The total length of 9464 meters of Jinye Railway Shangwu Village Tunnel runs through

During the Mid -Autumn Festival holiday, the nationwide "double -layer high container" transportation railway, which was built by the China Railway Beijing Engineering Bureau -the exit of the Shangwu Village Tunnel of the Jinye Railway to the oblique well section. At this point The opening of the Jinye Railway has laid a solid foundation.

It is understood that the total length of the Shangwu Village Tunnel is 9464 meters. It is one of the control projects of the Golden -Emperor Railway. It belongs to the II risk tunnel. The construction organization is difficult, the geological conditions are complex and changeable, and the safety risk pressure is large. This is the largest length of nearly 3000 meters, which is also the longest tunnel of the Jinhua section.

Since the construction of construction in October 2019, the project department has actively overcome many difficulties such as long -uniform digging distance, high ventilation difficulty, poor environment in the cave, and difficulty in pumping water. Process control, establish information control systems such as personnel positioning, fence measurement, pre -geological forecasting, video surveillance, etc. to ensure the safety construction standards, and the whole line is the first to enable the two -way intelligence anti -off -air warning device to effectively ensure the construction of the two -lined concrete construction. Under the premise of ensuring the progress, the zero accident completed the node goal. The full tunnel executed the light blasting process and the initial wet spray process, and the green construction of the tunnel was realized. During the construction process, the project department combined with design drawings, over -reporting information, and palm -sized sketching of the surrounding rocks. The fault, the densely intensive section, and the seepage section were adopted. In accordance with the principles of "rock change," the design plan has been optimized many times, and the 9 -handed layer and 8 -festival dense belt are successfully optimized. At the same time, the project's party branch gives full play to the leading role of party building demonstrations, finds positioning and contributions in helping labor competitions and construction, providing guarantee for the smooth progress of construction progress, and ensuring the smooth realization of node goals.

As the first domestic double -layer high -box container transportation pilot, after the Jinye Railway is put into operation, it will effectively reduce the cost of transportation of container railway by more than 30%and further improve Ningbo's railway freight capacity and efficiency. The distribution center of the west to the sea railway. The Jinye Railway is an important project that implements the national strategy of integrated the development of the Yangtze River Delta and improves the layout of the regional railway network. It is a convenient strategic port channel, inter -regional fast channel, and intercity railway inside the Yangtze River Delta in Ningbo Zhoushan Port. After opening to the traffic, the transportation distance between Ningbo and Beilun to the central Zhejiang, Jiangxi, Jiangsu, Hunan, and southwestern regions will be achieved, and the connection between Yiwu and Zhoushan Port will be realized.
