Have you collected enough formwork for the second lining trolley of the tunnel at one time?

Tunnel lining trolley is an important lining tool for concrete secondary lining in tunnel construction. Due to the different tunnel sections, tunnel lining trolleys are divided into single-track railway trolleys, double-track railway trolleys, double-track expressway trolleys, three-track expressway trolleys, water conservancy and hydropower diversion tunnel trolleys, mine lining trolleys, full-circle needle beam trolleys and so on. Because of the different section and curve radius of the tunnel, it is decided that the tunnel lining trolley is specially customized and produced. If there is a tunnel lining with similar tunnel section and curve radius, the original trolley can be used on the similar tunnel lining according to the new tunnel section, and it can be modified slightly! Some suggestions, I hope the landlord will adopt them. In addition, about half of domestic tunnel lining trolleys are produced in Luoyang, so Luoyang is also known as the base of tunnel lining trolleys.
