Oh, let’s take a look at the “weekly shift line” today—— ✨ Line 16 ✨👇👇👇 01 the first prefabricated and assembled concrete column monolithic track bed in Shenzhen successfully passed the first piece acceptance.
On September 1, the construction of metro line 16 “passed the good news again” – the first prefabricated and assembled concrete column monolithic track bed in Shenzhen successfully passed the first piece acceptance and officially won the “birth certificate” for batch construction.
This has laid a solid foundation for accelerating the construction of track projects along the whole line 💪 It is understood that the monolithic track bed with prefabricated and assembled concrete columns for the track project of Tianxin depot of metro line 16 has passed the first piece acceptance, which is the first monolithic track bed of this type in Shenzhen.
Compared with the traditional cast-in-situ columns, the prefabricated and assembled concrete columns adopt factory standardized production, which can effectively ensure the quality and control accuracy, realize accurate positioning and rapid installation during construction, and greatly improve the construction efficiency while improving the quality ↗ △ the first prefabricated and assembled concrete column monolithic track bed in Shenzhen.
Due to the dense wall columns, complex tunnels and narrow site, it is impossible to use large equipment for construction.
How to ensure the accuracy of track line has become the top priority.
Therefore, the construction unit carried out technical research on construction survey, tooling design, rough adjustment of precast slab and fine adjustment of line in the early stage, continuously optimized the construction scheme, and controlled the track line error of precast assembled concrete column monolithic track bed within the design range of millimeter level.
△ technicians exchanged plans on site.
Metro Line 0216 will connect Longgang and Pingshan areas.
Metro line 16 will be led out from Dayun station and laid along Longgang Avenue, Huangge road and Longping road.
After passing through the old center of Longgang, it will go south along Shenzhen Shantou highway to Pingshan station, and after passing through the central area of Pingshan, it will be laid along Dongzong Road, Jintian road and other roads to the terminal Tianxin station.
The total length of the line is about 29.2km, with 24 stations, including 10 transfer stations, 1 parking lot and 1 depot.
The line adopts full-automatic operation mode, with a total of 4 track laying bases and 12 auxiliary track laying bases.
The total length of the whole track line is about 86 km.
It is expected to complete the goal of track connection of the whole line by the end of 2021 ⏩ △ schematic diagram of metro line 16 (station name is subject to actual operation) up to now, 100% of the station capping of the whole line and 97.6% of the section connection have been completed.
47% of the enclosure structure of ancillary works, 20% of earth excavation, 8.6% of the main body and 27% of the structural masonry of decoration works have been completed.
Among them, the track laying of the whole line has been completed for 1830m ✅ Among them, 47 of the 50 single track sections have been connected, and 23 stations along the whole line have been capped.
Line 16 is expected to be completed and opened to traffic in 2023.
At that time, the travel of people in Pingshan and Longgang will be more convenient.
At the same time, it will further promote the economy of the areas along Pingshan and Longgang and help Shenzhen’s “Eastward Strategy”! Source: Shenzhen rail transit office & China Railway Construction South Co., Ltd.
