铁道建筑

为统一GLC道岔结构标准，基于既有GLC道岔图纸及目前国内道岔制造单位的工艺，按照标准化、简统化的原则，对GLC道岔图纸进行结构统型和钢轨件部分优化修订。统型部分统一了封面，并增加了扣件安装及复合偏心套安装示意图，以便于生产和现场使用；总布置图中对岔枕长度和钢轨长度进行了统一，以满足特定的安装要求；转辙器尖轨高度统一修正为149.9 mm，以保证滑床台厚度的一致性；辙叉部分统一了防跳间隔铁、间隔铁、顶铁等的结构和尺寸，以提高互换性和维护效率。修改部分根据新发布的行业标准，对设计说明图中引用的标准名称及钢轨名称进行了修改；总布置图中修正了岔枕长度，调整了导曲线下股最后一根钢轨的长度，修改了明细表中的钢轨标准号；转辙器、辙叉及护轨部分钢轨件均进行了一定程度的修订。

In order to unify the structural standards of GLC turnouts, based on the existing GLC turnout drawings and the current processes of domestic turnout manufacturing units, the structural standardization and steel rail components of GLC turnout drawings were optimized and revised according to the principles of standardization and simplification. The standardization section has unified the cover and added schematic diagrams for fastener installation and composite eccentric sleeve installation for production and on-site use. The length of the turnout sleeper and the length of the steel rail have been standardized in the overall layout to meet specific installation requirements. The height of the switch point rail is uniformly corrected to 149.9 mm to ensure the consistency of the thickness of the sliding bed platform. The frog section has unified the structure and dimensions of anti-jumping spacing iron, spacing iron, top iron, etc. to improve interchangeability and maintenance efficiency. The modified section has made changes to the standard names and rail names referenced in the design explanatory drawing based on the newly released industry standards. The length of the switch sleeper has been corrected in the overall layout plan, the length of the last rail under the guide curve has been adjusted, and the rail standard number in the detailed table has been modified. The rail components of the switch, frog, and guard rail have been revised to a certain extent.
