It is about.

일반적으로 침목은 레일도상(道床)에 일정 간격으로 배열되어 그 위에 레일을 깔고 정착시킴으로써 궤간(레일과 레일 사이의 간격)을 정확히 유지시키고, 또 레일에 가해지는 열차하중을 도상을 통해 노반(路盤)에 전달하는 것이다.In general, the sleepers are arranged at regular intervals on the rail, and the rails are laid on and fixed on the rails so that the tracks (gaps between the rails and the rails) are maintained accurately and the train loads applied to the rails are laid on the roadbed. ) To pass.

이와 같은 기능을 갖는 침목의 소재로는 일반적으로 목재가 주로 이용되어 왔으나, 목재는 중량이 가볍고 취급이 용이한 반면 부패하는 결점이 있고 산림의 훼손으로 자원을 고갈시키는 등의 문제점이 있다.As a material for sleepers having such a function, wood has generally been mainly used, but wood has a problem such as being light in weight and easy to handle while depleting defects and depleting resources due to forest damage.

따라서, 근래에는 콘크리트 침목이 주로 사용되고 있으며, 상기 콘크리트 침목은 침목 형상을 갖는 거푸집내에 콘크리트를 타설하고 공기중에서 양생시킨 후 거푸집으로부터 양생된 침목을 취출하는 방식으로 제조가 이루어진다.Therefore, in recent years, a concrete sleeper is mainly used, and the concrete sleeper is manufactured by pouring concrete into a form having a sleeper shape and curing in air, and then taking out the cured sleeper from the formwork.
