斜拉桥主塔防腐涂装防护棚的设计和施工

Design and Construction of Anticorrosion Coating Shed for Main Tower of Cable-stayed Bridge

结合礐石大桥主塔防腐涂装工程,阐述了防护棚架的设计与施工工艺,通过对防护棚建模计算分析发现防护棚架的设计安全可靠。防护棚安装完后不影响桥面正常通行,施工速度快,周期短,安全便捷,较好地解决了主塔防腐涂装施工带来的桥面行车安全问题。

Combined with the anti-corrosion coating project of the main tower of the Queshi Bridge,the design and construction technology of the protective scaffold is described.Through the calculation and analysis of the protective shed modeling,we find that the design of the protective scaffold is safe and reliable.It will not affect the normal passage of the bridge deck after the protective shed installed.The construction speed is fast,the period is short,and it is safe and convenient.It better solves the bridge deck driving safety problem caused by the anti-corrosion coating construction of the main tower.
