The owner of a suburban or personal plot, if his material possibilities are not unlimited, willfully or not become a jack of all trades. For example, I decided to fence off ten meters with a fence with a net. There is a grid, we need poles. Wooden are short-lived, concrete ~ heavy, about 300 kg, you can’t lift it alone. The place is such that the truck crane will not drive up, and it’s expensive to hire workers because of 4 pillars. So I decided to make the posts myself.
As a formwork, I used two-meter thick-walled plastic pipes with a diameter of 150 mm, sawing them along. Then he put the halves together and fastened with wire. At the junction of the halves, I drilled 2 holes from the bottom, in the middle and from above for the mortgages (wire with a diameter of b mm), to which the grid will be attached. An ice-drill (180 mm in diameter) drilled 180 cm deep holes in the intended place. To do this, I had to remove the handle from the ice drill and extend it with a 1.5 meter pipe. He drilled pits beneath the pillars with sand and fine gravel so much that their depth was about 140 cm (in our area, the depth of freezing of the soil is 120 cm). A reinforcing rod hammered into the center of each pit. Cement grade 500, sand and gravel was taken in a ratio of 1: 2: 3 and made a solution in a home-made concrete mixer. The prepared solution was poured into the pits, rammed with a metal pipe after every 4 ~ 5 shovels of the poured solution. So gradually the pit filled. Then he put the halves of the pipe fastened with wire onto the reinforcing rod and installed it on the freshly poured solution vertically in level, with mortgage holes in the direction of the fence, and aligned it with the cord so that the posts stood strictly in line. He fixed the pipe in this position with the help of stakes previously hammered around the pit. Then he put a stepladder next to him and carefully put the solution into the pipe. Having poured a solution of 30-40 cm, he rammed it again. Filling the pipe with the mortar to the first hole for the mortgages, inserted a 6 mm wire into it and continued to fill the pipe with mortar. So he filled it to the desired column height - 1.5 m. A week later he removed the wire holding the 2 halves of the pipe and removed them. In front of me was a pretty decent, smooth, strong pillar.After all the poles were ready, he pulled a steel cable through the mortgages and secured the net to it.
