How well is drilled

For drilling wells the price varies depending on the soil and the depth of the water and starts from 4 thousand rubles per meter. Of course, the work can be done independently, but this requires knowledge and special tools. The location of the well must be perpendicular to the flow of groundwater. If the soil is characterized by a dense and dry structure, the process can be simplified by the periodic addition of 2-3 liters of water. As a rule, a spoon drill is used, but for coarse and viscous rocks, the serpentine tool is the best option. It should be noted that the drilling of the well at the last stage is always performed by a spade drill, regardless of the unit used earlier.

What does the cost depend on?

The main factor of pricing is the depth of the digging, which depends on the occurrence of the aquifer. That is, the further it is located from the surface, the more expensive drilling and more materials are used. The complexity of the work affects the type of soil on the site. Rocky dense soil complicates the task, while the digging of soft ground passes much easier.

There are two methods for creating a well:

• Drilling a well with a machine;
• Handmade digger.

The depth of occurrence of the aquifer is the main determining factor in the selection of the method.

Facing

The inner surface of the mine is lined with various materials, preventing the walls from shedding and the ingress of thawed water. Most often used wooden frame, brick, ring of concrete and stone. Each material has its own characteristics and advantages. For example, brick facing requires a lot of time and effort, and this method is quite dangerous. When using concrete rings, there is a possibility of leakage, but work is much faster. It is also worth noting that the rings in the upper part of the shaft may eventually move, resulting in a change in the soil in the upper layers and the influence of precipitation. As a result, stones and sand fall into the water. In addition to the materials used for the cladding, the means for sealing and strengthening are taken into account in determining the value.

What is included in the process of creating a well

Drilling a well with a machine can include both the whole process of arranging the source of water, and only the pit of the pit, everything depends on the financial capabilities and wishes of the customer.

The list of additional works contains the following items:

• Pumping fluid. First comes dirty water with an admixture of soil. After it is pumped out, you can immediately use a well.
• Creating a blind area. It provides protection from surface water and strengthens the upper part of the mine.
• Filter. As a filtering material, as a rule, gravel and crushed stone are used. The bottom of the well is filled with stones, while their layer should be at least 25 cm.
• Water supply device. For the supply of water, both manual and electrical machinery can be used.
• Building a shed. The erection of the structure is made from selected materials, while carrying out this stage of work is possible for every person.
• Removal of soil. In some cases, there is no application of excavated land on the site, so it is necessary to export it.

Tool

Drilling of the well into the water, depending on the available soil, can be carried out by impact or rotational method, each of which requires the use of different tips. The drill consists of the following elements:

• Swivel - the tip used to control the tool and screwed on the top of the rod.
• Drilling part with tapered thread, worn on the stem clutch. For its manufacture, solid steel is used.
• The rod has a square shape and a thickness of 50 mm.

Drilling a well: features

Ground, crumbling during work, can clog the well. To prevent its collapse, a casing is placed on the drill , the diameter of which substantially exceeds the dimensions of the drill. At the edges of the pipe there is a thread necessary for building up as the well deepens.

To make the drill move strictly vertically, a thick board with a cut hole is installed at the intended location of the well, in accordance with the dimensions of the casing. In the process of building it, the hole gradually expands.

Drilling of the well is performed by various tools, selected with regard to the type of soil. Wet and dry sands require the use of a spoon and a bailer. If the soil contains a large amount of pebbles and gravel, a chisel is added to the chute.

For rocks with high and medium density, the well is drilled using the shock method. It is carried out on a rope or bar. The first option is optimally suited for creating a deep mine. Drilling and pumping machines also became quite widespread . The speed of the digger with their use is 2 m / h, while two people are required to carry out the work.
