Devices for cleaning wells: types and methods of their use
The fact that there is a well on your site is not yet a guarantee of uninterrupted supply of high-quality water.
Like any structure, it requires care and cleaning, otherwise water can only be used to meet technical needs. Therefore, it is better to prepare in advance the equipment for cleaning wells, know how to use them and be fully armed.
When you can no longer pull
When you start to notice that the water from the well began to smell strangely, muddied, or a rainbow film appeared on its surface, you have a desire to take action. This is the right decision, but to realize it immediately does not always work.
Professional cleaning of the well - an expensive event that requires some financial preparation. But, the longer we push a problem away from ourselves, the more actively it begins to remind of itself.
If these symptoms occur, the well must be cleaned immediately, because:
- filtration ceases to turn turbid water into transparent;
- the smell of their well shafts is comparable to the "odors" of a septic tank;
- the surface of the water is wiped with a resistant oily or iridescent film;
- static and dynamic fluid level drops noticeably.
It is impossible to drink such well water, and even this is problematic: its smell and appearance will become an obstacle even in case of strong thirst. So, you need to take measures, and you will most likely have to do it yourself.
What devices can be used
We have already told about how to clean the well by hand in an article about muddy water, so today we will talk about devices that can facilitate the work of the well cleaner, making it much more efficient.
Let's apply drainage and pressure head pumps
Manual cleaning is good, but it takes a lot of time and effort. If your work is not comparable with the result, it's time to think about automating a number of procedures. For example, it is possible to organize the forced circulation of well fluid, using for this purpose an injection unit and a drainage pump.
Each device in the process of cleaning the well will perform its own function:
- Drainage pump.It will pump water from the well to the surface. Thus, it will not only release the mine from the liquid, but also from the particles of dirt that are dissolved in it.
- Pressure pump. It should be mounted near the head of the well, so that it can pump water inside. In essence, his task is to play the role of a scraper.
Dense water flow, which is formed using pressure equipment, will clean not only the walls of the well, but also its bottom. Let us dwell in more detail on the procedure of cleaning the well using these two types of pumps.
First you need to immerse the drain pump at the bottom of the well. But how to do this so that the unit does not fall into the mud? To do this, construct a special stand with a wide base.
The pressure hose of the drainage device must be lowered into a container whose capacity is approximately 300 liters. An old barrel or bath that has served its own will be perfect for this purpose.
The pressure pump through the suction hose must also be connected to a tank or to a bath into which water will be pumped. The simplest wire filter should be attached to the end of this hose to prevent the pump from clogging and the circulation of fine dirt.
The pressure hose of the unit is equipped with a hydraulic nozzle, which allows it to generate a sufficiently dense jet so that it can perform the function of a scraper.
Preparatory procedures are completed, and you can start cleaning the well. Turn on the drainage pump to pump out all the liquid from the well. And then we pump it back under pressure, knocking dirt and layers from the shaft rings.
The whole process must be repeated several times. Hydraulics can be manipulatedlocated near the wellbore or standing on the stairs inside the mine itself. In theory, all sludge, sand and other foreign inclusions should settle at the bottom of the drainage tank.
When the walls of the well will be free from dirt and layers, you can treat their surface with chemicals. For these purposes, use the usual spray, filled with a ten percent solution of bleach.
After treatment, the well shaft will need to be repeatedly washed until the water ceases to smell like bleach.
Another method of using pumps
If you realized it in time and the situation in your well has not yet become catastrophic, you can get by with one drainage pump. For cleaning the well, it is recommended to use the following models of pumps pumping out cold water: “Dwarf”, “Brook”, “Spring”, “Kid”.
The pump must be suspended with a winch or cable at a distance of about 30 cm from the surface of the water. Half meter hose from the device must be immersed in water. It is used to agitate sludge and dirt in the liquid at the bottom. The second hose should be brought out to the place of discharge of dirty water.
Five minutes you whip the water, then turn on the drainage. The device should work until the water in the well is clean. It is recommended to clean the pump filter from dirt.
On average, the cleaning process will take about two hours. If during this time the problem is not solved, other more effective measures will have to be taken.
Scoop - the most affordable option
This option is perfect for those summer residents who are experiencing a shortage of finance, but have a fair amount of free time. A homemade scoop is a simple, but rather effective device that helps to get rid of muddy deposits on the bottom of the well.
For its manufacture you will need a piece of pipe of 100 mm, whose length will be no more than 2/3 of the diameter of the well shaft.One end of the pipe should be plugged with a removable plug, and the other should be cut at an angle of 30–35 °.
Place the pipe upwards, after which we weld two ears along the edges to its surface. Ears are needed in order to bind to them two ropes as fasteners.
We throw the shovel into the mine with the edge down so that it is pierced into the mud at the bottom of the well. Now you need to pull the rope, which is fixed closer to the cut. We want the scoop to scoop up as much dirt from the bottom as possible.
At one time, you can pull out about 2-3 kilograms of silty layers. So, repeating this operation many times, you can clean the bottom well. Usually the whole process takes more than one day.
Grapple - more difficult tool
To clean the bottom of the well from accumulated on its surface layers, you can use a grab - a mechanism for a limited range of work.
Outwardly, it resembles the jaws, which can close, seizing bottom sediments, and open, freeing themselves from their weight on the soil surface. As a tool for cleaning the well suitable manual grab. Find it on sale is not easy, so it is better to do it yourself.
The grab is the bucket we are used to seeing attached to the lifting device of a crane installation or an excavator. The manual fixture looks just like that, only its weight and size will be smaller.
