Description

L'invention concerne la réalisation d'un appui d'un élément sur une surface d'appui et elle s'applique en particulier à l'appui d'une structure sur un fond sous-marin, cette structure étant partiellement ou totalement immergée.The invention relates to the production of support for an element on a support surface and it applies in particular to the support of a structure on an underwater bottom, this structure being partially or totally submerged.

Il est connu de réaliser un appui en gonflant une paroi élastique souple au moyen d'air comprimé de façon à constituer un coussin puis en remplissant le coussin avec des agrégats et enfin en durcissant le coussin par injection d'un fluide hydraulique, comme décrit dans la publication FR-A 2 054 885.It is known to make a support by inflating a flexible elastic wall by means of compressed air so as to constitute a cushion then by filling the cushion with aggregates and finally by hardening the cushion by injection of a hydraulic fluid, as described in publication FR-A 2,054,885.

Dans cette publication, la paroi souple gonflable est une paroi qui ferme un logement étanche du côté de la surface d'appui et une réserve d'agrégats est réalisée au-dessus de ce logement et est séparée du logement par une paroi que l'on escamote le moment venu lorsqu'on désire faire tomber les agrégats dans le logement.In this publication, the inflatable flexible wall is a wall which closes a sealed housing on the side of the bearing surface and a reserve of aggregates is produced above this housing and is separated from the housing by a wall which is retracts when the time comes when you want to drop the aggregates into the housing.

Cette technique présente un certain nombre d'inconvénients :

  • - le logement doit être particulièrement bien étanche pour permettre le gonflement de la paroi au moyen d'air comprimé,
  • - la paroi de séparation entre le logement et la réserve d'agrégats doit être suffisamment solide pour supporter le poids des agrégats et cependant facilement escamotable, ce qui entraîne des complications de construction,
  • - la paroi gonflable doit être très élastique si l'on désire lui donner par gonflage une grande surface et une telle paroi élastique est sensiblement coûteuse, d'autant plus que la paroi élastique doit pouvoir résister à l'impact des agrégats.
This technique has a number of drawbacks:
  • - the housing must be particularly well sealed to allow the wall to swell by means of compressed air,
  • - the partition wall between the housing and the aggregate reserve must be strong enough to support the weight of the aggregates and yet easily retractable, which leads to construction complications,
  • - The inflatable wall must be very elastic if one wishes to give it by inflation a large area and such an elastic wall is substantially expensive, especially since the elastic wall must be able to withstand the impact of aggregates.

La présente invention vise à éviter ces inconvénients.The present invention aims to avoid these drawbacks.

On y parvient, selon l'invention, en fixant à l'élément un sac plié,dépliable à l'extérieur de l'élément en vis-à-vis de la surface d'appui,et en injectant dans ce sac un fluide hydraulique durcissable pour provoquer le déploiement du sac et son remplissage.This is achieved, according to the invention, by attaching to the element a folded bag, unfoldable outside of the element opposite the bearing surface, and by injecting into this bag a hydraulic fluid curable to cause deployment of the bag and its filling.

Dans une réalisation préférée, on loge le sac à l'état plié dans un logement de l'élément, ce logement étant muni d'une ouverture dirigée vers la surface d'appui et on ferme cette ouverture par un capot provisoire.In a preferred embodiment, the bag is housed in the folded state in a housing of the element, this housing being provided with an opening directed towards the bearing surface and this opening is closed by a temporary cover.

Dans une réalisation avantageuse, on fixe le capot provisoire de façon qu'il soit chassé par la poussée du sac sous l'effet de l'injection du fluide hydraulique dans le sac. La fixation provisoire du capot est assurée par exemple par un coincement ou par un collage faible ou par tout autre moyen.In an advantageous embodiment, the temporary cover is fixed so that it is driven out by the pushing of the bag under the effect of the injection of the hydraulic fluid into the bag. The temporary fixing of the cover is ensured for example by jamming or by weak bonding or by any other means.

Le sac plié est par exemple un tissu armé, une matière plastique, une tôle mince, etc... Bien entendu, on peut, si on le désire, utiliser une matière élastique pour constituer le sac mais ceci n'est pas à priori nécessaire car l'augmentation de surface est essentiellement due au déploiement du sac lorsqu'il passe de l'état plié à l'état déplié.The folded bag is for example a reinforced fabric, a plastic material, a thin sheet, etc ... Of course, one can, if desired, use an elastic material to constitute the bag but this is not a priori necessary because the increase in surface area is mainly due to the deployment of the bag when it goes from the folded state to the unfolded state.

