The invention relates to the technical field of tunnel lining, in particular to a construction method and device for preventing tunnel lining cracks, and the construction method comprises the following steps: step 1, cleaning impurities adhered to the inner wall of a tunnel, and building a supporting framework in the tunnel by using reinforcing steel bars; secondly, a buffering arc plate is installed on the top wall in the tunnel, and the buffering arc plate is fixed to the supporting framework; thirdly, a cooling water pipe is installed in the gap of the supporting framework, and the cooling water pipe extends in the length direction of the tunnel; and fourthly, a supporting formwork is installed at the bottom of the supporting framework, a protruding plate is arranged at the top end of the supporting formwork, and grouting holes are reserved in the supporting formwork. According to the construction method and device for preventing the tunnel lining from cracking, the buffering arc plate is arranged, and the
