Installation of lighting poles may begin only after obtaining permission for laying electric cables as in the works there is a great risk of damaging existing utilities. To do this you must create a project which would take into account all the factors such as the topography required illumination power of the lamp wire and the total length of line and submit it to the relevant authorities.

After approval of the project in the designated area with the help of a level and mark the location of the masts or supports. You can now proceed to the preparation of trenches for laying cable. If you plan to use armored cable then the prepared depth of the trench should not be less than 800 mm from the surface of the earth. In the case of the use of power cable, this value increases depending on the surrounding terrain up to 1250 mm. the trench is laid a sand layer with a thickness of about 150 mm and carefully shed water. After this, the sand must be compacted before a layer of 100 mm.
Now you can start preparing the ground where you plan to install lampposts. For that, prepare a square hole 1000x1000 mm and a depth of 1200 mm in the center of which proveryaetsya hole depth of 1000 mm and a width equal to the diameter of the support is increased by 100 mm.
And concrete and steel lighting poles after installation in the pit definitely filled with concrete. The solution should fill the hole and the entire hole to a height of 200 mm to form a concrete slab holding the prop. Fully pit
