Down-the-hole hammer drilling is a technique used primarily for drilling boreholes in hard rock applications. It employs a pneumatic hammer, situated directly at the drill bit, to deliver high-impact blows that effectively break up the rock. This method contrasts with traditional rotary drilling, where the drill bit operates at the surface and relies on torque and weight to penetrate the ground.
The integrated drilling and piling machine is a type of pressure machine for road guardrails, livestock fences, and other steel sheet piling applications. This equipment uses a diesel engine as its driving force and features full hydraulic drill machine gear transmission. It is characterized by being lightweight for transport, high precision in basic piling, durability, and environmental friendliness.
