调频广播隧道覆盖技术之漏缆覆盖技术及施工注意事项

Leakage Cable Covering Technology and Construction Notice in FM Broadcast Tunnel Coverage Technology

随着城市框架不断扩大,城市建设也在向纵深发展,不仅有市区内快速路、高架路,很多地方还修建了地下隧道,为市民的快速通行提供了便利。然而,有些隧道长度往往超过700m,甚至达到几千米,驾驶车辆的市民在穿越隧道时受隧道钢筋混凝土的屏蔽,进入隧道后司机和乘客朋友就无法很好地收到车载收音机的广播电台信号;同时,一旦隧道内发生较大安全事故时,如火灾、车祸等,司乘人员也无法及时得到路况信息,为了解决这一问题,调频广播隧道覆盖技术就得到了发展和应用。

With the expansion of the urban framework, urban construction is further developed in depth,not only in urban expressways and flyovers, but also in many places. However, some of the tunnel lengthsare often more than 700 meters, or even a few kilometers, the citizens of the vehicle are shielded fromthe reinforced concrete by the tunnel when they cross the tunnel, and the drivers and passengers of thepassengers are unable to receive the radio signal from the car radio. At the same time, if there is a great-er safety accident in the tunnel, such as fire, car accident, etc., the driver and conductor cannot get thetraffic information in time and in order to solve the problem.
