How to make a homemade drill for drilling wells for soft
For drilling shallow wells in soft ground, you can use an improvised tool. At the same time, the maximum depth of the barrel can be no more than 20 m. You can make it with small skills in working with the welding machine.
Design
- One of the structural elements is a detachable drill pipe. Its length will increase with increasing depth of the well.
- The next important part is a handle that allows you to rotate the pipe with your own hands or with an assistant through physical effort.
- The main element of such a hand tool is a drill, which can be manufactured in several ways.
Tip: decided to make a drill, which you can drill homemade wells for water yourself, be sure to use metal. In this case, you must have skills in working with welding equipment.
Making the drill yourself
Below is a guideline of the tested design. Follow the safety instructions when working.
The simplest option is a spiral auger, for which a metal rod is selected, the end of which is well sharpened. To do this, pull back 200 mm from the tip of the tip and weld 2 knives..
You can make them from the halves of a steel disk with a diameter of 100-150 mm. Weld the knives to the metal rod at a slight angle, no more than 20? to the horizontal, placing the halves opposite each other. The total angle between them will be 40 ?.
Well sharpen the cutting edges of the manual drill, then the process will occur quickly and without difficulty.
By the way, in the manufacture of a spiral drill at the factory, use special tool steel. It is first heated, and then twisted into a spiral and hardened. In this case, the step of the spiral turns equals their diameter.
The working process
From the rotation of the handle, the homemade tool begins to cut into the soil layer with pointed knives. Then you need to pull it together with cut soil up. The earth is poured away from the place of drilling a well, for example, in a wheelbarrow, so that it can then be removed from the site. Then the procedure is repeated again.
As the homemade water well will increase its depth, produce an increase in the tool bar. Fix the main elements to each other with a threaded or sleeve connection.
To insure against separation of components, secure them additionally with cotter pins. When lifting an elongated tool to the top, remove the additional links of the rod.
Tip: use a spiral drill for clayey soils or with fine gravel that gets in the way of it deep into the well.
Spoon type drill design
If the soil is resistant to crumbling, for example, loam, wet sand, it is better to use borax spoons. You can make it yourself from a cylinder, in which you need to make a longitudinal slot in the side surface.
It happens that its shape can be spiral. The length of the spoon-spoon traditionally does not exceed 700 mm.
Inside the recoverable rock is held up by compression and adhesion. Therefore, for more granular soils used a narrow slit in the tool.
You can make a cylinder out of sheet steel, which must be rolled according to a given diameter. You can take a suitable piece of metal pipe, which initially has a cylindrical shape.
During operation, the spoon removes the soil with horizontal lower edges and a vertical edge. Clay, sand accumulates inside the cylinder. Sometimes you can weld a simple metal drill at the bottom, but it should be located strictly along the axis of the rod.
The peculiarity of the tool is that if the axis of the rod and the drill coincide, then the line of the axis of the body, together with the cutting edge, is displaced by 1-1.5 mm relative to it.
Due to this mutual arrangement of the axes, the tool can drill a hole of a larger diameter than that of itself. This is due to the removal of soil from the side walls of the well, due to the longitudinal cutting edge. Periodically it is necessary to lift the tool upward for cleaning.
Be aware that the spoon drill normally passes through the casing, which is set to prevent the collapse of the well shaft.
Is manual drilling profitable?
Its advantage is:
- low cost of works;
- the use of a hand pump during a power outage;
- preservation of the landscape in a suburban area, since special drilling equipment will not drive into it.
Disadvantages:
- well depth restriction;
- inability to use in dense soils.
To use home-made drills can not only for the manufacture of wells. They performed well when installing fences, installing columnar foundations, planting plants and for other garden and construction works. From the above it became clear that to make such an “assistant” is possible under the power of any owner of a private house, if there is a suitable tool and some skills to work with him.
Conclusion
When on a country site the ground is soft, you can drill a water well with a simple homemade tool. For its manufacture you need a material that will always be found in the household, as well as a welding machine.
The drill can then be used for other work on the site. In the presented video in this article you will find additional information on this topic.
