Definitions

  • the present invention relates to a reservoir for confinement of any fluid, such as in particular a liquefied gas, of the type comprising a concrete enclosure buried in the ground, a slab of bottom and a dome of covering as well as an envelope waterproof which delimits inside the structure formed by the enclosure, the slab and the dome of covering a loading space for the liquid.
  • a fluid such as in particular a liquefied gas
  • Buried tanks of this type allow, for compared to conventional "aerial" tanks, reduce the floor space and limit the impact on the installation environment, while providing a high level of security.
  • Document FR-A-1407117 describes a buried tank of which the outer wall of the enclosure structure extends to the bottom slab. If such a tank was installed in a coastal area, it would be exposed at considerable water pressure and should have important dimensions to be able to resist these constraints. On the other hand, the covering dome of this tank is produced as a separate part and rests on the upper end of the enclosure. To reinforce the latter, a cable is wound around the enclosure. In addition, an embankment adjacent to the external wall is used to ensure post-stress of this wall. Therefore, the known reservoir has a complex and expensive structure.
  • the object of the present invention is to provide a underground tank whose structure is both simple, resistant and inexpensive.
  • the reservoir according to the invention has the features that are set out in the claim 1.
  • the base of the enclosure extends at least up to a substantially waterproof layer, infiltration of groundwater into space by below the bottom slab and thus the water pressure that can be exerted on it are reduced. Thanks to this reduction in pressure, the thickness of the slab background can be reduced.
  • the dome serves as a means of reinforcing the enclosure which can therefore be formed by a wall unique reduced thickness.
  • document FR-A-2188654 describes certainly a reservoir whose annular wall extends beyond from the bottom slab but up to a layer of soil can act as a foundation layer without be waterproof.
  • the enclosure has a complex structure with successively radially a multitude of layers and the upper end of this complex enclosure and the dome cover are made in the form of parts separate.
  • Figure 1 is a cutaway view of a tank buried in accordance with an embodiment of the invention.
  • Figure 2 is a vertical sectional view along a diameter of the tank in Figure 1.
  • FIG. 3 is an enlarged view of the detail designated by III in Figure 2.
  • Figure 4 is an enlarged view of the detail designated by IV in Figure 2.
  • Figure 5 shows a vertical sectional view of a arrangement of buried tanks in accordance with the invention.
  • the general reference numeral 1 indicates a buried tank.
  • the tanks 1 are intended for the containment of liquid natural gas.
  • many other types of fluids can also be stored or "stored" in such tank.
  • Each tank 1 is a buried tank of the so-called type "membrane". More specifically, the reservoir 1 comprises an external concrete enclosure 2, which is at least partially buried in the ground, itself designated by the reference S in the figures. Enclosure 2 which is roughly cylindrical, delimits in the soil S a excavation or cavity of corresponding shape.
  • the buried tank 1 has a rigid structure that is to say a structure guaranteeing stability and the holding of the tank 1 under the effect of the constraints that can be applied to it.
  • the rigid structure here is provided with a covering dome 3, arranged at the above enclosure 2 and projecting from floor S.
  • the structure rigid tank 1 also has a slab of bottom 4, arranged opposite the dome 3 or the top of the tank 1, and the shape of which corresponds substantially to that of the cavity defined by the external enclosure 2.
  • the covering dome 3 as well as the bottom slab 4 are concrete structures sunk and scrapped.
  • envelope 5 which delimits inside the cavity defined by the external enclosure 2 as well as by the dome 3 and the slab 4, a loading and containment space for the fluid to store.
  • the casing 5 is waterproof and has also for the function of thermally insulating fluid stored in tank 1, the elements structural concrete 2, 4 and possibly 3.
  • the external enclosure 2 has the form of a thick and substantially watertight wall, with which the covering dome 3 is advantageously come of matter, so that they constitute, with the bottom slab 4, the rigid structure of the tank 1 corresponding.
  • the external enclosure 2 extends deep into the ground to close proximity a substantially impermeable layer SI thereof, so that water infiltration inside the cavity defined by tank 1 are greatly minimized.
  • enclosure 2 projects positively inside even of the naturally impermeable layer SI of the ground.
  • the efforts produced by the water contained in the ground S and tending to raise the slab 4 are greatly reduced.
  • the tank 1 is simpler in constitution and requires a great deal less material for its manufacture, than equivalent tanks of the prior art.
  • the thickness (and therefore the mass) of this bottom slab 4 can also be minimized. As seen in the example of Figures 1 and 2, the bottom slab 4 even has a thickness less than that of the external speaker 2.
  • the thickness of the external enclosure 2 can be of the order of 2.20 m and that only about 1 m from the bottom slab.
  • the thickness of the external enclosure and of the rigid vertical structure is more than 3 m, while the bottom slab can reach 7 m in height.
  • this bottom slab 4 has the shape of a slab in reinforced concrete which rests freely on the one hand against one or more stops integral with the enclosure 2, and on the other hand on a drainage system 6.
  • the drainage system 6 comprises essentially a second raft made up of aggregates porous arranged on the bottom of the cavity excavated in soil S. So when water seeps into inside enclosure 2, it is drained at through the second raft 6 towards pumps refoulement (not shown). As illustrated in the figure 2, these pumps deliver in one or more wells P formed in the soil S near the reservoir 1, via conduits 66 made at through enclosure 2.
  • the tank 1 is provided a frost protection device for its elements in concrete.
