146048146048

Den foreliggende opfindelse angår en fremgangsmåde til sletning af jordtanke ved opfyldning.The present invention relates to a method for erasing earth tanks by refilling.

Af miljøhensyn gælder der særlige regler for nedgravede tanke, f.eks. olietanke af stål. Sådanne jordtanke for 5 olie må maksimalt anvendes i 20 år, hvis de ikke er udstyret med katodisk beskyttelse eller anden godkendt beskyttelse imod udsivning af olie ved tæring som følge af korrosion. Myndighederne foreskriver ved sletning af olie-jordtanke enten opgravning af tanken eller udfyldning af 10 denne med et stabilt uorganisk materiale, f.eks. sand. Alternativt kan en jordtank slettes ved udstøbning med beton.For environmental reasons, special rules apply to buried tanks, e.g. steel oil tanks. Such earth tanks for 5 oil may be used for a maximum of 20 years if they are not equipped with cathodic protection or other approved protection against leakage of oil by corrosion due to corrosion. The authorities prescribe, when erasing oil-soil tanks, either excavating the tank or filling it with a stable inorganic material, e.g. true. Alternatively, a soil tank can be erased by concrete casting.

Langt det størtste antal af kondemnerede jordtanke er olietanke til private oliefyringsanlæg, dvs. det drejer sig hovedsageligt om mindre jordtanke på indtil 4.000 liters 15 rumfang. De nævnte miljøkrav med hensyn til maksimal alder på nedgravede olietanke af stål trådte i kraft i 1960, hvilket betyder, at virkelig mange jordtanke fra perioden før 1960 nu er faldet for nævnte aldersgrænse og følgelig må kræves slettet. De fleste af disse forældede jordtanke, der 20 som nævnt er mindre private tanke, er nedgravet i folks haver. Dette medfører selvsagt relativt store omkostninger for private tankejere; den største ulempe ved sletning eller fjernelse af private, nedgravede olietanke anses af de fleste at være de dermed forbundne "ødelæggelser" af 25 haver, indkørsler, terrasser og lignende udenomsarealer ved private ejendomme.By far the largest number of condensed earth tanks are oil tanks for private oil fired plants, ie. these are mainly small earth tanks of up to 4,000 liters of 15 volumes. The environmental requirements mentioned for maximum age on buried steel oil tanks came into force in 1960, which means that many earth tanks from the pre-1960 period have now fallen below that age limit and consequently must be deleted. Most of these outdated earth tanks, which 20 are smaller private tanks, are buried in people's gardens. This, of course, entails relatively high costs for private thought owners; the major disadvantage of the deletion or removal of private, buried oil tanks is considered by most to be the "devastation" of 25 gardens, driveways, terraces and similar outdoor areas in private properties.

Opfindelsen har til formål at angive en fremgangsmåde til sletning af jordtanke ved opfyldning, hvilken fremgangsmåde kan betyde en enkel, billig og for omgivelserne skån-30 som sletning af kondemnerede jordtanke.The invention has for its object to provide a method for deleting earth tanks by refilling, which can mean a simple, inexpensive and environmentally friendly deletion of condensed earth tanks.

Fremgangsmåden ifølge opfindelsen er ejendommelig ved, at man anvender et trykmedium til gennem en slange at transportere og udfylde jordtanken med fyldmaterialet fra en i af- 2 U0048 stand fra jordtanken anbragt trykbeholder, som forinden er tilført fyldmaterialet. Herved opnås en virkelig enkel, billig og for omgivelserne skånsom metode til sletning af jordtanke, idet udfyldning af tanken derved kan foregå uden el-5 ler med minimal gravearbejde ved jordtanken. TrykfyIdebeholderen kan under fyIdeoperationen være anbragt temmelig langt fra jordtanken, f.eks. helt uden for den berørte have eller ejendom. Hele fyldeoperationen kan udføres af en eller to personer i løbet af få timer, dvs. at fremgangsmåden ifølge 10 opfindelsen i forbindelse med mindre oliejordtanke kan betyde en minimering af omkostninger og god mulighed for skånsom påvirkning af jordtankens omgivelser.The method according to the invention is characterized in that a pressure medium is used to transport and fill through the hose the filling tank with the filling material from a pressure vessel located previously from the ground tank, which is previously supplied to the filling material. This results in a really simple, inexpensive and environmentally sensitive method for deleting earth tanks, as filling of the tank can thereby be done without or with minimal digging at the earth tank. During pressure operation, the pressure vessel can be located quite far from the ground tank, e.g. completely outside the affected garden or property. The entire filling operation can be performed by one or two people within a few hours, ie. that the method according to the invention in connection with smaller oil soil tanks can mean a minimization of costs and good opportunity for gentle influence on the environment of the soil tank.

