Construction method for erecting prefabricated box girder bridge girder erection machine in limited construction space
The invention discloses a construction method for erecting a prefabricated box girder bridge girder erection machine in a limited construction space. The construction method is characterized in that a main method for erecting the bridge girder bridge girder erection machine adopts high-low hoisting construction, so a girder lifting station is not arranged, a box girder is transported to an erection position through an offline transport vehicle, and is directly lifted and erected by the bridge girder erection machine, and the girder is lifted in the middle of an erection pier position; by adopting a mode that the front part is high and the rear part is low, box girders are in place through lifting and longitudinal moving of the crane carriage, 1-2 spans are installed through a crane before the bridge girder erection machine is installed so as to facilitate installation of the bridge girder erection machine, and compared with a traditional construction method, the cost of manpower, machinery and the like is saved, the construction speed is increased, and manufacturing cost is comprehensively saved by about 14%; and the crawler cranes and the truck cranes are arranged outside a double-machine span, inside and outside a single machine or inside the double-machine span through the crawler cranes and the truck cranes, and different hoisting modes can be selected according to different site conditions, so construction can be carried out in sites with limited construction spaces, and remarkable social benefits are achieved.
本发明公开了一种在施工空间受限预制箱梁架桥机架设施工方法，在架桥机架梁的主要方法是采用高低吊施工，因此不设置提梁站，通过线下运输车将箱梁运输到架设位置，由架桥机直接提梁、架梁，在架设墩位中间提梁，采用前高后低的方式，通过起重小车起升、纵移，实现箱梁就位，在安装架桥机之前先用吊车安装1～2跨，以方便架桥机的安装，与传统施工方法相比较，节约了人工、机械等费用，加快了施工速度，综合节约造价14％左右，并且通过履带吊和汽车吊按照双机跨外、单机内外跨或双机跨内布置履带吊和汽车吊，能够根据不同的场地情况选择不同的吊装方式，从而能够在施工空间受限制的场地进行施工，具有显著的社会效益。
