On November 16 local time, Chinese President Xi Jinping and Indonesian President Joko Widodo jointly witnessed the test run of the Jakarta-Bandung High-Speed Railway in Bali, Indonesia by video, and watched a video showcasing the cooperation results between the two countries.
With a total length of 142 kilometers and a maximum designed speed of 350 kilometers per hour, the railway connecting the capital Jakarta and Bandung is the first HSR in Indonesia and Southeast Asia, and a project of China's HSR to implement the whole system, all elements and the entire industrial chain overseas for the first time. CRHIC has been responsible for the provision of all high-speed turnout products, bridge erecting machines, girder transport vehicles, carriers and girder cranes for the railway, the transfer and erection of 2,025 box girders, and the only steel truss girder fabrication and installation engineering with a span of 84m along the whole line.
High-speed Turnout
China Railway Shanhaiguan Bridge Group Co., Ltd. (CRSBG), a subsidiary of CRHIC, has manufactured all high-speed turnout products for the railway. The turnout products developed and manufactured for Jakarta-Bandung High-Speed Railway have seen sharp improvements in service performance and service life through overall line type design and internal structure design. Moreover, CRSBG has developed a new process route, drawn up detailed process parameters, designed special tools and process equipment, and enabled numerical control and standardization of all rail parts processing. With the above efforts, the requirements of high smoothness, high comfort and long life for exported high-speed turnout are met, and the product design and product quality have been so far the highest manufacture level in the turnout industry.
Transport, Lifting and Erection Equipment
China Railway Science and Industry Group Co., Ltd. affiliated to CRHIC has provided construction equipment such as bridge erecting machine, beam transport vehicle, transporter and girder lifting machine for the railway. By combining the technical advantages of the third generation tunnel-crossing transport and erection equipment and China's first kiloton-grade transport and erection equipment, the JQS900 tunnel-crossing transport and erection equipment tailored for the Jakarta-Bandung High-Speed Railway features light weight, reliable performance, strong adaptability to complex working conditions, and can fully adapt to the railway's special working conditions such as 30 ‰ ramp, R1300m small curve and girder erection at tunnel entrance. In total, the high-quality transport and erection equipment has completed the erection of 2,084 box girders and accomplished the difficult erection for the only box girder crossing the existing railway and the longest box girder crossing the expressway along the line in an efficient and safe manner.
Steel Bridge
China Railway Jiujiang Bridge Engineering Co., Ltd. under CRHIC mainly undertakes the only steel truss girder fabrication and installation engineering with a span of 84m along the entire line. The steel truss girder is 85.4m long, and has a calculated span of 84m and a through double-track simply-supported girder. The on-site erection adopts the drag method. Specifically, a 150t truck crane is used to assemble steel nose girder and steel truss girder of the first four intersegments on the assembly platform in sequence. After the assembly and connection are completed and pass inspection, the continuous jack is commissioned for drag construction. The erection was successfully completed on October 19, 2021. It is the first time to apply drag method in Indonesia.
