Definitions

  • the invention relates to a damping element, comprising a head part, neck part and foot part of concrete, adjoining one another in the longitudinal direction, wherein the cross section of the neck part transversely to the longitudinal direction is smaller than the cross section of the head part transversely to the longitudinal direction and is smaller than the cross section of the foot part transversely to the longitudinal direction, which foot part has a periphery and a base, which periphery extends narrowingly from the base in the longitudinal direction.
  • a damping element of this type is known, for example from Dutch patent
  • Damping elements can be used, for example, in water barriers in connection with the damping of the wave action. Between the mutually adjacent head parts of the damping elements openings remain, via which the water crashing against the water barrier can drain away. A significant damping effect is thereby obtained. The water which is thus collected can be evacuated via the system of channels which is formed between the mutually adjacent, narrower neck parts, whereby the damping is further promoted.
  • the upright sides ofthe foot parts are provided with the said shape which becomes somewhat narrower in the upward direction. Wedge-shaped gaps, which widen in the upward direction, are thereby formed between adjacent damping elements.
  • stone chippings, grit or gravel for example, can be received.
  • Such a material ensures that the foot parts are firmly stabilized relative to one another. As a result of the wedge shape of the gaps between the foot parts, a strong mutual clamping effect of the foot parts is thus obtained.
  • the damping elements are placed side by side on a dike body in large numbers, in rows running in two mutually perpendicular directions.
  • grabs are herein used, and also a plurality of damping efcments can be placed side by side at the same time.
  • the jaws of the grab are brought to act on the foot part of the damping elements.
  • the engagement on the foot part can be adversely influenced by the upwardly narrowing shape of that foot part.
  • the damping elements can move in the grab, in which case damage occurs to the neck part and to the transition between the neck part and the foot part.
  • An object of the invention is hence to provide a damping element which can. be handled in a more reliable manner by means of a grab.
  • a further object of the invention is to provide a damping element which rums less risk of being damaged as it is put in place by means of a grab.
  • Another object is to provide a damping element which in particular is suitable for being grabbed and placed side by side several at a time.
  • the damping element can be grabbed by the foot part on the gripping projection which is specially designed for this purpose. It is thus no longer necessary to grab the foot part on those parts of the foot which are tapered.
  • the engagement on the gripping projection enhances the reliability of the engagement.
  • a projection which has a gripping surface extending substantially parallel to the longitudinal direction is preferred.
  • the gripping projection can possess, for example, an adapted surface, having a surface structure which in particular is suitable for improving the friction between the jaws of a grab and the damping element at the point of
  • the gripping projection can extend over substantially the entire height of the foot part, though that is not necessary. Furthermore, and preferably, the gripping projection can have a width in the peripheral direction which width is an order of magnitude smaller than the peripheral dimension of the periphery.
  • the periphery of the foot part can have a plurality of corners, wherein a peripheral side extends between in each case two comers. At least one of the peripheral sides is provided with a gripping projection. In that case, the width of the gripping projection can also be an order of magnitude smaller than the length of a peripheral side, viewed in the peripheral direction.
  • the gripping projection can be located equidistant from both corners of the peripheral side.
  • These peripheral sides can be slightly convexly curved, such that the damping elements can also be positioned, somewhat twisted relative to one another about the longitudinal direction, in curvedly running paths.
  • Preference is for a damping element the foot part of which is quadrangular or rectangular, with the formation of two pairs of opposite peripheral sides; in that case, a gripping projection is respectively found on two opposite peripheral sides.
  • each damping element part can comprise two damping element parts, which abut each other according to an interface running parallel to the longitudinal direction.
  • damping element parts are identical.
  • each damping element part comprises a full peripheral side as well as two peripheral side halves bordering the full peripheral side on either side, wherein the gripping projections are then provided on the full peripheral side of the damping element parts.
  • the invention further relates to a damping element part for a damping element as described above, comprising a full peripheral side as well as two peripheral side halves bordering the full peripheral side on either side, and a gripping projection which is provided on the full peripheral side.

Abstract

La présente invention a trait à un élément d'amortissement (1) qui comprend, dans la direction longitudinale (16) et à proximité les unes des autres, une partie tête (2), une partie col (3) et une partie pied (4) en béton. La section transversale de la partie col (3), lorsqu'elle est vue transversalement par rapport à la direction longitudinale (16), est plus petite que la section transversale de la partie tête (2) d'un point de vue transversal par rapport à la direction longitudinale, et elle est plus petite que la section transversale de la partie pied (4) d'un point de vue transversal par rapport à la direction longitudinale. La partie pied (4) possède une périphérie (7) et une base, la périphérie s'étendant en se rétrécissant à partir de la base dans la direction longitudinale. Cette périphérie (7) comporte au moins une saillie de préhension (12) s'étendant dans la direction longitudinale, de telle sorte que l'élément d'amortissement peut être correctement saisi par une benne preneuse.
