为了进一步了解隧道內整体道床的技术狀况,第一設計院今年曾派人至丰沙线,隴海线,銅王线,乔新线四个隧道工点进行了重点調查,並已提出了初步的文字报告,其中涉及整体道床結构类型、扣件形式、施工方法及设计特点等方面。簡要結論有如下几点: 1.現有木枕(短枕、长枕、长短枕間隔)整体道床均存在缺陷。这种結构木材消耗仍很多,如短枕,每公里需55M~3,长枕每公里需160M~2,日軌线支承形式设有改善。木枕的
In order to further understand the technical condition of the entire track bed in the tunnel, the First Institute of Design dispatched four tunneling stations to the Fengsha Line, Longhai Line, Tongwang Line and Qiao Line this year to conduct a survey and put forward Initial text report, which relates to the overall type of ballast structure, fastener forms, construction methods and design features and other aspects. A brief conclusion has the following points: 1. The existing wooden pillow (short pillow, long pillow, long pillow interval) the overall track bed defects. This structure is still a lot of timber consumption, such as short sleepers, 55M ~ 3 per km, long pillow 160M ~ 2 per km, with the form of rail support has been improved. Wood pillow
