Description
I Når rørledninger av plast, gummi eller annet materiale legges ned som sjoledninger, dvs. på bunnen av sjoer eller vassdrag, for-ankres de oftest med stopte betongvekter. I When pipelines made of plastic, rubber or other material are laid as sea pipelines, i.e. on the bottom of lakes or waterways, they are most often anchored with stopped concrete weights.
Foreliggende oppfinnelse vedrdrer en slik betongvekt for sjoledning, omfattende to deler som er utformet med komplementære uttagninger for deri å oppta ledningen mellom seg med et elastisk sammenpressbart mellomlegg anbragt mellom delene og ledningen, samt organ for sammenspenning av delene omkring ledningen. Slike betongvekter er tidligere kjente, og sammenspenningen av The present invention relates to such a concrete weight for sea wire, comprising two parts which are designed with complementary recesses in order to receive the wire between them with an elastically compressible spacer placed between the parts and the wire, as well as means for clamping the parts around the wire. Such concrete weights are previously known, and the compression of
de to deler tilveiebringes i den kjente utforelse ved hjelp av gjennomgående bolter, som går gjennom delene på tvers av skillefugen mellom dem. Ved sammenspenningen av delene tjener det elastisk sammenpressbare mellomlegg til å skåne den av betongvekten omsluttede ledning, slik at ikke den oftest grove overflate på betongvekten forårsaker skader på ledningsmaterialet. the two parts are provided in the known embodiment by means of through bolts, which pass through the parts across the separation joint between them. When the parts are clamped together, the elastically compressible spacer serves to protect the cable enclosed by the concrete weight, so that the usually rough surface of the concrete weight does not cause damage to the cable material.
Ulempen med denne type betongvekter er at boltene raskt rusterThe disadvantage of this type of concrete weights is that the bolts quickly rust
i stykker. Spesielt i sjovann eller annet aggressivt vann er boltene fullstendig i stykker rustet og må skiftes efter noen få år. Dette inntreffer til og med hvis boltene utfores av rustfritt syrefast stål, som dessuten er et dyrt materiale. broken. Especially in freshwater or other aggressive water, the bolts are completely rusted and must be replaced after a few years. This occurs even if the bolts are lined with stainless acid-resistant steel, which is also an expensive material.
For eliminering av denne ulempe er en betongvekt for sjoledningFor the elimination of this disadvantage is a concrete weight for sea line
av det foran angitte slag gitt de karakteristiske trekk ifolge krav 1, idet det elastisk sammenpressbare mellomlegg anvendes ikke bare til å skåne ledningsmaterialet men også til å opp-rettholde den for sammenholdingen av betongvektens to deler nodvendige spennkraft. of the type stated above given the characteristic features according to claim 1, the elastically compressible spacer being used not only to spare the cable material but also to maintain the tensile force necessary for the cohesion of the two parts of the concrete weight.
Til nærmere forklaring av oppfinnelsen skal en utforelse avxFor further explanation of the invention, an embodiment of x
denne beskrives nærmere i det efterfolgende under henvisning til tegningen, hvor this is described in more detail below with reference to the drawing, where
fig. 1 er et tverrsnitt av en sjoledning med en omkring denne anbragt betongvekt ifolge oppfinnelsen samt tilhorende sammen-spenningsorgan, for sammenspenningen av betongvekten omkring ledningen, fig. 1 is a cross-section of a sea line with a concrete weight placed around it according to the invention as well as the associated tensioning device, for the tensioning of the concrete weight around the line,
i fig. 2 er et planriss av betongvekten og sammenspenningsorganene, likeledes for sammenspenningen, in fig. 2 is a plan view of the concrete weight and the clamping devices, likewise for the clamping,

fig. 4 er et planriss av betongvekten ifolge fig. 3.fig. 4 is a plan view of the concrete weight according to fig. 3.