To make the grab by yourself, we stock up on the following tools and materials:
- Steel sheet. Sheet thickness should not be less than 2 mm, but it is better not to weight the product, because the weight of the bucket along with the load will have to be lifted to the surface.
- Steel tire.
- Steel roller and finger.
- Profile pipe.
- Rod latch.
- Cable or chain. The length of the cable must be calculated in advance.It should be equal to two depths of a well with a margin of at least 2 meters.
- Welding machine and cutter or grinder.
So, we take a steel sheet with a thickness of about 2 mm, from which we cut out four semicircular sides, fitted with eyelets in full compliance with the dimensions shown in the photo. We drill holes in the eyes.
Now you need to cut two noses, one side of which is performed in a straight line, and the other is cut with teeth. The pitch and height of the teeth should be 20-25 mm.
These plates take a semicircular shape corresponding to the radius of the sidewalls. Each side of the midday is welded on two sides: one on each side. Now we have two polukša.
Polukovshi must be connected to each other. For these purposes, a steel roller with a diameter of 70 mm and a length of 202 mm is used, having a hole through the entire length into which we insert a finger. All parameters of the roller and finger are clearly visible in the photos.
To make thrust, we need a steel tire with a thickness of 5-6 mm. Look at the photo. There are dimensions that we need to comply. According to them, we have to cut the tire. Do not forget to drill holes.
To make the traverse, we need a profile tube. For the manufacture of eyes can be useful metal waste left over from our previous work. On the traverse fastened rod-latch. An additional cable of 500 mm length, equipped with a release ring, will then be connected to it. Such a device is used so that the bucket can be locked in the open position.
To pull the grapple or raise it to the surface, you need a steel cable. It can be replaced with a chain or rope of high strength.The length of the cable is selected taking into account the depth of the well shaft. One end of the lifting cable must be secured in an eye that is on the traverse. The other end is led out through the bucket roller, as well as through the hole in the traverse.
The operation of the grab is simple. Before using it, remove water from the well using a pump or any other method available to you.
The grab itself must be hung on a cable or chain to a well collar. To capture the soil, you need to lower the bucket to the bottom of the well. Polukovshi mechanism must be in a divorced state. When they are separated, the latch is cocked, which is fixed with a ring.
The bucket hooked to the ring actually hangs on the rod, which prevents the spring mechanism from straightening. When a grapple hits the bottom, the ring ceases to act on the rod, so the spring pushes it out. It turns out that the “jaws” no longer hold anything, and they begin to converge under the influence of their own weight, “biting” the silt and dirt.One pass of such a device allows to extract about a bucket of dirt from the well.
For a larger well, you can build a device and more powerful, but in this case it will be necessary to strengthen the lifting mechanisms. A winch can be used to remove cargo. In order to transfer the sludge to a certain place immediately after its extraction from the mine, a special arrow is constructed.
Work safety in the well
Yes, the safety of work in the well is not directly related to the devices that are used. But it is always necessary to remember it, because your own life and the lives of people close to you, who rush to save you, may depend on timely measures taken by you.
Work inside the well shaft is dangerous, so listen to our recommendations and follow them strictly.
- Do not clean the well alone.Invite two assistants so that they can hedge you if you plan to be in the mine itself.
- Do not neglect special equipment.A helmet will protect your head: being below ground level, you can accidentally get a blow to the head with a loose object falling from the side of a well. By the way, in the case of such falls you do not need to cover your head with your hands: just press against the wall of the mine. It is to the safety belt that the cable should be attached, with the help of which your assistants will be able to pull you out of the well in the event of an emergency.
- Watch your well-being.The deeper the well, the harder it is to breathe the sweeper near the bottom. The lack of oxygen can be felt already at a depth of three meters. Shortness of breath can cause panic or even loss of consciousness. Therefore, those workers who are on the surface of the earth should periodically hail their partner deep into the depths to make sure that he is in order.
- Provide yourself with reliable support.The bottom of the well does not always form a reliable footrest. Therefore, it is better not to stand at the bottom, but to sit on the platform to distribute the weight of your body over a larger area.
- Do not risk in vain.This item is directly related to the danger that may lie in wait for you in the well shaft.Often it is precisely in such mines, as in the basements, that an accumulation of combustible or carbon dioxide can form.
Combustible and carbon monoxide gases are heavier than air, so they can “leak” into the mine and remain in it for a long time. Therefore, when you pumped water from the mine, put a bucket with a burning candle in it. A candle flashes to indicate the presence of flammable gas, and an extinguished one indicates the presence of carbon dioxide. In both cases, work in the mine is prohibited.
If these our recommendations led you to the conclusion that you cannot cope with the problem of cleaning the well yourself, then so be it. Even a large amount of money spent on the work of specialists is nothing compared to your health, which is priceless.
Video instructions for making a grab
How to make a grab from an old gas bottle and use it in cleaning the well:
For the manufacture of the grab, you can use the old gas cylinder. It is this design in all details and listing the advantages presented in this video.
Before you start cutting the cylinder, do not forget to make sure that all the gas has come out of it.You should not make cuts along the seams of the cylinder or near them, because it is in these places that the metal of the product is significantly strengthened. Performing a cut in this place, you will lose much more time and effort.
How to clean the well with a manual grab:
This video presents the process of cleaning the well with a simple manual grab. Since the shooting at the bottom of the well is problematic, the operation of soil capture is shown on the ground surface. The process of extracting the grapple from the well and its cleaning from bottom sediments is clearly presented.
You can clean the well in different ways. Appliances that help you work are pumps for pumping cold water, grabs, or even simple shovels. Some of these devices can be made independently by adopting the recommendations that we have collected for you in this article.
