Definitions

  • gas for example compressed air, or liquid, for example petrol or oil
  • the water supply should preferably be such that no decrease in the normal ground water level occurs. The supply of water prevents the rock from being drained and since all cracks are filled with water under a higher pressure than in the chamber, the contents of the rock chamber is prevented from leaking out.
  • the artificial supply of water is carried out in a suitable manner even while the rock chamber is being blasted, the rock around the proposed rock chamber never becomes drained and the rock chamber can be taken into use immediately it is finished.
  • the artificial supply of water suitably through a series of drill holes near to the proposed rock chamber, increases the flow of water into the rock chamber but this flow of water can be kept within reasonable limits by sealing the rock in the walls of the rock chamber under construction in known manner by means of, for example, concrete injection, and by keeping the water pressure and quantity under control and at a suitable value.
  • the water is supplied to the rock under such a pressure that the water pressure in the rock nearest the rock chamber is higher than the maximum natural ground water pressure which can be achieved, i.e. it corresponds to an imagined ground water level lying higher than the surface of the ground.
  • the invention thus is principally directed to sealing a rock full of cracks by the artificial supply of water under pressure to the rock.
  • leakage of the contents of the rock chamber can be prevented by'supplying a liquid other than water, or possibly a gas, under pressure to the rock.
  • FIGS. 1 and 2 show a vertical and a horizontal section, respectively, through a rock chamber construction sealed by the method according to the invention.
  • FIGS. 3 and 5 illustrate alternative methods of carrying out the sealing.
  • FIG. 4 is a detail of FIG. 3 on a larger scale.
  • FIG. 6 shows how the sealing may be carried out with two different liquids.
  • FIGS. 1 and 2 show a number of rock chambers 1 which communicate through a shaft 2 with a power station 3 driven by a gas turbine, and through a shaft 4a and a gallery 4b with a lake 5.
  • this is used to fill the rock chambers I with compressed air, from a compressor driven by the gas turbine, so that a corresponding quantity of water is forced up through the shaft 4 to the lake 5.
  • the power station must deliver full power, water is allowed into the rock chamber 1 through the shaft 4 and the compressed air passes up through the shaft 2 to the gas turbine so that the normal air compressors need not be used.
  • the galleries 6 and drill holes 7 are prepared before or at the same time as the rock chamber, and the water pressure is applied before or at the same time as blasting of the rock chambers l is initiated.
  • the galleries 9, 10 are transport tunnels which are plugged when the construction is finished.
  • a number of holes 11 have been drilled upwardly in the roof of the rock chamber 1.
  • the drill holes can first be used for injecting the rock and the drilling is then continued to the desired depth, and a tube 12 is inserted in the upper part of the drill hole and the lower part is then sealing with a concrete plug 13.
  • Each tube 12 from the drill holes is connected to a pressure water conduit 14 and in this way a continuous over-pressure is main- 1 tained in the rock above the rock chamber 1, it is important that the drill holes I l are made and the water pressure applied gradually as the rock chamber 1 is under construction.
  • One or more drill holes 11a with pressure water tubes are therefore suitably prepared when the transport gallery 9 is blasted so that no drainage of the rock takes place.
  • FIGS. 1 5 the water has been supplied at a higher level than the rock chamber in order to eliminate the risk of leakage upwardly from the rock chamber.
  • FIG. 6 shows how the rock chamber can be screened off on all sides.
  • the rock chamber 1 is surrounded by a series of inner galleries 20 from which vertical and horizontal drill holes 22 extend, and by a series of outer galleries 21 with drill holes 23.
  • the drill holes form an inner and an outer screen of drill holes around the rock chamber and are supplied with water or some other liquid under pressure through conduits 24, 25.
  • the rock chamber may contain a substance which is not suited to be in direct contact with water, for example.
  • a suitable and effective screening system can thus be obtained, for example for underground nuclear power plants, by arranging first an inner screen containing a different fluid, a liquid or a gas, which separates the rock chamber from, for example, the pressurized water in the outer screen.
  • the rock chamber it is also feasible for the rock chamber to contain gas of liquid of quite a different temperature from the surrounding rock. If the temperature is extremely low in the rock chamber it is possible, for example, to pump a substance into the inner screen system, which does not freeze at the low temperature, but fills out all cracks around the rock chamber.
  • a method of preventing leakage during storage of a gas or a liquid in a rock chamber by artifically supplying water or other suitable fluid to the rock surrounding the rock chamber through a series of drill holes also before or during blasting of the rock chamber, according to which a number of substantially horizontal galleries are blasted at a level higher than that of the proposed rock chamber, a number of substantially horizontal holes are then drilled from these galleries, the galleries and drill holes are then filled with the suitable fluid and thereafter the rock chamber is blasted.
  • a method of preventing leakage during storage of a gas or a liquid in a rock chamber by artificially supplying water or other suitable fluid to the rock surrounding the rock chamber through a series of drill holes also before or during blasting of the rock chamber, according to which a number of substantially vertical holes are drilled in the ground surface above the proposed rock chamber, suitable fluid is supplied to these drill holes and the rock chamber is then blasted.
  • a method of preventing leakage during storage of a gas or a liquid in a rock chamber by artificially supplying water or other suitable fluid to the rock surrounding the rock chamber through a series of drill holes also before or during blasting of the rock chamber, according to which a system of galleries and drill holes leading from these galleries is constructed on all sides of the proposed rock chamber, these galleries and drill holes then being filled with said suitable fluid, and the rock chamber is then blasted.
  • a method of building a rock chamber comprising drilling a plurality of drill holes in the rock at least above the desired rock chamber, leading conduits for pressurized fluid into said drill holes, sealing said drill holes, supplying pressurized water to said drill holes so as to maintain the natural ground water level, and subsequently excavating the rock chamber while continuing the gradual supply of pressurized water to said drill holes.
