We will improve the drill for solid and unavailable clay
In order to build a columnar foundation, you need to drill holes in the ground, into which piles will then be inserted. For these purposes, manual drill is most often used.
The task is not easy. Work requires great efforts and physical training. Particularly complex area – dry clay layer. She is very solid and is badly rejoicing. Not everyone can do such work on their own.
Workers begin to come up with exits from the position: moisten the layer of clay with water, additionally pierce the “axis” of drilling into it, and grind the drill blades. Inventions at times amaze with their diversity. As a result, nothing helps, and the work continues in the same line – with then indignations. But the easiest way out of this situation is to improve your bourgeois. Make it many times more efficient.
The whole secret of the improvement is to cut the end part along the entire axis at the depths of the drill about 15 cm through the drill. All the parts that formed after the cut bend in a spiral. You will get a part of the drill outwardly similar to the drill. This drill will increase the performance of a manual drill, and you can personally feel it.
