Switching device of roadbed ventilation pipe and roadbed comprising switching device
The invention provides a switching device of a roadbed ventilation pipe and a roadbed comprising the same. The switching device comprises a pipe body, and the pipe body is arranged in the roadbed; the ventilation openings are formed in the two ends of the pipe body, and automatic switching devices are arranged on the ventilation openings; and when the temperature is higher than a certain temperature, the automatic switch device expands and blocks the ventilation opening, so that the pipe body is closed. The roadbed comprises the switching device. The device can be automatically closed and opened according to the external temperature condition, and has high durability and response efficiency under the severe plateau environment condition.
本发明提出了一种路基通风管的开关装置及包含其的路基，所述开关装置包括管体，所述管体设置在路基中；以及设置在所述管体的两端的通风口，所述通风口上设置有自动开关装置；其中，所述自动开关装置在高于一定的温度时膨胀，并且堵住所述通风口，从而关闭管体。所述路基包括所述开关装置。本发明能够根据外界温度情况自动关闭和开启，在高原恶劣环境条件下具有较高的耐久性能以及响应效率。
