Rail track design & construction

Rail track design & construction

1. Rail Track Design and development

Unlike general railway tracks, tram tracks have relatively small working loads, operate at low speeds, and have a small track curve radius, so track design considering rail-wheel interaction is an important factor for track maintenance and safety.
Due to the characteristics of tram track constructed on the road, various types of track structure and surface finish form are applied in consideration of drainage measures, so appropriate technology application is required at the design stage.


2. Rail Track construction

ERS Trough Construction Method(Patent No 10-2078321)

  • In ERS Trough construction of the rail reclamation track system, the groove installation is closely related to the cost of the rail fixing resin and the rail alignment, so the precision of the rail linear construction error level is required.
  • Therefore, for the precise construction of rail grooves, it is important to have construction experience by special construction methods, and our patented construction method enables such precise construction and is applied to many sites.

ERS Slab Construction Method(Patent No10-1669461)

  • Tram track construction is usually constructed in a narrow road space, so the installation of cranes may be restricted.
  • In a construction situation, it is necessary to mount the precast slab at the bottom to be able to move the narrow space and stably connect the slab.
  • Our company has a patented method using such a special bogie and has proven its practicality by applying it in the construction of the Osong Tram Test Line.

Concrete Slab Settlement Restoration Method (ERSRR)

  • ERSRR is a slab track system that requires a technique for restoring the ground under the ground and restoring the position of the slab settled to its original position.
  • We have the technology of restoring the track slab using polyurethane expansion resin, so it is possible to respond quickly to the sinking of the track slab that may occur during tram line operation.

Tram Rail Inspection & Refurbishing

  • For the stable operation of the tram line, it is important to secure economical track maintenance technology.
  • We have rail maintenance technology for turnouts and general parts buried in the road and enable quick and economical maintenance.
  • In addition to the repair of worn rails, tram tracks must be carried out in accordance with regular maintenance plans, such as snow removal and track cleaning.

Engineering

  • We are the first Korean tramway developer to develop tram track technology unique to track design, analysis, construction and maintenance.
