Reinforcing method for tunnel cable trough formwork structure

The invention discloses a reinforcing method of a tunnel cable trough template structure, which comprises the following steps of: leaning a plurality of supporting pieces on the side wall of a tunnel, and supporting the side surface of the cable trough template structure towards the side wall of the tunnel; a plurality of clamping pieces are limited on the ground of the side, deviating from the tunnel side wall, of the cable trough formwork structure and abut against the side face, deviating from the tunnel side wall, of the cable trough formwork structure; and a plurality of traction devices with the same number as the plurality of clamping pieces are fixed on the side wall of the tunnel, and the traction end of each traction device is correspondingly connected with one clamping piece, so that the plurality of clamping pieces are pulled through the plurality of traction devices, the plurality of clamping pieces and the plurality of supporting pieces clamp the cable trough template structure, and the cable tr
