Description
Citerne métallique entouré d'une enveloppe en béton.Metallic tank surrounded by a concrete envelope.
La présente invention est relative aux citernes métalliques, destinées notamment à contenir des fluides sous pression. The present invention relates to metal tanks, intended in particular to contain pressurized fluids.
La distribution de l'énergie1 notamment dans les campagnes et périphéries urbaines, a vu se développer depuis plusieurs décennies un nombre très important de petites citernes, de structure métallique, destinées à contenir des gaz liquéfiées butane ou propane, ou leur mélange, pour alimenter en énergie des habitations individuelles ou de petits ensembles. The distribution of energy1, particularly in the countryside and urban outskirts, has seen the development for several decades of a very large number of small tanks, of metallic structure, intended to contain liquefied butane or propane gases, or their mixture, to supply energy of individual dwellings or small complexes.
Ces citernes sont généralement situées à proximité des constructions dans les jardins, posées sur des dalles et sont ravitaillées par des camions-citernes équipés de volucompteurs. These tanks are generally located near constructions in the gardens, laid on slabs and are supplied by tank trucks equipped with volume meters.
Si cette forme de distribution continue a connaitre un grand succès dans la plupart des pays, on observe des difficultés liées à l'exiguïté des surfaces de jardin disponibles, ou à des notions de sécurité de l'environnement qui impliquent des contraintes de distance de ces récipients, par rapport aux habitations, aux voies de passage, aux limites de propriétés, etc., de plus en plus contraignantes. If this form of distribution continues to be very successful in most countries, there are difficulties linked to the small size of the available garden areas, or to notions of environmental security which imply distance constraints from these containers, with regard to dwellings, passageways, property limits, etc., which are increasingly restrictive.
I1 existe des citernes que l'on peut enfouir dans le sol et qui, à simple ou double paroi de protections appropriées pour être en contact avec le sol, permettent des installatipns plus proches des habitations ou des limites de propriétés, sans occuper une surface aerienne aussi importante que dans le cas précédent. There are tanks that can be buried in the ground and which, with single or double walls of suitable protections to be in contact with the ground, allow installations closer to dwellings or property limits, without occupying an aerial surface as important as in the previous case.
Toutefois, ce type de stockage présente un certain nombre d'inconvénients - il est, de par sa conception, relativement cher en
raison de matériaux de protection d'un cotit élevé - sa mise en place, si l'on ne veut pas blesser le revê
tement, est souvent malaisée en raison de precautions
nombreuses et difficiles à prendre pour éviter d'éven
tuelles dégradations du revêtement protecteur, soit a
l'enfouissement du réservoir, soit par les agents
agressifs solides ou liquides qui intéressent le mi
lieu où il est implanté - de plus, un lestage important contre la poussée des
eaux est indispensable et contribue à accroître le
prix d'une telle conception.However, this type of storage has a number of drawbacks - it is, by design, relatively expensive in
because of protective materials of a high cost - its installation, if one does not want to hurt the dream
is often awkward due to precautions
many and difficult to take to avoid events
damage to the protective coating, i.e. a
burial of the tank, either by agents
aggressive solid or liquid that interest the mi
where it is located - in addition, a significant ballast against the push of
water is essential and helps to increase the
price of such a design.
De -nombreux Etats exigent des propriétaires ou utilisateurs de ces réservoirs, des visites extérieures qui obligent à réaliser des excavations, quand ce n'est pas à ressortir complètement le réservoir de son enfouissement. -Many states require owners or users of these tanks, external visits that require excavation, when it is not to fully remove the tank from its burial.
Toutes ces considérations limitent singulièrement le développement de cette forme de stockage qui, par ailleurs, aux plans de l'esthétique et de la sécurité, notamment en cas d'incendie, présente des avantages indiscutables par rapport aux classiques réservoirs aériens. All these considerations singularly limit the development of this form of storage which, moreover, in terms of aesthetics and safety, in particular in the event of a fire, has indisputable advantages compared to conventional overhead tanks.
Pour remédier à ces difficultés, l'invention décrite consiste à entourer la citerne métallique, soit d'une façon directement adhérente, soit avec un liant (tel que des goudrons ou des corps siliconés) pour pouvoir directement enfouir la citerne à l'intérieur de son enveloppe en béton dans le sol, sans autre moyen de protection. To overcome these difficulties, the invention described consists in surrounding the metal tank, either in a directly adherent manner, or with a binder (such as tars or silicone bodies) in order to be able to directly bury the tank inside its concrete envelope in the ground, without any other means of protection.
Dans ce cas, l'enveloppe remplit des fonctions multiples - elle assume d'abord une protection contre les agres
sions mécaniques et chimiques du milieu souterrain,
par rapport aux parois d'acier du réservoir propre
ment dit - elle constitue également une isolation en cas d'élé
vation accidentelle importante de la température du
milieu ou de la surface du sol, par exemple en cas
d'incendie intéressant la surface proche du stockage.In this case, the envelope fulfills multiple functions - it first assumes protection against attacks
mechanical and chemical ions in the underground environment,
relative to the steel walls of the clean tank
ment says - it is also an insulation in case of elé
significant accidental change in temperature of the
middle or ground surface, for example in case
of fire affecting the area near the storage.
