Red Net Moment News on December 20(Correspondent Pan Chunhong, Zhao Liming) some time ago the good weather provided a good construction environment for the construction of the project, and the construction party of the Zero Road Expressway (Shuangpai Section) increased manpower investment, and with the "blessing" of new equipment and new technologies, the project construction has achieved "accelerated running" to ensure that it will be completed and opened to traffic in 2027.
The mileage of the main line of zero road high-speed is 7484 kilometers, 45 bridges and 5 tunnels. Among them, the Purple Mountain No. 2 Tunnel is the longest tunnel of the Zero Road Expressway, with a length of 43 km, which is currently in full swing. In order to fully ensure the completion of the control node, the tunnel is constructed by tunneling from both ends to the middle at the same time, and the equipment and personnel work in shifts 24 hours a day, and the construction is expected to be 400 people stationed during the peak period.
Three of the five tunnels on the whole line of the zero highway are located in the five bids in the territory of Shuangpai, and the total length of the bid is 843 km, of which the tunnel is 804 kilometers, bridges and tunnels accounted for 979%。As an important nodal project, the construction progress of the tunnel project directly affects the process of pulling through the whole line. To this end, in addition to increasing manpower investment, the construction party also invested more than 200 yuan to purchase 3 intelligent steel production lines for tunnel steel arches, small conduits and steel mesh processing.
Long Jiang, the technical person in charge of the first work area of the fifth bid section, introduced that compared with the traditional manual or semi-automatic production line, this fully automated production line has realized the "addition" in quality, efficiency and safety, and the "subtraction" in manpower, construction period and management. "Its advantage lies in the full automation of all processes such as material grabbing and welding, small conduit opening, etc., and people only need to start and stop the equipment, regular maintenance, and management. We transition from managing people to pipe equipment, processing quality, appearance and strength are the best and more labor-saving, in the past, an arch production line needed seven or eight people, now basically two people can be completed. ”
The total length of the Zero Road Expressway (Shuangpai section) is 48 kilometers, and the main control works are 24 bridges, 5 tunnel works, 3 interchanges and 1 service area. Since the start of the project, Shuangpai has taken the construction of the Zero Road Expressway as the "No. 1 project", focusing on the key points of work, focusing on the key points of tasks, and closely following the time nodes. The construction party is divided into tunnel teams, earthwork teams, handyman teams and other groups according to different specialties, and simultaneously promotes the construction of roadbed, tunnel and bridge projects, and jointly presses the "acceleration button" of project construction. At the excavation site of Shuangfeng Tunnel, the construction party uses the hydraulic trolley of the excavation frame to realize the integrated construction of excavation and erection, reduce the cycle construction time, save labor, shorten the construction period and improve safety.
Xue Ming, director of the project of the seventh bid section responsible for the construction of the tunnel, said: "Now there are 18 people in the left and right holes, and it is expected that the tunnel will be fully completed in the first half of 2025." ”
