On July 22, 2021, the DK8+768 continuous beam of the Yawan high-speed rail pipe section contracted by the Eighth Bureau of Hydropower was closed, which left plenty of time for the construction of the cast-in-place beam.

The DK8+768 continuous beam system consists of two continuous beam main piers and three bridge spans. The spans are 46+70+44m respectively, the piers are 19.5m high, and the entire continuous beam is 161.6m long. The continuous beam is located in the urban area of Jakarta, and the design of the line is across the dense local traffic area: the small mileage (Jakarta) direction side spans across two expressway elevated ramps and a planned elevated ramp; the 70m main span spans the local 10-lane expressway elevated , One of the continuous beam main piers is less than 1m from the nearest elevated ramp, resulting in extremely limited installation space for the pier formwork here. The on-site construction personnel innovated the pier formwork installation method and successfully completed the main pier pier pouring; large mileage (Bandung) ) The direction side spans across an elevated ramp.

The overall construction conditions of the DK8+768 continuous beam are complicated, and it is close to the 40m cast-in-place beam site (not cast) in the direction of the small mileage (Jakarta). With the smooth closing of three continuous beams in July, 17 continuous beams have been closed in 25 continuous beams in the section of the Eighth Hydropower Bureau, and the remaining 8 continuous beams have entered the mid-to-late stage of construction. It is planned to close 4 continuous beams by the end of this month.

The smooth closing of the DK8+768 continuous beam is another major progress made by the Eighth Hydropower Bureau in its efforts to promote the construction of the project, providing a solid guarantee for the promotion of subsequent construction. Next, the Yawan High-speed Railway Project Department of the Eighth Hydropower Bureau will further strengthen communication with all parties in Indonesia, pay attention to the analysis of the new situation of epidemic prevention and control in real time, and complete the construction tasks with high standards and strict requirements to show a good construction image of a central enterprise.
