Project: Qinling Mountain water transmission tunnel


This project is mainly composed of Qinling water transmission tunnel, Golden Gorge water project and Sanhekou water project。And up to 98.The 3km Qinling Mountain water tunnel has become a top priority。The maximum buried depth of the tunnel reaches 2012 meters from the ground, which needs to overcome the worldwide problems such as ultra-long distance ventilation, water gushing, mud gushing, rock burst and high temperature geothermal。The construction of the tunnel in the Qinling Mountains is the first time that man has crossed the ten major mountains of the world from the bottom。Qinling Tunnel is a milestone project in the history of water resources in the world, both in terms of engineering quantity and technical difficulty。


Project Challenges:

1, to achieve more than 20 kilometers of tunnel wireless signal coverage

2, the construction of ultra-long distance quasi-wireless intercom network in the tunnel

3. Realize barrier-free command and dispatch in the tunnel

4. Clear communication and strong navigation ability

[Beifeng Communication Emergency command and dispatch System Solution]

1.The call signal of the TBM rear set, main control room and cutter head intercom must be stable at any position。

2.The dispatching center can use the walkie-talkie to contact the intersection between the bottom of the inclined shaft and the positive hole, the dispatch duty room in the hole, the TBM master control room and the railway vehicle walkie-talkie in real time。

3.The office, living area, production area dispatching room and tunnel in the fourth hole use intercom communication throughout
