Double-slope one-way variable-posture incremental launching construction device and method for steel truss girder
The invention provides a double-slope one-way variable-posture pushing construction device and method for a steel truss girder, the device comprises temporary piers, a pier-side bracket, a steel truss girder pushing assembly platform, a steel truss girder in-situ assembly platform and a walking pushing system, and the large mileage side and the small mileage side of the vertex of a double-slope vertical curve of the steel truss girder are each provided with one temporary pier; a pier-side bracket is arranged on each of the two sides of the permanent pier in the pushing direction of the steel truss girder; the steel truss girder pushing and assembling platform is arranged on one side of a steel truss girder pushing starting point; a steel truss girder in-situ splicing platform is arranged in the downstream direction of the steel truss girder pushing and splicing platform; walking pushing systems are arranged at the tops of the temporary piers, the pier-side brackets and the permanent piers where the steel truss girders are located; a movable lifting cushion block is arranged on each walking pushing system; double-slope incremental launching construction of the steel truss girder is achieved, rigid rotation of the main girder is avoided, the construction efficiency can be improved, and construction safety is guaranteed.
本发明提供的一种用于钢桁梁的双坡单向变姿态顶推施工装置及方法，包括临时墩、墩旁托架和钢桁梁顶推拼装平台、钢桁梁原位拼装平台和步履顶推系统，其中，所述钢桁梁的双坡竖曲线顶点的大小里程侧分别设置有一个临时墩；位于钢桁梁顶推方向的永久墩两侧均设置有一个墩旁托架；所述钢桁梁顶推拼装平台置于钢桁梁顶推起点一侧；所述钢桁梁顶推拼装平台的下游方向设置有钢桁梁原位拼装平台；所述临时墩、墩旁托架及钢桁梁所处永久墩的顶部均设置有步履顶推系统；所述每个步履顶推系统上均设置有活动抄垫块；本发明实现钢桁梁双坡顶推施工，避免了主梁的刚性转动，有利于提高施工效率，保证施工安全。
