Description

Technical Field

[0001] The utility model belongs to the technical field of tunnel support devices, and in particular relates to a tunnel support device for underground tunnels. Background Art

[0002] Tunnels are various passages drilled between the surface and the ore body, which are used for ore transportation, ventilation, drainage, pedestrians, and various necessary preparatory works for the new excavation of ore for metallurgical equipment. When processing underground tunnels, it is necessary to process the underground tunnels, so support devices are needed to provide auxiliary support for the underground tunnels.

[0003] In the support device, by neatly installing the support sub-plates on the cross plates and adjusting the height of the support device, the support sub-plates are driven to contact the top of the tunnel, and then the sub-plates can play a role in supporting and protecting the tunnel. However, due to the different overall widths of the tunnels, this will cause the spacing between the support devices to need to be adjusted, and at the same time, the position between each group of cross plates will change. When the spacing between the cross plates is too large, it will cause the compressive resistance between the cross plates to be unbalanced, which will lead to insufficient overall stability of the support device. For this reason, we propose a tunnel support device for underground tunnels. Summary of the invention