Den på tegningen viste stopte betongvekt omfatter to halvdeler 1'OA og 10B, som har en halvsylindrisk uttagning 11 for, når de legges sammen med disse uttagninger vendt mot hverandre, å oppta en rorledning 12 av plast, gummi eller annet materiale med et elastisk sammenpressbart mellomlegg 13 av gummi eller plast anbragt mellom de to vekthalvdeler og rorledningen. Dette mellomlegg er fortrinnsvis festet på overflaten av ut-tagningen 11 i den tilhorende halvdel av betongvekten ved frem-stillingen av denne for å lette og forenkle montasjearbeidet, når vekten skal anbringes på rorledningen. Når mellomlegget 13 ikke er sammentrykket, har skillefugen 14 mellom vekthalvdelene form av en forholdsvis bred spalte, slik det fremgår av fig. 1. På motsatte sider av vektdelene er det anordnet spor 15, som forloper på tvers av skillefugen 14 og i de fra skillefugen vendte ender danner hakeformede uttagninger 16. The stopped concrete weight shown in the drawing comprises two halves 1'OA and 10B, which have a semi-cylindrical recess 11 for, when placed together with these recesses facing each other, to accommodate a rudder line 12 of plastic, rubber or other material with an elastically compressible spacer 13 of rubber or plastic placed between the two weight halves and the rudder cable. This spacer is preferably attached to the surface of the recess 11 in the corresponding half of the concrete weight during its manufacture in order to facilitate and simplify the assembly work, when the weight is to be placed on the rudder line. When the intermediate layer 13 is not compressed, the separation joint 14 between the weight halves has the form of a relatively wide gap, as can be seen from fig. 1. On opposite sides of the weight parts there is a groove 15, which runs across the separation joint 14 and forms hook-shaped recesses 16 at the ends facing away from the separation joint.
To U-formede boyler 17 med midtparti 18 og hakeformede grener 19 er utformet for å passe i sporene 15 og uttagningene 16 men Two U-shaped boilers 17 with a central part 18 and hook-shaped branches 19 are designed to fit in the grooves 15 and the recesses 16 but
er således dimensjonert med hensyn til midtpartiets lengde,is thus dimensioned with regard to the length of the central part,
at betongvektens to halvdeler må trykkes sammen omkring rorledningen 12 under- utjevning av den brede spalte i skillefugen, for at boylene skal kunne fores inn i sporene og uttagningene. Denne sammentrykking av vekthalvdelene tilveiebringes ved hjelp av donkraft eller annet hensiktsmessig verktoy, hvorved det elastisk sammentrykkbare mellomlegg 13 presses sammen mellom that the two halves of the concrete weight must be pressed together around the rudder line 12 during leveling of the wide gap in the separation joint, so that the boyles can be fed into the grooves and recesses. This compression of the weight halves is provided by means of a jack or other appropriate tool, whereby the elastically compressible spacer 13 is pressed together between
vekthalvdelene og rorledningen, slik at betongvekten blir til-strekkelig sammentrykket i tverretningen av skillefugen 14, for at boylene 17 uhindret skal kunne fores inn i sporene 15 og uttagningene 16. Derefter avlastes trykket på vekthalvdelene, hvorved mellomlegget 13 igjen ekspanderer og presser vekthalvdelene ut fra roret, slik at boylene vil sitte sikkert på plass the weight halves and the rudder line, so that the concrete weight is sufficiently compressed in the transverse direction of the separation joint 14, so that the boyles 17 can be fed unhindered into the grooves 15 and the recesses 16. Then the pressure on the weight halves is relieved, whereby the spacer 13 again expands and pushes the weight halves out from the rudder, so that the boyles will sit securely in place
j ved det formbundne inngrep mellom de hakeformede grener 19 og de hakeformede uttagninger 16 under det av mellomlegget utovede trykk. Derved holdes de to -vékthalvdeler sikkert sammen omkring rorledningen på den måte som er vist i fig. 3. j by the form-bound engagement between the hook-shaped branches 19 and the hook-shaped recesses 16 under the pressure exerted by the intermediate layer. Thereby, the two weight halves are securely held together around the rudder line in the manner shown in fig. 3.
Boylene 17 er fortrinnsvis utfort av armert betong, men annet materiale kan selvsagt komme på tale. Det gjelder dog å velge et fullstendig korrosjonsbestandig materiale, slik at man ikke behover frykte samme ulempe som ved de kjente betongvekter. Ved betongvekten ifolge oppfinnelsen har man imidler-tid storre muligheter når det gjelder valg av materiale til sammenspenningsorganene enn hva angår vanlige bolter. The buoys 17 are preferably made of reinforced concrete, but other materials can of course be used. However, it is important to choose a completely corrosion-resistant material, so that you do not have to fear the same inconvenience as with the known concrete weights. With the concrete weight according to the invention, however, one has greater possibilities when it comes to the choice of material for the clamping elements than with regard to ordinary bolts.
Til slutt skal. nevnes at boylene naturligvis kan være flere enn to og kan være utformet på annen måte enn som vist her for oppnåelse av det nodvendige inngrep mellom vekthalvdelene og boylene under innvirke av det elastisk sammenpressbare mellomleggs trykk. Finally shall. it is mentioned that the boyles can of course be more than two and can be designed in a different way than shown here to achieve the necessary engagement between the weight halves and the boyles under the influence of the pressure of the elastically compressible spacer.
