Description

Technical Field

[0001] The utility model relates to the technical field of tunnel construction platforms, in particular to a portable tunnel construction platform. Background Art

[0002] The existing tunnel construction platform does not have its own power supply and adjustable lighting structure. The environment in the tunnel is relatively dim.
