River-crossing construction device for large-span basket type steel arch bridge heavy tie bar
The invention relates to a river-crossing construction device for a large-span basket type steel arch bridge heavy tie bar, and the device comprises an anchoring structure, a tensioning end structure,a tensioning machine tool, longitudinal steel strand stressed frameworks and safety passage accessories, wherein the plurality of longitudinal steel strand stressed frameworks are additionally arranged into the anchoring end structure one by one from an arch foot area on one side of a main arch, and are pulled to the tensioning end structure additionally arranged in an arch foot area on the otherside of the main arch, after special anchorage devices are installed at the two ends of each steel strand of the longitudinal steel strand stressed framework, tensioning operation is conducted at thetensioning ends through the tensioning machine tool, the multiple steel strands are made to reach the approximately horizontal state after being tensioned, and a parallel longitudinal stressed framework with a certain width is formed. The safety passage accessories are laid on the parallel longitudinal stressed framework to form a passage with an operator passing function. The construction deviceis reasonable in structure, the construction process is safe and reliable, construction is convenient, the erection period is shortened, the construction quality is improved, and the construction cost is saved.
本发明涉及一种用于大跨度提篮式钢拱桥重型系杆过江施工装置，包括锚固结构、张拉端结构、张拉机具、纵向钢绞线受力骨架、安全通道附件，若干根纵向钢绞线受力骨架逐根从主拱一侧拱脚区加装到锚固端结构中，并牵引到主拱另一侧拱脚区加装的张拉端结构中，所述纵向钢绞线受力骨架的钢绞线两端安装专用锚具后，在张拉端利用张拉机具进行张拉作业，使多根钢绞线张拉后分别达到近似水平状态，形成有一定宽度的平行纵向受力骨架，所述平行纵向受力骨架上铺设安全通道用附件，形成一条兼具作业人员通行功能的通道。该施工装置结构合理，施工过程安全可靠，施工便捷，架设周期缩短，提高施工质量，节约施工成本。
