Description

A mine backstage frame that is easy to assemble

technical field

The utility model relates to the technical field of stands, in particular to a mine backstage stand which is easy to assemble.

Background technique

The usual process of mine construction is to use wood or steel members as temporary supports in the tunnel formed after the blasting operation, and then carry out excavation and excavation work in the tunnel. The temporary support is withdrawn, and the overall reinforcement is done in other ways at the same time. For the excavation construction of large-section shafts in mines, it is necessary to transport the equipment, materials, tools, etc. The requirements for excavation strength, excavation method and excavation efficiency are also constantly increasing.

In the existing construction, a bench is set up in the shaft. The bench is a temporary high platform built with wood or steel components, including a bottom support and a column arranged on the bottom support. A workbench is arranged on the top of the column.