Fortrinsvis kan ifølge opfindelsen jordtankens sædvanlige fyldestuds, anvendes til indblæsning af fyldmateriale, så-15 fremt fyldestudsen ikke er forbundet med et alt for langt og snørklet indfyldningsrør. Man kan dog også i tilfælde af, at indfyldningsrøret ikke er egnet ifølge opfindelsen skære en åbning foroven i jordtanken, idet man hensigtsmæssigt anvender en vinkelformet indføringsdyse, der kan bevæges således, 20 at fyldmaterialet fordeles i hele tanken. Der er her tale om en noget større arbejdsindsats, men der kan til gengæld opnås en effektiv fyldning. Der kan anvendes almindeligt groft sand som fyldmateriale - og det uden at sandet skal forbehandles på nogen måde, eksempelvis er det ikke nødvendigt at tørre 25 sandet overhovedet. Fortrinsvis indledes tanksletningen med tomsugning af jordtanken for fjernelse af restindhold af olie og eventuelt bundslam, men for at opnå større sikkerhed med skadelige virkninger fra resterne af tankindholdet, kan man ifølge opfindelsen hensigtsmæssigt iblande i det mindste den 30 første del af fyldmaterialet et olieabsorberende eller et olieneutraliserende materiale, fortrinsvis i pulverform.Preferably, according to the invention, the usual filler nozzle of the soil tank can be used for supplying filler material, provided that the filler nozzle is not connected to an overly long and snotty filling tube. However, it is also possible, in the case where the filling tube is not suitable according to the invention, to cut an opening at the top of the soil tank, suitably using an angular insertion nozzle which can be moved so that the filling material is distributed throughout the tank. This is a somewhat larger work effort, but in return an efficient filling can be achieved. Ordinary coarse sand can be used as a filler - and without the sand having to be pre-treated in any way, for example, it is not necessary to dry the sand at all. Preferably, the tank erasure is initiated by emptying the soil tank to remove residual oil content and possibly bottom sludge, but in order to obtain greater safety with detrimental effects from the residual tank contents, according to the invention it is convenient to mix at least the first part of the filler material with an oil absorbent or an oil absorber. oil neutralizing material, preferably in powder form.

Opfindelsen forklares i det følgende nærmere i forbindelse med tegningen, på hvilken 3 146048 fig. 1 er en principskitse til illustration af fremgangsmåden ifølge opfindelsen, medens fig. 2 viser en tryktank til brug ved udøvelse af opfindelsen.The invention will now be explained in more detail in connection with the drawing, in which FIG. 1 is a schematic drawing of an illustration of the method according to the invention, while FIG. 2 shows a pressure tank for use in the practice of the invention.

5 I fig. 1 er vist en jordtank 2, som er under sletning ved fremgangsmåden ifølge opfindelsen. Jordtanken 2 er nedgravet i væsentlig afstand fra vej. En oversidedel 4, fortrinsvis ved tankens indfyldningsstuds, dvs. modsat en udluftningsstuds 6, er gravet fri, og en åbning 8 er skåret i overside-10 delen 4. En indsprøjtningsdyse 10 i form af et vinkelbukket rørstykke er indført gennem topåbningen 8 uden at udfylde denne. Indsprøjtningsdysen 10 er monteret ved enden af en relativ lang og tyk slange 12, hvorigennem fyldmateriale i form af almindeligt bakkesand 14 indsprøjtes for udfyldning 15 af tanken 2.5 In FIG. 1, a soil tank 2 is shown which is being erased by the method according to the invention. The soil tank 2 is buried at considerable distance from the road. An upper side portion 4, preferably at the filling end of the tank, i.e. opposite to a vent nozzle 6, is dug free, and an aperture 8 is cut into the upper side portion 4. An injection nozzle 10 in the form of an angular tube piece is inserted through the top nozzle 8 without filling it. The injection nozzle 10 is mounted at the end of a relatively long and thick hose 12, through which filling material in the form of ordinary tray sand 14 is injected to fill the tank 2.

Ude på vejen er placeret en tryktank eller -beholder 16, som er kugleformet, fordi der til transport af sandet 14 anvendes trykluft ved et tryk på f.eks. 8 ato. Kuglebeholderen 16 ifyl-des sand fra en lastbil 18 gennem en tætforseglelig topåbning 20 20, idet sandet ifyldes kuglebeholderen manuelt eller ved hjælp af en transportindretning 22 fra lastbilen 18. På dennes lad er desuden placeret en kompressor 24, som leverer trykluft til kugletanken 16, hvorfra fyldsandet gennem en nedre udledningsåbning 26 og ved hjælp af et brobrydende 25 røre- eller piskeværk 28 (fig. 2) transporteres frem til jordtanken 2 og indsprøjtes deri gennem slangen 12 og dysen 10. Kugletanken 16 har en diameter på ca. 100 cm, dvs. at den kan indeholde ca. 500 1 sand pr. portion. Når kugletanken 16 er tømt, genfyldes denne med sand fra lastbilen 18, og 30 denne cyklus gentages indtil jordtanken 2 er helt udfyldt med sand. Topåbningen 8 i jordtanken 2 er lavet så stor, at rigelig ventilering af drivluften under tankfyldningen løbende finder sted.Out on the road is a pressure tank or container 16, which is spherical, because for the transport of the sand 14 compressed air is used at a pressure of e.g. 8 ato. The ball container 16 is filled with sand from a truck 18 through a tightly sealed top opening 20 20, the sand being filled manually by the ball container or by means of a transport device 22 from the truck 18. A compressor 24 which supplies compressed air to the ball tank 16 is also placed on its load. from which the filling sand through a lower discharge opening 26 and by means of a bridge-breaking 25 stirrer or whip 28 (Fig. 2) is conveyed to the ground tank 2 and injected therein through the hose 12 and the nozzle 10. The ball tank 16 has a diameter of approx. 100 cm, ie that it may contain approx. 500 1 sand per portion. When the ball tank 16 is emptied, it is refilled with sand from the truck 18, and this cycle is repeated until the soil tank 2 is completely filled with sand. The top opening 8 in the soil tank 2 is made so large that there is continuous ventilation of the propellant air during the tank filling.

