The fire door is used for communicating two single-line interval tunnels and dividing the communication interval into independent fire-proof and smoke-proof subareas.
The two-leaf incongruous fireproof door installed in the interval communication channel is influenced by piston wind during train traveling, and compared with an ordinary fireproof door, the door leaf bears larger wind pressure load. Referring to table 1, table 1 is a table listing the relationship between vehicle speed and wind pressure.
| Vehicle speed-Km/h | 80 | 120 | 180 |
| Single line wind pressure-Pa | 309 | 695 | 1563 |
| Double-line wind pressure-Pa | 708 | 1390 | 3126 |
