The invention discloses a construction method for erecting a multi-layer viaduct. Used equipment comprises a beam lifter, a bridge erecting machine, an upper-layer beam transporting vehicle, a lower-layer beam transporting vehicle and a lower guide beam. The portal girder lifter lifts a bridge to the girder transporting vehicle, the girder transporting vehicle transports the bridge to the vicinity of the bridge girder erection machine, the girder transporting vehicle is matched with the guide girder to transport the bridge to a specified girder lifting position, and then the bridge girder erection machine lifts the bridge and places the bridge to a specified position. The bottom-layer bridges are firstly mounted, and then the upper-layer bridges are mounted one by one. The construction method comprises a bottom-layer bridge erecting procedure, an upper-layer bridge erecting procedure and a hole passing procedure of the bridge erecting machine, and the three procedures are circularly operated. The procurement cost of construction equipment can be greatly reduced, and the construction economic benefits are improved; the number of on-site constructors can be reduced, and the use efficiency of human resources is improved; cross construction of multiple devices is avoided, and the construction safety is greatly improved; all construction is carried out on bridges and piers, and ground traffic and environment are not affected.
本发明公开了一种多层高架桥架设施工方法,使用的设备包括提梁机、架桥机、上层运梁车、下层运梁车和下导梁;门式提梁机将桥梁提升至运梁车上,运梁车将桥梁运输至架桥机附近,运梁车配合导梁将桥梁运送至指定提梁位置,然后架桥机将桥梁提起,将桥梁落在指定位置。安装顺序按照先安装底层桥梁,然后逐一安装上层桥梁。施工方法包括底层桥梁架设工序、上层桥梁架设工序和架桥机过孔工序,上述三个工序循环操作。本发明可极大地降低施工设备的采购成本,提高施工经济效益;可减少现场施工人员数量,提高人力资源使用效率;避免了多设备交叉施工,极大提高了施工安全性;所有施工均载桥梁及桥墩上进行,不影地面交通及环境。
