Description

Field of the Invention

The invention relates to the system for retaining rainwater runoff, revitalizing the drainage area and restoring biodiversity intended to revitalize the ecosystem and biodiversity, especially in the field of construction of water retention objectives and the recultivation of agricultural land and forests.

State of the Art

Uncontrolled growth of compacted areas and artificially created slopes where earth pores are compressed (compacted) and blocked, for example on slippery and unpaved forest roads, results in an increased number of local floods with water flooding villages and towns away by washing fertile ground, drying it out and also causing landslides. Until now, there have been various natural water retention systems known to keep the water regime balanced and subsequently, water is used in agriculture, industry or for energy generation. A disadvantage of these systems, however, is that they do not deal with water retention in agricultural land and forests, failing to prevent droughts and floods that erode the soil effectively.

Another known invention is disclosed in the Slovak utility model registered with No. 5 252 as an Integrated Technology System for Climate Recovery where a water reservoir block is connected to at least one biotechnological water treatment block and / or to at least one water treatment technological block which is, on the one hand, connected to the at least one technological block of water infiltration connected to at least one technological block of water absorption and, on the other side, is connected to at least one technological block of water drainage and on the third side is connected to at least one technological block water vapor tank. A disadvantage of this invention is its technical difficulty, high construction costs and failure to revitalize compacted soil, and recover biodiversity. Another known invention is disclosed in the Slovak utility model registered with No. 5 847 as Modular Structure of a Flood Barrier where each horizontal module has at least one adjacent vertical or inclined module in which each vertical module is equipped with a connecting bar anchored in the horizontal module, where the impact area of the vertical module is the side of the module vertically oriented towards the horizontal module, or

each inclined module is equipped with a connecting bar anchored in the horizontal module where the impact area of the inclined module is the side of the inclined module oriented in the opposite direction to the horizontal module. A disadvantage of this invention is its technical difficulty and the complexity of designing the embodiment and the failure to revitalize the compacted soil and recover biodiversity.

Another known invention is disclosed in the Slovak utility model registered with No. 5 726 as a Flood Barrier where a portable pedestal has an inflatable seal embedded around the perimeter and the size of the pedestal corresponds to the size of the frame built in the opening of the objective where the pedestal is located and fixed with at least two retractable pins using inflatable sealing. A disadvantage of this invention is that it is not possible to revitalize the compacted land, it cannot be used on forest roads and it is not possible to recover biodiversity.

Another known invention is disclosed in the Slovak utility model registered with No. 5 855 as a Flood Barrier where compartments and balancing strips are mounted in an airtight and waterproof balloon that is pressurized with liquid or air at a higher pressure if it is atmospheric or hydrostatic and can be closed using a plug attached to the stabilizing and compensating balloon with a valve on the outside of the balloon, a stabilizing wire and elastic clamps to attach a very long Flood Barrier, and a safety base can be placed under the balloon and attached with Velcro fasteners and auxiliary mesh; the safety base prevents the balloon from suffering mechanical damage or sliding downhill in rough, slippery ground. A disadvantage of this invention is its high cost, technical difficulty and complexity of designing the embodiment and the failure to revitalize the compacted soil and recover biodiversity.

Another known invention is disclosed in the Slovak utility model registered with No. 5 928 as a Flood Barrier where rubber bases and structural elements are connected to each other using connecting elements consisting of three panels connected by module-shaped folded hinges with a relevant rubber-based triangular cross section to which the panel with a plate of metal and recessed accessories is placed on the rubber base. A disadvantage of this invention is that it is not possible to revitalize the compacted land, it cannot be used with forest roads and the biodiversity cannot be recovered.

Another known invention is disclosed in the published Slovak application of utility model no. 230 - 2011 as the System for Retaining Rainwater Drainage and Revitalizing the Compacted Slope Area and its Implementation Process consisting of at least one compacted slope area in the unpaved slope area based on this invention which can be summarized as follows: at least one compacted slope area, there is at least one rainwater catchment ditch containing rainwater and consisting, on one side, of the sloping area adjacent to the slope and, on the other side, the area adjacent to the slope with the catchment area located above the level of the compacted slope area and the bottom of the infiltration drain placed between them with at least one infiltration of rainwater trapped in the groundwater. A disadvantage of this invention is that it fails to use underground capillaries and recover biodiversity.

Another known invention is disclosed in Czech Patent File No. 297 401 as a Flood Enclosure where flood panels are mounted vertically between vertical stabilization posts, and vertical stabilization posts and a dam sill are embedded in the reinforced concrete pedestal; in which a flexible horizontal sealing strip with profiled grooves is placed on the bottom edge of each flood panel; these profiled grooves self-attach the horizontal sealing strip to the flood panel at which a pressure bar with a flexible sealing strip is attached to the stabilizing post between the stabilizing post and the connecting element of the flood panels, and these flood panels they are connected to the stabilizing pillars by means of stirrup-type parts whose arms pass through the assembly holes of the panels against the neighboring floods. A disadvantage of this invention is in the high construction costs, the failure to revitalize the compacted soil, the unavailability to be applied to forest roads and the failure to recover biodiversity.

Another known invention is disclosed in the Slovak utility model registered with No. 6 839 as the System for Retaining Rainwater Drainage and Revitalizing the Compacted Slope Area which may be summarized as consisting of at least one compacted slope area into an unpaved slope area based on this invention which may be summarized as follows: in an unpaved slope area, with earth pores, there is at least one deep pit trenched with rainwater made along the contour; In this pit, is placed excavated sloping earth in which the bottom of the sloping deep hole is connected with groundwater by infiltration of water and pores from the ground; and
