As you can see it is a fairly simple project and one that we hope to point a few pointers out for anyone who may be seeking core drilling information.
First you must secure the core drill to the concrete surface. We typically choose to use concrete wedge anchors for this purpose because of their strong grip.
You can see that the concrete surface of the pipe is not flat so we had to use some wood wedges to level up the base of the core drill rig so it would cut the hole properly.
Notice that our core drill rig is mounted at a 180 degree angle to the hole being drilled. This was necessary to keep the drill rig in line with the hole. We use a cordless impact wrench to tighten up the wedge anchor nut which secures the core drill rig base to the concrete pipe. It is always useful to have a 12" or larger adjustable wrench handy to further tighten up the wedge anchor nut. When we have the drill bit centered on the mark we then install a second wedge anchor to keep the drill from moving.
This is the pipe after we have removed the core machine and cleaned up the project. Notice how the holes are perfectly aligned with each other.

This really seems like an intricate process. Something that really stands out is the fact that there is so much water that is needed. It does make sense though, with the water being able to keep the drill cool. This really is great information to have, thank you for sharing. http://www.walsercontracting.ca/en/
ReplyDeleteI loved and appreciated how there were images that went along with the explanations of core drilling. This post makes the process seem really simple. However, I'm not entirely sure if it is or not. http://www.mastercutconcrete.com.au/services
