Construction method of continuous steel plate girder bridge
The invention provides a construction method of a continuous steel plate girder bridge, which is used for constructing a bridge body with a bolt joint positioned between bridge spans, and comprises the following steps: S1, mounting a bridge girder erection machine at a specified position; s2, the first beam body and the second beam body are hoisted to the designated beam falling position at the same time through the bridge girder erection machine for beam falling, and after beam falling is completed, the first beam body and the second beam body are spliced and fixed; s3, controlling the bridge girder erection machine to pass through a hole; s4, hoisting a next beam body to a specified beam falling position by the bridge girder erection machine for beam falling, and splicing and fixing the next beam body with the adjacent erected beam body after beam falling is completed; and S5, the S3 and the S4 are repeated till construction is completed. In the full-bridge construction process, a temporary construction support does not need to be arranged for supporting and fixing the beam body, and the construction cost can be remarkably reduced.
本发明提供一种连续钢板梁桥的施工方法，用于对栓接缝位于桥跨之间的桥体进行施工，包括以下步骤：S1：在指定位置安装架桥机；S2：使用所述架桥机同时将第一梁体和第二梁体吊运至指定落梁位置进行落梁，并在落梁完成后将所述第一梁体和所述第二梁体进行拼接固定；S3：控制所述架桥机过孔；S4：由所述架桥机将下一梁体吊运至指定落梁位置进行落梁，并在落梁完成后将其与相邻的已完成架设的梁体进行拼接固定；S5：重复S3、S4直至完成施工。在本发明的全桥施工过程中无需设置临时施工支架对梁体进行支撑固定，能够显著降低施工成本。
