a hydraulic hammer with fluidic actuator was manufactured and applied to directional drilling due to the low penetration rate, long construction period and high drilling cost occurred during the operation of horizontal directional drilling in complicated formations, such as hard, fractured and cavy stratum. On the basis of hydraulic percussion rotary drilling technology, the hydraulic hammer has been innovatively designed and applied to trenchless drilling with horizontal directional wells, which is actuated and controlled by a fluidic amplifier. In addition, the actuator was tested in field by various pumped mud with different flow rates. Test results have implied that structure design of the whole drilling tools is qualified, and the pressure loss of fluidic actuator is permissible, which is suitable for the horizontal directional drilling of trenchless engineering project. Therefore, the original design of hydraulic hammer with fluidic actuator has solved the technical problem on horizontal directional drilling in complicated stratum, which has an excellent application value and promoted potential.