Les figures du dessin joint illustrent schématiquement et à titre d'exemple la présente invention.

  • Les figures 1 à 3 représentent trois faces successives de la mise en oeuvre du procédé, et
  • La figure 4 est une vue agrandie du sac plié.
The figures of the accompanying drawing illustrate schematically and by way of example the present invention.
  • FIGS. 1 to 3 represent three successive faces of the implementation of the method, and
  • Figure 4 is an enlarged view of the folded bag.

On a supposé, sur les figures, que l'élément dont on veut réaliser l'appui est un caisson 1 que l'on veut mettre en appui sur un fond sous-marin 10.It has been assumed, in the figures, that the element for which the support is to be produced is a box 1 which is to be supported on an underwater bottom 10.

On munit la structure 1 de plusieurs logements 2 qui présentent chacun une ouverture sur la face de dessous de la structure 1, ces ouvertures étant tournées vers la surface d'appui 10. Les logements sont fermés par des capots 6 qui sont maintenus par friction. Chaque logement contient une nappe pliée 3 qui constitue avec les parois du logement une capacité étanche 4.The structure 1 is provided with several housings 2 which each have an opening on the underside of the structure 1, these openings being turned towards the bearing surface 10. The housings are closed by covers 6 which are held by friction. Each housing contains a folded sheet 3 which constitutes, with the walls of the housing, a sealed capacity 4.

Des tubulures 7, reliées à une source de fluide hydraulique sous pression 8,communiquent avec les logements par des entrées 5 pour pouvoir introduire dans les capacités le fluide hydrauliqueTubing 7, connected to a source of pressurized hydraulic fluid 8, communicates with the housings by inlets 5 so as to be able to introduce the hydraulic fluid into the capacities

La structure 1 est amenée au-dessus de la surface 10 par un navire 9 ou équivalent auquel la structure est suspendue par des câbles 11 ou par tout autre moyen. On commence l'injection du fluide hydraulique dans les capacités 4 et sous l'effet de l'injection les nappes 3 commencent à se déplier d'abord à l'intérieur des logements puis chassent par poussée les capots 6 et se déploient ensuite à l'extérieur des logements. Simultanément, on descend la structure 1 à proximité de la surface 10 pour que les sacs constitués par les nappes dépliées et rempli de fluide hydraulique viennent au contact de la surface 10 et en épouse le profil.The structure 1 is brought above the surface 10 by a ship 9 or equivalent to which the structure is suspended by cables 11 or by any other means. The injection of the hydraulic fluid into the capacities 4 begins and under the effect of the injection the plies 3 begin to unfold first inside the housings then push out the covers 6 and then deploy to the exterior of housing. Simultaneously, the structure 1 is lowered close to the surface 10 so that the bags formed by the unfolded sheets and filled with hydraulic fluid come into contact with the surface 10 and follow the profile thereof.

La nappe dépliée assure un appui dès qu'elle est pleine avant même la prise du matériau hydraulique en sorte qu'il est possible à la fois d'utiliser un matériau. hydraulique très fluide et de lâcher le poids de la structure avant que ce matériau ait fait prise. Sur la figure 3, l'injection est terminée et les nappes 3 ont pris leur position de service. Selon les cas, les conduits d'alimentation 7 sont remplis ou non par le matériau injecté durci.The unfolded ply provides support as soon as it is full even before the hydraulic material sets, so that it is possible both to use a material. hydraulic fluid and release the weight of the structure before this material has set. In FIG. 3, the injection is finished and the plies 3 have assumed their service position. Depending on the case, the supply conduits 7 are filled or not with the cured injected material.

On notera que le matériau hydraulique n'a aucune difficulté à remplir la nappe dépliée alors que dans le cas de la réalisation décrite dans la publication FR-A 2 054 885 les agrégats présents dans le coussin avant injection du matériau hydraulique constituent un obstacle à la répartition homogène du matériau hydraulique dans le coussin.It will be noted that the hydraulic material has no difficulty in filling the unfolded ply whereas, in the case of the embodiment described in publication FR-A 2 054 885, the aggregates present in the cushion before injection of the hydraulic material constitute an obstacle to the homogeneous distribution of hydraulic material in the cushion.

L'invention n'est pas limitée à une forme ou à une position particulière ou à un nombre particulier d'appuis ni à un choix particulier de moyens pour injecter le fluide hydraulique dans les capacités.The invention is not limited to a particular shape or position or to a particular number of supports nor to a particular choice of means for injecting the hydraulic fluid into the capacities.
