Study On Railway Marshalling Yardsreconstruction And Extension And Construction Scheme

With the speeding step of railway construction and railway network scale unceasing expansion, the railway transportation ability have been greatly improved, especially the line capacity has been greatly improved, which brings the lag hub construction or renovation, especially the station, marshalling station construction or renovation construction lags behind the lines, the formation of point, line capacity does not match. Especially plays a very important role in the road network capacity of marshalling station, marshalling station restricts the hub through the ability to a certain extent, the overall. In order to improve the marshalling station capacity, the domestic, abroad have conducted a study, the formation of some ideas and methods. As the railway construction headquarters of project management organization, is the whole process of project construction and operation management, and are inseparable, is very important in project initiation, execution process plays a role, can actively study the design and construction scheme of the project, determine the design scheme and construction scheme of scientific, feasible. Therefore, the study and formulation of marshalling station expansion and construction scheme for the smooth implementation of the project, the construction of economic efficiency, promotion of marshalling station capacity, is very necessary and significant role to realize supporting point and line capacity.This paper selects Xiangyang North Marshalling Station as an example, through an in-depth analysis on the present situation and the ability of Xiangyang North Marshalling Station, focus on traffic analysis, a hinge of linking line technology standard line and in the hub of transportation organization analysis, analysis of the existing, found in Xiangyang North Marshalling Station in freight train imbalance to hair, train the station ability is insufficient; the adjacent line technical standards are not unified, aggravating the station tight capacity situation; the rapid growth of station operation quantity, station type is difficult to adapt to the three aspects of increasing the amount of hub operations and other issues. The research results of domestic similar problems of marshalling station based on, outside, put forward for the Xiangyang North Marshalling train of thought and method of reconstruction of station, determined based on existing one-way three level Four station type, additional uplink system, the formation of two-way three grades and six yards, the ability to meet the needs of. At the same time, the design scheme based on existing lines, combined with the characteristics of both, construction and transportation, on the premise of traffic safety to ensure smooth transportation, under the overall scheme, research has identified seven phases of construction. The main research results are as follows:1.Of the domestic and foreign related problem of marshalling station, studied the concept, understanding of the different development of domestic, outside the marshalling station; seriously study the ideas and methods to solve the problem of domestic, inadequate capacity of marshalling station marshalling station renovation construction, laid the foundation for the research of this paper.2.The use of project management knowledge of Xiangyang North Marshalling Station building situation of engineering project management system uplink analysis, find out the influence factors of Xiangyang North Marshalling Station additional uplink system project design and construction scheme, provide a basis for further study to determine the design and construction scheme.3.Pairs of Xiangyang North Marshalling Station both equipment and transportation capacity analysis, research trend prediction of traffic volume on the economic development of Xiangyang City area brings, the status and role of the combination of Xiangyang hub in the road network, as well as the main railway hub of cohesion and capacity needs comprehensive consideration of project stakeholders, relates to the parties concerned, puts forward revamping scheme of additional uplink system of Xiangyang North Marshalling station.4.Transformation of the construction scheme of the understanding and research of the marshalling station, the analysis of the relationship between transportation and construction, considering the construction phase of the project stakeholders to parties concerned, investment, safety, quality, time limit for a project such as the goal, in the premise of safety traffic to ensure smooth transportation, the research, to determine the overall scheme of seven stages of construction, use to guide the preparation of construction unit to implement the construction scheme, construction and transportation to achieve a win-win situation.
