Brief introduction of Chengdu-Guiyang high-speed railway

In the future, the cities along the route will develop the urban agglomeration in western Sichuan Plain with Chengdu as the center, Leshan-Wutongqiao-Qianwei-Yibin as the development axis, and Guiyang as the center to develop the Mianle urban agglomeration, thus forming the Cheng Gui Economic Corridor through coordinated urban and rural development.

1. Chengdu-Guiyang railway (Leshan-Guiyang section) has a total length of 520.325 kilometers (main line is 509.053 kilometers), and the investment of the whole line is estimated to be 7 199862.2 1 10,000 yuan. Among them, the static investment is 62 10589. 1348 yuan (technical and economic index 122002800 yuan/main line kilometer); The loan interest during the construction period was 4.23 billion yuan; The working capital of the Foundation is 61070,000 yuan; The procurement cost of EMU is 5,598.4 million yuan. According to the opinions of the project proposal and the spirit of the minutes of the provincial meeting, this project is jointly built by the Ministry of Railways, Sichuan Province, Yunnan Province and Guizhou Province. The construction fund is: 50% of the domestic bank loan, and the provinces are responsible for the land acquisition and demolition work and expenses according to law, and the expenses are recognized as local investment by all parties; The rest of the funds are funded by the Ministry of Railways, using railway construction funds and railway enterprises' own funds.

2. Construction scheme: This line will be built as a passenger dedicated line, in which Leshan-Guiyang section of Chengdu-Guiyang Railway will be built as a one-time double line, and Mianle Intercity Railway from Chengdu to Leshan will be built as a long-term branch line.

3. There are 13 stations on the whole line (excluding Leshan Station, Guiyang East Station and Guiyang North Station), of which Baiyun is the contact station. According to the published EIA content, the geological environment conditions in the evaluation area are complex, the proposed project is an important project, and the risk assessment level of geological disasters is Grade I ... The newly requisitioned land in the whole line 18680.5 mu, with an average of 35.90 mu per line kilometer; 26,679.5 mu of temporary land; The average line kilometer is 5 1.27 mu. Bridges and tunnels account for 78.6% of the whole line, including 365 bridges, accounting for 15 1 km, accounting for 29.69% of the total length of the line; 0/83 tunnels/KLOC-are all double-line single-hole tunnels with a total length of 247 kilometers, accounting for 49.50% of the total length of the line. The longest tunnel in the whole line is Shangheba Tunnel, with a total length of 13km. In addition, Yaojiaping Tunnel and Dachongzi Tunnel are also about 8km and 7km long respectively.

With the increase of bridges and tunnels, it will naturally increase the difficulty of line design and construction. In particular, Jinsha River Bridge, Shangheba Tunnel, Nanguanghe Double-track Bridge, Xiangbahe Bridge, Diaonanhe Bridge, Luojiahe Bridge and Xixihe Bridge are all difficult projects, which are a great test for design and construction. In addition, it is the first Yachi River Bridge in the world with similar bridge construction technology.

In terms of environmental protection, the total investment will reach 1 677,654,38+0,000 yuan, of which the investment in noise reduction project will reach 1 654,38+0,532 million yuan, which will minimize the environmental impact after opening to traffic. The Environmental Impact Report on the Project Change of Leshan-Guiyang Section of Chengdu-Guiyang Railway has changed the scenery of Yuexi River in pingshan county from the perspective of environmental protection. At the same time, in order to protect the habitat of rare fish, the design of bridge piers across the river will no longer be adopted in the construction of Chengdu-Guiyang Railway, and other bridge piers across Minjiang River and Jinsha River will no longer wade except during the construction period. Scope: involving 7 districts and counties, there will be 4 stations.

Chengdu-Guiyang Railway accounts for one third of the total length in Yibin, and five stations will be set up in Nixi Town, pingshan county, Yibin City, Changning County, Yibin County and Xingwen County. According to the information released by Yibin City Land and Resources Bureau, the land of Yibin section of Chengdu-Guiyang Railway involves 7 counties (districts), 27 towns, 1 15 villages and 282 communities (groups), and will cover an area of 492.54 hectares. Among them, there are 23.88 hectares of state-owned land and 468.66 hectares of collective land. Before the construction of Chengdu-Guiyang Railway, the land needed for the project has been used first, and all the relevant procedures required by Yibin have been completed. It is necessary to do a good job in the preparation and implementation of land acquisition and demolition of Chengdu-Guiyang Railway to ensure the construction land of Chengdu-Guiyang Railway. In addition to doing a good job in ensuring the construction land for the project, he also proposed that the governments of all districts and counties in Yibin and the municipal finance should also do a good job in raising funds involved in the Chengdu-Guizhou Railway in advance. At the same time, fully cooperate with Chengdu-Guiyang Railway Company and the construction unit to do a good job in construction coordination to ensure the smooth construction of Chengdu-Guiyang Railway. Change: The new scheme avoids the scenic spot of Pingshan Yuexi River.

The Ministry of Environmental Protection released the environmental impact report of the engineering change of Leshan-Guiyang section of Chengdu-Guiyang railway. Eight 248-kilometer railway lines from Chengdu to Guiyang have been changed, and three in Sichuan Province. Yibin mainly involves the rerouting of Yuexi reach in pingshan county. It is reported that Pingshan Station was originally planned to be set up in Yuexi River Scenic Area. However, in order to meet the requirements of avoiding scenic spots, combined with the planning of Pingshan County, the current plan bypasses the scenic spots of Yuexi River. In addition, it is understood that the Chengdu-Guiyang Railway will cross the core area and buffer zone of the national nature reserve for rare and endemic fish in the upper reaches of the Yangtze River in Yibin and Weixin and Zhenxiong of Yunnan 1 1 times. Among them, in Yibin City, it mainly passes through the buffer zone of the reserve through the Yuexi estuary section, and the Minjiang Caiba passes through the buffer zone of the reserve. Progress: The project entered the bidding stage on 20 13. In order to promote the Yibin section of Chengdu-Guiyang Railway, in May 20 13, Yibin also established the "Yibin Cheng Gui (Yibin Section) Engineering Command", with Chen Zheng, member of the Standing Committee of Yibin Municipal Committee and secretary of the Municipal Political and Legal Committee, as the commander, to organize and carry out the preliminary work of various projects. Before the start of Chengdu-Guiyang Railway, the land use required by the project and the relevant procedures for modifying the EIA provided by Yibin have all been completed. At the symposium between Yibin and Chenggui Railway Company, Zhang Guoli, Chairman and General Manager of Chenggui Railway Company, revealed that the project has entered the bidding stage. It is understood that the "mountain high-speed rail" Chengdu-Guizhou railway, which runs through Yunnan, Guizhou and Sichuan provinces, will be opened simultaneously in June 5438+February. The whole railway construction project is expected to be completed in 20 19. By then, it will only take 1 hour from Chengdu to Yibin, and this high-speed rail will also become the fastest passage for Sichuan Province to go south to Sichuan.