Ved forsøg, hvor der blev anvendt almindeligt bakkesand, og hvor afstanden fra kugletanken 16 til jordtanken 2 var ca.In experiments where ordinary ground sand was used and the distance from the ball tank 16 to the soil tank 2 was approx.

80 meter, blev anvendt trykluft ved 8 ato og en luftmængde o på ca, 6 m /min, og jordtanken 2, som i dette tilfælde var 5 en overjordisk forsøgstank med passende inspektionsåbninger blev helt udfyldt med tætpakket sand, som i en kontrolperiode på nogle måneder ikke har sat sig nævneværdigt.80 meters, compressed air was used at 8 ato and an air flow o of about 6 m / min, and the soil tank 2, which in this case was an overhead test tank with suitable inspection openings, was completely filled with tightly packed sand, which in a control period of some months have not sat down significantly.

Til brug ved fremgangsmåden er udviklet den i fig. 2 mere tydeligt viste kugletank 16, der som nævnt har en diameter 10 på ca. 100 cm eller et rumfang på ca. 500 1. Fyldmaterialet eller sandet 14 ifyldes gennem topåbningen 20, der er forsynet med et tætsluttende dæksel 28 med en lukkemekanisme 30.For use in the method, the one shown in FIG. 2 shows more clearly the ball tank 16 which, as mentioned, has a diameter 10 of approx. 100 cm or a volume of approx. 500 1. The filler material or sand 14 is filled through the top opening 20 provided with a tightly fitting cover 28 with a closure mechanism 30.

Når sandet 14 er ifyldt kugletanken 16, sættes denne under tryk, idet trykluft fra kompressoren 24 (fig. 1) tilsluttes 15 ved 32, således at der etableres et drivtryk over sandet 14 i tanken 16 via rørforbindelsen 33. Samtidigt startes et røre-eller piskeværk 34, der drives af en udvendig hydraulik- eller trykluftmotor 36, og som sørger for let tilstrømning af sand til en injektordyse 40 umiddelbart ud for udtømningsåbningen 20 26 af kugletanken 16. Injektordysen 40 er udformet i et til slutningsrør 42 for slangen 12. Kugletanken 16 er anbragt på et kørestativ og i Øvrigt beregnet til bugsering efter lastbil. Kugletanken 16 kan også være indrettet til anbringelse direkte på et lastbillad eller på en sædvanlig anhænger. Af 25 hensyn til let genfyldning af kugletanken 16 er det hensigtsmæssigt, at denne ikke anbringes i for stor højde, uanset det ligger inden for opfindelsens rammer at anvende enhver facon på tryktank eller ethvert genfyldningsarrangement for denne.When the sand 14 is filled to the ball tank 16, it is pressurized, with compressed air from the compressor 24 (Fig. 1) being connected 15 at 32, so that a driving pressure is established over the sand 14 in the tank 16 via the pipe connection 33. At the same time a stirring or whipping plant 34, driven by an external hydraulic or compressed air motor 36, which provides for easy flow of sand to an injector nozzle 40 immediately adjacent the discharge port 20 26 of the ball tank 16. The injector nozzle 40 is formed in a tubing 42 end tube 42. 16 is placed on a tripod and otherwise designed for towing by truck. The ball tank 16 may also be arranged to be mounted directly on a truck or on a conventional trailer. For ease of refilling the ball tank 16, it is desirable that it not be placed at excessive height, regardless of the scope of the invention to apply any shape to a pressure tank or any refilling arrangement therefor.

Ved første opfyldning af tryktanken 16 for en given udfyld-30 ningsopgave kan ifyldes en passende mængde af et olieabsorberende og/eller olieneutraliserende pulver, men tryktanken 16 kan i stedet være forsynet med en separat forrådsbeholder for sådan tilsatsmateriale, idet der endog kan findes organer til tilledning af tilsatsmaterialet til tilslutningsrøret 42 35 eller injektordysen 40.Upon initial filling of the pressure tank 16 for a given filling task, a suitable amount of an oil absorbing and / or oil neutralizing powder may be filled, but the pressure tank 16 may instead be provided with a separate storage container for such additive material, and there may even be means for feeding the filler material to the connecting tube 42 35 or the injector nozzle 40.
