Dredging a well into the water: how to do it yourself

Water on the plot is needed. Many resort to drilling wells. However, the water in it is not always of high quality, and the process of building such a source is rather laborious.

Over time, water quality may deteriorate, so you may need to clean the source or deepen it.

Preparation for well deepening

Work to deepen the well should only be done when the water level has dropped significantly, or the well has just dried..

The main reasons for the lack of water are:

• a large number of artesian wells “fed” from one aquifer and leading off water;
• prolonged drought;
• digging a well at high water levels.

Tip! It is necessary to make sure that the withdrawal of water is not related to temporary reasons. The deepening of the well is carried out only after a long absence of water.

You can carry out the work yourself, but if you are not completely sure of the success of this event, it is better to trust the specialists. They will help to make calculations, without which all works will be just a waste of time and money.

When carrying out work, it is necessary to follow these rules:

• First of all, you need to answer the question whether it is possible to deepen the old well. The operation is advisable only if the cost of the work is not higher than the price of drilling a new well.
• The recess is performed at a depth that should not exceed three meters.
• It is necessary to make a preliminary pumping of water, for which it is better to use a submersible pump.
• Work carried out in wells consisting of no more than fifteen rings, which are not shifted relative to each other.
• If the imbalance is minor, you can align the well.
• Before work, concrete rings fasten special plates to prevent rupture.

Deepening methods

Recess with filter

We will understand how to deepen the well with your own hands using this method.

1. In a metal pipe with a diameter of 10 cm, fifty holes of 2 cm each are made.

1. Inside the pipe is fixed stainless steel mesh. After that, it install the pump. However, its diameter must be less than the internal diameter of the pipe.
2. A pipe is installed in the well drilled at the bottom of the well so that dirty water does not enter the upper opening.
3. The result is a homemade filter for the well. With the help of zhelonka it removes all the sand, which will allow to deepen the well by the required amount.

Well deepening with repair rings

After the water is removed from the well, digging is carried out. Perform this work, as a rule, do it yourself with a shovel.

Instructions for deepening the well provides for the following steps:

1. First of all, you need to make sure that the repair rings have no projections that can prevent the column from lowering.

1. In order to preserve the integrity of the column in the event of a displacement of the support layer, the rings are connected. To do this, use steel plates that attach anchor bolts to the walls, as shown in the photo. Each seam requires the use of four plates.

1. A bottom filter is used for digging. The digging continues until the ground begins to fall.

1. After that, carry out the descent repair rings. As they are lowered, the column is increased from above.
2. At the next stage, fix the repair column with the old ring with corner brackets.

1. Finally, the bottom filter is added and the joints are sealed with mortar.

Problems with lowering rings

If the rings do not fall, then you can try one of these ways.

• Along the circumference of the upper ring, holes with a diameter of up to 20 cm are made to the maximum possible depth. They are made manually using a 1-meter-long brown hole.

• If possible, the rings can be besieged using a crane.

Dredging in flowing soils

The quicksand is a mixture of sand, silt and organic impurities saturated with water. Due to the fact that he is under high pressure, it is worth to touch him, as he immediately comes into motion. There are many cases where an employee lost his life from the effects of flooded. So be careful and vigilant!

To cope with this phenomenon with a bucket of water is impossible. Therefore, the lack of special equipment is unlikely to help achieve results. Overcome this area by accelerated sinking into three rings with the installation of additional rings.

For sinking, special equipment is used, through which a large volume of sand can be lifted at a time. This will speed up the process of settling the column.

In the case of a column in the area with a solid rock quicksand, increases the efficiency of the method. Although the probability of meeting with a solid quicksand is small.

The deepening of wells in this case is carried out according to previously described technologies. Be sure to perform the mounting repair ring with a column. After completion of digging, boards of hardwood are laid on the bottom and the filter is poured. According to the same scheme, a well is deepened with a clay bottom.

Water purification

After completion of the main stages, they start cleaning the water source - the well. First you need to check the suitability of water, giving it to the analysis of specialists. If it turns out to be dangerous to use, then pour about half a kilogram of bleach into the well. An hour later, it is recommended to pump water.

Next, the inner walls of the well should be treated with antiseptics. For this, a solution of sodium hypochlorite can be used, for spraying of which a special high-pressure washer is used. Such equipment will allow not only to apply the compounds, but also to clean the surface from dirt and organic deposits.

The next step is to seal the joints and cracks, for which use liquid glass or cement mortar. At the bottom of the well lay the soil in a layer of 15 cm, which will consolidate the soil and reduce pollution.

Conclusion

Drying a well may necessitate its deepening. With a shallow depth of the well, these works are done independently. However, it is better to seek help from specialists. The source of additional information for you will be the video in this article.
