型钢混凝土柱施工的关键技术控制

Construction Technology and Quality Control for Profiled-steel Concrete Pillar Column

结合工程实际,分析了型钢混凝土柱的特点及施工难点,并通过对施工过程的总结,形成了相应的施工技术和质量控制方法,包括型钢混凝土柱梁柱节点的深化设计、预埋件安装质量、型钢柱的吊装与垂直度监测技术以及钢筋安装质量的控制措施等,在满足设计和质量要求的同时,还进一步提高了施工效率,加快了施工进度。

Due to the geological conditions are more complex karst tunnels and other projects due to tunnel collapse accident.Explore the risk bias of the shallow karst tunnel visual warning technology to horse-port exhaust tunnel project basis,theoretical analysis,formula derivation,field trials and other technical means of influencing factors affecting tunnel collapse probability calculations to determine the critical factors affecting the development of early warning level,hopeing to provide a reference for similar projects.
