跨越深基坑大跨管桁架累积滑移技术

Accumulation slip technology of large caving truss spanning deep foundation pit

根据秦雍城遗址秦公一号保护大棚钢结构的使用要求和设计特点,详细阐述了对于跨越深基坑大跨管桁架滑移安装关键技术。该技术有效的解决了基坑周边没有大型起重设备站位条件的客观因素,又合理的解决了该种结构的安装问题,保证了施工安全和工程质量,对同类钢结构工程施工起到一定的借鉴作用。

According to the requirement of Qinyong Town site of Qingong one shed protection steel structure and design characteristics,this paper describes the deep foundation pit across large span pipe truss sliding key technology. The technology effectively solved the objective factors that did not have the location of large lifting equipment around the foundation pit,and solved the installation problem of the structure reasonably,ensured the safety and quality of the construction,and played a certain reference role for the similar steel structure construction.
