Abstract: For the sake of the application of the selfpropelled sidewall formwork trolley, accurate and rapid construction of Metro structures can be realized, the construction efficiency of the sidewalls can be improved and the quality of the Metro structures can be guaranteed. In the paper, detailed study is made on the components, design principle, stress calculation and operation of the selfpropelled sidewall formwork trolley. Conclusions drawn are as follows: 1) Due to the application of the sidewall formwork trolley, timely and effective concrete curing is achieved, which minimizes the shrinkage cracks and water seeping points; 2) Due to the application of the sidewall formwork trolley, the quality of the sidewall is improved; 3) The sidewall formwork trolley discussed is easy in operation and maintenance. 

Key words: selfpropelled sidewall formwork trolley, Metro structure, sidewall, finite element calculation
