Variable cross-section steel bridge incremental launching construction auxiliary device and construction method
A variable cross-section steel bridge incremental launching construction auxiliary device comprises a plurality of auxiliary units (1) arranged in sequence, the upper ends of the auxiliary units (1) are fixed to the bottom of a variable cross-section steel bridge (7), and the lower ends of the auxiliary units (1) are located on the same horizontal plane. The auxiliary unit (1) comprises a supporting structure and a bottom plate (4); a plurality of sliding grooves are formed in the lower portion of the bottom plate (4), and the arrangement direction of the sliding grooves is in the longitudinaldirection of the variable cross-section steel bridge (7). According to the variable cross-section steel bridge incremental launching construction auxiliary device, the auxiliary units with the variable heights are welded below the variable cross-section steel bridge in advance, so that the bottom of the steel bridge above the sliding rail is in the horizontal plane, and the incremental launchingconstruction difficulty is reduced. The variable cross-section steel bridge incremental launching construction auxiliary device is simple in structure and easy and convenient to construct, the construction cost is saved, and the construction period is shortened.
变截面钢桥顶推施工辅助装置，包括依次排列的若干辅助单元(1)，辅助单元(1)上端固定在变截面钢桥(7)底部，辅助单元(1)的下端处于同一水平面上。辅助单元(1)包括支撑结构和底板(4)，底板(4)下部排列有具有若干滑槽，滑槽的排列方向沿变截面钢桥(7)纵向。本发明的变截面钢桥顶推施工辅助装置，通过在变截面钢桥下预先焊接若干高度变化的辅助单元，使得在滑移轨道上方的钢桥底部呈水平面，降低了顶推施工的难度。本发明的变截面钢桥顶推施工辅助装置构造简单、施工简便，节省了施工成本，缩短了施工周期。
