Field of the Invention The present invention relates to improvements in railway history and construction methods thereof, and more particularly, to a railway history and a construction method thereof that can be suitably applied to the construction of a railway track passing over a historical building.

Recently, as the importance of railway transportation has become more important, various complaints have been increasing due to the increase of new and improved routes, gradual replacement to concrete tracks, increase in trains and increase in number of trains. The complaints about noise and vibration are a big obstacle to the revitalization of railway traffic and the creation of pleasant environment through reduction of noise and vibration of railway is becoming the biggest issue of railway. In particular, in the case of shipyard history, it is economical to minimize the area of the building and shorten the passenger line by constructing the history by utilizing the idle space below the railway in the section where the railway is constructed as a high-priced structure. However, It is difficult to create a pleasant indoor environment for employees and visitors in the region.

Referring to FIG. 1A, a railroad track 10 includes an upper structure 30 through which a train 40 is passed through a lower structure 30 where a person, such as a restaurant, 20, and in general, the upper structure 20 and the lower structure 30 are connected to each other by a fracture, so that the vibration is transmitted as it is. That is, vertical and horizontal vibrations are generated in the upper structure 20 when the train 40 enters and departs from the railroad track 10, and is directly transmitted to the lower structure 30, The structure 30 vibrates. Accordingly, the landing platform 50 also oscillates together with the lower structure 30 in a state of being simply supported by the lower structure 20.

On the other hand, unlike the above general structure type, as shown in Figs. 1B to 1D, some of the ship lading history systems introduce a system for blocking or reducing vibration in the vibration transmission path, or adopting a structure type for blocking or reducing vibration, There is also a format.

The system of Figures 1b and 1c is a floating track system that provides a vertical vibration damping bearing 26 at the bottom of the track 24 to block or reduce the vibration generated in the track 24 and transmitted to the historic structure.

The system of FIG. 1D supports the load of the upper structure between the upper structure 20 and the lower structure 30, and buffers the impact force transmitted between the upper structure and the lower structure due to a vertical earthquake or dynamic load during passage of the train , And a vertical vibration damping bearing (26) is installed to attenuate the vibration transmitted to each other.

1E, the bridges in which the tracks are installed are extended as they are in the historical section and the historic structures 12 are disposed on the left and right sides of the bridges 28 to prevent the vibrations generated in the tracks 24 from being transmitted to the historic structures 12 It is a TPS (Track on Pier System). This system is a method of blocking or reducing the vibration on the transmission path of the vibration, and the landing platform 50 is installed on the lower structure 30 in a simple supported state.
