Steel box girder pushing traction system and construction method thereof
The invention discloses a steel box girder pushing traction system and a construction method thereof. The steel box girder pushing traction system comprises a first suspension anchor pulling device; second suspension anchor pulling devices; a slideway assembly which comprises a chassis, balls and a buffer plate; and a bottom plate which is connected with a temporary support used for moving the steel box girder. The chassis bears the balls and the buffer plate. The first suspension anchor pulling device is arranged at the tail of the steel box girder, and the second suspension anchor pulling devices are arranged under a middle web plate of the steel box girder. The first suspension anchor pulling device and the multiple second suspension anchor pulling devices work together to be matched with the steel box girder for pushing and hoisting, and the slideway assembly bears the steel box girder and conducts auxiliary adjustment on the pushing operation direction of the steel box girder. Thetechnical problems that in conventional steel box girder pushing construction, a steel box girder is large in dead weight, and resistance friction between a bottom plate of the steel box girder and asliding way is large, so that the steel box girder is not prone to direction adjustment in the pushing process, and the method cannot be suitable for pushing and direction changing of the steel box girder with a complex curve are solved.
本发明申请公开了一种钢箱梁顶推牵引系统及其施工方法。该钢箱梁顶推牵引系统包括第一拉悬挂锚器和第二悬挂拉锚器；滑道组件，包括底盘、滚珠和缓冲板；底板与用于移动钢箱梁的临时支架连接，底盘承载滚珠和缓冲板；第一悬挂拉锚器设置在钢箱梁的尾部，多个第二悬挂拉锚器设置在钢箱梁的中腹板下方；第一悬挂拉锚器和多个第二悬挂拉锚器共同作业配合钢箱梁进行顶推起吊，滑道组件承接钢箱梁，对钢箱梁的顶推作业方向进行辅助调整。本发明申请解决了由于常规的钢箱梁顶推施工中，钢箱梁自重大，钢箱梁底板与滑道阻力摩擦大，造成的钢箱梁在顶推过程中不容易进行方向的调整，无法适用于复杂曲线钢箱梁顶推变向的技术问题。
