轨枕是钢轨的基础,是铁路线路上部建筑的重要组成部分。自铁路诞生的一百五十多年中,木枕一直是传统的轨枕,早已被人们所熟习,并且一直延用到现在。随着水泥工业的发展,而后又出现了混凝土枕。至于钢枕,人们对它还了解甚少,比较陌生。 Sleepers are the foundation of the rails and are an important part of the construction of the upper part of the railway line. For more than 150 years since the birth of the railway, wooden pillows have traditionally been sleepers that have long been familiar to people and have been used until now. With the development of the cement industry, concrete pillows then appeared. As for the steel pillows, people still know little about it, are unfamiliar.
