Description
Foreliggende oppfinnelse vedrører en fremgangsmåte for å forhindre lekkasje fra sisterner, fortrinnsvis oljetanker, som er plassert under marknivå, ut i omkringliggende marksjikt og grunnvann. The present invention relates to a method for preventing leakage from cisterns, preferably oil tanks, which are placed below ground level, into the surrounding soil layer and groundwater.
I den senere tid er man blitt stadig mer oppmerksom på, hvilke alvorlige følger en lekkasje fra en nedgravd tank, for eksempel oljetank, kan få, dersom olje fra denne strømmer ut i omkringliggende marksjikt og blander seg med grunnvannet. I In recent times, people have become increasingly aware of the serious consequences a leak from a buried tank, for example an oil tank, can have if oil from this flows out into the surrounding ground layer and mixes with the groundwater. IN
visse land har disse konsekvenser allerede . rukket å føre til en strengere lovgivning med hensyn til utførelsen ved nedgrav-ing av tanker. certain countries have these consequences already. managed to lead to stricter legislation with regard to the performance when burying tanks.
Tross behovet for et bedre vern mot lekkasje fra nedgravde oljetanker o.l. har det imidlertid ikke fremkommet noen akseptabel løsning på problemet. Et forsøk på forbedring er gjort, ved at man på den plass under marknivået, hvor oljetanken eller olje-tankene skal plasseres, støper et kar med fall i én retning, hvori tanken eller tankene deretter legges ned. Denne fremgangs-gangsmåte stemmer således stort sett overens med den utførelse man allerede tidligere har benyttet for oljetanker over mark og i hus. Dessuten anbringes det i marken et rør som strekker seg ned i karet til det laveste parti. Ved en eventuelt olje-lekkasje er hensikten, at olje ikke skal nå utenfor karet, men i stedet strømme i retning mot røret og opp i dette, som der- Despite the need for better protection against leakage from buried oil tanks etc. however, no acceptable solution to the problem has emerged. An attempt at improvement has been made by casting a vessel with a slope in one direction in the place below ground level, where the oil tank or tanks are to be placed, into which the tank or tanks are then placed. This procedure is thus largely consistent with the design that has already been used in the past for oil tanks above ground and in buildings. In addition, a pipe is placed in the ground that extends down into the tub to the lowest part. In the event of an oil leak, the intention is that oil should not reach outside the vessel, but instead flow in the direction of the pipe and up into it, as there-
ved tjener til å indikere lekkasjen. by serves to indicate the leak.
Denne utførelsen er imidlertid ikke tilfredsstillende i praksis, siden det alltid foreligger risiko for at karets hel-ning på grunn av séfcninger i marken ikke forblir korrekt slik at utlekkende olje ikke når frem til indikeringsrøret på et tilstrekkelig tidlig stadium. Man kan også tenke seg, at tanken, som er omgitt av fyllmasser, korroderer i stykker på et så høyt plassert sted, at oljen har mulighet for å strømme utenfor karets However, this design is not satisfactory in practice, since there is always a risk that the slope of the vessel due to sedimentation in the ground does not remain correct so that leaking oil does not reach the indicator tube at a sufficiently early stage. One can also imagine that the tank, which is surrounded by filling materials, corrodes to pieces in such a high place that the oil has the opportunity to flow outside the tank
vegger direkte ut i grunnvannet. For å forhindre en slik følge, walls directly into the groundwater. To prevent such a consequence,
må man bygge karet med vegger som strekker seg et stykke over tanken, noe som gjør hele konstruksjonen omfattende og kostbar. you have to build the tank with walls that extend some distance above the tank, which makes the whole construction extensive and expensive.
Ved hjelp av oppfinnelsen har man skapt en enkel og pålite-lig løsning på dette problem. Det som kjennetegner fremgangsmåten ifølge oppfinnelsen fremgår av de etterfølgende kravene. With the help of the invention, a simple and reliable solution to this problem has been created. What characterizes the method according to the invention appears from the following claims.
I det følgende skal oppfinnelsen beskrives nærmere under henvisning til tegningene, hvor fig. 1-3 viser fremgangsmåten ifølge oppfinnelsen under utførelse i tre ulike stadier og fig. 4 en detalj i fig. 3 i større målestokk. In what follows, the invention will be described in more detail with reference to the drawings, where fig. 1-3 show the method according to the invention being carried out in three different stages and fig. 4 a detail in fig. 3 on a larger scale.
Fremgangsmåten ifølge oppfinnelsen utføres på følgende måte:. Man graver først ut en grop 1, hvor man har til hensikt å.plas-sere én eller flere tanker. På gropens 1 bunn og mot storparten av dens vegger legges deretter ut et tetningssjikt 2 som hensiktsmessig består av en plastmatte, for eksempel av den type som finnes i handelen under navnet Trocal (varemerke). På en side strekker tetningssjiktet 2 seg inntil videre et stykke opp av gropen 1. På bunnen av dette tetningssjikt 2 legges nå ut et lag 3 av sand og grus, hvilket tilsvarer det stadium som er anskueliggjort i fig. 1. The method according to the invention is carried out in the following way: One first excavates a pit 1, where one intends to place one or more tanks. On the bottom of the pit 1 and against the majority of its walls, a sealing layer 2 is then laid out, which suitably consists of a plastic mat, for example of the type found in the trade under the name Trocal (trademark). On one side, the sealing layer 2 extends for the time being a little way up the pit 1. At the bottom of this sealing layer 2, a layer 3 of sand and gravel is now laid out, which corresponds to the stage illustrated in fig. 1.
