CS212445B1 - Prefabricated permeable fortification of slopes and water bodies on a textile filter - Google Patents

Abstract

The purpose of the invention is to mechanize the heavy fortification of slopes and watercourses with permeable paving in one work operation together with a filter subgrade even below the groundwater level. The stated purpose is achieved by the prefabricated permeable fortification of slopes and watercourses on a textile filter according to the invention by proposing a placement on the slope with oblique placement joints in the direction of the diagonal of the square prefabricates for square and triangular multi-hole prefabricated fortification tiles and by laying the fortification tiles together with the previously glued filter textile from below, cut to protrude beyond the dimensions of the fortification tile.

Description

The present invention relates to prefabricated permeable slope fortifications and water troughs which require filtration. layer to allow water to flow through the tiles without breaking its integrity.

The filter layer between the permeable pavement and the less permeable subsoil prevents the leaching of the soil during filtration processes of the external water or groundwater. The filter layer is made of gravel or technical textiles. The placement of gravel requires largely manual work, the fabric filter is sensitive to scratch damage. The establishment of filter layers is difficult when the subsoil is flooded.

The fastening bodies attached to the textile filter allow the provision of permeable fortifications of the required qualities. However, it requires an extremely strong fabric filter fabric, and due to the low weight of the fortification bodies, the fortification thus established resists only the low external water velocities.

Heavier fortifications, which have recently been made with larger concrete or reinforced concrete prefabricated panels, which are provided with one or more openings, are required for higher alignment speeds. The permeable fortification first requires the installation of a reliable filter layer.

These difficulties are overcome by the prefabricated permeable reinforcement of slopes and water troughs on the textile filter according to the invention, the essence of which is to translate the individual fortification plates and to store them.

The fortifications are square and triangular, prefabricated reinforced concrete and have a central pendant hole for mechanized placement as well as 3 other openings to increase throughput.

Prior to depositing, the fortifying thatch is provided with a textile filter from the bottom, optionally with a reinforcing fabric, which prevents the textile filter from deforming during installation. The pre-cut filter fabric is heavier than the reinforcing plate and overheats after gluing above its upper edges.

On the trimmed fabric provided with glue, if desired, together with the reinforcing fabric, individual reinforcing sheets are laid, whereby the textile filter is adhered from below, and with the diagonal lines of the square that produces a favorable aesthetic impression, but in particular a mat bond between the individual fastening plates. the resistance to the vanishing velocity of the external water is demonstrably improved compared to the placement of the cantilevered slabs in the direction of the water flow and perpendicular to this direction.

The placement of heavy prefabricated fortification plates together with a textile filter simplifies the mechanical installation of the fortification, which is also possible under water to a depth of sufficient visibility. Also, the flowing water does not prevent storage until it obstructs the direction of the heavy plates to the desired position.

In the accompanying drawing, an example of an embodiment of a prefabricated permeable fortification according to the invention is shown. 1 shows a multi-hole square prefabricated board with a fabric filter adhered; FIG. 2 is a multi-aperture triangular plate with a textile filter adhered; and FIG. 3 is a cross-sectional view of a slope and a bottom of a waterbed with a permeable fortress on the slope and a bottom of a waterbed on a fabric filter.

In prefabricated reinforced concrete that is, both in the square plate 6 and in the triangular plate 2, the suspension beam openings 6 are in the center of gravity. The thatch may have slightly bevelled edges 8. Along with the adhered textile fabric 6, respectively, on the reinforcing fabric 2, the fortification seams are deposited on the leveled surface of the slope 8.

The prefabricated permeable fortification laid according to the invention together with a textile filter is advantageous where good paving permeability and filter stability are required for more dynamic water effects such as drainage channels, water channels and reservoirs as well as frequent water level fluctuations or in the case of fortification of a strong sufic subsoil.

The work with the reinforcing plates according to the invention permits an advantageous mechanization of hooi even when the subsoil is flooded.
