摘要
为了改善水泥混凝土路面切缝质量、提高切缝效率,目前筑路工程界已广泛采用锯切技术,即使用带有高速旋转锯刀盘的锯缝机直接在水泥路面上锯切出等宽缝隙。无疑,控制水泥路面缝隙宽度的重要因素之一,还在于锯缝机锯刀盘上切削刃的厚度。本文以“既要确保环境温度改变时水泥路面不出现裂缝又要保证水泥路面实际使用时具有一定的舒适性及足够的安全性”为原则,经过系统的分析及研究提出一项锯缝机锯刀盘切削刃合理厚度的理论设计公式。按照本文推荐的公式及有关已知参数,筑路机械设计制造者及筑路施工技术人员很易确定适用于当地筑路区域的锯刀盘切削刃合理厚度。
The saw cutting technolgy has been widely used in present road engineering in order to improve the cutting quality of cement concrete pavement and cutting efficiency. The article adheres to the principle of preventing the cement concrete pavement from cracking when enviormental temperature changes and ensuring a considerable comfort and safety when driving on it. It suggests theoretically a design formula of reasonable thickness of the cutting blade of cement concrete saw plate on the basis of the systematic analyses and studies.
