The invention discloses an offshore bridge section sliding installation method based on an SPMT and a jack, the SPMT and a bridge section are carried by a barge to reach the position between slide way beams extending out of bridge piers, the SPMT is used for jacking and reshipping the bridge section, the bridge section falls on a sliding shoe comprising the jack, and then the bridge section slides to an installation position along the slide way beams to be adjusted and located. The bridge section is transferred to the sliding system from the offshore barge through cooperative operation of the SPMT and the jack hydraulic lifting system, offshore sliding installation of the bridge section is achieved, and the method has the beneficial effects that the method can be suitable for the conditions that the distance between bridge piers is small, obstacles exist in a ship entering path, and floating installation cannot be achieved; the flexible adjustment of the mounting posture of the bridge section and the accurate alignment of the bridge section and the piston shoe of the jack can be realized through the SPMT; by means of the SPMT and the jack hydraulic lifting system, the influence caused by barge shaking due to tide water changes and waves can be reduced, and the bridge section can be conveniently transferred to the fixed sliding system from the marine barge.
本发明公开了一种基于SPMT和千斤顶的海上桥段滑移安装方法,由驳船运载SPMT及桥段到达桥墩延伸出的滑道梁之间,使用SPMT对桥段进行顶升,倒运并落于包含千斤顶的滑靴上,之后沿滑道梁滑移至安装位置进行调整落位。通过SPMT和千斤顶液压升降系统协同作业将桥段由海上驳船转移到滑移系统上,实现桥段海上滑移安装,其有益效果为:本申请可适用于桥墩间距较小,进船路径存在障碍,无法浮托安装情况;通过SPMT可实现桥段安装姿态的灵活调节和与千斤顶滑靴的精确对位;通过SPMT和千斤顶液压升降系统可以减少潮水变化和波浪导致驳船晃动带来的影响,便于桥段从海上驳船转移至固定的滑移系统上。
