The slot was very good that day.

Slotting is a groove in which conduit is placed on the wall and ground according to the design drawings in hydropower reconstruction construction. Slotting can also be regarded as breaking ground. You can choose an auspicious day according to the calendar.

Slotting method:

1. After communicating with the construction personnel, start the construction by improving the water quality. Draw a line with ink lines first, and outline the route that needs to be taken (it can be seen from the route map that it is horizontal and vertical. If there are different opinions or changes at this time, you can also discuss with the master). These preliminary preparations will take about an hour.

2. After finishing the line, it is to open a dark groove. Use a special tool cutter to cut the grooved surface according to the line cutting, and then use an electric hammer to cut the groove. In addition, it should be reminded that in some communities, there are many and thick steel bars in the load-bearing walls, so it is impossible to cut off the steel bars (affecting the quality of houses), and only shallow (thickening cement is needed when sticking bricks) or taking exposed pipes, or bypassing other walls.
