Good news Changsha Metro Line 6 will operate in the early stages of passengers at the end of the month! Today, let's review the precious shots in the construction of Line 6!

Changsha Metro Line 6 is 48.11 kilometers in length. There are 34 stations on the entire line. From the west, Meixi Lake District and Huanghua International Airport are the longest line under construction in Changsha Metro. After the line is completed and opened, the Hexi Intercity Rail Hub and Huanghua Airport will be connected in series to effectively strengthen the connection between Hexi's sub -center and the city's main center.

In the past five years, Line 6 construction company and participating units have been difficult to overcome. Today, let's review the "blockbusters" of Line 6 builders to overcome:

Cross the river 5 times

Line 6 has successively wore high -rich water risk areas such as the Xiangjiang River, Guitang River, Liuyang River, Shiba River, and Laomubahe.

More than 20 times through municipal engineering

More than 20 times on Line 6 through municipal bridges and underground tunnels, such as the West Second Ring Road, Renmin Road-Station Road, Wanjiali Viaduct, Guitang River Viaduct, Renmin East Road, Ringcheng High-speed Bridge, Magnetic Floating Viaduct, Airport, Airport Viaducts and so on.

8 times crossing railway trunk and highways

Wearing the Beijing -Guangzhou Railway, the Changzhutan Intercity Railway, the Beijing -Hong Kong -Macao Expressway, Changzhu High Speed, and crossing the Wuguang High Speed Railway.

5 times through the existing operating subway line

Line 6 crosses all the operating subway lines in Changsha Metro, namely Line 1, 2, 3, 4, and 5.

For the first time, the bilateral wall guidance pit secretly excavated construction method for station construction

In order to protect the ecological greening in the park to the greatest extent, the southern station of Martyr Park took the first time in the Changsha Metro. The bilateral wall -on -pit darkening construction method was used for the construction of the main structure of the station.

For the first time, large -size rectangular top pipe construction construction

The construction of rectangular top pipe machines for the first time in Shaoguang Station and Chaoyang Village Station of Line 6 uses the rectangular top pipelines to reduce the impact on traffic, underground pipelines and road environment, and greatly reduce the construction period of the main roads of the people's road and the movement of pipelines.

The first time use BROKK robot excavation

The range from the Xiangya Third Hospital to the Liugou Station is the most difficult to dig excavation range in Line 6, and the construction is difficult and the safety risks are high. To this end, the construction unit has repeatedly invited well -known domestic experts to discuss to introduce the first advanced device BROKK robot in the construction of the Changsha Metro. The 360 ° full -range multifunctional and high -precision operation is further improved to further improve the safety factor of excavation.

Line 6 is one of the most important lines in the Changsha Rail Transit Network plan. It also creates multiple "most":

The largest total investment budget, the longest line mileage, and the largest number of stations and transfer stations. The total investment of Line 6 is 36.9 billion yuan, and the total length of the line is 48.11km, involving the "five districts and one county" in Changsha. There are 34 stations and 13 transfer stations, which are transferred to 9 subway lines, 1 magnetic floating lines, and 2 intercity lines.

The engineering environment is complicated and the construction of the project is the most difficult. Line 6 crosses 1 high -speed rail, 2 railways, 5 subways, 5 rivers, 3 highways, and 3 highways with Xiangya Crossing Channel and Line 6 structures. The large section high in the south station of the park is 19.78m, 25.42m wide, and an area of about 418 square meters. It is rare in the country.

As the "urban window type" backbone line where the Changsha Rail Transit Network is going on, it also creates multiple "more":

More smart -station panoramic holographic control. Line 6 is the first "smart subway" in Changsha. The stations panoramic management, smart digital inspection, smart switch station ... Build a "smart station"; line holographic perception, smart passenger service, emergency command "A picture "... build a" smart line "," black technology "is full.

More intelligent -concentrated use of advanced technology. Face recognition, visualization, intelligent voice alarm, VR risk source experience, successive use, "sense of technology" burst; Beidou positioning system, enclosure spraying system, dust noise monitoring system, large volume concrete temperature monitoring system, successively applied, successively applied, successively applied, successively applied, successively applied. "Wisdom" is full.

More quiet -the line reduction and noise reduction throughout the line. The entire line uses special, higher, and medium vibration-reducing tracks, and the vibration reduction effect is generally 8-20 decibels. The Changsha Metro also adopts cross -interval seamless lines on Line 6 for the first time, and uses a CPIII measurement rail construction process. The measurement accuracy mentioned 0.1 millimeters from the 1mm level. Make everyone more comfortable.

More energy saving -comprehensive application of environmental protection technology. The entire line uses high-efficiency energy-saving power distribution transformers, and the air load energy consumption is reduced by 20%; the mid-voltage inverter device is used to recover the train braking energy to electric energy reuse; , Precise adjustment temperature; the signal system uses full electronic lock to reduce the energy consumption of equipment, and "energy -saving artifacts" create Changsha green smart subway.
