鸿宝聚乙烯枕木
枕木又称轨枕，只不过现在所用材料不仅仅是木材，因此叫轨枕更加科学。别看轨枕的模样单调划一，貌不惊人，它的作用可不小。轨枕既要支承钢轨，又要保持钢轨的位置，还要把钢轨传递来的巨大压力再传递给道床。它必须具备一定的柔韧性和弹性，硬了不行，软了也不行。
Sleepers, also known as sleepers, are now more than just wood, so they are more scientific. Do not look at the monotonous appearance of the sleeper, the appearance is not surprising, its role is not small. The sleeper must support both the rails and the position of the rails, and transfer the great pressure from the rails to the track bed. It must have a certain degree of flexibility and flexibility. If it is hard, it will not work.
