Core Viewpoint - The successful completion of the "tunnel breakthrough" for the Hangzhou Metro Line 9 Phase II marks a significant milestone, indicating that the entire line is now connected and ready for further construction phases [1][2] Group 1: Project Overview - The Hangzhou Metro Line 9 Phase II spans approximately 10 kilometers, consisting entirely of underground sections with a total of 7 stations [1] - The stations include: Kangxin Road Station, Xingyuan Road Station, Kangtai Road Station, Xinghebei Road Station, Xingsheng Road Station, Xinchao Road Station, and Tangqi Station, with an average station spacing of 1.44 kilometers [1] - The specific section that achieved the breakthrough is between Xingyuan Road Station and Kangtai Road Station, with a tunnel length of about 1.6 kilometers [1] Group 2: Construction Challenges and Solutions - The project faced multiple construction challenges due to complex geological conditions in the Linping area, which includes various soil types such as silt and sand [1] - To address these challenges, a comprehensive analysis of geological conditions and existing structures was conducted, leading to enhanced control over the shield machine parameters to ensure safety [2] Group 3: Future Developments - The construction progress of Line 9 Phase II is ahead of schedule by six months, with an expected operational readiness by the end of 2026, although actual opening will depend on other factors [2] - Once completed, the total length of Line 9 will reach 39.6 kilometers, significantly improving connectivity between Donghu New City and the main urban area, and establishing Linping as a transportation hub in northern Hangzhou [2]

Group 1 - The construction of the second phase of Metro Line 9 in Hangzhou has made significant progress, with the completion of the main structure of the Kangxin Road Station and multiple station foundation excavations underway [1] - The second phase of Metro Line 9 runs underground in Linping District, with a total of 7 stations and no transfer stations, enhancing local transportation infrastructure [1] - The first phase of Metro Line 15 has also seen progress, with several stations entering the main foundation excavation phase, including successful condition acceptance for the foundation excavation at Jingfang Station [1] Group 2 - The first phase of Metro Line 18 is progressing well, featuring a north-south route that connects key areas and integrates with other rail services, with a total length of approximately 48 kilometers and 19 stations planned [2] - Significant milestones have been achieved in the construction of Metro Line 10's third phase, with the successful initiation of the fourth shield machine and the completion of the main structure at Renhe Station [2] - The construction of Metro Line 10 has reached a new phase with simultaneous excavation of multiple shield machines, indicating a major breakthrough in project development [2]

Group 1 - The Hangzhou Metro Phase IV project has made significant progress, with three lines entering new construction stages: Line 4 Phase III, Line 9 Phase II, and Line 18 Phase I [1] Group 2 - Line 4 Phase III consists of a south extension and a west extension, totaling 5 kilometers each, with 4 stations on each segment, all constructed underground. The main structure of the first station, Puju Street Station, was successfully capped on July 28, 2025 [2] Group 3 - Line 9 Phase II is located in the Linping District of Hangzhou, stretching approximately 10 kilometers with 7 underground stations. The left line of the section from Xingchao Road Station to Tangqi Station has passed the shield tunneling conditions verification on July 24, marking the start of the 10th shield tunneling [3] Group 4 - Line 18 Phase I runs from Yiqiao Station in Xiaoshan District to Century Avenue Station in Linping District, covering about 48 kilometers with 19 stations. The northern foundation pit of Huajiachi Station passed the excavation condition verification on July 27, laying a solid foundation for subsequent construction [4]
