Functions of Zhongshan Tunnel in Luzhou:

Yesterday (20141June 10), the reporter learned from Luzhou Construction Management Center that the tunnel under the entrance of Zhongshan Tunnel has been completed, with the left tunnel excavated 20m and the right tunnel excavated170m. According to the schedule, by the end of 20 14, the tunnel will be excavated for 500 meters, and 50% of the tunnel construction will be completed. It is expected to be completed in July next year. After the tunnel is completed, it will organically connect the central peninsula, the north of the city and the front of the sand to ease the traffic pressure in the city.

Workers are carrying out tunnel excavation, secondary lining construction and slope retaining wall construction. Yao Lei, the project leader, said that there are two major obstacles in the current project construction. The reverse construction of slope retaining wall outside the tunnel is not only affected by weather, but also restricted by construction technology, and the progress is slow; In the tunnel, the geological surrounding rock is changeable. Although the third party advanced geological prediction is adopted, it depends on the actual operation, so the construction method is often adjusted, and the pace of tunnel excavation slows down. "Zhongshan Tunnel is located in the urban area, and noise is inevitable during construction. Please forgive me. "

Luzhou Zhongshan Tunnel starts from the end of the west approach bridge of Guojiao Yangtze River Bridge, passes through Zhongshan and ends at Lianjiang Road, with a total length of 2. 15km ... Zhongshan Tunnel connects Guojiao Yangtze River Bridge and Baizitu Yangtze River Bridge. The construction of Zhongshan Tunnel is also to give full play to the role of Guojiao Yangtze River Bridge.
