Often in the process of repair there are situations when it is necessary to make a hole in the wall. This can be done in various ways, each of which has its advantages and disadvantages. But the selection method still is based on the wall material, as well as the size and type of hole.
The question «burst cast-iron sewer pipe.» — 5 answers
Holes to install electrical cables, electrical equipment, power lines and pipes can be performed mechanically or manually – that is, punching.
To make punching the holes manually, you will need a jumper. Jumper set perpendicular to the wall. Then you need to hit it with a sledgehammer, while is performed around the axis of rotation. We should not forget to periodically clean the holes from dust and chunks of brick.
If you need a rectangular hole, use a jackhammer or a boaster. First beat the top brick and then beat the following. Doing it with a boaster, hammered into a vertical seam.
But still this method is very laborious and time consuming, so it is advisable to use the mechanical method.
At the moment the production is not in place and produced a huge number of pneumatic drilling, electric machines: hammers, screwdrivers and canned. There were opportunities to use a modern tool, having to equip the plates of hard alloy and diamond drills.
Considering the option of drilling with the drill, you need to remember that not every hole can be done with it. It plays the role of the diameter of the hole, the drill does not exceed 50mm, and in some cases 30mm
There is another important point found in the process of drilling concrete by using borax, that’s the rebar in the wall. If the drill hits the metal cutting tool burns immediately. So he can pass tangentially to the fixture and clamps, whereby the drilling stops, and it cannot continue.
A tool called «Carbide crown» implies the ability to make openings have diameters from 50mm up to 450mm.
A possible way to install the adapter, but it can be a few drawbacks: if the size of the crown which is placed on the punch, more than the present, there is a possibility of breakage of the tool; drilling will carry a great danger.
When working lingerie crown has a chance to bump into rebar, in this case, teeth crowns, most likely, broken or blunt. Thin rebar crown can be cut using carbide tipped. And secondly, when drilling the bit you need to consider the depth of bowl crowns.
Of course, you can make a through hole using a core bit for concrete enclosures, while using alternately the crown and the peak of the punch. Ie once You go deep, go to the crown. Then cut the core hole with a spear, and so on, to obtain the desired result. And finally – remember, when drilling concrete with the bits in the room will be a huge amount of dust.
Finally, and most used at the moment, the drilling – diamond. He has a lot of advantages.
1. Versatility. Diamond crown it with concrete and rebar (which is an integral part of concrete structures). Everything is explained very easily: the hardest mineral in nature is a diamond.
2. The design of the diamond crown. Due to its truncatula, the crown gives you the ability to drill holes as deep as you want. You simply drill a solid piece. Thanks to the tubular design, you make the hole clear, and exact diameter, you have no deviation for runout.
3. The opportunity during the work to apply water cooling of the diamond crown. In the process of drilling does not accumulate dust, which largely improves the working conditions and results.
4. Versatility in use. Diamond crown can handle not only concrete, but also brick, granite, granite.
And of course, as everywhere has its disadvantages. Here they are, quite naturally, is the cost of this method. Here you need to consider the cost and of the crown, and the instrument on which it is installed.
