Definitions

  • the present invention is related to an anchoring weight made of concrete for submarine pipelines made of plastics material, according to the preamble of the claims.
  • the achoring weight according to the present invention has a shape which has proved to be superior above known achoring weight shapes in connection with the torsion forces as well as the friction forces.
  • the anchoring weight according to the present invention will be digged into the sea bed by tranversal forces, thereby stabilizing the pipeline.
  • a weight is provided which gives a submerged pipeline a large stability in the transversal as well as the longitudinal direction of the pipeline.
  • Fig. 1 a section perpendicular to the longitudinal axis of the pipeline and Fig. 2 discloses an axial section of the weight disclosed in Fig. 1.
  • the anchoring weight according to the present invention is made in two equal parts 1 and 2 of concrete, such that they, when assembled, create substantially a square comprising protuding legs 5 as prolongations of the diagonals in the square.
  • the terminations of the legs are plane sufaces arranged perpendicular to the diagonals whereby the cross section of the legs is increasing from the end surfaces towards the connection point to the substantially square portion of the weight.
  • the inner, substantially semi circular cutouts of the weight blocks or parts comprise elastic bands 3 abutting the pipeline compensating possible unevennesses in the concrete structure.
  • Two weight block halves 1 and 2 are clamped together with bolts 4 through corresponding bolt holes in the parts 1 and 2, whereby the diameter of the bolt hole is made to correspond with the bolt dimension only in a portion of of the block adjacent the opposite block and the rest of the hole has a larger diameter, allowing the bolt head and the corresponding nut to be arranged at the shoulder at the point with smaller diametr, thereby to enable use of relatively short bolts 4.

Abstract

Bloc contrepoids d'ancrage en béton destiné à un pipeline sous-marin en matière plastique, comprenant deux moitiés identiques de bloc (1, 2) assujetties par des boulons (4), les blocs présentant dans une section transversale au sens longitudinal du pipeline une forme extérieure sensiblement carrée, des pieds de support (5) coniques dépassant extérieurement de la partie carrée du bloc contrepoids assemblé étant disposés sous forme de prolongements des diagonales du carré.
