CONCRETE LONG-SLEEPER BLOCK FOR FAST-HARDENING TRACK TO IMPROVE RAILWAY TRACK WITH CONSIDERATION FOR TRAIN SERVICE AND CONSTRUCTION METHOD THEREOF

摘要

Provided are a concrete long-sleeper block for a fast-hardening track to improve a railway track with consideration for a train service, and a construction method thereof. To improve the railway track on a gravel roadbed within a train suspension time in consideration of the train service, the constructing method is capable of forming a concrete panel by injecting fast-hardening non-shrinkage mortar after installing the concrete long-sleeper block; thereby forming the concrete long-sleeper block for a fast-hardening track. Accordingly, the suspension of the train service is able to be minimized by promoting a reduction for a roadbed construction time and the rapidity of the maintenance of the roadbed. In addition, the construction method is capable of reducing the amount of the fast-hardening non-shrinkage mortar by densely arranging the concrete long-sleepers, improving a resistance to a vertical load of a railway vehicle, preventing deformation and distortion of the concrete long-sleeper, securing operational safety even though a plurality of concrete long-sleepers are densely arranged, and saving and reducing construction costs and construction time of the fast-hardening track.;COPYRIGHT KIPO 2017
