it’s needed to make perfect holes in rocks and concretes. there are both dry and wet drilling methods that are used according to the surface. the hydraulic and electric core drilling methods are commonly used in construction sites. the hydraulic method is used when large and deep holes are needed in a concrete surface.
on hard concrete, soft-bonded diamonds will work best, while hard-bonded diamonds are recommended for softer surfaces. since some experimentation may be necessary at the start of a project, your concrete grinding contractor should be prepared with a variety of grit sizes in three or more different bonds to determine which combination will work best for your needs.
specialized equipment for the underwater inspection of steel and concrete waterfront structures is described. this includes a high-pressure waterjet cleaning system for steel and concrete structures; improved underwater inspection equipment for collecting quantitative data on concrete structures; and a new underwater steel inspection system that accurately measures the thickness of corrosion pitted
hold the rebar locator flat against the concrete and turn it on. start along the edge of the concrete so the locator handle points down. press the back of the locator firmly against the concrete. press the power button on the front or side of the locator and wait for the display to come on.
today, reverse circulation is the preferred method for initial exploration, ore body development and in-pit grade control. the technology has gained ground for its speed, efficiency and ability to provide accurate samples for evaluation by geologists. we, at epiroc, continue to drive the development of new and improved technologies.
surface penetrating radar (spr) is a recently developed technology for non-destructive testing. it can be used to image and interpret the inner structure of the reinforced concrete. this paper gives the details about a compact and handheld spr developed recently for reinforced concrete
ring saws are small in size while still offering a significant amount of power needed to make cuts. they can typically make cuts of up to 275 mm deep. they are used for making cuts in the most confined places with a lot of precision. these saws are known for their clean cutting experience in that they are used with water to keep the blade cool.
concrete cores (with ~10cm diameter) were obtained from the bridge and tested in laboratory (figure 4a). schmidt hammer assessment of compressive strength was also assessed at 24 distinct locations. cracks were marked with a felt pen and photographed, whereas a set of representative crack widths were measured with a handheld usb microscope veho
excavation of the ground within the tunnel bore may be either semicontinuous, as by handheld power tools or mining machine, or cyclic, as by drilling and blasting methods for harder rock. here each cycle involves drilling, loading explosive, blasting, ventilating fumes, and
