Putian Railway Station The first passage of the railway-related pre-embedding project was completed
On October 5th, with the "Tianfei No. 4" pipe jacking machine on the right line of the pipe jacking section of the east channel breaking ground, the Putian Railway Station's railway-related pre-embedding project broke out. The first passage was successfully connected. This also marks the first attempt in my country to use the super-large cross-section earth pressure balance and the slotted double-mode hard rock pipe jacking machine to achieve a new breakthrough in the construction of the underpass railway.
As a provincial and municipal key project, the railway-related pre-buried project of Putian Railway Station includes the railway-related pre-buried project of the east and west underpasses on the north and south squares of Putian Railway Station and the supporting pre-buried project of Putian Railway Station (F2 Line). Among them, the total length of the underground passage on the east side is 820 meters, the single-line length of the rectangular pipe jacking section is 212 meters (double-line 414 meters), the rest are open-cut and buried sections + U-shaped groove sections, and the open-cut section is 18.6-28.72 meters wide. layer structure.
Restricted by many factors such as construction environment, geological conditions, safety risks, and technical difficulties, the construction of the railway-related pre-embedded project in Putian Railway Station is facing huge challenges. To this end, China Railway No. 2 Bureau cooperated with top equipment manufacturers at home and abroad to study the plan, and tailored the project for the project. The excavation section is 12.6 meters wide and 7.65 meters high. Die hard rock pipe jacking machine. The powerful rock breaking capacity and driving efficiency of the equipment can not only meet the construction requirements of the project under complex geological conditions, but also greatly reduce the disturbance of the stratum caused by the driving construction, which effectively guarantees the operation safety of the existing Hangzhou-Shenzhen railway.
After the project is completed, it will break the partition between the north and south areas of Putian Railway Station, effectively integrate various transportation modes such as high-speed railway, rail transit, highway passenger transport, ground bus, etc., build a three-dimensional interactive modern transportation network system, and realize the integration of transportation resources in the area. Co-construction and sharing and interconnection of transportation facilities will promote the development and construction of the high-speed rail area.
