During the construction of tunnels, due to the tight situation of urban land use and the high cost of land, many tunnels have small turning radius and bottom clearance, and large-scale pavers are unable to pave the asphalt surface layer. When constructing the asphalt surface layer of this section of road, manual paving is often used, and the construction quality cannot be guaranteed. Therefore, the present invention is to invent an asphalt paving construction machine suitable for construction in tunnels with a small turning radius, which can perform bottom clearance and small corner radius asphalt surface paving construction when large-scale pavers cannot meet the paving construction conditions. The invention has a simple structure, is easy to construct, and can effectively ensure the construction quality of the asphalt surface layer in the tunnel.
