桥梁是铁路的重要组成部份,桥枕是桥面重要设备之一。桥枕的作用是直接承受由钢轨传来的外力,均衡的分布到钢梁上,同时固定钢轨位置,防止钢轨倾覆和位移。因此,桥枕状态是否良好,直接影响铁路运输的安全与畅通。为了保证桥枕状态良好,除了加强日常养护维修工作外,在桥枕铺设前,提高加工制做质量,是重要的一个环节。我国铁路桥梁数量多,每年大修维修需 Bridge is an important part of the railway, bridge deck is one of the important equipment. The role of the bridge pillow is directly subjected to external forces from the rail, a balanced distribution to the steel beam, while fixing the rail position to prevent rail overturning and displacement. Therefore, the status of the bridge is good, a direct impact on the safety of railway transport and smooth. In order to ensure that the bridge is in good condition, in addition to strengthening the daily maintenance and repair work, it is an important step to improve the quality of processing before the bridge is laid. The number of railway bridges in our country is overhaul each year
