DTH hammer and three-wall drilling pipe tech

In this technology,the DTH hammer can drill in soil and rock layer for water well and pile hole. In rock, rock weathering, boulder formation, this technology realized 400 - 600 mm diameter and 200m deep water well drilling.

In soil,rock,rock weathering, boulder formation, this technology can realize 3000mm pile hole and 300mm diameter 2000m deep exploratory hole.

Improve drilling efficiency for 3-5 times,save more than half of equipment investment and 40%-60% oil consumption.

For this technology, air supply, air exhausting, and cuttings exhausting are realized separately by three different passages:

when drilling a hole, air supply volume didn’t increase (just keep same like drilling in earth surface) according to the increase of depth, which can reduce equipment investment and oil consumption. 

And exclusive use passage for air exhausting without resistance of cuttings and under waters can improve efficiency of DTH hammer greatly

combined DTH hammer and three-wall drilling pipe. In the middle is a pipe to transmit the air for percussion of DTH hammer. 

And the first annular is used to exhaust to the surface for DTH hammer independently.

 The second annular is normal circulation for mud travels to the bottom of the hole.
