A walking support and a horizontally moving oil cylinder are arranged under the main body of the gantry. Inverted arch side templates are arranged on both sides of the main body of the gantry, so that the gantry can move back and forth, left and right. The tunnel inverted arch self-propelled frame has a simple structure, low cost, and low failure rate. While ensuring vehicle traffic, inverted arch construction can be carried out, which can effectively ensure the construction speed of the tunnel and effectively reduce construction accidents.
