The question of how to insulate a well of concreterings, worries mainly summer residents, owners of private houses and villagers. Most often, this issue is solved even before the construction of the well, taking into account the climatic conditions. But this is not always the case. It happens that we didn’t think about warming initially. And when faced with a problem and the freezing of water in the well in winter, its owner is fully aware of his mistake. Thus, the answer to the question about the insulation of the well can be divided into two specific guidelines. The first will tell you how to insulate a well of concrete rings immediately during construction. The second is about what can be done after the fact.
Why did nobody warm the wells before?
The use of modern materials is in many waysfacilitates the construction process. This is speed, and durability, and economic feasibility. But proven for centuries, "grandfather's" methods have the right to exist. Previously, the wells in Russia were built mainly from special wood species. The excellent characteristics of such a well allowed it to be used for many years, and the low thermal conductivity of the wood did not allow the water to freeze even in the most severe frosts. But now such technologies are a thing of the past, and most often ready-made concrete circles are used for construction. By digging them up, they are gradually immersed in the ground, reaching the desired depth. In order for the water inside the well not to become ice, its level should not reach the level of soil freezing in winter. If this condition is met, then problems are extremely rare. But no one is protected from force majeure and natural disasters. In any case, reinsuring does not hurt well in advance, because it does not require a lot of additional effort, and the money spent on insulation, not so great as to risk.
What happens if you do not create a heat insulation layer?
Ignoring the warming can not only deliverinconvenience in the form of lack of drinking water for some time. If a pumping station is installed in the well, and water pipes to the house run from it, the freezing of water will lead to the failure of all equipment. Its repair is a very expensive procedure; in addition, the matter is complicated by the fact that the ground freezes through the winter, and if the water in the pipes also freezes, this may cause them to break. Recovery work will need to be done in difficult conditions or even postponed until spring. The expansion of the liquid during freezing is also the cause of the destruction of the concrete rings and the joints between them. In spring, during floods, the abundant runoff of groundwater, their pressure on the walls of the well is significantly increased. And any gaps will lead to the inevitable leakage of dirty water with various impurities into the well. To avoid such a problem, you need to immediately find out how to insulate a well of concrete rings and do all the work correctly.
How deep should the heater be laid?
When work is done during construction,insulation must be laid around the well gradually, as it is burrowed. The depth of the laying of insulation depends on the climate in the region. It happens that even very deep criminals freeze over, the depth of which exceeds 15-20 meters. Most often it will be enough to lay insulation to a depth of no more than one and a half to two meters. The technology of this process is simple, the main thing is to follow the instructions on how to insulate the well. Ways of warming of a well in many respects depend on what winter in the region.
Outdoor insulation
Если морозы не очень сильные, земля не промерзает deeply and for a long time, it is possible to protect the crynite from above by installing a wooden blockhouse above it with a tight-fitting lid. Such a house can not just put on the ground around the well. For it is necessary to equip the foundation. To avoid distortion and subsidence, the foundation should be arranged according to all the rules, to a sufficient depth (not less than the average level of freezing of the ground) with a width of one meter. Before the concrete solution is poured, a cushion of layers of sand, gravel and soil is created at the bottom, which will play the role of a drainage system. The pillow must be carefully tamped and then pour the solution. After installing a wooden frame in the gaps formed between it and the walls of the well should be laid insulation. For this purpose, you can use mineral wool, foam sheets, expanded clay or penoizol. The inhabitants of the southern regions respond well to this method, while those who live to the north are dissatisfied with the results.
Well insulation technology
How to insulate a well from concrete rings under the ground is a slightly more complicated question. Such work is carried out in several stages.
- Кольца колодца предварительно нужно обработать special means to prevent the ingress of groundwater inside. But when choosing it is important to consider environmental friendliness and the possibility of using the tool in work with wells.
- The next layer goes directly to the layer of insulation. Than to warm a well from concrete rings, we will consider a little further.
- Insulation is necessary to wrap the hydro-and vapor barrier layer. Most often for these purposes use a film. Such a measure will help to avoid the contact of the insulation with the ground, the condensate settling on it.
- To fix the entire structure around the rings, a wooden formwork is installed; it holds all the layers together.
- In conclusion, the trench needs to be covered with earth.For this process, experts advise not to use the soil from the trench itself. It will be correct to alternate layers of two materials with different caliber. It can be sand and gravel or clay with expanded clay. Layers with a small fraction are usually laid up to 15 cm thick, and others - 20 cm. Such a measure will help to create a high-quality drainage system, this will reduce the risk of water pollution in the well and reduce the pressure on its walls.
This is a classic, time-tested method, and the most positive reviews about it.
What to do if krinitsa already built?
Как утеплить колодец из бетонных колец на зиму, if it is already built? The technology itself is the same as in the previous case, but you have to dig a trench. Such work needs to be done manually with a shovel. The use of specialized equipment can lead to the displacement of the soil and rings, the integrity of the soil layers. The rest of the work is done by a given technology. Separately, it is worth noting that it is very important to worry about a good lid for the well. Heat loss due to its absence or poor adherence to the edges will also cause water to freeze. When a wooden blockhouse or other structure is installed above the well, its lid is made in the form of a multi-layer panel, in the middle of which there is a layer of foam or mineral wool. Outside the well, the well is decorated with a concrete hatch and a plastic plug. Those who live in areas with warm winters characterize this method as fairly cheap and practical.
What options insulation usually used?
To learn how to properly insulate the well fromconcrete rings, you need to know what it can do. There are quite a few options. Among the newest ones is insulation with penoizol. The application of such material on the walls of the well eliminates seams, penoizol completely covers the entire space, eliminates leakage of cold air or water. This technology involves the use of special equipment, it will not work out manually. And the cost of the service is not cheap, so it is still not very common in our country. In warmer regions, mineral wool is sometimes used on folgoisol. The advantage of this option is the ability to wrap the insulation as tightly as possible around the well. But some experts caution that this material crumbles easily and can eventually break up into individual fibers and get into the water of the well.
Polystyrene insulation
To warm a well from concrete ringspolystyrene is the most successful option, experts say. The properties of this material are truly unique. It is an excellent barrier to cold air, and is also very durable and inexpensive. For these purposes, most often sheet material is used, which is not always convenient, because it is problematic to bypass sheets with rounded rings.
Manufacturers have found a way out of the situation andoffer consumers ready-made insulation parts that have a semicircular shape. The sizes let out standard, under the most widespread diameters of well rings. In addition, you can use bulk granulated polystyrene foam. In this case, in order to create a skeleton, it is necessary with the help of wooden slats to attach a layer of roofing material on the ground around the walls of the crinite and pour it into the resulting granule opening. In this way it is possible to insulate the well not only with foam balls, but also with other loose insulators.
This is an effective method, and the owners of the wells, who chose it, confirm the reliability of such insulation.
