超宽混凝土桥面三维激光摊铺机应用研究

Research on the Application of 3D Laser Paver in Super-wide Concrete Bridge Deck

桥面混凝土铺装层是桥梁整体结构中的重要部分,桥面混凝土铺装质量直接影响桥面交通工具的运行舒适度及安全性。文章以G5京昆高速公路跨绵盐路大桥为研究对象,采用三维激光摊铺机进行桥面铺装层施工,首先阐述了三维激光摊铺机的原理,随后详细介绍了桥面铺装施工工艺,并通过与传统三滚轴对比,总结了三维激光摊铺机的应用优势。

Bridge deck concrete pavement is an important part of the overall structure of the bridge.The paving quality of bridge deck concrete directly affects the operation comfort and safety of vehicles on the bridge deck.This paper takes G5 Beijing-Kunming Expressway Bridge across Mianyan Road as the research object,and uses the 3D laser paver for bridge deck pavement construction.Firstly,the principle of the 3D laser paver is expounded.Then,the construction process of the bridge deck paving is introduced in detail.Compared with the traditional three rollers,the application advantages of the 3D laser paver are summarized.
