Description

The invention relates to a system for retention of rainwater runoff, revitalization of drained land and restoration of biodiversity, intended for reviving the ecosystem and biodiversity, especially for the area of construction of water retaining structures and recultivation of forest and agricultural land.

Current state of the art

The uncontrolled growth of compacted areas and artificially created slopes, where there is compression (compaction) and disruption of soil pores, for example on unimproved forest and approach forest roads, causes an increase in local floods, while the water flowing down them inundates villages, villages and towns, washes away from forests fertile soil, dries it out and also causes landslides. To date, various systems of water retention in nature are known, although they balance the water regime and subsequently this water is used in agriculture, industry or energy production, but the disadvantage of these systems is that they do not solve the problem of water retention in agricultural land and forests. they do not effectively prevent soil erosion, nor do they prevent floods and droughts.

Another known technical solution is described in Slovak registered utility model no. 5,252 entitled Integrated technological system for climate recovery, where the water reservoir block is connected to at least one treatment water biotechnical block and/or to at least one treatment water technical block, which is connected on one side to at least one technical water seepage block, which it is connected to at least one technical water absorption block and on the other hand it is connected to at least one technical water outflow block and on the third side it is connected to at least one technical water evaporation block which is connected to the water reservoir block. The disadvantage of this technical solution is the technical complexity, high costs of its implementation, non-revitalization of compacted soil and non-restoration of biodiversity.

The disadvantage of this technical solution is its technical and structural complexity, failure to revitalize compacted soil and failure to restore biodiversity.

The disadvantage of this technical solution is its high price, technical and structural complexity of implementation, failure to revitalize compacted soil and failure to restore biodiversity.

The disadvantage of this technical solution is that it does not use underground capillaries and does not restore biodiversity.

Another known solution is described in Czech patent file no. 297 401 entitled Anti-flood fence, where anti-flood panels are installed in the vertical direction between vertical stabilization posts and vertical stabilization posts and a landing threshold are installed in the reinforced concrete base plate, while a flexible horizontal sealing bar with profile grooves is placed on the lower edge of each anti-flood panel self-clamping hold the horizontal sealing bar on the anti-flood panel, while between the stabilization column and the joint of the adjacent anti-flood panels, a pressure bar with a flexible vertical sealing bar is attached to the stabilization column, and the anti-flood panels are attached to the stabilization columns using stirrups, which pass their arms through the mounting holes of the adjacent anti-flood panels panels.

In the upper unreinforced surface 1, there is also an artificially created inclined sloping surface 3 with a soil trench 31, which is the sloping soil with a depth of 100 cm dug up by an excavator, intended to interrupt the soil pores 62. In the lower part of the soil trench 31, there is an artificially created trench pit 9 with excavated slope soil from the soil trench 31 and from the trench pit 9. The trench pit 9 is designed to collect rainwater 6 from the soil pores 62. The trench pit 9 ensures the seepage of rainwater 6 through the water seepage 61 and the soil pores 62 into the groundwater 7. a compacted area 2 is created by the excavation pit 9. In the compacted area 2, there is one catchment precipitation pit 5 with soil compacted with a backhoe bucket. The catchment pit 5 ensures the seepage of rainwater 6 through water seepage 61 and soil pores 62 into the groundwater 7. In the catchment pit 5, according to fig. no. 3, one acceleration pit block 51 is created, which is designed to accelerate the outflow of rainwater 6 into the groundwater 7. Around the catch precipitation pit 5, according to fig. no. 2, a compacted surface 2 with a minimum width of 50 cm is created. On the compacted surface 2, behind one side of the catchment pit 5, there is an artificially created hilly area 8, which is a hill of dug up soil from the catchment pit 5. Behind the front side of the catchment pit 5 is a pit side 21 with a width of 50 cm. The pit side 21 is designed to ensure the lateral overflow of rainwater 6 and the sliding of the soil trench 31. Behind the pit side 21, a lower unreinforced surface 1 is created, which is an inclined sloping non-drained surface.

In the upper unreinforced surface 1, two decelerating slope blocks 11 are created. In the lower unreinforced surface 1, one decelerating slope block 11 is created. The decelerating slope blocks 11 are designed to disrupt soil pores 62 and slow down the runoff of fallen rainwater 6. Under both unreinforced surfaces 1 new soil pores 62 are created by gradually backfilling the decelerating slope blocks 11 due to the outflow of rainwater 6. In both unreinforced surfaces 1, an inclined slope surface 3 with a soil trench 31 is artificially created, which is the slope soil excavated by an excavator with a depth of 100 cm. to interrupt the soil pores 62.

Industrial applicability

The system for retaining rainwater runoff, revitalizing drained soil and restoring biodiversity can be used to prevent soil erosion, increase the retention capacity of the soil cover during rainfall, significantly slow down the runoff of rainwater from the soil cover, replenish groundwater supplies, and thus restore the hydrological regime of forests. meadows and agricultural land, creating new small water sources, protecting the territory from drought, fires and floods, restoring biodiversity, stabilizing the climate and mitigating weather fluctuations. In addition to saturating the soil and increasing groundwater reserves, it is assumed that there will also be a more uniform occurrence of precipitation. The use of the invention shifts the emphasis in the field of flood protection from ensuring the protection of the land during a flood to flood prevention, and further in the field of drought protection from security measures during a drought to preventive measures against drought, i.e. to the general maintenance of agricultural and forest land in good condition for satisfactory management of increased precipitation totals and ensuring sufficient water resources in the country. The use of the invention will ensure the ability of the territory to start fulfilling its natural functions anew in the distribution of rainwater to the roots of plants, to the sources of streams and to underground water. In order for rainwater not to flow down ditches, roads and compacted soils, but to soak into the soil pores, part 5 of the 3 m long soil ditch is artificially inclined at an angle of 5 to 10 degrees upwards to the impermeable wall.
