Attention! The Zheduo Mountain Tunnel on G3 18 line of Sichuan-Tibet will be completed and opened to traffic in 2023!

Up to now, the single tunnel excavation and initial support have been completed in this project, accounting for 23.6% of the total length 1 1006m; 30% of subgrade earthwork is completed, and anti-slide pile and bridge and culvert works are completed 100%. The cumulative estimated investment is 65.5710.9 million yuan, accounting for 44% of the estimated investment/kloc-0 1.4755 billion yuan.

Among them, TJ 1 contract section completed single tunnel excavation of 904m, accounting for 6 166m 14.7% of the total single tunnel length, and TJ2 contract section completed single tunnel excavation of 1697m, accounting for 35.65438+ of the total single tunnel length of TJ2 contract section of 4840m.

In order to make the general public enjoy convenient travel as soon as possible, during the Spring Festival, the National Highway 3 18 Kangding Zheduo Mountain Tunnel project managed by Sichuan Jiaotou Zanggao Company did not stop. More than 70 traffic builders from all over the TJ 1 contract section stick to the front line of plateau construction.

At this time, the COVID-19 epidemic broke out suddenly, and with thoughts and concerns for family members in my heart, I persisted in "fighting the epidemic" and continued to write the legend of fighting in the snowy area. Since the outbreak, the headquarters and the project department quickly set up an epidemic prevention leading group, arranged and deployed on-site epidemic prevention work, and resolutely held the "position".

In the face of the shortage of epidemic prevention materials, through coordination with superior units and medical institutions, we raised epidemic prevention materials through multiple channels and ways, and * * * raised 3,000 medical masks, 30 kilograms of disinfectant, 200 pairs of medical gloves, 0/0 sets of protective clothing/kloc-0, and a batch of sprayers and thermometers. Strictly control access control, prohibit outsiders from entering and leaving, and restrict employees from entering and leaving; Measure the temperature of employees more than twice a day, and disinfect crowded areas such as canteens and dormitories more than three times; Promote epidemic prevention knowledge to employees through video conference and five minutes before going to work to overcome panic. ...

At present, the project is focusing on epidemic prevention and control and construction production, minimizing the negative impact of the epidemic on construction production, and making every effort to ensure the realization of the goal of the whole line of Zheduo Mountain Tunnel.

Finish the task with high quality again and again,

Behind it is the selfless dedication of the builders.

Here,

Should we tell them, too?

Thank you very much

Note: The commencement date of Zheduoshan Tunnel is 2065438+March 29th, 2008, and the construction period is five years, that is, it will be completed and opened to traffic in 2023. It's not impossible to walk from the air ditch to xinduqiao in one day when your physical strength is a little better?

There are many mountains and bends, high altitude, long ice and snow period and high altitude, which make many people unattainable and often have car accidents. It is reported that the newly-built Zheduo Mountain Tunnel is the longest secondary highway high-altitude tunnel in China, with an altitude of about 3,800 meters, and it is one of the extra-long highway tunnels with the highest seismic intensity. The design speed is 60 km/h, the subgrade width is 10 m, and the asphalt concrete pavement is adopted. The construction period of the project is 5 years, and the estimated investment is about 654.38+0.4 billion yuan.

When Zheduo Mountain Tunnel is completed and opened to traffic, the original old road will be preserved and handed over to local authorities for management. The old 3 18 national highway in Zheduo Mountain will be managed as a backup road, and the pavement will continue to be maintained. Many fans and friends who ride bicycles to road trip pass by here, and the landscape photography is hardly affected.
