Tunnel gallery wireless intercom system composition

The composition of the tube tunnel:

(1) The tunnel gallery is a system consisting of three parts: manholes, hand holes, and pipelines. From the nature of use, it can be divided into user tunnel corridors and inter-office tunnel corridors.

The user tunnel tunnels include trunk tunnels and wiring duct tunnels. Main tunnel tunnels are generally constructed using multi-hole tunnel tunnels, which are used to drill amplifying the number of cores. The diameter of the pipe holes varies from 25mm to 110mm, and the spacing between manholes in the tunnel corridor is generally 100 meters. Its position is generally located on the main and secondary road sidewalks or roadways of the city. The newly-built urban pipe tunnels are generally planned on both sides.

(2) Pipeline Tunnel Wireless Intercom System Communication Construction Method:

Communication tunnels are divided into three types from the construction methods: tunnels, tube tunnels, and channel tunnels. The tunnels are complex and have a long service life, and they are located at the entry and exit points of large-scale sites. Based on reinforced concrete, the arched prefabricated parts are overlaid and the two sides are made of brick masonry.

Shanghai Ruihe Pipeline wireless Intercom System is simple in structure and convenient in network construction. It only needs to connect the equipment to the internal network to form a powerful digital communication system. It can realize computer network, emergency assistance, background music, video surveillance, and public broadcasting. The convergence application can also be extended to applications such as public telephone networks and video conferencing systems. It has successfully applied highways, intelligent transportation, pipeline corridors, prisons, customs, energy, rail, electricity, and intelligent building industries.
