The invention provides a tunnel face temporary supporting device which comprises a gas generating device, an air bag and a manual control device, the gas generating device communicates with the air bag, the manual control device is in communication connection with the gas generating device, and the manual control device is used for starting the gas generating device, therefore, the gas generating device generates gas conveyed into the gas bag. The device can support the tunnel face when disasters such as collapse of the tunnel face and water burst and mud burst occur, so that disaster diffusion is reduced, the disaster degree is reduced, safety of constructors is guaranteed, and follow-up construction is facilitated.
Description
technical field [0001] The invention relates to the technical field of tunnel construction, in particular to a tunnel face temporary support device. Background technique [0002] During the excavation of tunnels with weak surrounding rocks and water-rich surrounding rocks, the tunnel face is too late to be supported or the strength of the advanced support for the tunnel face is not strong enough, and disasters such as tunnel face collapse and water gushing and mud gushing often occur, causing life-threatening injuries to construction workers. Dangerous, causing economic losses to the project and delaying the construction period. Currently, there is no corresponding measure in the prior art to deal with the above situation. Contents of the invention [0003] The purpose of the present invention is to provide a temporary support device for tunnel face, which can play a role of temporary support in case of disasters such as face collapse or water gushing and mud bursting, so...
