Which of us did not fall into trouble with expensive acquisitions? Most likely, it happened to everyone. However, someone just bought aluminum instead of gold, and someone acquired a large plot of land in solitude for such a desired house and received loose sandy rocks instead. How to conduct construction in such conditions we have already said more than once – a fortified foundation, a lightweight house and everything is good again. As for water wells?
Before proceeding with an independent solution to this problem, we advise you to contact a widespread source of information – the Internet. However, reading this, you probably have already done this. What will you find here? First of all, to find out the prices for drilling is much easier, and turning to professionals in this case is the best solution (at least for sure the safest and simpler). The same as armed with the magical “I will do it myself!»We will give only a few tips.
So, loose sandy rocks are drilled with a tin, while using pipes to strengthen the well. In this case, the pipe should go ahead of the face, because the diameter of the tin should be selected 100 mm less than the internal diameter of the column of casing pipes. And to drop a tin from a height of at least one meter, which will ensure the optimal suction of sand. If there is no water in the well, then it is added with calculation 0.1 liter for each flight, if there is water, then the tin is weighed down with a shock bar.
In the case of dry sands, oily clay is discarded into the well, which is then poured with water. Such a mixture will bind the sand and allow it to freely extract it. The sandy rock can be loosened with a spherical harness equipped with a knife. If the sand is characterized by high humidity, then a piston -type harness is used.
And the last advice: do not forget that experts will cope with this work without enduring you.
