Railway-crossing bridge jacking construction method
The invention relates to the field of jacking construction of railway-crossing bridges, in particular to a railway-crossing bridge jacking construction method which comprises the following steps: S1, construction preparation; s2, a jacking foundation and a column embracing beam are constructed; s3, a jacking system is installed; s4, test jacking is carried out; s5, pier column concrete is cut; s6, jacking to a designed height in a grading manner; s7, bridge pier heightening; s8, a support is replaced; s9, beam falling; and S10, dismantling the temporary facilities and equipment. According to the multi-connected continuous beam slope adjusting jacking construction method, by improving the construction technology of bridge jacking, the construction deviation of bridge jacking in the bridge jacking construction process is further reduced, meanwhile, the safety and stability of bridge jacking construction are further improved, and the method is a multi-connected continuous beam slope adjusting jacking construction method; by means of the method, the gradient of the bridge can be automatically changed in the jacking process, the overall posture of the whole bridge is adjusted, it is guaranteed that the length of an expansion joint is not affected by the change of the extension length of a beam body, and the accuracy and safety of in-place jacking of the bridge are guaranteed to the maximum extent.
本发明涉及跨铁路桥梁的顶升施工领域，尤其是涉及一种跨铁路桥梁顶升施工方法，包括以下步骤：S1、施工准备；S2、顶升基础和抱柱梁施工；S3、安装顶升系统；S4、试顶升；S5、切割墩柱砼；S6、分级顶升至设计高度；S7、桥墩接高；S8、更换支座；S9、落梁；以及S10、拆除临时设施和设备。本发明通过改进桥梁顶升的施工工艺，使得桥梁顶升施工过程中的桥梁顶升的施工偏差得到了进一步的降低，同时桥梁顶升施工的安全性和稳定性得到了进一步的提高，且本发明为多联连续梁调坡顶升施工方法，通过此方法使桥梁在顶升过程中能自动变化坡度、调整全桥整体姿态，保证了梁体伸长长度变化不影响伸缩缝的长度，最大程度保证了桥梁顶升到位的精确性和安全性。
