Description

Fjellrom for lagring av gasser og flytende stoffer, samt fremgangsmåte for fremstilling derav. Mountain room for the storage of gases and liquid substances, as well as methods for their production.

Foreliggende oppfinnelse vedrorer et fjellrom for lagring av gasser eller flytende stoffer samt en fremgangsmåte for å fremstille dette. The present invention relates to a mountain chamber for storing gases or liquid substances and a method for producing this.

Ved det hittil kjente fjellrom for lagring av produkter ved lave eller hoye temperaturer har man hatt store problemer med å forsterke disse slik at ikke sprekkdannelse samt medfolgende ras opptrer i fjellrommets vegger og tak. De vanligste fore-kommende metodene for forsterking av betonginnforing og/eller fjellbolter.. Begge disse metodene har imidlertid ulemper. Således slipper betongen fra fjellet ved at det ved lagring av væsker eller gasser med hoye eller lave temperaturer dannes spenninger mellom betongskiktet og fjellet. Boltene på sin . side har den ulempen at de leder varme eller kulde inn i fjellet med temperaturspenninger og sprekkdannelse som folge. In the previously known rock room for storing products at low or high temperatures, there have been major problems in reinforcing these so that cracks and subsequent landslides do not occur in the walls and roof of the rock room. The most common methods for reinforcing concrete linings and/or rock bolts. However, both of these methods have disadvantages. Thus, the concrete escapes from the rock because, when liquids or gases are stored at high or low temperatures, tensions are formed between the concrete layer and the rock. The bolts on its . side have the disadvantage that they lead heat or cold into the rock with temperature stresses and crack formation as a result.

Foreliggende oppfinnelse har til hensikt å tilveiebringe et fjellrom der de ovenfor beskrevne problemer overvinnes. The present invention aims to provide a mountain space in which the problems described above are overcome.

Dette skjer ved hjelp av fjellrom som erholdes ved de særtrekk somangis i det etterfolgende krav. This is done with the help of mountain spaces that are obtained by the special features as stated in the following requirements.

Et utforelseseksempel på oppfinnelsen skal beskrives neden-for med henvisning til de vedlagte tegninger, hvor det. skje-matisk vises et fjellrom i folge oppfinnelsen. An embodiment of the invention will be described below with reference to the attached drawings, where it. schematically shows a mountain room according to the invention.

I figuren vises et utforelseseksempel på et fjellrom 1 i folge oppfinnelsen. Dette fjellrommet 1 er dannet ved at en del av fjellet er sprengt los slik at det dannes stenblokker av ulik storrelse. Ved utforelseseksempelet i folge figuren er en viss del av det bortsprengte stenmaterialet latt tilbake i det dannede fjellrommet. Dette tilbakelagte stenmaterialet i form av stenblokker bétegnes i figuren med .2. Fjellrommet 1 skal fylles så mye med stenmateriale 2 at fjellpartiet som ved. spenningsforandringer losnes fra fjell rommets tak eller vegger forhindres i å rbre seg ved den stotte som sten-materialet 2 utover på fjellrommets 1 kontur. The figure shows an exemplary embodiment of a mountain room 1 according to the invention. This rock space 1 is formed by a part of the rock being blasted away so that boulders of different sizes are formed. In the embodiment example in the following figure, a certain part of the blasted rock material is left back in the formed rock space. This laid stone material in the form of boulders is denoted in the figure by .2. The rock space 1 is to be filled with stone material 2 so much that the rock part as wood. tension changes are released from the rock room's roof or walls are prevented from shifting by the support such as the stone material 2 outwards on the rock room's 1 contour.

Som det fremgår av.figuren, dannes det flere hulrom 3 mellom stenbldkkene som befinner seg i fjellrommet. Det er disse hulrommene 3 som danner det egentlige effektive lagringsrommet. As can be seen from the figure, several cavities 3 are formed between the stone slabs located in the rock space. It is these cavities 3 that form the actual effective storage space.

I det ovenfor beskrevne utforelseseksempelet, utgjores således f yll-legemene av deler av det stenmaterialet som.'-los-gjores ved utsprengningen av fjellrommet. Selvfølgelig er oppfinnelsen dog ikke begrenset til fyll-legemer av stenmateriale, men også andre materialer kan tenkes, for eksempel plast. Valget av material av fyll-legemene beror på hva man lagrer i det aktuelle fjellrommet. Ved 'lagring av eks-empelvis flytende gass er stenmaterialet ikke egnet som fyll-legemer, da det medgår alt for mye energi til å kjole dette til tilstrekkelig lav temperatur. I et slikt tilfelle be-nytter man seg i stedet av fyll-legemer av for eksempel plastmateriale. Ved varmtvanns-lagring vil fyll-legemene gunstig medvirke i eriergilagringssystemet. In the embodiment example described above, the fill bodies are thus made of parts of the rock material which is loosened during the blasting of the rock space. Of course, the invention is not limited to filler bodies made of stone material, but other materials are also conceivable, for example plastic. The choice of material for the fill bodies depends on what is stored in the mountain space in question. When storing, for example, liquefied gas, the stone material is not suitable as filling bodies, as it involves far too much energy to cool this to a sufficiently low temperature. In such a case, filler bodies made of, for example, plastic material are used instead. In the case of hot water storage, the filling bodies will contribute favorably to the energy storage system.

Også storrelsen av de enkelte fyll-legemene kan naturligvis varieres, men den begrensning må dog foreligge at fyll-legemene ikke får være stdrre enn at de gir fjellrommets kontur en akseptabel stotte i alle deler. The size of the individual fill bodies can of course also be varied, but there must be the limitation that the fill bodies must not be larger than they give the contour of the rock space an acceptable support in all parts.

De ovenfor beskrevne fjellrommet er således i forste rekke ment å anvendes -ved lagring eller magasinering av gasser eller væsker med slike egenskaper at forandringer i spenningene i fjellrommets veggflater kan ventes å oppstå. Ved for eks-sempel lagring av varmtvann, vil således en stadig sprekkdannelse med stennedfall som folge, forhindres. The rock chambers described above are thus primarily intended to be used - for storing or warehousing gases or liquids with such properties that changes in the stresses in the wall surfaces of the rock chamber can be expected to occur. In the case of, for example, the storage of hot water, a constant formation of cracks with subsequent stone fallout will thus be prevented.

Også i jordskjelvhjemsokte områder kan man forsterke fjellrom på den ovenfor viste måte. Even in earthquake-prone areas, you can reinforce rock spaces in the manner shown above.

Oppfinnelsen er ikke begrenset til det ovenfor beskrevne utforelseseksempel, men kan varieres litt innenfor rammen av de etterfølgende krav. The invention is not limited to the embodiment described above, but can be varied slightly within the framework of the subsequent claims.
