AI Technical Summary
The existing tunnel lining trolleys on curved sections are difficult to move stably during construction and are prone to slipping, which affects construction efficiency.
The trolley frame uses rolling wheels at its bottom to contact the tunnel floor rails, combined with lifting and supporting cylinders to support the tunnel roof. The stability of the trolley frame is improved by using hydraulic rods and locking mechanisms in conjunction with I-beam blocks.
This improved the stability of the tunnel lining trolley on curved sections, prevented slippage, and increased construction efficiency.
