架桥机在营业线更换T梁中的应用

Application of Bridge Erecting Machine in the Replacement of T Beam in Business Line

由于既有铁路设计标准低,施工工艺落后及运营年度久远,部分桥梁出现不同程度的病害。为满足铁路提速、重载和人民多种出行方式的需求,铁路设备急需提级改造。但由于地理环境、施工工艺、运输条件限制,个别桥梁更换施工难以实施,影响整条铁路运输能力的改善和提升。介绍使用架桥机在营业线上更换T梁技术,解决了传统吊装更换及预铺横移更换等方式难以实现的施工。

Because of the low railway design standards,backward construction technology and long-term operation,some bridges have different degrees of disease.In order to meet the needs of railway speed-increasing,heavy-duty and people’s multiple modes of travel,railway equipment is in urgent need of upgrading.However,due to geographical environment,construction technology and transportation conditions,it is difficult to implement individual bridge replacement construction,which will affect the improvement and improvement of the entire railway transportation capacity.Introduce the use of bridge erecting machine to replace T beam technology on the business line,and solve the construction that is difficult to achieve in the traditional hoisting replacement and pre-laying traverse replacement.
