摘要
结合山区高速公路梁板预制与架设施工难点,详细介绍了利用高低腿龙门吊将预制梁提升到桥面,然后用运梁小车将箱梁运到架桥机下面进行预制梁架设的方法,进而为山区高速公路施工提供了丰富的经验。
Combining with construction difficulties beam and slab pre-casting and construction difficulties on mountainous highway,this thesis introduces pre-cast beam construction method,which is to use high-low gantry crane for hoisting pre-caste beam to the bridge,then transports box girder under the bridge erection machine with beam-transported car.Thus,it has provided rich experience for mountainous highway construction.
