Steel trestle lower structure and rapid installation method thereof
The invention provides a steel trestle lower structure and a rapid installation method thereof, and belongs to the technical field of steel trestle installation methods. The problems that when an existing steel trestle lower structure is constructed, steel pipe piles need to be installed one by one, the installed steel pipe piles need to be cut, inter-pile connecting systems need to be welded between the steel pipe piles, the field welding amount is large, and the welding condition is poor are solved. When the combination comprises one combination unit, one steel pipe pile is lowered after being aligned with the high steel pipe, and the other steel pipe pile is lowered after being aligned with the low steel pipe with the high steel pipe as the axis; when the combined joint comprises at least two combined joint units, the steel pipe piles on one side are aligned with the corresponding high steel pipes and then put down, and then the steel pipe piles on the other side are put down; the combined joints are connected through inter-pile connecting systems. Partial high-altitude operation can be converted into ground operation and can be parallel to foundation construction, the construction quality can be guaranteed, and the construction speed can be increased; and the pre-welded steel pipe is used for positioning, so that the lowering accuracy and verticality of the steel pipe pile can be ensured, and the construction quality is improved.
本发明提供一种钢栈桥下部结构及其快速安装方法，属于钢栈桥安装方法技术领域。为解决现有钢栈桥下部结构施工时需要逐个安装钢管桩，安装后的钢管桩需要切割并在钢管桩之间焊接桩间联结系，现场焊接量大，焊接条件差的问题。当组合联中包括一个组合联单元时，一个钢管桩与高钢管对准后下放，以高钢管为轴将另一个钢管桩与低钢管对齐后下放；当组合联包括至少两个组合联单元时，将一侧钢管桩与相应高钢管对齐后下放，再将另一侧钢管桩下放；组合联之间通过桩间联结系连接。可将部分高空作业转为地上作业，能与基础施工平行作业，能保证施工质量，加快施工速度；使用预焊接钢管进行定位，能够保证钢管桩下放的精准性和竖直度，提升施工质量。
