Tower area steel box girder construction method
The invention relates to the field of steel box girder installation, in particular to a tower area steel box girder construction method which comprises the following steps that steel box girders are manufactured in a factory in a segmented mode and transported to the position close to a bridge site on one side of a river channel, a pushing platform is erected at the position of a bridge abutment, and a sliding way and a pushing device are arranged; a first steel box beam is hoisted on a pushing platform, all the stages are welded into a whole, a guide beam is installed on the front section of the first steel box beam, a motor traction device is arranged on the opposite shore, and in order to prevent the steel beam from being twisted and deformed, a shear block is additionally arranged in the steel beam. The steel box girders are manufactured in a segmented mode in a factory, the manufacturing quality can be guaranteed under the control environment, meanwhile, the manufacturing speed is increased, a pushing platform is erected at the bridge abutment position, a sliding way and a pushing device are arranged, continuous pushing and traction of the steel box girders are achieved, on-site welding and reinforcing work is reduced, the construction efficiency is improved, and by means of the pushing and traction technology, the construction cost is reduced. The position and the line type of the steel box girder can be accurately controlled, and the construction quality is guaranteed.
本发明涉及钢箱梁安装领域，具体涉及一种塔区钢箱梁施工方法，包括以下步骤：工厂分段制造钢箱梁，运至河道一侧桥位附近，在桥台位置搭设顶推平台、布设滑道、顶推装置；在顶推平台上吊装第一条钢箱梁，将各阶段焊成一整体，第一条段前段安装导梁，并在对岸设置电机牵引装置，为防止钢梁扭曲变形，在钢梁内加剪力块。本发明中通过工厂分段制造钢箱梁，可以在控制环境下保证制造质量，同时加快制造速度，在桥台位置搭设顶推平台、布设滑道、顶推装置，实现了钢箱梁的连续顶推和牵引，减少了现场焊接和加固工作，提高了施工效率，通过顶推和牵引技术，可以精确控制钢箱梁的位置和线型，保证了施工质量。
