고속선 도상자갈 재활용을 위한 건식자갈세척장비 개발에 관한 연구

초록

Roadbed of a railway has to been impacted by a train or the roadbed itself. Generally roadbed of a railway consists of gravel and high-speed train needs a lot of ballast gravel because it absorbs the impact from a train. High-speed railway ballast gravels are required periodic replacement. However, used ballast gravels are divided to the environmental waste. Therefore, the changing progress of ballast gravels generates a lot of environmental waste and needs high cost. For this reason, we develop the waterless gravel cleaning equipment which can reduce the amount of environmental waste and cost. This paper describe the step of waterless gravel cleaning and development of waterless cleaning equipment for gravel.
