I remember that in the past when home decoration, whether hydropower workers or owners themselves like to do hydropower outside, and then walk along the wall. At that time, there were two main reasons for doing so. One was that the master thought it was easier to do it, and he would save a lot of time. The other was that the owners felt that it was more economical, and in the future, bad words were easy to change.

Later, many people found that water and electricity are directly distributed outside the wall, even if hidden with protective strips, but still damp damage, the most important thing is that it does not feel good. So with the continuous improvement of people's quality of life, they began to like to hide the lines in the wall, which can protect the lines and look good. But one problem is that slotting is slower. If the technology fails to pass, the opening is particularly ugly.

But the teacher around him said that the wall groove is not easy to see, it is completely technical, if you can do according to his method, it will be fast and simple. For example, before grooving is not to rush to groove, but first to drill a row of small holes on the wall with electric drills, while drilling while adding water, this will be easier, and there will be no dust.

After a row of holes are opened, the electric drill is used to cut and connect the holes into a line slowly along the adjacent holes. This will save more effort and look good. After the slots are opened, the line and socket dark boxes are cleaned up. Because the line and socket dark boxes are assembled in advance, it is possible to bury the line directly.

The same is true for the transverse slots and hidden sockets on the wall. Firstly, large diameter drills are used to punch holes in the dark box of reserved sockets, and then small wire slots are opened, so that even if the owners do not want to retain the dark box sockets in the future, the impact is not great.

As shown in the figure below, the teacher relies on an electric drill to complete the whole construction process. Even the socket dark box can be made with an opener of similar diameter, which is very simple.

Teacher said that slotting wiring before dark box, so that the position will be more accurate, will not occur too short or too long wire head, can be completed in one time wiring, very easy.
