Definitions

  • the invention is related to a revetment for an embankment, bank and the like, comprising revetment elements which have parallel bottom and top surfaces and which are arranged according to rows which are positioned next to each other in transverse direction, said rows each extending in longitudinal direction, each revetment element being symmetric with respect to a line of symmetry and asymmetric with respect to a line of asymmetry which is perpendicular with respect to the line of symmetry, open spaces being enclosed between subsequent revetment elements of a row and between revetment elements of neighbouring rows .
  • a revetment of this type is disclosed in WO-A-97/43487.
  • Said prior art revetment has revetment elements the line of symmetry of which is generally oriented in the longitudinal direction of the rows.
  • the convexly respectively concavely shaped ends of said revetment elements offer the possibility to arrange the revetment elements according to curved patterns. Thereby, the contour of specific forms, such as of dikes, banks and the like can be followed.
  • the openings which are left free make the revetment less vulnerable with respect to water pressure from the backside of the revetment.
  • the revetment elements are all oriented similarly in the longitudinal direction, which offers only limited possibilities for arranging the revetment elements.
  • a further revetment of this type is disclosed in FR-A-2.657.638.
  • Said prior art revetment comprises modular construction elements or revetment elements the circumference of which is formed by circular forms.
  • One end of each revetment element has a convex circular shape, whereas the opposite end has a concave circular shape.
  • the sides of the elements have mixed concave/convex circular shapes.
  • This specific layout with circular shapes provides the possibility to arrange the elements next to each other, whereby a completely closed covering can be obtained.
  • Such revetment is less fit for protecting dikes, banks and the like, as the water pressure at the back of the revetment cannot escape and thus poses the risk of destroying the revetment.
  • the object of the invention is therefore to provide an improved revetment which can be applied in a more flexible way and which is suitable for applications wherein an embankment is saturated with water.
  • This object is achieved in that the lines of symmetry of the revetment elements are oriented in the transverse direction and in that the revetment elements which are arranged according to a single row have the same orientations with respect to their respective line of asymmetry.
  • the longitudinal direction or direction of the line of symmetry of the revetment elements is not coincident with the longitudinal direction of the row in question, but transverse with respect to said longitudinal row direction.
  • This offers specific advantages, which make it possible to adapt the revetment better to the form of the dike, bank or the like to be covered.
  • the revetment elements may all be arranged in the same way with respect to their longitudinal direction or line of symmetry, according to which they are pointing in the same direction with their asymmetric part.
  • the revetment elements may have a generally triangular shape.
  • the revetment elements may have a general T-shape.
  • the revetment elements may have a longitudinal section and a lateral section.
  • said lateral section is positioned symmetric with respect to the line of symmetry of the revetment elements. It is then quite well possible to obtain orderly rows with oppositely oriented revetment elements in neighbouring rows.
  • the lateral sections of neighbouring rows may protrude between each other in case the rows are shifted in longitudinal direction with respect to each other over half the longitudinal length of the revetment element.
  • the longitudinal section has a longitudinal side located opposite the lateral section, said longitudinal sides of the revetment elements of neighbouring series facing each other and/or contacting each other.
  • the longitudinal section may have opposite ends in longitudinal direction which are convexly shaped.
  • the longitudinal section may have a concavely shaped longitudinal side located opposite the lateral section.
  • the lateral section has a convexly shaped lateral end.
  • the lateral section has opposite sides, when seen in longitudinal direction, which are concavely shaped.
  • convex and concave shapes provide the revetment with openings which are desirable for preventing the build up of water pressure behind the revetment.
  • the concavely shaped opposite sides of the lateral section have a radius of curvature which is smaller than the radius of curvature of the concavely shaped longitudinal side of the longitudinal section.
  • each convexly shaped end of the longitudinal section may merge into a concavely shaped side of the lateral section.
  • the rows may be arranged with respect to each other in such a way that the lateral end of a revetment element of a series abuts the longitudinal sections of adjoining revetment elements of a neighbouring series.
  • the rows which form the rows may be laid according to several forms. According to a first possibility, the rows are rectilinear. Alternatively or additionally, the rows are curved according to a part of a circle.
  • the invention is furthermore related to a revetment element for a revetment according to any of the preceding claims, said revetment element being symmetric with respect to a line of symmetry and asymmetric with respect to a line of asymmetry perpendicular with respect to the line of symmetry.
  • a revetment element of this type is also disclosed in FR-A-2.657.638.
  • Said prior art revetment element has limitations as highlighted before with respect to the build up of water pressure behind the revetment which is obtained by means of revetment elements.
  • the revetment element has a longitudinal section and a lateral section, said lateral section being positioned symmetric with respect to the line of symmetry of the revetment elements.
  • the lateral section is symmetric with respect to the line of symmetry of the revetment elements.
  • the revetment element has a generally triangular shape or a general T-shape.
  • Figure 1 shows a top view of the revetment consisting of rectilinear rows of revetment elements.
  • Figure 2 shows a top view of the revetment consisting of slightly curved rows of revetment elements.
  • Figure 3 shows a view in perspective of the revetment element according to the invention.
  • each revetment element 1 comprises a top face 4, a bottom face 5 and a circumference 6 which stretches all around the revetment element 1 and which extends between the top face 4 and the bottom face 5.
  • said top face 4 and said the bottom face 5 are oriented parallel.
  • the revetment elements 1 comprise a longitudinally extending section 7 as well as a transversely extending section 8. Both said longitudinally extending section 7 and said transversely extending section 8 are symmetrical with respect to the line of symmetry 9 as shown in figure 3. Furthermore, the revetment element 1 has a line of asymmetry 10 which line is shown in figure 1 as well.
  • the revetment element 1 in question has a general T-shape which is formed by said longitudinal section 7 and the transverse section 8. Said longitudinal section 7 has opposite ends 11,12 in longitudinal direction which are convexly shaped. Furthermore, the longitudinal section 7 has a longitudinal side 13 opposite the lateral section 8, which longitudinal side 13 has a concave shape.
  • the lateral section 8 has a convexly shaped lateral end 14. Moreover, the lateral section 8 has sides 15, 16 which are located opposite each other when seen in longitudinal direction, which sides have a concave shape.
  • the convexly shaped end 14 of the lateral section 8 merges smoothly into said concavely shaped sides 15, 16. Furthermore, said concavely shaped sides 15, 16 merge into the corresponding convexly shaped ends 11, 12 via the respective transitions 17, 18.
  • the neighbouring rows 2 respectively 3 are shifted with respect to each other in the longitudinal direction, over a distance which is about equal to half the longitudinal dimension of the longitudinal section 7. Furthermore, the convexly shaped ends 11, 12 of the longitudinal sections 7 abut each other. Also, the convexly shaped ends 14 of the lateral sections 8 abut onto the longitudinal sections 7 of the revetment elements of a neighbouring row, about at the location of the transitions 17, 18 of the concavely shaped sides 15, 16 and the convexly shaped ends 11, 12 of the neighbouring revetment elements of a neighbouring row.
  • pairs of neighbouring rows 2, 3 which are characterised by their longitudinal sides 13 lying against each other, have revetment elements 1 which are shifted with respect to each other over a distance which is different from half the length of the longitudinal section 7. This difference is caused by the curvature of the rows. Nevertheless, also in this arrangement open spaces 19,20 are formed, and also open spaces 21 between pairs of abutting longitudinal sides 13.
