On August 18, the Shenzhen Metro Line 10, which was constructed by China Railway Second Bureau, was successfully opened for operation, which further improved Shenzhen's rail transit network.

The opening and operation of Shenzhen Metro Line 10 has achieved 2 "Shenzhen No. 1" and 3 "National First". The two "Shenzhen No. 1", namely Shenzhen's first north-south 8A marshalling line, and the Shenzhen Metro's first double-shield TBM construction method. The three "National Firsts" are the country's first multi-storey integrated depot, the country's first fully underground double-deck subway parking lot, and the country's first cloud computing rail transit line.

During the construction of Metro Line 10, a total of 15 large and small geological fracture zones and 2 large geological faults were crossed. At the same time, technical problems such as water and mud in bad formations were overcome. Among them, the section between Maling Station and Yabao Station has high rock formations, and has to cross Jigong Mountain and the busy Xiamen-Shenzhen Railway, which has a high construction difficulty coefficient. To this end, Shenzhen Metro has conducted a large number of investigations, deductions and demonstrations in conjunction with construction units, and for the first time in China, the double-shield TBM method was used in innovative construction and successfully completed the tunneling task. Reasonably plan the construction area and carry out construction in different areas to reduce mutual interference. In the face of long construction fronts, multiple specialties, and tight schedules under the influence of the new crown pneumonia epidemic, the China Railway Second Bureau Electric Company, which is responsible for the installation of system equipment across the entire line, is equipped with sufficient management capabilities to allocate high-quality resources to key positions and carry out labor competitions. Solved the construction problem. The solution of the series of problems has greatly improved the construction efficiency and laid a solid foundation for the smooth opening of Shenzhen Metro Line 10.

At the same time, China Railway Second Bureau actively carried out technological innovation on the one hand, and pioneered the adoption of a fully enclosed construction of shaft shelters in the Shenzhen subway, which minimizes the impact of construction on the surrounding environment while ensuring safe and civilized construction; TBM can be implemented in rocky areas "No blasting" construction, the work efficiency is 5-8 times that of the traditional drilling and blasting method, saving about 180 days of construction period under the condition of ensuring safety, fully interpreting the "Shenzhen speed" driven by innovation, and pushing Shenzhen rail transit construction to To a higher level. On the other hand, China Railway Second Bureau continues to strengthen environmental protection construction operations, strengthen supervision and control, implement environmental protection responsibilities and measures, and implement green construction throughout the entire process of project construction.

Metro Line 10 starts at Futian Port Station, passes through Futian District and Longgang District, and ends at Shuangyong Street Station. The line is 29.3 kilometers long and has 24 stations (Gangxia North Station has not yet opened). This line combines the functions of a trunk line and a local area line. It is the city's first north-south line with 8A formation. After opening, it will end the history of no subway access to the east of Pinghu, Banxuegang, Huawei New Town and Meilin Pass. By then, it will only take 54 minutes to reach Pinghu from Futian Port, which will greatly ease the traffic pressure from Futian Central Area to Bantian Section and become another "North-South Artery" of Shenzhen rail transit.
