Report again!Tianshan Shengli Tunnel imported three holes in the import side of the three -hole excavation exceeded 11 kilometers

Tianshan News (Reporter Lu Zejian reported by Reporter 暴 暴 天) On July 1, the G0711 Line Urumqi to Weili Expressway Tianshan Shengli Tunnel was imported from the import side of the import side of the Tianshan Shengli Tunnel.

On the same day, at the import end of the Tianshan Shengli Tunnel, the sound of the left and right main holes of the main hole and the TBM (hard rock excavation machine) of the middle guide hole were continuously drilled. The mileage of 2762 meters, the mileage of the middle guide cave reached 5473 meters, and the three -right hole in the left, middle and right, had an increase of 11,173 meters, and successfully exceeded the 11 -kilometer mark.

Tianshan Shengli Tunnel is 22.1 kilometers in length. It is the world's longest highway tunnel under construction. It is a typical high -cold and high -altitude highway tunnel in the highway under construction in China. The geology is complicated, the geological fracture belt is crossed, and the construction is difficult. The builder adopts the "three holes+four vertical wells" construction method. The intermediate service tunnel (medium guide hole) uses TBM construction to open up auxiliary working planes for the left and right double main holes to achieve the "long tunnel short fight", which can effectively save the construction period.

The construction team of the fifth standard section of the civil construction of the Chinese Communications Urfe Cailor Project is responsible for the construction of the import side of the Tianshan Shengli Tunnel. Since entering the field, the builders have overcome difficulties such as harsh climate, high geological fracture belt, high environmental protection requirements, short validity periods, and traffic closed traffic. Fight in the depths of Tianshan Mountains with an altitude of more than 3,000 meters. "We plan in advance, organize personnel, equipment, and materials, digging at the same time in the three holes of the left, middle and right, and continuously complete the tasks of various nodes. In the second half of the year, we will continue to overcome all difficulties, work hard to build the foundation for the early opening of the tunnel. Wang Heqi, manager of the project department of the bid section.

The Wuwei Highway runs through Tianshan. It is expected to be opened to traffic in 2025. At that time, the transportation bottleneck from the north and south of Tianshan will be fully connected. The driving time between Urumqi and Korla will be shortened from the current 7 hours to 3 hours.
