City (suburban) Railway Chengde Line ushered in new progress
Sichuan Jianyuan Station to Wuzhou Plaza Station
Left-line shield tunnelSuccessfully completed
At this point, the entire shield construction has been completed by 60.7%
In addition, Wuzhou Plaza Station
On the basis of completing the main structure construction
The construction of the auxiliary structure has been completed recently
Become the first station on the entire line to fully complete structural construction
Shield construction exceeds 60%
The left line tunnel of the steepest interval of the Deyang section is penetrated

Chengde Line Deyang Section (main line)
Shield tunnel with the largest slope
Sichuan Jianyuan Station to Wuzhou Plaza Station
Left line shield tunnel achieves penetration

The moment of the steepest interval left line tunnel in the Deyang section
The total length of the tunnel is 1197.6 meters
The vertical slope can reach maximum 28‰
equivalent to each kilometer of digging forward
Altitude drops by 28 meters
Faced with the challenges of large slope construction
Construction team adopts
The method of "Stratigraphic reinforcement + precision excavation + synchronous grouting"
By advance the perimeter of the pipeline
Grouting and reinforcement in the area below the overpass
and during excavation
Real-time adjustment of shield angle and direction
Finally control the shield accuracy to the millimeter level
Realizes safe and efficient tunneling

Shield structure pipe is being transported to the assembly position
At present, there are 19 shield machines synchronous operations in the Chengde Line
27200 meters
60.7%
6 shield tunnelsSuccessfully completed
where, The longest shield interval in the entire line
Total length reaches 4101.5 meters
The interval between Wenmiao Square Station and Deyang North Station
New progress has also been made recently
This interval has been dug 2683 meters and reached the intermediate air well
The next step will continue toward the direction of the Confucian Temple Square Station
Push the rest

Shield structure tube sheet assembly
8-station main structure capped
The first station has completed structural construction

Wuzhou Plaza Station is completed first
On the basis of the capping of the main structure
The construction of the auxiliary structure has been successfully completed recently
Become the first station on the Chengde Line to complete all structural construction

The Wuzhou Plaza Station has fully completed the structural construction
At present, the Chengde Line is in the 15-station stations The main structure capping has been completed stations
7 stations have entered the Affiliated structure construction stage
4 stations are underway
Project diagram, for reference only
Chengde Line is the urbanization of Chengde, Mei and Zizhou
Important projects in the backbone commuting network
The project starts from Weijianian Station on Chengdu Metro Line 1
Stops at Deyang North Station in Deyang City
Total length 70.87 kilometers
A total of 15 stations
Promotion will be carried out after the project is completed
Chengdu and Deyang enter the era of "Rail-city"
Promote between Chengdu and Germany
Efficient gathering of industries, population and various production factors
To enhance the core energy level of Chengdu metropolitan area
Promote the construction of the Chengdu-Chongqing Twin Cities Economic Circle and
The urban development of Chengdu, De, Mei and Zizhou is of great significance
