In recent years, with the continuous development of national economy of China, the economic exchange with surrounding countries is more and more frequent, and the external trade amount is continuously increased. The international railway is used as the most important channel for connecting China with surrounding countries, and plays an increasingly important role in accelerating the trade development among the countries and strengthening the economic construction of marginal areas. In recent years, the traffic volume of railway port stations in China has been greatly developed, and a plurality of main port stations are subjected to large-scale reconstruction and extension projects or are under way to adapt to the increasing demand of passenger and freight volume. In order to meet the continuous demand of the economic development of China on raw materials and strengthen the economic cooperation with surrounding countries, some new international railways are already brought into the planning or are carrying out early research work.
Railroad crossings are typically located near borders of different countries or regions. According to international practice, each country has a port station (reloading station) in its own country, and each takes charge of reloading of imported goods (i.e., peer-to-peer reloading). Therefore, railway lines with respective track gauges are laid between the two port shore stations, trains with different track gauges in the port shore stations enter corresponding yards of the opposite port shore stations through the lines with the same track gauges, and reloading operation is completed. The standard arrangement form of the lines between port and shore stations is double-line parallel, the rail sleeving is to make two lines with different track gauges collinear, the lines with different track gauges are mutually nested, and a sleeper and a roadbed are shared.
In the aspect of the application of the rail-sleeved railway sleeper, a common steel rail is used for rail-sleeved lines with certain track gauges, the common steel rail is used, the top surfaces of the two kinds of track gauge lines are kept at the same height, the sleeper design belongs to the variable cross section design along the length direction in order to adapt to the characteristic of track bed counter force, and the condition is difficult to realize on the sleeper process.
