跨高铁咽喉区连续梁挂篮防护施工技术研究

Study on the construction technology of continuous beam protection in high-speed tailway throat area

跨越高铁咽喉区连续梁施工,铁路线路密集、设备多、防护面积大、净空受限,采用常规防护棚架投资大、安装拆除周期长、对既有线运营影响大,通过在挂篮上采用封闭、绝缘、接地等保护措施,既保证了高速铁路运营安全,也保证了连续梁本身施工工期,节约了成本,为连续梁跨越既有高速铁路咽喉区施工提供了新的思路,具有较高的参考价值。

Continuous beam construction in high-speed railway throat area,railway lines,equipment,protective area is large,more dense clearance limited,the conventional protective sheds investment big,installation and dismantle cycle is long,for existing lines in operation effect,by using closed on the hanging basket,insulation,grounding protection measures,to ensure the safety of the high-speed railway,both also ensures continuous beam itself construction period,save the cost,for the continuous beam span both the throat area of high speed railway construction provides a new train of thought,has the high reference value.
