Steel box girder traction rapid construction method
The invention provides a rapid construction method for steel box girder traction. The rapid construction method comprises the following steps that a plurality of temporary supports, traction supports and girder falling supports are sequentially erected at intervals in the traction direction; a plurality of first guide parts are arranged on the supporting part, and a plurality of second guide parts are correspondingly arranged on the bottom surface of the steel box girder; during traction, the first guide component and the second guide component are in sliding guide fit to guide traction movement of the steel box girder, mid-span deflection deformation of the steel box girder is monitored in real time through the first inclinometer in the traction process, and deflection deformation of the free end of a guide girder at the front end of the steel box girder is monitored in real time through the second inclinometer. The traction movement of the steel box girder is guided through the sliding guide fit of the first guide part and the second guide part, the deviation of the traction movement of the steel box girder can be reduced as much as possible or even avoided, and the mid-span deflection deformation of the steel box girder is monitored in real time through the first inclinometer in the traction process; the second inclinometer monitors the deflection deformation of the free end of the guide beam at the front end of the steel box beam in real time, and safe construction is guaranteed.
本发明提出一种钢箱梁牵拉快速施工方法，包括如下步骤：沿牵拉方向依次间隔架设多个临时支架、牵拉支架和落梁支架；支撑部件上布设多个第一导向部件，钢箱梁底面上对应布设多个第二导向部件；牵拉时，第一导向部件与第二导向部件滑动导向配合对钢箱梁的牵拉移动进行导向，且牵拉过程中通过第一倾角仪实时监测钢箱梁的跨中挠度变形，第二倾角仪实时监测钢箱梁前端导梁自由端的挠度变形。本发明通过第一导向部件与第二导向部件滑动导向配合对钢箱梁的牵拉移动进行导向，可尽可能地降低甚至避免钢箱梁牵拉移动发生偏移，牵拉过程中通过第一倾角仪实时监测钢箱梁的跨中挠度变形，第二倾角仪实时监测钢箱梁前端导梁自由端的挠度变形，保证安全施工。
