Good afternoon, dear guests!
I'll start with a little background ...
A citizen of Uzbekistan has been living with his parents in the country for more than 12 years. Lives without any payment for housing, at the same time protects the territory and helps to maintain order, as well as makes minor repairs. In fact, I have already become a good friend of our family.
So, from time to time, I ask him to help me with the construction in difficult situations for me, when I really need two additional hands, which, unfortunately, I cannot always find quickly.
This happens infrequently, since the parents' dacha is located 40 km away. from my house and, as a rule, it is costly for me to bring and take it, because it turns out a total of 160 km a day needs to be wound, besides, the road there is very tired: potholes and bumps.
About two weeks ago, I started to do the blind area. To have time to finish everything on the weekend, I needed help in moving the rubble and three pallets of the curb from the unloading point to the installation site, and that's when I asked a person I knew for help.
When I dug a trench for installing a hidden blind area and laying a profiled membrane, I heard a question in my address:
- Are you going to ram?
I answered yes, of course, and asked a counter question: "Why did you ask?"
The Uzbek shrugged his shoulders and said:
- When you start, call me, I will show you how to make a very solid foundation that even an elephant won't push!
I laughed, and his accent added fuel to the fire. What's new here, ramming like ramming? But, nevertheless, I remembered his phrase.
In the first half of the day, I was busy with earthworks around the perimeter of the house and I will open the geomembrane, which I had previously rolled out for measurements, so that there were no extra short cuts left:
After lunch, before laying the membrane, it is time to compact the soil. I call Borya (that's what I call him, and in Uzbek - Botir). Well, tell me, I say, super way ...
I confess I didn't expect ...
So Botir's advice:
First: the loose fertile soil layer must be removed, which I did.
Second: it can be compacted both with a homemade device and with a vibrating plate. Crushed stone is taken at the rate of 1 bucket per 3 square meters of soil and is evenly distributed over the surface. The thickness of the backfill is approximately equal to two fractions of the available crushed stone, so that the soil can be seen through it.
Third: crushed stone is carefully rammed into the ground in any available way:
Done!
What do we get in the end, you ask?
I apologized to Botir for my laugh. It would seem a very simple operation, but... Under the influence of repeated blows, the crushed stone is evenly distributed and penetrates the soil. We get an incredibly solid foundation with effectivepinpointsealing. Each stone compresses the soil underneath, making it very dense, which is unrealistic to achieve without rubble. Don't believe me? Check it out! And see for yourself ...
It is important not to pour a thick layer, otherwise the crushed stone will not give a good compaction. There should be direct contact between the rammer and the stone pressed into the ground, which is achieved only with a thickness of 1-2 fractions.
Now, this plane can carry much higher static and dynamic loads.
If it is planned to pour the foundation, then two passes are made along the base: once they went through a tamping, they poured crushed stone again, then they went through a tamping a second time. In this case, we get a very rigid base without any significant cost.
Everything ingenious is simple!
I hope you are not disappointed and the article was useful to you!
