Steel trestle capable of resisting torrent in flood season and construction method of steel trestle
The invention provides a steel trestle capable of resisting torrent in flood season, which comprises a steel trestle, a steel pipe and an anchoring device, one end of the anchoring device is anchored on a steel support, and the other end of the anchoring device is anchored underwater together with the lower section of the steel pipe and a pipe sinking hole through concrete. The steel pipe upper section can be recycled after construction is completed, the occupied time of turnover materials is short, the parallel connection of the trestle steel pipe piles can also serve as a force transmission structure of an anchor beam, and the overall use cost of the flood-fighting structure is low. Constraint connection of the anchoring device is reliable, the whole anchoring structure has the friction pile property, a rock stratum fully participates in stress through a reaming structure to provide effective constraint, meanwhile, the self weight of an anchoring body provides the constraint effect of resisting design flowing water loads, and the construction method is slightly influenced by geology and terrains and is suitable for large-scale popularization and application. Compared with a traditional flood-fighting structure stress component, the problem that a pressing rod is stable when a long steel pipe is pressed is solved, adaptability is higher, and the material utilization rate and the turnover rate are increased.
本发明提供一种抵抗汛期急流的钢栈桥，包括钢栈桥、钢管、锚固装置，锚固装置的一端锚固在钢支座上，另一端通过混凝土与钢管下段以及沉管孔一同锚固在水下。钢管上段在施工完成即可周转回收，周转材料占用时间少，且栈桥钢管桩的平联可兼做锚梁的传力结构，抗洪结构总体使用成本低。锚固装置的约束连接可靠，整个锚固结构具有摩擦桩性质，利用扩孔构造使岩层也充分参与受力提供有效约束，同时锚固体自重也提供了抵抗设计流水荷载的约束作用，其施工方法受地质、地形影响较小，相对于传统抗洪构造受力构件规避了长钢管受压的压杆稳定问题，适应性更强，且提高了材料利用率、周转率。
