Continuous rigid frame bridge closure non-ballasting construction device and method
The invention relates to the technical field of bridge construction, in particular to a continuous rigid frame bridge closure non-ballasting construction device and method. The continuous rigid frame bridge closure non-ballasting construction device comprises at least four sets of pushing assemblies and stiff frameworks with the same number as the pushing assemblies. Each pushing assembly comprises jack I-shaped steel and a matched limiting frame. An embedded part A and an embedded part B are pre-embedded in a designated position in advance, and the embedded part A and the embedded part B are both kept in a protruding state; the temporary locking device and the embedded part A are firstly fixed, then the temporary locking device and the limiting frame are fixed, and then the I-shaped steel and the jack are sequentially installed in place; and pushing is conducted through force application of a jack, stopping is conducted after a designated position is reached, the stiff framework and the embedded part B are welded and fixed, and pushing work is completed. According to the method, counterweight equipment and technology are not needed, the closure section can be conveniently and rapidly constructed in transportation limited areas or severe construction environments such as construction of ultrahigh pier bridges in canyons, the construction efficiency is improved, and the construction difficulty and cost are reduced.
本发明涉及桥梁施工技术领域，涉及一种连续刚构桥合龙不压重施工装置及方法包括至少四组顶推组件和与顶推组件数量相同的劲性骨架；每组顶推组件包括千斤顶工字钢以及配套的限位架；预先在指定位置处预埋预埋件A及预埋件B，预埋件A和预埋件B均保持凸出状态；先将临时锁定装置与预埋件A固定住，再通过临时锁定装置与限位架固定，之后依次将工字钢以及千斤顶安装到位；通过千斤顶施力顶推，到达指定位置后停止，将劲性骨架与预埋件B焊接固定，完成顶推工作。本发明无需使用配重设备及工艺，在运输受限地区或者施工恶劣的环境中例如在峡谷中的超高墩桥梁的施工中可以方便快速的对合龙段进行施工，提高了施工效率降低了施工难度和成本。
