CZ22386U1 - Augmentation of ground water reserve in connection with flood-protecting measure - Google Patents

Description

Technical field

The technical solution relates to better use of rainwater, or to mitigate the flood wave, especially for the abundance of groundwater reserves.

Background Art

The current use of land by humans (housing, agricultural land use, changes in afforestation and surface water treatment), in parallel with the advancing climate change, is a major intervention in all natural life conditions on Earth, with changes in nature's water circulation. At present, floods are a common occurrence, and with the surplus of this surface water in recent years, there has been a steady decline in lower water and therefore a frequent phenomenon is the drying of less deep wells or boreholes. There are currently no known solutions that at the same time limit floods and serve as a groundwater abatement system. Only the reduction of flood damage and eventually deepening of wells for obtaining sufficient supply of groundwater for human needs are always solved. These activities have not yet been coordinated.

The essence of the technical solution

This technical solution is based on the assumption that both issues, ie the abundance of groundwater and the reduction of flood damage, are dealt with simultaneously, using the following arrangement:

In the case of watercourses artificial troughs are created, which are closed before flooding in normal water level by means of baffles with overflows. These man-made troughs end up with boulders in front of which boreholes are created into the earth, in the case of porous and softer rocks, pits can be created. When the river level is elevated, the water overflows overflows and flows into artificial troughs, where it floats in front of the vaults and flows into boreholes, respectively. to the retention object - infiltration pits in the case of porous or softer rocks. To prevent clogging of boreholes, these are provided with removable baskets on the surface with a suitable filter to retain coarse dirt. The boreholes can be preferably equipped with a sheeting with infiltration holes. In the case of containment objects, the infiltration pits are spilled with sand and gravel for better infiltration. If there are other openings in the vicinity of the river, such as old unused mines, water from artificial troughs can be directed here, where they can be used for infiltration and hence the abundance of groundwater. Here again, it is necessary to provide a sheeting with infiltration holes together with a device to prevent coarse dirt from entering the mine.

BRIEF DESCRIPTION OF THE DRAWINGS

The technical solution will be explained in more detail by means of drawings, where Fig. 1 schematically shows a river with tributaries and artificial troughs, including the created ramparts with infiltration boreholes, respectively. FIG. 2 is a cross-sectional view showing the wall, the infiltration bore and the bottom water obtained from the borehole;

An example of a technical solution

On the river and with the possible tributaries 2 in the places of the Floods there are artificial troughs 3, which are separated from the river by a barrier with an overflow 5. The artificial trough 3 is directed to the spaces in front of the artificial or natural rocks 4 where the water is retained. In this space, there are forging holes 7 through which the water is led underground. The infiltration boreholes are provided with filters 8 to collect coarse dirt. In the case of a higher water level in the river 1, the water flows over the overflows 5 into the artificial troughs 3 and flows into the space in front of the cylinder 4 where it flows through the filters 8 into the infiltration wells.

7. This retains a certain amount of excess water, and at the same time, through artificial channels 3, it reaches the infiltration borehole 2 and then into the underground where it soaks up and supplies the stock

- 1 CZ 22386 Ul of groundwater. In the case of porous softer rocks, the set of infiltration bores 7 can be replaced by a retaining object 6 which is a recessed pit provided with a suitable infiltration material, most often sand and gravel.

Industrial usability

This technical solution can be used wherever there is a risk of flooding and a suitable landscape profile with the possibility of building ramparts for retaining excess water and absorbing it through infiltration boreholes or containment objects, where flood wave volumes and groundwater abundance are handled in a convenient morphological logic places, using already existing retention and free space underground.
