Description

Technical Field

[0001] This utility model relates to the field of shield tunnel ventilation, and in particular to a TBM shield tunnel ventilation enhancement device. Background Technology

[0002] Tunnels are engineering structures buried in the earth's strata and are a form of human utilization of underground space. Tunnels can be divided into traffic tunnels, hydraulic tunnels, municipal tunnels, mining tunnels, etc. Among them, traffic tunnels are channels specifically for automobile transportation and play an important role in improving the technical condition of highways, shortening travel distances, increasing transportation capacity, and reducing accidents.

[0003] Chinese Patent Publication No. CN211874535U discloses a ventilation device for long-distance shield tunnel construction, including an arched support frame with a ventilation mechanism fixedly installed inside. The ventilation mechanism includes multiple circular mounting slots, all located at the top of the arched support frame. Horizontal mounting slots are provided on both sides of each circular mounting slot. However, existing devices have some shortcomings. During tunnel construction, a significant amount of dust is dispersed inside the tunnel, affecting air quality. Existing devices typically inject outside air into the tunnel, but this process disperses the dust again, polluting the air. Therefore, we propose a TBM (Tunnel Boring Machine) ventilation enhancement device to solve these problems. Utility Model Content
