Casing drilling is the main way of the well equipment

Select pipe for drilling

Let's first understand, why the casing.Everyone understands that the soil tends to crumble.Therefore, if we make the drilling without casing, installed filters and the well eventually cover everything with soil, and hence the further repairs will be impossible.

as casing, you can use these products:

• pipeline made of plastic;
• Asbestos cement products;
• pipeline metal.

Each of these options greatly affect the quality of water and the duration of operation of the source.

consider each of them.For example, it is often used for large steel pipe wells.It is durable, reliable and capable of when properly installed will last for several decades.On this ground the pipeline advances almost no effect.However, steel is subject to corrosion, rust and therefore can get into the water and degrade its quality.It is necessary to install filters or as a casing to use stainless steel, which is worth a lot.

Casing pipe for drilling of asbestos may also be used, but they have their drawbacks:

1. They are not strong enough to accommodate at great depth, where the ground pressure is high.
2. Due to the small wall thickness, it is necessary to make the hole wider, which increases the cost of this type of work.
3. Asbestos may eventually have a negative impact on the quality of drinking water.

As you can see, significant shortcomings, but if the source is located at a shallow depth, up to 15 meters, then the product is fully applicable.

And of course the PVC pipe.His set almost anywhere, thanks to the following properties:

• No corrosion process and plaque;
• has good strength and durability, and thus a long service life;
• Easy to install;
• easily transported;
• High sealing joints;
• No negative influence on the water;
• low cost.

Despite some advantages, the plastic casing used for drilling at a depth of up to 50m.The diameter is selected based on the data of water flow and the borehole depth.

Doing well with their hands.The technology of well casing

With the help of special equipment, the main element of which is a drill, drilling process is carried out.borax size should be equal to or slightly more than the size of the casing.for casing pipes are inserted one by one, as you progress through the drill through layers of soil.Compound pipeline performed on the ground.

This process also involved a special powerful pump, which carries out the washing of the soil.The water is fed through special channels in the storm to soften the ground, stones and wash fractions.

When the desired depth is reached, the top casing member is fixed, and it is administered in the feed conduit for lifting the drinking water with a pump.

In principle, if the source is located at a depth of 15 meters, and you'll be able to do well.For this please be the following tools:

• drill a bailer, which is required to fasten the pipe threaded manner;
• tripod, to facilitate the drilling process;
• gate for turning the pipe in the ground;
• hammer, wrenches and sledge hammer to connect the coupler to the pipes.

Moreover, the casing for drilling must be greater than the design of the drill, bailer to easily navigate through the channel.

During drilling, and rotates the drill pipe and which periodically need to pull out for the removal of sand and clay.When reached the depth of two meters in channel insert the casing to the ground is not filled up well done.

Upon reaching the required level and the appearance of water in the desired quantity, is fixed on the casing surface.Then, in the input channel is connected PVC piping and pump.

As you can see, the process is fairly simple, but tedious.Two days is quite possible to drill wells up to 10 meters in depth.

After the well casing is made, experts advise to fill the bottom of the little sand and granite or marble chips, which will become an auxiliary filter, which means your water is of good quality.
