The invention discloses a tunnel construction supporting device. The tunnel construction supporting device comprises a supporting frame, a supporting base, a height adjusting mechanism, a stable supporting mechanism and a side wall attaching supporting assembly, the supporting base is of a hollow structure, moving wheels are arranged below the bottom wall of the supporting base, a stretchable groove is formed in the bottom wall of the supporting base, the stable supporting mechanism is arranged in the supporting base, the height adjusting mechanism is arranged on the supporting base, the supporting frame is arranged on the height adjusting mechanism, and the side wall attaching supporting assembly is arranged on the top wall and the side walls of the supporting frame. The invention relates to the technical field of tunnel construction equipment, and particularly provides the tunnel construction supporting device which has dual functions of stable supporting and convenient fast type movement, and can meet the supporting requirements of tunnels with inner walls of different heights and different inclined gradients.
Description
technical field [0001] The invention relates to the technical field of tunnel construction equipment, in particular to a tunnel construction support device. Background technique [0002] Tunnel is an engineering building buried in the ground, and it is a form of human use of underground space. Tunnels can be divided into traffic tunnels, hydraulic tunnels, municipal tunnels, and mine tunnels. During tunnel construction, it is often encountered due to There is no solid foundation support, so in the process of new stress formation, the bearing capacity of the foundation is insufficient and correspondingly leads to practical problems such as tunnel instability and collapse, which seriously affects the safety of people and equipment, and hinders the progress of construction. [0003] In addition, different tunnels have different degrees of avoidance of inclination as well as tunnel heights and widths. Therefore, in the case of tunnel construction, the support stability of the s...
