The invention discloses a bailey beam dismantling construction method in bridge engineering. The method is characterized by comprising the following steps: a, after completion of pouring of a bridge plate concrete structure in bridge engineering, starting to dismount bailey beams under the condition of conforming to support scaffold dismounting permission; b, starting supporting descending devicesat the two ends of the bailey beam; c, dividing a plurality of bailey beams into groups, each of which includes two bailey beams, enabling a channel beam to pass through the two bailey beams in one group for series connection; d, after jacking up of the bailey beams, providing a plurality of pieces of round steel and laying the round steel on I-shaped steel in parallel; e, installing a winching machine at the end of each I-shaped steel row at the two ends of the bailey beams respectively to hoist a crane above a bridge plate conveniently so as to transport the bailey beams, thereby completingbailey beam dismounting rapidly. According to the invention, the bailey beam dismantling construction method in the bridge engineering has the advantages that bailey beam single beams can integrallymove, hoisting dismantling is achieved, quick dismantling is achieved, the engineering quality is safe and reliable, the high-altitude operation personnel are reduced, potential safety hazards are reduced, the construction period is shortened, and the construction cost is indirectly saved.
一种桥梁工程中贝雷梁拆除施工方法，其特征在于包括以下步骤：a、当桥梁工程中桥板混凝土结构浇筑完成，并符合支撑脚手架拆除许可后开始贝雷梁拆除，b、启动贝雷梁两端支撑下降装置，c、将若干个贝雷梁分成每两个贝雷梁为一组，使一组中的两个贝雷梁端头之间穿入槽钢进行串联，d、顶起贝雷梁后，提供若干圆钢平行铺设在所述工字钢上，e、分别在贝雷梁两端每排工字钢端头安装一台卷扬机，以便设置于桥板上方的吊车吊装、运走贝雷梁，快速完成拆除贝雷梁。本发明的桥梁工程中贝雷梁拆除施工方法具有贝雷梁单体梁可整体移位、吊装拆卸实现快速拆除，工程质量安全可靠，减少高空作业人员，降低安全隐患，压缩工期和间接节省施工成本的优点。
