Narrow steel box girder erection method
The invention relates to the field of rail transit equipment, and discloses a narrow steel box girder erection method which comprises the following steps: step 1, mounting pushing equipment on each temporary buttress; an auxiliary support is installed on the side face of a pier, a connecting part is arranged between the auxiliary support and the pier, a sliding rail is arranged on the connecting part, and a sliding block is slidably connected to the sliding rail; secondly, a rotating support is installed on the side, away from the pushing starting point, of the pier; mounting a rotating part on the lower surface of the rear end of the box girder; thirdly, the front end of the box girder is moved to the position of an auxiliary support of the second pier and connected with a sliding block, the rear end of the box girder is moved to the position of the first pier, and a rotating part is placed in a rotating groove; fourthly, the front end of the box girder and the sliding block slide to the second pier on the sliding rail together, and the box girder rotates with the rotating part as the circle center; the method is low in construction difficulty, wide in application range and suitable for small-radius and large-span rail transit construction.
本发明涉及轨道交通设备领域，公开了一种窄幅钢箱梁架设方法，包括以下步骤：步骤一、在每个临时支墩上安装顶推设备；在桥墩侧面安装辅助支架,辅助支架和桥墩之间设有连接部，连接部上设有滑轨，滑轨上滑动连接有滑块；步骤二、在桥墩上远离顶推起点一边安装转动支座；在箱梁后端下表面安装转动部；步骤三、将箱梁前端移动到第二个桥墩的辅助支架位置并和滑块连接，将箱梁的后端移动到第一个桥墩位置并将转动部放在转动槽内；步骤四、将箱梁前端和滑块一起在滑轨上滑动至第二个桥墩上，箱梁以转动部为圆心进行转动；本方法施工难度低、适用范围广、适用于小半径、大跨径的轨道交通建设。
