There are different options for installing the bases for the fence. The proposed technology is not easy, but it allows you to get a good end result. If done correctly, the structure will be strong and durable. Thanks to a reliable base, the fence will not react to soil movement, natural and climatic conditions, and air temperature.
Step-by-step instructions for installing a pole
As in any business, the first stage is preparatory. It is necessary to have a 50x50 profile pipe with a wall thickness of three millimeters.
Considering that this is the main part, the support of the entire structure, it is impossible to save on its quality. The length of the pipe needs to be taken three and a half meters.
Using a grinder on the side of the pipe, which will then be dug into the ground, you need to make a small cutout that has a rectangular shape. The length of the cut should be 12 centimeters and the same from the edge. This is necessary so that cement penetrates into the pipe and hardens there. Thus, the pillar, together with the cement block, will become a single whole.
After that, a well is made, in which filling and, accordingly, installation will be carried out. It needs to be made deep enough. A pipe is inserted there and a notch is made.
After that, using a tape measure, measurements are taken, during which we get approximately 156 centimeters.
We measure seventy centimeters deep from the mark and leave a mark with white electrical tape. You can see better that way.
To prevent the pillar from being squeezed out in winter, it is important to carry out concreting with 2 diameters. They are set with a drill (bottom diameter 18 centimeters) and PVC pipes (top diameter 11 cm).
Consequently, from below to the mark made with electrical tape, concreting will be carried out with a diameter of 18 centimeters. After that, a plastic pipe is pushed onto the profile from above and concreting with a diameter of eleven centimeters is made already from the mark. And at the end of all work, a mixture of sand and gravel will be poured from the outside around the pipe.
Before starting the main work, water is removed from the well. She will appear there in 90% of cases. To do this, you can take a very simple device. You can build it from an ordinary plastic bottle, in which a cutout is made on the side, attached to a long aluminum pole.
To align the pillars with each other, you need to pull a special string and be sure to do this on top. The string is pulled from one corner post to another. When sagging, it is required to additionally install stops with nuts welded to them, through which the string is then pulled. With the help of this string and a plumb line, the places where the drilling will take place are set.
A pillar is placed along the string, the straightness of which is set due to the level consisting of 2 planes.
Now you need to concrete everything. Provided that a large amount of water is collected in the well, initially the concrete does not need to be mixed with a very liquid one.
Pour the mixture in portions, after each such portion it must be tamped. A wooden stick is suitable for this purpose. As soon as the first two or three portions of concrete are poured, you need to try to level the post.
Once the concrete has reached the mark, you need to put on a plastic pipe. The profile should be in the center of the PVC pipe.
In order to pour the solution into the pipe as conveniently as possible, it is recommended to make a special gutter. The space around this pillar is filled with a mixture of sand and gravel. It is not necessary to pour concrete all the way to the top. In any case, it will rise during hardening.

Liquid cement mortar is also poured into the column in portions. For convenience, you can take a five-liter bottle and cut off the neck from it. The neck is inserted into the pipe and the concrete is poured in this way.
