The invention discloses underground tunnel construction equipment. The underground tunnel construction equipment structurally comprises a limiting sliding bracket, a fixed hole, a bottom plate, a splicing groove, a sliding rail, a tunnel automatic lighting device and a driving motor. Underground tunnel construction workers can control the driving motor through a remote controller to make the tunnel automatic lighting device travel on the sliding rail in order to light a construction site with the help of a lighting lamp installed on the tunnel automatic lighting device, and the lighting lamp is matched with a light sensor; and when the lighting lamp starts to work, the light sensor can induce the tunnel ambient brightness to automatically adjust the brightness of the lighting lamp, the visual effect in the tunnel is improved, operation errors of the tunnel construction workers are reduced, and the quality and safety of tunnel construction are improved advantageously.
