Definitions

  • This invention concerns a method for constructing a steep embankment or slope.
  • various techniques are known for building steep slopes.
  • the known techniques stem from the wish to achieve stable slopes since, in many cases, for construction purposes or traffic related reasons it is necessary to execute a given embankment so steep that the embank- ment cannot be constructed solely with earth or gravel materials and would not in itself be stable enough to resist erosion for a longer period of time. Par ⁇ ticularly it cannot resist erosion due to precipitation, including rain showers, the effects of melting water etc.
  • Such an embankment must furthermore in certain cases fulfil specific requirements or wishes with regard to appearance, including vegetation, stone kerbing, wooden or facade coating.
  • An object of the present invention is to achieve a technique which eliminates the aforesaid drawback in the prior art, and particularly enables a more flexible adaptation and construction of an embankment on site and at the same time enables the construction of an embankment using a universal set of elements which may be produced with universal dimensions and combined on site accord ⁇ ing to a given required embodiment, i.e. corresponding to the embankment to be constructed.
  • an anchor element which in accordance with alternative embodiments may consist of an anchorage grid, an anchor peg or an anchor block as well as one or more anchorage braces or struts, a reinforcement may be constructed in an embankment, it being possible to construct said reinforcement on site and adapt it to the given specifications and requirements, including ad hoc adjustment.
  • a reinforcement may be constructed in an embankment, it being possible to construct said reinforcement on site and adapt it to the given specifications and requirements, including ad hoc adjustment.
  • the method according to this invention preferably further comprises a step wherein one or more layers of geo-net and one or more layers of geo-textiles which may be mutually interconnected or placed overlapping one another under or above the anchor element as well as preferably behind the front grid.
  • the front grid may constitute a component left in place after construction of the embankment and, depending on the specific use, it may be made from corrosion- resistant material or alternatively from non corrosion-resistant material. If the front grid is to remain intact as a reinforcement element in the embankment even after a long span of years, the front grid must naturally be made from corrosion- resistant material. In case of subsequent planting and thereby so to say natural reinforcement of the embankment built according to the method of the invention the front grid may be made from non corrosion-resistant material, the front grid corroding away after a period of time.
  • the method may, according to an alternative embodiment, further comprise the final step of removing the front grid after construction of the finished embankment, including any planting on the completed embankment.
  • Erecting of the front grid according to the method of the invention may take place in any suitable way, including fixing of the front grid by means of anchoring pegs driven down at the bottom edge of the front grid once it has been raised to the desired inclination in relation to horizontal and possibly temporarily supported and fixed by means of temporary anchor struts or the like.
  • a stable securing of the front grid is carried out by digging a trench prior to or during the erection of the planar front grid and erecting and securing the planar front grid in said trench using sand, gravel, concrete or a mixture thereof.
  • This invention also relates to a system for building a steep embankment, said system being adapted to carry out the method of the invention, and in accordance with the invention the system is characterized by comprising a planar front grid adapted to be positioned with an inclination corresponding to the completed embankment immediately adjacent the front of the completed embankment, an anchor element adapted to be placed in the earth formation behind the completed embankment and one or more anchor braces or struts adapted to connect and secure the front grid relative to the anchor element when the front grid is positioned with the said inclination and when the anchor element is placed in the earth formation.

  • the anchoring system according to the pres ⁇ ent invention may consist of an anchor grid, an anchor peg, an anchor block or the like or a combination thereof.
  • the system according to the present invention may be designed with a front grid made of corrosion resistant or, alternatively, non corrosion-resistant material.
  • the invention further concerns an embankment or slope which is constructed according to the teachings of the invention, and in which anchoring members have been placed for anchorage of the earth formation lying behind the embankment, said embankment in accordance with the invention being characterized in that a planar front grid is positioned within the embankment and having an inclination corresponding to that of the completed embankment, that in the earth formation behind the embankment an anchor element is placed, that between said front grid and said anchor element firm anchoring is provided by means of one or more anchor braces or struts which secure the front grid in relation to the anchor element and that possibly furthermore one or more layers of geo-net or one or more layers of geo-textiles have been inserted which may be mutually interconnected or placed overlapping each other under or over the anchor element and preferably also behind the front grid.

Abstract

Pour la construction d'une digue inclinée, on utilise une grille frontale plane (2) posée selon une inclinaison donnée correspondant à celle de la digue achevée et dans une position immédiatement contiguë à celle de la surface frontale de la digue une fois achevée. En un point de la levée de terre se trouvant derrière la digue achevée, on pose un élément d'ancrage (5), et entre la grille frontale (2) et l'élément d'ancrage (5) des barres d'ancrage fixes (4a, 4b) sont installées pour rendre la grille (2) solidaire de l'élément d'ancrage (5). De plus, on place ou insère de préférence une ou plusieurs couches de géo-net (7) sous ou sur l'élément d'ancrage (5) et derrière la grille (2). Enfin on comble la zone située derrière la grille (2) en recouvrant l'élément d'ancrage (5), pour constituer la formation de terre de la digue achevée. Ce procédé recourt à un système universellement applicable comportant une grille frontale plane, un élément d'ancrage et plusieurs barres ou entretoises d'ancrage, ledit système étant immédiatement applicable à une application donnée.
