People's Daily Online, Jakarta, May 10 (Reporter Xu Wei) On May 10, the first multi-span rigid frame continuous beam on the entire Jakarta-Bandung high-speed rail line in Indonesia was successfully closed. The significant progress marks that the construction of the No. 2 extra-large bridge, the longest of the project, has entered a critical stage.

　　It is understood that the Yawan High-speed Railway No. 2 Super Bridge has a total length of 35.763 kilometers. This time, the rigid frame continuous beam of Helong was constructed by the Yawan High-speed Railway Project Department of China Power Construction Group. The continuous beam is 213.8 meters long and spans two expressway ramps. And an overpass, the land transportation network is dense, the traffic flow is large, the construction environment is complex, and the safety risk is high. The main span of the continuous beam is constructed by the cantilever hanging basket method, and the side span is constructed by the bracket cast-in-place method. In order to promote the safe, high-quality and efficient construction of the project, the Chinese construction team has carried out key research on continuous beam construction. Collaborate to ensure safety and quality oversight is in place.
​
　　The Jakarta-Bandung high-speed railway is 142 kilometers long, of which the bridge is 87.6 kilometers long, accounting for 61.6% of the total. There are 28 continuous beams on the whole line, 2 of which have been closed, and 26 are under construction. In particular, the No. 2 extra-large bridge, which is close to expressways and densely populated areas, crosses overpasses, expressway interchange ramps and rivers many times.

　　At present, despite the severe situation of COVID-19 prevention and control in Indonesia, the Chinese companies participating in the construction of the Jakarta-Bandung high-speed railway have further strengthened communication and contact with all parties in Indonesia, carefully analyzed and evaluated the impact of the epidemic on the project construction, and optimized and adjusted the construction organization in a scientific and reasonable manner. Actively strive to do a good job in epidemic prevention and control and engineering construction.

　　The Jakarta-Bandung high-speed railway, as the flagship project of the development strategy alignment between China and Indonesia and the joint construction of the "Belt and Road", has attracted widespread attention from China, Indonesia, and even the world. The TS-K100 series ultrasonic hole-forming and groove-forming detector, TS-S1206(B) foundation pile ultrasonic multi-tube cycler and other testing instruments have ensured the smooth construction of the project. The excellent performance and reliable quality of our company's products have received Unanimously praised by all users.

　　During the epidemic, our employees overcame difficulties and found new ways to use online distance teaching guidance to actively provide customers with instrument training and guidance to ensure the normal use of instruments!
