为解决传统的混凝土衬砌施工时边墙振捣安全性及其他工序车辆通行受阻等问题，以丽江至香格里拉铁路站前工程LXZQ-2标中义隧道工程为依托，通过对隧道混凝土衬砌施工工艺和台车结构进行系统分析和研究，确定单线铁路隧道模架一体化新型衬砌台车的设计方案和参数。该台车具有模架一体化技术以及新型便捷式振捣技术，并在中义隧道进行现场应用。结果表明： 1）该台车内部净空增大，装载机以及出碴车能够轻松通过台车底部，杜绝了磕碰等隐患； 2）关、拆模较旧台车提前2 h左右； 3）采用质量轻、42 V低电压新型振捣棒，安全性更高，同时借助于弹力卷筒、导向装置的作用可以大大降低工人振捣时的劳动强度。

In order to guarantee the vibrating safety of sidewall and the normal running of vehicles during concrete lining construction, the design scheme and parameters of a new type of lining trolley with formworkframe integration for Zhongyi singletrack railway tunnel of LXZQ2 Bid Section on LijiangShangrila Railway are developed by systematically analyze the concrete lining construction and lining trolley structure. The trolley is equipped by formworkframe integration technology and the new convenient vibrating technology, which has been applied to Zhongyi Tunnel. The applicable results show that: (1) The internal clearance of the trolley is increased, the loader and the slagcarrying vehicles can easily pass through the bottom of the trolley to prevent hidden dangers such as bumps. (2) Two hours can be saved when carrying out formwork closing and demolishing comparing to the old trolley. (3) The safety can be improved by adopting new vibrator with light weight and 42 V low voltage; at the same time, the labor intensity of the workers can be greatly reduced by the action of the elastic reel and the guiding device.
