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.
Claims10
A device for making a hole in the ground, comprising:
- a drilling head having a body, said body including a passage and a venturi and wherein rinsing fluid passes through said passage and said venturi;
- means, mounted on said body, for loosening the ground;
- a first pipe through which pressurized fluid passes, said first pipe being connected to said loosening means and providing pressurized fluid thereto;
- a second pipe through which rinsing fluid passes, said second pipe being connected to said passage;
- a protective casing surrounding said first and second pipes, thereby creating a bundle of pipes;
- and
- a fluid motor which drives said loosening means;
- wherein said venturi receives rinsing fluid from said second pipe thereby creating a suction effect which evacuates, via the passage, rinsing fluid from the hole together with the loosened ground.

A device for making a hole in ground, comprising:
- a head having a body with a front end;
- a venturi mounted in said body, said venturi having a central passage;
- channels through which driving fluid passes, said channels ending in said central passage;
- a turbojet mounted at said front end of said body;
- a bundle of first, second, and third flexible hoses;
- and
- a flexible protective casing surrounding said bundle and holding said bundle together;
- wherein said first hose is a high-pressure hose connected to the turbojet to provide high pressure fluid thereto, said second hose is connected to said central passage, said third hose is connected to said channels to provide driving fluid thereto, and driving fluid is provided to said venturi via said channels, thereby creating a suction effect so that loosened ground is removed from said device.
