摘　　要：简述了在邯郸市集中供热管道工程中 ,应用导向钻进非开挖地下管线施工技术穿越中华大街 ,铺设 72 0mm无缝钢管 (内含 3 2 5mm无缝钢管 ) ,铺设双排 3 77mm(内含 2 19mm无缝钢管 )钢制螺旋管获得成功的实例 ,以对今后同类工程实践提供参考。This thesis introduces the application about new installation of the guided boring trenchless technology on the course of construting the engineering of central heating through zhong hua street of han dan city.For example,We have already greatly succeeded in using the technology,laying out 720mm dan(including 325mm dan),laying out double 377 mm dan(including 219mm dan)and these examples can be used as reference for te similar projects in the future.
