The inverted arch trestle was a type of equipment used for tunnel construction. It had the functions of automatic walking, automatic vertical movement, horizontal movement, lifting and landing, and so on. It could solve some problems in tunnel construction, such as the mutual interference between the tunnel face, inverted arch and secondary lining construction, improve construction efficiency and mechanized level, and reduce construction costs. The inverted arch trestle used hydraulic technology and a fully automatic design, which could achieve large span, flexible movement, safe and reliable tunnel construction. It could also be used with inverted arch concrete construction under various bench excavation methods to achieve the construction requirements of early closure and early ring formation. In addition, the inverted arch trestle could also make full use of the early strength of the concrete to provide support for the weight of the trestle and the traffic load, with a special flexible base and automatic running track. In general, the inverted arch trestle played an important role in the tunnel construction, improving the construction efficiency and quality.