  • This device comprises on the one hand pipes 64 ( Figure 2) circulation of a hot fluid, as for example water, provided under the bottom slab 4, that is to say inside the second raft 6, and on the other hand heating electric cables 28 ( Figure 2) conventional, arranged in tubes in galvanized steel, themselves embedded in the concrete of the external enclosure 2 substantially up to the level of the slab 4.
  • enclosure 2 is in reinforced concrete molded directly into the soil S.
  • this enclosure 2 is made in digging a shaped trench in the ground corresponding, then by molding a concrete of composition appropriate in the trench, after having disposed of reinforcement cages as well as cables 28 of heater.
  • a wall can for example be obtained using an apparatus of the type of that designated by the name "Hydrofraise” and developed by the Soletanche Company. This type of equipment allows to make concrete walls from 70 to 80 m depth, under conditions and with tolerances very precise dimensions (approximately 1 for 1000).
  • a coating or siding is applied to the internal face or excavation of enclosure 2, for example by spraying concrete onto a wire mesh itself fixed by anchoring on this enclosure.
  • the facing the following thickness the example mentioned above is around 0.15 m provides a smoother surface finish of the excavation face. Essentially, the surface finish thus obtained must allow good fixation of envelope 5 on concrete, like this will be better explained below.
  • a beam of corresponding shape 32 At the top of the external enclosure 2, a beam of corresponding shape 32.
  • this so-called crowning beam is integrated into both enclosure 2 and the dome of overlap 3, which allows good transmission efforts inside the concrete structure, as well that a reinforcement of the external enclosure 2.
  • dome cover 3 is anchored at the top of enclosure 2 via beam 32.
  • a metal dome 35 called to be part of the envelope 5, forming an internal coating of the dome 3 is made from a truss of beams metal plates on which are welded sheet metal.
  • the dome 35 which defines a waterproof surface corresponding to dome 3, is rendered secured to beam 32.
  • concrete is poured until dome 3 is obtained.
  • the thickness of the concrete of this dome of overlap 3 varies from 0.5 to 1.0 m from its center to its periphery. It is at this peripheral that the concrete of dome 3 is connected to that of the beam 32. It goes without saying that the dome 35 remains within the tank 1 after pouring the concrete, and is therefore fixed to the dome 3, which itself came with the beam 32 and the thick enclosure 2.
  • the metal dome 35 is integral with dome 3 and is part of the envelope waterproof and insulation 5.
  • the envelope 5 comprises a metal membrane which is welded on a shoulder 352, itself integral with the periphery of dome 35. This welding is obviously continuous and airtight, so this membrane and the dome constitute a sealed containment.
  • the membrane metal of enclosure 5 is designated at 54 and 52. also sees that envelope 5 has a layer thermal insulation 55.
  • the membrane consists by austenitic stainless steel sheets of a thickness of the order of 1.2 mm, welded together watertight and is fixed to concrete by through layer 55. These sheets which form containment pocket, ribbed to resist deformations linked to mechanical stresses and applied to them by the fluid stored in tank 1.
  • the insulation layer 55 consists of one or more thicknesses of rigid panels 57, for example of plywood, as well as by at least one thickness of panels of plastic foam 56 preferably raincoat.
  • the layer 55 comprises, starting from the concrete wall a series of foam panels 56, sandwiched between two plywood thicknesses 57.
  • the panels 57 have the function of distributing the stresses applied to the insulating layer 55, and therefore allow a better positioning thereof on concrete walls.
  • insulators 56 are for example constituted by blocks closed cell foam, polyurethane based (PU) or polyvinyl chloride (PVC).
  • the foam panels 56 can be waterproof and hermetically connected to each other by waterproof connections, in order to constitute a layer additional insulation, continuous and hermetic.
  • One of the faces of the panels 57 facing the concrete is glued to the latter for example using a layer of suitable adhesive material.
  • the layer of adhesive material is continuous and waterproof, so that it contributes to sealing tank 1.
  • a suspended roof 36 which is fixed with tie rods or cables 37 to the dome 35 and therefore to the dome 3, is interposed between the latter and the external enclosure 2.
  • This roof 36 is constituted by a lattice of beams in aluminum, itself covered with a layer of insulation 365, for example in glass wool.
  • the suspended roof 36 comes into contact by its periphery with the envelope insulation 5, of which it is a part.
  • this suspended roof 36 and its woolen layer glass 365 allows thermal insulation of the fluid contained in the tank 1, the dome 3 and its dome 35, so as to keep these elements roughly ambient temperature.
  • the reference numeral 70 designates in the figures of loading and unloading lines fluid to be stored in tank 1. These pipes 70 which are of conventional type will not described in more detail here.
  • the wall 20 is produced by molding in a trench of the ground, a material waterproof and deformable, such as for example concrete plastic or sealing grout.
  • a material waterproof and deformable such as for example concrete plastic or sealing grout.
  • four tanks 1 arranged in a square can be confined inside a buried wall 20 of shape cylindrical or parallelepiped.
  • this wall 20 has a thickness at most equal to that of the enclosures external 2 of the corresponding tanks 1, and its base protrudes deeper than these in floor.
  • the wall 20 extends up to the interior of the substantially impermeable layer SI.
  • the reference numeral 201 designates in Figure 5 a pumping system of the contained water inside the wall 20. It is understood that such a system 201 has the function of evacuating from the wall 20, so that its level is constantly maintained in below the level of the rafts 4 of the tanks 1 surrounded by this wall 20. Since the infiltrations of water in the ground where tanks 1 are buried are minimized by the presence of the sealed wall 20, the pumping system 201 of the arrangement of the figure 5, can be very simple, which makes this arrangement particularly economical.
