Method of creation of additional water stocks in recovery of peat bogs

FIELD: agriculture.

SUBSTANCE: invention relates to flooding of worked out peatlands in the restoration of peat bogs. The method is carried out in the autumn-winter period with the establishment of a stable average daily air temperature below the freezing point of water with use of ice blocks made in the form of polyhedra. Near the available source of fresh water the blocks of ice are produced. Then the blocks manufactured using the vehicle are moved to the mapped areas of worked out peatlands and put in few layers in the structure in the form of a polyhedron. At that at each mapped area of worked out peatlands, depending on the area of the site one or more structures from blocks of ice are erected.

EFFECT: increased level of fire safety in the areas of worked out peatlands, reduced level of the risk of emergencies and improved overall environmental situation around the worked out peatlands.

The invention relates to peat extraction, specifically to restore peat bogs, and in particular irrigation of depleted peatlands.

At present in Russia the area of the depleted peatlands estimated is about 900 thousand hectares (in the European part of Russia is 70% of all worked out peat bogs), and is used only 20-30% of these areas. Disturbed marshes, primarily bogs developed for the extraction of peat, are unproductive lands with unclear trend and speed of healing, periodically threat of fires, air pollution from fires and surface water for erosions, etc. So for ecological rehabilitation of depleted peatlands, resume them in the swamp - and tortoiseshell processes, Renaissance biosphere functions, as well as to eliminate erosion and fire situation carry out the restoration of depleted peatlands (rewetting), including their initial watering. For example, one of these projects (the Rationale for re-swamping peat deposits "Boolean moss", State scientific institution the Institute of Zoology of NAS of Belarus, Minsk, 2007) restoration of wetland fauna and flora will occur che is ez 10-15 years, the functions of the peat accumulation and binding of carbon dioxide will recover in a few decades. Only on irrigated area developed peatlands, according to experts, you need 2-3 years.

When restoring depleted peatlands one of the main objectives is the creation of an effective system of accumulation of water to restore the water balance of the peat bog cutover. As noted in one of the sources (Adeleke. Green pipeline on drained peatlands. M: Rosselchozizdat, 1984 page 7.), "when there is insufficient rainfall and strong evaporation on peat-bog soils intensively drained by a network of public or private drainage, ground water often goes deep into the earth, the soil moisture is below the optimum. In such cases, on peat soils it is necessary to apply additional (artificial) hydration... the most common problem events on irrigation of wetlands is the lack of water needed to restore the marshes". This lack of supply, as a rule, a supply of water from natural sources or artificial reservoirs, which, in turn, is associated with considerable expenditure of energy and material resources, the complexity of the work in hard to reach places, it is Timothy take into account the scarcity of freshwater resources in many regions, seasonal restrictions on the carrying out of such works.

Technical result achieved in the claimed invention, is creating additional sources volume of water necessary for irrigation developed peatlands in the reduction of the volume of intake for these purposes, fresh water from natural sources and man-made reservoirs during their intensive use in the summer, eliminating seasonal restrictions on the carrying out of works on irrigation developed peatlands in improving fire safety in areas depleted peatlands in reducing the risk of occurrence of emergency situations in improving the overall environmental situation around the developed peatlands in reducing the total cost of material resources for liquidation of consequences of emergency situations, environmental and technological disaster.

The technical result is achieved by the fact that the creation of additional water supplies is carried out in the autumn-winter period of the year with the establishment of a sustainable average daily air temperature is below the freezing temperature of water and use ice in blocks, made in the form of polyhedra.

The invention is illustrated by drawings.

Figure 1 presents: 1 - the natural source of fresh water (or artificial reservoir with fresh water is), 2 - site manufacturing of blocks of ice, 3 - block of ice, 4 - vehicle for delivering blocks of ice on the mapped areas 6 peatland 5, building 7, made of blocks of ice.

Figure 2 presents the structure of the stacked multiple layers of 3 blocks of ice.

In this case, as shown in figure 1, near the available natural source of fresh water (or artificial pond with fresh water) 1 at site 2 are made of blocks of ice 3. Custom blocks using the vehicle 4 then move on mapped areas 6 of the peat bog cutover 5. Delivered to areas of peat blocks are then several layers, as shown in figure 2, the structure 7 in the form of a polyhedron. Each mapped area of the peat bog cutover depending on the area in a similar way to erect one or more structures from ice blocks.

With the beginning of spring-summer period of the year with increasing ambient temperature, and begins the process of ice melting in the construction of the surrounding snow cover of peat and frozen in winter soil layer, however, due to the significant volume of water stored in the erected structures in the form of ice, and geometrical parameters of the structures of the melting of ice in such a construction will be less of intensive the m and longer, than the process of thawing of the snow cover and frozen in winter the upper soil layer of peat. As a consequence, the soil is saturated Obvodnogo peatland water will occur over a longer period of time and more efficiently than in normal conditions.

The way to create additional water supplies while restoring peat bogs, characterized in that is carried out in the autumn-winter period of the year with the establishment of a sustainable average daily air temperature is below the freezing temperature of water using ice in blocks, made in the form of polyhedra, with near available source of freshwater to produce blocks of ice, then made the blocks with the help of a vehicle moving on mapped areas of the peat bog cutover and stack several layers in the structure in the shape of a polyhedron, with each mapped area of the peat bog cutover depending on the area to erect one or more structures from blocks of ice.
