Definitions

  • the present invention relates by way of novel industrial product, to blocks or like devices for protecting works, whether fixed or floating, against the detrimental action or impact of moving liquid masses.
  • jetties and the like have been protected against the attack of waves by means of blocks so disposed in relation to the work to be protected that they produce a certain dispersion of the wave impact energy.
  • the conventional defense method consisted in transporting these blocks, mostly rocks, to the site, placing them at the base of the work, and disposing them more or less at random.
  • the present invention provides a defense block of any suitable and preferably mouldable material, such as concrete (reinforced or not), resin and mineral fibre compounds, etc., said block being characterised essentially in that it comprises two convergent elongated elements constituting a kind of V directed toward the wavefront to be deadened, said V being connected to at least one complementary elongate element adapted to seat the complete block on the ground.
  • a defense block of any suitable and preferably mouldable material, such as concrete (reinforced or not), resin and mineral fibre compounds, etc.
  • the V comprising said pair of convergent elements may be more or less inclined to the wavefront to be de adened and the angle measured between the plane containing said pair of V-forming elements and the third or seating element of the block may vary according to the specific application contemplated.
  • the free ends of the component elements of the protection or defense block according to this invention may advantageously comprise means for permitting the mutual tangling up of blocks disposed in a row line for constituting a defense structure.
  • These'means may advantageously consist of protrusions, projections, acornshaped ends, or the like, having any suitable configuration.
  • FIG. 1 is a perspective view of a block according to this invention.
  • FIG. 2 is a view similar to FIG. 1 but showing an assembly or row comprising a plurality of blocks disposed in line.
  • the defense block according to this invention which may advantageously be formed by moulding from concrete (preferably reinforced concrete) or other compounds, comprises three main elongated elements a, b and 0 having any suitable cross-sectional configuration. Elements a and b converge to constitute a kind of V but lie either in a common plane or in different planes.
  • element b in the form of embodiment illustrated is connected to a third element c of which the essential function is to seat the V a b on the ground.
  • the direction of this third element 0 in relation to the plane of said V or to the plane of each component element thereof is immaterial or at least subordinate to the specific conditions to be met for erecting a defense system intended for the protection of a work, structure or construction by assembling a plurality of blocks according to this invention.
  • the free ends of the V-forming elements a and c may comprise means for interlocking a plurality of juxtaposed blocks.
  • These means may consist, as in the example illustrated in FIG. 2, of projections or protrusions a,, C having any suitable shapes and dimensions, for example a substantially frustoconical shape as shown.
  • blocks By using a plurality of blocks according to the present invention it is possible to erect defense lines or systems for protecting any work against the detrimental or impact action of moving liquid masses, along any possible contour.
  • These blocks may be disposed at random or disposed in rows in a vertical plane, or along horizontal lines as shown in FIG. 2, or'in rows disposed at an angle with respect to the front line of the work to be protected. Any desired combinations of these various arrangements may of course be envisaged.
  • a block for protecting floating or fixed works such as piers, seawalls, jetties and the like against action of moving liquid masses which comprises a pair of convergent elongated elements which are connected together only at their ends in an inverted V-formation, the second end of one of said elements being free, a complementary elongated member connected at one end only to the second end of the other of said convergent elements and extending laterally therefrom in one direction only in position to act in cooperation with said free end of said one element to seat the composite block on an underlying supporting surface, said pair of elements providing an open area sufficient to receive the complementary member of an identical block in interengaging adjacent relationship.
  • a block as claimed in claim 1 in which said pair of elements are formed to lie in an upstanding plane which is inclined at an angle to the wave front to be deadened when a series of said blocks are interengaged in a line substantially paralleling the wave front.
