摘要: Horizontal directional drilling (HDD) is considered as the most applicable and cost effective technology among trenchless technologies known. HDD can be applied in different soil conditions, for deep laying of pipeline diameter long drives. From 12 units manufactured 1984, about 32,135 were sold 2011. Studying productivity first goal this case study. Using cyclic nature operation, determined by applying MicroCYCLONE simulation. Also, operational project estimated. Through current research, presenting resources another that was achieved terms human mechanical resources.
