At present, the new Austrian composite lining is widely applied all over the world. However, the new Austrian method has the advantages of multiple construction procedures, complex construction organization, longer construction period, severe construction environment, and ineffective guarantee of construction quality, but has better geological adaptability and unique advantages of economy and flexibility. The TBM method has simple process, high construction speed and good safety, but is generally only used for a round long tunnel mainly made of hard rock and is not suitable for short tunnels and underground engineering with complex geological conditions. In order to adapt to various geological conditions, accelerate construction speed and improve engineering quality, some improvements on the currently popular construction method or lining structure form are necessary to obtain good economic and technical benefits.

Meanwhile, with the development of tunnel construction mechanization and construction factory technology, the fabricated lining is more and more widely applied to various tunnels and underground engineering. Fabricated tunnel linings have many advantages: (1) Once assembled, the pressure of the surrounding rock can be borne without the need of curing time; (2) A large number of components can be produced in batches in a factory and mechanically assembled, so that the labor condition is improved, and the labor force is saved; (3) During assembly, temporary supports such as an arch frame, a template and the like are not needed, so that a large amount of supporting materials and labor force are saved; (4) The assembly speed is improved due to the adoption of mechanization, the construction period is shortened, and the manufacturing cost can be reduced; (5) The fabricated lining has strong adaptability and can be adopted in some special environments such as severe cold and the like.
In order to facilitate the installation of the assembled tunnel lining, at present, a ring of tunnel lining sheets can be divided into a plurality of blocks to be respectively assembled, and the assembly of 1 ring of tunnel lining sheets often comprises the assembly of 1 arch lining sheet and 2 side lining sheets, so that a trolley capable of installing the arch lining sheets and the side lining sheets is very necessary to solve the problems of speed, quality and benefit in the current engineering construction.
