Drilling water wells with small-sized installations is the only way to solve the problem of arranging a source in refined household plots. This is due to the compactness of the equipment, which will be located in the yard without harm to lawns and plantings.
The principle of operation and the device used equipment
The problem of pollution or lack of water during the warm season is common, so the owners of country houses are faced with long queues at organizations specializing in drilling wells. In this case, you have to make a choice: postpone the solution of the problem for 2-3 months, or start fixing it yourself.
Drilling with small-sized equipment is carried out at any time of the year, the execution technique is simple, the equipment has an acceptable cost. Experts advise buying a drilling rig, and not renting it, since it may come in handy more than once in the future. Working with an assistant, as a rule, one day is enough for re-drilling. The operating instructions are enclosed with the unit upon purchase.
Compact industrial equipment is designed for drilling wells using auger technology. Reverse or direct flushing is applied simultaneously with the immersion of the drill into the soil strata. There should be free space around the mobile drilling station as the soil will be pushed to the surface as the rods deepen.
The kit includes:
- Welded frame made of high strength metal. A profile made of a material with high corrosion resistance is used, the surface is covered with an active chemical composition. The width of the uprights in the frame does not exceed 3.5 meters. Taking into account different modifications of drilling rigs, their height ranges from 2.2 to 3.5 meters.
- Lifting rope and winch. The latter, as a rule, can withstand a load of up to 1 ton.
- Electrical equipment: remote control, engine and control unit. The motor is powered by 220 W. If there is no electricity on the site, internal combustion is used.
- Drilling equipment: rods, barrel and drill. The tips are made from special alloys that can handle all types of soils effortlessly.
When purchasing equipment, they check the assembly quality of the installation, as well as the availability of the necessary documentation. The set includes a step-by-step algorithm for performing the work.
Work technique
Before starting work, you need to dig two depressions near the area where the drilling rig will be installed. One pit will be the filter, and the other will be the source of fluid supply to the barrel. The pump must be installed near the main tank. For convenience, it is better to cover the bottom of the recess with a thick film. The depth should be 60-70 cm, the perimeter is 50 * 50 cm. It is required to connect these pits with a small trench, along which the liquid from the filter will be transported to the main pit.
Assembly of the mobile drilling rig can be done by one person, usually the time spent does not exceed 1 hour. The hose must be connected to the pump.
After starting the drilling rig, you need to carefully monitor the angle of inclination at which it enters the ground. The tip should be immersed strictly vertically into the surface layer. You can follow the corner using a regular building level. After the first layer of soil has been overcome, the first rod is removed by reverse, the drilling rig is raised and a new second rod is installed. The work is carried out using an electric motor. Gradually, as the layers of earth pass, the bar is lengthened to the desired depth.
During operation, it is necessary to regularly remove contaminants from the filter pit, monitor the composition of the liquid: when changing the rock, it is necessary to replace the soil solution.
Signs of penetration into the aquifer
Drilling with small rigs allows continuous monitoring of the immersion depth. The main signs indicating a deepening into the aquifer:
- Reducing the level of the solution in the sump.
- A sharp increase in the rate of submersion of the unit in the earth.
- Increased vibration - it seems that the drill simply falls into the ground.
- Sand impurities appear in the filter pit.
After reaching the required depth, it is important to flush the barrel with a pump. The final stages are to dismantle and disassemble the rods. After removing the drilling rig, you need to start installing the casing. The end must be equipped with a filter so that the pumped-out water contains a lower concentration of silt, small algae, sand and other solid impurities.
Advantages and disadvantages of the method
Equipment owners note the following advantages:
- Mobility and low weight of the installation. The total mass of all components of the kit does not exceed 0.5 tons, while the frame is completely collapsible. For transportation of a small-sized drilling rig for wells, there is no need to rent a truck, you can use a light trailer.
- The maximum drilling depth reaches 100 meters. The water intake intended for domestic needs with the required flow rate to provide households with water is equipped at a depth of no more than 50 meters.
- High power and performance ensure high working speed. On a site with any conditions, you can equip a well within 10-12 hours.
- Easy to manage and install. It is preferable to carry out the work together. It takes about 1 hour to assemble the structure.
- Purity. During work, the top layer of the soil is not damaged.
- The installation is used on various reliefs, refined and built-up areas.
Of the shortcomings, experts single out only one - the inability to work in very hard soil, where there is a large amount of hard rocks and stones.
Prices for drilling artesian wells with small-sized equipment vary greatly depending on the region and the depth of the aquifer.
Drilling and equipping an artesian source is a laborious and financially costly process. After the completion of the work, a passport is drawn up for the well, where the technical parameters and characteristics will be indicated.