L'enveloppe en béton, spécialement conçue pour protéger et isoler le réservoir métallique des agressions extérieures, constitue par son poids intrinsèque, un lestage suffisant pour supprimer les traditionnels lestages dont on est obligé d'équiper les réservoirs métalliques classiques pour leur éviter de remonter du sol en cas de poussée des eaux. The concrete shell, specially designed to protect and isolate the metal tank from external aggressions, constitutes, by its intrinsic weight, sufficient ballasting to remove the traditional ballasting with which it is necessary to equip conventional metal tanks to prevent them from rising from the ground in the event of water surge.
Ce type de protection simple, robuste et bon marché s'accommode fort bien des manipulations souvent brutales observées dans les chantiers de génie civil, notamment lors du transport et de la manipulation des ouvrages, ou lors de la mise en place avec les engins de chantiers. La couche de béton enfermant la citerne, est d'une épaisseur telle qu'elle constitue un bouclier de protection (l'épaisseur de béton étant judicieusement déterminée, tant pour assurer cette protection, que pour donner une isolation et un lestage suffisant du réservoir). This simple, robust and inexpensive type of protection very well accommodates the often brutal handling observed in civil engineering sites, in particular during the transport and handling of works, or when setting up with construction equipment . The layer of concrete enclosing the tank is of a thickness such that it constitutes a protective shield (the thickness of concrete being judiciously determined, both to ensure this protection, and to give sufficient insulation and ballasting of the tank) .
Diverses conceptions peuvent être employées selon la taille des récipients et les moyens de production et de manutention dont on dispose. On énumère ci-après quelques solutions qui peuvent avantageusement être utilisées, en précisant que ces'descriptions ne sont nullement limitatives et ne représentent que certaines des nombreuses variantes de réalisations possibles. Various designs can be used depending on the size of the containers and the means of production and handling available. A few solutions which can advantageously be used are listed below, by specifying that these descriptions are in no way limiting and represent only some of the many possible variants.
A la figure 1, une enveloppe en béton 1 est directement appliquée sur la citerne métallique 2 et solidarisée de celle-ci par des accrochages appropriés, tels que grillages soudés, goujons, ceintures métalliques noyées dans l'agrégat, etc. In FIG. 1, a concrete casing 1 is directly applied to the metal tank 2 and secured to it by suitable hooks, such as welded mesh, studs, metal belts embedded in the aggregate, etc.
Dans ce cas, les appareils de mesure (régulation de débit 3, de pression et de niveau 4) sont généralement fixés à la partie supérieure dans un orifice 5 de forme et de dimension appropriées, en prévoyant d'ailleurs des passages étanches 6 pour les canalisations électriques, ou de fluides à travers ces parois et venant affleurer ou légèrement dépasser la surface du sol 12 ou se trouve enfoui le récipient. I1 est alors procédé à un moulage sur le récipient terminé et vérifié de construction métallique. L'épaisseur de béton 1 contribue a la résistance de la citerne 2 par l'effet de frette autour d'elle. In this case, the measuring devices (flow control 3, pressure and level 4) are generally fixed to the upper part in an orifice 5 of suitable shape and size, moreover providing for watertight passages 6 for the electrical pipes, or fluids through these walls and coming to be flush with or slightly exceed the surface of the ground 12 where the container is buried. I1 is then proceeded to a molding on the finished and verified container of metal construction. The thickness of concrete 1 contributes to the resistance of the tank 2 by the hoop effect around it.
Dans d'autres formes de conceptions (figure 2), on réalise des enveloppes en différentes formes et tron çons, assemblées par des tirants 8, avec joints d'étan chéité 13 autour de la citerne métallique 2, par exemple (figures 3 et 4) en forme de demi-coquille 7, ou en forme tubulaire 9 obturée par des fonds assemblés 10 (figure 2) ou toutes combinaisons géométriques qui permettent une réalisation et un positionnement aussi faciles que possible. In other forms of design (Figure 2), envelopes are produced in different shapes and sections, assembled by tie rods 8, with sealing joints 13 around the metal tank 2, for example (Figures 3 and 4 ) in the form of a half-shell 7, or in the form of a tube 9 closed by assembled bottoms 10 (FIG. 2) or any geometrical combination which allows production and positioning as easy as possible.
Ce type de réalisation peut être associé à un systdme automatique de détection de fluite, par observation et mesurage d'une surpression qui viendrait a se produire entre la citerne en acier et l'enveloppe de béton et qui déclencherait un signal d'alerte au moyen d'un capteur de pression interposé entre la citerne et l'enveloppe. This type of embodiment can be associated with an automatic leak detection system, by observation and measurement of an overpressure which would occur between the steel tank and the concrete shell and which would trigger an alert signal by means of a pressure sensor interposed between the tank and the enclosure.
