Problems solved by technology
[0003] The traditional support structure is supported by overlapping scaffolding, which is cumbersome to set up and disassemble, and cannot be erected quickly. At the same time, different support structures need to be built for tunnel roofs with different radians, which makes construction troublesome.

The invention discloses a tunnel supporting structure for civil air defense engineering tunnel construction. The tunnel supporting structure comprises a dome plate for supporting a tunnel roof and a deformation power mechanism for driving the dome plate to deform. According to the tunnel supporting structure for civil air defense engineering tunnel construction, by arranging the dome plate and the deformation power mechanism comprising movable plates, second threaded sleeves and two-way lead screws, deformation of the dome plate is achieved, the dome plate is suitable for supporting tunnel roofs of different radians, good adaptability is achieved, and a supporting structure can be conveniently and rapidly erected; a center supporting roller synchronously moving with the dome plate is arranged to support the center of the top of the dome plate, the supporting strength of the dome plate is guaranteed, and the stability of the supporting structure is improved; and meanwhile, auxiliary supporting rollers, telescopic rods, sleeves and springs are arranged to increase supporting of the dome plate, and the supporting strength and stability are further improved.
Description
technical field [0001] The invention relates to the field of civil air defense engineering tunnel construction equipment, in particular to a tunnel support structure for civil air defense engineering tunnel construction. Background technique [0002] In the construction of civil air defense engineering tunnels, it is necessary to use supporting structures to support the tunnels to ensure the strength of the tunnels and facilitate construction. [0003] The traditional support structure is supported by overlapping scaffolding, which is cumbersome to build and disassemble, and cannot be erected quickly. At the same time, different support structures need to be built for tunnel roofs with different radians, which is troublesome in construction. Contents of the invention [0004] Based on the deficiencies in the prior art mentioned in the background art above, the present invention provides a tunnel support structure for civil air defense engineering tunnel construction.
