Definitions

  • the present invention relates to a scour protection for an underwater bottom extending alongside a quay wall.
  • the invention further relates to a method for providing such scour protection.
  • Marine transport is ever increasing, both in quantity and size.
  • the last decade has seen developments in the shipping industry characterized by an increase in capacity.
  • Vessels are becoming larger and larger in order to be able to carry as much load as possible.
  • the increasing size of freight carriers and cruise ships has an important impact on harbor infrastructure, as docking basins need to be made deeper and quay walls stronger.
  • the larger vessels presently being developed are equipped with far more power than known hitherto.
  • the flow velocities against the quay walls and the harbor underwater bottom in front of the quay wall that are associated with the larger and more powerful propellers used on these vessels are anticipated to increase at such level that important damage may be caused to the quay walls and harbor underwater bottoms in particular. This damaging effect becomes more of a problem since modern vessels tend to have secondary propulsion systems such as bow and stern thrusters in order to increase their maneuverability, in particular while berthing.
  • Scour protection of underwater bottoms in harbors is known.
  • Existing scour protection at the toe of a quay wall may comprise a granular protection, to which may be added liquid asphalt mastic for additional strength.
  • Other known scour protection comprises mattresses of concrete blocks, rock or fibrous stone asphalt. These mattresses are easily applied to an underwater bottom, and for most applications provide sufficient strength, among other factors due to the flexible nature of a mattress. These materials however may not always provide adequate protection, or may not be available at the site.
  • FR-A-2 125 826 discloses a scour protection according to the preamble of claim 1 and a method for providing a scour protection according to the preamble of claim 16.
  • the above aim is provided by a scour protection for an underwater bottom alongside a quay wall in accordance with claim 1.
  • the scour protection of the invention comprises a foundation/leveling layer of rocks with a size distribution conforming to 100 ⁇ D n50 ⁇ 225 mm, and a plurality of prefabricated reinforced concrete slabs, adjacently positioned on top of the foundation/levelling layer and leaving a gap between edges of the slabs. It has turned out that a foundation/leveling layer in accordance with the invention provides a reliable and adequate support for the concrete slabs, and that the gap between edges of the slabs is instrumental in the long term protection offered by the invention.
  • the known classically used scour protection in the form of mattresses or granular protection requires large and heavy rocks up to 1-5 tons to withstand the typical thrust forces generated by a vessel. These rocks may not be readily available and further need to be applied in rather thick layers. This reduces the maximum available water depth alongside the quay wall.
  • the scour protection of the present invention does not have this drawback.
  • Known granular protection may also need accurate installation and leveling.
  • the scour protection thickness and density thus obtained is rather arbitrary and depends to some extent on the experience of the crane driver. Quality control tests performed upon completion of the works by the client or the contractor, in particular measurements of minimal thickness and density may result in a wide and undesirable variation.
  • the scour protection of the present invention does not have this problem and provides an accurate thickness and density to the scour protection. This allows to accurately defining the depth of the underwater bottom.
  • the foundation/leveling layer comprises rock with the claimed size distribution, whereby the wording rock may encompass any granular material such as rocks and/or stones, either natural and/or man-made.
  • the gap width between edges of the slabs may be chosen according to the selected size distribution of the rocks of the foundation/leveling layer.
  • a particularly preferred embodiment of the invention provides a scour protection wherein the gap width ranges from 10-100 mm, more preferably from 20-90 mm, and most preferably from 30-60 mm. The preferred embodiments help preventing washing out of underwater bottom layers below the slabs, and add to the stability of the scour protection.
  • the gaps between the concrete slabs should be present along one edge of each of at least two slabs, preferably along two edges of each of at least three slabs, more preferably along three edges of each of at least four slabs, and most preferably along four edges of each of at least five slabs.
  • the gaps may be present along edges that extend substantially parallel to an alongside direction of the quay wall, and/or may be present along edges that extend substantially perpendicular to the alongside direction of the quay wall.
  • the gap width between slabs is preferably a constant but may vary along an edge of two adjacently positioned slabs, preferably within 50% of the average gap width, more preferably within 20% of the average gap width, and most preferably within 10% of the average gap width.
