depth of soil freezing depends directly on the type, climatic conditions, humidity and others.Features and options are taken into account during drilling, construction and other kinds of economic activity.
What is the depth of seasonal soil freezing?What does this figure?
This is a random variable, and it can not be permanent.This is due to the fact that some of the factors affecting the performance, over time, almost no change (eg, soil type, topography), and others - on the contrary, are constantly changing (soil moisture, snow depth, intensity and duration of the reduced temperature, etc.).With the construction of buildings of great importance is the depth of soil freezing.In the Moscow region now under active construction.On how deep the soil freezes, the value depends on the construction of deep foundations.During the construction should take into account that in the winter (in the case of permanent residence) of land for the house warming.With this target depth to which the soil is frozen, it can be reduced to fifteen or twenty percent.To provide maximum heat retention of the soil is capable of high-quality insulation tape width of a half or two meters.It is laid around the house, thus creating a heat insulating blind area.
Why the different depth of frost penetration in the Moscow region?
values range from 50 cm to 1 m 80 cm. This difference is explained by the specialists of different density of the soil.The stronger and denser cold ground, the more the ground freezes.In soil, saturated with moisture, the indicators will be higher than in the dry.As such, the average value in the Moscow region is absent.But there is a normative depth of freezing ground.SNIP calculated value is set as follows - 1 meter 40 cm. But it must be said that in its definition into account the extremely harsh climatic conditions: high level of ground water, the bitter cold, the lack of snow.In fact, the depth of frost penetration in the Moscow region is different from the existing standards.Often it does not exceed one meter.If the winter is very cold, there is little snow, the level may be up to one and a half meters.In the west suburbs soil freezes about 65 cm, while in the east, north, in the southern part - up to 75 cm.
Influence of soil type
depth of frost penetration in the Moscow region depends on various factors.One is the type of soil.For example, sandy ground freezes to large, in comparison with the clay, the depth.This is because the clay is more porous than sand.For suburbs characterized by sandy soil, loam, coarse soil, peat and loam.The maximum level can accurately identify experts, taking into account all the factors in the calculations in the complex.For example, the coarse soil begin to freeze at 0 degrees.For sand and sandy loam freezing depth - 132 cm, and for the loamy and clay soils - 1.2 m.
