67 year old Chengdu Chongqing railway implements reconstruction of additional second line from Chongqing station to Jiangjin section
On November 18, the reconstruction project of Chongqing station Jiangjin section of Chengdu Chongqing railway was officially started. On the basis of retaining the existing line as a whole, the expansion and reconstruction of the additional second line will be carried out to form double line transportation The reconstruction project of
is in the charge of the headquarters of the east ring line of Chongqing railway terminal. It is understood that the construction of the additional second line will become a light for Tourism along the river and open the railway transit train. The line is planned to be completed and open to traffic by the end of 2022, and it will take about 1 hour by train from Jiangjin to Caiyuanba, Yuzhong District Why does
need to be transformed The
Chengdu Chongqing railway was completed and opened to traffic in 1952, which is the first railway built after the founding of new China
it runs from Chengdu station to the East, passes through Ziyang, Zizhong and Neijiang River, enters Yongchuan, Chongqing, and reaches Chongqing station along the North Bank of the Yangtze River, with a total length of 504km
"this railway is a single track railway, which has been in operation for nearly 70 years. At present, there are many diseases." The headquarters of East Ring Road of Chongqing railway terminal introduced that at present, there are many engineering diseases along the Chengdu Chongqing railway, such as mud pouring from subgrade bed, slope sliding of embankment, corrosion of exposed reinforcement of bridge, deformation and dislocation cracking of culvert, weathering and cracking of tunnel lining, etc., with high maintenance cost and high transportation safety pressure
is not only that, with the planning and construction of "meter" shaped high-speed railway network in Chongqing, the passenger transport function of Chongqing railway hub is gradually improved and the freight distribution is gradually moved out, the function of trunk line from Chongqing station to Jiangjin section of Chengdu Chongqing railway is gradually weakened. At present, there are only more than 10 pairs of trains departing from Chongqing station, and the role in passenger and freight transportation is gradually reduced
"in order to extend the service life of Chongqing station Jiangjin section of Chengdu Chongqing railway, continue the railway transportation function, inherit the context, activate and utilize the existing resources, it is necessary to carry out disease treatment on the existing railway and eliminate the potential safety hazards." The head of heavy rail group said According to
, the reconstruction period is three years, with an investment of 9.38 billion yuan, and the urban railway with rapid rail transit function will be built in a relatively short time There will be 13 stations in the whole line of
, and the newly built station will wait at the platform. There is no special waiting room for the transformation project of Chongqing station Jiangjin section of
Chengdu Chongqing railway starts from Chongqing station of Yuzhong District, passes through Jiulongpo District and Dadukou District to the southwest and ends at Jiangjin station of Jiangjin district. In the reconstruction scheme, on the basis of retaining the existing line as a whole, the expansion and reconstruction of the additional second line will be carried out to form double line transportation, maximize the historical status and reduce the project investment Before the reconstruction of
, the existing line is about 65km long, and the transformation line of Kowloon Peninsula section adopts the case of cutting off the bend to take the direct access to the local area; after the reconstruction, the line is 60.9km long, the bridge tunnel ratio is about 17%, the design speed of the double line is 80km per hour, and the local speed limit of the special section is limited In terms of the establishment of
station, there are 10 existing stations from Chongqing station to Jiangjin section of Chengdu Chongqing railway. After the construction of the second line, there are 13 stations in total: Chongqing station, Egongyan station, Huangjueping station, Yidu ancient town, jiazixi station, yuyuyuzui station, funiuxi station, Xiaonanhai station, tongtankyi station, Xipeng station, huangn station, Shengquan station and Jiangjin station. Two stations, Dadukou station and Jinao station, are reserved
in order to facilitate the rapid boarding of citizens, the new station is designed according to the platform waiting mode, with the station hall layer and platform layer, without waiting room, etc. Generally speaking, it is designed according to the current subway mode, and the waiting room is no longer designed separately According to
, after the reconstruction of Chongqing Jiangjin section of Chengdu Chongqing railway, it will be built into a tourist line A 6031 a 6031 Chongqing station Jiangjin section is connected with a number of scenic spots such as Longfeng temple, Railway Museum, Chongqing Industrial Museum, Yidu ancient town, yuyuzui humanities and art Peninsula, tongtangyi ancient town, tongtangyi Catholic Church, etc
"Chengdu Chongqing railway has condensed the memory of several generations of Sichuan and Chongqing people, and we will transform it according to the concept of" protecting and inheriting history " According to relevant personnel from the headquarters of East ring line of Chongqing railway hub, the existing railway reconstruction project only deals with the defects of subgrade, bridge and tunnel according to the principle of "repairing the old as the old", so as to retain the original features of Chengdu Chongqing railway to the maximum extent
to this end, the additional second line will be built into a tourism view light along the river. According to the construction of "one station, one scenery, one station with characteristics", it will highlight the characteristics of Chongqing, so that tourists can see the mountains, see the water, and remember the homesickness According to the plan, the additional second line of Chengdu Chongqing railway will be transformed into urban railway, and the transportation capacity will be increased by three times when the EMU train is operated The newly built station of
will be effectively connected with rail transit, urban rail express, Chongqing north railway station and Jiangbei Airport to build a "three railway" integration demonstration line and realize "zero transfer" According to
, Chongqing railway station will seamlessly transfer with the rail transit line 18 under construction, the planned rail transit line 12 and the urban rail express line 26 and 27. For example, Huangjueping station and jiazixi station will transfer seamlessly with rail transit line 18, Yidu ancient town station and rail transit line 12, etc
"the stations set along the river are integrated with the design and construction of tracks, buses, taxis, network car hailing and social vehicle parking lot, forming a seamless transfer hub node." Heavy rail group said
in order to facilitate the travel of citizens, the reformed passenger train will adopt the mixed operation mode of station stop train, one station direct (large station staggered stop) train and general passenger train to realize the fast commuting demand between urban groups and the function of slow Tourism along the river. The freight shall be transported by direct train and uncoupling train
in the future, the Chongqing station Jiangjin section of Chengdu Chongqing railway will also be seamlessly connected with Chongqing Hunan, Chongqing Han and other national trunk railways and Chongqing Wancheng intercity railway, and will be connected with huangmaoping branch line and airport branch line for operation, so as to realize the seamless connection of railway, rail transit and high-speed railway, and greatly relieve the ground traffic pressure in the core area of the main city.
