Large-span steel truss girder incremental launching construction device and method
The invention relates to a large-span steel truss girder incremental launching construction device and method, and belongs to the technical field of incremental launching construction. The device comprises a lifting cylinder, a lifting mechanism, a fixing mechanism, a guide frame and a positioning mechanism, the lifting cylinder is slidably arranged on a pier in a sleeving mode, the lifting cylinder is formed by oppositely hinging two arc-shaped plate bodies, and the lifting mechanism is arranged on the lifting cylinder and used for driving the lifting cylinder to move along the pier; the fixing mechanism is arranged on the lifting cylinder and connected with a bridge pier, the fixing mechanism is used for fixing the lifting cylinder and the bridge pier, the guide frames are arranged on the two sides of the lifting cylinder, and the positioning mechanism is arranged on the guide frames and used for positioning the steel truss girder moving to the guide frames. The method has the effect of improving the problem that the tail end of the steel truss can deviate in the incremental launching construction process.
本申请涉及一种大跨度钢桁梁顶推施工装置及方法，属于顶推施工技术的领域。其包括升降筒、升降机构、固定机构、导向架以及定位机构，所述升降筒滑动套设在桥墩上，且所述升降筒由两块弧形板体相对铰接而成，所述升降机构设置在升降筒上并用于驱动升降筒沿桥墩进行移动，所述固定机构设置升降筒上并与桥墩相接，所述固定机构用于将升降筒与桥墩固定，所述导向架设置在升降筒的两侧，所述定位机构设置在导向架上并用于对移动至导向架上的钢桁梁进行定位。本申请具有改善顶推施工过程中钢桁梁末端会发生偏移的问题的效果。
