blue arch-made sea mood
car to continue moving forward, after 2 and 3, pumping station, go to the lowest point of the tunnel.

Soon, reporters found that the tunnel arch has become a dark blue, the car feels like in the sea during passage in the walk through.
in the wall, the construction workers are installing a decorative plate, far from looking like a decoration with white tiles. 3 meters tall, four or five centimeters thick, is connected with the blue arch, blue and white is very nice. Shield because of the brightness with the enamel, it is particularly bright, but it will not cause reflective dazzling effect. Its main function is to protect the inner wall of the tunnel on both sides and will also cover the inner wall of the pipeline to ensure beautiful.
radar test project quality
Minister on, according to Qi, the tunnel will need to install the equipment within the many and complex, including fire systems, lighting systems, power supply system, drainage system, ventilation systems, charging systems and signal systems. At present, the power supply system has started pre-stent, power pipe trench, trough, such as construction; the most important drainage system has also been pouring finished pumping station; fire protection system in addition to spray fire retardant paint, but still the two main Tunnel car dealers and arranged for the construction of walkways, through these channels in the left lane, right lane two main walking through tunnels and service tunnel to escape.
equipped with fire escape routes for each box, box dragon playing with water, foam and so on. In addition, the management center is equipped with remote monitoring, in the event of a fire alarm at the first time. Chinese New Year does not lay
1 �� 29 �� ���� 11 ʱ 40 points in the tunnel pumping station at the No. 2, China Railway Bureau Electrical Department staff are having lunch in Chung Li. Project workers stay prepared for the Ministry of rich dinner and a celebration will be issued in the New Year's Eve festival fees. p> ban non-construction workers and vehicles enter the tunnel
Tunnel intense mechanical and electrical equipment currently being installed and interior work inside the cave, working stand more construction vehicles have been frequent, do not have the traffic conditions, so the construction personnel and vehicles of non-prohibited access, please be understanding and support of the community.

Secret
tunnel is all decorated with high-tech finish can be delayed by two hours of fire
, are both very strong fire resistance, and its targets are higher than the national standard. Paint can be delayed for two hours fire protection of concrete of the main tunnel. Fire performance of porcelain enamel finish better than blue difference be laid within the tunnel also has a fire resistance of asphalt concrete, and its comfort, slip resistance, corrosion resistance is much higher than conventional asphalt.
Minister on, according to Qi, the blue paint spraying is the arch deal with the final steps. In order to fully achieve the fire effect, arch finish processing to include three major processes, paint mixed with a fire retardant materials.
infiltration water will discharge back into the sea
present, the tunnel of power within the trench on both sides of the road has been completed, workers are installing the sink. By design, the water inside the tunnel will be closed through the tank platoon, widening project on the 10 cm thick asphalt, the pavement should be slightly higher than the sink, the road surface water can easily flow into the sink. and then row back to the sea after the final.
pump is imported. Tunnel, including terminals, including a total of four pumping stations, water seepage in the tunnel together through the drainage pipes to pumping stations, pumping stations pumped through a special place for precipitation, purification, the final row back to the sea.
LED lights that automatically adjust the brightness
Xuejiadao at a distance not far from the export, the reporter found the light with a meter long. This bright band, not only arch has been sprayed with blue paint, enamel steel wall installed, but the surface of the blue arch also installed two rows of the new LED lights.
