                          枕木邊碎石的作用

                          2016-11-28 09:48:22 來源:人民鐵道網

                          鋼軌和枕木必須長期承受火車的重量,而碎石頭的一個任務是承擔防止鐵軌下陷的緩沖工作。另外,火車高速通過鋼軌,會產生噪音和高熱,而碎石頭的另外兩個重要工作就是吸收噪音和吸熱。

                            鋼軌和枕木必須長期承受火車的重量,而碎石頭的一個任務是承擔防止鐵軌下陷的緩沖工作。另外,火車高速通過鋼軌,會產生噪音和高熱,而碎石頭的另外兩個重要工作就是吸收噪音和吸熱。

                            大家如果注意,會發現鋼軌間鋪的石頭都是鑿碎的,形狀非常不規則,這樣的石頭容易碎裂,如此一來,就可以因為石頭的碎裂而吸收掉火車通過時所產生的高熱。如果鋪的是圓潤光滑的石頭,因為不容易碎裂,吸熱的效果就不好了。
