现浇仰拱施工边界条件，研制大跨径现浇仰拱全工序施工装备。从功能要求、主桥、支腿、前后爬坡轨、行走系统、仰拱衬砌等方面对现浇仰拱全工序施工装备开展详细设计，提出将主桥行车路面抬高，在主桥下部设置11个长度12 m功能作业区的创新思路，并在现场进行充分验证。工程实践表明： 1）全工序现浇仰拱装备主桥支撑系统、行走驱动系统、模板浇筑系统使用效果初步达到设计预期； 2）全工序现浇仰拱装备组装效率高、整体移动便捷、与现场施工工序契合度高、人员作业空间大，劳动强度低，施工进度最高可达到240 m/月，有效提升了TBM施工现浇仰拱技术的发展水平； 3）全工序施工装备作为水工隧洞全新的工装，开创了新的施工工艺。但是该装备使本来狭窄的隧道显得更为拥挤，掘进施工交通流量受限，导致浇筑混凝土、钢筋、轨排的运输与TBM掘进物料运输之间的矛盾逐步显现，保障施工通道和TBM掘进有效进度匹配性的问题有待进一步研究。

To achieve synchronous construction of open tunnel boring machine(TBM) excavation and castinplace inverted arch, improve the quality of castinplace inverted arch lining, and shorten the project period, the authors designed and developed construction equipment for the entire castinplace inverted arch with large span based on the boundary conditions of castinplace inverted arch construction in long hydraulic tunnels bored by open TBMs. A detailed design of the construction equipment for the entire castinplace inverted arch is conducted based on the functional requirements, main beam, support legs, front and rear climbing rails, walking system, and inverted arch lining. Finally, an innovative idea is proposed to raise the main bridge crane road surface and set up 11 12mlong functional operation areas under the main bridge, which is fully validated on site. The engineering practice achieves the following results: (1) The main bridge support system, walking drive system, and formwork pouring system of the entire process of castinplace inverted arch equipment preliminarily exhibit a good applicable effect. (2) The construction equipment for the entire process of castinplace inverted arch has various advantages such as high assembly efficiency, easy overall movement, high compatibility with the onsite construction process, adequate operating space, and low labor intensity. This helps in realizing an advancing length of 240 m per month and improving the castinplace technology of the inverted arch by TBM construction. However, the equipment occupies a certain space, thereby limiting construction traffic and material transport, which needs to be further studied.
