Overall incremental launching construction method for large-span steel truss bridge
The invention relates to a large-span steel truss bridge integral incremental launching construction method which comprises the steps that S1, a temporary support is built, an incremental launching platform and a sliding way are included, and the sliding way is fixed to the top of the incremental launching platform; s2, a temporary splicing platform is built; s3, a pushing device is installed, the pushing device is installed at the top of the pushing platform, and the pushing device is used for pushing the beam body in the vertical direction and pushing the beam body forwards at the same time; the pushing device comprises a first hydraulic cylinder, and the first hydraulic cylinder is erected on the slide way; the slide way comprises a plurality of pin rollers which are horizontally arranged, and the pin rollers are rotationally connected with the pushing platform; s4, a guide beam is arranged firstly, then steel truss unit sections are built behind the guide beam, pushing is conducted once after one unit section is assembled, and the steps are repeated; and S5, after complete pushing of the steel truss bridge is completed, beam falling is conducted, the whole steel truss bridge is completely and accurately located on the bridge piers, and the effects that the friction force between the beam body and the pushing platform during pushing of the beam body is reduced, and the smoothness during pushing of the beam body is improved are achieved.
本申请涉及一种大跨度钢桁架桥梁整体顶推施工方法，其包括S1、临时支撑的搭建，包括顶推平台和滑道，滑道固定在顶推平台顶部；S2、搭建临时拼装平台；S3、顶推装置的安装，顶推装置安装在顶推平台顶部，顶推装置用于将梁体向竖直方向顶起，同时将梁体向前方推动；顶推装置包括第一液压缸，第一液压缸架设在滑道上；滑道包括滚柱，滚柱水平设置有多根，滚柱与顶推平台转动连接；S4、先设置导梁，而后在导梁后搭建钢桁架单元节，拼装完一节单元节即顶推一次，如此往复；S5、钢桁架桥梁完全顶推完毕后，进行落梁，整个钢桁架桥梁完全精准的坐落在桥墩上，本申请具有减少梁体推动时与顶推平台之间的摩擦力，提升对梁体推动时顺畅度的效果。
