Large-span multi-connection steel beam split-connection cutting control method
The invention belongs to the technical field of bridge construction, and particularly relates to a large-span multi-connection steel beam split-connection cutting control method which comprises the following steps: step 1, preparation work: after a steel box beam is pushed to a position above a pier column at a construction position through a pushing mechanism, the pushing mechanism is used for controlling the steel box beam to be lifted to a position above the pier column to form a cutting gap; according to the large-span multi-connection steel beam split-connection cutting control method, after incremental launching construction, an arranged cutting mechanism is used for automatically conducting automatic walking cutting operation on the temporarily-welded part of a steel box beam, a pressure sensor is used for monitoring the cutting extrusion pressure in real time in the cutting process, and the cutting position is automatically adjusted; by means of the cutting equipment, automatic surrounding walking cutting operation on the peripheral surface of the steel box girder is achieved, the cutting efficiency is improved, and the problems that in existing cutting, a cutting tool is manually held by hand for cutting operation, the cutting efficiency is low, and personnel injury is caused by spark splashing in the cutting process are avoided.
本发明属于桥梁施工技术领域，尤其是一种大跨多联钢梁分联切割控制方法，包括以下步骤：步骤一、准备工作：在钢箱梁通过顶推机构推行到施工位置的墩柱上方后，先利用顶推机构控制钢箱梁提升位于墩柱的上方形成切割间隙。该大跨多联钢梁分联切割控制方法，本发明通过在顶推施工后利用设置的切割机构自动对钢箱梁临时焊接的部位进行自动行走切割操作，切割中还利用压力传感器实时监测切割的挤压压力，自动调整切割位置，利用切割设备实现在钢箱梁的四周表面自动围绕行走切割操作，增强切割的效率，避免了现有的切割中都是人工手持切割工具进行切割操作，切割效率慢以及切割中的火花飞溅造成人员伤害。
