2065438+March 2002 National Twelfth Five-Year Comprehensive Transportation System Planning IV. The main tasks of the column "Express Railway" include "Huai Shao Heng". Therefore, Huaishaoheng Railway is the Huaishaoheng Express Railway.
Name problem: National planning belongs to fast railway. Many medium-sized railways in the northeast use the name of express railway, while many people in the south misunderstand express railway as high-speed railway. Hunan's Huaishaoheng Railway and other express railways rarely use the name of express railway on the Internet. Only Yuchangxia Railway is named Yuchangxia Express Railway. In addition, the official media of the capacity expansion and reconstruction projects of Changbai Railway and Chongqing-Guizhou Railway mostly refer to Changbai Express Railway and Chongqing-Guizhou Express Railway, while similar projects of Loushao Railway and Jinwen Railway rarely use such names, only adding a new word. Including the main line and auxiliary line, Huaishaoheng Railway needs to excavate 465 tunnels and 438+0 tunnels and erect 243 bridges, and the bridge-tunnel ratio accounts for 57% of the total length of the line. The main line of the whole line is designed with 265,438+08 large and medium-sized bridges, 90.765,438+0km, and 40 tunnels, 84.70km.. The total length of bridge and tunnel on the main line is 175.4 1 km, and the bridge-tunnel ratio is 55.08%, which is a typical mountainous and hilly railway.
Key Bridge and Tunnel Project of Huai-Shao-Heng Railway 1) Tunnel:
Liangshan (Huangyan) tunnel17037m, Xiangjiashan tunnel 4014m, Baishiwan tunnel 3788m and Jianfengshan tunnel 6414m.
Fengmuchong Tunnel is 2873 meters, and Nanxuefeng Mountain Tunnel is 9549 meters. Lashujiao Tunnel is 2466m, Cangqianling Tunnel is 80 10m, Yanyuan 'an Tunnel is 5320m, Tianlongshan Tunnel 165 1m, Luojia Tunnel 1044m, Xiangfengling Tunnel is 2290m, and Chazishan Tunnel/kloc-0. There are four tunnels, namely Liangshan Tunnel (Huangyan Tunnel), Jianfengshan Tunnel, Nanxuefengshan Tunnel and Cangqianling Tunnel. The former 12 is located between Huaihua South Station and Shaoyang, and the latter two are located between Shaodong and Hengyang.
2) Bridges:
Huaihua City: 887m of Shui Yuan Bridge in Anjiang Town (lots of pictures of the construction site: Latest Development of Huaishaoheng Railway (Anjiang Railway Construction) 1 Contract), Shaoyang City: 437m of Jiangkou Bridge in Jiangkou Town, Dongkou County, Xiamijiawan Bridge1902m, Huangnijiang Bridge1kloc-0. Fujiadu Bridge is 922 meters, Chenshui Bridge is 706 meters, Baizhuhe Bridge is 862 meters, Shuangjiang Reservoir 1 No.1 Bridge 1838 meters, Shuangjiang Reservoir No.2 Bridge is 2 123 meters, Zishui Bridge is 7 14 meters, Shaoshui River Bridge is 2533 meters.
It is 545m across Shaoyang East Link Bridge of Shanghai-Kunming Expressway, 868m across expressway Bridge, 2nd Shaoshui River Bridge1210m, 4089m across Rui-expressway Bridge, existing Loushao Line Bridge1437m across Niuanling Bridge1044m across Royal River. The jurisdiction of Hengyang City: Zhengshui 1No. Bridge182m, Luojiatou Bridge 1347m, Wuzutang Bridge 855m, Liucitang Bridge 1248m, Louheng Expressway Bridge 675m and Quantang Bridge/Kloc. It spans 2,808 meters across Beijing-Hong Kong-Macao Expressway Bridge, 8 15 meters across Lianhuatang Expressway Bridge, 2,384 meters across Nanyue Expressway Bridge, 0/022 meters across Xiangjiang Expressway Bridge and 604 meters across Evergrande Expressway Bridge. The total construction period of Huaishaoheng Railway is 54 months to 4.5 years. Overall construction began at the end of June 20 14, and it is planned to be completed at the end of 20 18.
The section from Shaoyang Station to Shaodong Station is parallel to the * * channel of Loushao Railway. 20 12 in may, the Ministry of railways and Hunan province approved the 34km parallel section of shaoyang-shaodong fourth line to be started ahead of schedule. (3) Investment estimation and fund raising
The estimated total investment of the project is 32.43 billion yuan, including 3,654.38+0 billion yuan for engineering investment and 654.38+0.4 billion yuan for vehicle purchase. The sources of funds are: the capital of the project accounts for 50% of the total investment, of which: 3.29 billion yuan is allocated in the central budget by our commission and 2.47 billion yuan is allocated by the Ministry of Transport for vehicle purchase tax; Hunan provincial government is responsible for raising 4.86 billion yuan; The remaining 5.6 billion yuan was used by China Railway Corporation for railway construction funds and railway construction bonds. Funds other than capital are financed by loans from domestic banks such as China National Development Bank. Hunan Province undertakes the land acquisition and demolition work, and the expenses can be offset by local funds after being approved by both parties. China Railway Corporation and Hunan * * * jointly set up a joint venture company to be responsible for construction management as a project legal person. 〕
