摘要
地铁隧道的公众通信网络是通过泄漏电缆+POI方式实现信号覆盖,但因现场条件限制,在隧道中敷设泄漏电缆时存在挂高位置不合理、无法精准对车厢辐射信号、现场施工难度大、不能实现和其它专业线缆有效分离、存在侵界等诸多问题。为了有效解决上述问题,结合现场实际情况,特对地铁隧道的四电托架创新设计为一体式挂耳托架,从而实现公网泄漏电缆科学、快速敷设,应用后不仅节省了建设投资、规避了安全风险,同时也实现了公网通信的最佳覆盖效果。
The public communication network of subway tunnel realizes signal coverage by means of leaky cable + POI. However, due to site conditions, there are many problems when laying leaky cable in the tunnel, such as unreasonable hanging position, inability to accurately radiate signals to carriages, great difficulty in on-site construction, inability to effectively separate from other professional cables, boundary invasion and so on. In order to effectively solve the above problems, combined with the actual situation of the site, the four electric brackets of the subway tunnel are innovatively designed as an integrated lug bracket, so as to realize the scientific and rapid laying of public network leakage cables. After application, it not only saves construction investment and avoids safety risks, but also realizes the best coverage effect of public network communication.
