Definitions

  • the invention relates to an erosion-protecting surface covering for laying out on the sea bed, coastal areas and other earth surfaces which are exposed to water, said covering comprising a mat with concrete blocks resting on the top side.
  • a covering is known, for example, from FR-A-2 411 269.
  • Erosion can arise during storms and floods, while harbours are exposed to a bottom erosion which occurs particularly in sailing channels, and at ferry ports where the ferries are so large that the propellers are only a few metres above the sea bed.
  • the providing of a resilient bush in at least the hole in the upper block prevents the formation of cracks and destruction of the blocks by powerful influence from the bolts by dimensional changes, frost and the like.
  • FIG. 1 a preferred embodiment of the covering according to the invention. It is built up of hexagon-shaped concrete blocks, as shown in flg. 4, which shows the upper block 1 seen from above, mounted on a mat 8.
  • the blocks comprise an upper block 1, which is shown in fig. 1, and a lower block 4, which is shown in fig. 2.
  • the blocks 1, 4 have plane upper and lower sides respectively, so that they can lie up against the flexible loom in the form of the mat 8.
  • the blocks 1 and 4 there are holes through which a bolt 6 with a bent-over head can be inserted with the bent head in a countersinking 5 in the bottom of the lower block 4.
  • the upper block 1 is provided with an elastic bush 2 of synthetic material or rubber for the absorption of possible stresses. As will appear from fig. 3, the parts are tightened together around the mat 8 by means of an eyebolt 7.
  • the underside of the lower block 4 is also made concave, and it can suck itself firmly to the bottom after the laying out. Furthermore, the upper block 1 is tapered upwards in order to reduce the resistance to current.
  • the blocks are made by being moulded in concrete, and can have a breadth of about 50 cm and thickness of about 15 cm.
  • the blocks 1 and 4 are rounded off 3 on the undersides along the side edges in order to make them more resistant to external influences.
  • staggered rows of blocks are secured to the mat, which can be of synthetic fibres or the like.
  • the mat can have a breadth of about 2.5 m and a length of about 6 m.
  • Such an assembled covering will have a weight of about 6,000 kg.
  • the laying out can be effected by suspension in a lifting arrangement comprising a yoke 10 with lifting lines 11 and a lifting cable 12 for a crane.
  • the mats 8a and 8b can be positioned in such way that they overlap each other, after which a diver can bore holes through the mats and place concrete blocks under and over the mats respectively as shown in the drawing.
