What is the function of tunnel formwork trolley? In other words, what is the use of the template trolley?

Tunnel formwork trolley is a special equipment that must be used in the construction of tunnel secondary lining. Generally, it is designed as a steel arch frame, with standard combined steel formwork, no automatic walking, and external power dragging. All formwork removal is manual operation, with high labor intensity. Therefore, it is generally used in short tunnel construction, especially in tunnel concrete lining construction with complex plane and space geometry, frequent process conversion and strict process requirements, and its advantages are more obvious.
