Construction method for dismantling overpass bridge of overpass railway
The invention discloses a demolition construction method for an overpass bridge of an over-crossing railway. The demolition construction method for the overpass bridge of the over-crossing railway comprises the following steps that fences on the two sides of an existing railway are moved and changed, temporary fences are arranged, and permanent fences are demolished; before construction, a return line between supporting columns is temporarily changed into a cable line; after the first half range of the expressway is closed, a first half range pier beam dismounting platform is arranged, and a first half range old bridge is dismounted through a bridge erecting machine; newly building a lower structure of a first half bridge, erecting prefabricated box girders, constructing bridge deck accessories, and completing a new building procedure of a west half bridge; after the first half range is newly built and the second half range of the expressway is closed, a second half range pier beam dismounting platform is arranged, and a second half range old bridge is dismounted through the bridge erecting machine; the second half bridge lower structure is newly built, the prefabricated box girders are erected, bridge deck accessories are constructed, the second half bridge is newly built, the overpass railway overpass bridge can be rapidly supported, and the construction period is shortened.
本发明公开了一种上跨铁路立交桥梁拆除施工方法，上跨铁路立交桥梁拆除施工方法包括如下步骤：对既有铁路两侧栅栏迁改，设置临时栅栏，拆除永久栅栏；施工前将支柱间回流线临时改为电缆线路；高速公路第一半幅封闭后，设置第一半幅墩拆梁平台，采用架桥机拆除第一半幅老桥；新建第一半幅桥梁下部结构，架设预制箱梁，施工桥面附属，完成西半幅桥梁新建工序；第一半幅新建完成后，封闭高速公路第二半幅后，设置第二半幅墩拆梁平台，采用架桥机拆除第二半幅老桥；新建第二半幅桥梁下部结构，架设预制箱梁，施工桥面附属，完成第二半幅桥梁新建，该上跨铁路立交桥梁拆除施工方法，能够快速实施对上跨铁路桥梁进行支撑，缩短施工周期。
