Dragging and pushing construction method for large-span through steel truss bridge
The invention discloses a dragging and pushing construction method for a large-span through steel truss bridge, and relates to the technical field of bridge construction, and the dragging and pushing construction method comprises the following steps: erecting a steel truss girder support frame in a bridge construction area on one side of a river channel, and respectively erecting sliding brackets in bridge construction areas on two sides of the river channel; the steel truss girder component is assembled, and the steel truss girder component is assembled above the steel truss girder supporting frame; a steel cable guide device is arranged after the steel truss girder component is assembled in place, the steel cable guide device comprises a guide steel cable and a pulley, and the two ends of the guide steel cable are correspondingly connected with the two ends of the steel truss girder hook piece respectively; the pulleys comprise the first pulley and the second pulley, the first pulley is installed at the upper end of the steel truss girder supporting frame, the second pulley is installed at the upper end of the sliding support far away from the steel truss girder supporting frame, and the guide steel cable is connected with the first pulley and the second pulley in a winding mode. According to the application, the conditions of deflection and deviation in the slippage process of the steel truss girder component can be reduced.
本申请公开了一种大跨径下承式钢桁架桥拖拉顶推施工方法，涉及桥梁施工技术的领域，包括如下步骤：在河道其中一侧的桥梁建设区域搭设钢桁梁支撑架，在河道两侧的桥梁建设区域分别搭设滑移支架；拼装钢桁梁构件，将钢桁梁构件拼装于钢桁梁支撑架上方；钢桁梁构件拼装就位后设置钢索导向装置，钢索导向装置包括导向钢索和滑轮，导向钢索的两端分别与钢桁梁钩件的两端对应连接；滑轮包括第一滑轮和第二滑轮，第一滑轮安装在钢桁梁支撑架上端，第二滑轮安装于远离钢桁梁支撑架的滑移支架的上端，导向钢索分别与第一滑轮和第二滑轮绕设连接。本申请能够减少钢桁梁构件滑移过程中出现歪斜、偏移的情况。
