On December 18, the Qingyu Tunnel of the Provincial Highway 204 Nuoshui Avenue Project undertaken by the Mechanized Construction Branch of Sichuan Road and Bridge Group was successfully completed, and so far, the four tunnels of the Nuoshui Avenue Project (Fuyang Tunnel, Banqiao No. 1 Tunnel, Banqiao No. 2 Tunnel, and Qingyu Tunnel) have all been completed.
Qingyu Tunnel is located in Qingyu Town, Tongjiang County, Bazhong City, the left tunnel is 755 meters long, and the right tunnel is 740 meters long. The geological structure of the tunnel is complex, the entrance end is a shallow buried section, located in the large landslide section, and there are many houses above, the exit end is located in the slope dangerous rock zone, and the village road is not passed below, the risk of penetration is high, and the construction of the whole project is difficult.
We dispatched elite technical forces to sit on the front line, in accordance with the construction methods of weak blasting, pipe advancement, short footage, strong support, early closure, and diligent measurement, high standards and strict requirements to guard the bottom line of project quality, and after 7 months of continuous struggle, the tunnel was successfully completed. Zhou Peng, secretary of the Party branch of the Sichuan Luqiao Nuoshui Avenue Project, said.
It is understood that the total length of Nuoshui Avenue on Provincial Highway 204 is 528 kilometers, a total of 4 tunnels, the total length of 15,516 meters, the proportion of tunnels is 148%。The double-width breakthrough of the Qingyu Tunnel also marks the completion of all the tunnels, which is of great significance for speeding up the construction of the whole line of Nuoshui Avenue and laying a solid foundation for the opening of the whole line. Up to now, 15 kilometers from Tongjiang County to Fuyang Town have been opened to traffic, and the remaining 27 kilometers are being accelerated.
After the whole line is opened to traffic, the driving time between Tongjiang County and Nuoshui River Scenic Area will be shortened from 2 hours to 40 minutes, which will play an important role in improving the layout of the red tourism road network in Tongjiang County, realizing the integration of traffic and tourism and the comprehensive utilization of resources, and implementing the strategic development of rural revitalization.
