Embodiment Construction
[0021] based on the following Figure 2 ~ Figure 4 , specify the preferred embodiment of the present invention:
[0022] Such as figure 2 with image 3 As shown, it is a cross-sectional view of the bottom independent evacuation safety passage structure for a single-hole double-line maglev tunnel. The bottom independent evacuation safety passage structure is arranged in the tunnel segment structure 1, which includes a safety passage 5 and an escape platform 6;
[0023] The safety channel 5 is located between the upward track 3 and the upward track 4, and is arranged under the rail platform 2. The safety channel 5 runs through the working wells 11 at both ends longitudinally (such as Figure 4 As shown), it is connected with the lower layer of the working shaft, and the air is blown by positive pressure from the fan room of the lower layer of the working shaft to form a smoke-proof passage.
[0024] Cable trays, equipment boxes, and water supply and drainage pipes are respec...
