摘要
结合海创基地扩建改造项目,系统研究钢桁架空中风雨连廊群的施工关键技术与管理实践。通过BIM深化设计实现多专业协同与碰撞检查,确保构件在工厂高精度预制;现场采用汽车吊与塔吊协同作业,结合临时支撑体系,保障高空吊装安全与精度;施工全过程实施焊缝无损检测,并布设传感器对关键节点进行应力与挠度健康监测。实测结果表明,结构变形与内力均满足设计要求,施工质量受控。本工程实践为同类高空连廊群施工提供了可复制的技术路径与管理经验。
Combined with the expansion and renovation project of the Hai Chuang Base,this paper systematically studies the key construction technologies and management practices for the steel truss aerial weather‑protected corridor group.Through BIM deepened design,multi‑professional collaboration and collision checks are achieved,ensuring high‑precision prefabrication of components in the factory;on‑site,collaborative operations are carried out using mobile cranes and tower cranes,combined with temporary support systems,to ensure the safety and accuracy of high‑altitude lifting;throughout the construction process,non‑destructive testing of welds is implemented,and sensors are installed to monitor the stress and deflection of key nodes for structural health monitoring.The measured results show that the structural deformation and internal forces meet the design requirements,and the construction quality is under control.This engineering practice provides a replicable technical path and management experience for the construction of similar aerial corridor groups.
