DHD1120 Water Well Drilling Down The Hole Hammer With High
Environmental Protection
Product description
High Pressure DTH hammer DHD1120 is very popular in international
mining drilling and rock excavation field.
Product introduction:
Sollroc's DTH hammer consist of only two moving parts: the piston
and the valve. With so few moving parts, the smart solution
delivers reliable high performance drilling in the most challenging
conditions. Water, at up to 180 bar delivery pressure, is used to
power the impact mechanism of the hammer at a high frequency rate.
When the water leaves the hammer, it loses the pressure and keeps a
low flush velocity. This however is still adequate to bring any
cuttings to the surface and clean the borehole. Additionally, the
hydrostatic column, which is created above the hammer, helps to
keep the hole stable while preventing potential collapse. This also
prevents water from being drawn into the borehole, which increases
hole stability and prevents potential environmental issues.

Sollroc produces the most efficient drilling hammers (DTH), built
for the most diverse applications: water drilling, construction,
mines etc. Our technology and unique design gives to our drilling
hammers high performance, in various types of formations.
Application
Sollroc offers a wide range of high performing drilling equipment
designed for percussive drilling. In fact, we offer the most
productive DTH hammers in the world. DTH drilling as a method is
growing in popularity in both foundation works and in well and
geothermal drilling. As the global redevelopment of urban areas
continues, this trend comes with a challenge - accessing and
drilling in populated areas without damaging the existing
structures around the work site. It is obvious that our customers
in geotechnical operations have very different demands on the
equipment than those working with high production drilling in, for
example, quarrying. The demand for application-tailored solutions
is increasing.
