Abstract: In the construction of long tunnels, the air flow at the working face is blocked by the lining formwork trolley, which results in poor working environment. Therefore, new type of lining formwork trolley is developed to improve the working environment. The structure, assembling requirements, labor organization, assistant equipment and assembling procedure of the new type of lining formwork trolley are presented, with the case of the exit section of Funing tunnel on KunmingNanning railway as an example. The assembling practice demonstrates that the assembling method described is efficient, timesaving and flexible and can completely meet the tunneling requirements. The application of the new type of lining formwork trolley can greatly improve the ventilation effects of the tunnel. 

Key words: new type of lining formwork trolley, hoisting equipment, formwork assembling
