In recent years, China has participated in railway and other infrastructure projects in many countries. Although the epidemic has affected the resumption of work and production in many countries since 2020, China is still continuing to promote a number of infrastructure projects. According to reports, Indonesia’s Jakarta-Bandung High-speed Rail Tunnel No. 7 was successfully completed on the 15th. This is the first tunnel of more than one kilometer across the entire line of the China Railway Indonesia Jakarta-Bandung high-speed rail project, and it is another important staged progress in the construction of the Jabban high-speed rail.

The No. 7 tunnel of the Yawan High-speed Railway has a total length of 1285 meters. The geology of the cave is clay, mudstone and andesite. Since the start of construction, the engineers and technicians of China Railway have adopted a variety of construction methods to ensure construction progress and construction safety according to the characteristics of different locations, overcome many difficulties, and strictly follow the design and specifications. During the construction process, the China Railway Project Department trained 260 local Indonesian skilled workers, which played an important role in the tunnel penetration.

This is the third tunnel completed by the China Railway Indonesia-Jaban High-speed Railway Project Department after the completion of the Valini Tunnel on May 11, 2019 and the No. 5 Tunnel on March 12, 2020. M above the tunnel.

The Jakarta-Bandung High-speed Railway, which connects Jakarta, the capital of Indonesia, and Bandung, the fourth largest city, has a total length of 142.3 kilometers. Sex engineering. The project design speed is 350 kilometers per hour.

The Jakarta-Bandung high-speed rail project ushered in the smooth completion of the tunnel over a kilometer, which is enough to prove the speed of China's infrastructure construction. After the completion and opening to traffic, the time from Jakarta to Bandung will be shortened from the current three hours to about 40 minutes. Editor/Sang Xiaomei