Etter dette senkes en eller flere sisterner eller tanker 4 ned i gropen 1 til anlegg mot gruslaget 3, og gropen fylles opp med fyllgrus 5 til et nivå 6 godt og vel over overkanten av de to tankene 4 som er vist i fig. 2. Heretter tappes ifølge oppfinnelsen vann ned i gropen 1 i såpass stor mengde at begge grus-og sanélagene 3 og 5 bløtes og vannivået 7 blir liggende et sted mellom tankenes 4 overkant og fyllgrusens 5 nivå 6. Endelig legges tetningssjiktet 2 utover grussjiktet 5 og lukkes tettende i alle skjøter, hvilket kan skje ved^varmeforsegling eller ved hjelp av et plasibindemiddel. Sisternene eller tankene 4 ligger således nå hermetisk innelukket i tetningssjiktet 2. Jord og sand 8 fylles deretter på opptil marknivå 9 ( se fig.3). After this, one or more cisterns or tanks 4 are lowered into the pit 1 to abut against the gravel layer 3, and the pit is filled up with fill gravel 5 to a level 6 well above the upper edge of the two tanks 4 shown in fig. 2. Thereafter, according to the invention, water is drained into the pit 1 in such a large amount that both the gravel and sanitary layers 3 and 5 are soaked and the water level 7 remains somewhere between the upper edge of the tank 4 and the level 6 of the fill gravel 5. Finally, the sealing layer 2 is laid beyond the gravel layer 5 and is closed tightly in all joints, which can be done by heat sealing or with the help of a plastic binder. The cisterns or tanks 4 are thus now hermetically enclosed in the sealing layer 2. Soil and sand 8 are then filled up to ground level 9 (see fig.3).
Dersom man oppbevarer olje i tankene 4 og det oppstår lekkasje i noen av dem, vil oljen, uavhengig av om lekkasjen dannes oventil, på siden eller nederst på tanken, ikke strømme ut av denne, men vann i stedet trenge inn i tanken. Man kan med et vannindikeringsrør 10 deretter snart konstatere, at det har skjedd et gjennombrudd i tankveggen og foreta forholdsregler for repa-rasjon eller utbytting av tanken uten at det risikeres at olje If you store oil in the tanks 4 and a leak occurs in any of them, the oil, regardless of whether the leak is at the top, on the side or at the bottom of the tank, will not flow out of it, but water will instead enter the tank. With a water indicator tube 10, one can then soon ascertain that a breakthrough has occurred in the tank wall and take precautions for repair or replacement of the tank without the risk of oil

Som en videreutvikling av fremgangsmåten ifølge oppfinnel- As a further development of the method according to the invention
sen kan man føre et rør 11 ned gjennom tetningssjiktet 2 og forbinde det tettende med dette. I fig. 4 er det vist en hensiktsmessig måte, som er prinsipielt kjent fra tidligere. En metallplate 12 med et plastsjikt 13 sveises fast til røret 11 then you can lead a pipe 11 down through the sealing layer 2 and connect the sealing to this. In fig. 4 shows an appropriate way, which is in principle known from earlier. A metal plate 12 with a plastic layer 13 is welded to the pipe 11
og limes med plastsjiktet vendt mot,tetningssjiktet 2 fast til dette. På utsiden av rørgjennomgangen anbringes hensiktsmessig en tetningsmansjett 14. Også røret 10, påfylningsrør 15 og pumpe-rør 16 er utført med slike tetninger, selv om disse for enkel- and glued with the plastic layer facing, the sealing layer 2 fixed to this. A sealing sleeve 14 is suitably placed on the outside of the pipe passage. The pipe 10, filling pipe 15 and pump pipe 16 are also made with such seals, although these are too simple
hets skyld er utelatt på tegningen. his fault is omitted from the drawing.
Ved hjelp av røret 11 kan man kontrollere vannivået 7 og With the help of the tube 11, the water level 7 can be checked and
ved behov fylle på vann. Som en fordelaktig utførelsesform kan man også tenke seg å koble røret 11 til en vannpumpe 17 og ved hjelp av denne skape et visst overtrykk innenfor tetningssjiktet 2. Dette gir ennå større sikkerhet for, at det overhode ikke kan komme olje ut gjennom en tankvegg ved en eventuell lekkasje i denne. if necessary, top up with water. As an advantageous embodiment, one can also imagine connecting the pipe 11 to a water pump 17 and using this to create a certain excess pressure within the sealing layer 2. This provides even greater certainty that no oil can escape through a tank wall at all possible leakage in this.
