Technology of drilling a well into water by hand, the instruction with video

There are several ways to penetrate the soil in depth. From the point of view of feasibility, the method of drilling water wells, realized by own hands, raises a number of questions, although in some cases it gives a good result and significantly reduces the time for independent well construction. This article will help those who decided to prepare the trunk for further arrangement of the source in this way.

As all areas are characterized by their individual characteristics, it is more advisable to make a brief overview of the recommendations for hydroboring, without generalizing them. The author believes that the thinking reader will figure out what will come in handy and what will not.

Special feature of the

hydrodrilling technology In fact, this is a complex work, in which the processes of direct drilling and softening of soil are combined. The soil is affected not only by the tool, but also by the pressure of the liquid, and the soil is washed out after destruction. The work can be significantly speeded up by adding some abrasive( eg quartz sand) to the pressure water, hunting shot( steel balls) or something like that. This will significantly increase the efficiency of crushing solid segments( beds, pieces) of soil.

Pros

  • The compactness of the equipment, therefore, the ability to drill on a limited segment, without the risk of damage to the constructed area.
  • High speed of technological operations and reduction of their number.

Minus

  • It will be necessary to spend a little on the means of mechanization, since self-made drill, even with a shallow depth of penetration, is clearly indispensable.

Drilling rig

Drilling rig

For a shallow well, a small-sized one( abbreviation - MBU) is enough. It does not make sense to buy it, since after the end of the work the equipment will not be in demand in the farm, because it performs only very specific operations. Who is interested in the price, you can specify the minimum cost of the simplest models - about 100 000 rubles( 15 "horses", the depth of drilling is not more than 90 - 100 m, and then, under certain conditions and not every tool).

Conclusion - it is more expedient to lease the MBU.Data on the cost of such a service is different, but the use of the installation during the day will cost approximately 8,000 - 10,000 rubles. If we take into account that the whole process will take no more than 2.5 - 3 days, it is in any case much more profitable. The figure shows one of these compact models.

It should be noted that not all MBUs in their composition have a pressure device. Perhaps the motor pump will either have to be purchased or rented separately. Gasoline models that are suitable not just for pumping dirty water, but for supplying liquid at the required pressure, cost from 28 000 rubles, diesel - even more expensive. The approximate price of "hire" is from 650 to 1,000 rubles / day.

Water reserve

In order not to waste time searching for it( in addition), it is necessary to count about 15 m³.This is quite enough, since a deep( artesian) well will not be able to drill with its own hands, so no one will be able to deal with it. Focusing on such a volume, it is necessary to select tanks - in capacity and quantity.

g-2 If the well is planned to be small, then this way. Near the place of the proposed drilling, "pit" is made. They have the form of baths, are excavated directly in the ground and are connected by a trough( trays).They are loaded with water, which is necessary for pumping into the pit. The dimensions of the "pits" are chosen arbitrarily, based on the required amount of washing solution.

What to consider when drilling

z-z Soil characteristics

It depends not only on the choice of tools( drills), but also on the advisability of using this technology. Since it is associated with the washing out of the rock under pressure, then it is pointless to engage in stony soils, and it is better to resort to another method.

Configuration and depth of the

water reservoir Otherwise, it will not be possible to calculate the required number of casing bends.

Operation procedure

General algorithm of actions. A specific list of activities is determined individually, taking into account local specifics.

Preparation of the drilling site

It consists in cleaning and leveling the soil for further installation of the MBU and placing the tanks for the drilling fluid.

Assembling and leveling the

installation The latter is quite significant. If the tool goes into the ground at least at a small angle, then under these conditions, drilling will not last long, and mounting casing knees will become much more complicated.

Location of technological capacities

If it is possible to replenish water supplies( for example, from a water supply system), this is taken into account when choosing a location. The length of the connecting sleeve "reservoir - trunk" is also taken into account.

Feature - you need to take into account that the fluid coming from the trunk has to go somewhere. When the well is pumped( but this will happen later, after the drilling and installation of the casing is finished), it is simply removed. In this case, water enters the same place - in the tank( "pit"), that is, circulates in a circle. Therefore, the first reservoir after the MBU fulfills the filter function, that is, it purifies process fluid from large fractions. During drilling, it is periodically cleaned.

Pump

The point of its location is determined by ease of use and all the same linear parameters of the hoses. One - in the tank, the other - to the MBU.

Note! All the nuances of connections, process line assemblies are indicated in the instructions for a particular drilling rig.

Everything else is quite simple. The drill "gnaws" into the ground, and the motor pump supplies the prepared liquid, which strengthens the walls of the pit and simultaneously cools the working tool.

If this technology is compared with the dry drilling technique, in which it is necessary to periodically remove a tool( along with the soil) from the pit, clean it, load it back, the advantages are obvious.

If the trunk is to pump only water, then, firstly, it will be absorbed into the ground. When working on sandstones - very intense, so may not even have enough of its large reserves. Secondly, the liquid will partially destroy the walls of the pit.

It is more expedient to pump a clay solution, which is easy to prepare with an electric drill and a butterfly nozzle( about 185 - 205 rubles, sold in any specialized store).In consistency, it should resemble kefir. This preparation gives a double effect - the walls are strengthened and the fluid consumption is reduced.

The soil is not uniform throughout the depth, and during the penetration process the tool meets its various layers. Based on their composition, it is necessary to adjust the "recipe" of the technological solution.

It should not be forgotten that achieving an aquifer is not yet the "crown" of all work. After the completion of drilling, it is necessary to produce the so-called "swelling" of the well, the technology of which is described in detail in this article.
