Well pipe: purpose, types and installation

We arrange wells at dachas even when there is a centralized water supply, because natural and free water is needed for irrigation, for baths and other household needs. A durable pipe into a well can be made of any quality materials, and its purpose is to multiply the lifespan of its maintenance-free operation.

Casing hollow construction will preserve the verticality and integrity of the walls, prevent their shedding and water pollution.

Characteristics of pipes

The quality of pipes depends on the time of use of the well, pressure, water quality. Now manufacturers offer us their widest range: from the usual metal to the innovative polymer. The diameter of these columns depends on the type of well..

Products must withstand such effects:

• loads of its own weight;
• ground pressure;
• shifts rocks.

Note! Due to poor-quality materials, the tubular wells simply fold, covering the expensive pumps, the water supply stops and everything must be re-digged.

Varieties of materials

Steel constructions

• With a 5-mm wall thickness, the service life is more than 40 years.
• Even on too mobile soils, the construction does not need repair.
• Make connections on the thread for sealing.
• Rust inevitably gets into the water, so we will also install a special filter for cleaning the well water.
• The cost of steel structures is quite high, and the installation is complicated by their large weight.

Concrete Well Pipes

• They are the best in sanitary terms.
• Portland cement 400 and pure quartz sand are used for their manufacture. The size of rubble should be less than 1/4 of the wall thickness. Cement, sand, crushed stone, water is taken in proportions of 1: 2: 3: 0.5.
• For high-quality reinforcement need reinforced corrugated steel (periodic profile and no rust). The ends of the smooth reinforcement are bent or with welded hooks, so that at tensile loads, steel and concrete work the same way.

Note! Making a well from concrete rings is faster and easier. Their internal diameter and height is 1 m, wall thickness is 12 cm. If we manufacture the rings ourselves, we will make the lower cone with a beveled lower edge, and install the factory one on the shoe, preferably with a chisel.

Products from polymers for wells, wells

Installation of sewer wells and pipes made of polymers is easier and faster, therefore, in Russia they have been actively used in recent decades.

Numerous advantages are obvious:

• they are not affected by corrosion;
• do not collapse from aggressive reagents;
• their solidity maintains the movement of rocks;
• they are practically eternal;
• their walls are easy to clean, both mechanically and with modern detergents.

Note! Low-cost and high-pressure low-cost polyethylene products are designed for wells up to 3 m, deeper the pipe can collapse from the load.

PVC-U pipes give us clear advantages:

• with a diameter of 125 mm, we have a sevenfold safety margin even at a depth of 30 m with a load of 5 tons;
• their rigidity is comparable with metal samples, but hydraulic properties are better;
• their small weight facilitates installation.

Characteristics of products Perfokor:

• made of high modulus polyethylene and mineral additives;
• most demanded models of diameters 110, 160 or 200 mm;
• these two-layer culvert pipes with a corrugated surface, perforations, are applicable in deep drainage devices;
• their main advantage is ease of installation.

Pipes for driving structures

The cost of this backup water supply is low, the process is as simple as possible if there is a sufficient aquifer.

Device

Drilling practice offers best practices and tools - homemade drilling tools.

• The main part - the tip diameter of 1.25; 1.5 or 2 inches from a holed pipe with a spear thickening at the end, and inside with a ball valve.
• We will install a tripod, fasten the tip to the pipe, put a woman on it, and knock everything into the ground with it.
• Next, screw the pump.
• We use pipes up to 15 m, preferably 3/4 ”galvanized or inch pipes.
• Intake filter is better to make a stainless steel pipe. Its length is determined by the aquifer: with a deep-seated vein - 0.5 meters, and the maximum - up to 1.5 meters.

• In the pipe we drill a lot of holes with a diameter of 1 cm, we wrap it with stainless mesh P52, which we solder along the edge with tin.
• Extension two-meter pipe connect steel couplings (threaded - coupling), sealing flax paint.
• Subsequently, if necessary, we will get this construction at least with the help of a jack and insert it back.

Features of a tubular well

The advantages of the Abyssinian well are indisputable:

• simple device;
• possibility of dismantling.

Tip! The filtering perforated tube raises water from a depth of up to 7 m, because the well pump uses atmospheric pressure. Therefore, the instruction recommends a simple upgrade: the installation of the screen filter and the NG-1 submersible pump. This will increase the capacity up to 15 l / min when lifting 30 m.

Conclusion

The main features of well pipes:

• the choice of material depends on the characteristics of the soil;
• metal products we put on unstable ground where there are motions;
• plastic models today are most in demand because of their unlimited choice in size, characteristics, types of polymer, and the price is also attractive;
• diameter of pipes is selected according to the possibilities of the underground source.
