The Shishan Tunnel of Huangmaohai Cross -Sea Channel is completed 53 days in advance than the original planned construction period

Yangcheng Evening News reporter Wang Danyang, correspondent Yuejiao Xuan Xuan, Han Dongdong, and Cen Jinchang reported: At 17:00 on August 8th, after 523 days of construction, the left and right lines of the Lion Tunnel of the Huangmao Sea Crossing Channel run smoothly, 53 early than the original planned construction period. The completion of the sky marks a staged progress in the construction of the Huangmao Hai Channel.

Huangmao sea cross -sea channel is about 31 kilometers long, of which about 14 kilometers of cross -sea section, 2 ultra -large cable bridges, 1 medium and long tunnels, and 4 interchange interchange.

The Shishan Tunnel is one of the two tunnels across the sea cross -sea channel of Huangmao Sea. It is located between the two reservoirs. The line passes through the Shishan Mountain. The net distance is separated from the T7 contract section of the T7 contract of Huangmao Hai, the twelfth inning of China Railway.

It is understood that in the construction of tunnels, two "black technology" developed by the project independently: the three -dimensional laser safety warning system of the tunnel, and the lining concrete wireless detection radar is first applied to the construction of domestic tunnels.

Among them, lining concrete wireless detection radar, through special detection robots carrying air coupling radar, moving forward at a uniform speed of the specified line, collecting concrete quality information. After the work is completed, the radar data will automatically return to the background for real -time data processing. Through the analysis of the background big data, the suspicious defects are judged in advance.
