May 23，And is lif out along with that upper cover of the shield steel sleeve，Shenzhen Metro Line 3 Low Carbon City Station constructed by China Railway Shanhe～The left line of Baishitang Station was successfully completed.，Complete the node task on schedule，Escort the smooth completion of the whole project。

The Shenzhen Metro Line 3 Extension Project undertaken by China Railway Shanhe consists of two sections.。Among，Low Carbon City Station~Baishitang Station Section is a double-track tunnel.，Interval left line length 1168.50 meters，The right line is 1148 meters long.，Maximum burial depth 17.4 meters。The shield machine starts from Baishitang Station.，Interval needs to underpass karst development area、Pingxi Bridge、Pingxi Bridge（Box culvert）、Building buildings and factory buildings、Upper soft and lower hard strata and rivers, etc.，Finally arrived“Carbon Peak Carbon Neutralization Pilot Demonstration Area”Shenzhen International Low Carbon City--Low Carbon City Station。

“In the process of tunneling，The shield machine needs to cross the river successively.、Urban trunk roads, etc，High construction risk、Difficult。”China Railway Shanhe Project Department responsible person said.，Since its launch on October 28, 2022，We have always adhered to high standards of construction.，High quality management，Concentrate superior resources to fight hard battles for project construction and production。

According to the recollections of the staff of the，During the Spring Festival last year，In order to ensure the construction progress,，All managers stick to their posts.，The preparatory work for construction during the Spring Festival will be completed in advance.，Construction personnel continued to work during the Spring Festival.，Complete the tunneling production task。

In view of the stratum change and the need to cross the river in the process of excavation、Major risk sources such as bridges，The project department is optimized by technology.、Expert research and information monitoring as a means，Strengthen on-site management and supervision，Continuous optimization of shield tunneling parameters，Strict implementation of established programmes and measures，Ensure the safety, stability and orderliness of tunneling construction。

In addition，The project department continuously strengthens the management and control of the construction site.，Strictly implement various safety and quality management systems，Optimize the conversion and connection of construction procedures，On the premise of ensuring safety and quality，Reasonable allocation of construction resources，The maximum number of single-shift tunneling rings in this section is more than 8.。

At present，Low-Another shield on the right line of the white section is advancing rapidly as scheduled.。Next step，China Railway Shanhe Project Department will refine the node construction period target，Scientific organization of construction，With“Keep safe、Quality assurance、Protect the node”It is the focus of work，Keep improving、Do solid work，Make every effort to speed up project construction，Continue to contribute to the construction of Guangdong-Hong Kong-Macao Greater Bay Area。
