Introduction of the Dallailong Railway Line?

Dalailong Railway starts from Weifang Dajiawa Station of Yiyang Railway in the west, ends at Haihua, Shouguang, Hanting, Changyi, Pingdu, Laizhou and Zhaoyuan in the east, and reaches Longkou City, Yantai, with a total length of 175km. Construction started in May, 1999, and the whole line was put into operation in 2005 with a total investment of 1 148. There are Dajiawa Station, Hanting Station, Changyi Station, Shahe Station, Laizhou Station, Zhu Qiao Station, Zhaoyuan Station, Longkou Station, Longkou North Station and Longkou Port Station along the line. In 20 10, the annual traffic volume of Dalailong Railway exceeded 8.3 million tons, and in 2010, it exceeded10 million tons. At present, the line reconstruction is in progress.

Significance of architecture

Dalailong Railway Line is one of the important plans in the Minutes of Talks of Shandong Provincial Government of the Ministry of Railways on Accelerating Shandong Railway Construction, and it is an integral part of the coastal passage around Bohai Bay. It is the "one horizontal" in the "four vertical and four horizontal" backbone railway network construction plan proposed by Shandong Provincial Government, and it is an important part of the southern trunk line of "Bohai Railway Network" from Delong to Yantai. Dalailong Railway, Longyan Railway, which has already started construction, and Huangda Railway, which is about to start construction, together constitute the great corridor of the northern coastal railway in Shandong Province and become the southern trunk line of the "Bohai Rim Railway Network". It is of great significance to optimize and improve the layout of the national railway network and promote the economic development of the northern coastal areas of Shandong Province and the development of the Yellow River Delta. The railway passes through Weifang Hanting District, Changyi City, Qingdao pingdu city City, Laizhou City, Yantai Zhaoyuan City, Longkou City and other economically developed areas of Jiaodong Peninsula, with dense ports along the route, rich mineral resources and industrial and agricultural products, and a good industrial and agricultural production foundation. The total throughput of Weifang Port, Laizhou Port and Longkou Port has reached tens of millions of tons, especially Longkou Port, which ranks first among local ports in China and has a good deep-water wharf, which can provide reliable guarantee for coal transportation after the opening of Huangda Railway.

Economic traffic volume

According to the new economic benefit evaluation results of 200 1 by the first railway survey and design institute, under the new situation of the integration of Huangda Railway and Deda Railway, the initial freight volume of Dalailong Railway is 6.5 million tons, the recent freight volume is 20 million tons, and the forward freight volume is 60 million tons, which will gradually show social and economic benefits. As of June 28th, 2008, 165438+ Shandong Dalailong Railway has exceeded 3 million tons, which is three times that of the same period of last year, and achieved the annual transportation production task in 2008.

By the end of 201110218, the freight volume of Dallailong Railway Company reached 10009 million tons, completing the annual transportation task of10009 million tons 59 days ahead of schedule, and stepping into the annual transportation volume of over 10 million tons.

subject of investment

Dalailong Railway Line is a project supported by 65438-0998 national debt funds, and it is also a key construction project in our province. Shandong Dalailong Railway Co., Ltd., the construction unit, was established with the approval of the government in February 1998. The company was established by seven shareholders, including Shandong Local Railway Bureau, Yantai Local Railway Preparation Office, China Railway Construction Investment Company, Weifang Local Railway Bureau, Shandong International Trust and Investment Co., Ltd., pingdu city Urban Construction Investment Company and Jinan Railway Bureau, and was approved by Shandong Administration for Industry and Commerce in June, 20 14. 1999. The company shall set up a board of directors, a board of supervisors, a general manager and other institutions to be responsible for the organization, construction, operation and management of railways. Xu Junfeng, director of Shandong Local Railway Bureau, is the company's chairman and party secretary, and Wang Shanchun is the company's general manager and deputy secretary of the party committee.

Line reconstruction

It is understood that the Dalailong railway line was implemented at the beginning of construction on the principle of "first in and then out", with low standards and insufficient supporting facilities. Since its opening, potential problems have gradually emerged. The overall standard of track, subgrade and bridge and culvert of Dalailong Railway is low, and some subgrade diseases such as subgrade sinking, boiling and slurry leakage exist. The backwardness of railway construction itself and the imperfection of supporting facilities are the driving forces for the transformation and upgrading of Dalailong Railway.

In addition, the functional positioning of Dalailong Railway in the road network also forced the transformation and upgrading of Dalailong Railway. Dalailong Railway is located in the middle of Delongyan Railway Passage, with the west end connected with Deda Railway and the east end connected with Longyan Railway. Both the German-Dalian Railway and Longyan Railway are national railways I-class, with electrification design standards and functional orientation of both passenger and freight. The Dalailong Railway in the middle section is a first-class pure freight railway of subway driven by internal combustion engine, with a design speed of120km, and its technical standard is lower than that of Deda Railway and Longyan Railway.

If the electrification transformation and other technical upgrading are not completed before the opening of the Deda Railway and Longyan Railway, the whole Longyan Railway will be "blocked" in the middle, which will seriously affect the function of the whole railway. In order to build a large corridor of Delongyan Railway with unified technical standards and high efficiency, in March of 20 10, the Ministry of Railways and Shandong Province started the upgrading and capacity expansion project of Dalailong Railway according to the unified technical standards of Delongyan Railway.

It is understood that the reconstruction of the Dalailong railway line is through the addition of a second line and the electrification of the existing line. Railway design speed160km, with 200km reserved. By then, Dalailong Railway will realize the situation of mixed passenger and freight running, and people in Zhaoyuan, Longkou and Laizhou in Yantai will be able to travel by train.

In addition, the reconstructed Dalailong Railway Line will have all the functions of ordinary railways, and will also be endowed with the functions of intercity railways in a certain period of time.
