Apparatus for drilling into hard groundThe invention concerns an apparatus for drilling trenches (42) in the ground\ncomprising a frame (14), a drilling assembly comprising a horizontal support\nplate (18) connected to the lower end of the frame, said plate supporting\ndrilling tools (24, 26...
You will find concrete walls in basements or you may even need to fasten something down onto a concrete floor. Core Drilling into concrete is difficult because the embedded aggregate in concrete makes it dense and hard, and these stones are obstacles to any drill bit. Drilling into concrete ...
Otherwise, differential pressures can be developed above and below the auger that can cause instability of the walls of the shaft and result in a cave-in. Sometimes the rock is too hard to be excavated by a rock auger. Under these conditions, a core barrel can be used for excavating the...
Whether you require channels in walls or floors (chasing), large amounts of materials removed through wall and floor sawing, concrete cut into a particular shape with wire sawing, or openings with temporary support systems, we are sure to have the service to meet your requirements with our ran...
A dual walled pipe string structure defines an annular cavity between the walls into which hard granules may be packed to oppose wall collapse when inserted to high pressure well depths. Segments of pipe thus constructed will reduce the heat transfer across the pipe string allowing for the ...
“I just wanted to pass along how happy I was with Keith’s, and his team’s, performance on my project in Los Angeles last week. Access was the most difficult that I’ve encountered in my 30+ years of fieldwork, with fractions of an inch of space between the rig and walls/equipmen...
This strategy uses the penalizing strategy to transform problems with constraints into a problem with no constraint. Repairing strategy: In this strategy, infeasible solutions turn into feasible solutions. Preserving strategy: In this strategy, specific operators are used to gener...
Concrete coring is the process of drilling perfectly round holes through hard structures such as concrete walls. It’s the go to concrete drilling technique when a precise circular penetration is needed. With coring, holes up to 60" in diameter can be drilled to virtually any depth. It can ...
There are three main types of caisson drilling: open caissons, drilled shaft caissons, and floating caissons. Open caissons are mainly used in marine construction and are open at the bottom, allowing water or soil to flow through during installation. Drilled shaft caissons are drilled into the...
The penetration is carried out by drilling through roofs and walls. The drive power of the drilling mechanism is drawn from the fire extinguishing medium by converting the latter's hydraulic energy into rotation energy. The conversion can be carried out by means of a propeller/tubular turbine ...
