ABSTRACT:
A device for making a hole in the ground has a drilling head having a body. The drilling body includes a passage and a venturi through which rinsing fluid passes. The drilling head has a mechanism mounted on an end thereof for loosening the ground. A first pipe provides pressurized fluid to the mechanism and a second pipe provides rinsing fluid to the passage. A protective casing surrounds the first and second pipes creating a bundle of pipes. A fluid motor drives the mechanism. The venturi receives rinsing fluid from the second pipe thereby creating a suction effect which evacuates rinsing fluid from the hole together with loosened ground.
