| Abstract: | The trenchless horizontal drilling machine is essential machine of trenchless technology,it relates success or defeat of project. As important components of trenchless horizontal drilling machine, Drill bits play an important part in guidancing, enlarging hole and cleaning hole. The choice of drill bits are related to difficult extent of follow work.So it is necessary to choose a suitable drill bit as geology and engineering requisition.This essay detailed the types and compatible analysis of trenchless horizontal drilling machine. |
