随着我国铁路建设事业的飞跃发展,为了节約木材和改进线路质量,钢筋混凝土轨枕在我国铁路上大量推广使用,配合混凝土轨枕的使用专业院會編制了一些钢筋混凝土轨枕用扣件图紙(大部分图紙是与铁道科学研究院共同編制的)。十年来,在实践中现场对探用材质,结构型式尺寸等提出了不少改进意見,有些图紙先后作了一些改进。另外,为了配合其他新型轨下基础的铺设,如整体道床,无碴无枕砼梁等,只設計了一些扣件试铺或推广使用。现将常用的图紙及尚有参考价值的图紙的設計内容概况及修改情况,列述如下,供参考。
With the rapid development of China’s railway construction, in order to save wood and improve the quality of the line, a large number of reinforced concrete sleepers are widely used in our country’s railways. With the use of concrete sleepers, the professional institutes have compiled some drawings of fasteners for reinforced concrete sleepers Most drawings are co-developed with the Academy of Railway Science). In the past ten years, many opinions on improvement have been put forward in the field on materials used for exploration, structural type and size, and some drawings have made some improvements in succession. In addition, in order to tie in with the laying of other new rail-based foundation, such as the overall ballast, ballastless pillow concrete beam, etc., only designed some fasteners shop or promote the use of. Now commonly used drawings and drawings of reference value of the design content and changes are listed below for reference.
