I decided to make pillars with my own hands so that the fence would cost 4-6 times cheaper. I tell you what came of it

Hello, friends.

We have a lot of raspberries on the site. The tapestries for her were once made of wood. It's time to change. In addition, they decided to fence the site around the perimeter with a grid. As you understand, you need a lot of pillars - they began to think how you can save on them.

Finding something suitable at the metal reception is not realistic. In our raspberry region, used ear tubes are a running material. It seems to me that a brilliant idea came to my mind.

What if you take a HDPE water pipe and fill it with concrete? The plastic shell will act as a permanent formwork and reinforcement at the same time (they are making fiberglass reinforcement now). The concrete will act as a rigid core. No sooner said than done. I went to do it.

For the experiment, I took a HDPE pipe with a diameter of 32 mm. It costs about 35 rubles per square meter. Steel pipes of commensurate cross-sections cost 150-200 rubles per meter. In this case, the steel pipe must be painted, and corrosion is not terrible for plastic.

I bought a HDPE pipe and several sewer clamps at a hardware store.

Disassembled the clamps. I used half the clamp for each attachment point. Marked a straight line on the OSB trim. He screwed a pipe along it. I put the clamps every 50 cm. The pipe became straight, without a hint of kinks.

I didn't buy a bag of cement for the sake of this experiment. Used the remnants of tile glue. I don't think that in this situation it will be able to drastically change the result.

He hammered the pipe well with mortar. So that he fills the entire volume, he carefully pierced and tapped (“vibrated”) the pipe. To prevent the solution from flowing out from below, I installed the entire structure on the ground.

He carefully transferred the entire structure to the shade and left it to gain strength for a week.

What can I tell you? The fakir was drunk and the trick failed. The pipe, of course, has become a little harder. But she does not even come close to playing the role of a pillar.

I understand that the cross section is small. I understand that placeholders are needed. But even if you take a pipe with a diameter of 50 mm and prepare a mortar using aggregates (fine gravel or granite screenings), the economy of the whole event will suffer greatly.

As the people say: about the old woman there is a n * rnukha.

If you have experience in pouring pillars (for example, with a rectangular section in formwork), please share it will be useful. Do you know where, in addition to metal reception, you can get used ear pipes - also write.
