Description

Technical Field

[0001] The invention relates to the field of tunnel construction, and in particular to an automatic slag collection and transmission device for tunnel under-excavation treatment. Background Art

[0002] Tunnel construction refers to the general term for the construction methods, construction technology and construction management of building tunnels and underground caverns. It is a complex and technology-intensive engineering process that usually involves multiple stages and links.

[0003] During the tunnel construction process, it is necessary to cross different strata and the geological conditions are complex and changeable. In order to avoid stratum collapse and mud leakage during the excavation process when encountering karst areas, coal mine tunnels, fault fracture zones or areas with poor surrounding rock stability, which will affect the stability of the section after tunnel construction, a conservative excavation plan is usually adopted. After the tunnel body is excavated using a conservative plan, it is easy for the cross-sectional perimeter of the tunnel body to be smaller than the designed size, that is, the tunnel is under-excavated.

[0004] In the prior art, when the tunnel is undercut, manual drilling with auxiliary rock drilling equipment such as shovels, pickaxes, and crowbars is usually used to further construct the tunnel so that the tunnel construction meets the design requirements. The slag and debris generated during the tunnel undercut construction process are transported to trucks or other transportation mechanisms and then transported to the outside of the tunnel.

[0005] With regard to the above-mentioned prior art, the operation of tunnel under-excavation construction is cumbersome, and it is not convenient to quickly transport the slag and debris generated during the construction process, resulting in low work efficiency. Summary of the invention
