Installation and construction method of large-span steel box girder bridge for spanning chemical pipe gallery
The invention discloses an installation and construction method of a large-span steel box girder bridge for crossing a chemical engineering pipe gallery, and relates to the technical field of chemical engineering. The method comprises the steps that movable supporting equipment supports a steel beam bridge, and through walking of the movable supporting equipment, a positioning mechanism moves to the extending end of the steel beam bridge along the steel beam bridge; a to-be-assembled steel frame is hoisted to the lifting mechanism, so that the top of the steel frame on the lifting mechanism is flush with the top of the existing steel beam bridge at the positioning mechanism, and the steel frame is driven by an electric telescopic rod to be attached to the existing steel beam bridge to be welded; according to the positions of different designed and arranged steel beam columns, constructors weld and fix the steel beam columns to the bottom of the steel beam bridge on the steel beam bridge. The movable supporting equipment is arranged at the extending end of the steel beam bridge, in the whole erecting process of the steel beam bridge, the operation position of constructors is supported by the movable supporting equipment all the time, shaking of the steel beam bridge during construction can be effectively avoided, and then the welding efficiency and the safety during construction are improved.
本发明公开了一种用于跨越化工管廊的大跨径钢箱梁桥安装施工方法，涉及化工技术领域。本发明包括移动支撑设备支撑钢梁桥，通过移动支撑设备行走，使得定位机构沿着钢梁桥移动至其延伸端；将待装配的钢架吊运到提升机构上，使得提升机构上的钢架顶部与定位机构处已有的钢梁桥顶部平齐，并通过电动伸缩杆带动钢架贴合已有钢梁桥焊接；根据设计布置的不同钢梁柱的位置，施工人员在钢梁桥上将该钢梁柱焊接固定在钢梁桥底部。本发明通过在钢梁桥延伸端设置移动支撑设备，在整个钢梁桥的搭设过程中，在施工人员作业位置处始终由移动支撑设备进行支撑，能够有效避免施工时钢梁桥的晃动，进而提高焊接的效率和施工时的安全性。
