The invention provides a method for transporting a heavy prefabricated arch bridge assembled box girder in a remote area. The method comprises the following steps of a, providing two heavy low-gravity-center transport vehicles; b, building two steel rails extending from a starting place to a destination in parallel; c, synchronously installing two transport vehicles on the two steel rails; d, installing a winch on the fixed base at the destination, and connecting a steel wire rope to the two transport vehicles; e, placing the prefabricated arch bridge assembled box girder on the two transportvehicles through a jack; and f, starting the winch, using the steel wire rope to pull the two transport vehicles to synchronously move on the two steel rails, and transporting the prefabricated arch bridge assembled box girder to the destination. By using the method, manufacturing cost is low, installation is easy, and a transportation tonnage is large. The method is suitable for construction in remote areas, little in environmental damage, high in practicability, obvious in economic benefit and the like. Detaching is easy after a component is used.
本发明提供了一种在偏远地区运输重型预制拱桥拼装箱梁的方法。该方法包括如下步骤:a、提供两辆重型低重心运输车;b、修建两根由起始地平行延伸至目的地的钢轨;c、将两辆运输车同步安装在两根钢轨上;d、在目的地的固定基座上安装卷扬机,并将其钢丝绳连接至两辆运输车;e、用千斤顶将预制拱桥拼装箱梁搁置在两辆运输车上;f、启动卷扬机,钢丝绳牵引两辆运输车在两条钢轨上同步移动,将预制拱桥拼装箱梁运输至目的地。本发明具有造价低廉、安装简单、运输吨位大、适于偏远地区施工、用完后易于拆除、对环境破坏少、实用性强、经济效益明显等优点。
