Project design change
Huang Wu Intercity Railway
Huang Wu Metro adopts Type III track slab with independent intellectual property rights in China. The original design speed was 300 kilometers per hour, and then it was reduced to 250 kilometers. The train control system was changed from CTCS 3 to CTCS 2.
Huangshi-Jiujiang section
The project proposal was approved on July 20 10. The main technical standards of this project are: passenger dedicated line, double track, speed target value above 200 km/h, maximum gradient of 20‰, minimum curve radius of 5000 m, effective length of arrival and departure lines of 650 m, electric traction, automatic control and centralized comprehensive dispatching. The total length of the line is 66km, and the bridge-tunnel ratio is 69%. The total investment of the project is estimated to be 7.7 billion yuan, and the project duration is 3 years.
The main technical standards of this project approved in the feasibility study report of October 2011June are the same as those approved in the project proposal of July 20 10. The total length of the line is 67.9 kilometers, with three stations: Baisha South, Yangxin and LAM Raymond, and the bridge-tunnel ratio is 72.5438+0%. Rebuild the existing Wujiu Railway by 4.6 kilometers, and expand Wuhan EMU at the same time. The estimated total investment of the project is 8.665438 billion yuan, and the project duration is 3 years.
From 20 12 to 10, the former Ministry of Railways and Hubei Province jointly reviewed the feasibility study report (revised draft) again and formed a review opinion. According to the review opinions of 20 12 and 10, the following contents have been optimized and adjusted in this preliminary design:
(1) Speed target is adjusted to 250km/h, ballastless track is changed to ballasted track, train control system is changed from CTCS-3 to CTCS-2, and minimum curve radius and line spacing are adjusted accordingly.
(2) Optimize the parallel station scheme of Yangxin Station: optimize and adjust the passenger dedicated line from the same side of the station building to the new one on the opposite side of the station building, and only transform the outermost 1 track of the existing general-speed parking lot of Yangxin Station without transforming the existing Wujiu Railway. Build a new platform for passengers only on the right side of the general speed field, so that Yangxin Station can meet the standard of three 1 1 lines.
(3) The feasibility study approved the construction of 15 parking line in the reserved parking place of Wuhan EMU. At present, the parking lot reserved for Wuhan EMU has been included in the first-class change of Zheng Wu Passenger Dedicated Line and is under construction. Wuhan EMU does not have the capacity expansion conditions. On February 20 12, our group company made a special study on the merger scheme of the newly-built Wuchang South EMU and the Automobile Depot in Wu Nan Freight Yard. Because this scheme involves the comprehensive transformation of Wu Nan freight yard and some existing Beijing-Guangzhou uplink lines, the project quantity is large and the scope is wide. This time, only the scheme research was done, and the relevant investment was not estimated, nor was it included in this project.
Main technical standards after design change:
(1) Railway grade: dedicated passenger line;
(2) Number of main lines: double lines;
(3) Design and operation speed: 250 km/h;
(4) Main line spacing: 4.6m；;
(5) Minimum curve radius: 3500m；;
(6) Maximum gradient: 20 ‰;
(7) Track type: Ballasted track (except long tunnel);
(8) Train control system: CTCS-2;
(9) Traction type: electric power;
(10) Locomotive type: EMU;
(1 1) Effective length of arrival and departure lines: 650m;
(12) Train operation mode: automatic control;
(13) Traffic command mode: comprehensive dispatching is centralized.
For Jiangxi, the Wujiu Passenger Dedicated Line not only strengthens the communication between Jiangxi and Hubei provinces, but more importantly, this line will be conducive to the formation of a passenger dedicated line from Nanchang to Beijing.
201212/April February, the Ministry of Railways announced that the Beijing-Guangzhou high-speed railway was completed on February 2 6, 2006, becoming the longest high-speed railway in the world, with the shortest time of 7 hours and 59 minutes. After the opening of the Beijing-Guangzhou high-speed railway, there will be two kinds of seats, D-prefix train and G-prefix train, in which the D-prefix train has a speed of 250 kilometers per hour and the G-prefix train has a speed of 300 kilometers per hour.
Nanchang and Wuhan are only connected by ordinary railways. The construction of Wujiu Passenger Dedicated Line will promote the connection of Nanchang-Jiujiang (Changjiu Intercity Railway)-Huangshi-Wuhan (Wujiu Passenger Dedicated Line), and the high-speed railway will go directly from Nanchang to Beijing.
