Construction method of walking type sliding pushing for bridge construction
The invention discloses a construction method of walking type sliding pushing for bridge construction. The construction method comprises the following steps: steel trussed beams are assembled on site,pushing power is distributed, the steel trussed beams are jacked, steel trussed beam sliding blocks are replaced, the steel trussed beams are pushed to transversely move on a sliding way beam, trussbeam joints slide out of a sliding rail, the steel trussed beams are jacked again, and cyclic pushing is conducted till the steel trussed beams reach the designed position. Compared with a traditionalpushing mode, the walking type sliding pushing construction method for bridge construction has the advantages that the horizontal pushing force borne by buttresses can be effectively reduced, the stress of a bridge structure is improved, the requirements for overall stability and local stability during bridge pushing construction are greatly met, and innovation and development in the bridge pushing field are seen from the outside.
本发明公开了一种桥梁施工用步履式滑移顶推的施工方法，所述施工方法由以下步骤组成：钢桁梁现场拼装，顶推动力的布设，顶升钢桁梁，置换钢桁梁滑块，在滑道梁上顶推横移，桁架梁节点即滑出滑轨，再次顶升钢桁梁，循环顶推直至到达设计位置；本发明作为一种桥梁施工用步履式滑移顶推的施工方法，较传统顶推方式而言，能有效减小支墩所受的水平推力，改善桥梁结构受力，大大保证了桥梁顶推施工时的整体稳定性和局部稳定性要求，让外界看到了桥梁顶推领域的创新与发展。
