[0002] A tunnel is an engineering structure buried in the stratum and is a form of human utilization of underground space. Tunnels can be divided into traffic tunnels, hydraulic tunnels, municipal tunnels, mine tunnels, and military tunnels.

[0003] When building a highway tunnel, in order to ensure the safety of construction, a support structure is usually required. For the convenience of carrying, most of the existing support structures are single-board settings. When performing large-area support, multiple support single boards need to be assembled. When assembling the existing support single boards, holes need to be drilled and then connected by bolts, which is rather cumbersome in operation and not easy to disassemble after use. To solve the above problems, a support structure for the reconstruction and expansion construction of highway tunnels is proposed. Content of the Utility Model
