Description

The utility model relates to the operation of partially-buried structures used, for example, as unheated storage facilities.

The utility model can be applied in climatic zones with stable snow cover in winter.

There is a well-known semi-buried shelter GO containing walls installed in a recess with ceiling ceilings covered outside by an earth embankment, the soil of the embankment is separated from the ceilings and walls by a layer of waterproofing (see Typical design P-4-100-328.84 “Prefabricated half-buried anti-radiation shelter for 100 shelters. Size 12 per 6 m "General view. Section.)

Thermal insulation of a known structure is provided mainly by a layer of bulk soil on the ceiling of the premises. In winter, the thickness of the snow cover, which significantly affects the overall thermal insulation of the structure, is not uniform. It is minimal in the area of the ceiling of the structure, because the snow is partially melting or blown away by the wind (especially if the semi-underground structure is in an open area). The maximum thickness of the snow cover is in the zone of the slopes, i.e., above the walls of the structure.

That is, the disadvantages of the known semi-underground structures include non-uniform thermal insulation in winter, caused by the uneven thickness of the snow cover on the semi-underground structure.

In the proposed utility model, uniformity of the overall thermal insulation of the semi-underground structure in winter is ensured by ensuring the guaranteed thickness of the snow cover over the floors of the structure, i.e., by ensuring a uniform thickness of the snow cover over the entire room of the semi-underground structure.

The specified technical result is achieved in that in a semi-underground structure containing walls in the recess with ceiling ceilings, covered outside with a soil embankment, where the soil of the embankment is separated from the ceilings and walls with a waterproofing layer, a volume geogrid is fixed on the surface of the soil embankment, the cell height of which is more than 0, 2 m and exceeds the size of each side of the cells of the geogrid, and the surface of all elements of the geogrid is white.

An analysis of the solutions known in the art did not reveal technical solutions with the claimed combination of essential features, which indicates the compliance of the claimed utility model with the condition of patentability “novelty”.

The conducted experimental work, observation of the formation and maintenance of a snow cover uniform in thickness on volumetric geogrids with a cell height of 0.2 m, confirm that the claimed technical solution meets the criterion of "industrial applicability".

The essence of the proposed utility model is illustrated by schematic drawings, where in FIG. 1 shows a semi-underground structure, a general view. In FIG. 2 is a view of a fragment of a geogrid without snow.

The semi-underground structure contains walls 2 installed in the recess 1 with ceiling ceilings 3 covered by an external soil embankment 4, the soil of the embankment 4 is separated from the ceilings 3 and walls 2 by a waterproofing layer 5, a volumetric geogrid 6 is fixed on the surface of the soil embankment 4, whose cell height 7 is more than 0.2 m and exceeds the size of each side of the cells 7 of the geogrid 6, the surface of all elements of the geogrid 6 is white. The geogrid 6 is fixed on the soil embankment 4 with the help of fixing anchors 8. All surfaces of the elements of the geogrid 6 are white in color, which increases its reflective ability and, as a result, slows down the melting of snow (not shown in Fig.) Inside the cells.

The described method for additional thermal insulation of semi-underground structures in winter is mainly applicable to old structures, where work to increase the thickness of the layer of soil embankment on floors is undesirable or inappropriate.

In the winter period, during snowfall, cells 7 of the geogrid 6 are filled with snow, which provides additional thermal insulation of the semi-underground structure. Snow that has filled the geogrid cells with wind is practically not blown out. To significantly increase the thickness of snow insulation, it is possible to install several layers of geogrid. The sizes of the geogrid cells are optimal when filling them with snow.

In comparison with the analogue, during the winter operation of the semi-underground structure, improved thermal insulation is provided. A geogrid with a cell height of 0.2 m provides an increase in air temperature inside an unheated room by 2-3 degrees and a decrease in the magnitude of changes in air temperature.
