Integral dragging construction method for steel box basket arch bridge with arch
The invention relates to the technical field of bridge construction, and discloses an integral dragging construction method for a steel box basket arch bridge with an arch, which comprises the following steps: S1, construction before dragging, S2, trial dragging, S3, formal dragging, and S4, in-place beam falling. Dragging construction is adopted, traction force comes from the hydraulic dragger, cantilever traction and dragging can be achieved under the condition that a balance weight exists, the temporary buttresses can be arranged according to the minimum number according to anti-overturning checking calculation and the balance weight condition, investment is reduced, the construction period is shortened, and compared with segmental hoisting and arched beam separated hoisting needed by bridge site assembly, the construction efficiency is greatly improved. By means of integral dragging construction, the working procedures are greatly reduced, the safety risk is reduced, and the construction period is shortened; the sliding shoes are adopted to improve the installation precision, and the problem that a jack is frequently adopted for transverse deviation correction in a walking type incremental launching construction method is solved; the construction method is short in construction period, low in cost and excellent in technical performance, has safety guarantee and effectively improves the construction efficiency of the bridge.
本发明涉及桥梁施工技术领域，公开了一种钢箱提篮拱桥带拱整体拖拉施工方法，包括以下步骤：S1、拖拉前施工，S2、试拖拉，S3、正式拖拉，S4、就位落梁。本发明采用拖拉施工，牵引力来源于液压拖拉器，可在有配重的情况下悬臂牵引拖拉，使得临时支墩可根据抗倾覆验算及配重情况按最少数量设置，减少了投入，缩短了工期，相较于桥位拼装所需要的分节段吊装、拱梁分开吊装，本发明整体拖拉施工大大减少了工序，降低了安全风险，缩短了工期；本发明采用滑靴提高安装精度，避免了如步履式顶推工法频繁采用千斤顶进行横向纠偏的问题；本发明工期短、成本低、技术性能优且有安全保障，有效提高了桥梁的施工效率。
