Abstract

Det omtales en anordning ved pæleomslag omfattende en bøyelig plate (2) med en parallellogramform med stive men ikke fullstendig faste elementer (3) langs et par mot- stående kanter som rager ut fra platesiden for å avdekkes. Denne siden omfatter også fleksible ribber eller vinger (4) parallell til disse elementene (3), som når de vikles rundt en pæle (1) presses og festes sammen, som derved presser disse elementene til en spiralformet sammenstilling, lik til den inntatt av ribbene eller vingene (4). Vann som strømmer forbi pælen avledes mot den langsgående retningen til pælen, som motvirker en tendens til virvelpåvirket vibrasjon.A device is described by pile cover comprising a flexible plate (2) having a parallelogram shape with rigid but not completely fixed elements (3) along a pair of opposing edges projecting from the plate side to be uncovered. This side also includes flexible ribs or wings (4) parallel to these elements (3) which, when wound around a pile (1), are pressed and secured together, thereby pressing these elements into a helical assembly, similar to that taken up by the ribs. or the wings (4). Water flowing past the pole is diverted towards the longitudinal direction of the pole, which counteracts a tendency for vortex-induced vibration.
