为解决传统衬砌台车在隧道衬砌施工中存在的跑模、振捣强度大、搭接部易损坏等问题，以及减少衬砌空洞、裂缝、掉块等病害，通过引进装备设计和信息化设计的理念，结合传统施工工艺，研制了一款可带压浇筑的新型隧道数字化衬砌台车。该台车具有双浇筑技术、带压入模技术、高频振捣技术、软搭接技术以及数字化控制技术，并已在湖北罗家山隧道进行初次使用，取得了良好的施工效果。双浇筑系统将混凝土浇筑时间由12 h缩短至8 h，高频振捣使混凝土充分捣固，气泡数量明显减少，有效地解决了衬砌质量问题，降低了人员劳动强度。同时，信息集成传输系统的应用，一定程度上实现了衬砌施工的机械化、信息化和智能化。

The construction of tunnel lining by traditional lining trolley has many disadvantages such as concrete leakage, large vibration intensity and easy damage of connection point, etc. Hence, a new type of digital tunnel lining trolley with pressured casting is developed based on equipment design and informatized design to reduce lining hollows, cracks and drops. The trolley is equipped with doublecasting technology, pressintomold technology, highfrequency vibrating technology, connecting by special elastic material (soft connection technology), and digital control technology. The trolley has been applied firstly to Luojiashan Tunnel in Hubei, and good effects have been achieved. The doublecasting system can reduce the casting time from 12 h to 8 h, and the highfrequency vibrating can tamp concrete fully and reduce the bubbles, which can improve the concrete quality and reduce the labor intensity. Meanwhile, the mechanization, informatization and intellectualization of lining construction have been realized to a certain extent by the application of information integrated transmission system.
