The total construction period of the reconstruction project from Chongqing station to Jiangjin section of Chengdu Chongqing railway is 3 years
On the afternoon of 18th, the reconstruction project of Chongqing station Jiangjin section of Chengdu Chongqing railway was officially launched. In the next three years, on the basis of retaining the existing line as a whole, the railway section will carry out the expansion and reconstruction of the additional second line to form double line transportation. There are 10 existing stations in Chongqing Jiangjin section and 13 stations in total after the construction of the second line The section from Chongqing station to Jiangjin of
Chengdu Chongqing railway is a single track railway with a length of 65.08km and 10 existing stations. The line was completed and opened to traffic in 1952. As the first railway independently built in New China, it has been in operation for nearly 70 years. There are many engineering diseases such as mud pouring from foundation bed, slope sliding of embankment, exposed reinforcement corrosion of bridge reinforcement, deformation and dislocation cracking of culvert, weathering and cracking of tunnel lining, etc., with high maintenance cost and high transportation safety pressure
with the planning and construction of "meter" type high-speed railway in Chongqing, the gradual improvement of passenger transport function of Chongqing railway hub and the gradual outward movement of freight distribution, the function of trunk line from Chongqing station to Jiangjin section of Chengdu Chongqing railway is gradually weakened, and its role in passenger and freight transport is gradually reduced
according to the principle of "overall planning and implementation by sections", Chongqing station Jiangjin section will be transformed into an urban railway, which is planned to extend northward to connect Chongqing north station and Jiangbei Airport, forming an urban railway running through the city's main urban area for about 130 kilometers from north to south, realizing the rational utilization of the existing railway, improving the railway public transport network, strengthening the radiation drive of the main city to the surrounding areas, and alleviating the impact Ground traffic pressure in the core area of the main city After the transformation of
, 13 stations will be set up to seamlessly change into rail transit and urban express railway
. According to the introduction, the reconstruction 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 capacity expansion and reconstruction of the additional second line will be carried out to form double line transportation, maximize the preservation of historical status and reduce project investment The
line is 60.869km long, the proportion of bridges and tunnels is 17.01%, double track railway, and the railway grade is grade I. The design speed target value is 80km / h, and the local speed limit in special difficult sections. After the transformation, the passenger transport adopts the mixed operation of station stop train, one station direct (large station staggered stop) train and general passenger train, and the operation time of the whole line is about 60 minutes, so as to realize the fast commuting demand between urban groups and the slow tourism and sightseeing function along the river. The freight transportation adopts the combination of direct train and detachable train There are 10 existing stations in Chongqing Jiangjin section of
, and a total of 13 stations will be set after the second line is added. Including: Chongqing station, Egongyan, Huangjueping, Yidu ancient town, jizixi, yuyuzui, funiuxi, Xiaonanhai, tongtangyi, Xipeng, huangn, Shengquan, Jiangjin station, two Dadukou and Jinao stations are reserved
railway station is connected with urban rail transit and urban rail express to realize the integrated development of "three railways", including seamless transfer between Chongqing station and planned rail transit lines 12 and 18, urban rail express lines 26 and 27, seamless transfer between Huangjueping station and rail transit line 18, seamless transfer between Yidu ancient Town station and rail transit line 12, and seamless transfer between jiazixi station and rail transit line 1 Seamless transfer of line 8, etc It is understood that the reconstruction project of Chongqing railway station Jiangjin section of Chengdu Chongqing railway, as an urban railway in the main urban area of Chongqing, can give full play to the role of connecting the preceding and the following after completion. In the future, it will continue to extend northward to connect Chongqing north railway station, through Chongqing north railway station and Chongqing station The hub can be seamlessly connected with national trunk railways such as Chongqing Hunan, Chongqing Han or Chongqing Wancheng intercity railway, and can also be connected with huangmaoping branch line and airport branch line for operation
at the same time, the urban railway running through the north and south of the main city is an important north-south fast passenger transport channel. Together with the urban road and urban rail transit in the main city area, it forms the comprehensive transportation system of urban traffic in the main city area, which plays an important role in expanding the effective supply of traffic and alleviating the ground traffic pressure in the main city area A 6031 a 6031 in addition, a number of scenic spots such as Longfeng temple, Railway Museum, Chongqing Iron and Steel Industry Museum, ancient town of Masangxi, ancient town of tongtangyi are connected in the section from Chongqing station to Jiangjin, which can be described as "one stop one scenic spot, one station with characteristics". It will become a light for Tourism along the river, enhance the landscape value of mountains and waters, highlight the characteristics of Chongqing, make tourists see mountains, see water and recall nostalgia And enjoy "slow life" and indulge in "slow time".
