三维激光投影技术在核电厂施工放样中的应用

Application of 3D laser projection technology in construction layout of nuclear power plants

施工放样作为核电厂建造的关键基础工作,是其他施工活动的依据,其对工程质量及进度有着直接影响。目前核电建安领域主要采用全站仪进行逐点式放样的施工放样方法,该方法具有放样精度差、施工效率低和人工成本投入大等弊端。本文主要提出了应用三维激光投影技术实现核电厂快速施工放样,该方法具有批量放样和投影精度高的特点,通过核电厂施工放样可行性分析和某核电项目现场应用,并使用全站仪进行对比分析,验证了三维激光投影技术在核电厂施工放样中具有一定的应用前景。

As a key foundation work for nuclear power plant construction,construction setting out is the basis for other construction activities,which has a direct impact on the quality and progress of the project.At present,the construction setting-out method of point-by-point setting-out with total station is mainly used in the field of nuclear power construction and installation,which has the disadvantages of poor setting-out accuracy,low construction efficiency and large investment in labor costs.In this paper,the application of 3D laser projection technology is put forward to realize the rapid construction lofting of nuclear power plants,which has the characteristics of batch lofting and high projection accuracy.Through the feasibility analysis of construction lofting of nuclear power plants and the on-site application of a nuclear power project,as well as the use of total station for comparative analysis,it is verified that 3D laser projection technology has a certain application prospect in the construction lofting of nuclear power plants.
