The utility model discloses a tunnel construction structure of a thermal insulation concrete pouring support, which comprises a main tunnel and a branch tunnel, and the branch tunnel is communicated with the main tunnel at an acute angle; the system further comprises a traffic pilot tunnel. One end of the traffic pilot tunnel is communicated with the branch tunnel, and the other end of the traffic pilot tunnel is communicated with the branch tunnel, so that the branch tunnel and the main tunnel are communicated by the traffic pilot tunnel in acute angle distribution of the tunnel and the main tunnel, and the end part of the traffic pilot tunnel far away from the outer side of acute angle distribution of the branch tunnel and the main tunnel is arc-shaped. Due to the fact that the branch tunnels and the main tunnel which are distributed in the acute angle mode are communicated through the traffic pilot tunnel, and the end of the traffic pilot tunnel is in the arc shape, vehicles for construction and transporta
