China Economic Net, August 31 (Reporter Tong Mingbiao) According to China Railway International Co., Ltd., Indonesian local time on the evening of August 25, with the completion of the last board lining, the Yawan High -speed Railway 2 tunnel project was completed, and the entire line opened the entire line The beam channel also marks the "sales number" of the heavy difficulty project of the Yawan high -speed railway, which laid a solid foundation for the completion of the traffic in 2023.

According to reports, there are 13 new tunnels on the Yawan high -speed rail, with a total length of 1,6643 meters. Among them, the No. 2 tunnel of Yawan High -speed Railway is located in Powaltada County, Western, Indonesia. The total length is 1052 meters and the maximum burial depth is 53.6 meters. It is a single hole and two -line design. The frequent situation is one of the most difficult control projects in the entire line, and it is also the last tunnel of the entire line.

The construction unit pioneered "using the use of steel pipe pipe piles to simplify the upper half -sided bilateral wall guide pit excavation method", and adopts the initial support of the unspecified loop of the steel pipe concrete pile to prevent the expansion soil enclosure tunnel from deforming. A virtuous circle of "fast digging, fast -telled, fast -to -form". After the tunnel penetrated, they used the work tasks such as leaning arches, disassembling arches, and two -lining in nearly 70 days to smoothly open the entire beam channel.

At present, the 13 tunnels of the Yawan high -speed rail are completed, and the number of civil construction projects of road bases, bridges, and stations is more than 90%. The main line has begun to laid rails. The construction of the project has been fully transferred from offline construction to the online construction stage. The station building and four -power projects are implemented steadily, and the operation and maintenance preparation work is carried out in an orderly manner. The high -speed EMU and comprehensive testing trains tailored for the Yawan high -speed rail had successfully went offline and were launched to Indonesia on August 21.

The Yawan high -speed rail connects the Indonesian capital Jakarta and the fourth largest city Bandung, with a total length of 142 kilometers and a maximum design speed of 350 kilometers per hour. After the project is completed, Jaca's trip time will be shortened from more than 3 hours to 40 minutes.
