Qiongzhou Strait Cross-Sea Bridge

The "Qiongzhou Strait Cross-Sea Engineering Planning Study Report," jointly prepared by the Ministry of Transport, the Ministry of Railways, and the provinces of Guangdong and Hainan, has now been completed. The report identifies the construction of a combined road and rail bridge connecting Denglujiao in Xuwens County, Guangdong Province, to Daolunjiao in Chengmai County, Hainan Province, as the preferred solution for the Qiongzhou Strait cross-sea project. The bridge’s offshore section will span 26.3 kilometers—making it the second-longest bridge in the world, behind only the newly completed Hangzhou Bay Bridge.

Beijing Metro Line 10 Phase II: First Section of Tunnel Boring Machine Passage Fully Connected

Good news has arrived from the construction site of Section 17, Phase II of Beijing Subway Line 10, managed by Beijing Zhuzong Municipal Engineering Company—the first tunnel segment for the entire second phase of Line 10 has been successfully completed. As the Tiantun No. 7 tunnel boring machine (TBM) began operation, its cutterhead broke through the soil and gradually entered the pre-installed tunnel portal ring, seemingly smiling with joy as it marked this significant milestone. This breakthrough also signifies the smooth completion of the right-line tunnel section between Huoqiying Station and the terminal point for this particular section. The right-line tunnel section in this segment measures 940.187 meters, while the left-line stretches 963.289 meters, totaling 1,903.476 meters in combined length. The TBM was launched on February 22, 2010, from the right-line starting point near Bagou Village. During its journey, it safely navigated under several critical infrastructure elements, including the northbound track of Landing Factory North Road, the Kunyu River, and the southbound track of Landing Factory North Road. Additionally, it passed closely alongside one to two-story buildings belonging to the Haidian Branch Office of the Beijing Municipal Transportation Bureau, as well as beneath the west-side bridge piers of the Wanquan River Interchange overpass—each posing unique challenges. Throughout the process, the TBM encountered an intricate network of underground utilities, including 41 separate pipelines such as telecommunications cables, power lines, water supply and drainage systems, and gas pipes. Notably, five of these were rainwater and sewage pipelines, each exceeding 1 meter in diameter.
