Definitions

  • the subject of the invention a method of protecting a soil from erosion, in particular, from the erosion caused by rainwater and wind, as well as an equipment set to implement such soil protection
  • the purpose of the invention is to achieve an effective, cheap and easy to implement method of protecting the soil from erosion.
  • a method according to the invention relies on that on the surface to be protected is placed a geotextile of a basis weight of 200 to 500 g/m 2 and containing plant seeds in its structure in amount ranging from 10 to 20% of weight. Then this geotextile is covered by a spatial geogrid made of a set of plastic strips of thickness ranging from 1 to 7 mm. In the set each of the strips is permanently connected to the adjacent strip at regular distances, advantageously every 340 mm, forming spatial cells of the sizes ranging from 200 to 500 cm 2 and with a height of side walls ranging from 20 to 50 mm. Next, the spatial geogrid is-fixed to the ground by anchors and the spatial cells are filled with humus.
  • a biodegradable geotextile or a geosynthetic geotextile can be used as the geotextile.
  • the plastic strips forming the geogrid are perforated.
  • the anchors have a form of a rod bent at an angle of 180 degrees, advantageously of a rod of a diameter of 8 mm.
  • the solution according to the invention enables rapid, effective and low-cost protection from erosion of all types of land surfaces such as embankments, ditches and flood embankments. Additional advantages of the solution are: possibility of conducting ground works even before and after the growing season, getting almost 100% of biologically active ("green") surface, a large capacity to keep the seeds in the moisture which guarantees intense vegetation practically independent from the degree of the land slope.
  • Fig. 1 shows a vertical section of the slope protected using the method according to the invention.
  • Fig.2 shows a perspective view of an exemplary spatial geogrid used in the process of realisation of the invention.
  • Fig. 3 depicts the top view of the anchored geogrid prepared to be filled with humus.
  • a line was made on the crown of the scarp, at a distance of 50 cm from the upper edge 2 of the scarp 1.
  • an anchoring ditch 3 of the depth of 30 cm was made.
  • end of the geotextile roll 4 of a width of 300 cm was placed.
  • end of the geotextile roll 4 was anchored in the ditch 3 and covered with soil.
  • the geotextile roll 4 was unrolled down to the foot of the scarp 1.
  • a bidegradable geotextile, made of a mixture of wool and cotton, of a basis weight of 250-300 g/m 2 in a dry state and containing grass seeds 5 inside, in the amount of about 10%-20% of weight. was used.
  • a typical spatial geogrid 6 was placed on the unrolled geotextile 4.
  • the geogrid used was of the type in which a single leaf was made of sixty high-density polyethylene strips 7 of a width of 25 mm and a length of 3500 mm, ultrasonically welded 8 together, passing one another every 340 mm. After unrolling such leaf on a surface, a cell structure that is obtained has a width of about 260 cm and contains the cells 9, each forming an area of about 300 cm 2 .
  • the upper edge of the geogrid 6 was anchored in said ditch 3 with the use of anchors 10 made of steel wire of the diameter of 8 mm, U-shaped with a height of 400 mm, or J-shaped anchors with a height of 500 mm.
  • the anchors 10 were placed in every second cell.
  • the adjacent patches of the spatial geogrid 6 are connected by the U-shaped anchors 10 placed in every adjacent cell 9.
  • the unrolled geogrid 6 patches, which are not situated on the edges, are fixed to the ground with the J-shaped anchors 11 using one anchor for each 1.5 square meter of the covered surface.
  • the ready-made equipment sets can be used which are adjusted to the specific slope through the choice of the basis weights of the geotextile 4 and the geogrid 6 parameters.
  • Such equipment set contains a designation of a number of square meters of a land to be covered, adjusted amount of the geotextile 4 and a number of the geogrid patches 6 as well as correct number of the U-shaped 10 and J-shaped anchors 11.
  • the set prepared for area of 100 m 2 of a typical embankments contains approximately 110 m 2 (4 rolls) of the geotextile 4 that is described above, four patches of the spatial geogrid 6 described above, ninety U-shaped anchors 10 and eighty J-shaped anchors 11.
