| titleOfInvention | Air curtain test device and test method for high-speed railway tunnel in cold region |
| abstract | The invention relates to an air curtain test device for a high-speed railway tunnel in a cold region, comprising a tunnel formed by surrounding rock, an air curtain machine for blocking air flow inside and outside the tunnel, and a surrounding rock ground temperature control device for controlling the ground temperature of the tunnel. The surrounding rock is placed in the refrigerating room, and the surrounding rock ground temperature control device includes a water storage space and a water pump, the water storage space is arranged on the periphery of the tunnel, and the tunnel ground temperature is controlled by controlling the water temperature of the water storage space, and by The temperature of the refrigerating chamber is controlled to control the external temperature of the tunnel, the surrounding rock is provided with a temperature test point, and the tunnel hole is provided with a wind speed test point. The invention provides experimental data and theoretical support for solving the problem of tunnel freezing damage in cold regions. |
