Properties drilling techniques well water

The presence of water in the area - it is an essential condition for a comfortable stay. Whether it is a villa or a house. Lucky for those who have city water (as a rule, a suburb). Other solutions to the problem: imported water (poured into the container in a warm room) or the well.

The level of manhole water, for example up to 15 m also not found everywhere. Dig wells and build now is not low cost. Although there is an option to the depth of these layers Abyssinian drill hole. It is possible to drill even in the home. Features there too much, try to describe the details of one of the articles.

If the water is below 15m, then the optimal variant drilling using specialized machinery - rig.

Water well drilling for a hundred, or even more meters, where there are vast reserves of water in the reservoirs - it is not a small expenditure. Especially, in many regions for the use of such water from these depths is necessary to obtain a license. If such a hole to drill, from the arrangement of the water tower and conduct water supply for the whole village. And it is also not small money.

The area where is my site. there are aquifers are not so deep - 30-40m. My neighbor hole depth of 33m.

Prepared the necessary funds at the rate of 1800-2000 rubles. / M and reached an agreement with drillers, who drilled his neighbor, and his words are professionals in their field.

Advance was purchased with the lower vibration pump water intake (so said drillers) and cable 40 m long steel cable, hose 25 m (25 m I had) and clamps. Tube for joining hoses was.

On the appointed day he arrived in the morning drill. Works lasted all day, so you should start in the morning.

Buryats not just into the first place, where will indicate the site owner. Although, if you insist, it may be so, but do not guarantee that there will be water in this place.

It was said that some had to pay the cost of diesel fuel and drilling was leaving because the result was no - there was no water.

Many will laugh, but experienced drillers in this topic define the water frame, or vines (old). In another way it is called biolocation. The method shows a very high level of contact.

I corresponded with a geologist. He said that many customers defines not only a place to drill for water but also mineral deposits. For others - faults in the earth's crust. His method has fewer errors than an expensive method of seismic soundings subsoil.

It has long been optimally determined where to drill the well - 4-6 m from the foundation of the house and the lower portion (for comfortable arrangement of the caisson later). The day before the rig soon decided himself to check the presence of the frame aquifers. I read once how to work with the frame. Several times the frame pointed to one place. Here, I put a peg. Before drilling driller confirmed his frame, that yes, the location is good, the water must be guaranteed.

Starting the process. The brigade two people

Mounting the next segment of the screw.

It passed the necessary depth and remove the screws. The liquid clay on them says that the water is.

Further, it was necessary to lower the casing. Use steel pipe 133mm in diameter. Plastic - in any case. There are many cases where at the slightest shifting of the ground it broke.

In the afternoon, I did not take off process, engaged in masonry fence blocks, and drillers have asked them not to shoot in. It describes the process as follows: in the first three tubes (3 m each) are cut grinder gap for water ingress into the wellbore. Special clip is fixed on the first pipe and the well bore to her and on her second welded. The segment is lowered to ground level and the second pipe. Pipe is welded next and so on until the column rests on the bottom of the well.

Then followed the process cable-percussive drilling. This made it possible to "blow layers" hydraulic impact from falling column, to deepen the wellbore and raised to the surface of sand and clay slime (a column with the bottom valve).

Even between the pipe and the walls of wells more bombarded mushrooms 20 buckets small pebbles. I sow it in advance from the existing heap CBC. And so they should pebbles 100R. bucket. Gravel is necessary in order that the process would wash out the sand layers it filled the cavity and serving to prop the layers and filter the water. If you do not, then pump the well to clean water can be very long. Pebbles fall asleep, not all drillers.

A clay slurry, which was poured from the column. Column dropped on the rope to 20 times with measurements of water level. Following the results of the mirror of water was determined to be 25 m. That is, water column in the well 8 m.

Further mounted hose pump is secured to the cable, fixed on all ties, and lower the pump into the well almost to the bottom. We turn on the pump.

I went water with the clay and sand

Washed out here such sand

By the end of the day the water went lighter.

The cost of a well depth of 33m at a cost of 65 thousand. Although it was announced in 1800 RUR / m, the cost of covered meters -. Almost 2,000 rubles. Ostensibly due dense sandstone formations 25 m.

But not everything was so simple and trouble-free. Ahead difficult waiting period wellbore washing pump with a constant pulling out its washing and the change to the new. When there was a partial flushing reservoir well silting. Sand from which will have a long time to pump. This work is still ongoing. But this process with a lot of subtleties - in the next article.