  • the scour protection according to the invention advantageously allows maximizing the available water depth alongside the quay wall. It has turned out that the average thickness of the foundation/levelling layer and of in particular of the concrete slabs may be selected much smaller than with the known granular scour protection for instance.
  • a scour protection is provided wherein the slabs have a thickness ranging from 200-500 mm, more preferably from 275-425 mm, and most preferably from 325-375 mm. These preferred thicknesses provide the required protection against erosion, and further allow handling the slabs while positioning them on an underwater bottom.
  • An important advantage of the invented scour protection relates to an embodiment wherein concrete slabs are provided onto the foundation/leveling layer without requiring mutual connection of slabs. This facilitates replacement of a damaged slab by another slab.
  • the scour protection in accordance with the invention requires a gap between edges of the concrete slabs.
  • an embodiment relates to a scour protection wherein edges of the slabs are provided with distance holders or spacing lugs.
  • the spacing lugs may be separate or may be integral to the slab, and can be made from concrete, wood, rubber or another polymer, metal, and other suitable materials.
  • the spacing lugs or distance holders are instrumental in maintaining the required gap between slab edges.
  • the invented scour protection comprises a foundation/leveling layer of rocks with a size distribution conforming to 100 ⁇ D n50 ⁇ 225 mm.
  • D n50 is meant the nominal rock size that is exceeded by 50 wt.-% of the rocks.
  • Other useful embodiments of the invention provide a scour protection wherein the size distribution of the rocks conforms to 100 ⁇ D n50 ⁇ 185 mm, more preferably to 100 ⁇ D n50 ⁇ 155 mm, and most preferably to 110 ⁇ D n50 ⁇ 130 mm.
  • a scour protection is provided wherein the size distribution of the rocks is selected such that at most 10 wt.-% of the rocks has a size ⁇ 100 mm, and/or at most 10 wt.-% of the rocks has a size > 225 mm. In a particularly useful embodiment, at least 80 wt.-% of the rocks has a size between 100-225 mm.
  • the foundation/leveling layer serves to support the concrete slabs, and distributes the forces to the underlying soils.
  • a scour protection is provided wherein the foundation/levelling layer is level to within 200 mm, and more preferably to within 100 mm.
  • the foundation/leveling layer may be horizontal but may also have a slope exhibiting an angle with the horizontal direction, whereby the angle may be between 0-40 degrees, more preferably between 0-30 degrees, and most preferably between 0-20 degrees.
  • the scour protection according to the invention may be provided at any depth under water.
  • a scour protection is provided wherein at least some of the slabs are provided at a depth of at least 15 m, more preferably at least 20 m, and most preferably at least 25 m.

  • a practical embodiment of the invention provides a scour protection wherein the slabs have a lateral dimension of at least 3.5 m, more preferably at least 6 m, and most preferably at least 7 m.
  • a preferred scour protection comprises at least some slabs having a size of 8 x 8 x 0.35 m, with a variation of at most 40% of each dimension, more preferably at most 30% of each dimension, and most preferably at most 20% of each dimension.
  • the scour protection may extend in a transverse distance perpendicular to the quay wall over 1-10 meters only, over at least 10 meters, or over more than 100 m.
  • the scour protection may extend in a longitudinal direction parallel to (alongside) the quay wall over a few meters only, preferably over more than 100 m, and more preferably over more than 1 km.
  • the invention further provides an embodiment of a scour protection wherein the slabs are provided with a number of holes that extend from a front surface of the slabs to a back surface thereof.
  • the holes interact with the gaps between the slabs in preventing uplifting forces that may destabilize the slabs.
  • the holes are further instrumental in facilitating the placement of the slabs onto an underwater bottom.
  • the number of holes in the slabs may be chosen within a large range.
  • the number of holes in one slab ranges from 10-100, more preferably from 20-90, and most preferably from 30-80.
  • a preferred hole density ranges from 0,5 to 5 holes per m 2 , more preferably from 0,8 to 3 holes per m 2 , and most preferably from 0,9 to 2 holes per m 2 .
  • a cross-dimension of the holes (for instance the diameter in case of cylindrical holes) may be chosen within large ranges but is preferably selected between 20-200 mm, more preferably between 40-150 mm, and most preferably between 50-100 mm.
