It is an important part of the "Eight Vertical and Eight Horizontal" high-speed railway channel in the national "Medium and long-term Railway Network Plan", including the Bao (Yin) Hai channel and the Jingkun channel.

　　Second lining and visualization equipment layout Pouring equipment: use the No.3 top-penetrating equipment of formwork 3 for construction, without changing the pouring pipe, and pour the pipe all the way through; the No.1 top-penetrating equipment of formwork 7 is on standby.

　　Construction monitoring equipment: No.4 visualization equipment of template 1 and No.2 visualization equipment of template 5 to monitor the whole construction process.

　　The secondary lining top-charging equipment meets the requirements for pouring and charging. Using a concrete hose, approximately 2 meters in length, laid horizontally on the platform, effectively reduces the impact on concrete pumping and meets on-site needs. The use of a vibrator effectively addresses the issue of concrete accumulation. The complete implementation of video functionality provides on-site operations with visual evidence, enhancing construction efficiency.
