Auxiliary device and method for pushing construction of through steel truss arch bridge
The invention discloses an auxiliary device and method for pushing construction of a through steel truss arch bridge, and the auxiliary device comprises walking jacks located at the tops of two rows of multiple temporary piers, and two steel bearing beams between two steel longitudinal beams of which the bottom surfaces are inverted V-shaped longitudinal slopes with high middle parts and low two ends along the length direction, the top plane and the bottom plane of each steel bearing beam are parallel, a plurality of sets of steel cushion block assemblies are fixed to the top plane of each steel bearing beam, and the top face of each steel cushion block and the bottom inclined face of the length position of each steel longitudinal beam are consistent in gradient and attached to each other. The length of each steel bearing beam is smaller than that of each steel longitudinal beam, each steel bearing beam and the steel guide beams at the two ends of each steel bearing beam are integrated, and the steel guide beams at the two ends of each steel bearing beam are cut off after the through steel truss arch bridge is pushed in place. When the auxiliary device is adopted for incremental launching construction, the main steel beam of the bridge cannot be damaged, only a normal reinforcing structure and a supporting structure are needed for the joint of the steel guide beam, and steel is relatively saved.
本发明公开了一种下承式钢桁架拱桥顶推施工用辅助装置和方法，辅助装置包括位于两排多个临时桥墩顶部的步履式千斤顶与底面为沿长度方向中间高两端低的倒V字形状纵坡的两根钢纵梁之间的两根钢垫梁，每根钢垫梁的顶平面与底平面平行，每根钢垫梁的顶平面上固定有多组钢垫块组件，每块钢垫块的顶面与所处的每根钢纵梁的长度位置的底斜面坡度一致并相互贴合；每根钢垫梁的长度均短于每根钢纵梁的长度，每根钢垫梁与两端的钢导梁均为一个整体，每根钢垫梁两端的钢导梁均为下承式钢桁架拱桥顶推到位后被切割掉的钢导梁。采用本辅助装置顶推施工过程不会伤害桥梁的主钢梁，对于钢导梁连接处只需正常加固结构和支撑结构即可，且相对节省钢材。
