The construction of 16 stations at the first phase of Metro Line 7 started construction

Changsha Evening News, Changsha, August 20 (All -Media reporter Chen Huanming Correspondent Yuan Ang Qian Yang Ke) On August 20, at the construction site of the South Plaza of the Comprehensive Transportation Hub of Changsha Automobile South Station, the construction site of the South Railway Station of Metro Line 7, more than 60 workers On the top of the head, the crown beam supports the pouring, and prepares for the main foundation pit of the station's main body. The reporter learned from the Changsha Rail Group on the 20th that the first phase of the first phase of the Changsha Metro Line 7 (Yuntang Station -Wuli Pai Station) has all started construction, laying a solid foundation for the subsequent boom of the main construction.

Line 7 will be seamlessly transferred with Changzhitan City Railway

The first phase of the Changsha Metro Line 7 starts from Tianxin District Yuntang Station in the south, and the north along Huijin Road, Shaoshan Road and Bayi Road to the north. Take 9 stations), the geological conditions and environment along the line are relatively complicated, land acquisition and demolition, transportation, pipeline relocation, greening migration are difficult, and they have passed through the Changzhutan Intercity Railway, the Beijing -Guangzhou Railway and the Changsha Metro 2, 3, and 4 , Line 6, the total investment of the project is 16.4 billion yuan, designed as the first fully autonomous driving line in Changsha.

"In the future, Metro Line 7 will pass 2 underground channels at the South Railway Station Hall, which will be transferred to the existing comprehensive transportation hub of the South Railway Station and the Changzhutan Intercity Railway to achieve seamless connection." Liu Yuxian, a technical person in charge of the technical area of ​​the second standard section, told reporters that the South Railway Station of Line 7 is the underground two -story three -cross -outdoor platform station. The enclosure is the first station of the 16 stations of the first phase of Line 7 to achieve the full surrounding of the main body of the station, and it is also the first station to realize the main body surrounding structure piles in the entire line.

In order to cope with the high temperature weather and prevent heat stroke and thermal radiation disease, the project department adopted the wrong time construction method in order to cope with the high temperature weather at the moment. "We avoided the high temperature period at noon, and construction was constructed from 6 am to 11 am and 15:00 pm to 19 pm. We prepared herbal tea in the construction site rest area, cool salt content, watermelon, mung bean porridge, etc., and also prepared Huoxiang Zhengqi Water and other heatstrokes and labor insurance products. "Liu Yuxian said that the South Railway Station of Line 7 has now completed green relocation, traffic relocation, and some pipelines. Enter the foundation pit excavation construction stage in September.

Three stations are undergoing the main earthen earth excavation

"Since the construction of construction last year, the headquarters led the party building, and further promoted the" party building aggregation "project with the participating parties. Construction organization and factor configuration, so as to plan in advance and take the initiative, provide a strong guarantee for the rapid entry of the project, and the safe and efficient promotion of on -site. " The 16 stations across the first phase of the project have entered the construction stage. Among them, 3 stations are undergoing the main earthquake excavation, 12 stations for main enclosure structure construction, and 1 stations carry out pipeline relocation and transportation construction.

The first phase of the Changsha Metro Line 7 was fully realized, and the "acceleration key" was pressed for subsequent construction promotion. The relevant person in charge of the construction headquarters of Line 7 stated that the next step will work together with the construction characteristics of the construction of the construction of high temperatures, and reasonably adjust the schedule of high temperature and open -air operators, and appropriately reduce or avoid on -site operations under high temperature and high heat conditions under high temperature and high heat conditions. , Effectively do the labor protection and heatstroke prevention of front -line operators to ensure effective protection, rational storage of materials, and normal work in high temperature weather. Safe, efficient, and orderly quickly set off a large boom in construction. Strategies to show rail power.
