非开挖地下管线成孔机的研制

Development of A Trenchless Horrizontal Boring Rig

摘要:

非开挖地下管线成孔机由水平钻机、扩孔机及动力站3部分组成，采用机液混合传动方式。对样机进行了试验，效果较好。该机可用于塑性地层的小口径圆形及非圆形地下单管及管线集束的非开挖铺设施工。

Abstract:

The horrizontal boring rig consists of a horrizontal drill, a hole opening machine and a powerpack with a combined mechanical and hydraulic driving. The trial of the prototype indicates good results. Therig can be used in trenchless case for installation of small diameter circular or non--circular single and group pipesin plastic formation.
