管道跨越工程中CAD的应用

Application of CAD in pipeline aerial crossing engineering

本文主要介绍了CAD技术在管道跨越施工中的应用:包括索跨中钢质塔架和主索、吊索的下料和预制,桁跨中桁架的下料和预制。由于CAD技术的应用保证了下料的尺寸精度,提高了施工的效率,高效地解决了管道跨越工程中的很多计算问题。

The application of CAD technology in pipeline aerial crossing engineering are introduced in this paper,which include:cutting and prefabricating of steel tower and the main cable,sling in suspension cable type crossing as well as truss in truss type crossing. It can ensure the dimension precision of cutting,improve the efficiency of construction so as to solve effectively many computational problems in pipeline aerial crossing engineering.
